In developed countries, people have learned to follow efficient consumption patterns, while in developing countries, such as Iran, these patterns are not well executed. A large amount of energy is almost consumed in buildings and houses and though the consumption patterns varies in different societies, various energy policies are required to meet the consumption challenges. So far, several papers and more than ten case studies have worked on the relationship between domestic energy consumption and urban development, however these researches did not analyzed the impact of energy consumption on urban development. Therefore, this paper attempts to examine the interactions between the energy consumption and urban development by using system dynamics as the most widely used methods for complex problems. The proposed approach demonstrates the interactions using causal loop and flow diagrams and finally, suitable strategies will be proposed for urban development through simulations of different scenarios.

2000-01-01

The total energy consumption in Finland increased by less than a percent in 1999. The total energy consumption in 1999 was 1310 PJ corresponding to about 31 million toe. The electric power consumption increased moderately by 1.6%, which is less than the growth of the gross national product (3.5%). The final consumption of energy grew even less, only by 0.5%. Import of electric power increased by 19% in 1999. The import of electric power was due to the availability of low-priced electric power on the Nordic electricity markets. Nuclear power generation increased by 5% and the consumption of wood-based fuels by 3%. The increment of the nuclear power generation increased because of the increased output capacity and good operability of the power plants. Wind power production doubles, but the share of it in the total energy consumption is only about 0.01%. The peat consumption decreased by 12% and the consumption of hydroelectric power by 15%. The decrease in production of hydroelectric power was compensated by an increase import of electric power. The consumption of fossil fuels, coal, oil and natural gas remained nearly the same as in 1998. The gasoline consumption, however, decreased, but the consumption of diesel oil increased due to the increased road transport. The share of the fossil fuels was nearly half of the total energy consumption. The consumption of renewable energy sources remained nearly the same, in 23% if the share of peat is excluded, and in 30% if the share of peat is included. Wood-based fuels are the most significant type of renewable fuels. The share of them in 1999 was over 80% of the total usage of the renewable energy sources. The carbon dioxide emissions in Finland decreased in 1999 by 1.0 million tons. The total carbon dioxide emissions were 56 million tons. The decrease was mainly due to the decrease of the peat consumption. The final consumption of energy increased by 0.5%, being hence about 1019 PJ. Industry is the main consumer of energy

Comprehensively understanding water consumption behavior is necessary to design efficient and effective water use strategies. Despite global efforts to identify the factors that affect domestic water consumption, those related to domestic water use in rural regions have not been sufficiently studied, particularly in villages that have gained access to improved water supply. To address this gap, we investigated 247 households in eight villages in the Wei River Basin where three types of improved water supply systems are implemented. Results show that domestic water consumption in liters per capita per day was significantly correlated with water supply pattern and vegetable garden area, and significantly negatively correlated with family size and age of household head. Traditional hygiene habits, use of water appliances, and preference for vegetable gardening remain dominant behaviors in the villages with access to improved water supply. Future studies on rural domestic water consumption should pay more attention to user lifestyles (water appliance usage habits, outdoor water use) and cultural backgrounds (age, education).

The development of technology, technological innovations and demographic developments are known factors with respect to their impact on energy consumption. However, it is not yet very clear to what extent behavioral changes play a part in favor or to the detriment of energy consumption. In this report an outline is given of developments with respect to the level of provisions, services, amenities, etc. and related domestic behavior, as far as it concerns the consumption of energy of private households in the Netherlands in the second part of the 20th century. Therefore, this study is not about the impact of technological innovations, but about technological changes and changes in the materialistic environment, which resulted in an adjustment of the domestic situation and of several types of domestic behavior, and thus, also resulted in effects on energy consumption. Concrete subjects that are dealt with are the house, heating, personal care, and laundry. 60 refs.

Domestic fuel energy consumption in an Indian urban ecosystem

1995-01-01

Berhampur is one of the oldest and biggest towns of Orissa State where 93% of people earn their living from non-primary economic activities. The fuel consumption structure reveals an element of rural bias since the domestic sector derives 49% of its energy used for cooking and heating from biomass sources. Firewood is the only fuel used by all income groups and almost all occupations. Other traditional fuels such as dungcake, agricultural waste and leaf litter are used in the town with different degrees of dominance in various occupation groups and income classes. The inequality of income distribution is reflected in the fuel consumption structure of the rich and poor with greater dependence on non-biomass in the high income group and biomass in the low income group. Family size is an important determinant of biomass fuel use. For the urban poor, there is a relationship between income and fuel consumption. There exists scope for enlarging the biomass base by utilising the available bio-wastes and developing a green belt around the town. This requires some rural features in the urban area using new technologies. (author)

The material consumptive: domesticating the tuberculosis patient in Edwardian England

Science.gov (United States)

Mooney, Graham

2013-01-01

The proliferation of general and specialist hospitals, lunatic asylums, and workhouse infirmaries in the nineteenth century challenged the popular perception of the home as a suitable site of health care. Amidst the emergence of yet another type of institution, the tuberculosis sanatorium, tuberculosis control in the Edwardian period was re-sited and re-scaled to accommodate what might be termed a ‘preventive therapy’ of domestic space. Three interlinked perspectives demonstrate why and how this happened. First, I explore the role of the national and local state in legitimating domestic space as a scale and a site for the regulation of tuberculosis patients and prevention of the disease. Second, I investigate how tuberculosis self-help manuals promoted a technology of the self that was founded largely on the principles of sanatorium therapy but was necessarily reconfigured to reflect the social relations of domestic space. Third, I assess the marketing of consumer goods to the domiciled tuberculosis sufferer through the pages of the British Journal of Tuberculosis. It is suggested that a common tubercular ‘language’ of material consumption was fashioned in order to normalise the accumulation of possessions for use in the home. These arguments are situated in relation to recent historical research on material culture and identity at the turn of the twentieth century, which has stressed the cultivation of individuality and that the right sort of possessions appropriately arranged in domestic space signified well-regulated morality.

The main objective of this study was to evaluate whether daily consumption of caffeine-containing beverages is related to the prevalence and severity of premenstrual syndrome apart from any effects of daily total fluid consumption. A secondary objective was to determine whether daily total fluid consumption itself is related to premenstrual syndrome. The study is based on 841 responses to a questionnaire probing menstrual and premenstrual health, and daily fluid consumption, which was mailed to female university students in Oregon. Analysis of the data revealed that consumption of caffeine-containing beverages was strongly related to the prevalence of premenstrual syndrome. Among women with more severe symptoms, the relation between consumption of caffeine-containing beverages and premenstrual syndrome was dose-dependent, with prevalence odds ratios equal to 1.3 for consumers of one cup of a caffeine-containing beverage per day and increasing steadily to 7.0 for consumers of eight to 10 cups per day. The effects were apparent among both caffeine-containing tea/coffee consumers and caffeine-containing soda consumers. The observed effects were only slightly reduced when daily total fluid consumption was controlled. Daily total fluid consumption also was related to the prevalence of premenstrual symptoms although the effects were large only for consumers of 13-19 cups of fluid per day (the largest amount studied).

Evaluating the applicability of integrated domestic energy consumption frameworks in the UK

International Nuclear Information System (INIS)

Keirstead, James

2006-01-01

Domestic energy consumption (DEC) has been traditionally understood using disciplinary perspectives, focusing on specific components of the energy consumption system such as technologies or costs. However, early attempts to encourage energy conservation demonstrated that these frameworks often miss important contextual factors such as cultural values and behavioural interactions with technologies. This evidence, combined with the present need for energy policies that can address environmental, social, and economic concerns, suggests that a broader perspective is needed. Integrated frameworks of DEC were first proposed over 20 years ago but very little has been said about the ideas proposed in these papers, whether it be critiquing their form or assessing their impact on theory and practice. This paper attempts to fill this gap by examining the influence of integrated frameworks in academic literature and in UK energy policy. It is argued that a common language could stimulate renewed interest in the integrated perspective and thereby help policy makers meet these diverse goals. To this end, a flexible agent-based framework is proposed to stimulate debate and clarify the role of an integrated approach to domestic energy policy

The rapid growth of domestic oil consumption in Saudi Arabia and the opportunity cost of oil exports foregone

2012-01-01

We analyze the rapid growth of Saudi Arabia's domestic oil consumption, a nine-fold increase in 40 years, to nearly 3 million barrels per day, about one-fourth of production. Such rapid growth in consumption – 5.7% annually, which is 37% faster than its income growth of 4.2% – will challenge Saudi Arabia's ability to increase its oil exports, which are relied upon in long-term world oil projections by the International Energy Agency (IEA), US Department of Energy (DOE) and British Petroleum (BP). However, these institutions assume unprecedented slowdowns in Saudi oil consumption – from 5.7% annual growth historically to less than 2% in the future – allowing them to project increases in Saudi oil exports. Using 1971–2010 data, we estimate that the income responsiveness (elasticity) of oil consumption is at least 1.5—using both Ordinary Least Squares regression and Cointegration methods. We believe that continued high growth rates for domestic oil consumption are more likely than the dramatic slowdowns projected by IEA, DOE and BP. This will have major implications for Saudi production and export levels. - Highlights: ► We analyze the rapid growth of Saudi Arabia's domestic oil consumption, now one-fourth of production. ► Estimated income elasticity of oil demand at least 1.5, using OLS and Co-integration. ► Yet IEA, DOE and BP project unprecedented slowdowns, from 5.7% historically to below 2%, half the rate of income growth. ► Continued high growth rates are more likely, with major implications for Saudi production and export levels.

The domestic work of consumption: materiality, migration and home-making

Marta Vilar Rosales

2010-10-01

Full Text Available This article aims to discuss the potentials of an integrated approach to two significant fields of practice: materiality and migration. Based on the results of a preliminary approach to the Portuguese migrant community in Toronto and three previous ethnographies with Portuguese and Indi-Portuguese migrants conducted in Lisbon, Maputo and four Brazilian cities, it intends in particular to explore the various ways in which the home and home-making as a social and cultural process can work as a significant field to explore that relation. It will be argued that domestic materiality constitutes a particularly productive field to look at the relationships between macro-contexts and micro-practices, social formations and cultural institutions that affect and shape the life experiences of those who migrate. In order to discuss its participation in the evaluations, reconfigurations and processes of rebuilding / reconstructions that necessarily take part in all migratory movements, the work of domestic consumption will be addressed as an expression of those processes but also as a constitutive activity, i. e., the (reproduction of identity and belonging.

The Impact of Socio-Economic Indicators on Sustainable Consumption of Domestic Electricity in Lithuania

Full Text Available Lithuania is one of the EU Member States, where the rate of energy consumption is comparatively low but consumption of electricity has been gradually increasing over the last few years. Despite this trend, households in only three EU Member States consume less electricity than Lithuanian households. The purpose of this research is to analyse the impact of socio-economic factors on the domestic electricity consumption in Lithuania, i.e., to establish whether electricity consumption is determined by socio-economic conditions or population’s awareness to save energy. Cointegration analysis, causality test and error-correction model were used for the analysis. The results reveal that there is a long run equilibrium relationship between residential electricity consumption per capita and GDP at current prices as well as the ratio of the registered unemployed to the working-age population. In consequence, the results of the research propose that improvement of living standards for Lithuanian community calls for the necessity to pay particular attention to the promotion of sustainable electricity consumption by providing consumers with appropriate information and feedback in order to seek new energy-related consumption practices.

Full Text Available Information regarding domestic water consumption is vital, as the Kathmandu Valley will soon be implementing the Melamchi Water Supply Project; however, updated information on the current situation after the 2015 Gorkha Earthquake (GEQ is still lacking. We investigated the dynamics of domestic water consumption pre- and post-GEQ. The piped water supply was short, and consumption varied widely across the Kathmandu Upatyaka Khanepani Limited (KUKL branches and altitude. The reduction in piped, ground, and jar water consumption and the increase in tanker water consumption post-GEQ appeared to be due to the impact of the GEQ. However, the impact did not appear to be prominent on per capita water consumption, although it was reduced from 117 to 99 L post-GEQ. Piped, ground, and tanker water use were associated with an increase and jar water use was associated with a decrease in water consumption. Despite improvements in quantity, inequality in water consumption and inequity in affordability across wealth status was well established. This study suggests to KUKL the areas of priority where improvements to supply are required, and recommends an emphasis on resuming performance. Policy planners should consider the existing inequity in affordability, which is a major issue in the United Nations Sustainable Development Goals.

Domestic biomass burning (DBB) influences both indoor and outdoor air quality due to the multiple pollutants released during incomplete and inefficient combustion. The emissions are not well quantified because of insufficient information, which were the key parameters related to fuel consumption estimation, such as province- and year-specific percentage of domestic straw burning (P straw ) and firewood consumption (Fc). In this study, we established the quantitative relationship between rural-related socioeconomic parameters (e.g., rural per-capita income and rural Engel's coefficient) and P straw /Fc. DBB emissions, including 12 crop straw types and firewood for 12 kinds of pollutants in China during the period 1995-2014, were estimated based on fuel-specific emission factors and detailed fuel consumption data. The results revealed that the national emissions generally increased initially and then decreased with the turning point around 2007-2008. Firewood burning was the major source of the NH 3 and BC emissions; straw burning contributed more to SO 2 , NMVOC, CO, OC, and CH 4 emissions; while the major contributor changed from firewood to domestic straw burning for NOx, PM 10 , PM 2.5 , CO 2 , and Hg emissions. The emission trends varied among the 31 provinces. The major agricultural regions of north-eastern, central, and south-western China were always characterized by high emissions. The spatial variation mainly occurred in the northeast and north China (increase), and central-south and coastal regions of China (decrease). Copyright © 2018 Elsevier B.V. All rights reserved.

Future US energy demands based upon traditional consumption patterns lead to requirements which significantly exceed domestic supply

Science.gov (United States)

1975-01-01

Energy consumption in the United States has risen in response to both increasing population and to increasing levels of affluence. Depletion of domestic energy reserves requires consumption modulation, production of fossil fuels, more efficient conversion techniques, and large scale transitions to non-fossile fuel energy sources. Widening disparity between the wealthy and poor nations of the world contributes to trends that increase the likelihood of group action by the lesser developed countries to achieve political and economic goals. The formation of anticartel cartels is envisioned.

Fuels. Deliveries and consumption of fuels during 4th quarter 2001 and during 2001

International Nuclear Information System (INIS)

2002-01-01

The total volume of oil product deliveries (excluded lubricants, bitumen etc.) from the oil companies was 3 per cent higher during 2001 compared with 2000. The deliveries of motor gasoline and diesel oil increased by 1 per cent. Domestic heating oil decreased by 2 per cent and heavy fuel oils increased by 17 per cent, all compared with 2000. Under the forth quarter 2001 the deliveries of oil products (excluded lubricants bitumen etc.) was 5 per cent higher compared with the same quarter 2000. The deliveries of domestic heating oil and heavy fuel oils increased by 4 per cent and 28 per cent respectively. Motor gasoline increased by 3 per cent while the deliveries of diesel oil decreased by 1 per cent. The consumption of fuels in mining and manufacturing decreased by 5 per cent during 2001 compared with 2000. Most of the reduction came from the lower use of domestic fuel in manufacture of pulp, paper and paper products, printing and publishing. The total consumption in mining and manufacturing was unchanged during the 4 th quarter 2001 compared with the same period 2000. The consumption of domestic fuels decreased by 6 per cent and the oil consumption increased by 11 per cent. Higher consumption of fuels in electricity, gas and district heating services. The consumption of fuels in electricity, gas and district heating services increased by 14 per cent 2001 compared with 2000. The consumption of domestic fuels raised with 12 per cent and the use of fossil fuels raised with 17 per cent. The highest increasing, 27 per cent, was found within the use of oil. Electricity, gas and district heating services increased there fuel consumption with 29 per cent during the 0 quarter 2001 compared with the same period 2000. The raise can be explained with the fact that the 4th quarter 2000 was unusually warm. The increasing is found both in the use of domestic and fossil fuels

Background: Organotin compounds (OTCs) are a large class of synthetic chemicals with widely varying properties. Due to their potential adverse health effects, their use has been restricted in many countries. Humans are exposed to OTCs mostly through fish consumption. Objectives: The aim of this study was to describe OTC exposure through fish consumption and to assess the associated potential health risks in a Finnish population. Methods: An extensive sampling of Finnish domestic fish was carried out in the Baltic Sea and freshwater areas in 2005-2007. In addition, samples of imported seafood were collected in 2008. The chemical analysis was performed in an accredited testing laboratory during 2005-2008. Average daily intake of the sum of dibutyltin (DBT), tributyltin (TBT), triphenyltin (TPhT) and dioctyltin (DOT) ({Sigma}OTCs) for the Finnish population was calculated on the basis of the measured concentrations and fish consumption rates. Results: The average daily intake of {Sigma}OTCs through fish consumption was 3.2 ng/kg bw day{sup -1}, which is 1.3% from the Tolerable Daily Intake (TDI) of 250 ng/kg bw day{sup -1} set by the European Food Safety Authority. In total, domestic wild fish accounted for 61% of the {Sigma}OTC intake, while the intake through domestic farmed fish was 4.0% and the intake through imported fish was 35%. The most important species were domestic perch and imported salmon and rainbow trout. Conclusions: The Finnish consumers are not likely to exceed the threshold level for adverse health effects due to OTC intake through fish consumption.

A New System to Estimate and Reduce Electrical Energy Consumption of Domestic Hot Water in Spain

Directory of Open Access Journals (Sweden)

Alberto Gutierrez-Escolar

2014-10-01

Full Text Available Energy consumption rose about 28% over the 2001 to 2011 period in the Spanish residential sector. In this environment, domestic hot water (DHW represents the second highest energy demand. There are several methodologies to estimate DHW consumption, but each methodology uses different inputs and some of them are based on obsolete data. DHW energy consumption estimation is a key tool to plan modifications that could enhance this consumption and we decided to update the methodologies. We studied DHW consumption with data from 10 apartments in the same building during 18 months. As a result of the study, we updated one chosen methodology, adapting it to the current situation. One of the challenges to improve efficiency of DHW use is that most of people are not aware of how it is consumed in their homes. To help this information to reach consumers, we developed a website to allow users to estimate the final electrical energy needed for DHW. The site uses three estimation methodologies and chooses the best fit based on information given by the users. Finally, the application provides users with recommendations and tips to reduce their DHW consumption while still maintaining the desired comfort level.

THE RELATIONSHIP BETWEEN PRIMARY ENERGY CONSUMPTION, PRODUCTION AND GROSS DOMESTIC INCOME (GDP IN TURKEY

2013-06-01

Full Text Available The ability to reach a sustainable economic growth of countries initially depends on the usage of energy resources efficiently. But an unequal  distribution of energy resources in the world increases the dependency on energy in countries which have insufficient energy resources such as Turkey. Therefore, it has a great importance to analyze the share of imported energy resources for economic growth. The correlation between energy consumption and changes in gross domestic product, increases the importance of energy policies while determining  the economical policies of countries. In this study, the causality relationship between energy consumption, energy generation  and GDP in Turkey are examined using annual data for the period 1960-2009. Johansen Cointegration Causality Test and Vector Error Correction Mechanism (VECM is used for this study. Empirical results for the period under discussion there is a relationship between the variables and error correction mechanism based on long-term Granger causality test. It showed that  bileteral causality  with the energy consumption to GDP.

Estimating current and future global urban domestic material consumption

Science.gov (United States)

Baynes, Timothy Malcolm; Kaviti Musango, Josephine

2018-06-01

Urban material resource requirements are significant at the global level and these are expected to expand with future urban population growth. However, there are no global scale studies on the future material consumption of urban areas. This paper provides estimates of global urban domestic material consumption (DMC) in 2050 using three approaches based on: current gross statistics; a regression model; and a transition theoretic logistic model. All methods use UN urban population projections and assume a simple ‘business-as-usual’ scenario wherein historical aggregate trends in income and material flow continue into the future. A collation of data for 152 cities provided a year 2000 world average DMC/capita estimate, 12 tons/person/year (±22%), which we combined with UN population projections to produce a first-order estimation of urban DMC at 2050 of ~73 billion tons/year (±22%). Urban DMC/capita was found to be significantly correlated (R 2 > 0.9) to urban GDP/capita and area per person through a power law relation used to obtain a second estimate of 106 billion tons (±33%) in 2050. The inelastic exponent of the power law indicates a global tendency for relative decoupling of direct urban material consumption with increasing income. These estimates are global and influenced by the current proportion of developed-world cities in the global population of cities (and in our sample data). A third method employed a logistic model of transitions in urban DMC/capita with regional resolution. This method estimated global urban DMC to rise from approximately 40 billion tons/year in 2010 to ~90 billion tons/year in 2050 (modelled range: 66–111 billion tons/year). DMC/capita across different regions was estimated to converge from a range of 5–27 tons/person/year in the year 2000 to around 8–17 tons/person/year in 2050. The urban population does not increase proportionally during this period and thus the global average DMC/capita increases from ~12 to ~14 tons

Domestic demand for petroleum in OPEC countries

The literature on OPEC energy policy has focused primarily on its production and export potential. The rapidly increasing domestic demand for petroleum products in OPEC countries has often been ignored. This study estimates domestic demand for petroleum products by the major OPEC economies and forecasts consumption trends under alternative assumptions regarding economic growth and price deregulation. It concludes that product demand is generally price and income inelastic and thus domestic consumption in OPEC will continue to grow rapidly, even if domestic prices are raised closer to world levels in the near future

Householders' Mental Models of Domestic Energy Consumption: Using a Sort-And-Cluster Method to Identify Shared Concepts of Appliance Similarity.

Directory of Open Access Journals (Sweden)

Elizabeth Gabe-Thomas

Full Text Available If in-home displays and other interventions are to successfully influence people's energy consumption, they need to communicate about energy in terms that make sense to users. Here we explore householders' perceptions of energy consumption, using a novel combination of card-sorting and clustering to reveal shared patterns in the way people think about domestic energy consumption. The data suggest that, when participants were asked to group appliances which they felt naturally 'went together', there are relatively few shared ideas about which appliances are conceptually related. To the extent participants agreed on which appliances belonged together, these groupings were based on activities (e.g., entertainment and location within the home (e.g., kitchen; energy consumption was not an important factor in people's categorisations. This suggests messages about behaviour change aimed at reducing energy consumption might better be tied to social practices than to consumption itself.

2014-12-01

Full Text Available This paper analyzes a consumption scheduling mechanism for domestic appliances within a home area network. The aim of the proposed scheduling is to minimize the total energy price paid by the consumer and to reduce power peaks in order to achieve a balanced daily load schedule. An exact and computationally efficient mixed-integer linear programming (MILP formulation of the problem is presented. This model is verified by several problem instances. Realistic scenarios based on the real price tariffs commercially available in the Czech Republic are calculated. The results obtained by solving the optimization problem are compared with a simulation of the ripple control service currently used by many domestic consumers in the Czech Republic.

Background The association between consumption of caffeinated and decaffeinated coffee and risk of mortality remains inconclusive. Methods and Results We examined the associations of consumption of total, caffeinated, and decaffeinated coffee with risk of subsequent total and cause-specific mortality among 74,890 women in the Nurses’ Health Study (NHS), 93,054 women in the NHS 2, and 40,557 men in the Health Professionals Follow-up Study. Coffee consumption was assessed at baseline using a semi-quantitative food frequency questionnaire. During 4,690,072 person-years of follow-up, 19,524 women and 12,432 men died. Consumption of total, caffeinated, and decaffeinated coffee were non-linearly associated with mortality. Compared to non-drinkers, coffee consumption one to five cups/d was associated with lower risk of mortality, while coffee consumption more than five cups/d was not associated with risk of mortality. However, when restricting to never smokers, compared to non-drinkers, the HRs of mortality were 0.94 (0.89 to 0.99) for ≤ 1 cup/d, 0.92 (0.87 to 0.97) for 1.1-3 cups/d, 0.85 (0.79 to 0.92) for 3.1-5 cups/d, and 0.88 (0.78 to 0.99) for > 5 cups/d (p for non-linearity = 0.32; p for trend coffee (p for trend = 0.022). Significant inverse associations were observed between coffee consumption and deaths due to cardiovascular disease, neurological diseases, and suicide. No significant association between coffee consumption and total cancer mortality was found. Conclusions Higher consumption of total coffee, caffeinated coffee, and decaffeinated coffee was associated with lower risk of total mortality. PMID:26572796

Thermal performance behavior of a domestic hot water solar storage tank during consumption operation

2011-01-01

Transient thermal performance behavior of a vertical storage tank of a domestic solar water heating system with a mantle heat exchanger has been investigated numerically in the discharge/consumption mode. It is assumed that the tank is initially stratified during its previous heat storing/charging operation. During the discharging period, the city cold water is fed at the bottom of the tank and hot water is extracted from its top outlet port for consumption. Meanwhile, the collector loop is assumed to be active. The conservation equations in the axis-symmetric cylindrical co-ordinate have been used and discretised by employing the finite volume method. The low Reynolds number (LRN) k - ω model is utilized for treating turbulence in the fluid. The influence of the tank Grashof number, the incoming cold fluid Reynolds number and the size of the inlet port of the heat storage tank on the transient thermal characteristics of the tank is investigated and discussed. It is found that for higher values of Grashof number, the pre-established thermal stratification is well preserved during the discharging operation mode. It is also noticed that in order to have a tank with a proper thermal performance and or have least mixing inside the tank during the consumption period, the tank inflow Reynolds number and or its inflow port diameter should be kept below certain values. In these cases, the storage tank is enabling to provide proper amount of hot water with a proper temperature for consumption purposes.

The association between consumption of caffeinated and decaffeinated coffee and risk of mortality remains inconclusive. We examined the associations of consumption of total, caffeinated, and decaffeinated coffee with risk of subsequent total and cause-specific mortality among 74,890 women in the Nurses' Health Study (NHS), 93,054 women in the Nurses' Health Study II, and 40,557 men in the Health Professionals Follow-up Study. Coffee consumption was assessed at baseline using a semiquantitative food frequency questionnaire. During 4,690,072 person-years of follow-up, 19,524 women and 12,432 men died. Consumption of total, caffeinated, and decaffeinated coffee were nonlinearly associated with mortality. Compared with nondrinkers, coffee consumption of 1 to 5 cups per day was associated with lower risk of mortality, whereas coffee consumption of more than 5 cups per day was not associated with risk of mortality. However, when restricting to never smokers compared with nondrinkers, the hazard ratios (and 95% confidence intervals) of mortality were 0.94 (0.89-0.99) for 1.0 or less cup per day, 0.92 (0.87-0.97) for 1.1 to 3.0 cups per day, 0.85 (0.79-0.92) for 3.1 to 5.0 cup per day, and 0.88 (0.78-0.99) for more than 5.0 cup per day (P value for nonlinearity = 0.32; P value for trend coffee (P value for trend = 0.022). Significant inverse associations were observed between coffee consumption and deaths attributed to cardiovascular disease, neurologic diseases, and suicide. No significant association between coffee consumption and total cancer mortality was found.

Domestic water cycle systems serving as one critical component of artificial water cycle at the catchment's scale, is so closely related to public healthy, human rights and social-economic development, and has gained the highest priority in strategic water resource and municipal infrastructure planning. In this paper, three basic patterns of domestic water cycle systems are identified and analyzed, including rural domestic water system (i.e. primary level), urban domestic water system (i.e. intermediate level) and metropolitan domestic water system (i.e. senior level), with different "abstract-transport-consume-discharge" mechanisms and micro-components of water consumption (such as drinking, cooking, toilet flushing, showering or cleaning). The rural domestic water system is general simple with three basic "abstract-consume-discharge" mechanisms and micro-components of basic water consumption such as drinking, cooking, washing and sanitation. The urban domestic water system has relative complex mechanisms of "abstract-supply-consume-treatment-discharge" and more micro-components of water consumption such as bath, dishwashing or car washing. The metropolitan domestic water system (i.e. senior level) has the most complex mechanisms by considering internal water reuse, external wastewater reclamation, and nutrient recycling processes. The detailed structures for different water cycle pattern are presented from the aspects of water quantity, wastewater quality and nutrients flow. With the speed up of urbanization and development of social-economy in China, those three basic patterns are interacting, transforming and upgrading. According to the past experiences and current situations, urban domestic water system (i.e. intermediate level) is the dominant pattern based on indicator of system number or system scale. The metropolitan domestic water system (i.e. senior level) is the idealized model for the future development and management. Current domestic water system

Highlights: • The energy implications of China’s investment-driven (ID) economy are analyzed. • An expenditure-approach-based framework is applied to define the ID energy consumption. • An input–output model is built to identify the volume of China’s ID energy consumption. • Insights are gained for determining the saving potentials of China’s ID energy consumption. - Abstract: In this paper, we aim to fill the research gap by analyzing the relationship between China’s domestic investment and energy consumption, as well as related carbon emissions. First, we use an expenditure-approach-based framework to qualitatively examine the effects of China’s domestic investment on its energy consumption. Based on this framework, we define and differentiate the investment-driven energy consumption and carbon emissions from that which is driven by other economic activities. Second, we establish an allocation model to quantify China’s investment-driven energy consumption and carbon emissions. The results reveal that in 2007, China’s domestic investment contributed one third of both its energy consumption and carbon emissions. Further results show that a majority of this investment-driven energy consumption and carbon emissions, namely nine tenths of the total, is attributable to the construction and manufacturing sectors. Finally, we use the construction sector as a case to discuss how to determine the energy-saving and emission-reduction potential of improving investment-driven energy consumption practices

Energy consumption projection of Nepal: An econometric approach

Parajuli, Ranjan; Østergaard, Poul A.; Dalgaard, Tommy

2014-01-01

In energy dependent economies, energy consumption is often linked with the growth in Gross Domestic Product (GDP). Energy intensity, defined herewith, as the ratio of the total primary energy consumption (TPE) to the GDP, is a useful concept for understanding the relation between energy demand...... and economic development. The scope of this article is to assess the future primary energy consumption of Nepal, and the projection is carried out along with the formulation of simple linear logarithmic energy consumption models. This initiates with a hypothesis that energy consumption is dependent...... with the national macro-economic parameters. To test the hypothesis, nexus between energy consumption and possible determinant variables are examined. Status of energy consumption between the period of 1996 and 2009, and for the same period, growth of economic parameters are assessed. Three scenarios are developed...

Electricity consumption in Morocco: Stochastic Gompertz diffusion analysis with exogenous factors

International Nuclear Information System (INIS)

Gutierrez, R.; Gutierrez-Sanchez, R.; Nafidi, A.

2006-01-01

This paper proposes a means of using stochastic diffusion processes to model the total consumption of electrical power (including distribution and transport losses) in Morocco, as recorded by the official data for total sales published by Office Nationale de l'Electricite (ONE), the Moroccan electricity authority. Two models of univariate stochastic diffusion were used: the time-homogeneous Gompertz Diffusion Process (HGDP) and the time-non-homogeneous Gompertz Diffusion Process (NHGDP). The methodology proposed is based on the analysis of the trend function; this requires the analyst to obtain fits and forecasts for the consumption of electrical power by means of the estimated trend function (conditioned and non-conditioned). This latter function is obtained from the mean value of the process and the maximum likelihood estimators (MLE) of the parameters of the model. This estimation and the subsequent statistical inference are based on the discretised observation of the variable 'electricity consumption in Morocco', using annual data for the period 1980-2001. The fit and forecast are improved by using macroeconomic exogenous factors such as the gross domestic product per inhabitant (GDP/inhab), the final domestic consumption (FDC) and the gross fixed capital formation (GFCF). The results obtained show that NHGDP (with the above three exogenous factors) provides an adequate fit and medium-term forecast of electricity consumption in Morocco

Modelling of domestic refrigerators' energy consumption under real life conditions in Europe

Energy Technology Data Exchange (ETDEWEB)

Geppert, Jasmin

2011-05-23

In recent decades, energy and resource savings have become increasingly important, not only in the industrial, but also the residential sector. As one of the largest energy users in private homes, domestic refrigerators and freezers were among the first appliances to be targeted for energy efficiency improvements. With the aim of encouraging manufacturers to develop and produce more efficient appliances, the European Energy Label was introduced in the mid-nineties. However, the energy use of refrigerators does not only depend on technical components and features. Especially the using conditions in private homes are of a decisive influence. Thus, the present study has been conducted to test the sensitivity of refrigerators' energy consumption to various usage conditions within realistic ranges, which have been determined by means of two empirical studies. Key information gathered from the experiments were used as a base for the development and validation of a simplified model that allows predicting the energy consumption of refrigerators in use. The practical experiments were performed under controlled laboratory conditions with four different refrigerators with an A{sup +} or A{sup ++} energy efficiency rating (two statically cooled built-in fridge-freezers, one dynamically cooled refrigerator and one statically cooled refrigerator). The investigations revealed that the ambient temperature has the greatest impact on a refrigerator's energy consumption, followed by thermostat setting and heat load by insertion of warm items. The refrigerators' load under static conditions as well as the number of door openings have almost no impact on energy consumption. The modelling methodology follows a first-principle approach adjusted by experimental data. When compared to experimental results, model predictions show a reasonable agreement for the whole range of investigated conditions. (orig.)

2004-01-01

The main message in this paper is that the discussion on sustainable consumption should also incorporate the consumption that occurs in relation to work and, more generally, the relationship between consumption at work and consumption at home. I start by considering how domestic consumption...... is encouraged by work-related factors and continue to consider how consumption activities occur in the workplace, so illustrating that production and consumption are intertwined. The main part of the paper deals in detail with the conceptual distinction between production and consumption. Inspiration is drawn...... from both ecology and economics with focus on some important predecessors for ecological economics. I conclude with reflections on how to proceed with consumption studies to provide the basis for promoting more sustainable life patterns....

Natural gas reserves/total energy consumption: a useful new ratio for addressing global climate change concerns

International Nuclear Information System (INIS)

Siddiqi, T.A.

2002-01-01

Energy analysts have used the reserves/production ratios for oil and natural gas for decades as indicators of the ability of countries to maintain or increase their production of those fuels. The global community is now faced with the challenge of reducing carbon dioxide emissions from a variety of sources, with the energy sector being the largest contributor to the anthropogenic emissions of greenhouse gases. Natural gas has emerged as a highly desirable fuel, since it produces lower emissions of carbon dioxide than coal or oil for equivalent amounts of energy supplied. The ratio of a country's proven natural gas reserves to its total energy consumption is a good indicator of its ability to improve its air quality situation or address greenhouse gas reduction targets from domestic natural gas sources. This paper provides the ratio for several countries at different stages of development, and discusses some of the implications. In countries where exploration for natural gas has been limited, the estimated resources in place may sometimes be a more useful indicator than proven reserves, and could be used instead. (author)

The Characteristic and Impact of the Change in Consumption of Roughage for China in Recent Years

Food security is of great importance to national economy and the people's livelihood, and the method to ensure which has always been an issue paid close attention to by both Chinese government and people. Among all the fodders, the change in consumption of roughage is highly relative to the amount and growing status of the livestock including pig, goat, cattle and dairy cattle which makes it a vital factor of food security and worth studying. Apart from reading considerable amount of both domestic and international materials and conducting data selection, this research focuses on the change in roughage consumption of domestic livestock industry and the impact of intensive farming raise on the consumption. And we came up with two conclusions. First, in recent years, roughage consumption has been experiencing a dramatic decrease caused mainly by the decrease of roughage consumption of pigs. Second, with the increasing trend of pig intensive farming, its main fodder has transformed from roughage to concentrated feed and inevitably leads to roughage as well as total fodder consumption decline and concentrated feed consumption increase. And the profit of intensive farming raise outweighs that of extensive farming and small-scale farming. The study firstly calculates the roughage consumption of domestic livestock industry. It also states the important role roughage plays in the development of livestock industry from the perspective of food security.

2016-01-01

The aim of this study is to model electric power consumption during a period of economic crisis, characterised by declining gross domestic product. A novel aspect of this study is its use of a Gamma-type diffusion process for short and medium-term forecasting – other techniques that have been used to describe such consumption patterns are not valid in this situation. In this study, we consider a new extension of the stochastic Gamma diffusion process by introducing time functions (exogenous factors) that affect its trend. This extension is defined in terms of Kolmogorov backward and forward equations. After obtaining the transition probability density function and the moments (specifically, the trend function), the inference on the process parameters is obtained by discrete sampling of the sample paths. Finally, this stochastic process is applied to model total net electricity consumption in Spain, when affected by the following set of exogenous factors: Gross Domestic Product (GDP), Gross Fixed Capital Formation (GFCF) and Final Domestic Consumption (FDC). - Highlights: • The aim is modelling and predicting electricity consumption in Spain. • We propose a Gamma-type diffusion process for short and medium-term forecasting. • We compared the fit using diffusion processes with different exogenous factors.

Fuelwood consumption in Newfoundland

Energy Technology Data Exchange (ETDEWEB)

1979-01-01

Fuelwood consumption increased in Newfoundland in the 1970's, but although cutting permits were issued for Crown land, most forests were privately leased and no overall figures were available on the annual cut for domestic use. A personal interview telephone survey was therefore implemented in which householders were questioned on how much wood they burned, when they started burning wood, type of stove and wood used, expected consumption in 1978-79, other sources of heat, employment, and distance travelled to obtain wood. Survey methods and results obtained are presented. Woodburning households increased from about 22,000 before 1973 to about 32,000 in 1977-78 and a further increase to about 39,500 was expected in 1978-79. In 1977-78, 462,571 stacked cubic metres of roundwood were burned on the island. Softwood comprised 69% of this total.

Full Text Available In this study we investigated the relation between energy consumption and growth of total factor productivity (TFP of agriculture in Iran from 1974 to 2012 using Solow residual method. The results from estimated aggregate Cobb–Douglas production function showed that one percent change in the value of labor, capital and energy will lead to 4.07, 0.09 and 0.49 percent change in agriculture value added, respectively. Also in a long term, based on the Johansen cointegration test, there is a negative relation between TFP growth and energy consumption in Iranian agriculture which might be due to cheap and inefficient energy use in this sector. Gradual liberalization of energy price and use of so called green box support policies is recommended.

Domestic hot water (DHW) heating is the second largest energy end use in U.S. buildings, exceeded only by space conditioning. Recirculation systems consisting of a pump and piping loop(s) are commonly used in multifamily buildings to reduce wait time for hot water at faucets; however, constant pumping increases energy consumption by exposing supply and return line piping to continuous heat loss, even during periods when there is no demand for hot water. In this study, ARIES installed and tested two types of recirculation controls in a pair of buildings in order to evaluate their energy savings potential. Demand control, temperature modulation controls, and the simultaneous operation of both were compared to the baseline case of constant recirculation. Additionally, interactive effects between DHW control fuel reductions and space conditioning (heating and cooling) were estimated in order to make more realistic predictions of the payback and financial viability of retrofitting DHW systems with these controls. Results showed that DHW fuel consumption reduced by 7% after implementing the demand control technique, 2% after implementing temperature modulation, and 15% after implementing demand control and temperature modulation techniques simultaneously; recirculation pump runtime was reduced to 14 minutes or less per day. With space heating and cooling interactions included, the estimated annual cost savings were 8%, 1%, and 14% for the respective control techniques. Possible complications in the installation, commissioning and operation of the controls were identified and solutions offered.

Exploring the relationship between energy consumption and GDP: Evidence from Croatia

International Nuclear Information System (INIS)

Borozan, Djula

2013-01-01

The main purpose of this paper is to explore the relationship between total energy consumption and real gross domestic product (GDP) covering the period between 1992 and 2010 in Croatia. The methodology employed in this paper is based on the bivariate vector autoregression (VAR) and Granger causality tests. Moreover, the impulse response function and variance decomposition analysis are employed to trace the dynamic response paths of shocks to the system. The empirical analysis shows that, when it is allowed for any deterministic component in the data, total energy consumption and real GDP are not co-integrated in the period observed. Furthermore, there is a unidirectional causality running from total energy consumption to GDP, and an impulse response to GDP caused by energy consumption, being mainly embodied in the first years. The results indicate that total energy consumption is an important component determining economic growth in Croatia and that energy conservation policy should be formulated and implemented wisely. This paper also tests the causality between real GDP and consumption of the five energy variables by using the bivariate VAR. The main implication of these tests is that individual energy forms matter when it comes to energy policy formulation. - Highlights: • There is a unidirectional causality running from energy consumption to real GDP in Croatia. • There is an impulse response to real GDP caused by energy consumption, being mainly embodied in the first years. • Energy consumption is an important component determining economic growth. • Individual energy forms matter when it comes to energy policy formulation

The influence of economic and demographic variables on the annual electricity consumption in Italy has been investigated with the intention to develop a long-term consumption forecasting model. The time period considered for the historical data is from 1970 to 2007. Different regression models were developed, using historical electricity consumption, gross domestic product (GDP), gross domestic product per capita (GDP per capita) and population. A first part of the paper considers the estimation of GDP, price and GDP per capita elasticities of domestic and non-domestic electricity consumption. The domestic and non-domestic short run price elasticities are found to be both approximately equal to -0.06, while long run elasticities are equal to -0.24 and -0.09, respectively. On the contrary, the elasticities of GDP and GDP per capita present higher values. In the second part of the paper, different regression models, based on co-integrated or stationary data, are presented. Different statistical tests are employed to check the validity of the proposed models. A comparison with national forecasts, based on complex econometric models, such as Markal-Time, was performed, showing that the developed regressions are congruent with the official projections, with deviations of {+-}1% for the best case and {+-}11% for the worst. These deviations are to be considered acceptable in relation to the time span taken into account. (author)

Full Text Available The European Mediterranean coastline has experienced major tourism-related urbanization since 1960. This is a dynamic that has led to increased spending on water consumption for urban and tourism-related uses. The objective of this paper is to define and to analyze how domestic water consumption in the city of Alicante evolved between 2000 and 2013. Real billing figures for individual households were analyzed according to the type of housing and the income level of the occupants. The conclusions drawn show that consumption fell over the period studied, and that there are different patterns in water expenditure depending on the type of housing and the inhabitants.

A high sugar intake is a subject of scientific debate due to the suggested health implications and recent free sugar recommendations by the WHO. The objective was to complete a food composition table for added and free sugars, to estimate the intake of total sugars, free sugars, and added sugars, adherence to sugar guidelines and overall diet quality in Dutch children and adults. In all, 3817 men and women (7-69 years) from the Dutch National Food Consumption Survey 2007-2010 were studied. Added and free sugar content of products was assigned by food composition tables and using labelling and product information. Diet was assessed with two 24-h recalls. Diet quality was studied in adults with the Dutch Healthy Diet-index. Total sugar intake was 22% Total Energy (%TE), free sugars intake 14 %TE, and added sugar intake 12 %TE. Sugar consumption was higher in children than adults. Main food sources of sugars were sweets and candy, non-alcoholic beverages, dairy, and cake and cookies. Prevalence free sugar intake diet quality was similar comparing adults adherent and non-adherent to the sugar guidelines, although adherent adults had a higher intake of dietary fiber and vegetables. Adherence to the WHO free sugar guidelines of sugar guidelines was not strongly associated with higher diet quality in adults.

Coffee consumption has been associated with reduced risk for death in prospective cohort studies; however, data in nonwhites are sparse. To examine the association of coffee consumption with risk for total and cause-specific death. The MEC (Multiethnic Cohort), a prospective population-based cohort study established between 1993 and 1996. Hawaii and Los Angeles, California. 185 855 African Americans, Native Hawaiians, Japanese Americans, Latinos, and whites aged 45 to 75 years at recruitment. Outcomes were total and cause-specific mortality between 1993 and 2012. Coffee intake was assessed at baseline by means of a validated food-frequency questionnaire. 58 397 participants died during 3 195 484 person-years of follow-up (average follow-up, 16.2 years). Compared with drinking no coffee, coffee consumption was associated with lower total mortality after adjustment for smoking and other potential confounders (1 cup per day: hazard ratio [HR], 0.88 [95% CI, 0.85 to 0.91]; 2 to 3 cups per day: HR, 0.82 [CI, 0.79 to 0.86]; ≥4 cups per day: HR, 0.82 [CI, 0.78 to 0.87]; P for trend coffee. Significant inverse associations were observed in 4 ethnic groups; the association in Native Hawaiians did not reach statistical significance. Inverse associations were also seen in never-smokers, younger participants (coffee was associated with lower risk for death in African Americans, Japanese Americans, Latinos, and whites.

2006-01-01

According to preliminar calculations by the Arbeitsgemeinschaft Energiebilanzen (Working Party on Energy Balances, AGEB), the consumption of an aggregate 486 million TCE of primary energy resources in Germany last year was 1.3% below the level of the year before. Energy consumption was influenced by both the high level of prices and the development of the economy. Hardly any influence was attributable to the level of temperatures, which was largely unchanged compared to the figure of the year before. Oil consumption in 2005 in Germany dropped by nearly 2% to 174.8 million TCE. On the whole, oil with its 36% share in the energy balance remained by far the most important energy resource in Germany. Natural gas consumption of 110.4 million TCE was at the level of the year before. Its share in the primary energy balance rose slightly to 22.7%. Hard coal, because of lower use in power plants and the decline in iron making, showed a 4.6% drop in consumption to 62.8 million TCE. In this way, hard coal contributed 13% to total energy consumption. Lignite consumption dropped by 3.2% to 54.4 million TCE as a result of lower deliveries to power plants. Its 11.2% share in the total consumption of primary energy continued to make lignite the most important domestic energy resource. More than 90% of the lignite produced is used for electricity generation. The contribution to primary energy consumption of nuclear power dropped by more than 2% to 60.7 million TCE. Hydroelectric plants and wind power plants increased their contribution by 3.6%. The contribution to primary energy consumption made by all renewable energy resources rose to 4.6%. AGEB evaluates statistics of all areas of the power economy on the basis of standard criteria in order to combine these data in a comprehensive picture. Since 1994, the energy balances for Germany have been compiled by DIW on behalf of AGEB. (orig.)

Energy consumption in office buildings. Trends and drivers; Energibruk i kontorbygg. Trender og drivere

Energy Technology Data Exchange (ETDEWEB)

Langseth, Benedicte

2013-02-01

This report focuses on the energy usage of Norwegian office buildings. Historic data on the subject is limited, so qualitative input is gathered through interviews with property owners and contractors for energy solutions. We have looked at what affects the total area of office buildings in Norway, and realized that it more or less follows the inland gross domestic product. The report also includes cross-sectional analyses from various data sources to find what affects the specific energy usage of office buildings. The actual measured consumption deviates from estimated consumption, especially in newer buildings and especially within ventilation and cooling. Additionally, a model has been developed for projective purposes. It is well suited to test the effect of various input parameters and assumptions on the total area of office buildings and their energy consumption. Though as of yet the quality of data is not good enough to make a profound and credible estimate of total energy usage.(eb)

Practical versus theoretical domestic energy consumption for space heating

International Nuclear Information System (INIS)

Audenaert, A.; Briffaerts, K.; Engels, L.

2011-01-01

Methods to calculate the theoretical energy consumption consider several things: the number of degree days per year that need to be compensated by heating, the characteristics of the dwelling, the number of occupants and the characteristics of the installation for space heating and sanitary hot water. However, these methods do not take into account consumer behaviour, which may affect the actual consumption. The theoretical calculation methods are based on assumptions and use a number of standardized parameters. The difference between the actual and the theoretical energy consumption, and the impact of the residents' behaviour on energy consumption, is analysed by means of a literature study and a practical research. An energy advice procedure (EAP) audit is executed in five dwellings, as well as a survey regarding the energy related behaviour of the households. The theoretically calculated consumption is compared with the billed actual energy consumption of the families. The results show some problems with the current procedure and give some options to improve it. Some research needs are identified to gain more insights in the influence of different behavioural factors on the actual energy use for heating. - Highlights: → The energy advice procedure (EAP) calculates the energy use for heating in dwellings. → Calculations are compared with the real energy use for 5 dwellings. → A survey on the occupants' behaviour is used to interpret the observed differences. → Default values used in the EAP can be very different from the observed behaviour.

Toxoplasma gondii is a prevalent protozoan parasite worldwide. Human toxoplasmosis is responsible for considerable morbidity and mortality in the United States, and meat products have been identified as an important source of T. gondii infections in humans. The goal of this study was to develop a farm-to-table quantitative microbial risk assessment model to predict the public health burden in the United States associated with consumption of U.S. domestically produced lamb. T. gondii prevalence in market lambs was pooled from the 2011 National Animal Health Monitoring System survey, and the concentration of the infectious life stage (bradyzoites) was calculated in the developed model. A log-linear regression and an exponential doseresponse model were used to model the reduction of T. gondii during home cooking and to predict the probability of infection, respectively. The mean probability of infection per serving of lamb was estimated to be 1.5 cases per 100,000 servings, corresponding to ∼6,300 new infections per year in the U.S. Based on the sensitivity analysis, we identified cooking as the most effective method to influence human health risk. This study provided a quantitative microbial risk assessment framework for T. gondii infection through consumption of lamb and quantified the infection risk and public health burden associated with lamb consumption.

Flexible demand in the GB domestic electricity sector in 2030

International Nuclear Information System (INIS)

Drysdale, Brian; Wu, Jianzhong; Jenkins, Nick

2015-01-01

Highlights: • Annual domestic demand by category and daily flexible load profiles are shown to 2030. • Valuable flexible demand requires loads to be identifiable, accessible, and useful. • The extent of flexible demand varies significantly on a diurnal and seasonal basis. • Barriers to accessing domestic demand include multiple low value loads and apathy. • Existing market structure a barrier to fully rewarding individual load flexibility. - Abstract: In order to meet greenhouse gas emissions targets the Great Britain (GB) future electricity supply will include a higher fraction of non-dispatchable generation, increasing opportunities for demand side management to maintain a supply/demand balance. This paper examines the extent of flexible domestic demand (FDD) in GB, its usefulness in system balancing and appropriate incentives to encourage consumers to participate. FDD, classified as electric space and water heating (ESWH), and cold and wet appliances, amounts to 59 TW h in 2012 (113 TW h total domestic demand) and is calculated to increase to 67 TW h in 2030. Summer and winter daily load profiles for flexible loads show significant seasonal and diurnal variations in the total flexible load and between load categories. Low levels of reflective consumer engagement with electricity consumption and a resistance to automation present barriers to effective access to FDD. A value of £1.97/household/year has been calculated for cold appliance loads used for frequency response in 2030, using 2013 market rates. The introduction of smart meters in GB by 2020 will allow access to FDD for system balancing. The low commercial value of individual domestic loads increases the attractiveness of non-financial incentives to fully exploit FDD. It was shown that appliance loads have different characteristics which can contribute to an efficient power system in different ways

How to reduce risk of climate change: Domestic hot water production methanization and programmed timing of heaters

International Nuclear Information System (INIS)

Silvestrini, G.

1992-01-01

This paper first identifies a significant and deleterious trend, in terms of poor energy efficiency and high carbon dioxide emissions, towards the increased use of electric water heaters for sanitary hot water production in single family units. It then points out how the use of wall mounted methane fired boilers can result in overall energy savings (overall electric power consumption for domestic hot water production is estimated to represent one- quarter of Italy's total domestic power demand), as well as air pollution abatement. The feasibility of other methods of energy conservation and pollution abatement in domestic water heating are also examined. These include the use of solar hot water heaters, computerized timers which allow users to program the operation of their heating plants, and the adoption by residential communities of methane fuelled district heating plants

2018-06-01

This study aimed to compare sugar intake in Australian children with current guidelines and determine if total sugar consumption as a percentage of energy (sugar %E) exacerbates the relationship between sleep and behaviour. A sample of 287 children aged 8-12 years (boys 48.8%, age: 10.7 ± 1.3 years), and their parents/guardians completed a battery of questionnaires. Children completed a food frequency questionnaire, and parents completed demographic, sleep, and behaviour questionnaires. Average sugar intake was 134.9 ± 71.7 g per day (sugar %E 26.0 ± 7.0%), and only 55 (19%) participants did not exceed the recommended sugar intake limit. Correlations and logistical regressions indicated that sugar %E was not associated with sleep or behavioural domains (r range = -0.07-0.08; p range = .173-.979) nor contributed to the prediction of sleep behaviour problems (p range = .16-.80). Whilst a high proportion of children consumed above the recommended amount of daily total sugar, total sugar consumption was not related to behavioural or sleep problems, nor affected the relationship between these variables.

In England, housing accounts for some 30% of total fuel consumption and a similar proportion of energy-related carbon dioxide (CO/sub 2/) emission. A study has been conducted to analyse the effect of the legislations and UK thermal building regulations on national energy consumption in housing. This research paper presents data on the percentage of dwelling stock, the energy consumption, energy cost and carbon dioxide (CO/sub 2/) emission in different types of dwellings, which comply different building regulations from 1965 to 1995. It was found that. 66% of the dwelling stock, which comply the building Regulations before 1965, consumes 73% of total energy used in housing. This dwelling stock is also responsible for 75% of carbon dioxide (CO/sub 2/) emission. Whereas currently only 4% of the dwelling stock complies the latest building regulations 1995 which consume 2 % of energy and produce a similar percentage of carbon dioxide (CO/sub 2/) emission in housing. Since the large portion of the dwelling stock is comprised of old dwellings, therefore the greatest potential for energy conservation measures can be found in improving these dwellings instead of constructing new dwellings.

A high sugar intake is a subject of scientific debate due to the suggested health implications and recent free sugar recommendations by the WHO. The objective was to complete a food composition table for added and free sugars, to estimate the intake of total sugars, free sugars, and added sugars, adherence to sugar guidelines and overall diet quality in Dutch children and adults. In all, 3817 men and women (7–69 years) from the Dutch National Food Consumption Survey 2007–2010 were studied. Added and free sugar content of products was assigned by food composition tables and using labelling and product information. Diet was assessed with two 24-h recalls. Diet quality was studied in adults with the Dutch Healthy Diet-index. Total sugar intake was 22% Total Energy (%TE), free sugars intake 14 %TE, and added sugar intake 12 %TE. Sugar consumption was higher in children than adults. Main food sources of sugars were sweets and candy, non-alcoholic beverages, dairy, and cake and cookies. Prevalence free sugar intake diet quality was similar comparing adults adherent and non-adherent to the sugar guidelines, although adherent adults had a higher intake of dietary fiber and vegetables. Adherence to the WHO free sugar guidelines of sugar guidelines was not strongly associated with higher diet quality in adults. PMID:26828518

The growth of energy consumption and prices in the USA, West Germany, and the UK, 1950 to 1980

Science.gov (United States)

Doblin, C. P.

1982-05-01

The relationship between energy price and consumption was studied, especially reactions to oil price rises in the 1970's. Industrial, domestic, and road transportation energy consumption were examined. Until 1973, consumption rose steadily, while the inflation-adjusted price dropped. Immediate reaction to the two large price rises was a drop in consumption, but overall consumption continued to grow when the growth in total energy consumption was reversed. This change is due to adverse business conditions, displacement of coal by oil, oil by gas, and mineral fuels by electricity in given sectors, switches to less energy intensive activities, a change in the mix of gross national products, and weather conditions, as well as by price rises. Energy conservation measures had little impact.

This paper investigates the causal relationship between energy consumption and economic productivity in Malaysia at both aggregated and disaggregated levels. The investigation utilises total and sectoral (industrial and manufacturing) productivity growth during the 1971–2012 period using the modified Granger causality test proposed by Toda and Yamamoto [1] within a multivariate framework. The economy of Malaysia was found to be energy dependent at aggregated and disaggregated levels of national and sectoral economic growth. However, at disaggregate level, inefficient energy use is particularly identified with electricity and coal consumption patterns and their Granger caused negative effects upon GDP (Gross Domestic Product) and manufacturing growth. These findings suggest that policies should focus more on improving energy efficiency and energy saving. Furthermore, since emissions are found to have a close relationship to economic output at national and sectoral levels green technologies are of a highest necessity. - Highlights: • At aggregate level, energy consumption significantly influences GDP (Gross Domestic Product). • At disaggregate level, electricity & coal consumption does not help output growth. • Mineral and waste are found to positively Granger cause GDP. • The results reveal strong interactions between emissions and economic growth

The 1999 MWV petroleum consumption forecast: Petroleum still in the lead in the German energy market

1999-01-01

Petroleum consumption in Germany has been stagnant over the last few years. Since in 1998 the decline in light heating oil sales was balanced out by an increase in fuel consumption and petroleum sales to the petrochemical industry, total domestic supplies of petroleum products amounted to 127.4 million tonnes and thus remained at last year's level. According to the latest forecast of the Mineraloelwirtschaftsverband e.V., extending to the year 2010, stagnation will continue for some years, but petroleum consumption is expected to then take a clear downward trend and fall off by 11 million tonnes (or 9%) until 2010.

The purpose of this research is to examine the amount and the structure of direct and indirect energy consumption in connection with leisure occupations at the beginning of the 1990s and to estimate energy saving possibilities connected to these activities. The study deals with 22 activities: going to restaurants, coffee shops, cafeterias, and pubs, going to the theatre, going to the opera, going to ice-hockey matches, going to horse races, going to automobile races, domestic travel, summer cottage use, boating, jogging, cross-country skiing, downhill skiing, ski jumping, ice hockey and other ice sports, swimming in indoor pools, swimming at spas, golf, and car racing. The energy use of individual leisure activities makes up 0,02-1,86 % of Finland`s total annual household energy consumption. Total energy consumption is affected not only by the frequency of an activity but especially by the related need for transportation for an activity. Transportation makes up 20-90 % of the total energy used, and the bulk of this consumption is caused by recreation participants travelling to facilities. The proportion of energy use at the facilities is usually 10-30 %. Recreational equipment require 1-20 %, and activity-related accommodation generally 0-5 % of the total. Activities can be compared to each other on the basis of how much energy is used in one event. By individual choice, consumption related to travel and equipment can be minimized the most. However, individuals have little possibility of influencing the amount of energy used at leisure facilities. (85 refs.)

2016-10-01

Full Text Available Background: The aim of this study was to investigate total water intake (TWI from water, beverages and foods among Italian adults and the elderly. Methods: Data of 2607 adults and the elderly, aged 18–75 years from the last national food consumption survey, INRAN-SCAI 2005-06, were used to evaluate the TWI. The INRAN-SCAI 2005-06 survey was conducted on a representative sample of 3323 individuals aged 0.1 to 97.7 years. A 3-day semi-structured diary was used for participants to record the consumption of all foods, beverages and nutritional supplements. Results: On average, TWI was 1.8 L for men and 1.7 L for women. More than 75% of women and 90% of men did not comply with the European Food Safety Authority (EFSA Adequate Intake. The contribution of beverages to the total energy intake (EI was 6% for the total sample. Water was the most consumed beverage, followed by alcoholic beverages for men and hot beverages for women. Conclusion: According to the present results, adults and elderly Italians do not reach the adequate intake for water as suggested by the EFSA and by the national reference level of nutrient and energy intake. Data on water consumption should also be analyzed in single socio-demographic groups in order to identify sub-groups of the population that need more attention and to plan more targeted interventions.

Constantin ANGHELACHE

2011-09-01

Full Text Available This paper presents the results of the researches performed by the author regarding the evolution of Gross Domestic Product. One of the main aspects of GDP analysis is the correlation with the final consumption, an important macroeconomic indicator. The evolution of the Gross Domestic Product is highly influenced by the evolution of the final consumption. To analyze the correlation, the paper proposes the use of the linear regression model, as one of the most appropriate instruments for such scientific approach. The regression model described in the article uses the GDP as resultant variable and the final consumption as factorial variable.

Two domestic ilmenites and one titaniferous magnetite were prereduced by the United States Department of the Interior, Bureau of Mines, in a batch rotary kiln with coal char to assess the feasibility of this technique in improving melting operations and subsequent electric furnace processing. All three prereduced titaniferous materials were melted satisfactorily in an electric arc furnace to produce iron as a metal suitable for further refining to steel; metallizations ranging from 63 to 83 pct of the iron oxides were achieved. The ilmenites yielded titanium enriched slags that were amenable to further processing by conventional methods. Prereduction decreased electrode consumption during furnace operation and also conserved expensive electrical energy that otherwise must be used to reduce and melt totally the entire titaniferous materials charge.

In the future, buildings will not only act as consumers of energy but as producers as well. For these ''prosumers'', energy production by use of solar panels, photovoltaics and heat pumps etc will be essential. The objective of this project was to find the most optimal combinations of building insulation and use of renewable energy sources in existing buildings in terms of economics and climate impacts. Five houses were analyzed based on different personal load, consumption profiles, solar orientation and proposed building envelope improvements and use of combinations of renewable energy systems. The present report describes how person and consumption profiles used in this project are developed, and which data that form the basis for these profiles. The increasing requirements for energy in the building sector mean that the primary energy consumption ends close to or below zero within the next years. Therefore, the consumption in buildings becomes a relatively larger and larger part of the total energy demand in dwellings. It is important to investigate whether there are seasonal distributions of power and water consumption, because it might give a more exact result and describe the reality better than by using yearly values. First, the personal load determined, and then humidity and consumption of both power and hot water is defined. Second, the hourly profiles are developed based on analyses of seasonal distributions. These profiles also include cold domestic water to see whether there is a correlation between this and hot domestic water. (ln)

Exploring the relationship between urbanization and energy consumption in China using ARDL (autoregressive distributed lag) and FDM (factor decomposition model)

Liu, Yaobin

2009-01-01

The paper develops a function of energy consumption, population growth, economic growth and urbanization process, and provides fresh empirical evidences for urbanization and energy consumption for China over the period 1978-2008 through the use of ARDL testing approach and factor decomposition model. The results of the bounds test show that there is a stable long run relationship amongst total energy consumption, population, GDP (Gross domestic product) and urbanization level when total energy consumption is the dependent variable in China. The results of the causality test with ECM (error correction model) specification, the short run and long run dynamics of the interested variables are tested, indicating that there exists only a unidirectional Granger causality running from urbanization to total energy consumption both in the long run and in the short run. At present, the contribution share which urbanization drags the energy consumption is smaller than that in the past, and the intensity holds a downward trend. Therefore, together with enhancing energy efficiency, accelerating the urbanization process that can cut reliance on resource and energy dependent industries is a fundamental strategy to solve the sustainable development dilemma between energy consumption and urbanization.

Desmet, Matthias; Vermeylen, Kris; Van Herreweghe, Imré; Carlier, Laurence; Soetens, Filiep; Lambrecht, Stijn; Croes, Kathleen; Pottel, Hans; Van de Velde, Marc

The role of a fascia iliaca compartment block (FICB) for postoperative analgesia after total hip arthroplasty (THA) remains questionable. High-dose local anesthetics and a proximal injection site may be essential for successful analgesia. High-dose local anesthetics may pose a risk for local anesthetic systemic toxicity. We hypothesized that a high-dose longitudinal supra-inguinal FICB is safe and decreases postoperative morphine consumption after anterior approach THA. We conducted a prospective, double blind, randomized controlled trial. Patients scheduled for THA were randomized to group FICB (longitudinal supra-inguinal FICB with 40-mL ropivacaine 0.5%) or group C (control, no block). Standard hypothesis tests (t test or Mann-Whitney U test, χ test) were performed to analyze baseline characteristics and outcome parameters. The primary end point of the study was total morphine (mg) consumption at 24 hours postoperatively. Serial total and free ropivacaine serum levels were determined in 10 patients. After obtaining ethical committee approval and written informed consent, 88 patients were included. Mean (SD) morphine consumption at 24 hours postoperatively was reduced in group FICB compared to group C: 10.25 (1.64) mg versus 19.0 (2.4) mg (P = 0.004). Using a mean dose of 2.6-mg/kg ropivacaine (range, 2-3.4 mg/kg), none of the patients had total or free ropivacaine levels above the maximum tolerated serum concentration. We conclude that a high-dose longitudinal supra-inguinal FICB reduces postoperative morphine requirements after anterior approach THA.Clinical Trials Registry: EU Clinical Trials Register. www.clinicaltrialsregister.eu #2014-002122-12.

Sinha, C.S.; Joshi, Veena

1994-01-01

The major efforts and their limitations to formulate rural domestic energy requirements in India are discussed. Results of some of the recent efforts for quantifying biofuel consumption in rural areas are presented. Emphasis is on the recent efforts to collate and analyze results of energy consumption survey of 638 villages covering over 39,000 households. These are used to estimate biofuel use for different agro-climatic regions in India by estimating consumption at the district level in the rural domestic sector. The results are aggregated at the state level and they are compared with other estimates for India. The range of consumption aggregated at the national level is found to vary widely (93-252 million tonnes/yr of firewood, 54-107 million tonnes/yr of animal waste and 36-99 million tonnes/yr of agricultural residues). Reasons for the wide disparity in the results is briefly discussed. (author)

Gross Domestic Product (GDP) is an indicator of economic growth in a region. GDP is a panel data, which consists of cross-section and time series data. Meanwhile, panel regression is a tool which can be utilised to analyse panel data. There are three models in panel regression, namely Common Effect Model (CEM), Fixed Effect Model (FEM) and Random Effect Model (REM). The models will be chosen based on results of Chow Test, Hausman Test and Lagrange Multiplier Test. This research analyses palm oil about production, export, and government consumption to five district GDP are in West Kalimantan, namely Sanggau, Sintang, Sambas, Ketapang and Bengkayang by panel regression. Based on the results of analyses, it concluded that REM, which adjusted-determination-coefficient is 0,823, is the best model in this case. Also, according to the result, only Export and Government Consumption that influence GDP of the districts.

The 1988 coal outlook: steadily rising consumption

Energy Technology Data Exchange (ETDEWEB)

Soras, C.G.; Stodden, J.R.

1987-12-01

Total coal use - domestic and foreign - will reach 910 million tons in 1988, an expansion of 1.3% from an estimated 898 million tons in 1987. The overall rise in consumption will add to inventory needs. Moreover, lower interest rates cut effective carrying costs and further encourage the holding of coal stocks by users. The results will be a gain in inventories of 3.5 tons by the end of 1988. As a result of all these factors, coal production is anticipated to rise by 11.6 million tons, or 1.2%, which projects firm markets in a time of relatively soft economic conditions in the USA. 2 tabs.

Full Text Available A high sugar intake is a subject of scientific debate due to the suggested health implications and recent free sugar recommendations by the WHO. The objective was to complete a food composition table for added and free sugars, to estimate the intake of total sugars, free sugars, and added sugars, adherence to sugar guidelines and overall diet quality in Dutch children and adults. In all, 3817 men and women (7–69 years from the Dutch National Food Consumption Survey 2007–2010 were studied. Added and free sugar content of products was assigned by food composition tables and using labelling and product information. Diet was assessed with two 24-h recalls. Diet quality was studied in adults with the Dutch Healthy Diet-index. Total sugar intake was 22% Total Energy (%TE, free sugars intake 14 %TE, and added sugar intake 12 %TE. Sugar consumption was higher in children than adults. Main food sources of sugars were sweets and candy, non-alcoholic beverages, dairy, and cake and cookies. Prevalence free sugar intake <10 %TE was 5% in boys and girls (7–18 years, 29% in women, and 33% in men. Overall diet quality was similar comparing adults adherent and non-adherent to the sugar guidelines, although adherent adults had a higher intake of dietary fiber and vegetables. Adherence to the WHO free sugar guidelines of <5 %TE and <10 %TE was generally low in the Netherlands, particularly in children. Adherence to the added and free sugar guidelines was not strongly associated with higher diet quality in adults.

Impact of insulation and consumer behavior on natural gas consumption

Energy Technology Data Exchange (ETDEWEB)

van Mastrigt, P.

1983-09-01

The influence of insulation measures and certain changes in behavioral patterns on gas consumption for home heating has been examined, both on an annual basis and on the maximum day and at the maximum hour. By means of good insulation (cavity wall insulation and double glazing on the ground floor) annual gas consumption can be brought down by 28-35%, depending on the type of dwelling, as compared with moderate insulation. Maximum day consumption will go down by 26-33% and maximum hour consumption by no more than 20-28%. Further insulation, to current Danish standards, would enable savings of up to 72% of annual consumption, 64-66% of maximum day consumption and 52-55% of maximum hour consumption. By further night reduction from 14.5 degrees C to 12 degrees C 2% of the annual consumption can be saved in moderately insulated dwellings. It also leads, however, to an increase in maximum hour consumption by some 11%. In heavily insulated dwellings further night reduction does not yield any additional savings on the annual consumption. By lowering the thermostat setting by 2 degrees C in the daytime annual consumption in a moderately insulated dwelling can be cut by 9%. With increasing insulation level the savings will get higher, up to 11% in heavily insulated dwellings. Drawing the curtains during the evening and night may yield savings of 4-6% depending on the ratio of glass surface to total outer wall surface. These savings will be lower as the insulation level increases. The results of the study have been converted to the overall domestic natural gas consumption in the Netherlands. In 1985 the annual consumption will be 7% lower than in 1978 as a result of insulation measures and changes in consumer behavior, even at a rise in the total number of connections. Maximum day consumption will be 5% lower and maximum hour consumption will be virtually the same. This trend became already manifest during the 1978-1982 period.

Analysis of effecting factors on domestic refrigerators’ energy consumption in use

International Nuclear Information System (INIS)

Geppert, Jasmin; Stamminger, Rainer

2013-01-01

Highlights: • Energy consumption of refrigerators is highly sensitive to operating conditions. • Ambient temperature has the highest impact on energy consumption of refrigerator. • There is a quadratic relationship between ambient temperature and energy use. • Compartment temperature and additional heat load have a lower impact on energy use. • Under moderate conditions, measured energy use closely match Energy Label values. - Abstract: In order to determine the sensitiveness of refrigerators’ energy consumption on various operational factors reflecting real life conditions, four different refrigerators were tested in laboratory using Box–Behnken design with three variables (ambient temperature, thermostat setting position and additional heat load by storing warm food) at three different levels. The investigations show that the energy consumption of refrigerators is highly sensitive to actual operational conditions. Daily energy consumption of one and the same appliance may vary between a few watt-hours and 2000 Wh and even more, dependent on the respective operational factors. Analysis of variance (ANOVA) reveals that ambient temperature is the most influential factor on the energy consumption of a refrigerator. Energy use is also affected, to a minor degree, by internal compartment temperature and additional heat load. Test results are presented and energy consumption data are compared with values shown on the European Energy Label. Results are discussed also with regard to the question as to whether or not the Energy Label and the associated test standard are appropriate to project actual energy consumption in use

International oil shocks and household consumption in China

2014-01-01

We investigate the impacts that oil price shocks have on residential consumption in China. While it is well understood that oil prices affect consumption in a multitude of ways, the timing and directness of these effects on specific consumption categories is not clear. We demonstrate that the most immediate and direct effect passes through transportation consumption, as might be expected. But we also show that significant effects pass through consumption in other sectors—including “food and clothes”, “medical expenditure”, and other general “living expenditure”—with less immediacy. Given the results, particularly observed asymmetries with respect to rises and falls in international oil prices, we discuss some implications for future adjustments to domestic price policies, in particular the case for removal of domestic price regulation. - Highlights: • We study the impact of oil price shocks on residential consumption in China. • The most immediate effect passes through expenditure on transportation. • Effects also appear for health, education and food and clothing expenditure. • Existing price regulation offers no great benefit. • We argue that a compelling case for removing current price regulation exists

Highlights: • Innovative method linking appliance usage and energy use with domestic activities. • Inferring the energy and time use profile of activities based on smart meter data. • Standardised metrics quantifying energy intensity + temporal routines of activities. • Insights from analysing electricity consumption through the lens of activities. - Abstract: Household electricity consumption can be broken down to appliance end-use through a variety of methods such as modelling, sub-metering, load disaggregation or non-intrusive appliance load monitoring (NILM). We advance and complement this important field of energy research through an innovative methodology that characterises the energy consumption of domestic life by making the linkages between appliance end-use and activities through an ontology built from qualitative data about the household and NILM data. We use activities as a descriptive term for the common ways households spend their time at home. These activities, such as cooking or laundering, are meaningful to households’ own lived experience. Thus, besides strictly technical algorithmic approaches for processing quantitative smart meter data, we also draw on social science time use approaches and interview and ethnography data. Our method disaggregates a households total electricity load down to appliance level and provides the start time, duration, and total electricity consumption for each occurrence of appliance usage. We then make inferences about activities occurring in the home by combining these disaggregated data with an ontology that formally specifies the relationships between electricity-using appliances and activities. We also propose two novel standardised metrics to enable easy quantifiable comparison within and across households of the energy intensity and routine of activities of interest. Finally, we demonstrate our results over a sample of ten households with an in-depth analysis of which activities can be inferred with

Illicit cigarette consumption and government revenue loss in Indonesia.

Science.gov (United States)

Ahsan, Abdillah; Wiyono, Nur Hadi; Setyonaluri, Diahhadi; Denniston, Ryan; So, Anthony D

2014-11-19

Illicit cigarettes comprise more than 11% of tobacco consumption and 17% of consumption in low- and middle-income countries. Illicit cigarettes, defined as those that evade taxes, lower consumer prices, threaten national tobacco control efforts, and reduce excise tax collection. This paper measures the magnitude of illicit cigarette consumption within Indonesia using two methods: the discrepancies between legal cigarette sales and domestic consumption estimated from surveys, and discrepancies between imports recorded by Indonesia and exports recorded by trade partners. Smuggling plays a minor role in the availability of illicit cigarettes because Indonesians predominantly consume kreteks, which are primarily manufactured in Indonesia. Looking at the period from 1995 to 2013, illicit cigarettes first emerged in 2004. When no respondent under-reporting is assumed, illicit consumption makes up 17% of the domestic market in 2004, 9% in 2007, 11% in 2011, and 8% in 2013. Discrepancies in the trade data indicate that Indonesia was a recipient of smuggled cigarettes for each year between 1995 and 2012. The value of this illicit trade ranges from less than $1 million to nearly $50 million annually. Singapore, China, and Vietnam together accounted for nearly two-thirds of trade discrepancies over the period. Tax losses due to illicit consumption amount to between Rp 4.1 and 9.3 trillion rupiah, 4% to 13% of tobacco excise revenue, in 2011 and 2013. Due to the predominance of kretek consumption in Indonesia and Indonesia's status as the predominant producer of kreteks, illicit domestic production is likely the most important source for illicit cigarettes, and initiatives targeted to combat this illicit production carry the promise of the greatest potential impact.

Linear and nonlinear causality between sectoral electricity consumption and economic growth: Evidence from Taiwan

International Nuclear Information System (INIS)

Yang, Cheng-Lang; Lin, Hung-Pin; Chang, Chih-Heng

2010-01-01

This study investigates the linear and nonlinear causality between the total electricity consumption (TEC) and real gross domestic production (RGDP). Unlike previous literature, we solve the undetermined relation between RGDP and electricity consumption by classifying TEC into industrial sector consumption (ISC) and residential sector consumption (RSC) as well as investigating how TEC, ISC, and RSC influence Taiwan's RGDP. By using the Granger's linear causality test, it is shown that (i) there is a bidirectional causality among TEC, ISC, and RGDP, but a neutrality between RSC and RGDP with regard to the linear causality and (ii) there is still a bidirectional causality between TEC and RGDP, but a unidirectional causality between RSC and RGDP with regard to the nonlinear causality. On the basis of (i) and (ii), we suggest that the electricity policy formulators loosen the restriction on ISC and limit RSC in order to achieve the goal of economic growth.

Domestication and Genetics of Papaya: A Review

Directory of Open Access Journals (Sweden)

Mariana Chávez-Pesqueira

2017-12-01

Full Text Available A wealth of plant species used by humans for different purposes, but mainly as food, originated and domesticated in the Mesoamerican region. Papaya (Carica papaya is the third most cultivated tropical crop worldwide, and it has been hypothesized that Mesoamerica is the most likely center of its origin and domestication. In support of it, many wild populations of papaya occur throughout Mesoamerica and hence represent the gene pool of genetic variability for further evolution and future crop management. Despite its importance, a dearth of information exists regarding the status of wild populations of papaya, as compared to the extent of knowledge, and interest, on domesticated varieties. We review the evidence on the extant wild populations of papaya, as well as its origin and distribution. Also, we synthetize what is known on the domestication history of the species, including the domestication syndrome that distinguishes wild and domesticated papayas. Moreover, we make an account of the use of genetic markers to assess genetic diversity of wild and domesticated papaya, and discuss the importance of papaya as the first species with a transgenic cultivar to be released for human consumption, and one that has its complete genome sequenced. Evidence from different disciplines strongly suggest that papaya originated and was domesticated in Mesoamerica, and that wild populations in the region possess, still, high genetic diversity compared to the domesticated papaya. Finally, we outline papaya as an excellent model species for genomic studies that will help gain insight into the domestication process and improvement of papaya and other tropical crops.

Highlights: • Energy saving of using nanorefrigerant except of normal refrigerant in domestic refrigerator is investigated in Malaysia. • Using nanorefrigerant cause to reduce energy consumption of domestic refrigerator. • The maximum energy saving would be happen in case of using 0.1% TiO 2 –mineral oil–R134a nanorefrigerant. • Emission reduction is an environmental effect of using nanorefrigerant. - Abstract: The electricity demand in the residential sector has increased rapidly in recent years in Malaysia. This is mainly due to lifestyle improvement; and is also associated with the increase in the number of domestic refrigerators in this tropical country. This paper investigates the effect of using nanorefrigerant on energy saving in domestic refrigerators and emission reduction of greenhouse gases as an environmental viewpoint. The combination of R-134a refrigerant with TiO 2 and Al 2 O 3 nanoparticles with different mass fractions was scrutinized as a new refrigerant. It has been found that the energy saving using nanorefrigerant (0.1% TiO 2 nanoparticle/Mineral Oil) would be greater than normal refrigerant, with 10,863 MW h reduction in energy consumption by the year 2030. In this regard, this technology will be environmentally friendly by decreasing greenhouse emission, especially in terms of carbon dioxide. Thus, nanorefrigerant can help to increase the performance of domestic refrigerators and reduce energy consumption. Favorable effect on emission reduction and economic justification were concluded

Differences in activity concentrations and doses between domestic and commercial food production in England and Wales. Implications for nuclear emergency response

In the event of an accidental release of radionuclides into the environment, MAFF has a statutory responsibility to ensure that a wholesome and safe food supply is maintained to the population of England. MAFF also provides scientific advice on contamination of food by radioactivity to the Welsh Assembly and the Scottish Executive. This responsibility will apply whatever the source of radioactive contamination. Where foods are produced domestically by individuals, i.e. in private gardens and allotments, MAFF has no statutory powers to prevent their harvest or consumption. MAFF must therefore rely solely upon the provision of appropriate advice to protect those domestic producers potentially at risk. Advice which has been issued to such individuals and households during past nuclear emergency exercises has been based on assessments carried out for commercially produced foods. Under contract to MAFF, NRPB has undertaken a desk-top study to review the adequacy of the current MAFF emergency procedures for protecting consumers of foods produced domestically. In particular, the study has examined the validity of basing advice for domestic consumers on commercial food production and consumption, rather than by explicitly considering the domestic situation. As part of the study, reviews have been carried out of the level and types of domestic food production and consumption in the UK. In addition, comparisons have been made between agricultural practices in commercial and domestic situations. The data from these reviews have subsequently been used to compare the doses received by individuals from consuming contaminated foods from commercial and domestic sources. The study has concluded that, in general, the current MAFF emergency procedures for protecting the domestic consumer are adequate. In the event of an accident occurring some factors may need more consideration, however. These include differences in growing periods and harvesting dates between commercial and

This paper presents an experimental investigation on a NERC (novel ejector enhanced refrigeration cycle) applied in the domestic refrigerator-freezer (BCD-249). Experimental studies were conducted to validate the NERC system feasibility in a practical NERC based refrigerator-freezer prototype. The system performances of energy consumption, ejector pressure lift ratio and compressor power were compared under different combinations of system configuration parameters. The results showed that the NERC system could effectively reduce the thermodynamic losses in the throttle processing. The minimum energy consumption of 0.520 kWh 24 h"−"1 was obtained for the NERC prototype, indicating 5.45% energy consumption reduction compared with the conventional domestic refrigerator-freezer. Furthermore, the effects of system configuration parameters including the refrigerant charge amount, the compressor displacement and the length of capillary tube were investigated. This study aims at providing deep insight into ejector-expansion technology applied in domestic refrigerator-freezers. - Highlights: • A NERC (novel ejector enhanced refrigeration cycle) was experimentally studied. • 73 experimental data points with different system configuration were acquired. • Energy consumption could be reduced with optimum system configuration. • 5.45% energy consumption reduction is obtained compared with the conventional system.

Life-Cycle Evaluation of Domestic Energy Systems

Science.gov (United States)

Bando, Shigeru; Hihara, Eiji

Among the growing number of environmental issues, the global warming due to the increasing emission of greenhouse gases, such as carbon dioxide CO2, is the most serious one. In order to reduce CO2 emissions in energy use, it is necessary to reduce primary energy consumption, and to replace energy sources with alternatives that emit less CO2.One option of such ideas is to replace fossil gas for water heating with electricity generated by nuclear power, hydraulic power, and other methods with low CO2 emission. It is also important to use energy efficiently and to reduce waste heat. Co-generation system is one of the applications to be able to use waste heat from a generator as much as possible. The CO2 heat pump water heaters, the polymer electrolyte fuel cells, and the micro gas turbines have high potential for domestic energy systems. In the present study, the life-cycle cost, the life-cycle consumption of primary energy and the life-cycle emission of CO2 of these domestic energy systems are compare. The result shows that the CO2 heat pump water heaters have an ability to reduce CO2 emission by 10%, and the co-generation systems also have another ability to reduce primary energy consumption by 20%.

Energy consumption and economic growth: The case of oil exporting countries

International Nuclear Information System (INIS)

Mehrara, Mohsen

2007-01-01

This paper examines the causal relationship between the per capita energy consumption and the per capita GDP in a panel of 11 selected oil exporting countries by using panel unit-root tests and panel cointegration analysis. The results show a unidirectional strong causality from economic growth to energy consumption for the oil exporting countries. The findings have practical policy implications for decision makers in the area of macroeconomic planning. In most major oil exporting countries, government policies keep domestic prices bellow free market level, resulting in high levels of domestic energy consumption. The results imply that the energy conservation through reforming energy price policies has no damaging repercussions on economic growth for this group of countries. (author)

Four major components influence the growth of the gross domestic product in Chinese provinces: consumption, investment, transnational exports, and inter-provincial exports. By splitting a competitive input-output table into a non-competitive input-output table, this study used an input-output model to measure the contributions of the four components of gross domestic product in various regions in China. We found that international exports drove the growth of the gross domestic product more strongly in the eastern region than in other regions. Investment and inter-provincial exports were the major impetus for gross domestic product growth in the central and western regions. We also found that consumption played a minimal role in driving the growth of the gross domestic product in all regions in China. According to these findings, although various regions can share much in terms of policies to transform the impetus for economic growth, there should be different foci for different regions. Their shared policy is to increase the role of final consumption in stimulating economic growth. Region-specific policies mandate that the eastern region should strengthen the driving force provided by international exports and that the central and western regions should strengthen indigenous growth capabilities by improving scientific innovation, industrial support, and institutional innovation.

In this paper we investigate what determines observed differences in economy-wide material use among the EU-15 member states. The empirical basis for our analysis is an extended and revised material flow data set for each of the EU-15 countries in time series from 1970 to 2001. This data set comprises consistent data for domestic extraction, imports and exports as well as for derived material flow indicators, broken down by 12 types of materials. We compare the level and composition of domestic material consumption (DMC) in the EU-15 member states and identify determinants of the observed differences. Across the European Union member states overall DMC per capita varies by a factor of three ranging between 12 tonnes per capita in Italy and the United Kingdom and 37 tonnes per capita in Finland. This variability of DMC in the EU-15 is in a similar order of magnitude as the variability of GDP per capita or total primary energy supply per capita. Linear correlation analysis reveals that national income and final energy consumption relate to material use but cannot fully account for the observed differences in material consumption. By breaking down overall material flow indicators into 12 categories of materials and analysing their use patterns in detail, we identified a number of factors, socio-economic and natural, that influence the level and composition of economy-wide material use. Many of these factors are specific for certain types of materials, others are more general, and quite some driving factors counteract each other regarding the direction of their influence. Concluding we summarize the most important driving factors for domestic material consumption stressing population density as largely neglected but important explanatory variable for material use patterns, discuss issues of environmental significance, aggregation and the use of different denominators in material flow accounting and suggest a re-interpretation of DMC.

The purpose of this publication to gather together in one volume some of the more important United Kingdom data on domestic energy and the measures that have been taken to improve the efficiency with which it is used. The introductory section discusses the main underlying trends affecting domestic energy use. It is followed by six main sections: Section 1 deals with fuel prices and household expenditure on energy. Section 2 is concerned with basic statistics on population, households and the housing stock (age, tenure, dwelling type and regional distribution). Section 3 presents information on the uptake of insulation measures in the housing stock. Section 4 presents information on changes to the housing stock heat loss, heating systems, temperatures and energy use. This section looks at what would have happened to the energy use of the housing stock if energy efficiency improvements had not been introduced. Section 4 contains the main conclusions on the effectiveness of insulation, improvements in efficiency and the rising standards of service achieved within the housing stock. Section 5 draws together the topics discussed in section 4 to illustrate the individual effects of rising levels of service, external temperature variations, improved insulation and improved heating efficiency, and how these combine to determine domestic section energy consumption. Section 6 considers the fuels used to meet the energy demand of the housing stock and the carbon dioxide emissions which result from this fuel use. The primary energy consumption associated with the energy delivered to the housing stock is also addressed in this section. A final energy balance diagram draws together the various topics discussed in the report by showing the main energy flows related to the housing stock. (author)

A transversus abdominis plane block is a peripheral block method that has been used successfully for pain relief after total abdominal hysterectomy. However, the effects of the combination of the transversus abdominis plane block and general anesthesia on analgesic and anesthetic requirements remain unclear. This randomized placebo-controlled study is aimed to evaluate the effects of transversus abdominis plane block on analgesic and anesthetic consumption during total abdominal hysterectomy under general anesthesia. Sixty-six women undergoing total abdominal hysterectomy were randomized into two groups to receive general anesthesia alone (control group) or with transversus abdominis plane block using 20mL of 0.25% bupivacaine (transversus abdominis plane group). Intraoperative remifentanil and sevoflurane consumption were recorded. We also evaluated the postoperative pain, nausea, quality of recovery scores and rescue analgesic requirement during postoperative 24hours. The total remifentanil and sevoflurane consumption is significantly lower in transversus abdominis plane group; respectively mean (SD) 0.130 (0.25) vs. 0.094 (0.02) mcg.kg -1 .min -1 ; pplane group soon after surgery; median (range) 6 (2-10) vs. 3 (0-5); pplane group had significantly higher QoR-40 scores 190.5 (175-197) vs. 176.5 (141-187); pplane block with general anesthesia can provide reduced opioid and anesthetic consumption and can improve postoperative pain and quality of recovery scores in patients undergoing total abdominal hysterectomy.

Full Text Available As in other economies, consumption expenditure is the largest component of the Gross Domestic Product (GDP of Pakistan economy. The figure has been estimated around 80 percent of the GDP and demonstrates that historically, Pakistan’s economic growth is characterized as consumption-led growth. The present paper aims to explore the relationship between income and consumption using annual time series data for the period: 1975 to 2012 in Pakistan. For empirical investigation the linear regression model and the method of Least Squares is used as analytical techniques. Empirical results support the existence of a significant positive relationship between income and consumption. The finding suggests that long term committed planning is indispensable to enhance the productive capacity of the economy, employment opportunities and reduce poverty levels more effectively.

The nutrition transition model provides an integrated approach to analyse global changes in food consumption and lifestyle patterns. Whether variability in food availability for consumption, lifestyle and sociodemographic factors is associated with the worldwide prevalence distribution of overweight, obesity and hypertension is unclear. Ecological analysis. Country-specific prevalence estimates of overweight, obesity and hypertension were obtained. Prevalence estimates were then matched to year- and country-specific food and energy availability for consumption of cereals, sugar, sweeteners and honey, vegetable oils, fruits, starchy roots, pulses, total vegetables, alcoholic beverages, total meat, animal fat, eggs, milk, and fish and seafood. The per capita Gross Domestic Product (GDP), urbanization rates and prevalence of physical inactivity for each country were also obtained. The overweight, obesity and hypertension databases included information from 128, 123 and seventy-nine countries, respectively. Consumption of sugar and animal products were directly associated with GDP and urbanization rates. In a multivariate regression model, physical inactivity (B = 0·01, se = 0·005, P = 0·003), cereal consumption (B = -0·02, se = 0·006, P < 0·001) and sugar consumption (B = 0·03, se = 0·01, P = 0·03) were significant predictors of obesity prevalence. Midpoint age (B = 0·21, se = 0·10, P = 0·02), prevalence of overweight (B = 0·18, se = 0·08, P = 0·02) and consumption of cereals (B = -0·22, se = 0·10, P = 0·02) were significant predictors of hypertension. Women appeared to have a significant obesity excess compared with men. High sugar consumption and sedentary lifestyle are associated with increased obesity prevalence. The non-linear association of sugar consumption with prevalence of obesity suggests that effective strategies to reduce its consumption may have differential effects in countries at different stages of the nutrition transition.

China's energy consumption under the global economic crisis: Decomposition and sectoral analysis

International Nuclear Information System (INIS)

Li, Fangyi; Song, Zhouying; Liu, Weidong

2014-01-01

It is now widely recognized that there is a strong relationship between energy consumption and economic growth. Most countries′ energy demands declined during the economic depression of 2008–2009 when a worldwide economic crisis occurred. As an export-oriented economy, China suffered a serious exports decline in the course of the crisis. However, it was found that energy consumption continued to increase. Against such a background, this paper aims to assess and explain the factors causing the growth of energy consumption in China. First, we will explain the impact of domestic final use and international trade on energy consumption by using decomposition analysis. Second, embodied energy and its variation across sectors are quantified to identify the key sectors contributing to the growth. Lastly, the policy implications for long-term energy conservation are discussed. The results show that the decline in exports was one of the driving forces for energy consumption reduction in the crisis, but that the growth of domestic demand in manufacturing and construction, largely stimulated by economic stimulus plans, had the opposite effect on energy consumption. International trade contributed to decreasing energy consumption of China during and after the crisis because the structure of exports and imports changed in this period. - Highlights: • We analyze the reasons for China's energy consumption change under the global economic crisis during 2007–2010. • Domestic final use growth, especially in construction and manufacturing of machinery and equipment, resulted in energy consumption increase. • International trade is identified as a driver of energy consumption reduction during and after the crisis. • Increasing China's share of consumption or reducing its share of investment in the GDP can reduce national energy intensity

Known for its scale, China is the most populous country with the world’s third largest economy. In the context of rising living standards, a relatively lower share of household consumption in its GDP, a strong domestic market and globalization, China is witnessing an unavoidable increase in household consumption, related energy consumption and carbon emissions. Chinese policy decision makers and researchers are well aware of these challenges and keen to promote green lifestyles. China has developed a series of energy policies and programs, and launched a wide-range social marketing activities to promote energy conservation.

Energy sustainability: consumption, efficiency, and ...

Science.gov (United States)

One of the critical challenges in achieving sustainability is finding a way to meet the energy consumption needs of a growing population in the face of increasing economic prosperity and finite resources. According to ecological footprint computations, the global resource consumption began exceeding planetary supply in 1977 and by 2030, global energy demand, population, and gross domestic product are projected to greatly increase over 1977 levels. With the aim of finding sustainable energy solutions, we present a simple yet rigorous procedure for assessing and counterbalancing the relationship between energy demand, environmental impact, population, GDP, and energy efficiency. Our analyses indicated that infeasible increases in energy efficiency (over 100 %) would be required by 2030 to return to 1977 environmental impact levels and annual reductions (2 and 3 %) in energy demand resulted in physical, yet impractical requirements; hence, a combination of policy and technology approaches is needed to tackle this critical challenge. This work emphasizes the difficulty in moving toward energy sustainability and helps to frame possible solutions useful for policy and management. Based on projected energy consumption, environmental impact, human population, gross domestic product (GDP), and energy efficiency, for this study, we explore the increase in energy-use efficiency and the decrease in energy use intensity required to achieve sustainable environmental impact le

Econometric modeling of electricity consumption in post-war Lebanon

International Nuclear Information System (INIS)

Nasr, G.E.; Badr, E.A.; Dibeh, G.

2000-01-01

This paper applies econometric models to investigate determinants of electrical energy consumption in post-war Lebanon. The impact of the Gross Domestic Product (GDP), proxied by total imports (TI), and degree days (DD) on electricity consumption is investigated over different time spans covering the period from 1993 to 1997. The time spans are chosen according to the rationing level of electricity supply. For the 1993-1994 time span, TI is found to be a significant determinant of energy consumption, whereas, DD has a negative correlation. This inconsistency might be attributed to an extensive rationing policy followed during this period. For the 1995-1997 time span which includes reduced rationing period (1995), all electrical energy consumption determinants are found to be significant at the 5% significance level. Analysis results for the rationing free 1996-1997 time span also show the significance of TI and DD at the 5% level. Furthermore, cointegration analysis for the 1995-1997 and 1996-1997 subsets reveals the existence of a long-run relationship between all variables. In addition, error correction models for both subsets are developed to predict short-run dynamics. Finally, statistical performance measures such as mean square error, mean average deviation and mean average percentage error are presented for all models

Ekmeiro Salvador, Jesús; Moreno Rojas, Rafael; García Lorenzo, María; Cámara Martos, Fernando

2015-10-01

In order to assess the qualitative pattern of food consumption in urban families of Anzoátegui, Venezuela, 300 domestic groups that combined a total of 1 163 people were studied. The domestic dietary pattern was addressed by the method of qualitative frequency of food consumption, which applied a structured survey that yielded the usual frequency of intake of a food or food group over a given period. The information was obtained through an interview with the person responsible for the procurement of food in every home, and included basic data for the socioeconomic and nutritional profile of the families studied. The qualitative analysis of the diet was obtained by comparing the different food groups that constitute the actual consumption pattern of the population studied, with official feeding guidelines suggested for the Venezuelan population. The present study showed that the qualitative pattern of food consumption in the urban population evaluated is characterized by slightly adjusted to the promotion of health and control of diet-related diseases. The family food proved to be far from the guidelines established by the dietary guidelines for Venezuela and consumption patterns are fairly homogeneous in the different socioeconomic strata. The foods most consumed daily were salt, coffee, dressing and precooked corn flour as well as beef, chicken and the higher weekly food consumption pastas. 90% of the food consumed daily is technologically processed. The results contribute to increase knowledge about the food situation of the Venezuelan population, and technically could direct the efforts of the authorities to reconcile the development of the productive sector and food supply, whereas a pattern qualitatively inadequate intake directly affects the individual biological functioning, and results in the collective conditioning of unfavorable health states.

Studies that investigated the association between tea consumption and the risk of major cardiovascular events have reported inconsistent results. We conducted a meta-analysis of prospective observational studies in order to summarize the evidence regarding the association between tea consumption and major cardiovascular outcomes or total mortality. In July 2014, we performed electronic searches in PubMed, EmBase, and the Cochrane Library, followed by manual searches of reference lists from the resulting articles to identify other relevant studies. Prospective observational studies that reported effect estimates, with 95 % confidence intervals (CIs), for coronary heart disease (CHD), stroke, cardiac death, stroke death, or total mortality for more than two dosages of tea consumption were included. A random-effects meta-analysis was performed to determine the risk of major cardiovascular outcomes associated with an increase in tea consumption by 3 cups per day. Of the 736 citations identified from database searches, we included 22 prospective studies from 24 articles reporting data on 856,206 individuals, and including 8,459 cases of CHD, 10,572 of stroke, 5,798 cardiac deaths, 2,350 stroke deaths, and 13,722 total deaths. Overall, an increase in tea consumption by 3 cups per day was associated with a reduced risk of CHD (relative risk [RR], 0.73; 95 % CI: 0.53–0.99; P = 0.045), cardiac death (RR, 0.74; 95 % CI: 0.63–0.86; P < 0.001), stroke (RR, 0.82; 95 % CI: 0.73–0.92; P = 0.001), total mortality (RR, 0.76; 95 % CI: 0.63–0.91; P = 0.003), cerebral infarction (RR, 0.84; 95 % CI: 0.72–0.98; P = 0.023), and intracerebral hemorrhage (RR, 0.79; 95 % CI: 0.72–0.87; P < 0.001), but had little or no effect on stroke mortality (RR, 0.93; 95 % CI: 0.83–1.05; P = 0.260). The findings from this meta-analysis indicate that increased tea consumption is associated with a reduced risk of CHD, cardiac death, stroke, cerebral infarction, and

Highlights: • An alternative power management control for home appliances that require thermal regulation is presented. • A Model Predictive Control scheme is assessed and its performance studied and compared to the thermostat. • Problem formulation is explored through tuning weights with the aim of reducing energetic consumption and cost. • A modulation scheme of a two-level Model Predictive Control signal as an interface block is presented. • The implementation costs in home appliances with thermal regulation requirements are reduced. - Abstract: A vital element in making a sustainable world is correctly managing the energy in the domestic sector. Thus, this sector evidently stands as a key one for to be addressed in terms of climate change goals. Increasingly, people are aware of electricity savings by turning off the equipment that is not been used, or connect electrical loads just outside the on-peak hours. However, these few efforts are not enough to reduce the global energy consumption, which is increasing. Much of the reduction was due to technological improvements, however with the advancing of the years new types of control arise. Domestic appliances with the purpose of heating and cooling rely on thermostatic regulation technique. The study in this paper is focused on the subject of an alternative power management control for home appliances that require thermal regulation. In this paper a Model Predictive Control scheme is assessed and its performance studied and compared to the thermostat with the aim of minimizing the cooling energy consumption through the minimization of the energy cost while satisfying the adequate temperature range for the human comfort. In addition, the Model Predictive Control problem formulation is explored through tuning weights with the aim of reducing energetic consumption and cost. For this purpose, the typical consumption of a 24 h period of a summer day was simulated a three-level tariff scheme was used. The new

Renata Mourão Macedo

2015-12-01

Full Text Available The paper reflects on the articulation of social categories of difference and intersectionalities from the analysis of a domestic worker trajectory, who is in transition to the profession of nursing assistant. I argue that, in the analyzed trajectory, the professional qualification and the possibility to consume some goods, before accessible only to middle and upper classes, were prominent in the search for agency, achievements facilitated by a favorable socio-economic context. Through an anthropological perspective, the purpose of the paper is to contribute to the debate on the articulation of categories such as gender, class and race, focusing on the agency possibilities in contexts marked by inequalities.

According to the data of the Estonian Statistics Department the consumption of fuels in Estonia over the period of January-June 1993 was a follows: coal 77,053 t, oil shale 7,981,840 t, fuel peat 127,376 t, peat briquette 42,041 t, firewood 154,511 solid metres, wood chip 55,648 solid metres. The consumption of fuel peat (chiefly for producing briquette) was more considerable in the town of Kohtla-Jaerve and in the districts of Paernu and Tartu where Estonia's major peat-briquette plants are located. The share of peat in the other industries has been less significant. (author)

This paper investigated the empirical relationship between economy development and energy consumption by material production, nonmaterial production and household. Empirical models accounting for the key influential factors were constructed. Ordinary Least Square Regression (OLS) analysis of the official data of China for the year 1985-2007 permitted the relationship between individual energy consumption components and the corresponding coefficients to be investigated. The results showed that (1) the Unit Energy Consumption by Primary Industry (UECPI), Secondary Industry (UECSI), and Tertiary Industry (UECTI) demonstrated an inverse relationship with Gross Domestic Product (GDP); (2) a linear relationship exists between the Energy Consumption by Nonmaterial Production (ECNP) and GDP; (3) the hypotheses that there is an inverse S-shaped relationship between Unit Energy Consumption by Household (UECH) and Personal Income (PI) is valid. Based on the above findings and an analysis of China's energy policies, suggestions on China's energy policy were given in the end. -- Highlights: → Decomposed total energy consumption in three parts, branch of material produces, branch of the immaterial production, and households. → Energy consumed by branch of material produces considered the economic scale and construction. → Energy consumed by immaterial production was first referred in this article. → The relationship between energy consumed by household and GDP fits the invert-S curve, which is first referred too.

Significant effort has been exerted on the study of economic variables such as absolute energy prices to understand energy consumption and economic growth. However, this approach ignores general inflation effects, whereby the prices of baskets of goods may rise or fall at different rates from those of energy prices. Thus, it may be the relative energy price, not the absolute energy price, that has most important effects on energy consumption. To test this hypothesis, we introduce a new explanatory variable, the domestic relative energy price, which we define as "the ratio of domestic energy prices to the general price level of an economy," and we test the explanatory power of this new variable. Thus, this paper explores the relationship between relative energy prices and energy consumption in China from the perspective of inflation costs over the period from 1988 to 2012. The direct, regulatory and time-varying effects are captured using methods such as ridge regression and the state-space model. The direct impacts of relative energy prices on total energy consumption and intensity are -0.337 and -0.250, respectively; the effects of comprehensive regulation on energy consumption through the economic structure and the energy structure are -0.144 and -0.148, respectively; and the depressing and upward effects of rising and falling energy prices on energy consumption are 0.3520 and 0.3564, respectively. When economic growth and the energy price level were stable, inflation persisted; thus, rising energy prices benefitted both the economy and the environment. Our analysis is important for policy makers to establish effective energy-pricing policies that ensure both energy conservation and the stability of the pricing system.

Reliable energy consumption forecasting can provide effective decision-making support for planning development strategies to energy enterprises and for establishing national energy policies. Accordingly, the present study aims to apply a hybrid intelligent approach named ADE–BPNN, the back-propagation neural network (BPNN) model supported by an adaptive differential evolution algorithm, to estimate energy consumption. Most often, energy consumption is influenced by socioeconomic factors. The proposed hybrid model incorporates gross domestic product, population, import, and export data as inputs. An improved differential evolution with adaptive mutation and crossover is utilized to find appropriate global initial connection weights and thresholds to enhance the forecasting performance of the BPNN. A comparative example and two extended examples are utilized to validate the applicability and accuracy of the proposed ADE–BPNN model. Errors of the test data sets indicate that the ADE–BPNN model can effectively predict energy consumption compared with the traditional back-propagation neural network model and other popular existing models. Moreover, mean impact value based analysis is conducted for electrical energy consumption in U.S. and total energy consumption forecasting in China to quantitatively explore the relative importance of each input variable for the improvement of effective energy consumption prediction. - Highlights: • Enhanced back-propagation neural network (ADE-BPNN) for energy consumption forecasting. • ADE-BPNN outperforms the current best models for two comparative cases. • Mean impact value approach explores socio-economic factors' relative importance. • ADE-BPNN's adjusted goodness-of-fit is 99.2% for China's energy consumption forecasting.

A missing link? The case of Norway and Sweden: Does increased renewable energy production impact domestic greenhouse gas emissions?

International Nuclear Information System (INIS)

Blindheim, Bernt

2015-01-01

This article examines how the EU's RES directive will impact domestic greenhouse gas emissions in Norway and Sweden by 2020. The directive aims for a higher RES share in the energy consumption mix, and Norway and Sweden have established a common electricity certificate scheme to help achieve these RES goals. In terms of how these two national RES plans will impact domestic emissions by 2020, factors such as nuclear power, consumption changes and the energy balance must be considered. The most practical approach to evaluate the plans’ impact on emissions is to focus on changes in carbon-based consumption within the three directive sectors. The Norwegian RES action plan will not affect domestic emissions unless the electricity surplus generated by the certificate market is used to phase out fossil fuels in domestic sectors beyond the scope of the RES directive. The use of electricity to phase out fossil fuel consumption in the offshore sector would substantially reduce Norwegian emissions figures. The Swedish plan would positively impact Swedish greenhouse gas emissions; however, this impact is limited, primarily because a substantial increase in energy consumption is expected. - Highlights: • Implementation of the EU directive on use of energy from renewable sources (RES). • A comparison between Norway and Sweden. • The common green certificate market. • Does increased share of renewable energy impact on greenhouse gas emissions. • Calculations indicate that increased RES share has limited impact on emissions

Domestic violence is an important health concern that has been shown to have adverse effects on maternal and neonatal outcomes. The objectives of this study were to compare the prevalence of prenatal screening for domestic violence in a hospital-based resident clinic setting with screening practices in private obstetric offices in Honolulu, Hawai'i and to explore physician attitudes towards domestic violence screening during pregnancy. A retrospective chart review was conducted at Queen's Medical Center in Honolulu, Hawai'i in women who delivered between 2003 and 2004. A 6 item written survey was also given to all attending and resident physicians with obstetric privileges. Descriptive statistics including frequency measures were generated and chi square tests were used to compare categorical variables. A total of 270 charts were reviewed. There was a statistically significant difference (p obstetric practices (39.3 percent) that were screened for domestic violence. While the majority of respondents (77.6%) to the domestic violence survey were aware that the American College of Obstetricians and Gynecologists recommends domestic violence screening in pregnancy most respondents (69.0 percent) indicated that they "never or rarely" screened their patients for domestic violence. Despite professional recommendations and an awareness of these recommendations, between 2003 and 2004, routine prenatal screening for domestic violence was markedly lacking for patients in this study population.

The domestic natural gas industry in developing countries

The domestic natural gas industry has generally exhibited slow growth in most developing countries that are fortunate enough to have sufficient proved gas reserves to meet energy needs. But supportive government policies that promote the use of indigenous reserves are now beginning to have a positive impact in many parts of the world. Supply and distribution infrastructures are being built or modernized. And natural gas is now or will be available at prices that encourage the displacement of competitive fuels in the larger, energy-intensive industrial and power-generation markets of these countries. It is expected that the domestic gas industry in many developing countries will expand at higher rates than in the past. In the next few decades, the resulting benefits will include reductions in oil consumption per capita, improvements in the balance of payments for oil-importing and exporting developing countries, greater efficiency of energy usage and lower energy consumption per output unit, and improved environmental quality. The national economies and living standards will also undergo significant advancement

Approximately 8 per cent of the carbon dioxide (CO{sub 2}) emissions produced in the United Kingdom are produced in London, one of the fastest growing cities worldwide. Based on the projected rates of population and economic growth, a 15 per cent increase of emissions is predicted. In addition to the national target to cut emissions by 80 per cent by 2050, the Mayor of London Climate Change Action Plan set a target to reduce London's CO{sub 2} emissions by 60 per cent by 2025. Significant carbon savings can be achieved in the building sector, particularly since 38 per cent of the total delivered energy in London is associated with domestic energy use. This paper demonstrated a systematic approach towards exploring the impact of urban built form and the combined effect of climate change and the urban heat island (UHI) phenomenon on the levels of domestic energy consumption and heat-related health risk in London. It presented work in progress on the development of a GIS-based energy consumption model and heat vulnerability index of the Greater London Area domestic stock. Comparison of the model output for 10 case study areas with topdown energy statistics revealed that the model successfully ranks areas based on their domestic space heating demand. The health module can be used to determine environments prone to higher risk of heat stress by investigating urban texture factors. A newly developed epidemiological model will be feed into the health module to examine the influence on risk of heat-related mortality of local urban built form characteristics. The epidemiological model is based on multi-variable analysis of deaths during heat wave and non-heat wave days. 29 refs., 1 tab., 7 figs.

Excessive use of firewood, as a primary source of energy for domestic purposes, is leading to severe deforestation in the northeastern Himalayan region. Firewood consumption pattern of three tribal communities of Meghalaya, India- Garo, Khasi and Jaintia was studied under varying ecological, socio-economic and socio-cultural conditions. Fuelwood consumption was highest to Khasi community (5.81 kg/capita/day), followed by the Garo (5.32 kg/capita/day) and Jaintia (3.90 kg/capita/day), respectively, irrespective of their socio-economic status. The labour energy expenditure for fuelwood collection was highest for the Jaintia (88.56 MJ/capita/yr) and minimum to Garo (70.64 MJ/capita/yr). The fuelwood is burnt for various activities such as cooking, water heating, space heating, lighting and livestock rearing, etc. Among various activities, cooking required maximum energy. Commercial fuel is beyond the reach of the tribal communities due to their poor socio-economic conditions. The estimated growing stock is unable to sustain the rate of fuel consumption. This information could be utilized for developing appropriate technology for afforestation programmes in this region since 90% of the total population use biomass as an important source of energy

Description of 2005-10 domestic water use for selected U.S. cities and guidance for estimating domestic water use

Domestic water-use and related socioeconomic and climatic data for 2005-10 were used in an analysis of 21 selected U.S. cities to describe recent domestic per capita water use, investigate variables that potentially affect domestic water use, and provide guidance for estimating domestic water use. Domestic water use may be affected by a combination of several factors. Domestic per capita water use for the selected cities ranged from a median annual average of 43 to 177 gallons per capita per day (gpcd). In terms of year-to-year variability in domestic per capita water use for the selected cities, the difference from the median ranged from ± 7 to ± 26 percent with an overall median variability of ± 14 percent. As a percentage of total annual water use, median annual domestic water use for the selected cities ranged from 33 to 71 percent with an overall median of 57 percent. Monthly production and water sales data were used to calculate daily per capita water use rates for the lowest 3 consecutive months (low-3) and the highest 3 consecutive months (high-3) of usage. Median low-3 domestic per capita water use for 16 selected cities ranged from 40 to 100 gpcd. Median high-3 domestic per capita water use for 16 selected cities ranged from 53 to 316 gpcd. In general, the median domestic water use as a percentage of the median total water use for 16 selected cities was similar for the low-3 and high-3 periods. Statistical analyses of combined data for the selected cities indicated that none of the socioeconomic variables, including cost of water, were potentially useful as determinants of domestic water use at the national level. However, specific socioeconomic variables may be useful for the estimation of domestic water use at the State or local level. Different socioeconomic variables may be useful in different States. Statistical analyses indicated that specific climatic variables may be useful for the estimation of domestic water use for some, but not all, of the

Tracking antibiotic consumption patterns over time and across countries could inform policies to optimize antibiotic prescribing and minimize antibiotic resistance, such as setting and enforcing per capita consumption targets or aiding investments in alternatives to antibiotics. In this study, we analyzed the trends and drivers of antibiotic consumption from 2000 to 2015 in 76 countries and projected total global antibiotic consumption through 2030. Between 2000 and 2015, antibiotic consumption, expressed in defined daily doses (DDD), increased 65% (21.1–34.8 billion DDDs), and the antibiotic consumption rate increased 39% (11.3–15.7 DDDs per 1,000 inhabitants per day). The increase was driven by low- and middle-income countries (LMICs), where rising consumption was correlated with gross domestic product per capita (GDPPC) growth (P = 0.004). In high-income countries (HICs), although overall consumption increased modestly, DDDs per 1,000 inhabitants per day fell 4%, and there was no correlation with GDPPC. Of particular concern was the rapid increase in the use of last-resort compounds, both in HICs and LMICs, such as glycylcyclines, oxazolidinones, carbapenems, and polymyxins. Projections of global antibiotic consumption in 2030, assuming no policy changes, were up to 200% higher than the 42 billion DDDs estimated in 2015. Although antibiotic consumption rates in most LMICs remain lower than in HICs despite higher bacterial disease burden, consumption in LMICs is rapidly converging to rates similar to HICs. Reducing global consumption is critical for reducing the threat of antibiotic resistance, but reduction efforts must balance access limitations in LMICs and take account of local and global resistance patterns.

In this work the experimental methodology developed to carry out tests of the electrical energy of refrigerators consumption as norm NOM-015-ENER-2002 is described. The tests were made in the Laboratory of Controlled Environment of the Iztapalapa Unit of the Universidad Autonoma Metropolitana to a sample of old domestic refrigerators in operation. The results found show that the consumption of electrical energy of refrigerators of more than 10 years of age can be higher than 60% of what a modern refrigerator of high efficiency would consume, or 30% higher if the refrigerator was made between 1997 and 2002. With these results it is sustained, in a more complete way, the evaluation of the saving potential of the national electrical energy by the substitution of old domestic refrigerators by modern, as reported in a previous work. [Spanish] En este trabajo se describe la metodologia experimental desarrollada para efectuar pruebas del consumo de energia electrica a refrigeradores conforme la norma NOM-015-ENER-2002. Las pruebas se realizaron en el Laboratorio de Ambiente Controlado de la Unidad Iztapalapa de la Universidad Autonoma Metropolitana a una muestra de refrigeradores domesticos antiguos en operacion. Los resultados encontrados muestran que el consumo de energia electrica de refrigeradores de mas de 10 anos de antig�edad puede superior al 60% de lo que consumiria un refrigerador moderno de alta eficiencia, o superior en un 30% si el refrigerador fue fabricado entre 1997 y 2002. Con estos resultados se sustenta de manera mas completa la evaluacion del potencial de ahorro de energia electrica nacional por substitucion de refrigeradores domesticos antiguos por modernos reportado en un trabajo anterior.

Full Text Available The oxalate content of beetroot, carrot, celeriac and parsnip after freezing by traditional and modified methods (the latter resulting in a convenience food product, and after the preparation of frozen products for consumption was evaluated. The highest content of total and soluble oxalates (105 and 82 mg 100 g-1 fresh matter was found in beetroot. The lowest proportion (55% of soluble oxalates was noted in celeriac; this proportion was higher in the remaining vegetables, being broadly similar for each of them. Blanching brought about a significant decrease in total and soluble oxalates in fresh vegetables. Cooking resulted in a higher loss of oxalates. The level of oxalates in products prepared for consumption directly after freezing approximated that before freezing. Compared with the content before freezing, vegetables prepared for consumption by cooking after frozen storage contained less oxalates, except for total oxalates in parsnip and soluble oxalates in beetroot and celeriac. The highest ratio of oxalates to calcium was found in raw beetroot; it was two times lower in raw carrot; five times lower in raw celeriac; and eight times lower in raw parsnip. These ratios were lower after technological and culinary processing. The percentage of oxalate bound calcium depended on the species; this parameter was not significantly affected by the procedures applied. The true retention of oxalates according to Judprasong et al. (2006 was lower than retention calculated taking its content in 100 g fresh matter into account.;

Raw material consumption of the European Union--concept, calculation method, and results.

This article presents the concept, calculation method, and first results of the "Raw Material Consumption" (RMC) economy-wide material flow indicator for the European Union (EU). The RMC measures the final domestic consumption of products in terms of raw material equivalents (RME), i.e. raw materials used in the complete production chain of consumed products. We employed the hybrid input-output life cycle assessment method to calculate RMC. We first developed a highly disaggregated environmentally extended mixed unit input output table and then applied life cycle inventory data for imported products without appropriate representation of production within the domestic economy. Lastly, we treated capital formation as intermediate consumption. Our results show that services, often considered as a solution for dematerialization, account for a significant part of EU raw material consumption, which emphasizes the need to focus on the full production chains and dematerialization of services. Comparison of the EU's RMC with its domestic extraction shows that the EU is nearly self-sufficient in biomass and nonmetallic minerals but extremely dependent on direct and indirect imports of fossil energy carriers and metal ores. This implies an export of environmental burden related to extraction and primary processing of these materials to the rest of the world. Our results demonstrate that internalizing capital formation has significant influence on the calculated RMC.

Domestic cats are one of the most popular pets globally, but the process of their domestication is not well understood. Near Eastern wildcats are thought to have been attracted to food sources in early agricultural settlements, following a commensal pathway to domestication. Early evidence for close human-cat relationships comes from a wildcat interred near a human on Cyprus ca. 9,500 y ago, but the earliest domestic cats are known only from Egyptian art dating to 4,000 y ago. Evidence is lacking from the key period of cat domestication 9,500-4,000 y ago. We report on the presence of cats directly dated between 5560-5280 cal B.P. in the early agricultural village of Quanhucun in Shaanxi, China. These cats were outside the wild range of Near Eastern wildcats and biometrically smaller, but within the size-range of domestic cats. The δ(13)C and δ(15)N values of human and animal bone collagen revealed substantial consumption of millet-based foods by humans, rodents, and cats. Ceramic storage containers designed to exclude rodents indicated a threat to stored grain in Yangshao villages. Taken together, isotopic and archaeological data demonstrate that cats were advantageous for ancient farmers. Isotopic data also show that one cat ate less meat and consumed more millet-based foods than expected, indicating that it scavenged among or was fed by people. This study offers fresh perspectives on cat domestication, providing the earliest known evidence for commensal relationships between people and cats.

Consumer's preference and consumption pattern of biomass fuel, fuel types and energy use category has been studied in the disregarded villages of Bangladesh. The study was conducted both in the inland and island areas. Biomass energy in the study area was used in domestic cooking, tea stalls, brickfields, bakeries, paddy parboiling and pottery. Assessment of consumption in domestic cooking was done by means of multistage random sampling and that in the tea stalls, brickfields, bakeries, paddy parboiling and pottery by means of complete enumeration of the sampling unit. Based on the homestead size respondents were categorized into small, medium and large and a total of 60 homesteads (30 from inland and another 30 from island areas), 20 from each category were selected randomly for the study. The study revealed that natural gas was quite absent and stems, branches and twigs, leaves of trees, agricultural residues, shell and coir of coconut, saw dust, brush wood, rhizomes of bamboo, and cowdung were the biomass fuel used by the respondent. Nine fuelwood species were identified as the most preferred in the study area. Consumption pattern was mostly traditional. Each year preceding the rainy season cyclonic action damages a large quantity of biomass energy sources. Though at the initial stage of rainy season (April-May) there remain a more or less good collection of fuelwood to the user as the byproduct of cyclones and storms, the last part of the rainy season (July-August) was identified as the fuel shortage period.

IntroductionThe U.S. Geological Survey (USGS) National Water Use Science Project (NWUSP), part of the USGS Water Availability and Use Science Program (WAUSP), has estimated water use in the United States every 5 years since 1950. This report provides an overview of total population, public-supply use, including the population that is served by public-supply systems and the domestic deliveries to those users, and self-supplied domestic water use in the United States for 2015, continuing the task of estimating water use in the United States every 5 years. In this report, estimates for the United States include the 50 States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands (hereafter referred to as “states” for brevity).County-level data for total population, public-supply withdrawals and the population served by public-supply systems, and domestic withdrawals for 2015 were published in a data release in an effort to provide data to the public in a timely manner. Data in the current version (1.0) of Dieter and others (2017) contains county-level total withdrawals from groundwater and surface-water sources (both fresh and saline) for public-water supply, the deliveries from those suppliers to domestic users, and the quantities of water from groundwater and surface-water sources for self-supplied domestic users, and total population. Methods used to estimate the various data elements for the public-supply and domestic use categories at the county level are described by Bradley (2017).This Open-File Report is an interim report summarizing the data published in Dieter and others (2017) at the state and national level. This report includes discussions on the total population, totals for public-supply withdrawals and population served, total domestic withdrawals, and provides comparisons of the 2015 estimates to 2010 estimates (Maupin and others, 2014). Total domestic water use, as described in this report, represents the summation of deliveries from

The effects of transversus abdominis plane block on analgesic and anesthetic consumption during total abdominal hysterectomy: a randomized controlled study

Full Text Available Abstract Background and objectives: A transversus abdominis plane block is a peripheral block method that has been used successfully for pain relief after total abdominal hysterectomy. However, the effects of the combination of the transversus abdominis plane block and general anesthesia on analgesic and anesthetic requirements remain unclear. This randomized placebo-controlled study is aimed to evaluate the effects of transversus abdominis plane block on analgesic and anesthetic consumption during total abdominal hysterectomy under general anesthesia. Methods: Sixty-six women undergoing total abdominal hysterectomy were randomized into two groups to receive general anesthesia alone (control group or with transversus abdominis plane block using 20 mL of 0.25% bupivacaine (transversus abdominis plane group. Intraoperative remifentanil and sevoflurane consumption were recorded. We also evaluated the postoperative pain, nausea, quality of recovery scores and rescue analgesic requirement during postoperative 24 hours. Results: The total remifentanil and sevoflurane consumption is significantly lower in transversus abdominis plane group; respectively mean (SD 0.130 (0.25 vs. 0.094 (0.02 mcg.kg-1.min-1; p < 0.01 and 0.295 (0.05 vs. 0.243 (0.06 mL.min-1; p < 0.01. In the postoperative period, pain scores were significantly reduced in transversus abdominis plane group soon after surgery; median (range 6 (2-10 vs. 3 (0-5; p < 0.001, at 2 h (5 [3-9] vs. 2.5 [0-6]; p < 0.001, at 6 h (4 [2-7] vs. 3[0-6], p < 0.001, at 12 h (3.5 [1-6] vs. 2 [1-5]; p = 0.003. The patients in the transversus abdominis plane group had significantly higher QoR-40 scores 190.5 (175-197 vs. 176.5 (141-187; p < 0.001. Conclusion: Combining transversus abdominis plane block with general anesthesia can provide reduced opioid and anesthetic consumption and can improve postoperative pain and quality of recovery scores in patients undergoing total abdominal hysterectomy.

They´re assigned to four diets: elephant grass (Pennisetum purpureum Schum. silage; elephant grass silage and commercial concentrate; chopped sugar cane and urea; chopped sugar cane, urea and commercial concentrate. The chromic oxide underestimated the heifers consumption of all diets and its estimates differed from either hod consumption or those obtained with markers. LIPE® may replace chromic oxide because its consumption estimates did not differ from hod consumption of all diets. The lignin Klason showed to be more appropriate to estimate the heifers consumption that were fed with diets based on grass silage than those heifers fed with sugarcane. This marker underestimated the consumption of heifers that received sugarcane and urea (3,57kg/day of MS when it was compared to the consumption registered in hod (4,05kg/day of MS, however, for those heifers that received sugarcane, urea and supply, lignin Klason underestimated the consumption (3,90kg/day of MS, so that, it differed form consumption in hod (4,90kg/day of MS. The indigestible fibers (FDAi and FDNi were suitable to estimate the heifers consumption in all diets.

The power crisis problem is getting worse in the developing countries. Measures are being taken to overcome the power shortage problem by efficiently utilizing the available power. Replacement of high-power consumption lamps with energy efficient lamps is also among these steps. This paper presents a detailed comparative analysis between domestic lighting lamps (DLLs) use for producing artificial light. DLLs include incandescent lamp (IL), fluorescent lamp (FL) and compact fluorescent lamp (CFL). Light emitting diodes (LED) based lamp technology is relatively new in comparison with conventional incandescent and discharge lamps. However, the present study will also cover the LED lamps. Power quality based experiments have been conducted on DLLs in Power System Laboratory and power consumption based calculations are carried out using the lighting design software DIALux. The result shows that with the current technology, the use of FL and LED lamp is beneficial for utility as well as for consumer. However, with the current pace in the development of LED technology, it is possible LED lamps will lead the lighting market in the near future. The paper has also presented the uncertainties that exist in lighting market and proposed the guidelines that will help in making future energy policy. - Highlights: ► Performances of domestic lighting lamps are compared. ► Power quality and power consumption based case study results are presented. ► For future energy policies, recommendations are also given.

It is likely that the production and distribution of domestic hot water (DHW) in buildings will constitute a dominant share of both the present and in particular future energy design requirements. The goal of this project has been to propose more energy efficient and environmentally friendly solutions for DHW systems based on analyses of existing conditions. The possibilities include new types of circulation pipes, which have the potential of a 40 per cent reduction of heat losses. In addition to the reduction of heat losses inside the building, a low return temperature from the hot water system will have a large impact on the heat losses from the district heating network when the building is being heated by district heating. The results of this project could influence not only future buildings but also existing buildings in case of renovation of the installations. In this project measurements of water and energy consumptions have been carried out in a number of buildings, and heat losses from the production of domestic hot water and the distribution lines have been measured. In addition to the measurements, analyses and simulations have been carried out. Two models have been developed: One of an apartment room with vertical pipes passing through the room, and one of a room above a basement with horizontal heating pipes. The models make it possible to assess how much of the heat loss from the heating pipes is utilised for space heating. The following recommendations are pointed out: 1) In large buildings e.g. apartment buildings and office buildings the technical installations should be provided with meters so that it is possible to separate the energy consumption for DHW, space heating and ventilation, respectively. 2) In new buildings and in case of retrofitting existing buildings, careful planning of the placement and disposition of hot water taps compared with the location of the hot water tank or heat exchanger is recommended. Also, the necessity of a

Background: Cashews are the third most-consumed tree nut in the United States and are abundant with monounsaturated fatty acids and polyunsaturated fatty acids, which are associated with reduced cardiovascular disease risk. Although a qualified Food and Drug Administration health claim exists for nuts and heart health, cashews have been exempt from its use because cashews exceed the disqualifying amount of saturated fatty acids. Approximately one-third of the saturated fat in cashews is stearic acid, which is relatively neutral on blood lipids, thereby suggesting that cashews could have effects that are similar to those of other nuts. However, clinical data on cashews and blood lipids have been limited. Objective: We investigated the effect of reasonable intakes of cashews on serum lipids in adults with or at risk of high LDL cholesterol. Design: In a randomized, crossover, isocaloric, controlled-feeding study, 51 men and women (aged 21-73 y) with a median LDL-cholesterol concentration of 159 mg/dL (95% CI: 146, 165 mg/dL) at screening consumed typical American diets with cashews (28-64 g/d; 50% of kilocalories from carbohydrate, 18% of kilocalories from protein, and 32% of kilocalories from total fat) or potato chips (control; 54% of kilocalories from carbohydrate, 18% of kilocalories from protein, and 29% of kilocalories from total fat) for 28 d with a ≥2-wk washout period. Results: Consumption of the cashew diet resulted in a significantly greater median change from baseline (compared with the control, all P cholesterol [-3.9% (95% CI: -9.3%, 1.7%) compared with 0.8% (95% CI: -1.5%, 4.5%), respectively], LDL cholesterol [-4.8% (95% CI: -12.6%, 3.1%) compared with 1.2% (95% CI: -2.3%, 7.8%), respectively], non-HDL cholesterol [-5.3% (95% CI: -8.6%, 2.1%) compared with 1.7% (95% CI: -0.9%, 5.6%), respectively], and the total-cholesterol:HDL-cholesterol ratio [-0.0% (95% CI: -4.3%, 4.8%) compared with 3.4% (95% CI: 0.6%, 5.2%), respectively].

Various recommendations exist for total water intake (TWI), yet it is seldom reported in dietary surveys. Few studies have examined how real-life consumption patterns, including beverage type, variety and timing relate to TWI and energy intake (EI). We analysed weighed dietary records from the National Diet and Nutrition Survey of 1724 British adults aged 19-64 years (2000/2001) to investigate beverage consumption patterns over 24 hrs and 7 days and associations with TWI and EI. TWI was calculated from the nutrient composition of each item of food and drink and compared with reference values. Mean TWI was 2.53 L (SD 0.86) for men and 2.03 L (SD 0.71) for women, close to the European Food Safety Authority "adequate Intake" (AI) of 2.5 L and 2 L, respectively. However, for 33% of men and 23% of women TWI was below AI and TWI:EI ratio was Beverages accounted for 75% of TWI. Beverage variety was correlated with TWI (r 0.34) and more weakly with EI (r 0.16). Beverage consumption peaked at 0800 hrs (mainly hot beverages/ milk) and 2100 hrs (mainly alcohol). Total beverage consumption was higher at weekends, especially among men. Overall, beverages supplied 16% of EI (men 17%, women 14%), alcoholic drinks contributed 9% (men) and 5% (women), milk 5-6%, caloric soft drinks 2%, and fruit juice 1%.In multi-variable regression (adjusted for sex, age, body weight, smoking, dieting, activity level and mis-reporting), replacing 100 g of caloric beverages (milk, fruit juice, caloric soft drinks and alcohol) with 100 g non-caloric drinks (diet soft drinks, hot beverages and water) was associated with a reduction in EI of 15 kcal, or 34 kcal if food energy were unchanged. Using within-person data (deviations from 7-day mean) each 100 g change in caloric beverages was associated with 29 kcal change in EI or 35 kcal if food energy were constant. By comparison the calculated energy content of caloric drinks consumed was 47 kcal/100 g. TWI and beverage consumption are closely related

Evaluating Domestic Hot Water Distribution System Options With Validated Analysis Models

Energy Technology Data Exchange (ETDEWEB)

Weitzel, E.; Hoeschele, M.

2014-09-01

A developing body of work is forming that collects data on domestic hot water consumption, water use behaviors, and energy efficiency of various distribution systems. A full distribution system developed in TRNSYS has been validated using field monitoring data and then exercised in a number of climates to understand climate impact on performance. This study builds upon previous analysis modelling work to evaluate differing distribution systems and the sensitivities of water heating energy and water use efficiency to variations of climate, load, distribution type, insulation and compact plumbing practices. Overall 124 different TRNSYS models were simulated. Of the configurations evaluated, distribution losses account for 13-29% of the total water heating energy use and water use efficiency ranges from 11-22%. The base case, an uninsulated trunk and branch system sees the most improvement in energy consumption by insulating and locating the water heater central to all fixtures. Demand recirculation systems are not projected to provide significant energy savings and in some cases increase energy consumption. Water use is most efficient with demand recirculation systems, followed by the insulated trunk and branch system with a central water heater. Compact plumbing practices and insulation have the most impact on energy consumption (2-6% for insulation and 3-4% per 10 gallons of enclosed volume reduced). The results of this work are useful in informing future development of water heating best practices guides as well as more accurate (and simulation time efficient) distribution models for annual whole house simulation programs.

In this paper, the authors develop and test a model to explain travel expenditures in the United States by Canadians. The model examines a consumer's choice problem where income is allocated between domestic and foreign consumption. Consumers do not know the foreign price level and base their spending in part on expected foreign price. In addition to expected foreign price, domestic price, exchange rates, income, and foreign price uncertainty influence travel spending. Empirically, each deter...

This study aimed to identify factors associated with treatment of victims of domestic and family violence in emergency rooms in Brazil. This is a case-control study based on the Surveillance System for Violence and Accidents (VIVA), 2011. Women ≥ 18 years who were victims of family and domestic violence were selected as cases and compared to accident victims (controls). Adjusted odds ratios were estimated by unconditional logistic regression. 623 cases and 10,120 controls were included. Risk factors according to the adjusted analysis were younger age (18-29 years), low schooling, lack of paid work, alcohol consumption, having sought treatment in a different health service, and violence on weekends or at night or in the early morning hours. The study concludes that domestic and family violence shows alcohol consumption as a strongly associated factor. Days and hours with the highest ocurrence reveal the need to adjust emergency services to treat victims.

ENERGY CONSUMPTION AND REAL GDP IN IRAN

2014-01-01

Full Text Available As one of the most important production factors and one of the most urgent final products, energy has a special position in the growth and development of the country. This paper examines the causal relationship between Real GDP and energy consumption in various economic sectors including (household and commercial, industry, transportation and agriculture sectors for Iran during 1967–2010 using the time series technique known as the Toda-Yamamoto method. Moreover, an error correction model is also estimated so that the results of these two methods are compared. We found a strong unidirectional causality from energy consumption in industry sector to real gross domestic product. Energy consumption in industry sector can observably promote the development of economy.

Law proposal aiming at imposing the domestic consumption tax to the natural gas used for hydrogen generation for petroleum refining purposes

International Nuclear Information System (INIS)

2009-04-01

In France, natural gas benefits from tax exemptions in several situations and in particular when used as raw material for hydrogen generation, which in turn, is used for crude oil refining and fuels generation. However, crude oil is cheaper when it is heavier but more hydrogen, and thus more natural gas, is needed to refine it and more CO 2 is released in the atmosphere. Therefore, refining cheap crude oil increases the refining margins of oil companies but their environmental impact as well. The aim of this law proposal is to impose the domestic consumption tax to natural gas when used in oil refining processes in order to finance the development of the renewable hydrogen industry through the creation of a High Council of Hydrogen Industry. This High Council would be in charge of promoting the development of renewable hydrogen production facilities and distribution circuits, of hydrogen-fueled vehicles, and of fuel cells. (J.S.)

Electricity consumption and economic growth: a time series experience for 17 African countries

2006-01-01

While the availability of electricity by itself is not a panacea for the economic and social problems facing Africa, the supply of electricity is nevertheless believed to be a necessary requirement for Africa's economic and social development. This paper tests the long-run and causal relationship between electricity consumption per capita and real gross domestic product (GDP) per capita for 17 African countries for the period 1971-2001 using a newly developed cointegration test proposed by Pesaran et al. (2001) and using a modified version of the Granger causality test due to Toda and Yamamoto (1995). The advantage of using these two approaches is that they both avoid the pre-testing bias associated with conventional unit root and cointegration tests. The empirical evidence shows that there was a long-run relationship between electricity consumption per capita and real GDP per capita for only 9 countries and Granger causality for only 12 countries. For 6 countries there was a positive uni-directional causality running from real GDP per capita to electricity consumption per capita; an opposite causality for 3 countries and bi-directional causality for the remaining 3 countries. The result should, however, be interpreted with care as electricity consumption accounts for less than 4% of total energy consumption in Africa and only grid-supplied electricity is taken into account

Water footprints of cities - indicators for sustainable consumption and production

Science.gov (United States)

Hoff, H.; Döll, P.; Fader, M.; Gerten, D.; Hauser, S.; Siebert, S.

2014-01-01

Water footprints have been proposed as sustainability indicators, relating the consumption of goods like food to the amount of water necessary for their production and the impacts of that water use in the source regions. We further developed the existing water footprint methodology, by globally resolving virtual water flows from production to consumption regions for major food crops at 5 arcmin spatial resolution. We distinguished domestic and international flows, and assessed local impacts of export production. Applying this method to three exemplary cities, Berlin, Delhi and Lagos, we find major differences in amounts, composition, and origin of green and blue virtual water imports, due to differences in diets, trade integration and crop water productivities in the source regions. While almost all of Delhi's and Lagos' virtual water imports are of domestic origin, Berlin on average imports from more than 4000 km distance, in particular soy (livestock feed), coffee and cocoa. While 42% of Delhi's virtual water imports are blue water based, the fractions for Berlin and Lagos are 2 and 0.5%, respectively, roughly equal to the water volumes abstracted in these two cities for domestic water use. Some of the external source regions of Berlin's virtual water imports appear to be critically water scarce and/or food insecure. However, for deriving recommendations on sustainable consumption and trade, further analysis of context-specific costs and benefits associated with export production will be required.

Mild weather slows increase in Finnish electricity consumption

Electricity usage in Finland increased by 1.7%, equivalent to 2.8% when adjusted for temperature and calendar factors, and totalled 79.1 billion kWh, an increase of 1.3 billion kWh on 1999. If temperatures had followed the normal pattern last year, the 80 billion kilowatt hour-barrier would have been broken. Some 60% of the increase in consumption was covered by imports and 40% through domestic generation, which grew by less than 1%. Consumption is expected to grow by approximately 2% this year. More than 31% of the total electricity requirement was covered by combined heat and power (CHP), some 27% by nuclear power, approximately 18% by hydropower, and 8% by coal and other conventional condensing power. Net imports of electricity rose to 15%, an alltime high of 11.9 billion kWh, equivalent to 15% of the electricity used m Finland. This compares to 11.1 billion kWh in 1999 and 10.7 billion kWh in 1990. Net imports of electricity rose by 6.8% last year. Imports from Sweden increased by 25%, while imports from Russia fell by 13%. Exports of electricity from Finland were low, because of inexpensive electricity available in the Nordic countries. Due to the good hydropower situation and competition, electricity prices dropped again, by approximately 1%. Electricity trading grew rapidly, with almost one-fifth of all electricity used in Finland being traded through Nord Pool

A survey on the time-temperature conditions of pasteurized milk in Greece during transportation to retail, retail storage, and domestic storage and handling was performed. The data derived from the survey were described with appropriate probability distributions and introduced into a growth model of Listeria monocytogenes in pasteurized milk which was appropriately modified for taking into account strain variability. Based on the above components, a probabilistic model was applied to evaluate the growth of L. monocytogenes during the chill chain of pasteurized milk using a Monte Carlo simulation. The model predicted that, in 44.8% of the milk cartons released in the market, the pathogen will grow until the time of consumption. For these products the estimated mean total growth of L. monocytogenes during transportation, retail storage, and domestic storage was 0.93 log CFU, with 95th and 99th percentiles of 2.68 and 4.01 log CFU, respectively. Although based on EU regulation 2073/2005 pasteurized milk produced in Greece belongs to the category of products that do not allow the growth of L. monocytogenes due to a shelf life (defined by law) of 5 days, the above results show that this shelf life limit cannot prevent L. monocytogenes from growing under the current chill chain conditions. The predicted percentage of milk cartons—initially contaminated with 1 cell/1-liter carton—in which the pathogen exceeds the safety criterion of 100 cells/ml at the time of consumption was 0.14%. The probabilistic model was used for an importance analysis of the chill chain factors, using rank order correlation, while selected intervention and shelf life increase scenarios were evaluated. The results showed that simple interventions, such as excluding the door shelf from the domestic storage of pasteurized milk, can effectively reduce the growth of the pathogen. The door shelf was found to be the warmest position in domestic refrigerators, and it was most frequently used by the

Badshah, L.; Hussain, F.; Burni, T.

2014-01-01

The study revealed that 90% of the rural people with different age group of District Tank, Pakistan depended upon firewood for catering. The total annual wood consumption for fueling by brick brewers, food sellers and domestic utilization was 18371 metric tons in this remote region. The saw machines also convert 13650 metric tons of timber wood yearly into logs and boards of various grades. The total wood consumption exceeds the quantity of wood harvested by tree fellers, farmers and wood sellers. Therefore the balance of over 13000 metric tons is sourced from neighboring forest of Tehsil Kulachi and Dera Ismail Khan. The quantity of wood removed and consumed for various purposes did not show a significant difference at (0.05) among the six locations. However student t-test showed significant difference existed in the mean annual removal and consumption of wood in the area. The study also enumerated Acacia nilotica, Tamarix aphylla, and Sueda fruticosa as the best and preferred fuel species. While Acacia nilotica, Prosopis farcta and Dalbergia sisso as the frequently used timber species in the region. The criterion of firewood and lumber consumption was very conventional like durability in blaze and opposed to termite. Consequently, it is recommended scientific vegetation conservation strategies meant at improved burning of fuel wood and maximized used of timber products as a complimentary efforts to enforced tree planting for conservation of plant resources.

Consequences of plant-chemical diversity for domestic goat food preference in Mediterranean forests

Science.gov (United States)

Baraza, Elena; Hódar, José A.; Zamora, Regino

2009-01-01

The domestic goat, a major herbivore in the Mediterranean basin, has demonstrated a strong ability to adapt its feeding behaviour to the chemical characteristics of food, selecting plants according to their nutritive quality. In this study, we determine some chemical characteristics related to plant nutritional quality and its variability among and within five tree species, these being the main components of the mountain forests of SE Spain, with the aim of determining their influence on food selection by this generalist herbivore. We analyse nitrogen, total phenols, condensed tannins and fibre concentration as an indicator of the nutritive value of the different trees. To determine the preference by the domestic goat, we performed two types of feeding-choice assays, where goats had to select between different species or between branches of the same species but from trees of different nutritional quality. The analysis of the plant nutritional quality showed significant differences in the chemical characteristics between species, and a high variability within species. However, when faced with different tree species, the domestic goat selected some of them but showed striking individual differences between goats. When selecting between trees of the same species, the goats showed no differential selection. This limited effect of chemical plant characteristics, together with the variability in foraging behaviour, resulted in a widespread consumption of diverse plant species, which can potentially modulate the effect of the goat on vegetation composition, and open the way for the conservation of traditional livestock grazing on natural protected areas.

We collected natural and sociological environmental data related to the estimation of radiation dose by radionuclides that will be released from a nuclear fuel reprocessing plant, which is now under construction in Rokkasho Village. The consumption rate of livestock feed eaten by domestic animals is an important factor for the estimation of radioactive material transfer to the animals. We surveyed the amount of livestock feed in and around Rokkasho Village by means of questionnaires to stockbreeding farmers. The questionnaires were distributed to 90 farmers who kept one of five kinds of domestic animals or poultry; milking cattle, beef cattle, hogs, broilers and laying hens. Several farming companies were also included as subjects. Recovery of the questionnaires was 59%. The hogs, broilers and laying hens were fed compound feeds consisting of imported materials. The feed for milking cattle and beef cattle consisted of grass, field corn and other concentrates. The consumption rates of grass and field corn for dairy cattle were 22.5 kg-fresh d -1 and 8.3 kg-fresh d -1 , respectively. The grass and field corn consumption rate for beef cattle were 2.8 kg-fresh d -1 and 0.3 kg-fresh d -1 , respectively. All of these rates were lower than those used for dose assessment of the reprocessing plant. (author)

Some implications of changing patterns of mineral consumption

Science.gov (United States)

Menzie, W. David; DeYoung,, John H.; Steblez, Walter G.

2003-01-01

DeYoung and Menzie (1999) examined the relations among population, Gross Domestic Product, and mineral consumption (aluminum, cement, copper, and salt) for Japan, Korea, and the United States between 1965 and 1995. They noted the extremely rapid growth of consumption in Korea between 1975 and 1995. Concomitantly, Korea's population growth rate declined. This paper extends that earlier work by examining patterns of consumption of these same commodities in the twenty most populous countries for the period 1970 through 1995. Developed countries, such as France, Germany, Japan, the United Kingdom, and the United States, show patterns of consumption that are stable (cement, copper, and salt) or grow slowly (aluminum). Some developing countries, including China, Thailand, and Turkey, show more rapid growth of consumption, especially of cement, copper, and aluminum. These changing patterns of mineral consumption in developing countries have important implications -- if they continue, there could be major increases in world mineral consumption and major increases in environmental residuals from mineral production and use. If China reaches the level of consumption of copper of developed countries, world consumption could reach levels more than twice that of 1995 (10.5 million tons).

In 1992, the gross domestic energy consumption in Italy was 167.5 MTOE (including bunkers) while in 1993 it decreased to 165.9 MTOE. The overall electricity demand passed from 244.8 TWh in 1992 to 246.6 TWh in 1993. In the same period, the overall contribution from Renewable Energy Sources (RES) kept almost constant at 5.y consumption. The RES contribution represented a share larger than gross National production of energy in 1992.

During the last years the national energy consumption of Luxembourg shifted noticeable towards the building sector. In 1990 71 % of the total domestic end energy consumption was ascribed to industrial sector and only 20 % to the building sector. The distribution changed significantly and in 2005 the energy consumption dedicated to industrial sector represented only 44 %, transport 25 % and the tertiary sector 31 % [1], which includes private and public households as well as non-residential buildings. The buildings account for 40 % of total energy consumption in the EU and there is an enormous energy saving potential. Therefore the EUdirective 2002/91/EG [2] requires from all EU Member States to save energy in this sector. Hence the energy saving of buildings present an essential part of climate protection. Furthermore the new directive 2010/31/EG [3] requires from the Member States to tighten national standards and to draw up national plans for increasing the number of nearly zero-energy buildings. But for a better understanding of energy flows in buildings and to develop energy saving concepts as well as to estimate possible energy savings of buildings a detailed analysis of energy consumption databases is an important precondition. The following field survey monitors 47 office buildings in Luxembourg. A separate gathering of electricity, heat and cooling energy consumptions allowed a detailed energetic analysis. A statistical analysis and interpretation of new buildings differentiated by energy sources as well as definition of energy relevant parameters like the window ratio, the construction method, the type of use or the kind of technical installations show the problems of typical existing office buildings. A final extrapolation to the population of all new office buildings in Luxembourg helps to estimate the energy saving potential.

Photovoltaic Self-Consumption; Autoconsumo fotovoltaico

Alonso Abella, M.; Chenlo Romero, F.

2013-02-01

This paper analyzes the photovoltaic (PV) self consumption, or the option of using photovoltaic systems connected to the electric grid for the purpose of consuming the PV generated energy in the own installation (homes, small industries, office buildings, etc.) in order to reduce the external demand and the electric bill. At this time there is a legal vacuum regarding the installation of these generation systems for self-consumption, and the PV business sector and society are calling for the establishment of a legal and economic framework. Assuming that what can be saved with a photovoltaic system for domestic self-consumption is the cost of the kWh consumed currently 15c/kWh that there are no additional charges and that the cost of the turnkey photovoltaic system currently ranges from 1.8/Wp to 2.5/Wp, the resulting amortization period would be between 8 and 11 years for the condition of annual net metering.

This paper is an analysis of the retail structure in the Republic of Croatia (sector G – 52, with respect to the origin of trading companies (domestic and foreign retailers, to their size (small, medium and large companies and to sub-sectors within a sector G – 52. The aim of this paper is to contribute to the understanding of causes underlying the foreign retailers’ expansion regarding their business success. The paper includes an analysis of the structure of household consumption in the Republic of Croatia as an important condition for the development of the retail structure. The analysis involves the indicators of domestic and foreign retailers’ business success: the turnover per one trading company and the turnover per one employee of the trading company. The comparison of these indicators for domestic and foreign retailers lead to certain differences (foreign retailers are slightly more productive than the domestic retailers and to the evaluation of the differences caused by the size of the company. Since a correlation of the size of the structure of domestic and foreign trading companies in certain sub-sectors within sector G –52 must not exist, the conclusion suggests itself in the form of a need to investigate other features of the retail structure. The research is related to the year 2001. Nevertheless, the research presented in the paper points at an inadequate adaptability of domestic retailers to the structure of demand in the Republic of Croatia as the cause of the insufficient trading success.

Economic growth and energy consumption in Algeria: a causality analysis

International Nuclear Information System (INIS)

Cherfi, S.

2011-01-01

The purpose of this study is to review the causal link in the Granger sense, between energy consumption and economic growth in Algeria, to determine its implications for economic policy. The analysis was done based on Granger static and causality tests using statistical data on per capita primary energy consumption and gross domestic product per inhabitant in Algeria, over the 1965-2008 period. The results of the survey show that there is, in Algeria, a strong link between energy consumption per inhabitant and GDP per inhabitant. The results also suggest the lack of a long term impetus (no co-integration) between energy consumption and economic growth. In addition, there is a one-way causal link between GDP and energy consumption, i.e. the prior GDP data provides a better forecast of energy consumption level, but not the contrary. In other words, GDP explains consumption, not the contrary. (author)

Nothing is known about Toxoplasma gondii prevalence in donkeys in Mexico. Meat from donkey is consumed by humans in Mexico and also exported to other countries. We sought to determine the presence of antibodies against T. gondii in 239 domestic donkeys (Equus asinus) for slaughter in Durango, Mexico using the modified agglutination test (MAT). Donkeys were sampled in four premises (trade centers) where donkeys were gather for shipment to abattoirs in other Mexican states. Antibodies to T. gondii were found in 26 (10.9%) of 239 donkeys, with MAT titers of 1:25 in 7, 1:50 in 11, 1:100 in 6, and 1:200 in 2. Seropositive donkeys were found in three (75%) of the four gathering premises studied. Seroprevalence in donkeys varied from 0% to 23.1% among gathering premises. The seroprevalence of T. gondii infection was comparable among donkeys regardless their age, sex or health status. Seropositivity to T. gondii was found in donkeys between 1 to 12 years old. Multivariate analysis showed that seropositivity to T. gondii was associated with the gathering premises (OR = 1.58; 95% CI: 1.11-2.24; P = 0.009). This is the first report of T. gondii infection in donkeys in Mexico. Results indicate that consumption of undercooked or raw meat from T. gondii-infected donkeys is potentially a source of T. gondii infection for humans.

This study investigates the long and short run relationships among carbon emissions, energy consumption and economic growth in India at the aggregated and disaggregated levels during 1971–2014. The autoregressive distributed lag model is employed for the cointegration analyses and the vector error correction model is applied to determine the direction of causality between variables. Results show that a long run cointegration relationship exists and that the environmental Kuznets curve is validated at the aggregated and disaggregated levels. Furthermore, energy (total energy, gas, oil, electricity and coal) consumption has a positive relationship with carbon emissions and a feedback effect exists between economic growth and carbon emissions. Thus, energy-efficient technologies should be used in domestic production to mitigate carbon emissions at the aggregated and disaggregated levels. The present study provides policy makers with new directions in drafting comprehensive policies with lasting impacts on the economy, energy consumption and environment towards sustainable development. - Highlights: •Relationships among carbon emissions, energy consumption and economic growth are investigated. •The EKC exists at aggregated and disaggregated levels for India. •All energy resources have positive effects on carbon emissions. •Gas energy consumption is less polluting than other energy sources in India.

Scenarios Analysis of the Energies’ Consumption and Carbon Emissions in China Based on a Dynamic CGE Model

Full Text Available This paper investigates the development trends and variation characteristics of China’s economy, energy consumption and carbon emissions from 2007 to 2030, and the impacts on China’s economic growth, energy consumption, and carbon emissions under the carbon tax policy scenarios, based on the dynamic computable general equilibrium (CGE model. The results show that during the simulation period, China’s economy will keep a relatively high growth rate, but the growth rate will slow down under the benchmark scenario. The energy consumption intensity and the carbon emissions intensity per unit of Gross Domestic Product (GDP will continually decrease. The energy consumption structure and industrial structure will gradually optimize. With the economic growth, the total energy consumption will constantly increase, and the carbon dioxide emissions are still large, and the situation of energy-saving and emission-reduction is still serious. The carbon tax is very important for energy-saving and emission-reduction and energy consumption structure optimization, and the effect of the carbon tax on GDP is small. If the carbon tax could be levied and the enterprise income tax could be reduced at the same time, the dual goals of reducing energy consumption and carbon emissions and increasing the GDP growth can be achieved. Improving the technical progress level of clean power while implementing a carbon tax policy is very meaningful to optimize energy consumption structure and reduce the carbon emissions, but it has some offsetting effect to reduce energy consumption.

Electricity Consumption Clustering Using Smart Meter Data

Directory of Open Access Journals (Sweden)

Alexander Tureczek

2018-04-01

Full Text Available Electricity smart meter consumption data is enabling utilities to analyze consumption information at unprecedented granularity. Much focus has been directed towards consumption clustering for diversifying tariffs; through modern clustering methods, cluster analyses have been performed. However, the clusters developed exhibit a large variation with resulting shadow clusters, making it impossible to truly identify the individual clusters. Using clearly defined dwelling types, this paper will present methods to improve clustering by harvesting inherent structure from the smart meter data. This paper clusters domestic electricity consumption using smart meter data from the Danish city of Esbjerg. Methods from time series analysis and wavelets are applied to enable the K-Means clustering method to account for autocorrelation in data and thereby improve the clustering performance. The results show the importance of data knowledge and we identify sub-clusters of consumption within the dwelling types and enable K-Means to produce satisfactory clustering by accounting for a temporal component. Furthermore our study shows that careful preprocessing of the data to account for intrinsic structure enables better clustering performance by the K-Means method.

Meta-Analysis of Price Elasticity for Urban Domestic Water Consumption in Iran

Directory of Open Access Journals (Sweden)

Mina Tajabadi

2018-03-01

Full Text Available Price elasticity plays a critical role in determining water tariff and its system. Many economic decision makers and researchers have estimated demand function for different cities in order to predict the associated income and price elasticity. In this research we reviewed 20 studies on urban domestic water demand function from which 63 price elasticity values were obtained. Since the price elasticity values obtained from these studies had significant statistical differences, the aim of this research is to determine the effective factors in price elasticity values as well as to analyze differences in such values using meta-analysis technique. The meta-analysis technique focuses on variation in water price elasticity results. The statistical meta-analysis technique focuses on two main objectives of publication bias or publication heterogeneity in reported results. The results indicated that publication bias is negligible while publication heterogeneity is significant. The major factors affecting price elasticity values are classified into 4 categories including theoretical, model, data and socio-geographical specifications. The result indicated that variables such as income, time-series datasets, natural logarithm function and use of stone-geary theory which is the basis for predicting many domestic water demand functions, significantly overestimate the price elasticity values. Also the geographical condition of the region, population density and use of OLS technique to estimate the demand parameters underestimates the price elasticity values.

The objective was to estimate the self-reported prevalence of domestic violence in a pregnant military population presenting for emergency care, and to determine the acceptability of domestic violence screening. A prospective observational survey of patients presenting for obstetric emergency care. Women were anonymously screened for domestic violence using the Abuse Assessment Screen. A total of 499 surveys were distributed, with 26 duplicate surveys. After excluding the 12 blank surveys, a total of 461 surveys were included in the final analysis. The lifetime prevalence of domestic violence (including physical, emotional and sexual abuse) was 22.6% (95% CI=19.0 to 26.4) with 4.1% (95% CI=2.3-6.0) of women reporting physical abuse in the past year and 2.8% (95% CI=1.3-4.3) reporting abuse since becoming pregnant. The majority of women 91.8% (95% CI=88.7-94.2) were not offended by domestic violence screening and 88.8% (95% CI=82.0-88.9) felt that patients should be routinely screened. The self-reported prevalence of domestic violence in a pregnant military population presenting for emergency care was 22.6%. Most women are not offended by domestic violence screening and support routine screening.

Maeenpaeae, Ilmo; Siikavirta, Hanne

2007-01-01

The estimation of greenhouse gas (GHG) emissions associated with international trade and final consumption gives a more complete and balanced picture of the responsibilities of various countries for the emissions that cause the climate change. The aim of this study was to look at the impact of the coverage of the GHGs and their sources and assumptions regarding the emissions of imports on the results of GHG emissions associated with international trade and final consumption of Finland. In addition to a single year study, a trend covering years 1990-2003 was produced for Finland to study the development of the GHG emissions associated with domestic consumption and the reasons behind the development. According to our results Finland was in 1999 a net exporter of CO 2 from fossil fuel combustion, CO 2 from all sources and GHGs of 4(4.2), 5 or 7 Gkg, respectively. The impact of different assumptions concerning the emissions embodied in imports in the case of Finland was tested by using the domestic emission intensities and the ratios of embodied emissions in imports in relation to domestic products by utilizing the data from the study by (OECD, 2003b. Carbon Dioxide Emissions Embodied in International Trade of Goods, STI Working Paper 2003/15, OECD, Paris). In the case of Finland, the differences of results calculated with these two methods remained rather small. The total emissions embodied in the imports changed from 33.8 to 34.4 Gkg and consequently the net export of CO 2 from fossil fuel combustion changed from 4.2 to 3.6 Gkg. The results for 1990-2003 show that the GHG emissions embodied in the exports have exceeded the GHG emissions embodied in the imports from early 1990s. The reason for the increasingly positive GHG trade balance in the case of Finland has been the change in the magnitude of trade rather than the changes in its structure. The results show also that the impact of international transport on the emission intensity of imports is significant and

Life cycle greenhouse gas emissions, consumptive water use and levelized costs of unconventional oil in North America

Science.gov (United States)

Mangmeechai, Aweewan

Conventional petroleum production in many countries that supply U.S. crude oil as well as domestic production has declined in recent years. Along with instability in the world oil market, this has stimulated the discussion of developing unconventional oil production, e.g., oil sands and oil shale. Expanding the U.S. energy mix to include oil sands and oil shale may be an important component in diversifying and securing the U.S. energy supply. At the same time, life cycle GHG emissions of these energy sources and consumptive water use are a concern. In this study, consumptive water use includes not only fresh water use but entire consumptive use including brackish water and seawater. The goal of this study is to determine the life cycle greenhouse gas (GHG) emissions and consumptive water use of synthetic crude oil (SCO) derived from Canadian oil sands and U.S. oil shale to be compared with U.S. domestic crude oil, U.S. imported crude oil, and coal-to-liquid (CTL). Levelized costs of SCO derived from Canadian oil sands and U.S. oil shale were also estimated. The results of this study suggest that CTL with no carbon capture and sequestration (CCS) and current electricity grid mix is the worst while crude oil imported from United Kingdom is the best in GHG emissions. The life cycle GHG emissions of oil shale surface mining, oil shale in-situ process, oil sands surface mining, and oil sands in-situ process are 43% to 62%, 13% to 32%, 5% to 22%, and 11% to 13% higher than those of U.S. domestic crude oil. Oil shale in-situ process has the largest consumptive water use among alternative fuels, evaluated due to consumptive water use in electricity generation. Life cycle consumptive water use of oil sands in-situ process is the lowest. Specifically, fresh water consumption in the production processes is the most concern given its scarcity. However, disaggregated data on fresh water consumption in the total water consumption of each fuel production process is not available

Consumption of potassium permanganate and total organic carbon (TOC) were investigated as indices of total organic matter migrated into water from plastic kitchen utensils, food packages and toys for children. The samples were soaked in water at 60 or 95 degrees C for 30 min for kitchen utensils and food packages, and at 40 degrees C for 30 min for toys and the eluates were examined, using the two indices. The quantitation limits were both 0.5 microg/mL. Among 97 kitchen utensils and food packages tested, consumption of potassium permanganate and TOC were 0.5-10.9 microg/mL and ND-18.9 microg/mL for polyvinyl chloride (PVC) tea-pot spouts and nylon kitchen utensils, respectively. Among 32 toys tested, the levels were 0.8-45.5 microg/mL and 0.5-8.9 microg/mL from PVC toys and block toys made by ethylene vinyl acetate resin. The levels for other samples were very low. There were large discrepancies between consumption of potassium permanganate and TOC for some PVC products and nylon kitchen utensils. The cause may be a marked difference of the oxidation decomposition rate by potassium permanganate, depending on the kind of organic matter that migrated from the plastics.

Review of the Department of Trade and Industry passive solar programme. Pt. 2: non-domestic buildings. Final report

International Nuclear Information System (INIS)

1997-06-01

The aim of the Passive Solar Programme (PSP) was to quantify the nature, size and timing of passive solar contribution to the UK building stock and the energy savings; to determine the best and most cost effective methods of achieving savings; to explore and develop better techniques; and to transfer the information to the appropriate people. There are over 1.25 million non-domestic buildings in the UK. It has been calculated that it is technically and economically possible to use passive solar design along with improved efficiency measures to reduce energy consumption in the UK by 25% in most existing non-domestic buildings and over 50% in new buildings. From the UK Government's point of view the savings are potentially very significant, and initiatives are aimed at bringing passive solar design into wide use at the earliest possible date. The PSP was intended to encourage the use of passive solar design and displace other forms of energy consumption. The earlier passive solar programme was focused on the domestic sector, where the primary concern was to reduce energy consumed in space heating. Its extension to non-domestic buildings demanded a broader definition of the potential benefits. (author)

The colon and rectum are common sites of food-related cancer in developed countries. Recent studies strongly suggest that red meat intake is associated with colon cancer, whereas for rectal cancer such an association still needs to be proved. The aim of the study was to assess the role of total amount and frequency of red meat intake in colorectal carcinogenesis based on published data using meta-analysis methods. The literature published until 2009 was selected from: MEDLINE, PubMed, Scopus, Embase, CancerLit, Google Scholar and Cochrane Library databases. The used search terms were: colorectal cancer, colon cancer, rectal cancer, meat intake, red meat intake, red meat consumption, meat consumption, colorectal cancer risk, colon cancer risk, rectal cancer risk and lifestyle. Articles investigating red meat intake of more often than once a day or 50 g per day were reviewed and selected for further analysis. Twenty-two studies fulfilled the established criteria. A meta-analysis confirmed the carcinogenic effect of the consumption of over 50 g of red meat per day for the colon (relative risk 1.21, 1.07-1.37) but not for the rectum (relative risk 1.30, 0.90-1.89). Red meat intake more frequently than once a day can induce both colonic (relative risk 1.37, 1.09-1.71) and rectal cancer (relative risk 1.43, 1.24-1.64). Red meat intake is associated with elevated risk of developing colorectal cancer. The frequency of red meat consumption rather than total amount of consumed meat is associated with a higher risk of colorectal carcinogenesis.

Efforts are exerted to develop power-efficient modules to be built into electrical products for reduction in power consumption in the standby state for domestic and office-automation appliances. In this study, television sets, audio sets, and air conditioners were selected out of domestic appliances and, out of office-automation appliances, notebook-size and desktop personal computers were selected. The standby power consumption is to be reduced to 3mW for domestic appliances, to 0.2W for notebook-size personal computers, and to 1/10-1/200 of the level being currently consumed in the case of desktop personal computers. For domestic appliances, a power efficient module not insulated from the AC power line was developed, to be built into a CPU-aided appliance to be turned on and off by remote control for the reduction of its standby power to 3mW. For notebook-size personal computers, a power-efficient power source insulated from the AC power line was developed, which consumes but 0.2W of standby power. It was built into a marketed notebook-size personal computer and tested for performance. For desktop personal computers, a 25mW power source insulated from the AC power line was fabricated, and tested for performance. (NEDO)

Full Text Available Background: Adequate hydration is a key factor for correct functioning of both cognitive and physical processes. In France, public health recommendations about adequate total water intake (TWI only state that fluid intake should be sufficient, with particular attention paid to hydration for seniors, especially during heatwave periods. The objective of this study was to calculate the total amount of water coming from food and beverages and to analyse characteristics of consumption in participants from a large French national cohort. Methods: TWI, as well as contribution of food and beverages to TWI was assessed among 94,939 adult participants in the Nutrinet-Santé cohort (78% women, mean age 42.9 (SE 0.04 using three 24-h dietary records at baseline. Statistical differences in water intakes across age groups, seasons and day of the week were assessed. Results: The mean TWI was 2.3 L (Standard Error SE 4.7 for men and 2.1 L (SE 2.4 for women. A majority of the sample did comply with the European Food Safety Authority (EFSA adequate intake recommendation, especially women. Mean total energy intake (EI was 1884 kcal/day (SE 1.5 (2250 kcal/day (SE 3.6 for men and 1783 kcal/day (SE 1.5 for women. The contribution to the total EI from beverages was 8.3%. Water was the most consumed beverage, followed by hot beverages. The variety score, defined as the number of different categories of beverages consumed during the three 24-h records out of a maximum of 8, was positively correlated with TWI (r = 0.4; and with EI (r = 0.2, suggesting that beverage variety is an indicator of higher consumption of food and drinks. We found differences in beverage consumptions and water intakes according to age and seasonality. Conclusions: The present study gives an overview of the water intake characteristics in a large population of French adults. TWI was found to be globally in line with public health recommendations.

Energy in Ghana: The dominance of transport in petroleum consumption

International Nuclear Information System (INIS)

Abeasi, K.

1991-01-01

The sustained provision of energy has long been recognized as one of the essential prerequisites for a country's socio-economic development. Until recently, a country's aggregate energy consumption was equated with its relative economic and developmental well-being, represented by the close correlation between gross domestic product (GDP) and per capita consumption of commercial energy. Although events of recent years, principally the swinging increases in petroleum prices and measures taken to improve the efficiency of energy use, have loosened the parallel equation of GDP with energy consumption, yet the position of energy as the bedrock of a country's development remains unshaken. 4 refs, 1 fig., 4 tabs

The use of fuelwood as a primary source of energy for domestic use is causing severe deforestation in Garhwal Himalaya. In the present study fuelwood consumption patterns have been studied in six villages; two each in tropical (Ganga Bhogpur and Kunow), sub-tropical (Bhainswara and Ghargoan) and temperate (Dhaulana and Chunnikhal) regions under various ecological and socio-economic conditions. The total average fuelwood consumption in the present study was observed to be highest for Ganga Bhogpur (2.52 kg per capita per day) in the tropical region, whereas, lowest for Ghargoan (1.63 kg per capita per day) in the sub-tropical region. The labour energy expenditure for fuelwood collection was greatest for Dhaulana (146.62 MJ per capita per day) in the temperate region, and lowest for Ganga Bhogpur (88.80 MJ per capita per day) in the tropical region. The fuelwood consumption rate oscillated considerably across the different seasons. The tree and shrub species preferred by the inhabitants for fuelwood were Holoptelea integrifolia, Anogeissus latifolia and Lantana camara in the tropical region; A. latifolia, Acacia catechu and Carissa spinarum in the sub-tropical region; and Quercus leucotrichophora, Myrica esculenta and Pyracantha crenulata in the temperate region, respectively.

Waste management in rural areas has become a major challenge for governments of developing countries. The success of waste management decisions directly lies in the accuracy and reliability of the data on which choices are based; many factors influence these data. Here, we examined the factors influencing domestic waste in rural areas of developing countries (RADIC), using both field surveys and by reviewing previous literature. The social factors included population, education and culture. There was a positive linear relationship between waste generation amount and population size (R 2  = 0.9405). Environmental education, training and demonstration projects played a positive role in improving people's awareness of the benefits of recycling and reducing waste. Traditional and national cultures, consumption and living habits contributed to variations in the generation and composition of domestic waste. Generally, practices related to conservation of and reverence for nature and green consumption encourage people to reduce, reuse and recycle waste in their daily life. Economic factors included household income and expenditure, energy and fuel structure, and types of industry that occurred in villages. A Kuznets inverted "U" curve relationship existed between domestic waste generation and people's income in rural areas of China. However, the waste generation rate had a linear relationship with the gross national income per capita in RADIC. The composition, bulk density and calorific value of domestic waste were variously affected by the energy and fuel structure and the types of industry that occurred. The natural factors included geography and climate (including rainfall, humidity, temperature and harvest seasons). The moisture content of waste was directly influenced by rainfall and humidity. Temperature affected waste characteristics by influencing residential heating modes. The waste characteristics were also influenced by the mixing of agricultural and

Analysis of patterns of bushmeat consumption reveals extensive exploitation of protected species in eastern Madagascar.

Directory of Open Access Journals (Sweden)

Richard K B Jenkins

Full Text Available Understanding the patterns of wild meat consumption from tropical forests is important for designing approaches to address this major threat to biodiversity and mitigate potential pathways for transmission of emerging diseases. Bushmeat consumption has been particularly poorly studied in Madagascar, one of the world's hottest biodiversity hotspots. Studying bushmeat consumption is challenging as many species are protected and researchers must consider the incentives faced by informants. Using interviews with 1154 households in 12 communes in eastern Madagascar, as well as local monitoring data, we investigated the importance of socio-economic variables, taste preference and traditional taboos on consumption of 50 wild and domestic species. The majority of meals contain no animal protein. However, respondents consume a wide range of wild species and 95% of respondents have eaten at least one protected species (and nearly 45% have eaten more than 10. The rural/urban divide and wealth are important predictors of bushmeat consumption, but the magnitude and direction of the effect varies between species. Bushmeat species are not preferred and are considered inferior to fish and domestic animals. Taboos have provided protection to some species, particularly the Endangered Indri, but we present evidence that this taboo is rapidly eroding. By considering a variety of potential influences on consumption in a single study we have improved understanding of who is eating bushmeat and why. Evidence that bushmeat species are not generally preferred meats suggest that projects which increase the availability of domestic meat and fish may have success at reducing demand. We also suggest that enforcement of existing wildlife and firearm laws should be a priority, particularly in areas undergoing rapid social change. The issue of hunting as an important threat to biodiversity in Madagascar is only now being fully recognised. Urgent action is required to ensure

Domestic outsourcing and multitasking: How much do they really contribute?

Science.gov (United States)

Sullivan, Oriel; Gershuny, Jonathan

2013-09-01

The bulk of responsibility for domestic work and childcare in heterosexual couples falls on women. But the means they find to cope with this load, and how these means relate to the factors underpinning the division of labor are not often studied. Two much-cited ways of reducing overall work time are purchasing domestic assistance (outsourcing) and the multitasking of domestic/caring tasks. Using UK 2000/2001 time-use data (N=4196 couples), we find domestic outsourcing is related to having dependent children and to partners' resources, but has little impact on the total domestic/caring workload of either partner. Nor can outsourcing account for the reduction in women's unpaid labor with increasing economic resources. Wives spend more time multitasking than husbands, but their proportion of multitasked domestic time is similar, and is not affected by resources or dependent children. Domestic multitasking seems to be more related to opportunity (time at home) than to time pressure. Copyright © 2013 Elsevier Inc. All rights reserved.

Energy consumption declined in 1993

On presenting the energy consumption figures for 1993 the Minister for Economic Affairs of Baden-Wuerttemberg Dieter Spoeri (SPD) spoke of the eternal task of saving energy. In his view the slight decline in energy consumption from 1992 to 1993 should not be interpreted as a greater willingness to save energy; its main cause is rather to be seen in the course of the economy. According to estimations, total energy consumption fell 0.5% and electricity consumption 1.0% from 1992 to 1993. The economy on the other hand, still a decisive factor in energy consumption, is estimated to have declined 3% during that period. In the ten years from 1983 to 1993 total energy consumption in the Land rose an average annual 1.8% while electricity consumption kept astride with the economy with an average annual rise 2.7%, he said.

Heating cables require about 0.6% of Swiss electricity consumption, approximately as much as all TV-sets. Most important applications are domestic hot water distribution tubing, frost protection (tubing, gutters) and industrial tubing, each requiring about 1/3. For over 10 years, self-regulating technology is standard for heating cables and offers pre-defined maintenance temperatures. To minimize electricity consumption, in most applications additional control devices (timer, temperature-/ power control) are necessary. The study could not give a general answer to whether domestic hot water distribution systems should be heated by heating cables or circulation systems. The best solution depends on the specific building circumstances. Conclusions of the technical and market analysis say that measures in different fields can transfer the saving potentials into practice: architects and designers of sanitary and electrical installations should be informed by articles in specialized magazines: the goal is either to avoid the use of heating cables or to minimize their electricity consumption, training of plumbers and electricians should treat the efficient use of heating cables. An instruction leaflet is to be created. Building owners and operators should be informed by their specialized magazines about problems with heating cables. (author)

2011-03-01

Full Text Available In order to estimate the energy consumption demand of residential buildings, this paper first discusses the status and shortcomings of current domestic energy consumption models. Then it proposes and develops a residential building energy consumption demand model based on a back propagation (BP neural network model. After that, taking residential buildings in Chongqing (P.R. China as an example, 16 energy consumption indicators are introduced as characteristics of the residential buildings in Chongqing. The index system of the BP neutral network prediction model is established and the multi-factorial BP neural network prediction model of Chongqing residential building energy consumption is developed using the Cshap language, based on the SQL server 2005 platform. The results obtained by applying the model in Chongqing are in good agreement with actual ones. In addition, the model provides corresponding approximate data by taking into account the potential energy structure adjustments and relevant energy policy regulations.

Energy consumption and economic development after the energy price increases of 1973

Danielewski, J.

1993-01-01

The interdependence between energy consumption and economic development are highlighted in this research, which focuses on energy price rises between 1973 and 1989. Three groups of countries are identified, developing and developed market economies and centrally planned economies. Two areas of interdependence are examined, firstly the dynamic relationship between primary energy consumption growth and real economic growth and secondly the static relationship between primary energy consumption and national income. In the period under review, developing market economies reacted most strongly to higher energy prices, with lower energy consumption while maintaining real growth in the Gross Domestic Product. However developing countries and centrally planned economies increased their energy consumption per unit of national income although the rate of increase slowed after 1975. (UK)

Domestic violence is an extremely underreported crime and a growing social problem in the United States. However, the true burden of the problem remains unknown. To assess the reported prevalence of domestic violence among trauma patients. A 6-year (2007-2012) retrospective analysis of the prospectively maintained National Trauma Data Bank. Trauma patients who experienced domestic violence and who presented to trauma centers participating in the National Trauma Data Bank were identified using International Classification of Diseases, Ninth Revision diagnosis codes (995.80-995.85, 995.50, 995.52-995.55, and 995.59) and E codes (E967.0-E967.9). Patients were stratified by age into 3 groups: children (≤18 years), adults (19-54 years), and elderly patients (≥55 years). Trend analysis was performed on April 10, 2014, to assess the reported prevalence of domestic violence over the years. Trauma patients presenting to trauma centers participating in the National Trauma Data Bank. To assess the reported prevalence of domestic violence among trauma patients. A total of 16 575 trauma patients who experienced domestic violence were included. Of these trauma patients, 10 224 (61.7%) were children, 5503 (33.2%) were adults, and 848 (5.1%) were elderly patients. The mean (SD) age was 15.9 (20.6), the mean (SD) Injury Severity Score was 10.9 (9.6), and 8397 (50.7%) were male patients. Head injuries (46.8% of patients) and extremity fractures (31.2% of patients) were the most common injuries. A total of 12 515 patients (75.1%) were discharged home, and the overall mortality rate was 5.9% (n = 980). The overall reported prevalence of domestic violence among trauma patients was 5.7 cases per 1000 trauma center discharges. The prevalence of domestic violence increased among children (14.0 cases per 1000 trauma center discharges in 2007 to 18.5 case per 1000 trauma center discharges in 2012; P = .001) and adults (3.2 cases per 1000 discharges in 2007 to 4.5 cases per

Highlights: • An MILP model is formulated for energy consumption scheduling in a smart building. • Domestic appliances from multiple smart homes are considered. • Equipment operation and power consumption tasks starting time are scheduled. • Results from two examples indicate cost savings and power peak reduction. • Peak demand charge scheme is adopted to reduce the peak demand from grid. - Abstract: Microgrid works as a local energy provider for domestic buildings to reduce energy expenses and gas emissions by utilising distributed energy resources (DERs). The rapid advances in computing and communication capabilities enable the concept smart buildings become possible. Most energy-consuming household tasks do not need to be performed at specific times but rather within a preferred time. If these types of tasks can be coordinated among multiple homes so that they do not all occur at the same time yet still satisfy customers’ requirement, the energy cost and power peak demand could be reduced. In this paper, the optimal scheduling of smart homes’ energy consumption is studied using a mixed integer linear programming (MILP) approach. In order to minimise a 1-day forecasted energy consumption cost, DER operation and electricity-consumption household tasks are scheduled based on real-time electricity pricing, electricity task time window and forecasted renewable energy output. Peak demand charge scheme is also adopted to reduce the peak demand from grid. Two numerical examples on smart buildings of 30 homes and 90 homes with their own microgrid indicate the possibility of cost savings and electricity consumption scheduling peak reduction through the energy consumption and better management of DER operation

The effect of taxation on tobacco consumption and public revenues in Lebanon.

Science.gov (United States)

Salti, Nisreen; Chaaban, Jad; Nakkash, Rima; Alaouie, Hala

2015-01-01

Tobacco consumption rates in Lebanon are among the highest worldwide. The country ratified the Framework Convention on Tobacco Control in 2005. A law was passed in 2011 which regulates smoking in closed public spaces, bans advertising, and stipulates larger warnings. Despite international evidence confirming that increasing taxation on tobacco products lowers tobacco consumption, no such policy has yet been adopted: a cigarette pack costs on average US$1.50. To date no studies in Lebanon have addressed the welfare and public finance effects of increasing taxes on tobacco products. Using the 2005 national survey of household living conditions, we estimate an almost ideal demand system to generate price elasticities of demand for tobacco. Using estimated elasticities and a conservative scenario for expected smuggling, we simulate the consumption and tax revenue effects of a change in the price of tobacco under various tax schemes. Increasing taxes on all tobacco products so as to double the price of imported cigarettes would lower their consumption by 7% and consumption of domestically produced cigarettes by over 90%. Young adults (ages 15-30) are more sensitive: consumption would drop by 9% for imported cigarettes and by 100% for domestic cigarettes. Government revenues would increase by approximately 52%. The estimated elasticities indicate that an increase in taxes on all tobacco products would lead to a reduction in consumption and an increase in government revenue. Evidence from Lebanon on the effectiveness of increased taxation may help initiate national debate on the need to raise taxes. Published by the BMJ Publishing Group Limited.

The goal of this paper is to model the relationship between electricity consumption and real gross domestic product (GDP) for Malaysia in a bivariate and multivariate framework. We use time series data for the period 1971-2003 and apply the bounds testing approach to search for a long-run relationship. Our results reveal that electricity consumption, real GDP and price share a long-run relationship. The results of the autoregressive distributed lag (ARDL) estimates of long-run elasticity of electricity consumption on GDP are found to be around 0.7 and statistically significant. Finally, in the short-run, the results of the causality test show that there is a unidirectional causal flow from electricity consumption to economic growth in Malaysia. From these findings we conclude that Malaysia is an energy-dependent country, leading us to draw some policy implications. This paper adds support and validity, thus reducing the policy makers concern on the ambiguity of the electricity and growth nexus in Malaysia. (author)

This study was carried out in Bulamogi, Uganda, with the main objective of determining preferred firewood species, their harvesting and consumption patterns. Data collected through household and key-informants interviews, using open- and close-ended questionnaires and semi-structured interviews, showed that 48 plant species in 36 genera and 20 families are used as firewood. These plants have other uses as herbal medicines and in traditional cultural rites. There is almost total dependence on firewood for domestic cooking and small-scale industries. Firewood is used to fire bricks (55%), distil spirits (26%), cure fish (10%), cook food in restaurants (6%) and to produce charcoal (3%). Firewood for domestic use is collected mainly by women, and largely comprises of dead wood. The distances travelled to firewood collection areas are short and little time is spent. The harvesting of firewood for domestic use may have a lower direct impact on the native flora, than the harvesting of fuelwood for commercial use by small-scale industries and to make charcoal, which requires large amounts of wood that is often green. According to the community response, firewood is abundant but declining. This decline may be related to increasing demands generated by the growing human population of Bulamogi, and growing national need for charcoal. Cultural taboos that have hitherto played an important role in plant conservation appear to be weakening. There is limited trading of firewood in the community. (author)

In order to reduce the energy consumption and membrane fouling of the conventional membrane bioreactor (MBR), a kind of low energy consumption vortex wave flow MBR was exploited based on the combination of biofilm process and membrane filtration process, as well as the vortex wave flow technique. The experimental results showed that the vortex wave flow state in the membrane module could be formed when the Reynolds number (Re) of liquid was adjusted between 450 and 1,050, and the membrane flux declined more slowly in the vortex wave flow state than those in the laminar flow state and turbulent flow state. The MBR system was used to treat domestic wastewater under the condition of vortex wave flow state for 30 days. The results showed that the removal efficiency for CODcr and NH 3 -N was 82% and 98% respectively, and the permeate quality met the requirement of 'Water quality standard for urban miscellaneous water consumption (GB/T 18920-2002)'. Analysis of the energy consumption of the MBR showed that the average energy consumption was 1.90 ± 0.55 kWh/m 3 (permeate), which was only two thirds of conventional MBR energy consumption.

Impact of domestic and tertiary buildings heating by natural gas in the Italian context

International Nuclear Information System (INIS)

Aste, Niccolò; Del Pero, Claudio

2012-01-01

Natural Gas (NG) is commonly used for satisfying population needs for heating, domestic hot water production and cooking, particularly in countries where the price of electricity is high. Typically, NG is extensively distributed on urbanized territory and can be exploited by using different technologies. As a consequence, primary energy is usually consumed directly in buildings, allowing high efficiency conversion but also producing pollutants in urban areas. In this paper a comprehensive analysis on NG use in the Italian domestic and tertiary building sector has been carried out, in order to evaluate energy and environmental impact of this fuel on different climatic and geographical contexts, also considering the temporal fluctuation of consumption. The aim of the work is to trace a reliable and up-to-date scenario of NG employment for building heating in Italy, which is one of the EU countries where this source is more widely used. The study was carried out under the research program “Analysis and evaluation of the current status of the reduction measures of environmental impacts due to heating energy consumption in Italy”, funded by the Italian Ministry of Environment. The data presented are an essential basis for the development of building energy efficiency and consumption rationalization policies. - Highlights: ► Detailed assessment of natural gas consumption and emission for residential and tertiary buildings heating in Italy. ► Estimation of the average specific primary energy consumption for households heating in different climatic contexts. ► Nationwide, it is the first study on the whole country with this level of detail.

High-resolution stochastic integrated thermal–electrical domestic demand model

McKenna, Eoghan; Thomson, Murray

2016-01-01

Highlights: • A major new version of CREST’s demand model is presented. • Simulates electrical and thermal domestic demands at high-resolution. • Integrated structure captures appropriate time-coincidence of variables. • Suitable for low-voltage network and urban energy analyses. • Open-source development in Excel VBA freely available for download. - Abstract: This paper describes the extension of CREST’s existing electrical domestic demand model into an integrated thermal–electrical demand model. The principle novelty of the model is its integrated structure such that the timing of thermal and electrical output variables are appropriately correlated. The model has been developed primarily for low-voltage network analysis and the model’s ability to account for demand diversity is of critical importance for this application. The model, however, can also serve as a basis for modelling domestic energy demands within the broader field of urban energy systems analysis. The new model includes the previously published components associated with electrical demand and generation (appliances, lighting, and photovoltaics) and integrates these with an updated occupancy model, a solar thermal collector model, and new thermal models including a low-order building thermal model, domestic hot water consumption, thermostat and timer controls and gas boilers. The paper reviews the state-of-the-art in high-resolution domestic demand modelling, describes the model, and compares its output with three independent validation datasets. The integrated model remains an open-source development in Excel VBA and is freely available to download for users to configure and extend, or to incorporate into other models.

During 1979-1980 acute fibrinopurulent bronchopneumonia resulted in high mortality or total loss of herds of bighorn sheep (Ovis canadensis) in California and Washington. Contact with domestic sheep occurred shortly before the onset of disease in each case. Circumstantial evidence indicated that the apparently healthy domestic sheep transmitted pathogenic bacteria to the bighorns, resulting in mortality. Pasteurella multocida and Corynebacterium pyogenes were isolated from pulmonary tissue of dead bighorns. The presence of domestic sheep may have been an important stress which initiated or compounded the disease.

Domestic and Foreign Banks’ Profitability: Differences and Their Determinants

Full Text Available The purpose of this study to analyze and compare the profitability of domestic (Public & Private and foreign banks operating in the Pakistan Banking market between 2004 and 2010 on quarterly basis. Total 36 Commercial Banks of Pakistani Industry have represented our sample. To control for the effect of bank ownership on performance, we split the sample into three categories: (1 domestic banks with Government Control, (2 domestic banks with Private control, and (3 foreign banks. This study also finds that foreign banks are more profitable than all domestic banks regardless of their ownership structure by applying regression analysis. This may suggest that it is better for a multinational bank to establish a subsidiary/branch rather than acquiring an “existing player” in the host country. We also found that domestic and foreign banks have different profitability determinants, i.e. factors that are important in shaping domestic banks’ profitability are not necessary important for the foreign banks and vice versa. Empirical results show that foreign banks are less affected by the macroeconomic factors of the host country than domestic banks and they have a higher profitability margin in Pakistan.

Full Text Available The common sources of water pollution in Malaysia are domestic sewage and industrial waste. Therefore, domestic wastewater quality effluent should be improved before discharged through the outlets. The alternative method of treatment uses microalgae for water remediation which is known as phycoremediation was applied. This technique is to remove or reduce nutrients and harmful pollutants in domestic wastewater. Thus, objective of the present study is to bioremediate the physiochemical and heavy metal from domestic wastewater using freshwater green microalgae Botryococcus sp. A photobioreactor is used to treat the wastewater by employing the microalgae Botryococcus sp. as a vital part of the treatment system. The results show that several nutrients have been reduced successfully such as phosphate and total phosphorus of 100% removal, inorganic carbon of 99% removal, total carbon of 42% removal, and nitrate of 10%. The most prominent heavy metal content that has been removed is Aluminium of 41%. At the same time, the growth of microalgae Botryococcus sp. in this wastewater has achieved the maximum value at Day 4 with 2.58 × 105 cell/ml only. These results show the potential of Botryococcus sp. cultivation as an alternative method to treat domestic wastewater and any other biotechnology works in the future.

This study attemps to investiagte the causal relationship between oil consumption and economic growth in Malaysia where oil consumption and real gross domestic product have been rapidly increased in recent years. To this end, the study employs annual data covering the period 1965–2011. Tests for unit roots, co-integration, and Granger-causality based on the error-correction models are presented. The overall results support the existence of bi-directional causality between oil consumption and economic growth in Malaysia. This means that an increase in oil consumption directly affect economic growth. Thus, in order not to make an adverse effect on economic growth, Malaysia should endeavor to overcome the constraints on oil consumption. Moreover, it appears that economic growth induces oil consumption. - Highlights: • We examine the causality between oil consumption and economic growth in Malaysia. • We employed the annual data covering the period 1965–2011. • We estimated error-correction models to test for the direction of causality. • We found that there is bi-directional causality between the two

The U.S. employment effects of military and domestic spending priorities.

This study focuses on the employment effects of military spending versus alternative domestic spending priorities. The authors begin by introducing the basic input-output modeling technique for considering issues such as these in a systematic way. They then present some simple alternative spending scenarios-namely, devoting $1 billion to the military versus the same amount of money spent for five alternatives: tax cuts that produce increased levels of personal consumption; health care; education; mass transit; and construction targeted at home weatherization and infrastructure repair. The first conclusion in assessing such relative employment effects is straightforward: $1 billion spent on personal consumption, health care, education, mass transit, and construction for home weatherization/infrastructure will all create more jobs in the U.S. economy than would the same $1 billion spent on the military. The authors then examine the pay level of jobs created through these alternative spending priorities and assess the overall welfare effects of the alternative employment outcomes. Combining these alternative domestic spending categories in an effective way can also generate a higher level of compensation for working people in the United States and a better average quality ofjobs.

Equivalent electricity storage capacity of domestic thermostatically controlled loads

International Nuclear Information System (INIS)

Sossan, Fabrizio

2017-01-01

A method to quantify the equivalent storage capacity inherent the operation of thermostatically controlled loads (TCLs) is developed. Equivalent storage capacity is defined as the amount of power and electricity consumption which can be deferred or anticipated in time with respect to the baseline consumption (i.e. when no demand side event occurs) without violating temperature limits. The analysis is carried out for 4 common domestic TCLs: an electric space heating system, freezer, fridge, and electric water heater. They are simulated by applying grey-box thermal models identified from measurements. They describe the heat transfer of the considered TCLs as a function of the electric power consumption and environment conditions. To represent typical TCLs operating conditions, Monte Carlo simulations are developed, where models inputs and parameters are sampled from relevant statistical distributions. The analysis provides a way to compare flexible demand against competitive storage technologies. It is intended as a tool for system planners to assess the TCLs potential to support electrical grid operation. In the paper, a comparison of the storage capacity per unit of capital investment cost is performed considering the selected TCLs and two grid-connected battery storage systems (a 720 kVA/500 kWh lithium-ion unit and 15 kVA/120 kWh Vanadium flow redox) is performed. - Highlights: • The equivalent storage capacity of domestic TCLs is quantified • A comparison with battery-based storage technologies is performed • We derive metrics for system planners to plan storage in power system networks • Rule-of-thumb cost indicators for flexible demand and battery-based storage

Many scholars have shown their interest into the relationship between energy consumption (EC), gross domestic product (GDP) and emissions. The main objective of this study is to investigate the relationship between GDP, EC and CO2 within multivariate model by using panel data method in Asian countries; Korea, Malaysia, Japan and China for annually data during the period 1960 to 2010. The main finding shows that CO2 can be explained more than 86% & 78% by EC and GDP in each of cross section model and period model respectively. As a result of that, CO2 emissions should be considered as an important factor in energy consumption and gross domestic product by policy maker.

A study on the purely domestic wastewater from Cordoba city (Abril to july 2003) has found a pollutant loading very high on these domestic wastewaters, by showing mean values of suspended solid, BOD{sub 5} and COD equal to respectively 452 mg/l, 505 mg/1 and 793 mg/l. This pollutants power probably emanates from the products for domestic cleaning used in our homes and must be associated to chemicals as citrates, oxalates, surfactants, polialcohols, organics complexing, ammonium compounds..., which show high value of pollutant loading up to 200 mg/l of BOD{sub 5} per ml of product have been measured on a commercial domestic dishwasher, and 9.000 mg/l of DQO for a domestic smoothing. Furthermore, the increasing use of pre-cooked foods can add to domestic wastewater fats, oils, and flours which can also increase the BOD:5 and COD values of these effluents. On the other hand, the measured pollutant loading or domestic wastewater from monofamily homes has been lower than those from multifamily buildings. Finally, due to the fact that the Golondrina's WWTP (Cordoba, 1991) was designed for treat values of suspended solids, BOD, and COD lower than those actually detected, its treatment processes should be probably modified in a near future.

To investigate the effect of fast food consumption on mean population body mass index (BMI) and explore the possible influence of market deregulation on fast food consumption and BMI. The within-country association between fast food consumption and BMI in 25 high-income member countries of the Organisation for Economic Co-operation and Development between 1999 and 2008 was explored through multivariate panel regression models, after adjustment for per capita gross domestic product, urbanization, trade openness, lifestyle indicators and other covariates. The possible mediating effect of annual per capita intake of soft drinks, animal fats and total calories on the association between fast food consumption and BMI was also analysed. Two-stage least squares regression models were conducted, using economic freedom as an instrumental variable, to study the causal effect of fast food consumption on BMI. After adjustment for covariates, each 1-unit increase in annual fast food transactions per capita was associated with an increase of 0.033 kg/m2 in age-standardized BMI (95% confidence interval, CI: 0.013-0.052). Only the intake of soft drinks--not animal fat or total calories--mediated the observed association (β: 0.030; 95% CI: 0.010-0.050). Economic freedom was an independent predictor of fast food consumption (β: 0.27; 95% CI: 0.16-0.37). When economic freedom was used as an instrumental variable, the association between fast food and BMI weakened but remained significant (β: 0.023; 95% CI: 0.001-0.045). Fast food consumption is an independent predictor of mean BMI in high-income countries. Market deregulation policies may contribute to the obesity epidemic by facilitating the spread of fast food.

2015-01-01

Many countries are rolling out smart electricity meters. These measure a home's total power demand. However, research into consumer behaviour suggests that consumers are best able to improve their energy efficiency when provided with itemised, appliance-by-appliance consumption information. Energy disaggregation is a computational technique for estimating appliance-by-appliance energy consumption from a whole-house meter signal. To conduct research on disaggregation algorithms, researchers require data describing not just the aggregate demand per building but also the 'ground truth' demand of individual appliances. In this context, we present UK-DALE: an open-access dataset from the UK recording Domestic Appliance-Level Electricity at a sample rate of 16 kHz for the whole-house and at 1/6 Hz for individual appliances. This is the first open access UK dataset at this temporal resolution. We recorded from five houses, one of which was recorded for 655 days, the longest duration we are aware of for any energy dataset at this sample rate. We also describe the low-cost, open-source, wireless system we built for collecting our dataset.

Effect of thyroxine on cellular oxygen-consumption and glucose uptake: evidence of an effect of total T4 and not "free T4"

DEFF Research Database (Denmark)

Kvetny, J; Matzen, L E

1990-01-01

Recent studies of cellular T4 and T3 uptake have indicated active transport of the hormones into the cell rather than passive diffusion of the non-protein bound fraction. In order to study the significance of the extracellular environment, oxygen consumption and glucose uptake were examined...... in human mononuclear blood cells. Cells were incubated in protein free medium and in human serum totally depleted of thyroid hormones by resin treatment and fixed amounts of T4 (total T4 = 0-50-100-5000 nmol/l; free T4 = 0-5-11-5600 pmol/l) were added. Thyroxine stimulated glucose uptake and oxygen......-consumption in a dose dependent manner but the T4 stimulation was dependent on the total concentration of T4 and did not differ between serum incubation or non-protein containing medium. Addition of ANS (100 mg/l) which inhibits binding of T4 to TBG, did not increase T4 effect in serum. Inhibition of the Na...

A study was conducted in which the main determinants of electricity demand in Thailand were investigated. Time-series analysis methods were used, notably the unit root test, the Johansen co-integration test and an error correction model (ECM). The objective was to determine the factors affecting short and long-run electricity consumption. This paper presented annual time series data from 1971 to 2006. The unit root test revealed that all series are non-stationary. The Johansen co-integration test revealed the co-integration between variables and the existence of the long-term relationship between them. Electricity consumption accelerated with the increase in gross domestic product (GDP) and population. In contrast, an increase in commodity price would reduce electricity consumption. The coefficient of population indicated that an increase of 1 million in total population would result in an increase in electricity consumption of 0.099 per cent. Last, the results of ECM revealed that nearly 21 per cent of long-term disequilibrium is adjusted to the current period. The factors that affect electricity consumption include GDP growth, inflation rate and population growth. It was concluded that Thailand should prepare for additional power generation from clean energy sources such as solar, biomass and wind energy. Thailand's Energy Policy and Planning Office revealed that electricity consumption in 2008 would be over 130,000 GWh with per capita consumption at nearly 2,000 kWh. The power peak demand will be nearly 24,000 MW in 2008. This result was based on the forecasting model that considered only GDP growth. However, electricity consumption depends not only on the GDP growth, but also upon the other key variables such as population, electricity selling price, consumer price index and temperature. 17 refs., 5 tabs., 4 figs.

Aebischer, B.; Huser, A.

2001-01-01

This article discusses the effect of the networking of the various devices to be found in the average home and the trend towards increased electricity consumption that will be brought about by 'intelligent' houses. Different scenarios for the increase in electricity consumption due to the increased use of multimedia systems - from the personal computer and mobile phones to hi-fi systems and the Internet are discussed. The contrasting tendencies noted in this area - such as, for example, the use of electricity to operate systems that are used to optimise and thus reduce electricity consumption in general are also discussed. Also, indirect energy-reduction effects in other areas - such as traffic reduction as a result of tele-working - are examined. Results of simulations and prognoses made concerning future trends for the electricity consumption of the various devices in homes are presented and recommendations are made on how to keep electricity consumption low when networking domestic apparatus

A longitudinal analysis of bone microstructure in postmenopausal women of the Geneva Retirees Cohort indicates that age-related cortical bone loss is attenuated at non-bearing bone sites in fermented dairy products consumers, not in milk or ripened cheese consumers, independently of total energy, calcium, or protein intakes. Fermented dairy products (FDP), including yogurts, provide calcium, phosphorus, and proteins together with prebiotics and probiotics, all being potentially beneficial for bone. In this prospective cohort study, we investigated whether FDP, milk, or ripened cheese consumptions influence age-related changes of bone mineral density (BMD) and microstructure. Dietary intakes were assessed at baseline and after 3.0 ± 0.5 years with a food frequency questionnaire in 482 postmenopausal women enrolled in the Geneva Retirees Cohort. Cortical (Ct) and trabecular (Tb) volumetric (v) BMD and microstructure at the distal radius and tibia were assessed by high-resolution peripheral quantitative computerized tomography, in addition to areal (a) BMD and body composition by dual-energy X-ray absorptiometry, at the same time points. At baseline, FDP consumers had lower abdominal fat mass and larger bone size at the radius and tibia. Parathyroid hormone and β-carboxyterminal cross-linked telopeptide of type I collagen levels were inversely correlated with FDP consumption. In the longitudinal analysis, FDP consumption (mean of the two assessments) was associated with attenuated loss of radius total vBMD and of Ct vBMD, area, and thickness. There was no difference in aBMD and at the tibia. These associations were independent of total energy, calcium, or protein intakes. For other dairy products categories, only milk consumption was associated with lower decrease of aBMD and of failure load at the radius. In this prospective cohort of healthy postmenopausal women, age-related Ct bone loss was attenuated at non-bearing bone sites in FDP consumers, not in milk

Theories of practice - new inspiration for ecological economic studies on consumption

2009-01-01

The dynamics behind ever-increasing consumption have long been a core issue of ecological economics. Studies on this topic have traditionally drawn not only on insights from economics, but also from such disciplines as sociology, anthropology and psychology. In recent years, a practice theory...... approach has emerged in sociological consumption studies, as part of a general wave of renewed interest in practice theory emanating from a desire to move beyond such dominant dualisms as the structure-actor opposition in sociology. The purpose of this paper is to introduce the practice theory approach...... in relation to studies of everyday life, domestic practices and consumption, and to argue that this approach can be fruitful for ecological economics and other fields interested in the environmental aspects of consumption. The paper emphasizes the immense challenge involved in promoting sustainable...

2014-01-01

While most of previous studies on China's energy conservation took the huge country as a whole, this manuscript revealed the obvious regional disparities in energy consumption of China's 30 provinces. Based on a hybrid energy input–output model, the total energy consumption of different regions was decomposed and compared using three measurements of embodied energy in inter-regional trade: 1) only considered inter-regional energy trade; 2) considered embodied energy in flow-out of final goods and services; 3) considered embodied energy in flow-in of final goods and services. Based on the second and third measurements, the 30 regions were categorized into four groups by their energy intensity and per capita GDP (gross domestic production). Common characteristics of decomposed regional energy intensity are discussed, and policy implication for regional energy conservation is provided. For developed regions with low energy intensities, such as Shanghai, energy conservation should focus on promoting low energy-consuming life style. For under-developed regions with low energy intensities, such as Guangxi, economic development is more urgent than energy conservation. For developing and energy absorbing regions, improving energy efficiency in industries is significant. For developing and energy exporting regions, transforming primary energy into high value-added products would be beneficial for economic development and energy conservation. - Highlights: • A hybrid input–output model for the decomposition of regional energy consumption. • A discussion of China's regional disparities in energy consumption by model results. • Regional energy consumption was compared by three measurements of embodied energy. • 30 regions of China were categorized into four groups by energy intensity and GDP

The energy consumption of supercomputers is one of the critical problems for the upcoming Exascale supercomputing era. The awareness of power and energy consumption is required on both software and hardware side. This paper deals with the energy consumption evaluation of the Finite Element Tearing and Interconnect (FETI) based solvers of linear systems, which is an established method for solving real-world engineering problems. We have evaluated the effect of the CPU frequency on the energy consumption of the FETI solver using a linear elasticity 3D cube synthetic benchmark. In this problem, we have evaluated the effect of frequency tuning on the energy consumption of the essential processing kernels of the FETI method. The paper provides results for two types of frequency tuning: (1) static tuning and (2) dynamic tuning. For static tuning experiments, the frequency is set before execution and kept constant during the runtime. For dynamic tuning, the frequency is changed during the program execution to adapt the system to the actual needs of the application. The paper shows that static tuning brings up 12% energy savings when compared to default CPU settings (the highest clock rate). The dynamic tuning improves this further by up to 3%.

Beverage consumption habits “24/7” among British adults: association with total water intake and energy intake

Science.gov (United States)

2013-01-01

Background Various recommendations exist for total water intake (TWI), yet it is seldom reported in dietary surveys. Few studies have examined how real-life consumption patterns, including beverage type, variety and timing relate to TWI and energy intake (EI). Methods We analysed weighed dietary records from the National Diet and Nutrition Survey of 1724 British adults aged 19–64 years (2000/2001) to investigate beverage consumption patterns over 24 hrs and 7 days and associations with TWI and EI. TWI was calculated from the nutrient composition of each item of food and drink and compared with reference values. Results Mean TWI was 2.53 L (SD 0.86) for men and 2.03 L (SD 0.71) for women, close to the European Food Safety Authority “adequate Intake” (AI) of 2.5 L and 2 L, respectively. However, for 33% of men and 23% of women TWI was below AI and TWI:EI ratio was Beverages accounted for 75% of TWI. Beverage variety was correlated with TWI (r 0.34) and more weakly with EI (r 0.16). Beverage consumption peaked at 0800 hrs (mainly hot beverages/ milk) and 2100 hrs (mainly alcohol). Total beverage consumption was higher at weekends, especially among men. Overall, beverages supplied 16% of EI (men 17%, women 14%), alcoholic drinks contributed 9% (men) and 5% (women), milk 5-6%, caloric soft drinks 2%, and fruit juice 1%. In multi-variable regression (adjusted for sex, age, body weight, smoking, dieting, activity level and mis-reporting), replacing 100 g of caloric beverages (milk, fruit juice, caloric soft drinks and alcohol) with 100 g non-caloric drinks (diet soft drinks, hot beverages and water) was associated with a reduction in EI of 15 kcal, or 34 kcal if food energy were unchanged. Using within-person data (deviations from 7-day mean) each 100 g change in caloric beverages was associated with 29 kcal change in EI or 35 kcal if food energy were constant. By comparison the calculated energy content of caloric drinks consumed was

Analysis and Optimization of Building Energy Consumption

Science.gov (United States)

Chuah, Jun Wei

Energy is one of the most important resources required by modern human society. In 2010, energy expenditures represented 10% of global gross domestic product (GDP). By 2035, global energy consumption is expected to increase by more than 50% from current levels. The increased pace of global energy consumption leads to significant environmental and socioeconomic issues: (i) carbon emissions, from the burning of fossil fuels for energy, contribute to global warming, and (ii) increased energy expenditures lead to reduced standard of living. Efficient use of energy, through energy conservation measures, is an important step toward mitigating these effects. Residential and commercial buildings represent a prime target for energy conservation, comprising 21% of global energy consumption and 40% of the total energy consumption in the United States. This thesis describes techniques for the analysis and optimization of building energy consumption. The thesis focuses on building retrofits and building energy simulation as key areas in building energy optimization and analysis. The thesis first discusses and evaluates building-level renewable energy generation as a solution toward building energy optimization. The thesis next describes a novel heating system, called localized heating. Under localized heating, building occupants are heated individually by directed radiant heaters, resulting in a considerably reduced heated space and significant heating energy savings. To support localized heating, a minimally-intrusive indoor occupant positioning system is described. The thesis then discusses occupant-level sensing (OLS) as the next frontier in building energy optimization. OLS captures the exact environmental conditions faced by each building occupant, using sensors that are carried by all building occupants. The information provided by OLS enables fine-grained optimization for unprecedented levels of energy efficiency and occupant comfort. The thesis also describes a retrofit

Economic growth could be influenced by different factors. In this study was analyzed the economic growth based on the electricity consumption form different sources. As economic growth indicator gross domestic product (GDP) was used. ANFIS (adaptive neuro fuzzy inference system) methodology was applied to determine the most important factors from the given set for the GDP growth prediction. Six inputs were used: electricity production from coal, hydroelectric, natural gas, nuclear, oil and renewable sources. Results shown that the electricity consumption from renewable sources has the highest impact on the economic or GDP growth prediction.

Cooling performance of R510A in domestic water purifiers

International Nuclear Information System (INIS)

Park, Ki Jung; Lee, Yo Han; Jung, Dong Soo

2010-01-01

Cooling performance of R510A is examined both numerically and experimentally in an effort to replace HFC134a in the refrigeration system of domestic water purifiers. Although the use of HFC134a is currently dominant, it is being phased out in Europe and most developed countries due to its high potential contribution to global warming. To solve this problem, cycle simulation and experimental measurements are conducted with a new refrigerant mixture of 88%RE170/12%R600a using actual domestic water purifiers. This mixture has been recently numbered and listed as R510A by ASHRAE. Test results show that, due to the small internal volume of the refrigeration system of the domestic water purifiers, system performance with R510A is greatly influenced by the amount of charge. With the optimum charge amount of 20 to 21 g, approximately 50% that of HFC134a, the energy consumption of R510A is 22.3% lower than that of HFC134a. The compressor discharge temperature of R510A is 3.7 .deg. C lower than that of HFC134a at the optimum charge. Overall, R510A, a new, long term, and environmentally safe refrigerant, is a good alternative for HFC134a. Furthermore, it requires only minor changes in the refrigeration system of the domestic water purifiers

The effect of inter-annual variability of consumption, production, trade and climate on crop-related green and blue water footprints and inter-regional virtual water trade: A study for China (1978-2008).

Previous studies into the relation between human consumption and indirect water resources use have unveiled the remote connections in virtual water (VW) trade networks, which show how communities externalize their water footprint (WF) to places far beyond their own region, but little has been done to understand variability in time. This study quantifies the effect of inter-annual variability of consumption, production, trade and climate on WF and VW trade, using China over the period 1978-2008 as a case study. Evapotranspiration, crop yields and green and blue WFs of crops are estimated at a 5 × 5 arc-minute resolution for 22 crops, for each year in the study period, thus accounting for climate variability. The results show that crop yield improvements during the study period helped to reduce the national average WF of crop consumption per capita by 23%, with a decreasing contribution to the total from cereals and increasing contribution from oil crops. The total consumptive WFs of national crop consumption and crop production, however, grew by 6% and 7%, respectively. By 2008, 28% of total water consumption in crop fields in China served the production of crops for export to other regions and, on average, 35% of the crop-related WF of a Chinese consumer was outside its own province. Historically, the net VW within China was from the water-rich South to the water-scarce North, but intensifying North-to-South crop trade reversed the net VW flow since 2000, which amounted 6% of North's WF of crop production in 2008. South China thus gradually became dependent on food supply from the water-scarce North. Besides, during the whole study period, China's domestic inter-regional VW flows went dominantly from areas with a relatively large to areas with a relatively small blue WF per unit of crop, which in 2008 resulted in a trade-related blue water loss of 7% of the national total blue WF of crop production. The case of China shows that domestic trade, as governed by

Power Consumption Estimation Using Artificial Neural Networks: The Case of Turkey

Directory of Open Access Journals (Sweden)

Havva Hilal Metin

2018-06-01

Full Text Available A significant proportion of the world energy consumption is by developing countries. As a developing country, Turkey is one of the leading countries in terms of the increase in energy demand. According to the data from the Ministry of Energy and Natural Resources, Turkey is the country with the greatest increase in demand after China in electricity and natural gas consumption since 2000. In 1970, the ratio of total energy production to consumption in Turkey was 76%. In year 2000, this ratio dropped down to 35%, in year 2010 to 26% and predicted to come down to 23% by year 2020. This situation indicates an increase in Turkey’s energy dependency every passing year and the need to implement solutions to reduce this dependency. Today, electric energy has become a very critical and indispensable part of the development of technology. Production and consumption of electrical energy, which facilitates human life and increases labour productivity, are increasing every year. Electricity is a versatile and easily controlled form of energy. Electricity is practically non-existent and non-polluting at the point of use. Electricity can be cleanly produced by completely renewable methods such as wind, water and sunlight at the production point. Electricity market has a unique feature compared to other commodities. This feature requires the consumption of electricity when it is produced. Forecasting the future consumption of electricity in Turkey is crucial in making strategic plans for the future and taking the necessary measures. In Turkey, the consumption of electricity in the estimation studies were generally observed that the use of long-term electricity consumption prediction method of neural networks. In some studies, the results obtained by artificial neural network method are compared with Box-Jenkins models and regression technique. As a result of comparison, artificial neural networks seem to be a good predictor of electricity consumption. In this

There is evidence that the adverse consequences of alcohol impose a substantial economic burden on societies worldwide. Given the lack of generalizability of study results across different settings, many attempts have been made to estimate the economic costs of alcohol for various settings; however, these have mostly been confined to industrialized countries. To our knowledge, there are a very limited number of well-designed studies which estimate the economic costs of alcohol consumption in developing countries, including Thailand. Therefore, this study aims to estimate these economic costs, in Thailand, 2006. This is a prevalence-based, cost-of-illness study. The estimated costs in this study included both direct and indirect costs. Direct costs included health care costs, costs of law enforcement, and costs of property damage due to road-traffic accidents. Indirect costs included costs of productivity loss due to premature mortality, and costs of reduced productivity due to absenteeism and presenteeism (reduced on-the-job productivity). The total economic cost of alcohol consumption in Thailand in 2006 was estimated at 156,105.4 million baht (9,627 million US$ PPP) or about 1.99% of the total Gross Domestic Product (GDP). Indirect costs outweigh direct costs, representing 96% of the total cost. The largest cost attributable to alcohol consumption is that of productivity loss due to premature mortality (104,128 million baht/6,422 million US$ PPP), followed by cost of productivity loss due to reduced productivity (45,464.6 million baht/2,804 million US$ PPP), health care cost (5,491.2 million baht/339 million US$ PPP), cost of property damage as a result of road traffic accidents (779.4 million baht/48 million US$ PPP), and cost of law enforcement (242.4 million baht/15 million US$ PPP), respectively. The results from the sensitivity analysis revealed that the cost ranges from 115,160.4 million baht to 214,053.0 million baht (7,102.1 - 13,201 million US$ PPP

Violence against women is now widely recognized as a serious human right abuse, and an important public health problem with substantial consequences physical, mental, sexual, and reproductive health. Data on systematic review of domestic violence are needed to support policy and program recommendations. Therefore, the overall purpose of this systematic review was to assess magnitude of domestic violence against women and associated factors in Ethiopia. Studies systematically reviewed in Federal Democratic Republic of Ethiopia from 2000 to 2014. Systematic review was employed on published research works from databases such as Pubmed, popline, Hinari, and Google using key words. We also consulted public health experts. Community based studies with a study population (15-49 years) were included for review. Thirteen peer reviewed papers and two consecutive Ethiopian demographic and health surveys (2005 and 2011) were included to the systematic review. Twenty seven available in open access journals were retrieved and assessed based on the criteria's such as community based study, cross sectional study design, clearly report prevalence and associated factors were included in the systematic review work. Finally, 15 papers were included in this review. Lifetime prevalence of domestic violence against women by husband or intimate partner among 10 studies ranged from 20 to 78 %. The lifetime domestic physical violence by husband or intimate partner against women ranged from 31 to 76.5 %. The life time domestic sexual violence against women by husband or intimate partner ranged from 19.2 to 59 %. The mean life time prevalence of domestic emotional violence was 51.7 %. Significant number of women experienced violence during their pregnancy period. Domestic violence against women significantly associated with alcohol consumption, chat chewing, family history of violence, occupation, religion, educational status, residence and decision making power.

Studies have indicated that moderate alcohol consumption is associated with lower incidence of diabetes in women. However, not only the amount but also the drinking pattern could be of importance when assessing the longitudinal relation between alcohol and glucose. Also, there is a lack of studies on alcohol use beginning in adolescence on adult glucose levels. The aim was to examine the association between total alcohol consumption and binge drinking between ages 16 and 43 and fasting plasma glucose at age 43. Data were retrieved from a 27-year prospective cohort study, the Northern Swedish Cohort. In 1981, all 9th grade students (n = 1083) within a municipality in Sweden were invited to participate. There were re-assessments at ages 18, 21, 30 and 43. This particular study sample consisted of 897 participants (82.8%). Fasting plasma glucose (mmol/L) was measured at a health examination at age 43. Total alcohol consumption (in grams) and binge drinking were calculated from alcohol consumption data obtained from questionnaires. Descriptive analyses showed that men had higher levels of fasting plasma glucose as compared to women. Men also reported higher levels of alcohol consumption and binge drinking behavior. Linear regressions showed that total alcohol consumption in combination with binge drinking between ages 16 and 43 was associated with elevated fasting plasma glucose at age 43 in women (beta = 0.14, p = 0.003) but not in men after adjustment for BMI, hypertension and smoking at age 43. Our findings indicate that reducing binge drinking and alcohol consumption among young and middle-aged women with the highest consumption might be metabolically favorable for their future glucose metabolism.

International Nuclear Information System (INIS)

Momoh, S.; Soaga, J.

1999-01-01

The study examined the present and future consumption of biomass energy in Nigeria. Direct consumption of fire wood for domestic purposes is the predominant form of biomass energy consumption. Charcoal plays minot roles in biomass energy supply. The current and expected demand for fuelwood is projected to increase by 399% whereas supply is expected to decrease by 17.2% between 1995 and year 2010. Resource adequacy in terms of planned supply is on the decline. Forest estates which is the only planned strategy for fuelwood and wood production is projected to decline from 6.37 million ha. in 1990 to 2.4 million ha, in year 2010. The possibilities of meeting the fuelwood demand in the future is precarious. Policy measures aimed at increasing forest estates. reduction of loss of forest lands to other uses and encouragement of private forestry are recommended

Yong Wang

2018-05-01

Full Text Available Household carbon emissions are important components of total carbon emissions. The consumer side of energy-saving emissions reduction is an essential factor in reducing carbon emissions. In this paper, the carbon emissions coefficient method and Consumer Lifestyle Approach (CLA were used to calculate the total carbon emissions of households in 30 provinces of China from 2006 to 2015, and based on the extended Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT model, the factors influencing the total carbon emissions of households were analyzed. The results indicated that, first, over the past ten years, the energy and products carbon emissions from China’s households have demonstrated a rapid growth trend and that regional distributions present obvious differences. Second, China’s energy carbon emissions due to household consumption primarily derived from the residents’ consumption of electricity and coal; China’s products household carbon emissions primarily derived from residents’ consumption of the high carbon emission categories: residences, food, transportation and communications. Third, in terms of influencing factors, the number of households in China plays a significant role in the total carbon emissions of China’s households. The ratio of children 0–14 years old and gender ratio (female = 100 are two factors that reflect the demographic structure, have significant effects on the total carbon emissions of China’s households, and are all positive. Gross Domestic Product (GDP per capita plays a role in boosting the total carbon emissions of China’s households. The effect of the carbon emission intensity on total household carbon emissions is positive. The industrial structure (the proportion of secondary industries’ added value to the regional GDP has curbed the growth of total carbon emissions from China’s household consumption. The results of this study provide data to support the

Wood, Britta A; Carver, Scott; Troyer, Ryan M; Elder, John H; VandeWoude, Sue

2013-10-31

Microsphere immunoassays (MIAs) allow rapid and accurate evaluation of multiple analytes simultaneously within a biological sample. Here we describe the development and validation of domestic cat-specific MIAs for a) the quantification of total IgG and IgA levels in plasma, and b) the detection of IgG and IgA antibodies to feline immunodeficiency virus (FIV) capsid (CA) and surface (SU) proteins, and feline CD134 in plasma. These assays were used to examine the temporal antibody response of domestic cats infected with apathogenic and pathogenic FIVs, and domestic cats infected with parental and chimeric FIVs of varying pathogenicity. The results from these studies demonstrated that a) total IgG antibodies increase over time after infection; b) α-CA and α-SU IgG antibodies are detectable between 9 and 28 days post-infection and increase over time, and these antibodies combined represent a fraction (1.8 to 21.8%) of the total IgG increase due to infection; c) measurable α-CD134 IgG antibody levels vary among individuals and over time, and are not strongly correlated with viral load; d) circulating IgA antibodies, in general, do not increase during the early stage of infection; and e) total IgG, and α-CA and α-SU IgG antibody kinetics and levels vary with FIV viral strain/pathogenicity. The MIAs described here could be used to screen domestic cats for FIV infection, and to evaluate the FIV-specific or total antibody response elicited by various FIV strains/other diseases. © 2013.

The "prehistory" of marihuana consumption and growing in Colombia between 1930 and 1960

Directory of Open Access Journals (Sweden)

Eduardo Sáenz Rovner

2008-01-01

Full Text Available Marihuana consumption did not become widespread in Colombia as the simple result of its increased use as part of the north-American counterculture of the 1960s. Even though marihuana-growing spiraled to satisfy north-American demand at the end of the 1960s and 1970s there was an important market for domestic consumption in Colombia. "Exonerating-type" academic literature tending to see countries such as Colombia as the passive "victims" of externally-induced phenomena is thus questioned.

Carbon dioxide emissions, output, and energy consumption categories in Algeria.

Amri, Fethi

2017-06-01

This study examines the relation between CO 2 emissions, income, non-renewable, and renewable energy consumption in Algeria during the period extending from 1980 to 2011. Our work gives particular attention to the validity of environmental Kuznets curve (EKC) hypothesis. The autoregressive distributed lag (ARDL) with break point method outcome demonstrates the positive effect of non-renewable type of energy on CO 2 emissions consumption. On the contrary, the results reveal an insignificant effect of renewable energy on environment improvement. Moreover, the results accept the existence of EKC hypothesis but the highest gross domestic product value in logarithm scale of our data is inferior to the estimated turning point. Consequently, policy-makers in Algeria should expand the ratio of renewable energy and should decrease the quota of non-renewable energy consumption.

2014-12-01

The highly-industrialized regions in China have been facing a serious problem of haze mainly consisted of total suspended particulate matter (TSPM), which has attracted great attention from the public since it directly impairs human health and clinically increases the risks of various respiratory and pulmonary diseases. In this paper, we set up a multi-regional input-output (MRIO) model to analyze the transferring routes of TSPM emissions between regions through trades. TSPM emission from particulate source regions and sectors are identified by analyzing the embodied TSPM flows through monetary flow and carbon footprint. The track of TSPM from origin to end via consumption activities are also revealed by tracing the product supply chain associated with the TSPM emissions. Beijing-Tianjin-Hebei (Jing-Jin-Ji) as the most industrialized area of China is selected for a case study. The result shows that over 70% of TSPM emissions associated with goods consumed in Beijing and Tianjin occurred outside of their own administrative boundaries, implying that Beijing and Tianjin are net embodied TSPM importers. Meanwhile, 63% of the total TSPM emissions in Hebei Province are resulted from the outside demand, indicating Hebei is a net exporter. In addition, nearly half of TSPM emissions are the by-products related to electricity and heating supply and non-metal mineral products in Jing-Jin-Ji Area. Based on the model results, we provided new insights into establishing systemic strategies and identifying mitigation priorities to stem TSPM emissions in China.

Full Text Available The Ministry of Rural Development in Hungary has set the goal of restoring the competitiveness of the domestic food industry among many others. They would like to contribute to the stable financing by facilitating borrowing loans as well as export financing the enterprises in the food industry. For the period between 2014 and 2020, 500 billion HUF subsidies have been allocated for the technical and technological modernization of businesses, for the increase of input efficiency as well as for research and development and trainings and consultancy. In order to do so it is essential to encourage the demand for Hungarian food products besides insuring workforce with up-to-date expertise and the supportive economic environment. The research mentions consumption figures based on food balances where the balances calculated for various food groups include food products and beverages converted into ingredients. The development of food consumption is negatively affected by the economic recession, the weather influencing cultivation significantly as well as the fall in consumption from private farming. Enterprises put great emphasis on prevention and on the good physical and mental condition of their colleagues with such organization of work that focuses on health since work can be more efficient by this means. The quality of the work environment influences the health condition both directly and indirectly. In case of micro- and small enterprises cafeteria plans as well as the visible elements of corporate culture are much more revealed thus contributing to more health-conscious food consumption in Zala County. In addition to the agricultural support of the sale of domestic food products, the government could stimulate the manufacturing of healthy products of local small-scale producers indirectly by reducing VAT for instance.

To investigate intergenerational equity in consumption using the Australian National Transfer Accounts (NTA). Australian NTA estimates of consumption were used to investigate disparities in consumption between people of different ages and generations in Australia between 1981-1982 and 2009-2010. There is a clear patterning of consumption by age, with the distribution by age of consumption funded by the private sector being very different to that of consumption funded by the public sector. Australians have achieved notable equality in total consumption among people between the ages of 20 and 75 years. Substantial disparities exist, however, between different generations, with earlier generations experiencing lower levels of total consumption in real terms at particular ages than later generations. An accurate picture of intergenerational equity in consumption requires consideration of both cohorts and cross sections, as well as consumption funded by both the public and the private sectors. © 2017 AJA Inc.

2018-01-01

Full Text Available This paper describes the preliminary monitoring results of an onsite pilot wastewater treatment plant consisting of a septic tank, an anaerobic up-flow filter, and a horizontal subsurface flow wetland system planted with Agapanthus africanus. The system was designed to treat heavily polluted domestic wastewater produced in a research and development (R&D center, reaching additional goals of zero energy consumption and eliminating the use of chemical additives. First water quality data shows that organic load in the treated sewage were removed achieving more than 95% efficiency. Nutrients were removed by almost 50%, and fecal and total coliform counts decreased by 99.96%. The results were compared to official Mexican regulations for wastewater discharged into lakes and reservoirs complied with all of them except for nutrients. In this pilot project, the resulting treated wastewater was directly reused for watering the green areas of the R&D center. The result was that the excess of nutrients improved the quality of the grass, avoiding the use of synthetic fertilizers, and created a wetland habitat for small wildlife species living in the area.

Comparison of the Fecal Microbiota in Feral and Domestic Goats

María G. Domínguez-Bello

2011-12-01

Full Text Available Animals have co-evolved with mutualistic microbial communities, known as the microbiota, which are essential for organ development and function. We hypothesize that modern animal husbandry practices exert an impact on the intestinal microbiota. In this study, we compared the structure of the fecal microbiota between feral and domestic goats using the G2 PhyloChip and assessed the presence of five tetracycline resistance genes [tet(M, tet(S, tet(O, tet(Q and tet(W] by PCR. Feces were collected from 10 goats: 5 domestic from a farm in the main island of Puerto Rico and 5 feral from the remote dry island of Mona. There were 42 bacterial phyla from 153 families detected in the goats’ feces. A total of 84 PhyloChip-OTUs were different in the fecal microbiota of feral and domestic goat. Both feral and domestic goats carried antibiotic resistance genes tet(O and tet(W, but domestic goats additionally carried tet(Q. Diet, host genetics and antibiotic exposure are likely determinant factors in shaping the intestinal microbiota and may explain the differences observed between feral and domestic goats fecal microbiota.

2018-03-01

The main objective of this study was to assess the risk factors and spatial correlates of domestic violence against women of reproductive age in Rwanda. A structured spatial approach was used to account for the nonlinear nature of some covariates and the spatial variability on domestic violence. The nonlinear effect was modeled through second-order random walk, and the structured spatial effect was modeled through Gaussian Markov Random Fields specified as an intrinsic conditional autoregressive model. The data from the Rwanda Demographic and Health Survey 2014/2015 were used as an application. The findings of this study revealed that the risk factors of domestic violence against women are the wealth quintile of the household, the size of the household, the husband or partner's age, the husband or partner's level of education, ownership of the house, polygamy, the alcohol consumption status of the husband or partner, the woman's perception of wife-beating attitude, and the use of contraceptive methods. The study also highlighted the significant spatial variation of domestic violence against women at district level.

2016-09-01

A key future challenge of domestic wastewater treatment is nutrient recovery while still achieving acceptable discharge limits. Nutrient partitioning using purple phototrophic bacteria (PPB) has the potential to biologically concentrate nutrients through growth. This study evaluates the use of PPB in a continuous photo-anaerobic membrane bioreactor (PAnMBR) for simultaneous organics and nutrient removal from domestic wastewater. This process could continuously treat domestic wastewater to discharge limits (60% of PPB, though the PPB community was highly variable. The outcomes from the current work demonstrate the potential of PPB for continuous domestic (and possibly industrial) wastewater treatment and nutrient recovery. Technical challenges include the in situ COD supply in a continuous reactor system, as well as efficient light delivery. Addition of external (agricultural or fossil) derived organics is not financially nor environmentally justified, and carbon needs to be sourced internally from the biomass itself to enable this technology. Reduced energy consumption for lighting is technically feasible, and needs to be addressed as a key objective in scaleup. Copyright © 2016 Elsevier Ltd. All rights reserved.

Divisia amount and price index for energy consumption

International Nuclear Information System (INIS)

Bentzen, J.

1993-01-01

In connection with the calculation of total energy consumption related to aggregation of the individual fuel's combustion values, an alternative to Btu aggregation (combustion value measurement), designated the ''Divisia index'', is presented. This represents an economic measure for energy consumption. The Divisia index is demonstrated in relation to total national energy consumption and total energy consumption within the Danish housing sector and also with regard to the estimation of price and income elasticity within energy demand. It is only possible to utilize the Divisia index in relation to the last 20 years, which is the period where energy consumption has stagnated. The question of possible irreversible effects on energy consumption caused by large variations in energy prices is discussed. It is suggested that the reaction to a fall in prices is different and less significant than is the case with price rises. In the long term, results point at a reasonably high price elasticity within energy demand. (AB) (22 refs.)

The UK-DALE dataset, domestic appliance-level electricity demand and whole-house demand from five UK homes

Science.gov (United States)

Kelly, Jack; Knottenbelt, William

2015-03-01

Many countries are rolling out smart electricity meters. These measure a home’s total power demand. However, research into consumer behaviour suggests that consumers are best able to improve their energy efficiency when provided with itemised, appliance-by-appliance consumption information. Energy disaggregation is a computational technique for estimating appliance-by-appliance energy consumption from a whole-house meter signal. To conduct research on disaggregation algorithms, researchers require data describing not just the aggregate demand per building but also the ‘ground truth’ demand of individual appliances. In this context, we present UK-DALE: an open-access dataset from the UK recording Domestic Appliance-Level Electricity at a sample rate of 16 kHz for the whole-house and at 1/6 Hz for individual appliances. This is the first open access UK dataset at this temporal resolution. We recorded from five houses, one of which was recorded for 655 days, the longest duration we are aware of for any energy dataset at this sample rate. We also describe the low-cost, open-source, wireless system we built for collecting our dataset.

2016-12-09

Combustible and smokeless tobacco use causes adverse health outcomes, including cardiovascular disease and multiple types of cancer (1,2). Standard approaches for measuring tobacco use include self-reported surveys of use and consumption estimates based on tobacco excise tax data (3,4). To provide the most recently available tobacco consumption estimates in the United States, CDC used federal excise tax data to estimate total and per capita consumption during 2000-2015 for combustible tobacco (cigarettes, roll-your-own tobacco, pipe tobacco, small cigars, and large cigars) and smokeless tobacco (chewing tobacco and dry snuff). During this period, total combustible tobacco consumption decreased 33.5%, or 43.7% per capita. Although total cigarette consumption decreased 38.7%, cigarettes remained the most commonly used combustible tobacco product. Total noncigarette combustible tobacco (i.e., cigars, roll-your-own, and pipe tobacco) consumption increased 117.1%, or 83.8% per capita during 2000-2015. Total consumption of smokeless tobacco increased 23.1%, or 4.2% per capita. Notably, total cigarette consumption was 267.0 billion cigarettes in 2015 compared with 262.7 billion in 2014. These findings indicate that although cigarette smoking declined overall during 2000-2015, and each year from 2000 to 2014, the number of cigarettes consumed in 2015 was higher than in 2014, and the first time annual cigarette consumption was higher than the previous year since 1973. Moreover, the consumption of other combustible and smokeless tobacco products remains substantial. Implementation of proven tobacco prevention interventions (5) is warranted to further reduce tobacco use in the United States.

2013-01-01

The domestic heating sector has a high potential in terms of energy savings and environmental impact. In the present study, an analysis has been carried out on the effect of domestic heating on natural gas (NG) consumption and pollutants emissions. In particular, among various emission pollutants, the nitrogen oxides (NO x ) emissions at national level were analyzed in detail. The work was carried out under a collaborative research project between the Italian Ministry of the Environment and Politecnico di Milano. For the assessment of the national NO x emissions due to residential heating, an inventory of the domestic boilers stock operating in Italy from 1999 to 2010 was made. As from a technological point of view, the precise data about the real composition of national domestic boilers stock were incomplete and not updated, a methodological procedure was developed in order to reconstruct the national domestic boilers stock based on the available technologies and thermal power. According to this scenario, the technological improvement of national boilers stock in the last decade was evaluated in terms of natural gas saving and reduced NO x emissions. Further some discussion has been made on the energy policies for the diffusion of more efficient boilers. - Highlights: ► First-of-its-kind study on the effect of domestic heating on NO x emissions. ► Inventory of national gas boiler population for domestic heating. ► Estimation of the main boilers typologies distribution on a national level. ► Technological improvement of thermal appliances and NO x emissions reduction.

1997-01-01

A questionnaire survey, to estimate biofuel consumption rates in rural and urban households in Zimbabwe, was conducted during the months of March and April 1995. The survey formed part of an integrated campaign aimed at establishing the extent to which domestic biofuel burning in Africa contributes to the atmospheric trace gas budget. Five study areas, four rural and one urban, were covered by the survey. The forms of biofuel used in rural areas were found to be wood, agricultural residues and cow dung, with wood being predominant. When available, agricultural residues were the second most popular form of fuel. Cow dung was only used in situations of severe fuel shortages. On average, rural consumption rates of wood, agricultural residues and cow dung for this time of the year were found to be 3.2, 1.5 and 0.2 kg/capita/day respectively. Wood and agricultural residues were the only biofuels used by urban households and were consumed at rates of 1.6 and > 0.1 kg/capitaday respectively. Across the study areas, consumption rates were a function of fuel availability. (author)

Suolanen, V.

1994-02-01

In the study the contamination of domestic animal products (milk, beef, pork) and grain is predicted applying a compartment model approach to simulate the dynamic behaviour of radionuclides in the biosphere after an accidental atmospheric deposition. Further, the radionuclide intakes into human body by consumption of the contaminated domestic animal products and the arising internal doses, are studied. The contamination of domestic animal products and grain are predicted by considering three representative deposition cases. The considered deposition timepoints are: spring (1st of May), summer (1st of July) and autumn (1st of September). The nuclides considered are 137 Cs, 134 Cs and 90 Sr. (18 refs., 14 figs., 8 tabs.)

Full Text Available Fish consumption preferences are affected by individuals’ socioeconomic characteristics. The aims of the present paper were (i to obtain information on fish consumption level and frequency; (ii to investigate the associations between the socioeconomic characteristics of consumers and their preferences; and (iii to examine the influence of determinants on fish consumption. Data were gathered through a questionnaire completed by a total of 127 randomly selected individuals from different socioeconomic backgrounds from the Antakya, Turkey. The average consumption was found to be 2.98 kg/person/year for fish. Anchovies, gilt-head sea bream, and sea bass were reported as the most consumed three species, respectively. Significant differences in fish consumption were found among age groups, gender groups, and education groups, as well as between marital statuses. A majority of the consumers eat fish once a month throughout the year or only during the winter months. Fish consumption level and frequency were significantly positively correlated with education (p<0.01, income (p<0.05 and total meat consumption (p<0.01. The stepwise multiple regression model explained 41.7% (p<0.01 of the total variance for fish consumption. The amount and frequency of the consumption in the region, which is very far below the world and Turkey average especially for lower socioeconomic groups and for less-consumed fish species, can be increased by certain policies, such as training, advertising and different marketing strategies. Moreover, consumption should be distributed equally throughout the year instead of consuming only in certain seasons.

Despite their ability to interbreed and produce fertile offspring, there is continued disagreement about the genetic relationship of the domestic horse (Equus caballus) to its endangered wild relative, Przewalski's horse (Equus przewalskii). Analyses have differed as to whether or not Przewalski's horse is placed phylogenetically as a separate sister group to domestic horses. Because Przewalski's horse and domestic horse are so closely related, genetic data can also be used to infer domestication-specific differences between the two. To investigate the genetic relationship of Przewalski's horse to the domestic horse and to address whether evolution of the domestic horse is driven by males or females, five homologous introns (a total of approximately 3 kb) were sequenced on the X and Y chromosomes in two Przewalski's horses and three breeds of domestic horses: Arabian horse, Mongolian domestic horse, and Dartmoor pony. Five autosomal introns (a total of approximately 6 kb) were sequenced for these horses as well. The sequences of sex chromosomal and autosomal introns were used to determine nucleotide diversity and the forces driving evolution in these species. As a result, X chromosomal and autosomal data do not place Przewalski's horses in a separate clade within phylogenetic trees for horses, suggesting a close relationship between domestic and Przewalski's horses. It was also found that there was a lack of nucleotide diversity on the Y chromosome and higher nucleotide diversity than expected on the X chromosome in domestic horses as compared with the Y chromosome and autosomes. This supports the hypothesis that very few male horses along with numerous female horses founded the various domestic horse breeds. Patterns of nucleotide diversity among different types of chromosomes were distinct for Przewalski's in contrast to domestic horses, supporting unique evolutionary histories of the two species.

Highlights: ► Rural household energy mainly derives from available biomass resources. ► Household energy consumption structure experiencing substantial transformation. ► Biogas energy plays an important roles in rural household energy consumption. ► Biogas digester construction has a profound implication for applied energy. -- Abstract: A comprehensive investigation was conducted to evaluate the efficiency of newly installed biogas digesters in saving biomass resources and addressing energy squandering. Compared with traditional coal-based or firewood dominated energy consumption, the biogas digesters economize on energy resources due to higher heat efficiency. Furthermore, since crop residues of straw and other domestic animal and human excreta are effectively recycled and reused as anaerobic fermentation materials of biogas digesters, greenhouse gas emissions are significantly reduced by converting the previous extensive combustion of such into a sustainable and highly efficient practice in the rural region. The results in this study show that total energy consumption is 412 kgce (kgce: 1 kg standard coal. 1 kgce = 29.31 MJ) in Xiyang Township in 2009. The construction of biogas digesters significantly contributes to the transformation of rural household energy consumption structure, though biogas as a renewable energy only accounts for 6.31% of the total household energy consumption. Per capita rural household energy consumption is 393.07 kgce in household with biogas digesters and 437.60 kgce in household without biogas digesters. In addition, application of biogas dregs, slurry, and marsh liquid to the agricultural crops have greatly reduced the expenditure of buying chemical fertilizers. The average commercial fertilizer per mu (0.067 ha) in rural households using biogas digesters is 12.43 kg and the cost per mu is 29.53 yuan (1 yuan = 0.1523 dollar), while rural households without biogas digesters use 25.22 kg of commercial fertilizers and cost 59

DOES ENERGY CONSUMPTION VOLATILITY AFFECT REAL GDP VOLATILITY? AN EMPIRICAL ANALYSIS FOR THE UK

Directory of Open Access Journals (Sweden)

2013-10-01

Full Text Available This paper empirically examines the relation between energy consumption volatility and unpredictable variations in real gross domestic product (GDP in the UK. Estimating the Markov switching ARCH model we find a significant regime switching in the behavior of both energy consumption and GDP volatility. The results from the Markov regime-switching model show that the variability of energy consumption has a significant role to play in determining the behavior of GDP volatilities. Moreover, the results suggest that the impacts of unpredictable variations in energy consumption on GDP volatility are asymmetric, depending on the intensity of volatility. In particular, we find that while there is no significant contemporaneous relationship between energy consumption volatility and GDP volatility in the first (low-volatility regime, GDP volatility is significantly positively related to the volatility of energy utilization in the second (high-volatility regime.

Accounting for Water Insecurity in Modeling Domestic Water Demand

Water demand management uses price elasticity estimates to predict consumer demand in relation to water pricing changes, but studies have shown that many additional factors effect water consumption. Development scholars document the need for water security, however, much of the water security literature focuses on broad policies which can influence water demand. Previous domestic water demand studies have not considered how water security can affect a population's consumption behavior. This study is the first to model the influence of water insecurity on water demand. A subjective indicator scale measuring water insecurity among consumers in the Palestinian West Bank is developed and included as a variable to explore how perceptions of control, or lack thereof, impact consumption behavior and resulting estimates of price elasticity. A multivariate regression model demonstrates the significance of a water insecurity variable for data sets encompassing disparate water access. When accounting for insecurity, the R-squaed value improves and the marginal price a household is willing to pay becomes a significant predictor for the household quantity consumption. The model denotes that, with all other variables held equal, a household will buy more water when the users are more water insecure. Though the reasons behind this trend require further study, the findings suggest broad policy implications by demonstrating that water distribution practices in scarcity conditions can promote consumer welfare and efficient water use.

Today's virtual water consumption and trade under future water scarcity

International Nuclear Information System (INIS)

Orlowsky, B; Gudmundsson, L; Seneviratne, Sonia I; Hoekstra, A Y

2014-01-01

The populations of most nations consume products of both domestic and foreign origin, importing together with the products the water which is expended abroad for their production (termed ‘virtual water’). Therefore, any investigation of the sustainability of present-day water consumption under future climate change needs to consider the effects of potentially reduced water availability both on domestic water resources and on the trades of virtual water. Here we use combinations of Global Climate and Global Impact Models from the ISI–MIP ensemble to derive patterns of future water availability under the RCP2.6 and RCP8.5 greenhouse gas (GHG) concentrations scenarios. We assess the effects of reduced water availability in these scenarios on national water consumptions and virtual water trades through a simple accounting scheme based on the water footprint concept. We thereby identify countries where the water footprint within the country area is reduced due to a reduced within-area water availability, most prominently in the Mediterranean and some African countries. National water consumption in countries such as Russia, which are non-water scarce by themselves, can be affected through reduced imports from water scarce countries. We find overall stronger effects of the higher GHG concentrations scenario, although the model range of climate projections for single GHG concentrations scenarios is in itself larger than the differences induced by the GHG concentrations scenarios. Our results highlight that, for both investigated GHG concentration scenarios, the current water consumption and virtual water trades cannot be sustained into the future due to the projected patterns of reduced water availability.

Energy consumption: energy consumption in mainland Norway

Energy Technology Data Exchange (ETDEWEB)

Magnussen, Inger Helene; Killingland, Magnus; Spilde, Dag

2012-07-25

The purpose of this report is to describe trends in energy consumption in mainland Norway, with an emphasis on key trends within the largest consumer groups. We also explain common terms and concepts in the field of energy consumption. Finally, we look at forecasts for future energy consumption, produced by bodies outside NVE. Total final energy consumption in mainland Norway in 2009 was 207 TWh. The most important end-user groups are households, service industries, manufacturing industry and transport. In addition, the energy sector in mainland Norway consumed 15 TWh. Energy consumed in the energy sector is not considered as final consumption, as the energy is used to produce new energy products. The long-term trend in energy consumption in mainland Norway is that fuel in the transport sector and electricity for the energy sector increases, while energy consumption in other sectors flattens out. The main reason for an increased use of fuel in the transport sector is the rise in the number of motorised machinery and vehicles in mainland Norway. This has caused a rise in gasoline and diesel consumption of 75 per cent since 1976. The petroleum sector is the largest consumer of energy within the energy sector in mainland Norway, and electricity from onshore to platforms in the North Sea and to new shore side installations has led to a rise in electricity consumption from 1 TWh in 1995 to 5 TWh in 2009. The energy consumption in households showed flat trend from 1996 to 2009, after many years of growth. The main reasons are a warmer climate, higher energy prices, the use of heats pumps and more energy-efficient buildings. In the service industries, the growth in energy consumptions has slightly decreased since the late 1990s, for much the same reasons as for households. In manufacturing industries the energy consumption have flatten out mainly due to the closure of energy-intensive businesses and the establishment of new more energy-efficient businesses. Electricity is

An island-wide collection of tick species infesting humans, domesticated and wild animals and questing ticks in domestic and peridomestic environments was carried out during 2009-2011. A total of 30,461 ticks were collected from 30 different hosts and free living stages from the ground. The collection consisted of 22 tick species from 30 different hosts recording 12 tick species from humans, 19 from domesticated animals and 21 from wild animals, with a total of 97 new host records. The most common tick species on humans were Dermacentor auratus and Amblyomma testudinairum, while Haemaphysalis intermedia, Rhipicephalus microplus and Rhipicephalus sanguineus were common in domesticated and wild animals sharing 20 host species. Among the questing ticks, immature D. auratus was the most abundant. Humans and domesticated animals were mostly infested by the nymphal stages while adult ticks were found on wild animals. High number of new host records could be due to domestic animals picking tick species from wildlife and vise versa at the human/animal interface. Habitat destruction due to forest fragmentation has lead to wild animals roaming in urban and semi-urban neighbourhoods increasing the interactions of wild animals with domesticated animals. Wild animals play a significant role as a reservoir of many tick borne infections which can easily be spread to domesticated animals and then to humans via tick infestations. Data in this paper are useful for those interested in tick infesting wild and domestic animals and humans in describing the zoonotic potential of tick borne infections. Copyright © 2014 Elsevier B.V.

Global dietary and lifestyle trends are primary risk factors for communicable and non-communicable diseases. An ecological analysis was conducted to examine the association of global dietary and lifestyle patterns with total cholesterol concentrations. This study also investigated whether total cholesterol modified the association between dietary and lifestyle habits with disability-adjusted-life-years-lost (DALYs) for infectious and cardiovascular diseases (CVDs). Country-specific mean total cholesterol concentrations and DALYs for infectious and CVDs were obtained. Data were then matched to country-specific food and energy availability for consumption and information on obesity, physical inactivity, urbanization, gross domestic product (GDP), life expectancy and smoking. Stepwise multiple regression models were developed to identify significant predictors of total cholesterol concentrations and DALYs for infectious and CVDs. Life expectancy and egg and meat consumption were significantly associated with cholesterol concentrations. DALYs for infectious diseases were associated with smoking, life expectancy and per capita GDP. Smoking was the only predictor of DALYs for CVDs. The improvement of socio-demographic conditions and economic growth is likely to reduce the burden of communicable diseases in developing countries. A concurring increase in non-communicable diseases is expected, and these results have, yet again, identified smoking as a primary risk factor for CVDs.

Hussain, Anwar; Rahman, Muhammad; Memon, Junaid Alam

2016-01-01

Growing shortfall of electricity in Pakistan affects almost all sectors of its economy. For proper policy formulation, it is imperative to have reliable forecasts of electricity consumption. This paper applies Holt-Winter and Autoregressive Integrated Moving Average (ARIMA) models on time series secondary data from 1980 to 2011 to forecast total and component wise electricity consumption in Pakistan. Results reveal that Holt-Winter is the appropriate model for forecasting electricity consumption in Pakistan. It also suggests that electricity consumption would continue to increase throughout the projected period and widen the consumption-production gap in case of failure to respond the issue appropriately. It further reveals that demand would be highest in the household sector as compared to all other sectors and the increase in the energy generation would be less than the increase in total electricity consumption throughout the projected period. The study discuss various options to reduce the demand-supply gap and provide reliable electricity to different sectors of the economy. - Highlights: • We forecast total and component wise electricity consumption for Pakistan. • Electricity shortfall in Pakistan will increase in future if same situation exists. • Various options exist to cope with the electricity crisis in the country. • Holt-winter model gives best forecasts for electricity consumption in the country.

Diesel Consumption of Agriculture in China

Shusen Gui

2012-12-01

Full Text Available As agricultural mechanization accelerates the development of agriculture in China, to control the growth of the resulting energy consumption of mechanized agriculture without negatively affecting economic development has become a major challenge. A systematic analysis of the factors (total power, unit diesel consumption, etc. influencing diesel consumption using the SECA model, combined with simulations on agricultural diesel flows in China between 1996 and 2010 is performed in this work. Seven agricultural subsectors, fifteen categories of agricultural machinery and five farm operations are considered. The results show that farming and transportation are the two largest diesel consumers, accounting for 86.23% of the total diesel consumption in agriculture in 2010. Technological progress has led to a decrease in the unit diesel consumption and an increase in the unit productivity of all machinery, and there is still much potential for future progress. Additionally, the annual average working hours have decreased rapidly for most agricultural machinery, thereby influencing the development of mechanized agriculture.

Full Text Available The world experienced in dramatic price surge of food commodities since mid of 2007 to 2008. It was claimed that the crisis were being mainly for backdrop of global shocks in food and energy price. But how the shocks come to domestic market from external sources is a researchable phenomenon. Surprisingly few attempts have been made to systematically analysis of shock transmission from international to domestic market. The study analyzed the effect of global commodity market factors and domestic exchange rate development on domestic food price in Bangladesh. A bi-variants co-integration approach was applied for the analysis of shock transmission. Finally an error correction model was developed. The overall magnitudes of the pass through suggest that only 46 per cent of the total world shock pass-through in domestic economy.

Full Text Available Abstract Background Domestic animals and their wild relatives differ in a wide variety of aspects. The process of domestication of the domestic guinea pig (Cavia aperea f. porcellus, starting at least 4500 years ago, led to changes in the anatomy, physiology, and behaviour compared with their wild relative, the wild cavy, Cavia aperea. Although domestic guinea pigs are widely used as a laboratory animal, learning and memory capabilities are often disregarded as being very scarce. Even less is known about learning and memory of wild cavies. In this regard, one striking domestic trait is a reduction in relative brain size, which in the domesticated form of the guinea pig amounts to 13%. However, the common belief, that such a reduction of brain size in the course of domestication of different species is accomplished by less learning capabilities is not at all very well established in the literature. Indeed, domestic animals might also even outperform their wild conspecifics taking advantage of their adaptation to a man-made environment. In our study we compared the spatial learning abilities of wild and domestic guinea pigs. We expected that the two forms are different regarding their learning performance possibly related to the process of domestication. Therefore wild cavies as well as domestic guinea pigs of both sexes, aged 35 to 45 days, were tested in the Morris water maze to investigate their ability of spatial learning.

Full Text Available Energy consumption during waste water treatment is a very important factor affecting food industry plants. Apart from highly efficient treatment of dairy and meat sewage, a low energy consumption is required in order to lower its costs. During the research period parameters of raw and treated sewage were tested (BOD, COD, N-total, P-total. Also, the energy consumption from selected processes as well as total consumption were measured. Indicators of energy consumption per m3 and removed load were calculated. It was found that biological treatment and aeration played the main role in energy consumption in both objects. It was respectively 40 and 47% for Bielmlek and JBB plants. The second biggest energy consuming stage of treatment in both objects was sludge processing. Energy required to process excessive sludge equaled 30% of the total energy usage in both plants. Energy consumption factors related to hydraulic flow gave results in the range from 2,05 to 3,3 kWhm-3 and from 2,72 to 3,23 kWhm-3 for Bielmlek and JBB plants respectively. The research will be continued in order to optimize energy consumption while retaining high efficiency treatment in food industry WWTPs. Finally a mathematical model will be prepared for optimizing energy consumption in food industry WWTPs.

Contribution of domestic industry to the spanish nuclear program

International Nuclear Information System (INIS)

Palacios, L.

1987-01-01

The incorporation of nuclear energy to the spanish electricity supply system dates back to the 1960's, when the industrial infrastructure of the country was being modernized. The first round of Nuclear Power Plants was ordered on a turnkey basis from foreign established vendors and the participation of domestic suppliers of mechanical and electrical equipment was smaller than that of engineering, construction and erection companies. The 1960's and early 1970's witnessed a high rate of growth in electricity consumption. This fact plus the scarcity of domestic energy resources prompted an ambitious energy plan with a strong nuclear component. A second round of non-turnkey orders was placed by the Spanish utilities. Spanish industry, on the basis of a reliable market and the government guidelines to increase substantially the domestic participation, launched a determined effort to reorganize its activities to produce high quality, competitive components. The main thrust of this effort was directed to creating quality asurance systems, assimilating construction codes such as ASME Section III and realizing some investment in equipment and acquisition of manufacturing knowhow. Existing plants were largely used. A third round of plants was ordered during the 1970's for which full participation was targeted. During this phase this industrial infrastructure was completed with some new plants (for primary components and fuel fabrication) and a host of smaller, specialized firms for parts and services. The present situation is one of maturity in the design and manufacturing capacity for most components, with the exception of some raw materials and specialized items for which the economic threshold far exceeds the domestic needs...

Full Text Available Abstract Background There is evidence that the adverse consequences of alcohol impose a substantial economic burden on societies worldwide. Given the lack of generalizability of study results across different settings, many attempts have been made to estimate the economic costs of alcohol for various settings; however, these have mostly been confined to industrialized countries. To our knowledge, there are a very limited number of well-designed studies which estimate the economic costs of alcohol consumption in developing countries, including Thailand. Therefore, this study aims to estimate these economic costs, in Thailand, 2006. Methods This is a prevalence-based, cost-of-illness study. The estimated costs in this study included both direct and indirect costs. Direct costs included health care costs, costs of law enforcement, and costs of property damage due to road-traffic accidents. Indirect costs included costs of productivity loss due to premature mortality, and costs of reduced productivity due to absenteeism and presenteeism (reduced on-the-job productivity. Results The total economic cost of alcohol consumption in Thailand in 2006 was estimated at 156,105.4 million baht (9,627 million US$ PPP or about 1.99% of the total Gross Domestic Product (GDP. Indirect costs outweigh direct costs, representing 96% of the total cost. The largest cost attributable to alcohol consumption is that of productivity loss due to premature mortality (104,128 million baht/6,422 million US$ PPP, followed by cost of productivity loss due to reduced productivity (45,464.6 million baht/2,804 million US$ PPP, health care cost (5,491.2 million baht/339 million US$ PPP, cost of property damage as a result of road traffic accidents (779.4 million baht/48 million US$ PPP, and cost of law enforcement (242.4 million baht/15 million US$ PPP, respectively. The results from the sensitivity analysis revealed that the cost ranges from 115,160.4 million baht to 214

Highlights: • A novel MDACWH was presented and experimentally studied. • MDACWH has high performance on making domestic hot water and air conditioning. • The time for heating water reduced to 22.0 min after modification. • Average COP reached 4.32, which was 1.58 times higher than the unmodified unit. - Abstract: The recovery of condenser heat is concerned one of the most effective methods to curb energy consumption in residential dwellings. Aiming at recovering the condenser heat of domestic air conditioner, this paper experimentally studied a multi-functional domestic air conditioner with integrated water heater (MDACWH) which can effectively provide space – cooling and domestic hot water simultaneously. The dynamic operation characteristics, such as hot water supply and energy efficiency were tested to verify the availability of the MDACWH. The results showed that the MDACWH can effectively heat the domestic hot water without losing its cooling capacity. It was also found that with the use of MDACWH, the coefficient of comprehensive energy performance of the MDACWH was about 1.58 times higher than that of the unmodified experimental unit. Furthermore, the water-heating time was shorten remarkably from 128.5 min to 22.0 min. The novel domestic air conditioner, compared with the unmodified initial prototype, can be more practical and provide significant energy savings in space-cooling and hot water supply.

Increasing dietary sodium drives the thirst response. Because sugar-sweetened beverages (SSBs) are frequently consumed by children, sodium intake may drive greater consumption of SSBs and contribute to obesity risk. We examined the association between dietary sodium, total fluid, and SSB consumption in a nationally representative sample of US children and adolescents aged 2-18 y. We analyzed cross-sectional data from NHANES 2005-2008. Dietary sodium, fluid, and SSB intakes were assessed with a 24-h dietary recall. Multiple regression analysis was used to assess associations between sodium, fluid, and SSBs adjusted for age, sex, race-ethnic group, body mass index (BMI), socioeconomic status (SES), and energy intake. Of 6400 participants, 51.3% (n = 3230) were males, and the average (±SEM) age was 10.1 ± 0.1 y. The average sodium intake was 3056 ± 48 mg/d (equivalent to 7.8 ± 0.1 g salt/d). Dietary sodium intake was positively associated with fluid consumption (r = 0.42, P sodium is positively associated with fluid consumption and predicted SSB consumption in consumers of SSBs. The high dietary sodium intake of US children and adolescents may contribute to a greater consumption of SSBs, identifying a possible link between dietary sodium intake and excess energy intake.

Full Text Available Purpose of the study. The fuel and energy complex is one of the important components of the mechanism of functioning of the national economy in general and municipal economy in particular, since the main tasks of the complex include: provision of hot water supply all year round and heat during the winter period, meeting the needs of the population and municipal economy in gas, supply of gasoline and diesel fuel to satisfy consumers, as well as the supply of coal, peat, fuel oil and other fuels for the urban economy. An important role is played by enterprises of the fuel and energy complex in terms of providing jobs to the population. The fuel and energy complex of Moscow is one of the largest in Russia. A feature of its functioning is the concentrated consumption of gas, fuel, electricity, heat energy and other energy resources. The formation and development of the fuel and energy complex in Moscow is largely due to the rapidly developing economy of the megapolis – large-scale construction of housing and infrastructure, sustainable population growth entails a constant increase in consumption of fuel and energy resources. Monitoring the efficiency of the use of fuel and energy resources makes it possible to identify ways to reduce the volume of consumption to a level that allows, within the approved limit, to implement the planned rate of social and economic development of the city. Materials and methods. Information base of the research was made by statistical data characterizing the volume of consumption of certain types of fuel and energy resources in the market of the Moscow region. The methodological basis of the study is made up of statistical methods of analysis of structure and structural shifts, dynamics.

Not just a fallback food: global patterns of insect consumption related to geography, not agriculture.

Science.gov (United States)

Lesnik, Julie J

2017-07-08

Insects as food are often viewed as fallback resources and associated with marginal environments. This study investigates the relationship between insect consumption and noncultivated landscapes as well as with other independent variables including latitude, area, population, and gross domestic product. Data were obtained from online databases including the World List of Edible Insects, the World Bank, and the World Factbook. A logistic regression model found that latitude could correctly predict the presence of edible insects 80% of the time and that arable land and gross domestic product showed no effect. Spearman rank-order correlation with number of insect species found significant relationships between area and population (but not density) and per capita gross domestic product as well as latitude. Further analysis of latitude using paired Mann-Whitney tests identified a general gradient pattern in reduction of edible insects with increased latitude. Results suggest that insect consumption represents a dynamic human-environment interaction, whereby insects are utilized in some of the world's lushest environments as well as areas where people have had great impact on the ecosystem. The concept that insects are a fallback food is an oversimplification that is likely rooted in Western bias against this food source. © 2017 Wiley Periodicals, Inc.

Annual consumption of 10 classes of food and drink is reported for the total population of each EC-country. National food consumption data are generalized by distinguishing groups of countries with similar diet. Group 1: UK and Ireland (low consumption of fruit, high consumption of potatoes and fresh dairy products). Group 2: Italy and Greece (high consumption of cereals, vegetables and fruit, low consumption of fresh dairy products). Group 3: France, Belgium, Luxembourg, Netherlands, FRG and Spain (intermediate consumption of most foodstuffs). Portugal and Denmark could not be classified in any group. Changes in food consumption related to differences in age, sex, social class, regional habits and level of urbanisation are reported.In some cases, variation of annual food consumption over the different seasons on the relative contribution of food from local origin to the total diet, could be estimated. Differences of region, age and level of urbanisation appear to have the largest influence on consumed amounts. As for age, the values for the different age-groups range from 50 to 80 percent of the adult diet. Regional consumption may diverge from 70-130 percent of the average national consumption, with values of 200 percent for potatoes and fruit. Consumption in urban areas compared with the entire country diverges from 70-100 percent. In rural areas the values diverge from 100-140 percent. Self-support of vegetables and milk seems to be important for most countries. Of the other products, self-support of wheat and cheese is only of importance in the south of the EC. When combining the effects of the different factors, a range of consumed amounts for specific population groups of 50 to 200 percent of the average national consumption was determined.

To determine the prevalence of, and independent risk factors for various domestic violence categories among married women of reproductive age in southwestern Turkey. The present cross-sectional study included 260 randomly selected women registered to a family physician in the district of Gönen, Isparta. During home visits between October 1 and December 31, 2012, the women completed a questionnaire that included between four and eight questions for each violence category (physical, verbal, economic, emotional, and sexual) to assess the lifetime presence of domestic violence. Logistic regression models with backward elimination were constructed to define independent risk factors for domestic violence. In total, 176 (67.7%) women reported any type of domestic violence at least once in their lifetime. Verbal/psychological abuse was the most frequent type (reported by 121 [46.5%] women). Living in a village, young age (19-29 years) of the husband, adolescent age (violence. Attention should be given to area of residence, age of both partners at marriage, adolescent marriage, and husband characteristics during screening for domestic violence.

While the problem of climate change is being perceived as increasingly urgent, decision-makers struggle to agree on the distribution of responsibility across countries. In particular, representatives from countries hosting emissions-intensive exporting industries have argued that the importers of emissions-intensive goods should bear the responsibility, and ensuing penalties. Indeed, international trade and carbon leakage appear to play an increasingly important role in the carbon emissions debate. However, definitions of quantities describing the embodiment of carbon emissions in internationally traded products, and their measurement, have to be sufficiently robust before being able to underpin global policy. In this paper we critically examine a number of emissions accounting concepts, examine whether the ensuing carbon balances are compatible with monetary trade balances, discuss their different interpretations, and highlight implications for policy. In particular, we compare the emissions embodied in bilateral trade (EEBT) method which considers total trade flows with domestic emission intensities, with the multi-regional input-output (MRIO) method which considers trade only into final consumption with global emission intensities. If consumption-based emissions of different countries were to be compared, we would suggest an MRIO approach because of the global emissions coverage inherent in this method. If trade-adjusted emission inventories were to be compared, we would suggest an EEBT approach due to the consistency with a monetary trade balance.

Inadequate hydration is a public health issue that imposes a significant economic burden. In Spain, data of total water intake (TWI) are scarce. There is a clear need for a national study that quantifies water and beverage intakes and explores associations between the types of beverages and energy intakes. The Anthropometry, Intake and Energy Balance Study ANIBES is a national survey of diet and nutrition conducted among a representative sample of 2285 healthy participants aged 9-75 years in Spain. Food and beverage intakes were assessed in a food diary over three days. Day and time of beverage consumption were also recorded. On average, TWI was 1.7 L (SE 21.2) for men and 1.6 L (SE 18.9) for women. More than 75% of participants had inadequate TWI, according to European Food Safety Authority (EFSA) recommendations. Mean total energy intake (EI) was 1810 kcal/day (SE 11.1), of which 12% was provided by beverages. Water was the most consumed beverage, followed by milk. The contribution of alcoholic drinks to the EI was near 3%. For caloric soft drinks, a relatively low contribution to the EI was obtained, only 2%. Of eight different types of beverages, the variety score was positively correlated with TWI (r = 0.39) and EI (r = 0.23), suggesting that beverage variety is an indicator of higher consumption of food and drinks. The present study demonstrates that well-conducted surveys such as the ANIBES study have the potential to yield rich contextual value data that can emphasize the need to undertake appropriate health and nutrition policies to increase the total water intake at the population level promoting a healthy Mediterranean hydration pattern.

Domestic food waste drying foresees the significant reduction of household food waste mass through the hygienic removal of its moisture content at source. In this manuscript, a new approach for the development and optimization of an innovative household waste dryer for the effective dehydration of food waste at source is presented. Food waste samples were dehydrated with the use of the heated air-drying technique under different air-drying conditions, namely air temperature and air velocity, in order to investigate their drying kinetics. Different thin-layer drying models have been applied, in which the drying constant is a function of the process variables. The Midilli model demonstrated the best performance in fitting the experimental data in all tested samples, whereas it was found that food waste drying is greatly affected by temperature and to a smaller scale by air velocity. Due to the increased moisture content of food waste, an appropriate configuration of the drying process variables can lead to a total reduction of its mass by 87% w/w, thus achieving a sustainable residence time and energy consumption level. Thus, the development of a domestic waste dryer can be proved to be economically and environmentally viable in the future.

The annual electricity consumption analysis and forecasting of China is one of the important bases of management decision making for power generation groups as well as power policy adjusting for government. The socioeconomic actuality could not offer adequate observations with perfect statistic characters. The partial least squares method is applied to get a linear equation. It could quantificational simulate the relationship between the electricity consumption and its factors. The variables importance analysis method is further adopted to distinguish the explanatory power of all relative factors. The foremost importance of production and consumption in rural area shows that the development of this area should account more for the increasing of electricity consumption. The less explanatory power of the gross domestic product of tertiary industry means the gigantic potential in electricity consumption for the future several years. At last, it calculates the contributions of observations. The results show that the unusual development of real estate and relative industry has affected the usual electricity consumption mode. With the clear away of price bubble in real estate, the increasing speed of electricity consumption will slow down in the recent years.

Video-sharing social media like YouTube provide access to diverse cultural products from all over the world, making it possible to test theories that the Web facilitates global cultural convergence. Drawing on a daily listing of YouTube’s most popular videos across 58 countries, we investigate the consumption of popular videos in countries that differ in cultural values, language, gross domestic product, and Internet penetration rate. Although online social media facilitate global access to cultural products, we find this technological capability does not result in universal cultural convergence. Instead, consumption of popular videos in culturally different countries appears to be constrained by cultural values. Cross-cultural convergence is more advanced in cosmopolitan countries with cultural values that favor individualism and power inequality. PMID:28531228

Passenger car fuel consumption survey

Energy Technology Data Exchange (ETDEWEB)

1984-03-01

This survey originated from a proposal to monitor the fuel consumption and fuel economy of personal use passenger cars operated in Canada. Its purpose is to establish a data base which would contain information on total distance travelled, total amount of fuel consumed, average distance obtained per unit of fuel, total expenditures on fuel, and seasonal fluctuations in fuel consumption and in distance travelled. Among the needs served by this data base are the monitoring of passenger car fuel economy standards and the estimation of pasenger car fuel requirements in conditions involving fuel shortages. Survey methodology is by telephone interview to trace selected vehicles to the registered owners, at which time a fuel purchase diary is then mailed to the principal driver of the car. The results are tabulated on a quarterly basis and to be released as they become available in bulletins similar to this. Data are presented for each province and the total for Canada is given. During the fourth quarter of 1982, it is estimated that there were 7.3 million personal use passenger cars operated in Canada. These cars were driven 28 billion kilometers and consumed 4.3 billion litres of fuel. Their average litres/100 kilometres and the average fuel consumption was 590 litres. 8 tabs.

This paper presents a method to estimate the amount of energy that can be shifted during demand response (DR) activation on domestic refrigerator. Though there are many methods for DR activation like load reduction, load shifting and onsite generation, the method under study is load shifting....... Electric heating and cooling equipment like refrigerators, water heaters and space heaters and coolers are preferred for such DR activation because of their energy storing capacity. Accurate estimation of available regulating power and energy shift is important to understand the value of DR activation...... at any time. In this paper a novel method to estimate the available energy shift from domestic refrigerators with only two measurements, namely fridge cool chamber temperature and compressor power consumption is proposed, discussed and evaluated....

Domestication has altered a variety of traits within the Eurasian perch (Perca fluviatilis), including phenotypic, physiological and behavioral traits of Eurasian perch (Perca fluviatilis). Little is known, however, about the genetic changes between domesticated and wild Eurasian perch. In this study, we assembled a high-quality de novo reference transcriptome and identified differentially expressed genes between wild and domesticated Eurasian perch. A total of 113,709 transcripts were assembled, and 58,380 transcripts were annotated. Transcriptomic comparison revealed 630 differentially expressed genes between domesticated and wild Eurasian perch. Within domesticated Eurasian perch there were 412 genes that were up-regulated including MHCI, MHCII, chia, ighm within immune system development. There were 218 genes including try1, ctrl, ctrb, cela3b, cpa1 and cpb1, which were down-regulated that were associated with digestive processes. Our results indicated domestication drives the changes of immune and digestive system of Eurasian perch. Our study not only provide valuable genetic resources for further studies in Eurasian perch, but also provide novel insights into the genetic basis of physiological changes in Eurasian perch during domestication process.

The growing energy consumption in the residential sector represents about 30% of global demand. This calls for Demand Side Management solutions propelling change in behaviors of end consumers, with the aim to reduce overall consumption as well as shift it to periods in which demand is lower and where the cost of generating energy is lower. Demand Side Management solutions require detailed knowledge about the patterns of energy consumption. The profile of electricity demand in the residential sector is highly correlated with the time of active occupancy of the dwellings; therefore in this study the occupancy patterns in Spanish properties was determined using the 2009–2010 Time Use Survey (TUS), conducted by the National Statistical Institute of Spain. The survey identifies three peaks in active occupancy, which coincide with morning, noon and evening. This information has been used to input into a stochastic model which generates active occupancy profiles of dwellings, with the aim to simulate domestic electricity consumption. TUS data were also used to identify which appliance-related activities could be considered for Demand Side Management solutions during the three peaks of occupancy. -- Highlights: •Active occupancy profiles of Spanish dwellings has been obtained and modeled from Time Use Survey data. •Occupancy profiles resulting from the model can be used to model domestic energy consumption. •The presence of three peaks of active occupation was verified, which coincide with morning, noon and evening. •Manual and incentive-based DSM programmes are considered the most suitable for Spanish dwellings. •TV electricity consumption becomes important at aggregate level

There has been great concern about the large amounts of garbage produced by domestic households in the modern world. One of the major sources of dioxins (PCDDs, PCDFs, and coplanar PCBs) in the environment is the combustion of domestic waste materials. Exhaust gases from an incinerator, in which mixtures of 67 food items--including fruits, vegetables, pasta, seafoods, meats, and processed foods and seasoned foods--were analyzed for dioxins. Gases collected at the chimney port (9.15 ng/g) contained less total dioxins than those collected at the chamber port (29.1 ng/g). The levels of Cl1-Cl6-PCDDs and Cl1-Cl5-PCDFs were much lower in the gas collected at the chimney port than in the gas collected at the chamber port. The levels of Cl7-Cl8-PCDDs and Cl6-Cl8-PCDFs were higher in the gas collected at the chimney port than in the gas collected at the chamber port. A total of Cl4-Cl8-PCDDs (1.84-3.04 ng/g) comprised over 80% of the total PCDDs formed (2.24-4.00 ng/g). Total PCDFs (16.2-22.6 ng/g) comprised 78-86% of the total dioxins formed (18.9-29.1 ng/g). The PCDFs formed in the greatest amounts were M1CDFs (9.68-10.7 ng/g). Mixtures of commonly consumed food items produced ppb levels of total dioxins in exhaust gases upon combustion, suggesting that incineration of domestic food wastes is one of the sources of dioxins in the environment. A mixture containing some seasoned foods, such as mayonnaise spread on bread, produced more dioxins (29.1 ng/g) than a mixture without seasoned foods did (18.9 ng/g).

High-throughput sequencing and mutagenesis to accelerate the domestication of Microlaena stipoides as a new food crop.

Directory of Open Access Journals (Sweden)

Frances M Shapter

Full Text Available Global food demand, climatic variability and reduced land availability are driving the need for domestication of new crop species. The accelerated domestication of a rice-like Australian dryland polyploid grass, Microlaena stipoides (Poaceae, was targeted using chemical mutagenesis in conjunction with high throughput sequencing of genes for key domestication traits. While M. stipoides has previously been identified as having potential as a new grain crop for human consumption, only a limited understanding of its genetic diversity and breeding system was available to aid the domestication process. Next generation sequencing of deeply-pooled target amplicons estimated allelic diversity of a selected base population at 14.3 SNP/Mb and identified novel, putatively mutation-induced polymorphisms at about 2.4 mutations/Mb. A 97% lethal dose (LD₉₇ of ethyl methanesulfonate treatment was applied without inducing sterility in this polyploid species. Forward and reverse genetic screens identified beneficial alleles for the domestication trait, seed-shattering. Unique phenotypes observed in the M2 population suggest the potential for rapid accumulation of beneficial traits without recourse to a traditional cross-breeding strategy. This approach may be applicable to other wild species, unlocking their potential as new food, fibre and fuel crops.

National potential of saving of electricity in domestic refrigeration; Potencial nacional de ahorro de electricidad en refrigeracion domestica

In the present paper the evaluation of the potential of saving of electrical energy in Mexico is presented, by means of the substitution of old refrigerators of low efficiency by modern high efficiency ones. This potential is very ample, since the replacement of the old models by new follows a very slow curve, if the economic difficulties of the Mexican families are considered and that, on the other hand, the technology of the domestic refrigerators is so reliable that they have a very long life and they are not easily rejected. In field work have been found refrigerators operating with ages of more than 30 years and still 40. In Mexico, it is estimated that the refrigeration is responsible for around 29% of the of electricity consumption in homes settled in tempered climate and of 14 % in those of warm climate in which air conditioning is used. The proposal of this work is the organization of a governmental program of accelerated substitution of refrigerators that helps to acquire an efficient refrigerator and to reject the old ones. The results indicate that if a total renovation of the park of domestic refrigerators is made, the saving of electrical energy would reach the 5.2 TWh/a which represents the 44.5% of the total consumption of 11.7 TWh in a year. [Spanish] En el presente trabajo se presenta la evaluacion del potencial de ahorro de energia electrica en Mexico, mediante la substitucion de refrigeradores antiguos de baja eficiencia por modernos de alta eficiencia. Este potencial es muy amplio, ya que el reemplazo de los modelos viejos por nuevos sigue una curva muy lenta, si se consideran las dificultades economicas de las familias mexicanas y que, por otro lado, la tecnologia de los refrigeradores domesticos es tan confiable que tienen una vida muy larga y no se desechan facilmente. En trabajos de campo se han encontrado refrigeradores operando con edades de mas de 30 anos y aun 40. En Mexico, se estima que la refrigeracion es responsable de alrededor del

Generalizable occupant-driven optimization model for domestic hot water production in NZEB

Highlights: • Smart meter data for domestic hot water consumption is collected for 46 NZEB. • Reinforcement learning optimizes energy consumed while constrained on user comfort. • Online optimization models learn occupant behaviour and system thermodynamics. • Offline generalizable models calibrate dynamically the storage vessel operation. • Real world application of the active controls resulted in energy savings of 27%. - Abstract: The primary objective of this paper is to demonstrate improved energy efficiency for domestic hot water (DHW) production in residential buildings. This is done by deriving data-driven optimal heating schedules (used interchangeably with policies) automatically. The optimization leverages actively learnt occupant behaviour and models for thermodynamics of the storage vessel to operate the heating mechanism – an air-source heat pump (ASHP) in this case – at the highest possible efficiency. The proposed algorithm, while tested on an ASHP, is essentially decoupled from the heating mechanism making it sufficiently robust to generalize to other types of heating mechanisms as well. Simulation results for this optimization based on data from 46 Net-Zero Energy Buildings (NZEB) in the Netherlands are presented. These show a reduction of energy consumption for DHW by 20% using a computationally inexpensive heuristic approach, and 27% when using a more intensive hybrid ant colony optimization based method. The energy savings are strongly dependent on occupant comfort level. This is demonstrated in real-world settings for a low-consumption house where active control was performed using heuristics for 3.5 months and resulted in energy savings of 27% (61 kW h). It is straightforward to extend the same models to perform automatic demand side management (ADSM) by treating the DHW vessel as a flexibility bearing device.

Background: Inadequate hydration is a public health issue that imposes a significant economic burden. In Spain, data of total water intake (TWI) are scarce. There is a clear need for a national study that quantifies water and beverage intakes and explores associations between the types of beverages and energy intakes. Methods: The Anthropometry, Intake and Energy Balance Study ANIBES is a national survey of diet and nutrition conducted among a representative sample of 2285 healthy participants aged 9–75 years in Spain. Food and beverage intakes were assessed in a food diary over three days. Day and time of beverage consumption were also recorded. Results: On average, TWI was 1.7 L (SE 21.2) for men and 1.6 L (SE 18.9) for women. More than 75% of participants had inadequate TWI, according to European Food Safety Authority (EFSA) recommendations. Mean total energy intake (EI) was 1810 kcal/day (SE 11.1), of which 12% was provided by beverages. Water was the most consumed beverage, followed by milk. The contribution of alcoholic drinks to the EI was near 3%. For caloric soft drinks, a relatively low contribution to the EI was obtained, only 2%. Of eight different types of beverages, the variety score was positively correlated with TWI (r = 0.39) and EI (r = 0.23), suggesting that beverage variety is an indicator of higher consumption of food and drinks. Conclusions: The present study demonstrates that well-conducted surveys such as the ANIBES study have the potential to yield rich contextual value data that can emphasize the need to undertake appropriate health and nutrition policies to increase the total water intake at the population level promoting a healthy Mediterranean hydration pattern.

Uranium exploration in the United States reached its alltime high in 1978 when the chief exploration indicator, surface drilling, totaled 47 million feet. In 1979, however, total drilling declined to 41 million feet, and during the first 8 months of 1980 the trend continued, as surface drilling was 27% less than for the same period in 1979. The total drilling for 1980 now is expected to be below 30 million feet, far less than the 39.4 million feet planned by industry at the beginning of the year. Falling uranium prices, the uncertainties of future uranium demand, rising costs, and the possibility of stiff foreign competition are the prime causes for the current reduction in domestic uranium exploration. Uranium exploration in the United States continues to be concentrated in the vicinity of major producing areas such as the San Juan Basin, Wyoming Basins, Texas Coastal Plain, Paradox Basin, and northeastern Washington, and in areas of recent discoveries including the Henry Mountains, Utah, the McDermitt caldera in Nevada and Oregon, and central Colorado. The distributions, by location, of total surface drilling for 1979 and the first half of 1980 are presented

Biomass is widely used as energy source in rural households in India. Biomass samples and socio-economic data have been collected at district level in the rural areas of Indo-Gangetic plain (IGP), India to determine the emissions of trace gases and aerosols from domestic fuels. Dung cake, fuelwood and crop residue are main sources of energy in rural areas of the IGP. Dung cake is the major domestic fuel (80-90%) in the rural areas of Delhi, Punjab, Haryana, Uttar Pradesh, Bihar and West Bengal, whereas, 99% of rural households in Uttarakhand use wood as the main energy source. Using crop production data and usage of crop residues as energy, new consumption values have been estimated (21.13 Mt). Present information on the domestic fuel usage would be helpful in determining budgets estimates of trace gases and aerosols for India. (author)

Full Text Available Several components of dairy products have been linked to earlier menarche.This study assessed whether positive associations exist between childhood milk consumption and age at menarche or the likelihood of early menarche (<12 yrs in a U.S sample. Data derive from the National Health and Nutrition Examination Survey (NHANES 1999-2004. Two samples were utilized: 2657 women age 20-49 yrs and 1008 girls age 9-12 yrs. In regression analysis, a weak negative relationship was found between frequency of milk consumption at 5-12 yrs and age at menarche (daily milk intake β = -0.32, P<0.10; "sometimes/variable milk intake" β = -0.38, P<0.06, each compared to intake rarely/never. Cox regression yielded no greater risk of early menarche among those who drank milk "sometimes/varied" or daily vs. never/rarely (HR: 1.20, P<0.42, HR: 1.25, P<0.23, respectively. Among the 9-12 yr olds, Cox regression indicated that neither total dairy kcal, calcium and protein, nor daily milk intake in the past 30 days contributed to early menarche. Girls in the middle tertile of milk intake had a marginally lower risk of early menarche than those in the highest tertile (HR: 0.6, P<0.06. Those in the lowest tertiles of dairy fat intake had a greater risk of early menarche than those in the highest (HR: 1.5, P<0.05, HR: 1.6, P<0.07, lowest and middle tertile, respectively, while those with the lowest calcium intake had a lower risk of early menarche (HR: 0.6, P<0.05 than those in the highest tertile. These relationships remained after adjusting for overweight or overweight and height percentile; both increased the risk of earlier menarche. Blacks were more likely than Whites to reach menarche early (HR: 1.7, P<0.03, but not after controlling for overweight.There is some evidence that greater milk intake is associated with an increased risk of early menarche, or a lower age at menarche.

2006-12-01

This comprehensive, illustrated report for the Swiss Federal Office of Energy (SFOE) takes a look at the results of a study with respect to industrial energy consumption which provided scenarios for future Swiss energy consumption. Four scenarios were elaborated: Continuation of present policy, increased co-operation between state and industry, more ambitious energy policy priorities and a scenario with even more ambitious goals - the so-called '2000 Watt Society'. For each of these scenarios several variants and a selection of sub-variants were defined, including increased prices, higher gross domestic product GDP, warmer climate and various carbon levies. The specific energy consumption of 16 different industrial sectors is examined and the effects of the various scenarios on several factors are considered. Data and results are presented in tabular and graphical form. Various measures that could influence energy consumption are listed and discussed, as are the modelling methods employed and the plausibility of the results obtained

Full Text Available One of the manifestations of climate change is increase.in ambient air temperature usually referred to as global warming. For sustainable development in a country, there is need to identify impacts of climate change and the necessary adaptation and mitigation strategies to adopt. To simulate the effect of global warming on the power consumption of refrigerators, a (model No. 150 THERMOCOOL refrigerator filled with twenty-five 750cl packaged water bottleswas run in an air-conditioned room, in a room with the air-conditioner switched off and near an oven in a bakery. The electric power consumption of the refrigerator was measured using "Watts up?.net" Watt meter and the ambient temperature was measured using FLUKE temperature/humidity meter. The average hourly energy consumption of the refrigerator operating at mean ambient temperatures of 25.4°C, 30.7oC, 38.8°C were 93.844 Wh, 100.32 Wh and 105.08 Wh respectively. Some possible ways to reduce the increase in power consumption of refrigerators due to global warming include using compressors of higher efficiency and condensers of greater effectiveness.

Full Text Available As the most common neurodegenerative diseases, Alzheimer’s disease (AD and Parkinson’s disease (PD are two of the main health concerns for the elderly population. Recently, microRNAs (miRNAs have been used as biomarkers of infectious, genetic, and metabolic diseases in humans but they have not been well studied in domestic animals. Here we describe a computational biology study in which human AD- and PD-associated miRNAs (ADM and PDM were utilized to predict orthologous miRNAs in the following domestic animal species: dog, cow, pig, horse, and chicken. In this study, a total of 121 and 70 published human ADM and PDM were identified, respectively. Thirty-seven miRNAs were co-regulated in AD and PD. We identified a total of 105 unrepeated human ADM and PDM that had at least one 100% identical animal homolog, among which 81 and 54 showed 100% sequence identity with 241 and 161 domestic animal miRNAs, respectively. Over 20% of the total mature horse miRNAs (92 showed perfect matches to AD/PD-associated miRNAs. Pigs, dogs, and cows have similar numbers of AD/PD-associated miRNAs (63, 62, and 59. Chickens had the least number of perfect matches (34. Kyoto Encyclopedia of Genes and Genomes (KEGG pathway analyses suggested that humans and dogs are relatively similar in the functional pathways of the five selected highly conserved miRNAs. Taken together, our study provides the first evidence for better understanding the miRNA-AD/PD associations in domestic animals, and provides guidance to generate domestic animal models of AD/PD to replace the current rodent models.

The emergence of farming during the Neolithic transition, including the domestication of livestock, was a critical point in the evolution of human kind. The goat (Capra hircus) was one of the first domesticated ungulates. In this study, we compared the genetic diversity of domestic goats to that of the modern representatives of their wild ancestor, the bezoar, by analyzing 473 samples collected over the whole distribution range of the latter species. This partly confirms and significantly clarifies the goat domestication scenario already proposed by archaeological evidence. All of the mitochondrial DNA haplogroups found in current domestic goats have also been found in the bezoar. The geographic distribution of these haplogroups in the wild ancestor allowed the localization of the main domestication centers. We found no haplotype that could have been domesticated in the eastern half of the Iranian Plateau, nor further to the east. A signature of population expansion in bezoars of the C haplogroup suggests an early domestication center on the Central Iranian Plateau (Yazd and Kerman Provinces) and in the Southern Zagros (Fars Province), possibly corresponding to the management of wild flocks. However, the contribution of this center to the current domestic goat population is rather low (1.4%). We also found a second domestication center covering a large area in Eastern Anatolia, and possibly in Northern and Central Zagros. This last domestication center is the likely origin of almost all domestic goats today. This finding is consistent with archaeological data identifying Eastern Anatolia as an important domestication center. PMID:19004765

We aimed to determine the level of antimicrobial consumption by adult inpatients at Auckland City Hospital (Auckland, New Zealand) and to compare our findings with those in other developed nations. We used the computerised records of the central Auckland District Health Board (ADHB) pharmacy to measure the amount of antimicrobials dispensed to inpatients (excluding psychiatric units, day stay units and outpatient clinics) during 2006 to 2009. The total weight of each antimicrobial dispensed was used to determine the number of defined daily doses (DDDs) dispensed. The Information Management and Technical Services department of ADHB provided data on the number of admissions and inpatient days, and these data, together with information from the 2006 census, were used to calculate antimicrobial consumption for adult inpatients measured in DDDs/100 admissions, DDDs/100 inpatient days and DDDs/1000 population. Total antimicrobial consumption by adult inpatients increased from 74 DDDs/100 inpatient days in 2006 to 80.3 DDDs/100 inpatient days in 2009. The level of consumption did not vary greatly with the season. The total level of consumption was very similar to that seen in adult inpatients in hospitals in Australia and Scandinavian countries. The level of consumption of fluoroquinolones, third or fourth generation cephalosporins, carbapenems and vancomycin (antimicrobial classes that are not available for unrestricted use in Auckland City Hospital) was comparable to or less than that seen in adult inpatients in hospitals in Australia or Scandinavian countries. Beta-lactamase susceptible penicillins (such as benzyl penicillin and phenoxymethylpenicillin) comprised a relatively small proportion of total penicillin use and beta-lactamase inhibitor combinations (predominantly amoxicillin/clavulanate) a relatively large proportion of total penicillin use, when compared with Scandinavian hospitals. The antimicrobial stewardship programme at Auckland City Hospital has

In this study, the radiative properties of the surfaces of an electric oven were investigated. Using experimental data related to an oven-like enclosure, a novel combination of surface properties was developed. Three different surface emissivity combinations were analysed experimentally: low-emissivity, high emissivity (black-coated), and hybrid emissivity. The term "hybrid emissivity design" here corresponds to an enclosure with some high emissive and some low-emissive surfaces. The experiments were carried out according to the EN 50304 standard. When a brick (load) was placed in the enclosure, the view factors between its surfaces were calculated with the Monte Carlo method. These and the measured surface temperatures were then used to calculate the radiative heat fluxes on the surfaces of the load. The three different models were compared with respect to energy consumption and baking time. The hybrid model performed best, with the highest radiative heat transfer between the surfaces of the enclosure and the load and minimum heat loss from the cavity. Thus, it was the most efficient model with the lowest energy consumption and the shortest baking time. The recent European Union regulation regarding the energy labelling of domestic ovens was used.

Adult Clonorchis sinensis not only occurs in human hepatic duct, but also in the liver, gallbladder and bile ducts of animals, including dogs and cats, thus causing clonorchiasis-one of important parasitic zoonoses. In present study, we dissected a domestic cat in which a total of 736 pieces of trematodes, identified as Clonorchis sinensis , were detected in the liver and cholecyst. The findings indicate that Clonorchis sinensis may be endemic in domestic animals in Wuhu area, and observe our awareness in prevention of the parasites in house pets.

The dietary intake of arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) was studied among young German children with different food consumption behaviour (consumption of own grown foodstuffs and of products from the supermarket). The study area comprised an industrialized and a rural area of West Germany. Dietary intake of contaminants was measured by the duplicate method according to the WHO guideline. A total 588 duplicate portions were collected daily from 84 individuals between May and September 1998. Intake of food groups was calculated from dietary records. Determination of As, Cd, Hg, and Pb was performed following high-pressure digestion of lyophilized samples by atomic absorption spectrometry (AAS). Geometric mean weekly intake [μg/(kg bw .week)] was as follows: As 1.4, Cd 2.3, Hg 0.16, and Pb 5.3. Geometric mean intake corresponded to the percentage of the provisional tolerable weekly intake (PTWI) as follows: As 9.7%, Cd 32%, Hg 3.3%, Pb 21%. As and Hg intake were mainly influenced by fish consumption. The amount of cereals and bakery wares mainly determined the Cd and Pb intake. Children living in the industrialized area with a substantial food consumption of own grown vegetables or products from domestic animals products had no increased dietary intake of the metals

To investigate outpatient consumption of antibiotics during the 2006-2010 period in the City of Zagreb and compare it with other European countries. Data on outpatient consumption of antibiotics were obtained from all pharmacies in the City of Zagreb. Based on the data obtained, the number of defined daily doses per 1000 inhabitants per day (DDDs/TID) were calculated for each ATC subgroup. Drug Utilization 90% (DU90%) method and ratio indicators were used for the assessment of drug prescribing quality. During the period of five years total antibiotics consumption has declined from 37.38 DDDs/TID in 2006 to 33.28 DDDs/ TID in 2010. The most frequently prescribed subgroup was penicillins (J01C). DU90% segment included 10 out of a total of 32 antibiotics in the year 2006 and 10 out of a total of 23 antibiotics in the year 2010. Leading position in the consumption, in 2006 and 2010, was held by broad-spectrum antibiotics, moreover their consumption increased in 2010. Consumption of antibiotics in Zagreb is still very high and is similar to the consumption in European countries with the highest consumption of antibiotics. Reduced consumption of narrow-spectrum antibiotics and unjustified increase in the consumption of broad-spectrum antibiotics suggess that physicians do not follow clinical guidelines.

Full Text Available Background and objectives: A transversus abdominis plane block is a peripheral block method that has been used successfully for pain relief after total abdominal hysterectomy. However, the effects of the combination of the transversus abdominis plane block and general anesthesia on analgesic and anesthetic requirements remain unclear. This randomized placebo-controlled study is aimed to evaluate the effects of transversus abdominis plane block on analgesic and anesthetic consumption during total abdominal hysterectomy under general anesthesia. Methods: Sixty-six women undergoing total abdominal hysterectomy were randomized into two groups to receive general anesthesia alone (control group or with transversus abdominis plane block using 20 mL of 0.25% bupivacaine (transversus abdominis plane group. Intraoperative remifentanil and sevoflurane consumption were recorded. We also evaluated the postoperative pain, nausea, quality of recovery scores and rescue analgesic requirement during postoperative 24 hours. Results: The total remifentanil and sevoflurane consumption is significantly lower in transversus abdominis plane group; respectively mean (SD 0.130 (0.25 vs. 0.094 (0.02 mcg.kg−1.min−1; p < 0.01 and 0.295 (0.05 vs. 0.243 (0.06 mL.min−1; p < 0.01.

The chile of Mesoamerica, Capsicum annuum, is one of five domesticated chiles in the Americas. Among the chiles, it varies the most in size, form, and color of its fruits. Together with maize, C. annuum is one of the principal elements of the neotropical diets of Mesoamerican civilizations. Despite the great economic and cultural importance of C. annuum both worldwide and in Mexico, however, very little is known about its geographic origin and number of domestications. Here we sampled a total of 80 accessions from Mexico (58 semiwild and 22 domesticated) and examined nucleotide sequence diversity at three single- or low-copy nuclear loci, Dhn, G3pdh, and Waxy. Across the three loci, we found an average reduction of ca. 10% in the diversity of domesticates relative to semiwild chiles and geographic structure within Mexican populations. The Yucatan Peninsula contained a large number of haplotypes, many of which were unique, suggesting an important region of chile domestication and center of diversity. The present sampling of loci did not conclusively resolve the number and location of domestications, but several lines of evidence suggest multiple independent domestications from widely distributed progenitor populations.

Acute and chronic radiation syndrome in domestic animals

Nuessel, M.

1974-11-01

The paper reports on the incidence and the clinical picture of the radiation syndrome in domestic animals, especially in pigs which are often used in animal experiments. The following parameters which influence the radiation reaction are discussed: type of irradiation (whole-body, partial-body and local irradiation), mean lethal radiation dose, radiation quality and RBE, age and individual radiosensitivity. The auther then describes the various symptoms of the radiation syndrome and the lesions which lead to death (death due to intestinal lesions, death following changes in the central nervous system). The next few chapters treat the symptoms manifested after chronic and internal irradiation. The paper closes with some remarks on the usability of irradiated animals for human consumption.

Clinch, J. Peter; Healy, John D.

2003-01-01

There are a number of stimuli behind energy efficiency, not least the Kyoto Protocol. The domestic sector has been highlighted as a key potential area. Improving energy efficiency in this sector also assists alleviating fuel poverty, for research is now demonstrating the strong relationship between poor domestic thermal efficiency, high fuel poverty and poor health and comfort status. Previous research has modelled the energy consumption and technical potential for energy saving resulting from energy-efficiency upgrades in this sector. However, there is virtually no work evaluating the economic benefit of improving households' thermal comfort post-retrofit. This paper does this for Ireland using a computer-simulation program. A dynamic modelling process is employed which projects into the future predicting the extent to which energy savings are forgone for improvements in comfort

Evidence suggests that adult per-capita alcohol consumption, as estimated from self-reports of nationally representative surveys, underestimates 'true' consumption, as measured as the sum of recorded and unrecorded consumption. The proportion of total adult alcohol per capita reported in representative surveys is usually labelled 'coverage'. The aim of the present paper was to estimate coverage for South Africa under different scenarios of alcohol use assessment and 'true' consumption. Five nationally representative surveys from South Africa were used to estimate the prevalence of drinking and the grams per day among current drinkers. All surveys used a complex multi-stage sampling frame that was accounted for by using survey weights. The total (recorded and unrecorded), the recorded and the adjusted total adult per-capita alcohol consumption in South Africa served as different estimates of the 'true' consumption. South Africa. Alcohol use information was assessed on a total of 8115, 16 398 and 13 181 adults (15 years or older) in surveys from the years 2003, 2005 and 2008, respectively. Two surveys in 2012 included 27 070 and 18 688 adults. Coverage of the alcohol use reported in the surveys was calculated, compared with the 'true' adult per-capita alcohol. The survey data covered between 11.8% [2005; 95% uncertainty interval (UI) = 9.3-16.2%)] and 19.4% (2003; 95% UI = 14.9-24.2%) of the total alcohol used per capita. The highest coverage of 27.9% (95% UI = 22.4-36.8%) was observed when looking only at recorded alcohol in 2003. Evidence from five nationally representative surveys assessing alcohol use suggests that less than 20% of the total adult per-capita alcohol consumption in South Africa is reported in surveys. © 2016 Society for the Study of Addiction.

Full Text Available The research was conducted in a dairy WWTP located in north-eastern Poland with the average flow of 546 m3d-1 and PE 11500 in 2016. Energy consumption was measured with the help of Lumel 3-phase network parameter transducers installed within the plant. The modeling was conducted based on the quantity and quality of raw sewage, after its screening, averaging and dissolved air flotation. The following parameters were determined: BOD5, COD. N-total and P-total. During the research period. 15 measurement series were carried out. Pollution loads removed in primary treatment varied from 167.0 to 803.5 kgO2d-1 and 1205.9 to 10032 kgO2d-1 for BOD5 and COD respectively. The energy consumption share during dairy pretreatment in relation to the total energy consumption was in the range from 13.8 to 28.5% with the mean value of 18.7% during the research period. Energy consumption indicators relating to removed pollution loads for primary treatment were established with the mean values of 0.74 and 0.83 kWhkg-1d-1 for BOD5 and COD respectively. An attempt was made to determine the influence of raw sewage characteristics and pretreatment efficiency on energy consumption of the object. A model of energy consumption during pretreatment was estimated according to the experimental data obtained in the research period. It was modeled using the linear regression model and principal component analysis.

Oil consumption plays a vital role in socio-economic development of most countries. This study presents a flexible fuzzy regression algorithm for forecasting oil consumption based on standard economic indicators. The standard indicators are annual population, cost of crude oil import, gross domestic production (GDP) and annual oil production in the last period. The proposed algorithm uses analysis of variance (ANOVA) to select either fuzzy regression or conventional regression for future demand estimation. The significance of the proposed algorithm is three fold. First, it is flexible and identifies the best model based on the results of ANOVA and minimum absolute percentage error (MAPE), whereas previous studies consider the best fitted fuzzy regression model based on MAPE or other relative error results. Second, the proposed model may identify conventional regression as the best model for future oil consumption forecasting because of its dynamic structure, whereas previous studies assume that fuzzy regression always provide the best solutions and estimation. Third, it utilizes the most standard independent variables for the regression models. To show the applicability and superiority of the proposed flexible fuzzy regression algorithm the data for oil consumption in Canada, United States, Japan and Australia from 1990 to 2005 are used. The results show that the flexible algorithm provides accurate solution for oil consumption estimation problem. The algorithm may be used by policy makers to accurately foresee the behavior of oil consumption in various regions.

Prior research suggests that homicide cases involving familial offenders and victims are subject to a "domestic discount" that reduces sentencing severity. However, the operation of a domestic discount in regard to death penalty sentencing has been rarely examined. The current research uses a near-population of jury decisions in capital murder trials conducted in North Carolina from 1991 to 2009 (n = 800), and a series of logistic regression analyses to determine whether there is (a) a direct effect between offender-victim relationship (e.g., domestic, friend/acquaintance, and stranger) and jury decision making, and/or (b) whether domestic offender-victim relationship (as well as other offender-victim relationships) moderates the effect of legal and extralegal case characteristics on jury assessment of the death penalty. Our findings revealed no empirical support for a "domestic discount" whereby juries are less likely to impose death sentences in cases involving domestic homicides. However, substantial differences in predictors of death sentencing were found across offender-victim dyads; most notably, domestic homicide cases demonstrated the most legalistic model of jury decisions to impose death sentences.

Full Text Available The paper presents the results of researching wood fuels consumption in households in Montenegro in the heating season 2011/2012. The research was conducted in the period October-November 2012 on the sample of 5% of the total number of households which stated to use solid fuels for heating purposes in the 2011 census. Results of the conducted researches on the presence and amounts of fuels consumed in households in Montenegro showed that total firewood consumption in the heating season 2011/2012 (both urban and rural households was 703,571 m3. Wood consumption is the lowest in the households in the municipalities in the coastal zone, it is somewhat higher in central zone and the highest in the zone on the north of Montenegro. Average wood consumption in households in the coastal zone municipalities is 3.79 m3, in the central zone it is 5.02 m3 and on the north of Montenegro it is 6.74 m3/household. Observed on the level of Montenegro, average firewood consumption per household was 5.49 m3 and as such it best represents relatively low consumption level in the coastal zone and high consumption level on the north of Montenegro. Compared to the neighboring countries, average firewood consumption per household in Montenegro in the amount of 5.49 m3 is significantly lower than the average consumption in Serbia which is 7.3 m3/household as well as in Slovenia in the amount of 6.5 m3.

This paper investigates the dynamic causal relationship between energy consumption and economic growth in Lebanon over the period 1980–2009. Within a bivariate framework, imposed on us due to data limitations, and in an effort to increase the robustness of our results, we employ a variety of causality tests, namely, Hsiao, Toda-Yamamoto, and vector error correction based Granger causality tests. We find strong evidence of a bidirectional relationship both in the short-run and in the long-run, indicating that energy is a limiting factor to economic growth in Lebanon. From a policy perspective, the confirmation of the feedback hypothesis warns against the use of policy instruments geared towards restricting energy consumption, as these may lead to adverse effects on economic growth. Consequently, there is a pressing need to revise the current national energy policy that calls for a 5% energy conservation target. Also, to shield the country from external supply shocks, given its substantial dependence on energy imports, policymakers should emphasize the development of domestic energy resources. Further, the most pertinent implication is that relaxing the present electric capacity shortages should be made a national priority, in view of its potential positive effect on the economy. - Highlights: ► We investigate the energy-GDP nexus for Lebanon. ► Evidence of a bidirectional relationship both in the short- and the long-run is found. ► Reducing outages by expanding electric capacity should thus be prioritized. ► The energy plan calling for a 5% reduction in energy consumption needs to be revised. ► Development of domestic energy sources will help in mitigating energy supply shocks.

The crisis of gasoline consumption in the Iran's transportation sector

2008-01-01

Fossil fuels have the greatest share in supplying the world's energy demands. Regarding the limited natural resources, fuel consumption management and energy planning in the end-user sectors are two great matters of importance. Among the fossil fuels, gasoline is the principal fuel for light-duty vehicles. In Iran, fuel consumption, especially that of gasoline, has increased sharply with the growth rate of 10.2% for the year 2006 in comparison with that in 2005, turning into a big crisis in the recent years. On the other hand, enormous subsidies for importing 40% of domestic demands, which have reached more than 10 billion US$, are too much to be supplied. In this study, we have assessed the gasoline consumption, production, import and prices; reviewed main causes of the tremendous growth rate of consumption, current conservation policies and their advantages or disadvantages (SWOT analysis); proposed short- to long-term solutions and strategies for efficient gasoline consumption management; and finally, current strategies and proposed solutions are analyzed and evaluated. A foregone conclusion strongly suggests that not only the low price of motor gasoline but also mass production of vehicles with the conventional technology, likewise, affects motor gasoline demand. A second conclusion is that gasoline crisis in Iran has no straight solution, and that fundamental strategies and policies are needed to solve the problem. (author)

Background & objectives: Domestic violence is identified as a public heath problem. It is associated with adverse maternal health. This study examined the prevalence and determinants of domestic violence among women in urban slums of Mumbai, India. Methods: A community based cross-sectional household survey was carried out among eligible women for the study during September 2012 to January 2013. A total of 1137 currently married women aged 18-39 yr with unmet need for family planning and having at least one child were selected using cluster systematic random sampling from two urban slums. Information on socio-demographic, reproductive and domestic violence was collected through face-to-face interview using a pretested structured questionnaire after obtaining informed written consent. Bivariate and multivariate analyses were carried out to find the socio-demographic factors associated with ever experienced domestic violence among women. Results: The prevalence of women ever experiencing domestic violence in the community was 21.2 per cent. Women whose husband consumed alcohol [RR: 2.17, (95% CI: 1.58-2.98)] were significantly at an increased risk of ever experiencing domestic violence than their counterparts. Risk of domestic violence was twice [RR: 2.00, (95% CI: 1.35-2.96)] for women who justified wife beating than women who did not justify wife beating. Interpretation & conclusions: The findings showed that domestic violence was prevalent in urban slums. Factors like early marriage, working status, justified wife beating and husbands use of alcohol were significantly associated with domestic violence. PMID:26205021

To preserve environmental and human health, improved treatment processes are needed to reduce nutrients, microbes, and emerging chemical contaminants from domestic wastewater prior to discharge into the environment. Electrocoagulation (EC) treatment is increasingly used to treat industrial wastewater; however, this technology has not yet been thoroughly assessed for its potential to reduce concentrations of nutrients, a variety of microbial surrogates, and personal care products found in domestic wastewater. This investigation's objective was to determine the efficiency of a benchtop EC unit with aluminum sacrificial electrodes to reduce concentrations of the aforementioned biological and chemical pollutants from raw and tertiary-treated domestic wastewater. EC treatment resulted in significant reductions (p < 0.05, α = 0.05) in phosphate, all microbial surrogates, and several personal care products from raw and tertiary-treated domestic wastewater. When wastewater was augmented with microbial surrogates representing bacterial, viral, and protozoan pathogens to measure the extent of reduction, EC treatment resulted in up to 7-log10 reduction of microbial surrogates. Future pilot and full-scale investigations are needed to optimize EC treatment for the following: reducing nitrogen species, personal care products, and energy consumption; elucidating the mechanisms behind microbial reductions; and performing life cycle analyses to determine the appropriateness of implementation.

Domestic work count! Characteristics and transformations of the domestic service in Spain

2015-03-01

Full Text Available This paper explores the characteristics of and transformations that Spanish domestic service has undergone in the since 2000. The paper also analyzes the domestic service’s contribution to the Spanish economy since the beginning of the country’s economic crisis. Relying on quantitative analysis of the domestic work data from the Active Population Survey, the most relevant changes identified are the increase of its demand and the consolidation of migrants workers in it. The paper also looks at the tasks carried out in the households of employers. The recent conversion of the domestic services in a nonprofessional care sector seems to mitigate the burden of personal care work that Spanish families aim to provide to their older relatives. This transformation of domestic work into care work has changed some traditional features of this occupation: the outcomes of qualitative data show changes in the intensification of the tasks carried out, a tendency to higher male workers, a reappearance of live-in workers, and key modifications in the relationship between employer families and employees. Finally, this paper incorporates a short assessment of Real Royal Decree 1620/2011 (which regulates domestic service and Law 39/2006 (Law on the Promotion of Personal Autonomy and Care for Dependent Persons to analyze which is the legal space delegate to the labor category related with the non-professional caregivers in private homes.

2012-08-01

International students form a significant proportion of students studying within universities in Western countries. The quality of life perceptions of international medical students in comparison with domestic medical students has not been well documented. There is some evidence to suggest that international medical students may have different educational and social experiences in relation to their domestic peers. This study investigates the levels of quality of life experienced by international and domestic students studying medicine. A total of 548 medical students completed the abbreviated version of the World Health Organization Quality of Life questionnaire. The focus of the analysis was to evaluate differences between international and domestic students in their early clinical years. The responses were analysed using multivariate analysis of variance methods. International medical students are experiencing lower social and environmental quality of life compared with domestic peers. International medical students in New Zealand have expressed quality of life concerns, which likely have an impact on their academic achievement, feelings of wellness, acculturation, and social adaptation. The findings reinforce the need for creating stronger social networks and accessible accommodation, as well as developing systems to ensure safety, peer mentorship and student support.

Families that experience domestic violence and parental substance misuse are disproportionately involved with the child welfare system. Prior research suggests that child protective services (CPS) caseworkers are more likely to substantiate maltreatment allegations when domestic violence and parental substance misuse are identified during the investigation, pointing to one possible mechanism for this disproportionate involvement. While previous studies have relied on nationally representative data sets, the current study used administrative records from a large Midwestern child welfare agency that accounts for state-level variation in child welfare policy and practice. A total of 501,060 substantiation decisions made between 2009 and 2013 were examined to assess the influence of caseworker-perceived domestic violence and parental substance misuse on the decision to substantiate reported maltreatment. Results from multilevel modeling suggest that the identification of domestic violence and parental substance misuse during an investigation significantly increased the probability that an allegation would be substantiated. The implication of these findings for child welfare practice are considered in light of the fact that many child welfare agencies do not consider exposure to domestic violence and parental substance misuse in and of themselves to constitute child maltreatment.

Background: Increasing dietary sodium drives the thirst response. Because sugar-sweetened beverages (SSBs) are frequently consumed by children, sodium intake may drive greater consumption of SSBs and contribute to obesity risk. Objective: We examined the association between dietary sodium, total fluid, and SSB consumption in a nationally representative sample of US children and adolescents aged 2–18 y. Design: We analyzed cross-sectional data from NHANES 2005–2008. Dietary sodium, fluid, and SSB intakes were assessed with a 24-h dietary recall. Multiple regression analysis was used to assess associations between sodium, fluid, and SSBs adjusted for age, sex, race-ethnic group, body mass index (BMI), socioeconomic status (SES), and energy intake. Results: Of 6400 participants, 51.3% (n = 3230) were males, and the average (±SEM) age was 10.1 ± 0.1 y. The average sodium intake was 3056 ± 48 mg/d (equivalent to 7.8 ± 0.1 g salt/d). Dietary sodium intake was positively associated with fluid consumption (r = 0.42, P sodium is positively associated with fluid consumption and predicted SSB consumption in consumers of SSBs. The high dietary sodium intake of US children and adolescents may contribute to a greater consumption of SSBs, identifying a possible link between dietary sodium intake and excess energy intake.

2010-01-01

Estimation of fuel (gasoline and diesel) consumption for vehicles in China under different long-term energy policy scenarios is presented here. The fuel economy of different vehicle types is subject to variation of government regulations; hence the fuel consumption of passenger cars (PCs), light trucks (Lts), heavy trucks (Hts), buses and motor cycles (MCs) are calculated with respect to (i) the number of vehicles, (ii) distance traveled, and (iii) fuel economy. On the other hand, the consumption rate of alternative energy sources (i.e. ethanol, methanol, biomass-diesel and CNG) is not evaluated here. The number of vehicles is evaluated using the economic elastic coefficient method, relating to per capita gross domestic product (GDP) from 1997 to 2007. The Long-range Energy Alternatives Planning (LEAP) system software is employed to develop a simple model to project fuel consumption in China until 2030 under these scenarios. Three energy consumption decrease scenarios are designed to estimate the reduction of fuel consumption: (i) 'business as usual' (BAU); (ii) 'advanced fuel economy' (AFE); and (iii) 'alternative energy replacement' (AER). It is shown that fuel consumption is predicted to reach 992.28 Mtoe (million tons oil equivalent) with the BAU scenario by 2030. In the AFE and AER scenarios, fuel consumption is predicted to be 734.68 and 600.36 Mtoe, respectively, by 2030. In the AER scenario, fuel consumption in 2030 will be reduced by 391.92 (39.50%) and 134.29 (18.28%) Mtoe in comparison to the BAU and AFE scenarios, respectively. In conclusion, our models indicate that the energy conservation policies introduced by governmental institutions are potentially viable, as long as they are effectively implemented.

Domesticated animals play an important role in the life of humanity. All these domesticated animals undergo same process, first domesticated from wild animals, then after long time natural and artificial selection, formed various breeds that adapted to the local environment and human needs. In this process, domestication, natural and artificial selection will leave the selection signal in the genome. The research on these selection signals can find functional genes directly, is one of the most important strategies in screening functional genes. The current studies of selection signal have been performed in pigs, chickens, cattle, sheep, goats, dogs and other domestic animals, and found a great deal of functional genes. This paper provided an overview of the types and the detected methods of selection signal, and outlined researches of selection signal in domestic animals, and discussed the key issues in selection signal analysis and its prospects.

Objective Violence against women, particularly against pregnant women, is increasingly being recognized as a significant problem around the world. Limited studies were found about domestic violence among pregnant women. The aim of this study was to determine the prevalence of domestic violence during pregnancy and the factors affecting it. Material and Methods This prospective study was conducted at the Department of Obstetrics and Gynecology, between January 2012 and April 2013. A total of 1349 pregnant women, irrespective of age and socioeconomic status, were interviewed using a questionnaire in the local language. Results The incidence of domestic violence in this study was 2.37%. The mean age of women who reported violence was 29.06±5.53 years. Age, marriage duration, gravidity, parity, educational level, partner’s educational level, and monthly income exerted no significant influences on women who experienced domestic violence during their pregnancies (p>0.05). Women who resided in the same houses with large extended families were at significantly higher risk of domestic violence during pregnancy in comparison with the pregnant women who lived within a core family (p=0.018). Conclusion Domestic violence during pregnancy is a potential public health problem. Education, improvements in economic autonomy, and society’s attitudes may reduce domestic violence. Health-care providers should increase their awareness of risk factors to protect women from domestic violence. PMID:24976770

Lean consumption.

Womack, James P; Jones, Daniel T

2005-03-01

During the past 20 years, the real price of most consumer goods has fallen worldwide, the variety of goods and the range of sales channels offering them have continued to grow, and product quality has steadily improved. So why is consumption often so frustrating? It doesn't have to be--and shouldn't be--the authors say. They argue that it's time to apply lean thinking to the processes of consumption--to give consumers the full value they want from goods and services with the greatest efficiency and the least pain. Companies may think they save time and money by off-loading work to the consumer but, in fact, the opposite is true. By streamlining their systems for providing goods and services, and by making it easier for customers to buy and use those products and services, a growing number of companies are actually lowering costs while saving everyone time. In the process, these businesses are learning more about their customers, strengthening consumer loyalty, and attracting new customers who are defecting from less user-friendly competitors. The challenge lies with the retailers, service providers, manufacturers, and suppliers that are not used to looking at total cost from the standpoint of the consumer and even less accustomed to working with customers to optimize the consumption process. Lean consumption requires a fundamental shift in the way companies think about the relationship between provision and consumption, and the role their customers play in these processes. It also requires consumers to change the nature of their relationships with the companies they patronize. Lean production has clearly triumphed over similar obstacles in recent years to become the dominant global manufacturing model. Lean consumption, its logical companion, can't be far behind.

Linkage of food consumption and export to ammonia emissions in Canada and the overriding implications for mitigation

Sheppard, S. C.; Bittman, S.

2015-02-01

Ammonia (NH3) emissions from agriculture to the atmosphere, along with emissions of other pollutants from a variety of sources, are of concern to agriculture worldwide. National emissions from agricultural sources in Canada are linked to domestic consumption and export demand for agricultural products. The onus to limit emissions is often directed to the producers, but the marketplace and consumer are also responsible for the environmental impact of their choices. This objective of this study was to quantitatively link agricultural NH3 emissions to per person consumption of food and protein and to agricultural exports from Canada. There are substantial differences in the NH3 emissions per unit consumed protein among the various food types. As a result, shifts in the Canadian diet have had a large impact on relative per person NH3 emissions. From 1981 to 2006, the total per person protein intake in the Canadian diet increased about 5%, but NH3 emission related to that diet decreased 20%. This is largely related to consumption of less beef, which has a high emission per unit of meat or protein, and more poultry and cereals which have much lower emissions. Although these changes in diet were not because of environmental concerns by the consumers, they had substantial effects on national-level emissions. These consumer driven effects may well exceed the possible effects of best management practices intended to address NH3 emissions at the producer level. Note that the Canadian population has increased 50% from 1981 to 2006 and meat and egg exports increased 570%, so that total emissions from food production in Canada have increased. Our results imply there will be further effects on national NH3 emissions because of dietary and export drivers that are generally outside the scope of agro-environmental policy.

Helga Dís Sigurdardottir

2016-07-01

Full Text Available This paper analyses the use of digital game-based learning (DGBL in schools in Norway. It investigates the types of games used in Norwegian schools and how pupils experience that practice. Digital game-based learning is being widely employed throughout Norway as a result of the increased focus on digital skills in Norwegian education. This paper analyses that development by way of focus group interviews with a total of sixty-four pupils at four schools. Drawing upon domestication and actor-network theory, the paper provides a novel approach to the study of DGBL. The broad empirical investigation into DGBL practices furthermore provides a contribution to scholarly literature on the subject. A noteworthy finding of this study is the diversity of games employed in schools—around 30 different titles— indicating that the choice of games lies at the discretion of individual teachers. Findings from this research show that the domestication of digital game-based learning occurs through the construction of complex game-based learning assemblages. This includes the classroom and home as gaming sites, group work and individual assignments as practices, and PCs and iPads as platforms.

ECONOMETRIC METHODS AND MODELS USED IN THE ANALYSIS OF THE FACTORIAL INFLUENCE OF THE GROSS DOMESTIC PRODUCT GROWTH

Full Text Available Gross Domestic Product is the most representative synthetic indicator that expresses the evolution of the national economy. This macroeconomic indicator is used in the analysis of the level of the national economy, as well as the dynamic evolution of the national economy. In the forecast studies we rely on GDP evolution. In these situations, we might identify the factors of economic growth, and their influence. On the evolution of GDP have influence some factors: employees, labour productivity, the level of technology, investments and foreign direct investment, imports, exports or net exports, total consumption, and so on. We can analyze the data series and graphical representation. Detailed analysis is performed using econometric methods, parameters which express interdependence, meaning and intensity of correlation. Thus, we estimate the economic developments. The authors studied and proposed some econometric models for the analysis of economic growth/forecast. The novelty is that we adapt some econometric models to macroeconomic analysis.

A system of tradable CO2 permits applied to fuel consumption by motorists

International Nuclear Information System (INIS)

Raux, C.; Marlot, G.

2005-01-01

Decentralized transferable permit systems in the transport sector can be of interest with regard to reducing greenhouse gas emissions, in spite of anticipated transaction costs. This paper describes a potential application of a domestic market for car fuel consumption permits. The marginal costs of consumption reduction vary sufficiently according to motorists' residential locations to consider permit exchanges. Economic evaluation of this system shows that there are transfers of surplus between the various groups of motorists according to their residential locations. The central government may lose significant revenues when compared with a conventional fuel tax. Lastly, the issue of transaction costs, the benefits and disadvantages in terms of social acceptability and equity are discussed. (author)

Biofuel is the main source of energy for cooking and heating in Africa. In order to estimate the consumption of this resource at a regional level, a database with a spatial resolution of 1° latitude by 1° longitude of the distribution of the amounts of fuel wood and charcoal annually burned in West Africa has been derived. Chemical emission factors for fuel wood, for charcoal burning, and for charcoal fabrication measured during two field experiments are then used in conjunction with this database to produce a second 1° latitude by 1° longitude database of the emissions due to domestic fires for the region. A comparison of these emissions from domestic fires with those of savanna fires, the dominant form of biomass burning in tropical Africa, shows that the relative contribution of the wood fuel (i.e. fuel wood and charcoal) combustion is important for CH4 (46%), CO (42%), and nonmethane hydrocarbons (NMHC) (44%), less so for CO2 (32%). This source of biomass burning has a different spatial and temporal distribution than that of savanna fires and represents an atmospheric background noise throughout the year, whereas the savanna fires occur during a limited season.

The provision of energy consumption feedback on in-home displays (IHDs) has a prominent role in government strategies for domestic energy demand reduction. Research suggests that IHDs can support energy consumption reduction, but also that engagement with IHDs can be limited to men and is often short-term. In this paper, we draw on research carried out in Smart Communities, a two-year project in which electricity and gas consumption feedback played a key role. This study was distinctive because it was accompanied by a weekly email communications programme and was provided within the context of community action. Project findings suggest that, although by no means panaceas, approaches such as these can support long-term engagement with energy consumption feedback, including by women, and can support behaviour change. - Highlights: • We examine the challenge of householder engagement with energy consumption feedback. • The potential of ‘community action’ and ‘communications’ is explored. • These approaches are shown to support long-term engagement by householders. • These approaches are also shown to support greater engagement by women. • Recommendations for future IHD platforms and smart meter roll-outs are presented.

Estimates of water use at thermoelectric plants were developed by the U.S. Geological Survey based on linked heat and water budgets, and complement reported thermoelectric water withdrawals and consumption. The heat- and water-budget models produced withdrawal and consumption estimates, including thermodynamically plausible ranges of minimum and maximum withdrawal and consumption, for 1,290 water-using plants in the United States for 2010. Total estimated withdrawal for 2010 was about 129 billion gallons per day (Bgal/d), and total estimated consumption was about 3.5 Bgal/d. In contrast, total withdrawal reported by the U.S. Department of Energy, Energy Information Administration (EIA), was about 24 percent higher than the modeled estimates, and total EIA-reported consumption was about 8 percent lower. Most thermoelectric generation in 2010 was not associated with thermodynamically plausible EIA-reported values of both withdrawal and consumption.

Climate is a key driving factor in energy consumption. However, income, vegetation, building mass structure, topography also impact on the amount of energy consumption. In a changing climate, increased temperatures are likely to lead to increased electricity consumption, affecting demand, distribution and generation. Furthermore, as the world population becomes more urbanized, increasing numbers of people will need to deal with not only increased temperatures from climate change, but also from the unintentional modification of the urban climate in the form of urban heat islands. Hence, climate and climate change needs to be taken into account for future urban planning aspects to increase the climate and energy resilience of the community and decrease the future social and economic costs. Geographical Information Systems provide a means to create urban climate maps as part of the urban planning process. Geostatistical analyses linking these maps with demographic and social data, enables a geo-statistical analysis to identify linkages to high-risk groups of the community and vulnerable areas of town and cities. Presently, the climatope classification is oriented towards thermal aspects and the ventilation quality (roughness) of the urban areas but can also be adapted to take into account other structural "environmental factors". This study aims to use the climatope approach to predict areas of potential high electricity consumption in Birmingham, UK. Several datasets were used to produce an average surface temperature map, vegetation map, land use map, topography map, building height map, built-up area roughness calculations, an average air temperature map and a domestic electricity consumption map. From the correlations obtained between the layers it is possible to average the importance of each factor and create a map for domestic electricity consumption to understand the influence of environmental aspects on spatial energy consumption. Based on these results city

Since the 1960s, there has been growing awareness regarding the issue of domestic violence as a form of violence against women, which has been largely influenced by the work of feminist activist and scholars in North America and Europe (Dobash and Dobash 1992). Other terms have been used to describe the same phenomenon, including domestic abuse, spousal abuse, wife battering, marital violence, intimate partner violence. Though there is no doubt that this problem has existed for much more than...

Domestic violence, spouse abuse, and battering all refer to the victimization of a person with whom the abuser has or has had an intimate relationship. Domestic violence may take the form of physical, sexual and psychological abuse, is generally repeated, and often escalates within relationships. Most evidence indicates that domestic violence is predominantly perpetrated by men against women. Some evidence suggests that women are just as likely to use violence against male partners as men are...

While domestic violence is high on the public policy agenda in the UK, successive reviews have highlighted policing problems. A recent HMIC report found domestic violence is not policed at the same level as other offences and identified a catalogue of policing failures that have a long history of recurrence. With domestic violence accounting for around a large proportion of violent crime incidents reported to the police, and the majority of all female homicides (Office for National Statistics...

Economic growth, combustible renewables and waste consumption, and CO₂ emissions in North Africa.

This paper uses panel cointegration techniques and Granger causality tests to examine the dynamic causal link between per capita real gross domestic product (GDP), combustible renewables and waste (CRW) consumption, and CO2 emissions for a panel of five North African countries during the period 1971-2008. Granger causality test results suggest short- and long-run unidirectional causalities running from CO2 emissions and CRW consumption to real GDP and a short-run unidirectional causality running from CRW to CO2 emissions. The results from panel long-run fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS) estimates show that CO2 emissions and CRW consumption have a positive and statistically significant impact on GDP. Our policy recommendations are that these countries should use more CRW because this increases their output, reduces their energy dependency on fossil energy, and may decrease their CO2 emissions.

This paper discusses domestic energy use and energy behaviour. It shows some improvement in domestic energy consumption and adoption of good energy practice. The survey conducted indicated that 35% of homes could improve their energy efficiency by improved tank insulation. In the last 5 years condensing boilers have been installed only in 3% of homes, indicating that householders are unaware of their advantages. Although 88% of surveyed homes had purchased a major appliance in the last 2 years, only 16% had any idea of the energy rating of their new appliances. Use of energy saving light bulbs is predominant in kitchens compared to other rooms. 70–80% of householders undertook some kind of day-to-day energy efficiency measures. 20–35% of householders would like to invest in energy-saving measures but found cost to be a key barrier. Approximately 84% of those surveyed were unaware of the energy rating of their household appliances. Price and brand were the most important factors determining the purchase of a new appliance. Significant energy-saving could be achieved by providing appropriate information to the general public regarding temperature control, efficiency of appliances and energy-saving heating systems. - Highlights: ▶ Good practice in household energy use is being adopted but actual use is rising. ▶ Cost is dominant in energy related decisions purchasing of household appliances. ▶ Energy behaviour is improving but level of awareness needs more work.

Full Text Available Chlamydia spp. are obligate intracellular bacteria distributed all over the world, known to cause various forms of diseases in animals and humans. In the present study, a serological survey was conducted to detect the seroprevalence and risk factors associated with rabbit chlamydiosis in northeast China, including Liaoning province, Jilin province, Heilongjiang province, and Inner Mongolia Autonomous Region. Antibodies to Chlamydia were determined by indirect hemagglutination assay (IHA. The overall seroprevalence was estimated at 17.88% in total of 800 blood samples. The Chlamydia seroprevalence varied in domestic rabbits from different factors, and genders of domestic rabbits were considered as major risk factors associated with Chlamydia infection. Our study revealed a widespread and high prevalence of Chlamydia infection in domestic rabbits in northeast China, with higher exposure risk in female domestic rabbits. These findings suggested the potential importance of domestic rabbits in the transmission of zoonotic Chlamydia infection, and thus Chlamydia should be taken into consideration in diagnosing rabbit diseases. To our knowledge, there is no report of Chlamydia infection in domestic rabbits in China and the results extend the host range for Chlamydia, which has important implications for public health and the local economy.

Full Text Available The continuous dependence of man on fuel and service wood has resulted in serious degradation of the fragile forest ecosystem. Therefore, this study evaluated the sources and patterns of fuel wood and examined the rate of consumption in the study area. This was with the aim to assess the ecological implications of fuelwood consumption on species degradation. The study utilized both, primary and secondary data. Information was extracted from topographic map on the scale of 1: 50,000 and satellites imageries that cover the study area. Questionnaire administration, field observation and weight measurement of fuel wood were carried out. The results showed that the sources of fuel wood for domestic cooking were forest, nearby bush and abandoned farm while the sources of domestic energy were fuel wood (61.17%, charcoal (27%, kerosene (10%, electricity (1.33% and gas (0.5%. Fuel wood for small scale industries were: forest (49.23%, farmland (34.62 and fallow land (16.15%. The trend of fuel wood consumption was on the high side from 1995 to 2011, it was 58% in 1995, 70% in 2000, 82% in 2005 and 92% in 2010 and 2011 respectively. Many valuable economic tree species such as Triplochiton scleroxylon, Nesogordonia papaverifera, and Cordia spp. are near their extinction. Animals such as antelope, wolf and fox are going into extinction while monkey, grasscutter, hare, rabbit were endemic in the study area. The study concluded that the patterns of fuel wood use and fuel wood saturation presents a great danger for biodiversity products and services.

The Solomon Islands has one of the highest rates of domestic violence in the world. This paper is a descriptive case series of all cases of domestic violence presenting to the Solomon Islands National Referral Hospital (NRH) over 18 years. Data were routinely collected from a database of all patients who were treated by NRH general surgery and orthopedic clinicians between 1994 and 2011, inclusive. The total number of cases in the injury database as a result of domestic violence was 387. The average number of cases in the database per year from 1994 to 2011 was 20. There were 6% more female patients (205 of 387; 53%) than male (182 of 387; 47%). Of the cases in which the perpetrator of the violence against a female patient was specified (111 of 205 female cases), 74% (82 of 111) were the patient's husband. Only 5% (5 of 111) of cases in females were inflicted by another female. This analysis provides the best available information on domestic violence cases requiring a visit to a tertiary hospital in a Pacific Island in the specified time period and is undoubtedly an under-estimate of the total cases of domestic violence. Preventing and treating domestic violence in the Solomon Islands and in the Pacific is an important challenge and there is a significant role for secondary and tertiary health services in screening for and preventing domestic violence.

2012-11-01

Full Text Available Abstract Background A large number of people in both developing and developed countries rely on medicinal plant products to maintain their health or treat illnesses. Available evidence suggests that medicinal plant consumption will remain stable or increase in the short to medium term. Knowledge on what factors determine medicinal plant consumption is, however, scattered across many disciplines, impeding, for example, systematic consideration of plant-based traditional medicine in national health care systems. The aim of the paper is to develop a conceptual framework for understanding medicinal plant consumption dynamics. Consumption is employed in the economic sense: use of medicinal plants by consumers or in the production of other goods. Methods PubMed and Web of Knowledge (formerly Web of Science were searched using a set of medicinal plant key terms (folk/peasant/rural/traditional/ethno/indigenous/CAM/herbal/botanical/phytotherapy; each search terms was combined with terms related to medicinal plant consumption dynamics (medicinal plants/health care/preference/trade/treatment seeking behavior/domestication/sustainability/conservation/urban/migration/climate change/policy/production systems. To eliminate studies not directly focused on medicinal plant consumption, searches were limited by a number of terms (chemistry/clinical/in vitro/antibacterial/dose/molecular/trial/efficacy/antimicrobial/alkaloid/bioactive/inhibit/antibody/purification/antioxidant/DNA/rat/aqueous. A total of 1940 references were identified; manual screening for relevance reduced this to 645 relevant documents. As the conceptual framework emerged inductively, additional targeted literature searches were undertaken on specific factors and link, bringing the final number of references to 737. Results The paper first defines the four main groups of medicinal plant users (1. Hunter-gatherers, 2. Farmers and pastoralists, 3. Urban and peri-urban people, 4. Entrepreneurs and
