Ambient benzene measurements were conducted for the first time at four air monitoring sites in the Bangkok metropolitan region (BMR), from January to December 2001. Analytical results show that the mean benzene concentrations range from 42.4 μg/m 3 at the Din Daeng urban site to 15.1 μg/m 3 at the Chaeng Wattana suburban site. The monitoring results show that at a larger distance from the roadside or a higher level from the street surface, the level of benzene decreases. Analysis of the ambient benzene concentrations was carried out with reference to meteorological influences and traffic density. In traffic analysis, the combined effects of street topography and traffic flows established high impact on the overall benzene concentration in Bangkok. Statistical analysis shows good correlations of blood benzene levels and trans, trans-muconic acid with ambient benzene and demonstrated substantial exposure from traffic

Full Text Available This paper presents a new approach using an Artificial Neural Network technique to improve rainfall forecast performance. A real world case study was set up in Bangkok; 4 years of hourly data from 75 rain gauge stations in the area were used to develop the ANN model. The developed ANN model is being applied for real time rainfall forecasting and flood management in Bangkok, Thailand. Aimed at providing forecasts in a near real time schedule, different network types were tested with different kinds of input information. Preliminary tests showed that a generalized feedforward ANN model using hyperbolic tangent transfer function achieved the best generalization of rainfall. Especially, the use of a combination of meteorological parameters (relative humidity, air pressure, wet bulb temperature and cloudiness, the rainfall at the point of forecasting and rainfall at the surrounding stations, as an input data, advanced ANN model to apply with continuous data containing rainy and non-rainy period, allowed model to issue forecast at any moment. Additionally, forecasts by ANN model were compared to the convenient approach namely simple persistent method. Results show that ANN forecasts have superiority over the ones obtained by the persistent model. Rainfall forecasts for Bangkok from 1 to 3 h ahead were highly satisfactory. Sensitivity analysis indicated that the most important input parameter besides rainfall itself is the wet bulb temperature in forecasting rainfall.

Floodwater samples (N = 110) collected during the 2011 Bangkok floods were tested for Leptospira using culture and polymerase chain reaction (PCR); 65 samples were PCR-positive for putatively non-pathogenic Leptospira species, 1 sample contained a putatively pathogenic Leptospira, and 6 samples contained Leptospira clustering phylogenetically with the intermediate group. The low prevalence of pathogenic and intermediate Leptospira in floodwater was consistent with the low number of human leptospirosis cases reported to the Bureau of Epidemiology in Thailand. This study provides baseline information on environmental Leptospira in Bangkok together with a set of laboratory tests that could be readily deployed in the event of future flooding.

In recent years, the Thai government has strengthened drug law enforcement as a strategy to address a continuing epidemic of illicit drug use. We sought to assess temporal trends in street-level availability of illicit drugs among injection drug users (IDUs) in Bangkok, Thailand. Using univariate statistics and multivariate logistic regression, we assessed changes in the availability of five substances (heroin, methamphetamine, crystal methamphetamine, midazolam, and illicit methadone) between 2009 and 2011 and examined social, structural and individual factors influencing availability among community-recruited samples of IDUs in Bangkok. Availability was measured in three levels: immediate (available in ≤10 min); moderate (available in 10-90 min); and delayed (available in >90 min; our reference category). The analyses included 718 IDUs, including 165 (23.0%) women. Controlling for changes in participant characteristics between assessments, and in a period of constant nominal illicit drug prices, moderate availability of all substances increased significantly between 2009 and 2011, with adjusted odds ratios ranging between 2.36 (illicit methadone) and 4.61 (crystal methamphetamine) (all pdrug suppression efforts, the availability of illicit drugs among IDUs in Bangkok increased significantly between 2009 and 2011. The findings raise concern about the overreliance on drug law enforcement-based approaches and point to the need for greater investment in evidence-based drug policies.

The water budget of the Bangkok Metropolis system was analyzed using a material flow analysis model. Total imported flows into the system were 80,080 million m 3 per year (Mm 3 y -1 ) including inflows from the Chao Phraya and Mae Klong rivers and rainwater. Total exported flows out of the system were 78,528 Mm 3 y -1 including outflow into the lower Chao Phraya River and tap water (TW) distributed to suburbs. Total rates of stock exchange (1,552 Mm 3 y -1 ) were found in the processes of water recycling, TW distribution, domestic use, swine farming, aquaculture, and paddy fields. Only 21% of the total amount of wastewater (1,255 Mm 3 y -1 ) was collected, with insufficient treatment capacity of about 415 Mm 3 y -1 . Domestic and business (industrial and commercial sectors) areas were major point sources, whereas paddy fields were a major non-point source of wastewater. To manage Bangkok's water budget, critical measures have to be considered. Wastewater treatment capacity and efficiency of wastewater collection should be improved. On-site wastewater treatment plants for residential areas should be installed. Urban planning and land use zoning are suggested to control land use activities. Green technology should be supported to reduce wastewater from farming.

A rapidly increasing stray animal population in Bangkok has caused concern regarding transmission of vector-borne and zoonotic diseases. The purpose of this study was to determine if stray animals in Bangkok are a potential reservoir of Hepatozoon, a genus of tick-borne parasites that has received little attention in Thailand. Blood samples were collected from stray companion animals near monasteries in 42 Bangkok metropolitan districts. Both dogs and cats were sampled from 26 districts, dogs alone from 4 districts and cats alone from 12 districts. Samples were collected from a total of 308 dogs and 300 cats. Light microscopy and an 18 S rRNA gene-based PCR assay were used to test these samples for evidence of Hepatozoon infection. Gamonts were observed in blood smears for 2.6% of dogs and 0.7% of cats by microscopy. The PCR assay detected Hepatozoon in buffy coats from 11.4% of dogs and 32.3% of cats tested. The prevalence of infection was the same between male and female dogs or cats, and PCR-positive dogs and cats were found in 36.6% and 36.8% of the districts surveyed, respectively. There was an association between the percentages of PCR-positive dogs and cats in districts where both host species were sampled. Sequences of representative amplicons were closest to those reported for H. canis. These results represent the first molecular confirmation that H. canis is indigenous to Thailand. The unexpectedly high prevalence of Hepatozoon among stray cats indicates that their role in the epizootiology of hepatozoonosis should be investigated.

With an objective to save energies and reduce global warming gas emission, a feasibility study was performed on the oil burning thermal power plant in the city of North Bangkok in Thailand to reconstruct the plant into a natural gas burning combined cycle power plant. In the project, the old facilities with an output of 237.8 MW using three steam turbines in total will be reconstructed into a plant comprising of two steam turbines for 256,2 MW and two gas turbines for 460.4 MW, or a facility of 716.6 MW in total. The plant construction will have the gas turbines, steam turbines, generators, and a waste heat recovered steam generator fixed on one axis, two of which will be installed. The gas turbines will use natural gas as fuel, and the steam turbines will be operated by steam from the waste heat recovered steam generator. As a result of the discussions, the reduction of the energy consumption for a period of 40 years will correspond to crude oil of 20,560 kt, while the reduction of the global warming gas emission will be 107,200 t-CO2. In addition, the energy saving cost will be 9-ton crude oil equivalent/one million yen, and the cost for reduction of the global warming gas emission will be 47 t-CO2/one million yen. (NEDO)

Energy problems will play a fundamental role in the near future and researchers, engineers, economists and ecologists must work together to increase existing non-fossil energy sources and to develop new sources or techniques using less energy without pollution of the environment. Four aspects of future activities in this field are considered. First, energy sources, ie solar, fossil, nuclear, geothermal, and others such as wind energy or wave energy are considered in relation to the environment. Secondly the use of these sources by industry and by transportation, domestic, and agricultural sectors are examined. The problem of energy conservation in all fields is then considered. Finally the overall optimisation is analysed. This is the search for a compromise between the cost of usable energy and that of a degradation function taking into account the effect on the environment. (U.K.)

It is known that in-vehicle carbon dioxide (CO 2 ) concentration tends to increase due to occupant exhalation when the HVAC (heating, ventilation, and air conditioning) air is in recirculation mode. Field experiments were conducted to measure CO 2 concentration during typical commute in Bangkok, Thailand. The measured concentrations agreed with the concentration predicted using first-order mass balance equation, in both recirculating and outside air modes. The long-term transient decay of the concentration when the vehicle was parked and the HVAC system was turned off was also studied. This decay was found to follow Fickian diffusion process. The paper also provides useful operational details of the automotive HVAC system and fresh air ventilation exchange between cabin interior and exterior. Drivers in tropical Asian countries typically use HVAC recirculation mode in their automobiles. This behavior leads to excessive buildup of cabin CO 2 concentration levels. The paper describes the CO 2 buildup in a typical commute in Bangkok, Thailand. Auto manufacturers can potentially take measures to alleviate such high concentration levels. The paper also discusses the diffusion of CO 2 through the vehicle envelope, an area that has never been investigated before.

Full Text Available This study presents experimental results on Photovoltaic-thermal (PVT solar systems, the commercial photovoltaic (PV panels used as solar absorbers in PVT collectors, which are amorphous and multi-crystalline silicon. Testing was done with outdoor experiments in the climate of Bangkok corresponding to energy consumption behavior of medium size Thai families. The experimental results show that the thermal recovery of amorphous silicon PVT collector is almost the same as that of multi-crystalline silicon PVT collectors while electricity generation of multi crystalline silicon PVT is 1.2 times as much as that of amorphous silicon PVT. The maximum of heat gain from the PVT systems were obtained in March in summer. It was found that PVT collectors of unit area annually produced 1.1 × 10³ kWh/m² .year of heat and 55–83 kWh/m².year of electricity, respectively. The results show that annual average solar factor of hot water supply is 0.45 for unit collector area. Economical evaluation based on energy costs in Thailand was conducted, which estimated the payback time would be 7 and 14 years for a-Si PVT and mc-Si PV, respectively.

Only 3.4% of total water use in the Bangkok Metropolitan area is reused treated sewage. This study anticipates that further treated-sewage reuse in industrial sectors, commercial buildings and public parks, in addition to present in-plant and street cleaning purposes, would increase total water reuse to about 10%. New water reuse technologies using membrane bioreactor (MBR) and microfiltration (MF) as tertiary treatment were implemented to assess their potential for their application in the Bangkok Metropolitan area. The MBR was applied to the treatment of raw sewage in a central treatment plant of the Bangkok Metropolitan area. The MF membrane was used for polishing the effluent of the treatment plant. The results show the quality of treated water from MBR and tertiary MF treatment could meet stringent water reuse quality standard in terms of biochemical oxygen demand, suspended solids and biological parameters. Constant permeate flux of the membrane was achieved over long-term operation, during which inorganic fouling was observed. This is due to the fact that incoming sewage contains a considerable amount of inorganic constituents contributed from storm water and street inlet in the combined sewerage systems. The total cost of the MBR for sewage treatment and production of reuse water is estimated to be about USD1.10/m3.

Numerical Simulation for a Three-Dimensional Air Pollution Measurement Model in a Heavy Traffic Area under the Bangkok Sky Train Platform

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available Air pollutant levels in Bangkok are generally high in street tunnels. They are particularly elevated in almost closed street tunnels such as an area under the Bangkok sky train platform with high traffic volume where dispersion is limited. There are no air quality measurement stations in the vicinity, while the human population is high. In this research, the numerical simulation is used to measure the air pollutant levels. The three-dimensional air pollution measurement model in a heavy traffic area under the Bangkok sky train platform is proposed. The finite difference techniques are employed to approximate the modelled solutions. The vehicle air pollutant emission due to the high traffic volume is mathematically assumed by the pollutant sources term. The simulation is also considered in averaged and moving pollutant sources due to manner vehicle emission. The proposed approximated air pollutant concentration indicators can be replaced by user required gaseous pollutants indices such as NOx, SO2, CO, and PM2.5.

Measurement of Volatile Organic Compound (VOC) was carried out in suburban Bangkok during July 2-8, 2008. Analysis was performed using GC-FID and GC-MS. High mixing ratios of VOCs detected during the morning and evening are most likely due to vehicular emissions. Averaged VOC mixing ratios revealed distinct difference between mixing ratios of weekdays and weekend, which the latter were found to be lower. The most abundance species were propane and toluene. Ratios of benzene over toluene suggested that additional toluene mixing ratios was owing to industrial emission, which was particularly larger during weekdays. Comparison between C2Cl4 and CH3Cl mixing ratios obtained for suburban Tokyo reveal a relatively lower influence of biomass burning than suburban Bangkok. Elucidating by Ozone Formation Potential, toluene was found to contribute the most to O3 production followed by ethylene, m-,p-xylene, and propylene.

This study explored the association between mothers' work-related factors and breastfeeding practices in Bangkok, Thailand. Data were collected from 84 working mothers with a child aged 6 to 24 months who visited the breastfeeding mobile clinic at a nursery goods exhibition. Thai interviewers collected data using a structured questionnaire. Analysis of the data showed that exclusive breastfeeding for 3 months was 78.6%, and for 6 months it was 38.1%. Mothers who returned to work 3 months or more after giving birth exclusively breastfed more than the mothers who returned to work in less than 3 months (crude odds ratio [OR] = 4.26, 95% confidence interval [CI] = 1.39-13.05; adjusted OR = 4.15, 95% CI = 1.15-14.95). Moreover, mothers who worked at self-employed or family-owned businesses and some mothers working at private companies showed tendencies of returning to work in less than 3 months. Results suggest that longer maternity leave would help extend the duration of exclusive breastfeeding. In addition, the improvement of a breastfeeding supportive environment in the workplace would be valuable and may be an effective means to improve breastfeeding practices and infant health. © 2011 APJPH.

To explore the effects of HbJ Bangkok, HbE, HbG Taipei, and α-thalassemia HbH on the results of HbA1c assessment using ion-exchange high-performance liquid chromatography (IE-HPLC). We enrolled five patients in which the results of the IE-HPLC HbA1c assay were inconsistent with the average levels of FBG. We performed hemoglobin capillary (Hb) electrophoresis using whole-blood samples. We also sequenced the genes encoding Hb using dideoxy-mediated chain termination and analyzed HbA1c using borate affinity HPLC (BA-HPLC) and turbidimetric inhibition immunoassay (TINIA). Two patients had the HbJ Bangkok variant. Hb genotypes of these patients were β 41-42 /β J Bangkok and β N /β J Bangkok , and the content of HbJ Bangkok was 93.9% and 52.4%, respectively. The remaining three patients had the following: HbE (β N /β E Hb genotype, 23.6% HbE content), HbG Taipei (β N /β G Taipei Hb genotype, 39.4% HbG Taipei content), and α-thalassemia HbH (6.1% HbH content, 2.8% Hb Bart's content). In the patients with β-thalassemia and HbJ Bangkok variants, the presence of the variants interfered with the results of HbA1c analyses using IE-HPLC and TINIA; in the remaining four patients, there was interference with the results of HbA1c IE-HPLC but not with the TINIA assay. There was no interference with BA-HPLC HbA1c results. HbJ Bangkok, HbE, HbG Taipei Hb, and α-thalassemia HbH disease cause varying degrees of interference with the analysis of HbA1c using IE-HPLC. In these patients, we suggest using methods free from such interference for the analysis of HbA1c and other indicators to monitor blood glucose levels. © 2017 Wiley Periodicals, Inc.

Sun protection behavior is a proven intervention for aging skin and skin cancer prevention, especially if training on prolonged sun exposure can be performed early in life. Despite the fact that there are several study reports from multicenters in the West, there are limited data on sun protection in tropical countries where the prevalence of sunburn as well as sun protection behavior and knowledge are low. In Bangkok, sun protection behavior among adolescents is different from the studies performed in the West. Schools are key institutions in encouraging students to prevent themselves from acquiring problems of long-time sun exposure. To assess the amount of time exposed to the sun, sun protection behavior, attitudes, and knowledge about sun exposure protection among secondary school adolescents in Bangkok, Thailand. This is a nonrandomized, cross-sectional survey. All students from seven secondary schools in Bangkok (public/private, male/female/coed) were recruited in to the study. A total of 10,387 students were enrolled in to the study; 6176 (59.5%) and 4211 (40.5%) students were from grades 7 to 9 and 10 to 12, respectively. Male students significantly lacked proper sun-protecting behaviors when compared to the female students in the use of sunscreen (9.4% vs. 28.0%, P protecting behaviors among junior high school students were deficient when compared to high school students in the use of sunscreen (57.1% vs. 60.6%, P protection behavior among adolescents in Bangkok was poor compared to Western countries. The attitudes and general knowledge about sun protection were significantly different among male and female students from grades 7 to 9 and 10 to 12. The limitation of the study is the use of self-reported questionnaires in assessing sun exposure and protection. © 2012 John Wiley & Sons A/S.

Background Thailand’s long-standing HIV sero-sentinel surveillance system for people who inject drugs (PWID) is confined to those in methadone-based drug treatment clinics and representative data are scarce, especially outside of Bangkok. Methods We conducted probability-based respondent-driven sampling (RDS) surveys in Bangkok (n = 738) and Chiang Mai (n = 309) to increase understanding of local HIV epidemics and to better inform the planning of evidence-based interventions. Results PWID had different epidemiological profiles in these two cities. Overall HIV prevalence was higher in Bangkok (23.6% vs. 10.9%, p Chiang Mai, HIV infections appear to be more recently acquired and PWID were younger and had higher levels of recent injecting and sexual risk behaviors with lower levels of intervention exposure. Methamphetamine was the predominant drug injected in both sites and polydrug use was common although levels and patterns of the specific drugs injected varied significantly between the sites. In multivariate analysis, recent midazolam injection was significantly associated with HIV infection in Chiang Mai (adjusted odds ratio = 8.1; 95% confidence interval: 1.2–54.5) whereas in Bangkok HIV status was not associated with recent risk behaviors as infections had likely been acquired in the past. Conclusion PWID epidemics in Thailand are heterogeneous and driven by local factors. There is a need to customize intervention strategies for PWID in different settings and to integrate population-based survey methods such as RDS into routine surveillance to monitor the national response.

Overall HIV prevalence was higher in Bangkok (23.6% vs. 10.9%, pChiang Mai, HIV infections appear to be more recently acquired and PWID were younger and had higher levels of recent injecting and sexual risk behaviors with lower levels of intervention exposure. Methamphetamine was the predominant drug injected in both sites and polydrug use was common although levels and patterns of the specific drugs injected varied significantly between the sites. In multivariate analysis, recent midazolam injection was significantly associated with HIV infection in Chiang Mai (adjusted odds ratio=8.1; 95% confidence interval: 1.2-54.5) whereas in Bangkok HIV status was not associated with recent risk behaviors as infections had likely been acquired in the past. PWID epidemics in Thailand are heterogeneous and driven by local factors. There is a need to customize intervention strategies for PWID in different settings and to integrate population-based survey methods such as RDS into routine surveillance to monitor the national response.

Full Text Available The Scedosporium apiospermum species complex is an emerging filamentous fungi that has been isolated from environment. It can cause a wide range of infections in both immunocompetent and immunocompromised individuals. We aimed to study the genetic variation and relationships between 48 strains of S. apiospermum sensu stricto isolated from soil in Bangkok, Thailand. For PCR, sequencing and phylogenetic analysis, we used the following genes: actin; calmodulin exons 3 and 4; the second largest subunit of the RNA polymerase II; ß-tubulin exon 2-4; manganese superoxide dismutase; internal transcribed spacer; transcription elongation factor 1α; and beta-tubulin exons 5 and 6. The present study is the first phylogenetic analysis of relationships among S. apiospermum sensu stricto in Thailand and South-east Asia. This result provides useful information for future epidemiological study and may be correlated to clinical manifestation.

Full Text Available Hanging is violent asphyxial death. The objective of this study is to assess the data of hanging cases. A descriptive-retrospective study was conducted. We studied 244 hanging cases autopsied in Forensic Division, Department of Pathology, Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok, Thailand, between January 2001 and December 2013. The study included 197 men (80.7% and 47 women (19.2%. Their age ranged from 14 to 93 years. Most of these cases were incomplete hanging (83.6%. Features of hanging victims, such as tongue protrusion; congestion of face; petechial hemorrhage of face, conjunctiva, and internal organs; and neck injuries, significantly correlated with complete hanging. The predominant occupation of hanging victims was in the service industry (63.1%. Suicides usually occurred in private homes or apartments (84.8%. A suicide note was found in 6.1% of cases. The most common ligature material used was nylon rope, found in 61.1% of cases. The most underlying diseases of the victims in hanging cases were tuberculosis and human immunodeficiency virus infection, 9 cases each. Blood ethanol levels of 29 cases (11.8% were detected to be higher than 150 mg%. Methamphetamine and benzodiazepine were detected in 5.3% and 3.3% of cases, respectively. This study provides comprehensive baseline data of hanging cases in central Bangkok.

Full Text Available Despite Thailand's commitment to treating people who use drugs as "patients" not "criminals," Thai authorities continue to emphasize criminal law enforcement for drug control. In 2003, Thailand's drug war received international criticism due to extensive human rights violations. However, few studies have since investigated the impact of policing on drug-using populations. Therefore, we sought to examine experiences with policing among people who inject drugs (PWID in Bangkok, Thailand, between 2008 and 2012.Between July 2011 and June 2012, semi-structured, in-depth interviews were conducted with 42 community-recruited PWID participating in the Mitsampan Community Research Project in Bangkok. Interviews explored PWID's encounters with police during the past three years. Audio-recorded interviews were transcribed verbatim, and a thematic analysis was conducted to document the character of PWID's experiences with police. Respondents indicated that policing activities had noticeably intensified since rapid urine toxicology screening became available to police. Respondents reported various forms of police misconduct, including false accusations, coercion of confessions, excessive use of force, and extortion of money. However, respondents were reluctant to report misconduct to the authorities in the face of social and structural barriers to seeking justice. Respondents' strategies to avoid police impeded access to health care and facilitated transitions towards the misuse of prescribed pharmaceuticals. The study's limitations relate to the transferability of the findings, including the potential biases associated with the small convenience sample.This study suggests that policing in Bangkok has involved injustices, human rights abuses, and corruption, and policing practices in this setting appeared to have increased PWID's vulnerability to poor health through various pathways. Novel to this study are findings pertaining to the use of urine drug

Air pollution data in Bangkok, Thailand, indicate that levels of particulate matter with aerodynamic diameter air pollution in Bangkok, Thailand. The study period extended from 1999 to 2003, for which the Ministry of Public Health provided the mortality data. Measures of air pollution were derived from air monitoring stations, and information on temperature and relative humidity was obtained from the weather station in central Bangkok. The statistical analysis followed the common protocol for the multicity PAPA (Public Health and Air Pollution Project in Asia) project in using a natural cubic spline model with smooths of time and weather. The excess risk for non-accidental mortality was 1.3% [95% confidence interval (CI), 0.8-1.7] per 10 microg/m(3) of PM(10), with higher excess risks for cardiovascular and above age 65 mortality of 1.9% (95% CI, 0.8-3.0) and 1.5% (95% CI, 0.9-2.1), respectively. In addition, the effects from PM(10) appear to be consistent in multipollutant models. The results suggest strong associations between several different mortality outcomes and PM(10). In many cases, the effect estimates were higher than those typically reported in Western industrialized nations.

Over half the world's 7.2 billion population are living in urban habitats. While these cities only occupy 2% of the world's surface, the ecological footprint by these cities combined is far greater than that of the other 98% of the world. Bangkok, Thailand has experienced this rapid urbanization that has resulted in various environmental problems, including pollution, land subsidence, and flooding. Major flooding in 2011 has raised awareness about the importance of restoring ecosystem services in urban space to cope up with the forecasted extreme climatic conditions. Finding localized flooding, carbon and pollution mitigation methods will be important to cities. Upland reforestration has been proposed as a way to decrease these anthropogenic and climate change impacts. However, there is also a large area of wetlands in Bangkok with possibly high ecosystem services that have not been quantified. This study measure above ground and below ground carbon accumulation in wide-spread Typha angustifolia wetlands as an untapped source of ecosystem services that are worth projected. These wetlands are typically viewed as wasteland and are not being protected. We examined carbon and heavy metals (Pb, Zn, Cu) pools in 7 wetlands across Bangkok with various environmental settings--from industrialized zone, to residential area, farms, and protected urban green space. The results indicate recent peat accumulation layer by these wetlands at high rate. Heavy concentration are found near contaminant source such as industries and farms. Combined with their ability to buffer storms and being habitats for wildlife, these wetlands have important values in increasing ecosystem services in urban space and should be considered for protection.

Travelers' diarrhea (TD) is the most prevalent disorder affecting travelers to developing countries. Thailand is considered "moderately risky" for TD acquisition, but the risk by city visited or behavior of the visitor has yet to be definitely defined. Restaurant eating is consistently associated with the acquisition of diarrhea while traveling, and pathogen-free meals serve as a marker of public health success. This study seeks to ascertain a traveler's risk of exposure to certain bacterial gastric pathogens while eating at Bangkok restaurants recommended in popular tourist guide books. A cross-sectional tourist restaurant survey was conducted. Thirty-five restaurants recommended in the two top selling Bangkok guidebooks on Amazon.com were sampled for bacterial pathogens known to cause diarrhea in Thailand, namely Salmonella, Campylobacter, and Arcobacter (a Campylobacter-like organism). A total of 70 samples from two meals at each restaurant were obtained. Suspected bacterial pathogens were isolated by differential culture and tested for antibiotic resistance. Salmonella group E was isolated from one meal (2%), and Arcobacter butzleri from nine meals (13%). Campylobacter spp. were not found. The large majority of A butzleri isolates were resistant to azithromycin but susceptible to ciprofloxacin and an aminoglycoside. A traveler's risk of exposure to established bacterial pathogens, Salmonella and Campylobacter, by eating in recommended restaurants is small. Arcobacter butzleri exposure risk is 13% per meal eaten, and rises to 75% when 10 meals are eaten. All restaurants, regardless of price, appear to be equally "risky." Current evidence points to Arcobacter being pathogenic in humans; however, further research is needed to conclusively define pathogenicity. Routine prophylaxis for diarrhea is not recommended; however, travelers should be aware of the risk and come prepared with adequate and appropriate self-treatment medications.

The double heterozygosity for α and β chain variants leads to the formation of abnormal heterodimer hybrids, which could render laboratory diagnostics in a routine setting difficult. The following is the first report of a double heterozygosity for Hb Q-Thailand [α74(EF3)Asp→His; HBA1: c.223G>C] with α + -thalassemia (α + -thal) and Hb J-Bangkok [β56(D7)Gly→Asp; HBB: c.170G>A] found in a Chinese family. Both subjects were healthy with normal or borderline hematological parameters. Hemoglobin (Hb) analyses showed a novel variant, Hb Q-Thailand and Hb J-Bangkok. Family studies helped in the initial recognition and in making presumptive diagnoses, but definitive diagnoses of these cases with complex α and β chain variants could only be obtained after DNA analysis.

This study used respondent-driven sampling to explore the effects of social support on HIV risk and protective factors among young males who have sex with males (YMSM) in Bangkok (N = 273) and Chiang Mai (N = 243), Thailand. It compared different measures of social support, including living situation, the proportion of family and friends to whom the respondent had disclosed their same-sex attraction, and scores on the multi-dimensional scale of perceived social support as predictors of two outcomes of interest-coerced first sex and HIV knowledge. Social support from family played a mediating role in both outcomes among YMSM in Bangkok but not those from Chiang Mai. Though social support from friends was also studied, it was less strongly associated with the outcomes of interest. The findings support interventions designed to leverage social support networks to increase HIV knowledge and decrease coerced first sex among YMSM. At the same time, they demonstrate that there is not a single risk or demographic profile encompassing all YMSM. Successful programs and policies will need to consider the specific attributes and social environment of YMSM in particular locations in order to effectively address HIV risks.

Thailand has relied on drug law enforcement in an effort to curb illicit drug use. While anecdotal reports suggest that Thai police frequently use urine toxicology to identify drug users, little is known about the prevalence or impacts of this practice among people who inject drugs (IDU). Therefore, we sought to examine experiences with urine drug testing by police among IDU in Bangkok. Data were derived from a community-recruited sample of IDU in Bangkok participating in the Mitsampan Community Research Project between July and October 2011. We assessed the prevalence and correlates of being subjected to urine toxicology testing by police using multivariate Poisson regression. In total, 438 IDU participated in this study, with 293 (66.9%) participants reporting having been tested for illicit drugs by police. In multivariate analyses, reports of drug testing by police were independently and positively associated with younger age (adjusted prevalence ratio [APR]: 1.28), a history of methamphetamine injection (APR: 1.22), a history of incarceration (APR: 1.21), having been in compulsory drug detention (APR: 1.43), avoiding healthcare (APR: 1.15), and HIV seropositivity (APR: 1.19), and negatively associated with access to voluntary drug treatment (APR: 0.82) (all p<0.05). A high proportion of IDU in Bangkok were subjected to drug testing by police. Young people and methamphetamine injectors were more likely to have been tested. The findings indicate that drug testing by police is associated with the compulsory drug detention system and may be interfering with IDU's access to healthcare and voluntary drug treatment. These findings raise concern about the widespread practice of drug testing by police and its associated impacts. Copyright © 2013 Elsevier B.V. All rights reserved.

Energy is one of the most important prerequisites of life. The growing socio-economic activities and the rising standard of living have led to a rapid increase in energy consumption. The limited resources of fossil fuels and the recent geopolitical developments activated the exploration of ways and means for energy conservation and exploitation of unconventional renewable sources of energy. Of the renewable energy sources (geothermal, solar, tidal, hydropower, etc), hydro-power production has some potential environmental effects. Man-made lakes have several physical, biological, geochemical and biogeochemical impacts on the environment both in the area of the lake and downstream. From the socio-economic point of view, the harnessing of renewable sources of energy will not only lead to the enhancement of the human environment, particularly in remote rural areas in developing countries, but will also lead to substantial savings in the use of non-renewable sources of energy.

This study aimed to assess the effectiveness of Participatory Learning School and Family Based Intervention Program for Preventing Game Addiction by Developing Self-Regulation of gaming addiction among students of grades 4 and 5 in Bangkok. A quasi-experimental study was implemented among students of grades 4 and 5 at primary schools in Bangkok selected through multistage random sampling. Two comparable schools were randomly assigned to either the intervention or control group. Then, 310 students in the randomly selected classrooms were allocated to each group. The intervention group received the self-regulation program with school and family involvement to prevent gaming addiction. Master teachers attended in-house training on prevention of gaming addiction in children. Parents of these children received a gaming addiction prevention manual and guidelines. The program lasted 8 weeks. The control group received no intervention. Knowledge and Attitude About Gaming Questionnaire, Game Addiction Screening Test (GAST), and Game Addiction Protection Scale were utilized to assess subjects at baseline, immediately after, and 3 months post-intervention. Descriptive statistics, chi-square, and independent t -test were used to describe characteristics of the participants, and repeated measures ANOVA was analyzed to test the effectiveness of the intervention. The findings revealed that there were significant differences in knowledge, attitude, self-regulation, and gaming addiction behaviors ( p gaming addiction in students of grades 4 and 5 in Bangkok, Thailand.

The present study was cross-sectional survey aiming to describe oral health status in terms of caries and periodontal experience and oral health behavior of 998 priests in Bangkok. The 998 priests, aged 12-92, from 28 temples in Bangkok were clinically examined at Priest Hospital using WHO methodology. Information on oral health behavior was obtained via questionnaires. The prevalence and level of caries increased with ages. Overall, 89.5% had evidences of caries experience; 71.5% were related to untreated caries. The average DMFT score was 7.4 (DT=2.9, MT=3.2, FT= 1.2). About 72.9% needed 1-surface filling and 45.6% needed extraction. Similarly, gingivitis was highly prevalent for all age groups, with 73.4% having calculus. About 12.7% had periodontal pockets. However, the highest prevalence of periodontitis belonged to the 55-64-year-old priest at 41.4%. Tooth loss was dramatically prevalent among the elderly over 65. Even though most participatting priests had high evidences of caries and periodontal problems, only 57.7% perceived their own problems. The first and second common problems were calculus and food retention, at 48.9 and 44.1, respectively.

The energy-development-environment nexus

Schneider, Bertrand

Energy is the key factor in tackling two of the major problems now facing humanity: the environment and development. Adequate and appropriate energy supplies are essential to economic and social development, especially for Third World countries, but at the same time energy production and utilization are responsible for much of the damage being done to the environment. As everyone now knows, the combustion of fossil fuels is the main source of greenhouse gases and of the threat to the stability of world climate. Nuclear power, which once seemed an answer to the constantly increasing demand for energy, is now challenged by public opinion in many countries as a result of various nuclear accidents and the problems of processing and storing nuclear waste. So how do we extricate ourselves from the energy environment-development tangle? Clearly, advanced countries have an interest in transferring environment-friendly technologies to developing countries in order to reduce the pollution which puts the global as well as the local environment at risk. The North is, by and large, becoming aware of the choices involved in protecting the environment versus industrial growth and unlimited use of motor vehicles. For the South, these choices are a luxury they can ill afford, given the imperative of rapid development. The solution must be for greater international co-operation, with the North assisting the South (and the former Communist bloc) financially and through transfer of appropriate technologies at affordable cost. Reconciling the environment and development with respect to the energy cycle is a task of fundamental importance for the future. The prime responsibility for this task obviously lies with industries, but action is also required from governments, to enable them to play their part effectively. Advanced countries must demonstrate that development is fully compatible with protecting the environment. They can do so by using market forces, provided that the appropriate

With an objective of saving energy and reducing greenhouse gas emission, a modernization project has been discussed on the North Bangkok heavy oil burning thermal power plant owned by Electricity Generating Authority of Thailand (EGAT). The present project plans to withdraw the existing units No. 1, 2 and 3, and install two new generating facilities with the rated output of 358.3 MW using natural gas as fuel. The present feasibility survey has performed detailed comparative discussions on four cases, whereas a proposal was selected to withdraw all of the boilers, steam turbines, and generators, and install two single axis combined cycle systems whose output has been increased by using the existing fuel tank area. The energy saving effect by this project can reduce fuel consumption annually by 514 kt of crude oil equivalent. The greenhouse gas can be reduced annually by 2,680 kt-CO2. The project will require a total fund of about 57 billion yen. The profitability assessment calls for the internal profitability of 8.413% and the investment fund efficiency of 1.69%. The economic investment payback effect of this project is determined sufficient. (NEDO)

Elucidation of air quality in the suburban area of Bangkok, Thailand is essential in order to achieve effective regulations and mitigation strategies. VOCs plays important role in formation of tropospheric urban ozone. Without overkill NO concentration, transport of O3 precursors into suburban area which add surplus to local O3 formation as well as direct transport of O3 itself results in relatively higher total O3 observed in suburban area rather than urban. Whole air canister sampling was carried out in the suburban Bangkok during 2008, July 2-7. 4 samples per day were collected at 30 min passes 6, 12, 17, 21 hours with sampling time of 1 min. Analysis was achieved by using GC-FID and GC-MS. High concentrations of VOCs detected during the peak periods in the morning and evening are most likely due to vehicular emission. Averaged VOCs concentrations, reveal distinct different between data measured for weekday and weekend which the latter were found with lower concentrations. No difference was found for CFCs which the levels are also comparable to global background level reported by World Meteorological Organization. The most abundance species have found to be propane and toluene with averaged concentration of 3100 and 2891 pptv, respectively. Ratios of benzene over toluene suggest additional concentration owing to industrial emission, of which particularly larger during the weekday. Comparison with C2Cl4 and CH3Cl concentrations obtained for suburban Tokyo reveal relatively higher influence of biomass burning at suburban Bangkok. In order to estimate the role of the different VOCs towards tropospheric ozone formation, ozone formation potential was calculated using maximum incremental reactivity. Toluene was found to contribute the most to O3 production followed by ethylene, m,p-xylene, and propylene.

HIV infection among men who have sex with men, particularly in Thai urban settings and among younger cohorts, is escalating. HIV testing and counseling (HTC) are important for prevention and obtaining treatment and care. We examine data from a 2013 survey of males, 15-24 years, reporting past-year sex with a male and living in Bangkok or Chiang Mai. Almost three quarters of young MSM (YMSM) in Bangkok and only 27 % in Chiang Mai had an HIV test in the previous year. Associations for HIV testing varied between cities, although having employment increased the odds of HIV testing for both cities. In Bangkok, family knowledge of same sex attraction and talking to parents/guardians about HIV/AIDS had higher odds of HIV testing. Expanded HTC coverage is needed for YMSM in Chiang Mai. All health centers providing HTC, including those targeting MSM, need to address the specific needs of younger cohorts.

The effects of air pollution on human health are a great concern, particularly in big cities with severe traffic problems such as Bangkok, Thailand. In this study, exposure to genotoxic compounds in ambient air was studied by analysis of particle-associated polycyclic aromatic hydrocarbons (PAHs) and benzene through direct measurement of concentrations in air as well as through the use of different biomarkers of exposure: urinary 1-hydroxypyrene (1-OHP) for PAHs and urinary t,t-muconic acid (t,t-MA) for benzene. The study was conducted in various susceptible groups of the population with different occupations in 5 traffic-congested areas of Bangkok, as well as in primary school children. The level of total PAHs on the main roads at various sites ranged from 7.10 to 83.04 ng/m 3 , while benzene levels ranged from 16.35 to 49.25 ppb. In contrast, ambient levels in nearby temples, the control sites, ranged from 1.67 to 3.04 ng/m 3 total PAHs and 10.16 to 16.25 ppb benzene. Street vendors selling clothes were exposed to 16.07 ± 1.64 ng/m 3 total PAHs and 21.97 ± 1.50 ppb benzene, levels higher than in monks and nuns residing in nearby temples (5.34 ± 0.65 ng/m 3 total PAHs and 13.69 ± 0.77 ppb benzene). Grilled-meat vendors in the same area were exposed to both total PAHs and benzene at even higher levels, possibly due to additional formation of PAHs during the grilling of meat (34.27 ± 7.02 ng/m 3 total PAHs; 27.49 ± 2.72 ppb benzene). At the end of the workday, urinary 1-OHP levels in street vendors (0.12 and 0.15 μmol/mol creatinine in clothes and grilled-meat vendors, respectively) were significantly higher than in controls (0.04 μmol/mol creatinine; P 3 and 4.71 ± 0.25 ppb, respectively, higher than those to which children living outside the city were exposed (1.25 ± 0.24 ng/m 3 total PAHs; 2.10 ± 0.16 ppb benzene). At the end of the school day, levels of urinary 1-OHP and t,t-MA were significantly higher (P < 0.001 and P < 0.01, respectively) in

The current unsustainable practices worldwide in energy production and consumption have led to a plethora of environmental problems. Until recently environmental law largely overlooked the relevance of energy production and consumption; energy was seen to be of little significance to the advancement of sustainable development. This has changed since 2000 with the global concern attached to climate change, the publication by the United Nations of the World Energy Assessment and the detailed consideration given to this issue at the World Summit on Sustainable Development in Johannesburg in 2002. Australia has been seen to be lagging behind the other major industrialised nations of the world in addressing sustainable energy issues. Contents are: Overview of energy production and use in Australia; 2. Energy technologies and sustainable development; 3. Energy, international environmental law and sustainable development; 4. Evaluating Australian government initiatives relating to energy, climate change and the environment; 5. Sustainable energy in the Australian electricity and gas sectors; 6.

To examine relationships between location, demographics, lifestyle, beliefs, and experience of hot flushes and night sweats (HFNS) amongst women living in two cities in Thailand. Cross-sectional study of peri- and postmenopausal women, aged 45-55 years, from Bangkok and Chiang Mai. Participants completed questionnaires (demographics, health, HFNS (prevalence, frequency and problem-rating) and beliefs about menopause). A sub-sample of women from each location was interviewed. A total of 632 women (320 Bangkok and 312 Chiang Mai) aged 50.88 (standard deviation 3.06) years, took part. The prevalence of HFNS was 65%, average HFNS frequency 8.7 (10.8) per week and problem rating 4.3/10. Women from Chiang Mai had significantly more problematic HFNS, but prevalence and frequency were similar in both sites. Poor general health predicted HFNS prevalence and frequency, while Chiang Mai location, HFNS frequency, age, diet and beliefs about menopause were associated with problematic HFNS. Location remained significant after controlling for education, occupation and age; location was partially explained by beliefs. Qualitative interview responses illustrated the differences in beliefs about menopause between locations. HFNS reports are prevalent with moderate frequency and problem-ratings in these urban centers in Thailand. The results will be included in the broader International Menopause Society study of Climate, Altitude and Temperature (IMS-CAT) of the impact of climate on HFNS.

Based upon the more meaningful changing recorded within the Italian energy sector in the year 2000, the Studies Department of ENEA (the Italian National board for new technologies, energy and environment) prepared the 'Rapporto Energia e Ambiente 2000', which provides a picture of the country energy and energy-related activities concerning the environment. In this paper, it is only provided a summary of the whole work. The complete report can be downloaded from the ENEA main page (www.enea.it). Italy gross domestic product (Gdp) grew by almost 3% in the year 2000, mostly sustained by an increase in the industrial production and services, as well. At the same time the total energy consumption rose to almost 185 Mtoe (+1% over 1999). Because Gdp grew more than the energy consumption, the energy intensity decreases in the year 2000. Almost 82% of the Italian energy needs (mainly oil and gas, even if electricity imports are increasing) depend upon imports. This heavy burden makes Italy particularly sensitive to both the oil price fluctuations and the euro/dollar exchange rate. Transportation absorbs a large and growing share of the energy consumption while showing quite an impact on the environment. From the supply side, renewable energy sources appear very promising because they allow the use of local resources, promote local development and may create new jobs, in area of the country with less favourable economic conditions. First among the European countries, a market mechanism to increase the use of renewable by establishing that a share of the whole electricity production (currently set at 2%) has to come from renewable has been introduced. However among the OECD countries, Italy records the lowest rate of R/D investments to GDP. This rate should more than double if the new opportunities coming from the development of innovative energy technologies have to be fully exploited [it

Energy-water-environment nexus is very important to attain COP21 goal, maintaining environment temperature increase below 2°C, but unfortunately two third share of CO2 emission has already been used and the remaining will be exhausted by 2050. A number of technological developments in power and desalination sectors improved their efficiencies to save energy and carbon emission but still they are operating at 35% and 10% of their thermodynamic limits. Research in desalination processes contributing to fuel World population for their improved living standard and to reduce specific energy consumption and to protect environment. Recently developed highly efficient nature-inspired membranes (aquaporin & graphene) and trend in thermally driven cycle\\'s hybridization could potentially lower then energy requirement for water purification. This paper presents a state of art review on energy, water and environment interconnection and future energy efficient desalination possibilities to save energy and protect environment.

Exploitation of energy has some impact on the environment. Six essays are presented to examine the variety of problems: (1) Sir Samuel Curran, in Energy and the Needs of Man, concludes that techniques to produce new energy sources will be found, bur conservation and the population explosion must be seriously examined; (2) Dr. Earl Cook, in Flow of Energy Through Technological Society, shows where energy comes from, how it is used and how it returns to the environment; he emphasizes the inefficiency of many energy conversion processes in consequence of the Second law of Thermodynamics; (3) Dr. Andrew Parteous, in Economical Use of Energy and Materials, explains energy not only used in heating, lighting, and transport, but in industry; his accounting of energy shows waste, and he stresses recycling and recovering the energy in domestic waste; (4) Sir Frank McFadzean, in Energy--the International Scene, examines the interplay of economics, technology, and politics in the oil industry; he suggests that more mature international leadership is needed to overcome the current difficulties facing producers and consumers; (5) J. D. Dunster, in The Atom and the Environment, examines the environmental impact of nuclear energy where the safety standards are more strenuous, but are feared more; he is a proponent of nuclear energy, but says an overall energy policy, balancing environmental factors against economic and political considerations, is needed; Dr. B. J. Brinkworth, in Direct Use of Solar Energy, reminds us that the Sun is the ultimate source of energy, and says solar energy can be exploited globally without damaging the environment. (MCW)

Natthanej Luplertlop

Full Text Available The Scedosporium apiospermum species complex, comprising filamentous fungal species S. apiospermum sensu stricto, S. boydii, S. aurantiacum, S. dehoogii and S. minutispora, are important pathogens that cause a wide variety of infections. Although some species (S. boydii and S. apiospermum have been isolated from patients in Thailand, no environmental surveys of these fungi have been performed in Thailand or surrounding countries. In this study, we isolated and identified species of these fungi from 68 soil and 16 water samples randomly collected from 10 parks in Bangkok. After filtration and subsequent inoculation of samples on Scedo-Select III medium, colony morphological examinations and microscopic observations were performed. Scedosporium species were isolated from soil in 8 of the 10 parks, but were only detected in one water sample. Colony morphologies of isolates from 41 of 68 soil samples (60.29% and 1 of 15 water samples (6.67% were consistent with that of the S. apiospermum species complex. Each morphological type was selected for species identification based on DNA sequencing and phylogenetic analysis of the β-tubulin gene. Three species of the S. apiospermum species complex were identified: S. apiospermum (71 isolates, S. aurantiacum (6 isolates and S. dehoogii (5 isolates. In addition, 16 sequences could not be assigned to an exact Scedosporium species. According to our environmental survey, the S. apiospermum species complex is widespread in soil in Bangkok, Thailand.

The Royal Australian Institute of Architects (RAIA) released an Environment Policy for architects in September 1994 which forms part of the RAIA Code of Professional Conduct. Prior to releasing the policy, it was recognised that members needed information and education in the area of energy and environment in order to adopt and implement the guide. This document is a report on the scope, work programme and achievements of a project to provide an easy reference resource for architects and other building designers, and bring together a wide range of information and research. It includes the Environment Policy as an appendix. The project produced 24 notes entitled the `Environment Design Guide - energy/environment notes` covering a wide range of topics, and four newsletters. Feedback received from architects to date indicates that the development of the notes has had a positive effect on their knowledge of these issues, resulting in the making of informed design decisions. The topics covered by the notes are expected to expand in 1996 with the preparation of additional notes which provide information on products and sustainable construction.

At present about 90% of the world's energy consumption is met by the fossil carbon fuel used in the form of coal, oil and natural gas. This results into release of vast amounts of waste gas CO 2 into the atmosphere posing a threat to the global environment. Moreover this energy source is not sustainable (renewable) and its use amounts to spending Earth's capital resources. The options to this energy source are biomass energy, hydro power, solar energy, geothermal energy and nuclear energy. The potentials, limitations, geological impact and environmental dangers, if any, of these sources are discussed in brief. Energy conservation through energy efficient systems is also one more option. Problems and potential for change to sustainable energy systems with respect to India and Canada are examined. Finally it is pointed out that the ultimate solution to the world's energy problem lies in population control and population reduction. This will make possible for the world to have a sustainable energy system primarily based on solar energy. (M.G.B.). 15 refs

Emerging market for sustainable food in Bangkok

Directory of Open Access Journals (Sweden)

Peter Oosterveer

2012-09-01

Full Text Available More and more food is traded all over the world, changing the general pattern of food production and consumption dramatically. This transformation includes increasing consumer demand for safe and environmentally friendly produced food. Food is no longer produced only by farmers in the vicinity where consumers can easily observe how they produce their food. Nowadays, food can be produced in Asia and presented on a supermarket’s shelf in Europe, this unknown origin makes consumers more concerned about the safety of their food. Food scandals such as mad cow disease, bird flu, and GMOs make consumers concerned, uncertain and worried about their food. In response to these concerns, modern retailers in many countries improve their sustainable development policy and actively increase the provision of sustainable food. As a newly industrialized country in Southeast Asia, Thailand can be expected to witness a similar increasing domestic demand for sustainable food products, particularly in its urban areas. The general patterns of global change affect Thailand as well, but the specific processes of change differ due to specific conditions of urban Thailand. This paper analyzes the process of change towards sustainable food provision in Bangkok by investigating how consumers and the system of provision interact in retail outlets.

The general conclusion of the seminar can be as follows. In some cases the nuclear power is a source of environment pollution but very often nuclear techniques are now used and certainly more often in the future will be used for environment and human health protection

P-marking of indoor environment and energy use - Considerations prior to certification of energy use

Energy Technology Data Exchange (ETDEWEB)

Wahlstroem, Aasa

2008-02-15

SP Technical Research Institute of Sweden's P-marking quality assurance scheme for buildings, products, services etc., now includes P-marking of the indoor environment and energy use performance of buildings. The rules for the system, which cover new buildings, renovation and existing buildings, are set out in SP's Certification Rules no. SPCR 114E, specifying requirements in respect of both energy use and indoor environment management. Over the last ten years, SP has carried out considerable work in the field of the indoor environment, resulting in the development of a quality assurance system concentrating on achieving a high-quality indoor environment. This quality assurance system has been successfully applied to schools, offices and dwellings. However, the performance of a building is determined not only by a good indoor environment, but also by low impact on the external environment as a result of energy use in the building. In some cases, concentrating on either good indoor environment or energy efficiency may result in an adverse effect on the other aspect, and so the quality assurance system for indoor environments been extended with a section dealing with energy use. This document is a handbook for inspection of documentation concerning quality assurance of energy use (primary energy analysis, determination of energy targets, energy management systems etc.). It can also be helpful for the organisation that is applying for P-marking when drawing up checklists. The document concentrates on requirements for approved certification of energy use in connection with P-marking of indoor environments and energy use in existing buildings: it does not cover requirements for certification of indoor environments. It starts by describing targeting, aims and requirements for P-marking of energy use, followed by presentation of some examples of inspections of collected documentation

Photochemical smog modeling for assessment of potential impacts of different management strategies on air quality of the Bangkok Metropolitan Region, Thailand.

Oanh, Nguyen Thi Kim; Zhang, Baoning

2004-10-01

A photochemical smog model system, the Variable-Grid Urban Airshed Model/Systems Applications International Mesoscale Model (UAM-V/SAIMM), was used to investigate photochemical pollution in the Bangkok Metropolitan Region (BMR). The model system was first applied to simulate a historical photochemical smog episode of two days (January 13-14, 1997) using the 1997 anthropogenic emission database available at the Pollution Control Department and an estimated biogenic emission. The output 1-hr ozone (O3) for BMR, however, did not meet the U.S. Environmental Protection Agency suggested performance criteria. The simulated minimum and maximum O3 values in the domain were much higher than the observations. Multiple model runs with different precursor emission reduction scenarios showed that the best model performance with the simulated 1-hr O3 meeting all the criteria was obtained when the volatile organic compound (VOC) and oxides of nitrogen (NOx) emission from mobile source reduced by 50% and carbon monoxide by 20% from the original database. Various combinations of anthropogenic and biogenic emissions in Bangkok and surrounding provinces were simulated to assess the contribution of different sources to O3 pollution in the city. O3 formation in Bangkok was found to be more VOC-sensitive than NOx-sensitive. To attain the Thailand ambient air quality standard for 1-hr O3 of 100 ppb, VOC emission in BMR should be reduced by 50-60%. Management strategies considered in the scenario study consist of Stage I, Stage II vapor control, replacement of two-stroke by four-stroke motorcycles, 100% compressed natural gas bus, 100% natural gas-fired power plants, and replacement of methyltertiarybutylether by ethanol as an additive for gasoline.

Photochemical smog pollution in the Bangkok Metropolitan Region of Thailand in relation to O 3 precursor concentrations and meteorological conditions

Science.gov (United States)

Zhang, B.-N.; Kim Oanh, N. T.

Analysis of photochemical pollution was done using the available 5-yr monitoring data (1996-2000) from 11 monitoring stations in Bangkok and 5 stations in other surrounding provinces, i.e. the Bangkok Metropolitan Region (BMR). Status and trend of O 3 as well as the monthly and diurnal variations were analyzed in relation to the local meteorological conditions as well as the regional transport of pollutants associated with the monsoon. The O 3 in Bangkok was found to be typical for the polluted urban areas with a lower concentration in the city center, especially at curbside stations, and higher concentration at the downwind locations. O 3 pollution was highest in 1997 with the maximum hourly average of 370 ppbv and the total hours exceeding the national hourly O 3 standard (100 ppbv) of 314 h, which is most likely related to the strong El Niño and the forest fire in Southeast Asia in this year. Meteorology-unadjusted trend shows a slight increase in O 3 from 1998 to 2000. Local emission and photochemistry are mainly responsible for O 3 episodes in the BMR. Seasonal fluctuations of O 3, however, were found to relate to the regional transport associated with the Asian monsoon. Highest O 3 pollution was found in the period from January to April (winter and local summer) and lowest during mid-rainy season, August. The O 3 increase isopleth diagram was constructed which shows that O 3 production in BMR is effective when the NO x/NMHC ratio is in the range of 0.04-0.15 with optimum ratio of around 0.07. Seasonal variations in NO x/NMHC ratios are consistent with the O 3 variations, i.e., optimum in summer (0.07), followed by winter (0.05), and the lowest in rainy season (0.03).

In the late 1970s, UNEP compiled three comprehensive reports on the the environmental impacts of the production and use of fossil fuels, nuclear energy and renewable energy sources. In 1987 it was decided to update the volume on renewable energy since knowledge of biofuels and their effects on the environment had greatly improved. Among many innovations, Brazil's decision to embark on a major, and now successful, programme to produce ethanol from sugarcane as a substitute vehicle fuel is one of the most significant. At the same time, energy tree crops, agroforestry systems and the use of plantations for environmental improvement have become issues of key importance to sustainable development in developing countries. Biomass fuels, of course, have always been important in terms of the numbers of people who use them; the significant change during the 1980s was that the potential advantages of these fuels took on a new significance in the light of environmental degradation and related issues such as greenhouse warming. The biomass fuels began to be considered as attractive energy sources in their own right - not simply as 'last resort' fuels for developing countries with only limited energy options. While this development may solve some environmental problems, it certainly raises others - the improper utilization of biomass fuels in the past has been responsible for deforestation, desertification and the ill health of many millions of the women in developing countries who use biomass fuels in unventilated huts. These issues currently affect about half of the world population. The new UNEP study was intended to provide an up-to-date evaluation of the environmental issues raised by the use of biomass fuels, and hence to reduce or eliminate their adverse impacts while

Energy, pollution, environment and health

International Nuclear Information System (INIS)

1999-01-01

Many of the major environmental problems of today, such as climate change, air pollution, acidification of lakes and forests, deforestation and desertification, share a common causal factor: energy - its production, transformation and final use. The burning of fossil fuels has already contributed to acidification of lakes and forests, and threatens to alter the world's climate. Traditional open fires cause indoor air pollution, thereby harming the health of women and children in the Third World. In many developing countries, the disappearing forest base is increasingly unable to supply enough wood for energy needs, leading to even greater pressure on forests, which in turn can lead to desertification. Nuclear reactor accidents may release large quantities of radioactive materials, and hydro dams may fail and inundate large areas of land. Indeed, every energy system has some impact on health and the environment, either affecting the same group of people who enjoy the benefits: the exposure of a small group to fumes from a poorly vented common cooking device; or a different group: acid rain in one country caused by the burning of fossil fuels in another, or harm to the health of future generations from today's radioactive nuclear waste. During the past two decades, these energy- environment impacts have become so serious that they may limit further growth of the world's energy economy. Consequently, these problems are now being examined more closely by decision makers throughout the world, as well as by the general public. In addition, it has become clear that energy cannot be viewed in isolation and that pollution, environment and health issues must be integrated into the development of national and international energy policies, so that the adverse impacts of energy can be reduced. To do this, the relationships among different energy systems and their impacts need to be defined clearly. To that end, UNEP has convened conferences on this topic and prepared several

Energy and the environment in Eastern Europe

International Nuclear Information System (INIS)

Kramer, J.M.

1991-01-01

This paper reports that three preeminent factors determine the nexus between energy policies and the environment in Eastern Europe. Economic planners in the region traditionally have emphasized supply-side policies to expand the amount, rather than demand-side policies to limit the consumption, of energy. Consequently, the East European economies have developed, in the words of Hungarian economists, an insatiable appetite for fuels and power that engenders among them a persisting propensity to overconsume these resources. All states in the region continue to devote between 40 and 45 percent of their total investments in industry to increase the indigenous production of fuels and power. The quality of the environment suffers considerably from these policies. The more energy an economy consumes (all other things being equal), the more wastes it creates, and so the more it pollutes the environment. Further, the enormous output of fiscal resources that these states devote to increasing their supply of energy severely constrains their capacity to pursue other investment opportunities, including opportunities to protect the environment

Changing Media Ecologies in Thailand: Women's Online Participation in the 2013/2014 Bangkok Protests

Directory of Open Access Journals (Sweden)

Olivia Guntarik

2016-12-01

Full Text Available Traditionally marginalized groups now have more access to new and unconventional means to participate in politics, transforming the media ecologies of existing political environments. Contemporary feminist scholarship has centered on how women use new media technologies to serve political agendas. However, this literature focuses predominately on women in the West, while women in developing countries, or Asia more generally, have been largely excluded from analysis. This article aims to fill in this gap by examining Thai women’s online activities during the 2013/2014 Bangkok political protests. Specifically, we ask how the rise of social and digital media has altered what it means to participate politically in the context of Thai women’s present-day political experience. To answer this question we looked at how women resorted to various digital and social media to discuss women’s rights and political issues, including Yingluck Shinawatra’s political leadership as Thailand’s first female prime minister (2011-2014. Moving beyond traditional notions of participation, we argue that there is a need to recognize the emerging dynamics of women’s online engagement in the political landscape of Thailand. In the context of a totalitarian state, speaking out against the ruling authority online embodies an additional layer of citizen resistance, a feature of digital life that is often taken for granted in Western democracies.

2013-06-01

Previous studies suggested that aerosol optical depth (AOD) from the Earth Observing System satellite retrievals could be used for inference of ground-level air quality in various locations. This application may be appropriate if pollution in elevated atmospheric layers is insignificant. This study investigated the significance of elevated air pollution layers over the Bangkok Metropolitan Region (BMR) from all available aerosol layer scenes taken from Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) for years 2007 to 2011. The results show that biomass burning smoke layers alone were the most frequently observed. The smoke layers accounted for high AOD variations and increased AOD levels. In the dry seasons, the smoke layers alone with high AOD levels were likely brought to the BMR via northeasterly to easterly prevailing winds and found at altitudes above the typical BMR mixing heights of approximately 0.7 to 1.5 km. The smoke should be attributed to biomass burning emissions outside the BMR.

This research proposes a design and verification of an off-grid photovoltaic system (PVS) for electric motorcycle charging station to be located in King’s Mongkut’s University of Technology Thonburi, Bangkok, Thailand. The system is designed to work independently (off-grid) and it must be able to fully charge the batteries of a typical passenger electric motorcycle every evening. A 1,000W Toyotron electric motorcycle is chosen for this study. It carries five units of 12.8V 20Ah batteries in series; hence its maximum energy requirement per day is 1,200Wh. An assessment of solar irradiation data and the Generation Factor in Bangkok, Thailand suggests that the charging system consists of one 500W PV panel, an MPPT charge controller, 48V 150Ah battery, a 1,000W DC to AC inverter and other safety devices such as fuses and breakers. An experiment is conducted to verify the viability of the off-grid PVS charging station by collecting the total daily energy generation data in the raining season and winter. The data suggests that the designed off-grid solar power charging station for electric motorcycle is able to supply sufficient energy for daily charging requirements.

Effective ways to integrate human life quality, environmental pollution mitigation and efficient waste management strategies are becoming a crisis challenge for sustainable urban development. The aims of this study are: (1) to evaluate and recommend an optimum Urban Green Space (UGS) area for the Bangkok Metropolitan Administration (BMA); and (2) to quantify potential renewable resources including electricity generation and potential nutrient recovery from generated ash. Green House Gases (GHGs) emissions from the management of Green Residues (GR) produced in a recommended UGS expansion are estimated and compared with those from the existing BMA waste management practice. Results obtained from this study indicate that an increase in UGS from its current 2.02% to 22.4% of the BMA urban area is recommended. This optimum value is primarily due to the area needed as living space for its population. At this scale, GR produced of about 334kt·y -1 may be used to generate electricity at the rate of 206GWh·y -1 by employing incineration technology. Additionally, instead of going to landfill, phosphorus (P) contained in the ash of 1077 t P·y -1 could be recovered to produce P fertilizer to be recycled for agricultural cultivation. Income earned from selling these products is found to offset all of the operational cost of the proposed GR management methodology itself plus 7% of the cost of BMA's Municipal Solid Waste (MSW) operations. About 70% of the current GHGs emission may be reduced based on incineration simulation. Copyright © 2016 Elsevier Ltd. All rights reserved.

2018-02-01

The motorcycle taxi drivers of Bangkok have been heavily exposed to high concentrations of PM 10 (particulate matter with an aerodynamic diameter ≤10 μm), and the impact of this on their lungs has been neither documented nor studied. This study examines the association between exposure to PM 10 and lung function decline among motorcycle taxi drivers. A cross-sectional study was conducted in Bangkok between two groups: a subject group of motorcycle taxi drivers and control group of enclosed vehicle taxi drivers. The findings of the Thailand Pollution Control Department were used to estimate the annual ambient PM 10 concentration levels in the metropolis. Pulmonary functions of motorcycle taxi drivers and enclosed vehicle taxi drivers were measured and compared using the Mann-Whitney test. Multiple linear regression analysis was applied to estimate the effects of PM 10 exposure on the lung function of motorcycle taxi drivers. A total of 1283 motorcycle taxi drivers and 600 taxi drivers were investigated. The mean forced expiratory volume in 1 sec/forced vital capacity (FEV 1 /FVC) of the motorcycle taxi drivers was significantly lower than that of the taxi drivers (P Organization (WHO) vehicular emission standards should be recognized and eventually enforced.

Nutramon, Tamsanya; Supachart, Chungpaibulpatana

2009-01-01

The influence of different driving cycles on their exhaust emissions and fuel consumption rate of gasoline passenger car was investigated in Bangkok based on the actual measurements obtained from a test vehicle driving on a standard chassis dynamometer. A newly established Bangkok driving cycle (BDC) and the European driving cycle (EDC) which is presently adopted as the legislative cycle for testing automobiles registered in Thailand were used. The newly developed BDC is constructed using the driving characteristic data obtained from the real on-road driving tests along selected traffic routes. A method for selecting appropriate road routes for real driving tests is also introduced. Variations of keyed driving parameters of BDC with different driving cycles were discussed. The results showed that the HC and CO emission factors of BDC are almost two and four times greater than those of EDC, respectively. Although the difference in the NOx emission factor is small, the value from BDC is still greater than that of EDC by 10%. Under BDC, the test vehicle consumes fuel about 25% more than it does under EDC. All these differences are mainly attributed to the greater proportion of idle periods and higher fluctuations of vehicle speed in the BDC cycle. This result indicated that the exhausted emissions and fuel consumption of vehicles obtained from tests under the legislative modal-type driving cycle (EDC) are significantly different from those actually produced under real traffic conditions especially during peak periods.

Feng, Lujia; Mears, Laine; Beaufort, Cleveland; Schulte, Joerg

2016-01-01

Highlights: • Single objective and multicriteria optimization approaches are proposed. • Objectives of energy, economy, and environment are proved conflicting. • 3-input-5-output energy supply system of an automotive plant is studied. - Abstract: Increasing attention has recently been drawn to energy consumption in manufacturing plants. Facing the challenges from reducing emissions coupled with rising raw material prices and energy costs, manufacturers are trying to balance the energy usage strategy among the total energy consumption, economy, and environment, which can be self-conflicting at times. In this paper, energy systems in manufacturing environments are reviewed, and the current status of onsite energy system and renewable energy usage are discussed. Single objective and multicriteria optimization approaches are effectively formulated for making the best use of energy delivered to the production processes. Energy supply operation suggestions based on the optimization results are obtained. Finally, an example from an automotive assembly manufacturer is described to demonstrate the energy usage in the current manufacturing plants and how the optimization approaches can be applied to satisfy the energy management objectives. According to the optimization results, in an energy oriented operation, it takes 35% more in monetary cost; while in an economy oriented operation, it takes 17% more in megawatt hour energy supply and tends to rely more on the inexpensive renewable energy.

A worldwide perspective on energy, environment and sustainable development

International Nuclear Information System (INIS)

Dincer, Ibrahim; Rosen, Marc A.

1998-01-01

Problems with energy supply and use are related not only to global warming, but also to such environmental concerns as air pollution, ozone depletion forest destruction and emission of radioactive substances. These issues must be taken into consideration simultaneously if humanity is to achieve a bright energy future with minimal environmental impacts. Much evidence exists which suggests that the future will be negatively impacted if humans keep degrading the environment. There is an intimate connection between energy, the environment and sustainable development. A society seeking sustainable development ideally must utilise only energy resources which cause no environmental impact (e.g. which release no emissions to the environment). However, since all energy resources lead to some environmental impact, it is reasonable to suggest that some (not all) of the concerns regarding the limitations imposed on sustainable development by environmental emissions and their negative impacts can be part overcome through increased energy efficiency. A strong relation clearly exists between energy efficiency and environmental impact since, for the same services or products, less resource utilisation and pollution is normally associated with higher efficiency processes. Anticipated patterns of future energy use and consequent environmental impact (Focusing on acid precipitation, stratospheric ozone depletion and the greenhouse effect) are comprehensively discussed in this paper. Also, some solutions to current environmental issues in terms of energy conservation and renewable energy technologies are identified and some theoretical and practical limitations on increased energy efficiency are explained. The relations between energy and sustainable development, and between the environment and sustainable development, are described, and in illustrative example is presented. Throughout the paper several issues relating to energy, environment and sustainable development are examined

The objective of this report is to give Danish investors, consultants, and subcontractors With interest in the Czech environment and energy sector, a basis for evaluating its market opportunities. Furthermore, the report will provide the reader With an overview of potential finance sources for projects within the environment and energy sector. With the prospects of EU membership, the Czech Republic has put a great effort into improving the country's environmental conditions as well as restructuring its energy sector. In particular in the area of the environment, the Czech Republic has experienced considerable progress. However, in several environmental areas, the Czech Republic is still lacking behind other EU countries. The process of meeting the environmental standards of the EU continues to demand large investments, especially within the field of water and waste treatment. In the process of adapting to the requirements of the EU in the field of the environment, the Czech Republic can expect to receive around EUR 615 million in EU funds betaveen 2004 and 2006. The Czech energy sector is the most air-polluting sector in the country and there is a general demand for knove-hove and technology in the field of energy efficiency and udlisation of renewable energy. Renewable energy makes up only 2% of the Czech Republic's total energy production. The goal of the Czech government is to increase the share to 8% before 2010.

Ziegler, A. D.; Velasco, E.; Ho, K. J.

2013-12-01

Khlong (canal) boats are a unique mass transport alternative in the congested city of Bangkok. Canals and rivers provide exclusive transit-ways for reducing the commuting time of thousands of city residents daily. However, as a consequence of the service characteristics and boats design and state of repair, they can represent a potential public health risk and an important source of black carbon and greenhouse gases. This work quantifies commuter exposure to black carbon, CO and noise when waiting for and travelling in these diesel fueled boats. Exposure to toxic pollutants and acute noise is similar or worse than for other transportation modes. Mean black carbon concentrations observed at one busy pier and along the main canal were much higher than ambient concentrations at sites impacted by vehicular traffic. Concentrations of CO were similar to those reported for roadside areas of Bangkok. The equivalent continuous sound levels registered at the landing pier were similar to those reported for roadsides, but values recorded inside the boats were significantly higher. We believe that the boat service is a viable alternative mode of mass transport, but public safety could be improved to provide a high quality service, comparable to modern rail systems or emerging bus rapid transit systems. These investments would also contribute to reduce the emission of black carbon and other greenhouse and toxic pollutants.

A study of enterobiasis and its correlation with various factors that could potentially influence the rate of infection was conducted among 3,621 primary school children (five to ten years old), drawn from sixteen schools in Bang Khun Thian District, Bangkok. Diagnosis was by the transparent tape swab technique, which was used to recover Enterobius vermicularis eggs from the perianal region. The transparent tape swabs were then placed on slides for examination by light microscopy. The average rate of infection for the group was 21.57%. No statistically significant differences were found between the male and female children. The younger children had a higher rate of infection. Subjects from schools located in industrial and metropolitan areas showed slightly higher rates of infection than those from agricultural areas. Data from the questionnaires in the study indicated that factors such as parental socio-economic status (occupational, income and education) and the children's personal hygiene contributed to the varying rates of infection.

Attempt of report on the present situation of coping with an imminent energy crisis and at the same time saving an environment worth living in with stress being laid on energy policy, economical growth, energy supply and -saving. Without a reasonable extension of the nuclear energy, there won't be sufficient energy basis in the FRG in the future. In the author's opinion, already in the 80ies, economical growth, employment, and living standards will be in danger, to an unjustifiable extent. An evalution of questionnaires on environmental problems shows, among other things, that increasingly more inhabitants of the FRG are ready to make sacrifices for measures of environment protection (in May 77 : 73%).

To establish a general view of food habits in Thailand, and to make a quantitative assessment of rice dependency of Thai people. Cross-sectional study. Community. 52 non-smoking and non-habitually drinking adult women in Bangkok participated in the study. The participants offered 24 h food duplicates and peripheral blood samples, and underwent clinical examination including anthropometry. The duplicates were subjected to nutritional evaluation taking advantage of the Thai food composition tables (FCTs), and analyzed for eight nutrient elements by inductively coupled plasma mass spectrometry (ICP-MS). The participants took 1630 kcal from 55 g protein (63% from animal sources), 57 g lipid (mostly from vegetable oil), and 224 g carbohydrate (60% from rice) daily. Nutrient intake at lunch was as large as that at dinner. About a half of the women had insufficient energy intake (ie 120%). Protein intake was sufficient in most cases, whereas lipid intake was in excess in more than a half of the women. Ca, Fe, Mg, Zn and possibly P intakes were below the RDA values in many participants. FCT-based estimates agreed well with the ICP-MS measures in cases of Fe and Ca but tended to be greater than the measures by 50% with regard to P. Lunch as substantial as dinner for Thai urbanites. There was a marked dependency on rice as an energy source. Whereas protein intake is generally sufficient, the intake of Ca (and to a lesser extent Fe) was insufficient in a majority of the study participants.

This study was aimed at developing a better understanding of urban household energy consumption in Thailand through a series of in-depth household energy surveys. Households in urban areas used electricity, LPG, charcoal and fuelwood. Traditional biomass fuels such as husk and dung, as well as kerosene, were essentially not used in urban households. Nearly all households used electricity and most households used LPG. Some households used more than one fuel for cooking, particularly LPG and charcoal. There was a great difference in electricity used between the households in Bangkok and other urban areas. Most households in the study areas used LPG stove or burners for cooking. But charcoal stoves were also used by many households for specific culinary purposes. Electric rice-cookers are widely used for convenience. The study suggests that the number of households using charcoal stoves will decrease gradually and fuelwood use will disappear. Saturation rates for refrigerators and colour television sets were very high and air conditioners were common in Bangkok. Some users may be unaware of the benefits of LPG as a cooking fuel. To improve indoor air quality and cooking safety and reduce pressures on forests from commercial fuelwood use, measures to promote LPG should be undertaken. The government should also provide information about efficient appliances and electricity conservation. (Author)

The development of man's use of energy, from earliest times to the present, is briefly sketched. The present energy problem is discussed under three headings: availability of energy (standard of living of developed and developing countries; rate of depletion of non-renewable energy sources with special reference to oil); price (effect on practical availability); environmental pollution (hazards to workers and public; 'greenhouse effect' due to carbon dioxide; radioactivity in the environment due to the operations associated with the use of nuclear power; comparison of hazards associated with oil, coal and nuclear power); response to the energy problem (economy of use of existing energy sources; development of renewable sources; nuclear fusion); what future for industrial society; what is a post-industrial society (sociological and ethical aspects).

A vision to supply microelectronic devices without batteries making them perpetual or extending time of service in battery-oriented mobile supply schemes is the driving force of the research related to ambient energy harvesting. Energy harnessing aims thus at extracting energy from various ambient energy "pools", which generally are cost- or powerineffective to be scaled up for full-size, power-plant energy generation schemes supplying energy in electric form. These include - but are not limited to - waste heat, electromagnetic hum, vibrations, or human-generated power in addition to traditional renewable energy resources like water flow, tidal and wind energy or sun radiation which can also be exploited at the miniature scale by energy scavengers. However, in case of taking advantage of energy harvesting strategies to power up sensors monitoring environment inside buildings adaptable energy sources are restrained to only some which additionally are limited in spatial and temporal accessibility as well as available power. The paper explores experimentally an energy harvesting scheme exploiting human kinesis applicable in indoor environment for supplying a wireless indoor micro-system, monitoring ambient air properties (pressure, humidity and temperature).

Highlights: •An improved environment DEA cross-model method is proposed. •Energy and environment efficiency analysis framework of complex chemical processes is obtained. •This proposed method is efficient in energy-saving and emission reduction of complex chemical processes. -- Abstract: The complex chemical process is a high pollution and high energy consumption industrial process. Therefore, it is very important to analyze and evaluate the energy and environment efficiency of the complex chemical process. Data Envelopment Analysis (DEA) is used to evaluate the relative effectiveness of decision-making units (DMUs). However, the traditional DEA method usually cannot genuinely distinguish the effective and inefficient DMU due to its extreme or unreasonable weight distribution of input and output variables. Therefore, this paper proposes an energy and environment efficiency analysis method based on an improved environment DEA cross-model (DEACM) method. The inputs of the complex chemical process are divided into energy and non-energy inputs. Meanwhile, the outputs are divided into desirable and undesirable outputs. And then the energy and environment performance index (EEPI) based on the cross evaluation is used to represent the overall performance of each DMU. Moreover, the improvement direction of energy-saving and carbon emission reduction of each inefficiency DMU is quantitatively obtained based on the self-evaluation model of the improved environment DEACM. The results show that the improved environment DEACM method has a better effective discrimination than the original DEA method by analyzing the energy and environment efficiency of the ethylene production process in complex chemical processes, and it can obtain the potential of energy-saving and carbon emission reduction of ethylene plants, especially the improvement direction of inefficient DMUs to improve energy efficiency and reduce carbon emission.

Full Text Available Metro systems act as fast and efficient transport systems for many modern metropolises; however, enhancing higher usage of such systems often conflicts with providing suitable accessibility options. The traditional approach of metro accessibility studies seems to be an ineffective measure to gage sustainable access in which the equal rights of all users are taken into account. Bangkok Metropolitan Region (BMR transportation has increasingly relied on the role of two mass rapid transport systems publicly called “BTS Skytrain” and “MRT Subway”, due to limited availability of land and massive road congestion; however, access to such transit arguably treats some vulnerable groups, especially women, the elderly and disabled people unfairly. This study constructs a multi-dimensional assessment of accessibility considerations to scrutinize how user groups access metro services based on BMR empirical case. 600 individual passengers at various stations were asked to rate the questionnaire that simultaneously considers accessibility aspects of spatial, feeder connectivity, temporal, comfort/safety, psychosocial and other dimensions. It was interestingly found by user disaggregated accessibility model that the lower the accessibility perceptions—related uncomfortable and unsafe environment conditions, the greater the equitable access to services, as illustrated by MRT — Hua Lumphong and MRT — Petchaburi stations. The study suggests that, to balance the access priorities of groups on services, policy actions should emphasize acceptably safe access for individuals, cost efficient feeder services connecting the metro lines, socioeconomic influences and time allocation. Insightful discussions on integrated approach balancing different dimensions of accessibility and recommendations would contribute to accessibility-based knowledge and potential propensity to use the public transits towards transport sustainability.

Fossil fuel reserves are diminishing rapidly across the world. Greenhouse gas emissions, climatic changes and global warming have a direct impact on the environment. A secure and accessible supply of energy is very crucial for the sustainability of modern societies. There is an urgent need for a quicker switch over of energy systems from conventional to renewable that are sustainable and can meet the present and projected world energy demand. Renewable energy has a large potential to become the fuel of the future. The present study is aimed to explore such potential and achievements in India. India is expected to have high growth rate in energy demand over the coming years due to its huge population and rapid economic development. The renewable energy prospects/spectrums of India have been highlighted. (author)

Globally, buildings are responsible for approximately 40% of the total world annual energy consumption. Most of this energy is for the provision of lighting, heating, cooling, and air conditioning. Increasing awareness of the environmental impact of CO 2 and NO x emissions and CFCs triggered a renewed interest in environmentally friendly cooling, and heating technologies. Under the 1997 Montreal Protocol, governments agreed to phase out chemicals used as refrigerants that have the potential to destroy stratospheric ozone. It was therefore considered desirable to reduce energy consumption and decrease the rate of depletion of world energy reserves and pollution of the environment. One way of reducing building energy consumption is to design building, which are more economical in their use of energy for heating, lighting, cooling, ventilation and hot water supply. Passive measures, particularly natural or hybrid ventilation rather than air-conditioning, can dramatically reduce primary energy consumption. However, exploitation of renewable energy in buildings and agricultural greenhouses can, also, significantly contribute towards reducing dependency on fossil fuels. Therefore, promoting innovative renewable applications and reinforcing the renewable energy market will contribute to preservation of the ecosystem by reducing emissions at local and global levels. This will also contribute to the amelioration of environmental conditions by replacing conventional fuels with renewable energies that produce no air pollution or greenhouse gases. The provision of good indoor environmental quality while achieving energy and cost-efficient operation of the heating, ventilating and air-conditioning (HVAC) plants in buildings represents a multi-variant problem. The comfort of building occupants is dependent on many environmental parameters including air speed, temperature, relative humidity and quality in addition to lighting and noise. The overall objective is to provide a high

Dilemmas for China: Energy, Economy and Environment

Full Text Available China’s current national policies promote high levels of economic growth, transforming China into a “world factory”, but at a high cost in terms of energy and the environment. At the same time, this growth and transformation also forms the backbone of China’s economy, underpinning social stability. China faces a dilemma to reconcile its economy, energy system and environmental security. Each aspect of this triad is discussed in this study to illuminate the challenges faced by China, and China’s dilemma in energy, economy and environment is analyzed from the perspective of its participation in current global supply chains. While China must import a significant proportion of its energy and a large proportion of primary materials, a large share of these imports are returned to the global market as industrial exports. China is bound by its own course of action and unable to radically change its position for the foreseeable future as the road to economic development and employment stability is through policies built on exports and shifting development models, presenting a tough socio-economic trade-off. China’s growth challenges are discussed as an example of challenges more broadly faced in the developing world. China’s success or failure in achieving a sustainable developmental pattern will inevitably have a significant influence on the global environment.

Energy conservation and the environment: conflict or complement

Energy Technology Data Exchange (ETDEWEB)

Schipper, L.

1978-09-01

The policy discussion following the Oil Embargo was clouded with fears of a return to a primitive existence based on drastically reduced energy inputs to society, or, on the other hand, an abandoning of environmental goals, allegedly a major barrier to development of new energy supplies. Often the energy use associated with environmental improvements was cited as a reason for expanding energy supplies, as if to say that a conflict existed between a clean environment and reductions in energy use. Or it was argued that a relaxation of environmental goals would lower the direct costs of harvesting and using energy and thereby alleviate the need for energy conservation. It has also been argued that the geopolitics of energy alone will force us to substitute riskier or ''dirtier'' energy sources for relatively clean oil and gas. Indeed, there is no question that the relationship among energy, the environment, and economic well-being is complicated. This essay sorts out many of the confusing aspects in order to show how goals relating to the efficient use of energy are aligned both with traditional economic goals and with modern environmental goals. To do this the author analyzes in depth the role of energy in the economy and, using examples, traces the origins of many of the misconceptions about that role--misconceptions that have inhibited a profound discussion of energy-related goals.

In the situation that world's population, especially in developing countries, is rapidly growing, humankind is facing to global problems that they cannot steadily live unless they find individual places to live, obtain foods, and peacefully get energy necessary for living for centuries. For this purpose, humankind has to think what behavior they should take in the finite environment, talk, agree and execute. Though energy has been long respected as a symbol for improving living, demanded and used, they have come to limit the use making the global environment more serious. If there is sufficient energy not loading cost to the environment. If nuclear energy regarded as such one sustain the resource for long and has market competitiveness. What situation of realization of compensating new energy is now in the case the use of nuclear energy is restricted by the society fearing radioactivity. If there are promising ones for the future. One concerning with the study of energy cannot go without knowing these. The statistical materials compiled here are thought to be useful for that purpose, and are collected mainly from ones viewing future prediction based on past practices. Studies on the prediction is so important to have future measures that these data bases are expected to be improved for better accuracy. (author)

Asian megacities have severe pollution problems in both coastal and urban areas. In addition, the groundwater potential has decreased and land subsidence has occurred because of intensive groundwater pumping in urban areas. To prevent the adverse effects of urbanization on groundwater quality, it is necessary to confirm the changes in groundwater flow and contaminant transport caused by urbanization. We examined the effects of urbanization on contaminant transport in groundwater. The research areas were located around Bangkok, Thailand, and akarta, Indonesia, cities with populations of approximately 8 and 12 million, respectively. Each metropolitan city is located on a river delta and is adjacent to a bay. We measured the water level and collected water samples at boreholes at multiple depths (100 to 200 m) in 2004 and 2006 in Bangkok and Jakarta, respectively. The current hydraulic potential is below sea level in both cities because of prior excess abstraction of groundwater. As a result, the direction of groundwater flow is now downward in the coastal area. The Cl - concentration and δ 18 O distributions in groundwater suggest that the decline in hydraulic potential has caused the intrusion of seawater and shallow groundwater into deep groundwater. Concentrations of Mn and NO3 - -N in groundwater suggest the intrusion of these contaminants from shallow to deep aquifers with downward groundwater flow and implies an accumulation of contaminants in deep aquifers. Therefore, it is important to recognize the possibility of future contaminant transport with the discharge of deep groundwater into the sea after the recovery of groundwater potential in the coastal areas

2005-12-01

Full Text Available Solar Energy has been acknowledged as a free and infinite source of energy. In Built Environment (BE, solar energy has been used since pre-historic time. Many improvements and technologies .have been developed with respect to their potential. As solar supplies free energy, the issues with regard to their development in the BE will be examined. The solar energy is used in building either in Passive Solar Design (PSD or Active Solar Design (ASD. Rapid development in BE has caused global warming effect where the heating and cooling of the building contribute to half the total energy consumption of the nation and the construction industry leading to CO2 emission level at 300 million tonnes. It is found that solar energy produces different energy performances which result from different building technique that affected the environment in various ways. Whether or not the energy performances depend on the materials used, the equipment installed in the building or the energy sources supplied to the building , the improvement and development of solar energy still continues and grows.

Assessing the co-benefits of greenhouse gas reduction: Health benefits of particulate matter related inspection and maintenance programs in Bangkok, Thailand

Since the 1990s, the capital city of Thailand, Bangkok has been suffering from severe ambient particulate matter (PM) pollution mainly attributable to its wide use of diesel-fueled vehicles and motorcycles with poor emission performance. While the Thai government strives to reduce emissions from transportation through enforcing policy measures, the link between specific control policies and associated health impacts is inadequately studied. This link is especially important in exploring the co-benefits of greenhouse gas emissions reductions, which often brings reduction in other pollutants such as PM. This paper quantifies the health benefits potentially achieved by the new PM-related I/M programs targeting all diesel vehicles and motorcycles in the Bangkok Metropolitan Area (BMA). The benefits are estimated by using a framework that integrates policy scenario development, exposure assessment, exposure-response assessment and economic valuation. The results indicate that the total health damage due to the year 2000 PM emissions from vehicles in the BMA was equivalent to 2.4% of Thailand's GDP. Under the business-as-usual (BAU) scenario, total vehicular PM emissions in the BMA will increase considerably over time due to the rapid growth in vehicle population, even if the fleet average emission rates are projected to decrease over time as the result of participation of Thailand in post-Copenhagen climate change strategies. By 2015, the total health damage is estimated to increase by 2.5 times relative to the year 2000. However, control policies targeting PM emissions from automobiles, such as the PM-oriented I/M programs, could yield substantial health benefits relative to the BAU scenario, and serve as co-benefits of greenhouse gas control strategies. Despite uncertainty associated with the key assumptions used to estimate benefits, we find that with a high level confidence, the I/M programs will produce health benefits whose economic impacts considerably outweigh

In prospecting the role of nuclear energy in a future society, it is necessary to foresee the social attitudes towards energy, economy and environment, and to analyze their interactions with the exploitation of nuclear energy itself. As those issues, this article looks upon the change of the socio-economic environment, the concerns about nuclear power and eco-environment, and the sustainability and limits of the energy resources, etc. With this perception, the so-called SWOT analysis is employed to identify the internal strengths (S) and/or weaknesses (W) of nuclear energy compared with other energy competitors on the basis of the evaluation of the external factors which are likely to play the roles of opportunities (O) for and/or threats (T) against the technological change in nuclear energy.

Young people and environment, technology, nuclear energy in France

International Nuclear Information System (INIS)

Bernhardt-Crochet, L.

1995-01-01

Young people have a particular attitude on the questions about environment and energy, and also about technology. Several inquiries show that young people are more aware of environmental questions than their elders. Their anxiety is bigger against pollution than the average of French people and it seems that they are more attentive to dangers for the planet: it is the sign of a broader opening on the world. Young people are ready to adhere to a group or association for environment and have sympathy for ecologists; they have hostility against nuclear energy. Age and education level have to be specified to complicate the question. This contribution gives some elements about the opinion of young people between 15-25 years old on environment, technology and nuclear energy in France. (N.C.)

Energy, economics, environment and politics

Foster, R.J.

1993-01-01

The pressure on the Earth's environment and resources is the ultimate result of population growth and the only humane means available for stabilizing world population is to increase per capita living standards in the developing countries. However, this will require a very large increase in global energy consumption. If, as at present, the energy demand is met largely by fossil fuels, atmospheric concentrations of CO 2 will rise rapidly. Until the end of the century, and perhaps beyond it, any actions to control CO 2 emissions will be taken for precautionary reasons alone, because no reliable basis will exist for predicting their global (or regional) impact on the climate. The sustainability of the natural environment is also under threat from human activities such as the clearing of forests for crop-growing and grazing. The resulting elimination of habitats for, and genetic variability in, the victor is as serious a concern as global warming. The economic and social consequences of rigidly curtailing the growth of energy use in developed countries would be severe, and in developing countries extreme; even then greenhouse gas build up could only be slowed not prevented. On the other hand, a wealthier world would be more able to bear the financial burden of protecting biodiversity. It is concluded that since the developed countries on whom the main cost would have to fall, adequate effort into both biodiversity and greenhouse gas reduction, biodiversity must take procedence.

1991-01-01

Pacific Islands have experienced low economic growth during the 1980s, and face significant energy problems. Petroleum products are imported at very high prices and biofuel use often leads to resource over-exploitation. However, perhaps the most basic energy-environment concern is the potential for sea level rise. Some Pacific Island nations would vanish altogether, while others would lose their most productive areas. (author)

US National energy policy: conservation and environment

Michna, J.; Bednarz, L.M.

2004-01-01

The paper presents extracts from an extended review devoted to recent changes and current trends in the national energy policy pursued in the USA. In 2001 the President Bush proposed an energy strategy for the period to 2025 that would promote energy conservation, repair and expand energy infrastructure, and increase energy supply while protecting the environment. The material stresses the importance of a sound national energy policy addressing supply, energy distribution and conservation. Well - illustrated data are given on the energy production and consumption (total, per capita, per $, by category, by fuel, etc.) and on the emissions (by sector, by fuel, by region, etc.). Giving an accurate account of the current situation with energy in America and a vision of its development for the first quarter of our century, these data are helpful for analyzing the national energy policies in other countries, post - transitional included.

There is increasing concern about the negative psychological effects of excessive use of various electronic media by adolescents but the monitoring of these behaviors in low- and middle-income countries has some methodological flaws. Assess the use of all types of electronic media among secondary school students in Bangkok, Thailand. A stratified random sample of students from four schools in Bangkok completed a modified version of a questionnaire used in a major study in the United States. Among the 768 participants, 443 (57.7%) were female and 325 (42.3%) were male; their mean (sd) age was 15.4 (1.5) years. Almost all respondents had easy access to multiple types of electronic media; 94% had mobile phones, 77% had a television in their bedroom, and 47% had internet access in their bedroom. Over the prior day 39% had watched television shows or movies for more than 3 hours, 28% spent more than 3 hours on social networking sites, 25% listened to music for more than 3 hours, and 18% played computer games for more than 3 hours. Overall, 27% reported using electronic devices for more than 12 hours in the previous day. Only 19% reported parental rules about the use of electronic devices in the home that were regularly enforced. Time engaged in the various activities was not related to parental education or, with the exception of time playing computer games, to students' grade point average. Younger students and male students spent less time than older students and female students using these devices to engage in interactive social activities (e.g., talking on the phone or social networking), while male students spent much more time than female students playing games on the devices. Adolescents spend a substantial part of every single day using different types of electronic devices. Longitudinal studies with precise time logs of device usage and descriptions of the type of content accessed are needed to determine the extent to which these activities have negative (or

2017-01-01

China's energy prices have long been regulated due to the critical role energy plays in economic growth and social development, which leads to energy-price distortion to some extent. To figure out whether energy-price regulations will benefit China's economy (measured by GDP growth) and environment (measured by carbon emissions), we conducted an in-depth simulation using path analysis, where five energy products (natural gas, gasoline, fuel oil, steam coal, and coking coal) are selected and three measurements (absolute, relative, and moving) of energy-price distortions are calculated. The results indicate that, with a series of energy pricing policies, the price distortion for a single type of energy has gradually transformed, while the energy pricing system in China is not fully market-oriented yet. Furthermore, China's economy benefits from relative and moving distortions, while the absolute distortions of energy prices have negative impacts on economic growth. Finally, with regard to the environment, carbon emissions call for fewer distortions. - Highlights: • Price distortion for a single type of energy has gradually transformed. • Energy pricing system in China is not yet fully market-oriented. • China's economy benefits from relative and moving distortions. • Absolute distortions of energy prices have negative effects on economic growth. • Carbon emissions call for less pricing distortions.

Strategies to promote the reduction and cessation of injection drug use are central to human immunodeficiency virus prevention and treatment efforts globally. Though drug use cessation is a major focus of drug policy in Thailand, little is known about factors associated with injection cessation and relapse in this setting. A cross-sectional study was conducted between July and October 2011 of a community-recruited sample of people who inject drugs in Bangkok, Thailand. Using multivariate logistic regression, we examined the prevalence and correlates of injection drug use cessation with subsequent relapse. Among 422 participants, 209 (49.5%) reported a period of injection drug use cessation of at least one year. In multivariate analyses, incarceration (adjusted odds ratio [AOR] 13.07), voluntary drug treatment (AOR 2.75), midazolam injection (AOR 2.48) and number of years since first injection (AOR 1.07) were positively associated with injection cessation of duration greater than a year (all P Thailand. © 2014 Australasian Professional Society on Alcohol and other Drugs.

Full Text Available Rapid easy-to-use HIV tests offer opportunities to increase HIV testing among populations at risk of infection. We used the OraQuick Rapid HIV-1/2 antibody test (OraQuick in the Bangkok Tenofovir Study, an HIV pre-exposure prophylaxis trial among people who inject drugs.The Bangkok Tenofovir Study was a randomized, double-blind, placebo-controlled trial. We tested participants' oral fluid for HIV using OraQuick monthly and blood using a nucleic-acid amplification test (NAAT every 3 months. We used Kaplan-Meier methods to estimate the duration from a positive HIV NAAT until the mid-point between the last non-reactive and first reactive oral fluid test and proportional hazards to examine factors associated with the time until the test was reactive.We screened 3678 people for HIV using OraQuick. Among 447 with reactive results, 436 (97.5% were confirmed HIV-infected, 10 (2.2% HIV-uninfected, and one (0.2% had indeterminate results. Two participants with non-reactive OraQuick results were, in fact, HIV-infected at screening yielding 99.5% sensitivity, 99.7% specificity, a 97.8% positive predictive value, and a 99.9% negative predictive value. Participants receiving tenofovir took longer to develop a reactive OraQuick (191.8 days than participants receiving placebo (16.8 days (p = 0.02 and participants infected with HIV CRF01_AE developed a reactive OraQuick earlier than participants infected with other subtypes (p = 0.04.The oral fluid HIV test performed well at screening, suggesting it can be used when rapid results and non-invasive tools are preferred. However, participants receiving tenofovir took longer to develop a reactive oral fluid test result than those receiving placebo. Thus, among people using pre-exposure prophylaxis, a blood-based HIV test may be an appropriate choice.ClinicalTrials.gov NCT00119106.

Full Text Available Urban expansion is considered as one of the most important problems in several developing countries. Bangkok Metropolitan Region (BMR is the urbanized and agglomerated area of Bangkok Metropolis (BM and its vicinity, which confronts the expansion problem from the center of the city. Landsat images of 1988, 1993, 1998, 2003, 2008, and 2011 were used to detect the land use and land cover (LULC changes. The demographic and economic data together with corresponding maps were used to determine the driving factors for land conversions. This study applied Cellular Automata-Markov Chain (CA-MC and Multi-Layer Perceptron-Markov Chain (MLP-MC to model LULC and urban expansions. The performance of the CA-MC and MLP-MC yielded more than 90% overall accuracy to predict the LULC, especially the MLP-MC method. Further, the annual population and economic growth rates were considered to produce the land demand for the LULC in 2014 and 2035 using the statistical extrapolation and system dynamics (SD. It was evident that the simulated map in 2014 resulting from the SD yielded the highest accuracy. Therefore, this study applied the SD method to generate the land demand for simulating LULC in 2035. The outcome showed that urban occupied the land around a half of the BMR.

This publication presents a compilation of VTT's recent research on energy and eco-efficient built environment. Sustainability as a dominating driver of technology development can also be seen in the R and D portfolio of VTT Technical Research Centre of Finland. A clear focus of our research for the building sector is sustainable construction, particularly the energy efficiency of the built environment. Buildings and the whole built environment are in a key role when societies are mitigating climate change and adapting to its consequences. Despite the temporary economic downturn, construction globally remains one of the most significant areas of human activities globally. Due to the urgency of measures related to climate change and the need to provide a proper environment for living and working, a large number of national and international measures have been agreed to guarantee the future development of sustainable built environment for all. Indirectly, this has lead to a need to develop existing and completely new technologies and processes for the built environment with a speed faster than ever and with a more holistic performance metrics than ever.

Atomic energy, environment and energy conservation in Eastern Europe

Kanno, Koko

1990-01-01

About 12 % of generated electric power is the nuclear power in Eastern European countries. Generally electric power is short in these countries, and as the countermeasures for environment, the promotion of nuclear power generation is considered. However, the public opinion opposing it is also strong. The situation in respective countries is briefly discussed. The prevention of warming of the earth and the reduction of carbon dioxide gas release are the largest environmental problems discussed in western countries, but in Eastern European countries, the far more primitive problem of the damage due to SO 2 is serious. Notwithstanding high sulfur brown coal is the main fuel, the installation of desulfurizing facilities has been neglected. The demand for the countermeasures to environmental pollution by people has become strong. The energy efficiency in Eastern European countries is poor, and it is one of the causes of environmental pollution. The industrial structure is centering around heavy industries which consume much energy, the energy loss arises due to the delay of equipment modernization, and the energy is cheap, so its saving is neglected. Energy conservation is important. (K.I.)

1995-11-01

A phaseout of nuclear power in Sweden is supposed to be accomplished by year 2010. This study is an economic analysis of the questions that are parts of the nuclear dilemma. Even though the economic questions are in focus, the important environmental, health and safety questions are also treated. The basic argument is that Sweden should choose an energy system that allows its citizens to maximize their consumption in a long-term perspective. Consumption is here given a meaning that includes elements outside the market, such as environmental, health and safety aspects valued in a reasonable way. Considerations must also be given to international aspects like global environment, a free and open system of trade and the value of a stable set of rules and proprietary rights. The study compares the economic pros and cons of different energy systems within this general frame. A detailed model of the Swedish energy and power sectors was developed for the study, called the Swedish Energy and Environment Policy (SEEP) model. the SEEP model is built on modern economic theory and includes energy and environmental factors in a uniform way. 8 figs 16 tabs

As the size and complexity of high energy experiments increase there will be a greater need for better software tools and new programming environments. If these are not commercially available, then we must build them ourselves. This paper describes a prototype programming environment featuring a new type of file system, a ''smart'' editor, and integrated file management tools. This environment was constructed under the IBM VM/SP operating system. It uses the system interpreter, the system editor and the NOMAD2 relational database management system to create a software ''shell'' for the programmer. Some extensions to this environment are explored. (orig.)

Energy-environment scenarios for Senegal

Lazarus, M. [Stockholm Environment Inst. Boston, MA (United States); Diallo, S.; Sokona, Y. [Environment and Development in the Third World, Dakar (Senegal)

1994-06-01

This paper explores the energy and environmental dimensions of proposed energy strategies for Senegal. We do so using a quantitative analytical framework, and begin to explore how useful such numerical methods can be in an African context. Based on past studies and the environmental database system, we develop a set of emission factors for use in Senegal. Finally, we address ways to integrate the often unquantifiable environmental and economics cost and benefits for environmentally informed decision making. In summary, we find that polices intended to promote the substitution of liquid petroleum gas (LPG) for charcoal in households can actually reduce greenhouse gas emissions while contributing to the improvement of more important near-term environmental problems. At the same time, the impacts of LPG substitution on increasing the oil import bill is relatively small when compared to other petroleum product usage.Improving end-use energy efficiency also shows promise, suggesting that new demand-side initiatives are needed. Overall, the integrated energy-environment scenario approach can reveal combined policy impacts that might otherwise be missed in a single project or policy approach. 13 figs, 5 tabs

Childhood obesity has become a major public health issue today. The prevalence of obesity and overweight is increasing in both adult and children. Childhood obesity in Thailand has more than doubled since the 1960s and a recent study reported that overweight and obesity in Thai is the 5th highest in Asia. The present study objective is to evaluate the effectiveness of a life skills multicomponent school-based intervention on children's nutritional status. Methods: A quasi-experimental design was conducted in two-groups (control and intervention schools) on 453 students attending grade levels 4-5 in Bangkok. Two schools were selected for control, and two schools for intervention groups. The intervention included education, dietary, physical activity, food-environment, school built-environment, and life skills components. Outcomes were measured at baseline and post-treatment measured after 6 months. Results: The intervention group had significant improvements in healthier practice (+1.5 mean difference, p=0.048) on dietary habits and physical activity, lowered cholesterol levels (-2.43 mean, p=0.019), and higher HDL levels (+4.06 p=0.028) as compared to control. A higher reduction of overweight individuals among the intervention group over the intervention period was observed. Physical activity and consumption of vegetable increased while consumption of high-caloric snacks and fasts food decreased in children after the intervention. Conclusion: Childhood overweight and obesity is a serious public health problem based on its increasing rates and the associated health risks. This study indicated that multidisciplinary approach on school-based interventions is likely most effective to prevent children becoming overweight in long term. More research should be conducted on school-based intervention with longer intervention periods with higher sustainability. (author)

Role of nuclear produced hydrogen for global environment and energy

Sustainability on economical growth, energy supply and environment are major issues for the 21. century. Within this context, one of the promising concepts is the possibility of nuclear-produced hydrogen. In this study, the effect of nuclear-produced hydrogen on the environment is discussed, based on the output of the computer code 'Grape', which simulates the effects of the energy, environment and economy in 21. century. Five cases are assumed in this study. The first case is 'Business as usual by Internal Combustion Engine (ICE)', the second 'CO 2 limited to 550 ppm by ICE', the third 'CO 2 limited to 550 ppm by Hybrid Car', the fourth 'CO 2 limited to 550 ppm by Fuel Cell Vehicle (FCV) with Hydrogen produced by conventional Steam Methane Reforming (SMR)' and the fifth 'CO 2 limited to 550 ppm by FCV with Nuclear Produced-Hydrogen'. The energy used for transportation is at present about 25% of the total energy consumption in the world and is expected to be the same in the future, if there is no improvement of energy efficiency for transportation. On this point, the hybrid car shows the much better efficiency, about 2 times better than traditional internal combustion engines. Fuel Cell powered Vehicles are expected to be a key to resolving the combined issue of the environment and energy in this century. The nuclear-produced hydrogen is a better solution than conventional hydrogen production method using steam methane reforming. (author)

Systems approach to regional energy/environment management

Energy and environmental systems have become a well-established component of national and regional planning and management. The University of Wisconsin, in collaboration with the International Institute for Applied Systems Analysis and other institutions, has over the past several years conducted a number of case studies in which a family of energy/environment models was developed and applied to the assessment of alternative policies. This linked set of models, which treats energy demand, energy supply, and environmental impacts, has provided long-term planning information to a spectrum of public and private institution in the regions studied. The philosophy has been to maintain the flexibility to handle rapid change with innovation. 17 references, 7 figures, 1 table.

Energy and environment: A political ecology of woodfuels in Senegal

Science.gov (United States)

Pires, E. Mark

This study examines relationships between energy use and the exploitation of woodland natural resources in the West African nation of Senegal. As in many other countries in the developing world, the majority of the population in Senegal depend on woodfuels, i.e., firewood and charcoal, to satisfy most of their household energy needs. Consequences of this situation include added pressure on the country's limited natural resource base, and increased socioeconomic hardship, particularly for women, as woodfuel resources become increasingly scarce. Woodfuel energy problems in developing countries are typically described in terms of an imbalance between supply and demand that is driven by rapid population growth. However, recent research suggests that a number of other factors should be explored in order to achieve a more thorough understanding of the relationship between woodfuel energy and forest resource management. This study attempts to determine what some of these factors are, and to explain how they inform the energy-environment situation in the case of Senegal. In addition, I examine the scope for addressing Senegal's woodfuel problem through greater local community participation in managing energy and natural resources, a current thrust in many international initiatives designed to help the country cope with this persistent problem. A relatively new conceptual framework for the analysis of human-environment relationships---viz. political ecology---is employed in this study. I attempt to show how political ecology can contribute to the resolution of Senegal's energy-environment dilemma by considering a more inclusive suite of social, economic, political, and environmental variables than has been explored by previous approaches. Findings from the research demonstrate the ability of the political ecology approach to capture many heretofore unexplored factors related to the energy-environment nexus in Senegal. A detailed matrix is generated that illustrates the

The CE (Center for Energy conservation) has developed an energy policy plan based on energy conservation (families and industries), total energy systems, intensivation of non fossil energy sources like wind power, solar energy, biogas, geothermal energy and non use of nuclear energy in the Netherlands (CE-scenario). This energy plan is compared with the Netherlands Energy Plan developed for the Broad Public Discussion and meant as unchanged policy (Reference-scenario) and an energy policy plan based on a somewhat different energy plan with a somewhat lower aggregation level based on the same starting points. A summary is given of the data of the Reference-scenario, the basic projection and the CE-scenario. Among others the data refer to the Netherlands' energy consumption in million ton oil equivalents MTOE, welfare, unemployment and environment indicators. As environment indicators are summed up sulfur dioxide, nitrogen oxides and radioactive waste.

Venetsanos, K.; Angelopoulou, P.; Tsoutsos, T.

2002-01-01

There are four elements, which contribute to the oncoming increase of electricity demand: climate changes, the expected growth rates of EU Member State economies, changes in the consumption patterns and the introduction of new technologies. The new deregulated Electricity Market is expected to respond to this challenge and the energy supply will be adequate and cost effective within this new environment which offers promising opportunities for power producers both existing and newcomers. In this paper a framework for the appraisal of power projects under uncertainty within a competitive market environment is identified, focusing on the electricity from Renewable Energy Sources. To this end the wind energy-to-electricity, production in Greece will serve as a case study. The subject matter is centred on the following areas: the uncertainties within the new deregulated energy market; the evaluation methods including an analysis of the introduced uncertainties after deregulation and a new approach to project evaluation using the real options, as well as comparison of the valuation methodologies within the new environment drawing from the case for Greece.

Full Text Available Abstract Background Drug policy in Thailand has relied heavily on law enforcement-based approaches. Qualitative reports indicate that police in Thailand have resorted to planting drugs on suspected drug users to extort money or provide grounds for arrest. The present study sought to describe the prevalence and factors associated with this form of evidence planting by police among injection drug users (IDU in Bangkok. Methods Multivariate logistic regression was used to identify factors associated with evidence planting of drugs by police among a community-based sample of IDU in Bangkok. We also examined the prevalence and average amount of money paid by IDU to police in order to avoid arrest. Results 252 IDU were recruited between July and August, 2008, among whom 66 (26.2% were female and the median age was 36.5 years. In total, 122 (48.4% participants reported having drugs planted on them by police. In multivariate analyses, this form of evidence planting was positively associated with midazolam use (Adjusted Odds Ratio [AOR] = 2.84; 95% Confidence Interval [CI]: 1.58 - 5.11, recent non-fatal overdose (AOR = 2.56; 95%CI: 1.40 - 4.66, syringe lending (AOR = 2.08; 95%CI: 1.19 - 3.66, and forced drug treatment (AOR = 1.88; 95%CI: 1.05 - 3.36. Among those who reported having drugs planted on them, 59 (48.3% paid police a bribe in order to avoid arrest. Conclusion A high proportion of community-recruited IDU participating in this study reported having drugs planted on them by police. Drug planting was found to be associated with numerous risk factors including syringe sharing and participation in government-run drug treatment programs. Immediate action should be taken to address this form of abuse of power reportedly used by police.

Violation of a child's right to protection is an issue for children all over the world. In Thailand, the greatest barrier to intervening in child abuse issues is the lack of awareness and the positive attitudes and beliefs on using violence as a way to discipline children. The incongruent definition used amongst Thai society and relevant sectors, causes incidences to be under reported and an obstacle to child survival and development. The present study is a qualitative study and aims to explore the perceptions of child abuse and child discipline definitions amongst parents in the Bangkok Metropolitan Area in order to extend broader knowledge for interpretation, definitions and to differentiate the line between child abuse and child discipline. Focus group discussions were used as the primary data collection method and content analysis was applied as the data analysis. The results produced two categories of parents' perceptions regarding child abuse and discipline. First, was the perception of the causes of child punishment and child discipline, and second was the meaning and difference between child abuse and child discipline. The study results would be beneficial for policy makers, health and related sectors to understand the meaning of the terms used amongst family members in order to apply and promote child protection strategies in culturally appropriate

Hematocrit levels as cardiovascular risk among taxi drivers in Bangkok, Thailand

Science.gov (United States)

ISHIMARU, Tomohiro; ARPHORN, Sara; JIRAPONGSUWAN, Ann

2016-01-01

In Thailand, taxi drivers employed in the informal sector often experience hazardous working conditions. Previous studies revealed that elevated Hematocrit (HCT) is a predictor of cardiovascular disease (CVD) risk. This study assessed factors associated with HCT in taxi drivers to predict their occupational CVD risk factors. A cross-sectional study was conducted on 298 male taxi drivers who joined a health check-up campaign in Bangkok, Thailand. HCT and body mass index were retrieved from participant health check-up files. Self-administered questionnaires assessed demographics, driving mileage, working hours, and lifestyle. Statistical associations were analyzed using stepwise linear regression. Our results showed that obesity (p=0.007), daily alcohol drinking (p=0.003), and current or past smoking (p=0.016) were associated with higher HCT levels. While working hours were not directly associated with HCT levels in the current study, the effect on overworking is statistically arguable because most participants worked substantially longer hours. Our findings suggest that taxi drivers’ CVD risk may be increased by their unhealthy work styles. Initiatives to improve general working conditions for taxi drivers should take into account health promotion and CVD prevention. The policy of providing periodic health check-ups is important to make workers in the informal sector aware of their health status. PMID:27151439

Fang, Chin-Yi; Hu, Jin-Li; Lou, Tze-Kai

2013-01-01

This study computes the pure technical efficiency (PTE) and energy-saving target of Taiwan's service sectors during 2001–2008 by using the input-oriented data envelopment analysis (DEA) approach with the assumption of a variable returns-to-scale (VRS) situation. This paper further investigates the effects of industry characteristics on the energy-saving target by applying the four-stage DEA proposed by Fried et al. (1999). We also calculate the pre-adjusted and environment-adjusted total-factor energy efficiency (TFEE) scores in these service sectors. There are three inputs (labor, capital stock, and energy consumption) and a single output (real GDP) in the DEA model. The most energy efficient service sector is finance, insurance and real estate, which has an average TFEE of 0.994 and an environment-adjusted TFEE (EATFEE) of 0.807. The study utilizes the panel-data, random-effects Tobit regression model with the energy-saving target (EST) as the dependent variable. Those service industries with a larger GDP output have greater excess use of energy. The capital–labor ratio has a significantly positive effect while the time trend variable has a significantly negative impact on the EST, suggesting that future new capital investment should also be accompanied with energy-saving technology in the service sectors. - Highlights: • The technical efficiency and energy-saving target of service sectors are assessed. • The pre-adjusted and environment-adjusted total-factor energy efficiency scores in services are assessed. • The industrial characteristic differences are examined by the panel-data, random-effects Tobit regression model. • Labor, capital, and energy and an output (GDP) are included in the DEA model. • Future new capital investment should also be accompanied with energy-saving technology in the service sectors

Energy use and the resulting environmental impacts are major points of concern for the world in the 21st century. Opinions that define the challenges of sustainable energy options are as diverse as the proposed solutions. The industrial sector is a key area both from the standpoint of the amount of energy consumed and the magnitude of the energy options that exist there. However, history has shown that success in the industrial energy sector requires careful planning and consideration of the unique challenges of the manufacturing environment.

Energy, entropy, environment: Why is protection of the environment objectively difficult?

Energy Technology Data Exchange (ETDEWEB)

Rebane, Karl K [Institute of Physics, Tartu (Estonia)

1995-05-01

Evolution and man`s history indicate that the winners are the species and societies that act faster and consume more high-quality energy and materials: in other words, those which cause more pollution and faster growth of entropy. This could be the reason why protection of the environment is objectively difficult and, in particular, why it is almost impossible to considerably reduce man`s consumption of energy and materials in a world of competition. To escape this fatal evolutionary outcome, fundamentally new thinking is needed, thinking which takes the survival of mankind as the primary value. The role of religion in solving this tremendously difficult task should not be neglected

The elements and structure of a small-scale regional energy-environment game are presented, with special emphasis on the definition of appropriate actors and state variables as well as characterization of the target region for which the game is designed. The results of this Phase I game will be used to aid the design of components in a more comprehensive game (Phase II) that can be used for investigating various energy-environment scenarios in a regional assessment study program. The principal results that will be used in the Phase II effort are: (1) definition of the target region; (2) development of reference scenarios describing energy-environment trends and mechanisms within the target region; (3) characterization of principal actors involved in the regional energy - environment system; and (4) definition of a set of factors or state variables that reflect the state of that system.

2017-12-01

Full Text Available Energy efficiency is a significant characteristic of battery-run devices such as sensors, RFID and mobile phones. In the present scenario, this is the most prominent requirement that must be served while introducing a communication protocol for an IoT environment. IoT network success and performance enhancement depend heavily on optimization of energy consumption that enhance the lifetime of IoT nodes and the network. In this context, this paper presents a comprehensive review on energy efficiency techniques used in IoT environments. The techniques proposed by researchers have been categorized based on five different layers of the energy architecture of IoT. These five layers are named as sensing, local processing and storage, network/communication, cloud processing and storage, and application. Specifically, the significance of energy efficiency in IoT environments is highlighted. A taxonomy is presented for the classification of related literature on energy efficient techniques in IoT environments. Following the taxonomy, a critical review of literature is performed focusing on major functional models, strengths and weaknesses. Open research challenges related to energy efficiency in IoT are identified as future research directions in the area. The survey should benefit IoT industry practitioners and researchers, in terms of augmenting the understanding of energy efficiency and its IoT-related trends and issues.

Hydrodynamic modelling and global datasets: Flow connectivity and SRTM data, a Bangkok case study.

Trigg, M. A.; Bates, P. B.; Michaelides, K.

The rise in the global interconnected manufacturing supply chains requires an understanding and consistent quantification of flood risk at a global scale. Flood risk is often better quantified (or at least more precisely defined) in regions where there has been an investment in comprehensive topographical data collection such as LiDAR coupled with detailed hydrodynamic modelling. Yet in regions where these data and modelling are unavailable, the implications of flooding and the knock on effects for global industries can be dramatic, as evidenced by the recent floods in Bangkok, Thailand. There is a growing momentum in terms of global modelling initiatives to address this lack of a consistent understanding of flood risk and they will rely heavily on the application of available global datasets relevant to hydrodynamic modelling, such as Shuttle Radar Topography Mission (SRTM) data and its derivatives. These global datasets bring opportunities to apply consistent methodologies on an automated basis in all regions, while the use of coarser scale datasets also brings many challenges such as sub-grid process representation and downscaled hydrology data from global climate models. There are significant opportunities for hydrological science in helping define new, realistic and physically based methodologies that can be applied globally as well as the possibility of gaining new insights into flood risk through analysis of the many large datasets that will be derived from this work. We use Bangkok as a case study to explore some of the issues related to using these available global datasets for hydrodynamic modelling, with particular focus on using SRTM data to represent topography. Research has shown that flow connectivity on the floodplain is an important component in the dynamics of flood flows on to and off the floodplain, and indeed within different areas of the floodplain. A lack of representation of flow connectivity, often due to data resolution limitations, means

Optimal Energy Taxation for Environment and Efficiency

Pak, Y.D. [Korea Energy Economics Institute, Euiwang (Korea)

2001-11-01

Main purpose of this research is to investigate about how to use energy tax system to reconcile environmental protection and economic growth, and promote sustainable development with the emphasis of double dividend hypothesis. As preliminary work to attain this target, in this limited study I will investigate the specific conditions under which double dividend hypothesis can be valid, and set up the model for optimal energy taxation. The model will be used in the simulation process in the next project. As the beginning part in this research, I provide a brief review about energy taxation policies in Sweden, Netherlands, and the United States. From this review it can be asserted that European countries are more aggressive in the application of environmental taxes like energy taxes for a cleaner environment than the United States. In next part I examined the rationale for optimal environmental taxation in the first-best and the second-best setting. Then I investigated energy taxation how it can provoke various distortions in markets and be connected to the marginal environmental damages and environmental taxation. In the next chapter, I examined the environmentally motivated taxation in the point of optimal commodity taxation view. Also I identified the impacts of environmental taxation in various circumstances intensively to find out when the environment tax can yield double dividend after taking into account of even tax-interaction effects. Then it can be found that even though in general the environmental tax exacerbates the distortion in the market rather than alleviates, it can also improve the welfare and the employment under several specific circumstances which are classified as various inefficiencies in the existing tax system.

Environment-adjusted regional energy efficiency in Taiwan

This study applies the four-stage DEA procedure to calculate the energy efficiency of 23 regions in Taiwan from 1998 to 2007. After controlling for the effects of external environments, only Taipei City, Chiayi City, and Kaohsiung City are energy efficient. Note that Kaohsiung City reaches the efficiency frontier due to the adjustment via partial environmental factors such as higher education attainment and transport vehicles. We also find a worsening trend for Taiwan's energy efficiency. Not only is there a gap of energy efficiency between Taiwan's metropolitan areas and the other regions, but the gap has also widened in recent years. Those inefficient counties should be given priority and the savings potential. Except for road density, the evidence indicates that each environmental factor has partial incremental effects on input slacks. As more cars and motorcycles are unfavorable externalities affecting partial energy efficiency, the central government should help local governments retire inefficient old motor vehicles, encourage energy-saving vehicle models, and provide convenient mass transportation systems. Besides, people with higher education cause industrial energy inefficient in Taiwan. The conscious of effective energy saving is necessary to schools, communities, and employee accordingly.

Also, the characteristic eukaryotic community structure in DHS reactor was investigated. Long-term operation of a DHS reactor for direct treatment of domestic wastewater (COD = 150-170 mg/L and BOD = 60-90 mg/L) was performed under the average ambient temperature ranged from 28°C to 31°C in Bangkok, Thailand. Throughout the evaluation period of 550 days, the DHS reactor at a hydraulic retention time of 3 h showed better performance than the existing oxidation ditch process in the removal of organic carbon (COD removal rate = 80-83% and BOD removal rate = 91%), nitrogen compounds (total nitrogen removal rate = 45-51% and NH 4 + -N removal rate = 95-98%), and low excess sludge production (0.04 gTS/gCOD removed). The clone library based on the 18S ribosomal ribonucleic acid gene sequence revealed that phylogenetic diversity of 18S rRNA gene in the DHS reactor was higher than that of the present oxidation ditch process. Furthermore, the DHS reactor also demonstrated sufficient COD and NH 4 + -N removal efficiency under flow rate fluctuation conditions that simulates a small-scale treatment facility. The results show that a DHS reactor could be applied as a decentralized domestic wastewater treatment technology in tropical regions such as Bangkok, Thailand.

The energy and environment issue was considered from a viewpoint of human happiness. The paper picks up economy, philosophy, energy and humans as organisms, and considered how the principle of the increase by geometrical progression plays an important role in these. That the repetition in phenomena is like the increase by geometrical progression means that changes increase not linearly but exponentially and nonlinearly and bring such large changes as are unimaginable. The increase in entropy, which is caused by a nonlinear increase of the state, is an irreparable change. The problem of the pursuit of happiness also cannot be solved by the linear thought. The energy and environment problem cannot reach the solution in an extension of the linear thought in which humans have overcome poverty and lacks since the past and pursued richness earnestly. Namely, it is necessary for the 21st century to stop thinking of the energy utilization for seeking for much more richness and to try to think the energy issue in the social system where happiness with not too much richness is presupposed. 16 refs., 1 fig., 1 tab.

Energy efficiency improvement and environment in China

International Nuclear Information System (INIS)

Rouhier, Stephane

2010-01-01

Massive reliance on polluting sources of energy (coal, traditional biomass and oil) has damaged the environment in China over years. Now, China is the world's first carbon dioxide emitter and air pollution represents between 2 and 7 percent of loss of Gross Domestic Product per year, depending on the studies chosen. In order to reduce the level of pollution, one can either enhance the technology in use or reduce the share of polluting fuels in the energy mix. Indeed, current Chinese technologies are far less efficient than those of developed countries and the energy mix is massively composed of polluting sources of energy. So, they both represent huge potential savings. This article enquires the link between diversification, efficiency in the power sector and the per capita emissions and shows that emissions are negatively correlated to a diversification of the energy mix as well as an improvement of power generating technologies. Hence, it justifies the diversification of the energy mix and technology improvement as viable strategies to tackle pollution

While energy links all living and non-living systems, the integration of energy, the environment, and society is often not clearly represented in 9 - 12 classrooms and informal learning venues. However, objective public learning that integrates these components is essential for improving public environmental literacy. ENERGY-NET (Energy, Environment and Society Learning Network) is a National Science Foundation funded initiative that uses an Earth Systems Science framework to guide experimental learning for high school students and to improve public learning opportunities regarding the energy-environment-society nexus in a Museum setting. One of the primary objectives of the ENERGY-NET project is to develop a rich set of experimental learning activities that are presented as exhibits at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania (USA). Here we detail the evolution of the ENERGY-NET exhibit building process and the subsequent evolution of exhibit content over the past three years. While preliminary plans included the development of five "exploration stations" (i.e., traveling activity carts) per calendar year, the opportunity arose to create a single, larger topical exhibit per semester, which was assumed to have a greater impact on museum visitors. Evaluative assessments conducted to date reveal important practices to be incorporated into ongoing exhibit development: 1) Undergraduate mentors and teen exhibit developers should receive additional content training to allow richer exhibit materials. 2) The development process should be distributed over as long a time period as possible and emphasize iteration. This project can serve as a model for other collaborations between geoscience departments and museums. In particular, these practices may streamline development of public presentations and increase the effectiveness of experimental learning activities.

The Center for Energy Education (CEE) is a partnership linking the University of Oklahoma, Close Up Foundation and Department of Energy. Based upon the theme of energy, environment and public policy, the CEE`s main purposes are to: (1) educate teachers on energy sources, environmental issues and decisionmaking choices regarding public policy; (2) develop interdisciplinary curricula that are interactive in nature (see attachments); (3) disseminate energy education curricula; (4) serve as a resource center for a wide variety of energy education materials; (5) provide a national support system for teachers in energy education; and (6) conduct research in energy education. The CEE conducted its first two-week experimentially-based program for educators during the summer of 1993. Beginning at the University of Oklahoma, 57 teachers from across the country examined concepts and issues related to energy and environment, and how the interdependence of energy and environment significantly influences daily life. During the second week of the institute, participants went to Washington, D.C. to examine the processes used by government officials to make critical decisions involving interrelationships among energy, environment and public policy. Similar institutes were conducted during the summers of 1994 and 1995 resulting in nearly 160 science and social studies educators who had participated in the CEE programs. Collectively the participants represented 36 states, the Pacific Territories, Puerto Rico, and Japan.

The effective environmental protection begins when saving. Energy which is not used at all also cannot burden the environment. Pleasant side effect: also the purse is treated gently. One of the most important measures for the reduction of energy consumption is the correct thermal insulation of a building so that heating energy cannot escape unused in the free. Thus, between 50 and 75 per cent of energy can be saved. Investments within this range usually are profitable already after a short time. The utilization of damming materials from regenerative raw materials enables application of financial incentives. In addition, within other ranges of the house modernizations and a change of the behaviour of utilization help to save energy. The contribution under consideration gives advices in order to improve dwellings energy-technically. The environment and the purse will thank it.

Energy efficiency in the built environment can make significant contributions to a sustainable energy economy. In order to achieve this, greater public awareness of the importance of energy efficiency is required. In the short term, new efficient domestic appliances, building technologies, legislation quantifying building plant performance, and improved building regulations to include installed plant will be required. Continuing these improvements in the longer term is likely to see the adoption of small-scale renewable technologies embedded in the building fabric. Internet-based energy services could deliver low-cost building energy management and control to the mass market enabling plant to be operated and maintained at optimum performance levels and energy savings quantified. There are many technology options for improved energy performance of the building fabric and energy systems and it is not yet clear which will prove to be the most economic. Therefore, flexibility is needed in legislation and energy-efficiency initiatives

Ruetschi, Paul

Batteries can store energy in a clean, convenient and efficient manner. Battery-powered electric vehicles are expected to contribute to a cleaner environment. In today's world, batteries are used everywhere: in electronic watches, pocket calculators, flashlights, toys, radios, tape recorders, cameras, camcorders, laptop computers, cordless telephones, paging devices, hearing aids, heart pacers, instruments, detectors, sensors, memory back-up devices, drug dispensing, wireless tools, toothbrushes, razors, stationary emergency power equipment, automobile starters, electric vehicles, boats, submarines, airplanes and satellites. Worldwide, about 15 billion primary batteries, and well over 200 million starter batteries are produced per year. What is the impact of this widespread use of batteries on the environment? What role can battery technology play in order to reduce undue effects on the environment? Since this paper is presented at a lead/acid battery conference, the discussion refers, in particular, to this system. The following aspects are covered: (i) the three "E" criteria that are applicable to batteries: Energy, Economics, Environment; (ii) service life and environment; (iii) judicious use and service life; (iv) recycling.

Full Text Available Abstract Background Although previous studies have identified high levels of drug-related harm in Thailand, little is known about illicit drug overdose experiences among Thai drug users. We sought to investigate non-fatal overdose experiences and responses to overdose among a community-recruited sample of injection drug users (IDU in Bangkok, Thailand. Methods Data for these analyses came from IDU participating in the Mit Sampan Community Research Project. The primary outcome of interest was a self-reported history of non-fatal overdose. We calculated the prevalence of past overdose and estimated its relationship with individual, drug-using, social, and structural factors using multivariate logistic regression. We also assessed the prevalence of ever witnessing an overdose and patterns of response to overdose. Results These analyses included 252 individuals; their median age was 36.5 years (IQR: 29.0 - 44.0 and 66 (26.2% were female. A history of non-fatal overdose was reported by 75 (29.8% participants. In a multivariate model, reporting a history of overdose was independently associated with a history of incarceration (Adjusted Odds Ratio [AOR] = 3.83, 95% Confidence Interval [CI]: 1.52 - 9.65, p = 0.004 and reporting use of drugs in combination (AOR = 2.48, 95% CI: 1.16 - 5.33, p = 0.019. A majority (67.9% reported a history of witnessing an overdose; most reported responding to the most recent overdose using first aid (79.5%. Conclusions Experiencing and witnessing an overdose were common in this sample of Thai IDU. These findings support the need for increased provision of evidence-based responses to overdose including peer-based overdose interventions.

The development and utilization of biomass energy can help to change the ways of energy production and consumption and establish a sustainable energy system that can effectively promote the development of the national economy and strengthen the protection of the environment. Here,we perform a bibliometric analysis of 9514 literature reports in the Web of Science Core Collection searched with the key words "Biomass energy" and "Environment*" date from 1998 to 2017; hot topics in the research and development of biomass energy utilization, as well as the status and development trends of biomass energy utilization and the environment, were analyzed based on content analysis and bibliometrics. The interaction between biomass energy and the environment began to become a major concern as the research progressively deepened. This work is of great significance for the development and utilization of biomass energy to put forward specific suggestions and strategies based on the analysis and demonstration of relationships and interactions between biomass energy utilization and environment. It is also useful to researchers for selecting the future research topics. Copyright © 2018 Elsevier B.V. All rights reserved.

Energy and the environment. A global view and strategies

International Nuclear Information System (INIS)

Pasztor, J.

1988-01-01

It should be recognized that the key to the future is in the rational use of energy, that is, a more efficient use of energy rather than a continuous increase in the supply of energy. Every unit of energy saved is a unit of energy which does not have to be produced, and whose environmental impacts do not have to be dealt with. Massive reductions in the growth rates, and, where possible, in the absolute use of energy will help us to gain time to better understand and develop response strategies to problems like climate change on the acidification of the environment. In this sense the rational use of energy, including intensified energy efficiency measures is the most environmentally sound energy option with which we should move into the next century. 25 refs., 4 figs

Dementia is a significant issue globally, including in Thailand, and exercise is known to have health benefits for people living with dementia. However, little is known about exercise acceptable to, and feasible for, this population group in low-to-middle income countries although, more broadly, it is recognised that health-related behaviours are influenced by the perceptions of the individual, which exist within a cultural context. To explore and describe perceptions of appropriate exercise for people living with dementia in Bangkok, Thailand. Qualitative exploratory descriptive. Bangkok, Thailand. Nine professionals - experts in exercise, dementia care and relevant policy development - and nine dyads of people with dementia and their family caregivers all recruited using purposive sampling. Semi-structured interviews subjected to thematic analysis. Three themes emerged: how exercise was defined, perceived benefits of exercise and how exercise should be implemented. Professionals recognised three exercise elements: aerobic exercise plus balance and strength training. Dyads recognised home-based activities (e.g., housework) and walking. Both groups recognised benefits of exercise in maintaining health and function and improving mood and sleep. Only health professionals identified falls risk reduction. There was limited appreciation of benefits for caregivers by maintaining function in care recipients. Professionals deemed that exercise should address all three elements, using easily accessible low-cost resources. The need for safety was emphasised, and there was agreement that in-home exercise was appropriate. Family/cultural values were evident that could present barriers to exercise implementation. Changing health-related behaviours requires an understanding of individual perspectives, which exist within a cultural context. This study has illuminated the Thai context and has implications beyond this. Findings emphasise a need for potential benefits to be

Full Text Available En Thaïlande, les ensembles d’habitat spontané s’étendent à toute la capitale, malgré des politiques publiques qui visent à les contrer. Ce sont aujourd’hui de véritables morceaux de ville qui dynamisent l’espace urbain, car étroitement liés à l’identité et à l’histoire de la ville. L’opposition entre habitat spontané et « logement formel », fréquente tant dans les productions scientifiques que dans les représentations, mérite donc d���être interrogée à Bangkok. À partir d’une analyse spatiale et architecturale, nous avons abordé l’habitat spontané comme une manière de fabriquer la ville centrée sur l’appropriation : au moins sous trois formes (habitat spontané pur, ancien, greffé, il assure par sa flexibilité la continuité du tissu urbain et s’y assimile progressivement. Si pour les autorités locales les communautés de bidonvilles demeurent un signe de sous-développement, certains architectes et acteurs y voient une source d’inspiration ainsi qu’un patrimoine populaire à préserver.

Roeser, D

2012-06-15

Ambitious international efforts to combat climate change have lead to a large interest about the use of forest biomass for energy in many countries. In order to meet the expected growing demand in the future, it will be necessary to improve operational efficiency of existing forest energy supply chains and support the establishment of efficient supply chains in new operational environments. The thesis applied a three-dimensional approach which examines forest energy supply chains from a technical, social and economic viewpoint. Four case studies in different operational environments have been carried out to investigate the applicability of the three dimensional approach to improve operational efficiency. The technical dimension was investigated in Paper 1 and 2. In Paper 1, the effects of climatic conditions, covering of piles, and partial debarking on drying of roundwood were studied in four experimental trials located in Scotland, Finland and Italy. In Paper 2, the chipping of forest biomass was studied in two different operational environments. The investigation of the social dimension in Paper 3 provides insights into the setup of two different supply chains through business process mapping and simulation. Finally, in paper 4, which investigated the economic dimension, an analysis of the effect of the operational environment on technology selection and design of supply chains, is presented. The thesis demonstrates that the chosen approach was practical to investigate the complex relationships between the chosen technologies and different supply chain actors and stakeholders thereby contributing to maintain or improve operational efficiency of forest energy supply chains. Due to its applicability in different operational environments, the approach is also suitable in a more global context. Furthermore, it captures the effect of different aspects and characteristics of the various operational environments on the setup and organization of supply chains. This will

The effective environmental protection begins when saving. Energy which is not used at all also cannot burden the environment. Pleasant side effect: also the purse is treated gently. One of the most important measures for the reduction of energy consumption is the correct thermal insulation of a building so that heating energy cannot escape unused in the free. Thus, between 50 and 75 per cent of energy can be saved. Investments within this range usually are profitable already after a short time. The utilization of damming materials from regenerative raw materials enables application of financial incentives. In addition, within other ranges of the house modernizations and a change of the behaviour of utilization help to save energy. The contribution under consideration gives advices in order to improve dwellings energy-technically. The environment and the purse will thank it.

Childhood obesity has become a major public health issue today. The prevalence of obesity and overweight is increasing in both adults and children. Childhood obesity in Thailand has more than doubled since the 1960s and a recent study reported that overweight and obesity in Thais is the 5th highest in Asia. The present study objective was to evaluate the effectiveness of a life-skills, multicomponent, school-based intervention on child nutritional status. A quasi-experimental design was conducted in two-groups (control and intervention schools) on 453 students attending grade levels 4-5 in Bangkok. Two schools were selected for control, and two schools for intervention groups. The interventions included education, diet, physical activity (PA), food-environment, school builtenvironment, and life-skills components. Subjects were measured at baseline and at 6 months post-treatment. The intervention group had significant differences in overall healthy practices (+1.5 mean difference, p=0.048), dietary habits, physical activity, lower total cholesterol (TC) levels (-2.43 mean, p=0.019) and higher high density lipoprotein cholesterol (HDL-C) levels (+4.06 p=0.028) as compared to the control. A higher reduction of overweight individuals among the intervention group over the intervention period was observed. Physical activity and consumption of vegetables increased while consumption of high-caloric snacks and fast foods decreased in children after the intervention. This study indicated that a multidisciplinary approach in school-based interventions is most likely to be effective in preventing children from becoming overweight in the long term. More research should be conducted on school-based interventions with longer intervention periods and higher sustainability.

Security, environment, and economic concerns are commonly identified as three major objectives of energy policy. State and federal governments have set aggressive targets for carbon emissions reductions and for alternative fuel use and increased vehicle efficiency to reduce petroleum consumption. Moreover, jobs creation and GDP growth are often cited as key drivers for energy policies. Previous studies on energy policy decision-making have examined the process for developing and evaluating options using multi-criteria decision analysis tools. In addition, energy opinion polls have either elicited preferences between two goals or whether the public supports a specific policy action. In this article, we report results from a survey of 884 members of professional membership organizations on how the U.S. should prioritize energy policy across the goals of energy supply security, environment and climate, and economics and job creation. The majority favor policymaking that is balanced across all three. Security and economic concerns increase with age for male respondents, whereas environment is the highest priority for females regardless of age. Unlike previous surveys that target the general public and focus on a particular objective or technology, these results provide an example of eliciting a portfolio allocation across multiple energy policy goals from targeted constituents. - Highlights: • We surveyed 884 members of professional membership organizations on how the U.S. should prioritize energy policy. • The paper addresses direct elicitation of energy policy goal portfolio allocation for a large set of energy stakeholders. • The majority of respondents favor policymaking balanced across multiple goals. • We observed differences in priorities based on age and gender. • Respondents expressed a tension in allocating across goals that are interrelated

As Canada debates ways to address climate change, the country's low-impact renewable energy industries want to ensure that Canadians are provided with all of the options available to them. Accordingly, they have come together to create Options for a Clean Environment and Healthy Canadian Economy. Recognizing there is no 'silver bullet' solution to climate change, this document identifies an important suite of measures that, along with others, will allow Canada to achieve its long-term economic and environmental goals. The measures described in this document represent an investment in Canada's future. If implemented, they will reduce annual greenhouse gas (GHG) emissions by more than 12 million tonnes (Mt) by the year 2010 (roughly 8% of Canada's reduction target), create thousands of new jobs, and reduce health-care costs by millions of dollars each year. The most significant dividends from these measures, however, will occur after 2010 as a result of having set in motion fundamental changes in the attitudes of Canadians and the nature of the Canadian energy market. By 2020, the spin-off actions prompted by these measures will likely have resulted in GHG reductions twice as great as those achieved in 2010. This document highlights the opportunities associated specifically with Canada's low-impact renewable energy resources. These are non-fossil-fuel resources that are replenished through the earth's natural cycles and have a minimal impact on the environment and human health. They include wind, solar, earth energy, run-of-river hydro and sustainable biomass fuels. These resources can replace fossil fuels in a variety of areas, including electricity and space and water heating. Fuel cells, although not a renewable resource in themselves, are a promising technology that in combination with renewables have the potential to deliver versatile low-impact electricity. The document also identifies opportunities associated with the increased use of passive renewable energy

Technological learning in energy-environment-economy modelling: A survey

International Nuclear Information System (INIS)

Kahouli-Brahmi, Sondes

2008-01-01

This paper aims at providing an overview and a critical analysis of the technological learning concept and its incorporation in energy-environment-economy models. A special emphasis is put on surveying and discussing, through the so-called learning curve, both studies estimating learning rates in the energy field and studies incorporating endogenous technological learning in bottom-up and top-down models. The survey of learning rate estimations gives special attention to interpreting and explaining the sources of variability of estimated rates, which is shown to be mainly inherent in R and D expenditures, the problem of omitted variable bias, the endogeneity relationship and the role of spillovers. Large-scale models survey show that, despite some methodological and computational complexity related to the non-linearity and the non-convexity associated with the learning curve incorporation, results of the numerous modelling experiments give several new insights with regard to the analysis of the prospects of specific technological options and their cost decrease potential (bottom-up models), and with regard to the analysis of strategic considerations, especially inherent in the innovation and energy diffusion process, in particular the energy sector's endogenous responses to environment policy instruments (top-down models)

2013-07-01

The aim of this study is to reveal the cognitive construction about the relationship between nuclear energy and environment of the undergraduates who have studied science of environment by using word association test and to determine the conception mistakes. The research was made on 81 trainee teachers who study at Ahmet Kelerlu Faculty of Education Department of Geography and Biology, University of Necmettin Erbakan on 2012-2013 academic year fall semester. In the study, it was seen that the topics which the undergraduates mostly refer in their written statements were the nuclear energy's indication of improvement of countries, its necessity, nuclear accidents, nuclear weapons and the ecocide. The other opinions which gained importance were nuclear reaction, nuclear raw material and countries producing nuclear energy. It's seen that nuclear accidents and nuclear weapons are very effective on the graduates' point of view. The opinions about nuclear energy's harm to the environment show that environmental awareness became of secondary importance. The written concepts about these two opinions are very close to each other by percentage. Mainly, the radiation effects caused by the nuclear accidents constitute the fundamental point of undergraduates' perception of environment. (author)

Photosynthetic Energy Storage for the Built Environment: Modeling Energy Generation and Storage for Net-Zero Analysis

Science.gov (United States)

Lichter-Marck, Eli Morris

There is a growing need to address the energy demand of the building sector with non-polluting, renewable energy sources. The Net Zero Energy Building (NZEB) mandate seeks to reduce the impact of building sector energy consumption by encouraging on-site energy generation as a way to offset building loads. However, current approaches to designing on-site generation fail to adequately match the fluctuating load schedules of the built environment. As a result, buildings produce highly variable and often-unpredictable energy import/export patterns that create stress on energy grids and increase building dependence on primary energy resources. This research investigates the potential of integrating emerging photo-electrochemical (PEC) technologies into on-site generation systems as a way to enable buildings to take a more active role in collecting, storing and deploying energy resources according to their own demand schedules. These artificially photosynthetic systems have the potential to significantly reduce variability in hour-to-hour and day-to-day building loads by introducing high-capacity solar-hydrogen into the built environment context. The Building Integrated Artificial Photosynthesis (BIAP) simulation framework presented here tests the impact of hydrogen based energy storage on NZEB performance metrics with the goal of developing a methodology that makes on-site energy generation more effective at alleviating excessive energy consumption in the building sector. In addition, as a design performance framework, the BIAP framework helps guide how material selection and scale up of device design might tie photo-electrochemical devices into parallel building systems to take full advantage of the potential outputs of photosynthetic building systems.

This paper applies the Lotka–Volterra model to investigate the competitive interactions among energy, environment, and economy (3Es) in the U.S. The proposed LV-COMSUD (Lotka–Volterra COmpetition Model for SUstainable Development) has satisfactory performance for model fitting and provides a useful multivariate framework to predict outcomes concerning these interactions. Our key findings include a pure competition between emissions and GDP (Gross Domestic Product), neutralisms between renewable and fossil/nuclear energy, and commensalisms between GDP and renewable/fossil energy and between nuclear energy and fossil energy/emissions. These results indicate that renewable/fossil energy use contributes to GDP and interacts indirectly with emissions, that an environmental Kuznets curve exists, and that the amount of produced nuclear energy correlates with emission. The U.S. is dependent on non-clean energy sources and its energy efficiency has room for improvement. The results provide unique insights for policy makers to craft up sustainable economic development plans. Overall, it is suggested that for developed markets such as the U.S., to enhance energy security and mitigate climate changes, improving energy efficiency and developing low-carbon clean energy should be top priorities. - Highlights: • The competitive interactions among energy, environment, and economy are examined. • A pure competition between emissions and GDP exists and an EKC exists. • Energy use contributes to GDP and interacts indirectly with emissions. • Nuclear energy was used to tackle the growth of emissions/fossil energy use. • Improved energy efficiency is a viable policy to enhance energy security in U.S

Despite the availability of safe and effective vaccines, little is known about prevalence and risk factors for hepatitis A (HAV) and hepatitis B virus (HBV) infection among Thai men who have sex with men. The prevalence of HAV and HBV infection among men who have sex with men cohort in Bangkok was assessed. Baseline blood specimens were drawn and demographic and behavioral data were collected. Bivariate and multivariate logistic regression analysis was used to analyze risk factors for prevalent HAV and HBV infection. One thousand two hundred ninety-nine Thai men who have sex with men 18 years and older were enrolled. Among those with results, 349/1,291 (27.0%) had evidence of past or current hepatitis A infection. Of the 1,117 (86.5%) men with unambiguous HBV test results, 442 (39.6%) had serologic evidence of past/current infection, 103 (9.2%) were immune due to hepatitis B vaccination, 572 (51.2%) had no evidence of immunological exposure to HBV or vaccine. Of those with past/current HBV infection, 130 (29.4%) were HIV positive. Age >35 years was independently associated with both HAV and HBV infection. University education was protective against both HAV and HBV infection. Increased alcohol consumption, number of lifetime male sexual partners ≥10, and prevalent HIV infection were also independently associated with HBV infection. The prevalence of past/current HAV and HBV infection was high in Bangkok men who have sex with men. Age-cohorts with a higher prevalence of hepatitis B vaccine induced immunity may be expected in the future. Hepatitis A and B vaccination is recommended. © 2013 WILEY PERIODICALS, INC.

Price Elasticity of Demand and Capacity-Restraint Transit Fare Strategy: A Case Study of Bangkok Mass Transit System

Directory of Open Access Journals (Sweden)

Ackchai Sirikijpanichkul

2015-01-01

Full Text Available Traffic congestion is a chronic problem of Bangkok. Similar to other metropolises, the city perpetually seeks for alternatives to road travel. Mass rapid transit seems to be the only way out that is expected to mitigate traffic congestion in the city. However, without common fare system, travelers need to pay an initial entrance fee every time they enter each transit system. This excess cost tapers the demand and affects the efficient use of the system. This research investigates the influence of fare price on transit use which is measured by price elasticity of demand and proposes the optimum fare price if the common fare is used. The analysis is based on the findings from the stated preference survey techniques. Finally, the conclusion on fare level that encourage more patronage, maintain service quality and operator revenue is addressed.

Lightweight Sensor Authentication Scheme for Energy Efficiency in Ubiquitous Computing Environments.

2016-12-01

The Internet of Things (IoT) is the intelligent technologies and services that mutually communicate information between humans and devices or between Internet-based devices. In IoT environments, various device information is collected from the user for intelligent technologies and services that control the devices. Recently, wireless sensor networks based on IoT environments are being used in sectors as diverse as medicine, the military, and commerce. Specifically, sensor techniques that collect relevant area data via mini-sensors after distributing smart dust in inaccessible areas like forests or military zones have been embraced as the future of information technology. IoT environments that utilize smart dust are composed of the sensor nodes that detect data using wireless sensors and transmit the detected data to middle nodes. Currently, since the sensors used in these environments are composed of mini-hardware, they have limited memory, processing power, and energy, and a variety of research that aims to make the best use of these limited resources is progressing. This paper proposes a method to utilize these resources while considering energy efficiency, and suggests lightweight mutual verification and key exchange methods based on a hash function that has no restrictions on operation quantity, velocity, and storage space. This study verifies the security and energy efficiency of this method through security analysis and function evaluation, comparing with existing approaches. The proposed method has great value in its applicability as a lightweight security technology for IoT environments.

Social science literature on the environment: review and prospects for energy studies. A preliminary literature survey

1975-01-01

Much of the social science literature on environment is of recent origin and represents the response of the social science research community to a complex societal problem in which technology is a major factor. Energy represents another such problem to which the social science research community is now turning its attention. Because energy problems and environment problems have some similarities and because energy-conversion processes have large effects on the environment, a review of the social science literature on environment was undertaken. The purposes of this review are as follows: (1) to study the possible utility in energy research of some of the concepts developed in social science research on the environment; (2) to study the possible utility in energy research of some of the methodologies utilized in social science research on the environment; and (3) to study the extent to which the results of social science research on the environment have contributed to the development of policy. The first two items above receive major attention in this preliminary literature survey. 50 references.

A first article discusses the different impacts that renewable energies may have on the environment, i.e. on the human environment (risks associated with dams, aesthetic impacts, impacts on landscapes, neighbouring nuisances) or on the natural environment (natural media, wildlife and flora). A second article outlines that the legal framework of hydroelectricity is rather old and therefore ignored (willingly or not?) environmental concerns whereas environmental impacts actually exist. Therefore, a new legal context must be defined, notably by taking into account objectives defined in the international and European Union law, in particularly the requirements related to ecological continuity

This study investigated the influence of benzene concentration from motorcycle exhaust emissions on ambient air quality in Bangkok Metropolitan Region (BMR). Measurement of benzene concentration in exhaust emissions is performed on a standard test driving cycle through which each motorcycle to be tested is driven. The test result revealed that average benzene concentrations in exhaust emission for the test motorcycles ranged from 3.02 to 109.68 mg/m 3. The finding also indicated that two-stroke motorcycles emitted five times more benzene than that of four-stroke motorcycles. Four air monitoring sites were strategically established to determine the relationship between average benzene concentrations with different traffic configurations in each traffic zone of BMR during peak/non-peak hours, day/night times and weekday/weekend. The shape of the curve for benzene level usually shows two peaks corresponding to the morning and evening traffic rush or commuter rush hours. The finding shows that the mean concentrations for benzene in all monitoring stations in the ambient air for peak hours (07:00-09:00 and 16:00-18:00 h) ranged from 15.1 to 42.4 μg/m 3. For non-peak hour (11:30-15:00 h), benzene levels were found in the range 16.3-30.9 μg/m 3. It is observed that higher levels of benzene are found among roadside stations with slow moving traffic while lower levels are found among roadside stations with fast traffic movement. Additional factors such as temperature, wind speed, rainfall, etc. are also considered in this study to determine the relationship between traffic conditions and ambient benzene levels.

Full Text Available In this paper, we propose a new HVAC (heating, ventilation, and air conditioning control strategy as part of the smart energy system that can balance occupant comfort against building energy consumption using ubiquitous sensing and machine learning technology. We have developed ZigBee-based wireless sensor nodes and collected realistic temperature and humidity data during one month from a laboratory environment. With the collected data, we have established a building environment model using machine learning algorithms, which can be used to assess occupant comfort level. We expect the proposed HVAC control strategy will be able to provide occupants with a consistently comfortable working or home environment.

Conn, Cath; Modderman, Kristel; Nayar, Shoba

Participation is an accepted means of increasing the effectiveness of public health programs, and as such, it is considered an important component of HIV interventions targeting at-risk youth. The situation of young women sex workers in Thailand is alarming on many fronts, including that of HIV risk. As a result, HIV programs in Thailand are the key interventions undertaken in relation to young women sex workers' health. A small-scale study used semistructured interviews to explore the participation reports of five young women sex workers, as well as the related views of two community support workers, who lived and worked in Bangkok, Thailand. This study is considered in the light of current research on - as well as new opportunities and challenges offered for - participation by vulnerable groups in the context of digital society. Thematic analysis of the interview data identified barriers to participation, including the illegality of sex work, fear, and lack of trust of the authorities, as well as widespread social stigma. Such barriers resulted in young women seeking anonymity. Yet, promisingly, young women positioned themselves as experts; they are involved in peer education and are supportive of greater involvement in HIV programs, such as further educational initiatives and collective actions. There is a need for a more empowerment-oriented participation practice positioning young women sex workers as expert educators and codecision makers within a model of participation that is also accountable, such as including young women as members of program boards. Beyond current norms, there are new opportunities emerging because of the increasing availability of smartphone/Internet technology. These can support activist and codesign participation by young women sex workers in HIV programs. However, any developments in participation must maximize opportunities carefully, taking into consideration the difficult social environment faced by young women sex workers as well

Evaluation of the Wave Energy Conversion Efficiency in Various Coastal Environments

Directory of Open Access Journals (Sweden)

Eugen Rusu

2014-06-01

Full Text Available The main objective of the present work was to assess and compare the wave power resources in various offshore and nearshore areas. From this perspective, three different groups of coastal environments were considered: the western Iberian nearshore, islands and an enclosed environment with sea waves, respectively. Some of the most representative existent wave converters were evaluated in the analysis and a second objective was to compare their performances at the considered locations, and in this way to determine which is better suited for potential commercial exploitation. In order to estimate the electric power production expected in a certain location, the bivariate distributions of the occurrences corresponding to the sea states, defined by the significant wave height and the energy period, were constructed in each coastal area. The wave data were provided by hindcast studies performed with numerical wave models or based on measurements. The transformation efficiency of the wave energy into electricity is evaluated via the load factor and also through the capture width, defined as the ratio between the electric power estimated to be produced by each specific wave energy converters (WEC and the expected wave power corresponding to the location considered. Finally, by evaluating these two different indicators, comparisons of the performances of three WEC types (Aqua Buoy, Pelamis and Wave Dragon in the three different groups of coastal environments considered have been also carried out. The work provides valuable information related to the effectiveness of various technologies for the wave energy extraction that would operate in different coastal environments.

Sustainability of environment-assisted energy transfer in quantum photobiological complexes

Energy Technology Data Exchange (ETDEWEB)

Zloshchastiev, Konstantin G. [Institute of Systems Science, Durban University of Technology (South Africa)

2017-09-15

It is shown that quantum sustainability is a universal phenomenon which emerges during environment-assisted electronic excitation energy transfer (EET) in photobiological complexes (PBCs), such as photosynthetic reaction centers and centers of melanogenesis. We demonstrate that quantum photobiological systems must be sustainable for them to simultaneously endure continuous energy transfer and keep their internal structure from destruction or critical instability. These quantum effects occur due to the interaction of PBCs with their environment which can be described by means of the reduced density operator and effective non-Hermitian Hamiltonian (NH). Sustainable NH models of EET predict the coherence beats, followed by the decrease of coherence down to a small, yet non-zero value. This indicates that in sustainable PBCs, quantum effects survive on a much larger time scale than the energy relaxation of an exciton. We show that sustainable evolution significantly lowers the entropy of PBCs and improves the speed and capacity of EET. (copyright 2017 by WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

Economic development, accompanying with environmental damage and energy depletion, becomes essential nowadays. There is a complicated and comprehensive interaction between economics, environment and energy. Understanding the operating mechanism of Energy-Environment-Economy model (3E) and its key factors is the inherent part in dealing with the issue. In this paper, we combine System Dynamics model and Geographic Information System to analyze the energy-environment-economy (3E) system both temporally and spatially, which explicitly explore the interaction of economics, energy, and environment and effects of the key influencing factors. Beijing is selected as a case study to verify our SD-GIS model. Alternative scenarios, e.g., current, technology, energy and environment scenarios are explored and compared. Simulation results shows that, current scenario is not sustainable; technology scenario is applicable to economic growth; environment scenario maintains a balanced path of development for long term stability. Policy-making insights are given based on our results and analysis. Copyright © 2018 Elsevier Inc. All rights reserved.

Energy in the environment and the second law of thermodynamics

Science.gov (United States)

Mueller, R. F.

1972-01-01

The relationship between the consumption of energy by technological cultures and the second law of thermodynamics is discussed. The analysis is based on a description of the operation of a mechanical device which consumes energy. It is concluded that the flow of energy in manifold spontaneous conditions, which play a vital role in the operation of any technological process, remove most of the energy flow path from the control of the operator. It is stated that the increased efficiency of a process can benefit the environment only as much as this efficiency enables the total energy input to be reduced for a given level of production and increasing efficiency cannot meet the problems of an increased rate of energy utilization.

SP Swedish Testing and Research Institute's P-marking quality assurance scheme for buildings, products, services etc., now includes P-marking of indoor environment and energy use performance in buildings. The rules for the system, which cover new buildings, renovation and existing buildings, are set out in SP's certification rules no. SPCR 114E, specifying requirements in respect of both energy use and indoor environment management. Over the last ten years, SP has carried out considerable work in the field of the indoor environment, resulting in the development of a quality assurance system concentrating on achieving a high quality indoor environment. This quality assurance system has been successfully applied to schools, offices and dwellings. However, the performance of a building is determined not only by a good indoor environment, but also by low impact on the external environment as a result of energy use in the building. In some cases, concentrating on either good indoor environment or energy efficiency may result in an adverse effect on the other aspect, and so the quality assurance system for indoor environments been extended with a section dealing with energy use. This document is a handbook for inspection of documentation concerning quality assurance of energy use (primary energy analysis, determination of energy targets, energy management systems etc.). It can also be helpful when drawing up checklists for the organisation that is applying for P-marking. The book concentrates on requirements for approved certification of energy use in connection with P-marking of indoor environments and energy use in existing buildings: it does not cover requirements for certification of indoor environments. It starts by describing targeting, aims and requirements for P-marking of energy use, followed by presentation of some examples of inspections of collected documentation.

2018-03-01

Full Text Available While a mixture of residential and non-residential uses in urban development has advantages in reducing transportation energy consumption and improving efficiency of land utilization, the patterns of energy consumption in mixed-use buildings are largely unknown. To understand associations between the built environment and energy consumption and to find effective strategies for energy saving, this study aims to examine how the gas and electricity energy consumption of mixed-use properties is influenced by the characteristics of the immediate surroundings of the building as well as by the building’s attributes. The sample for this study is 22,109 mixed-use buildings in Seoul, Korea and the main source of outcome is electricity and gas energy consumption data retrieved from the open system of building data in 2015 and 2016. The regression results showed that a higher proportion of non-residential uses in mixed-use buildings was positively associated with higher electricity consumption overall but that it reduced gas energy use during the winter. In particular, increased restaurant and service use significantly influenced electricity consumption in the buildings. With regard to surrounding built environment, higher impervious surfaces and dense development near the buildings increased the electricity consumption of the buildings but it reduced gas energy consumption. Our results imply that, through the mediating effects of UHIs, the built environment characteristics of immediate surroundings may have indirect effects on energy consumption in mixed-use buildings.

High expectations for Norway's Centres for Environment-friendly Energy Research (FME).The FME centres address a broad range of areas, allcentral to developing the energy sector of the future. The activities of the eight centres established in 2009 focus on renewable energy, raising energy efficiency, energy planning, and carbon capture and storage (CCS). In 2011 three new FME centres were established which focus on social science-related energy research. The FME scheme is a direct follow-up of the broad-based political agreement on climate policy achieved in the Storting in January 2008, and of the national RandD Energi21 strategy submitted in February 2008 to the Ministry of Petroleum and Energy. In April 2008 the Research Council of Norway's Executive Board decided to launch a process to establish centres for environment-friendly energy research, and a funding announcement was issued that same year. In 2010 it was decided that additional FME centres would be established in the field of social science-related energy research. After a thorough assessment of each project (based on feasibility, scientific merit, potential to generate value creation and innovation, and composition of the consortium) eight applicants were selected to become FME centres in February 2009. A new call for proposals was issued in 2010, and three more centres were awarded FME status in February 2011. The objective of the FME scheme is to establish time-limited research centres which conduct concentrated, focused and long-term research of high international calibre in order to solve specific challenges in the energy sphere. The selected centres must exhibit higher goals, a longer-term perspective and a more concentrated focus than is required under other funding instruments for the same scientific area. The make-up of the centres is critical to achieving this objective. The centres bring together Norway's leading research institutions and key players in private enterprise, the

They will play essential role in Low Carbon Economy. The model of Low Carbon Economy-Energy-Electricity-Environment and an outlook of Chinese economic growth, energy-electricity demand, and renewable energy generation have been studied in this paper. It has been shown that China would save energy 4.38 billion toe and reduce CO2 emission 16.55 billion ton by EUM, and would save energy 1.5 billion toe and reduce CO2 emission 5.7 Btons by IRSP during 2010-2030.

Policy analysis for energy efficiency in the built environment in Spain

Energy efficiency is considered one of the most cost effective ways to enhance security of energy supply and reduce greenhouse gas emissions. According to Europe's Energy Efficiency Plan, the biggest energy savings potential in the EU lies in the built environment. However, the many barriers to energy efficiency have prevented the implementation of the existing potential so far. This paper evaluates the existing policy instruments aimed at energy efficiency in buildings in Spain as laid down in the 2nd National Energy Efficiency Action Plan (NEEAP). The results show that the current policy package is insufficient to yield the existing energy savings potential in this sector. As much of the savings potential can be found in existing buildings and realization of this potential very much relies on voluntary action, the renovation sector is in need of an appropriate financial framework that mobilizes sufficient public and private financial resources, and transparent and efficient mechanisms to ensure the return on investment and payments from those who benefit from the renovation. Such financial framework needs to be supported by a regulatory framework that is tuned to existing buildings and an organizational framework that effectively connects the different policy layers in Spain. - Highlights: • We evaluate Spain's policies for efficiency improvement in the built environment. • We show that the policy measures in the 2nd NEEAP are insufficient to realize the savings potential. • Especially, the policy package for existing buildings needs to be strengthened

Investigation of building energy autonomy in the sahelian environment

In this study, the energy generation of a set of photovoltaic panels is compared with the energy load of a building in order to analyse its autonomy in the sahelian environment when taking into account, the orientation, the insulation and the energy transfer optimisation of its windows. The Type 56 TRNSYS multizone building model is utilized for the energy load simulation and the Type 94 model of the same code enables the coupling of photovoltaic (PV) panels with the building. Without insulation, the PV energy generation represents 73.52 and 111.79% of the building electric energy load, respectively for poly-crystalline and mono-crystalline panels. For the same PV characteristics and when we insulate the roof and the floor, the energy generation increases to represent successively 121.09 and 184.13%. In the meantime, for building without insulation and with insulate the roof, the floor and 2 cm insulated walls, the energy consumption ratios decrease respectively from 201.13 to 105.20 kWh/m 2 /year. The investigations finally show that it is even possible to generate excess energy (positive energy building) and reduce the number and incident surface area of the PV panels if we conjugate the previous model with building passive architectural design mode (orientation, solar protection ...).

The specter of global climate change is arguably the most pressing scientific, social and ethical issue of our time. Although the relatively small field of astronomy represents only a fraction of the total human carbon emissions, astronomers have a great potential, and therefore perhaps a great responsibility, to educate themselves and the public on this issue. In addition, the average per capita carbon emissions of professional astronomers are not small, and our profession can do much to reduce its energy consumption and maximize the cost-benefit ratio of our work. At the January AAS meeting, we are organizing a half-day splinter meeting titled "Energy, the Environment and Astronomy: Education and Action". The focus will be on energy conservation and education as it relates to professional astronomy. Education focuses on informing ourselves, our students and the general public with which we interact, about the real issues, the necessary actions, and the likely consequences of various energy consumption and carbon emission scenarios. Action focuses on effective energy conservation and renewable energy initiatives within professional astronomy. Air travel, solar energy at ground-based observatories, and Gemini's "Green Initiative” are among the topics that will be discussed. The splinter meeting will be open to all and will include expert speakers from outside astronomy, contributed talks by astronomers, and a discussion session.

Energy technologies and the environment: Environmental information handbook

Energy Technology Data Exchange (ETDEWEB)

1988-10-01

This revision of Energy Technologies and the Environment reflects the changes in energy supply and demand, focus of environmental concern, and emphasis of energy research and development that have occurred since publication of the earlier edition in 1980. The increase in availability of oil and natural gas, at least for the near term, is responsible in part for a reduced emphasis on development of replacement fuels and technologies. Trends in energy development also have been influenced by an increased reliance on private industry initiatives, and a correspondingly reduced government involvement, in demonstrating more developed technologies. Environmental concerns related to acid rain and waste management continue to increase the demand for development of innovative energy systems. The basic criteria for including a technology in this report are that (1) the technology is a major current or potential future energy supply and (2) significant changes in employing or understanding the technology have occurred since publication of the 1980 edition. Coal is seen to be a continuing major source of energy supply, and thus chapters pertaining to the principal coal technologies have been revised from the 1980 edition (those on coal mining and preparation, conventional coal-fired power plants, fluidized-bed combustion, coal gasification, and coal liquefaction) or added as necessary to include emerging technologies (those on oil shale, combined-cycle power plants, coal-liquid mixtures, and fuel cells).

The purpose of this study was to identify and compare energy requirements specific to Special Operations Forces in field training, in both cool and hot environments. Three separate training sessions were evaluated, 2 in a hot environment (n = 21) and 1 in a cool environment (n = 8). Total energy expenditure was calculated using doubly labeled water. Dietary intake was assessed via self-report at the end of each training mission day, and macronutrient intakes were calculated. Across the 3 missions, mean energy expenditure (4618 ± 1350 kcal/day) exceeded mean energy intake (2429 ± 838 kcal/day) by an average of 2200 kcal/day. Macronutrient intakes (carbohydrates (g/(kg·day body weight (bw)) -1 ) = 3.2 ± 1.2; protein (g/(kg·day bw) -1 ) = 1.3 ± 0.7; fat (g/(kg·day bw) -1 ) = 1.2 ± 0.7) showed inadequate carbohydrate and possibly protein intake across the study period, compared with common recommendations. Total energy expenditures were found to be similar between hot (4664 ± 1399 kcal/day) and cool (4549 ± 1221 kcal/day) environments. However, energy intake was found to be higher in the cool (3001 ± 900 kcal/day) compared with hot (2200 ± 711 kcal/day) environments. Based on the identified energy deficit, high variation in energy expenditures, and poor macronutrient intake, a greater attention to feeding practices during similar training scenarios for Special Operations Forces is needed to help maintain performance and health. The differences in environmental heat stress between the 2 climates/environments had no observed effect on energy expenditures, but may have influenced intakes.

Pre-travel health assessments aim to promote risk reduction through preventive measures and safe behavior, including ensuring travelers are up-to-date with their immunizations. However, studies assessing pre-travel health-seeking practices from a variety of medical and non-medical sources and vaccine uptake prior to travel to both developing and developed countries within the Asia-Pacific region are scarce. Cross-sectional surveys were conducted between July and December 2007 to assess pre-travel health seeking practices, including advice from health professionals, health information from other sources and vaccine uptake, in a sample of travelers departing Sydney and Bangkok airports. A two-stage cluster sampling technique was used to ensure representativeness of travelers and travel destinations. Pre-travel health seeking practices were assessed using a self-administered questionnaire distributed at the check-in queues of departing flights. Logistic regression models were used to identify significant factors associated with seeking pre-travel health advice from a health professional, reported separately for Australian residents, residents of other Western countries and residents of countries in Asia. A total of 843 surveys were included in the final sample (Sydney 729, response rate 56%; Bangkok 114, response rate 60%). Overall, pre-travel health information from any source was sought by 415 (49%) respondents with 298 (35%) seeking pre-travel advice from a health professional, the majority through general practice. Receipt of a pre-travel vaccine was reported by 100 (12%) respondents. Significant factors associated with seeking pre-travel health advice from a health professional differed by region of residence. Asian travelers were less likely to report seeking pre-travel health advice and uptake of pre-travel vaccines than Australian or other Western travelers. Migrant Australians were less likely to report seeking pre-travel health advice than Australian

Full Text Available Most of the people have an idea of what renewable energy sources are and what they can offer us. The majority of people are also very aware of the impact that non-renewable energy is having on the environment. The adage reduce, reuse, recycle is commonly recited today by adults and children alike. We have started to see an increase in the reduction of waste and consumption of energy and the recycling and reuse of products we use. It is time to see an increase, however, in the use of renewable energy.

Understanding the physical dynamics and ecological interactions in tidal stream energy environments

Science.gov (United States)

Fraser, Shaun; Williamson, Benjamin J.; Nikora, Vladimir; Scott, Beth E.

2017-04-01

Tidal stream energy devices are intended to operate in energetic physical environments characterised by high flows and extreme turbulence. These environments are often of ecological importance to a range of marine species. Understanding the physical dynamics and ecological interactions at fine scales in such sites is essential for device/array design and to understand environmental impacts. However, investigating fine scale characteristics requires high resolution field measurements which are difficult to attain and interpret, with data often confounded by interference related to turbulence. Consequently, field observations in tidal stream energy environments are limited and require the development of specialised analysis methods and so significant knowledge gaps are still present. The seabed mounted FLOWBEC platform is addressing these knowledge gaps using upward facing instruments to collect information from around marine energy infrastructure. Multifrequency and multibeam echosounder data provide detailed information on the distribution and interactions of biological targets, such as fish and diving seabirds, while simultaneously recording the scales and intensity of turbulence. Novel processing methodologies and instrument integration techniques have been developed which combine different data types and successfully separates signal from noise to reveal new evidence about the behaviour of mobile species and the structure of turbulence at all speeds of the tide and throughout the water column. Multiple platform deployments in the presence and absence of marine energy infrastructure reveal the natural characteristics of high energy sites, and enable the interpretation of the physical and biological impacts of tidal stream devices. These methods and results are relevant to the design and consenting of marine renewable energy technologies, and provide novel information on the use of turbulence for foraging opportunities in high energy sites by mobile species.

The above-named seminar was held in Bangkok, Thailand, on January 30, 2001, and covered three kinds of industries of ceramics, glass, and aluminum. Approximately 200 people attended the meeting, consisting of NEDO (New Energy and Industrial Technology Development Organization)-affiliated people and 16 lecturers from Japan, and Thai participants. The seminar comprised a 'keynote address' and 'lectures on engineering' that aimed at the three industries as a whole, and 'lectures on engineering' and 'cases and activities for energy conservation' that aimed, respectively, at the three industries. Lectures were delivered on operating technologies which were already in practical use and on state-of-the-art technologies. The keynote address, entitled 'Global warming prevention and industrial furnaces,' covered the results of the 'High-performance industrial furnace field test project.' The lectures on engineering dealt with the 'instrumentation control system' and 'heat insulation technology' which were basic technologies for energy conservation and 'diagnosis technology and practice' which aimed at the enhancement of energy conservation after the start of operation. Questions and answers were earnestly exchanged. (NEDO)

Negotiating energy dynamics through embodied action in a materially structured environment

Directory of Open Access Journals (Sweden)

Rachel E. Scherr

2013-07-01

Full Text Available We provide evidence that a learning activity called Energy Theater engages learners with key conceptual issues in the learning of energy, including disambiguating matter flow and energy flow and theorizing mechanisms for energy transformation. A participationist theory of learning, in which learning is indicated by changes in speech and behavior, supports ethnographic analysis of learners’ embodied interactions with each other and the material setting. We conduct detailed analysis to build plausible causal links between specific features of Energy Theater and the conceptual engagement that we observe. Disambiguation of matter and energy appears to be promoted especially by the material structure of the Energy Theater environment, in which energy is represented by participants, while objects are represented by areas demarcated by loops of rope. Theorizing mechanisms of energy transformation is promoted especially by Energy Theater’s embodied action, which necessitates modeling the time ordering of energy transformations.

Energy and Environment Directorate Status Report March 2006

Long, J S

2006-01-01

The Energy and Environment Directorate (E and ED) is one of 13 directorates at Lawrence Livermore National Laboratory (LLNL), which is operated by the University of California (UC) for the U.S. Department of Energy's National Nuclear Security Administration (NNSA). We operate in the context of a national security laboratory and focus on meeting major national needs, especially from a long-term perspective. In the LLNL context, E and ED is a hybrid ''program'' and ''discipline'' directorate, combining the program development responsibilities in the national energy and environment arenas to the benefit of the entire Laboratory and also serving as the Laboratory's science base of atmospheric, earth, environmental, and energy science. This Status Report is part of the annual evaluation process required by the Department of Energy (DOE) as part of its contract with UC. The annual review typically will focus on about one third of the activities and programs of a directorate, so that the entire organization is evaluated over a three-year window. This year's review is focused on the basic science foundations for the directorate and two major program areas in the directorate, with an update from a third program. The programs for review are: (1) Earth System Science and Engineering; (2) Nuclear Systems Science and Engineering; and (3) NARAC/IMAAC update. Major questions to be addressed during this review include: (1) Are the programmatic directions appropriate? How can they be improved? (2) What actions can E and ED take to ensure success? How well poised for success are the current staff and facilities? What additions are needed? (3) What recommendations can be made to the Director and the University? This Status Report provides background information on the entire directorate including the parts of the directorate that are the focus of this year's review by the Energy and Environment Directorate Review Committee, to be held March 6-9, 2006.

The Investment Environment for Renewable Energy Development in Lithuania: The Electricity Sector

Directory of Open Access Journals (Sweden)

Milčiuvienė Saulė

2014-06-01

Full Text Available The article analyzes the investment environment in renewable electricity generation capacities, evaluating the credibility of long term renewable energy targets, the stability of promotion schemes and the impartiality of national administrative procedure. The article explores two main questions: (i are the EU and Lithuanian energy policy targets and promotion schemes credible enough to convince private investors to put their money in renewable energy development; (ii does national administrative procedure put a disproportional burden on renewable energy investors or on certain group of investors? The assessment of the investment environment includes a large number of criteria, but we analyze three of them: the stability of long term strategy; the attractiveness of promotionmeasures; and the simplicity and transparency of administrative procedure. Two further criteria are investigated: the stability of targets in renewable energy and the stability of promotional measures. The greatest uncertainty for investors occurs because of constantly changing support schemes of renewable energy sources-schemes that are not harmonized among the member States. At the national level the main driver in the development of small generators is the feed-in tariff. However, the high feed-in tariff does not always guarantee the smooth development of small scale generators of renewable energy.

Assessing the co-benefits of greenhouse gas reduction: health benefits of particulate matter related inspection and maintenance programs in Bangkok, Thailand.

Science.gov (United States)

Li, Ying; Crawford-Brown, Douglas J

2011-04-15

Since the 1990s, the capital city of Thailand, Bangkok has been suffering from severe ambient particulate matter (PM) pollution mainly attributable to its wide use of diesel-fueled vehicles and motorcycles with poor emission performance. While the Thai government strives to reduce emissions from transportation through enforcing policy measures, the link between specific control policies and associated health impacts is inadequately studied. This link is especially important in exploring the co-benefits of greenhouse gas emissions reductions, which often brings reduction in other pollutants such as PM. This paper quantifies the health benefits potentially achieved by the new PM-related I/M programs targeting all diesel vehicles and motorcycles in the Bangkok Metropolitan Area (BMA). The benefits are estimated by using a framework that integrates policy scenario development, exposure assessment, exposure-response assessment and economic valuation. The results indicate that the total health damage due to the year 2000 PM emissions from vehicles in the BMA was equivalent to 2.4% of Thailand's GDP. Under the business-as-usual (BAU) scenario, total vehicular PM emissions in the BMA will increase considerably over time due to the rapid growth in vehicle population, even if the fleet average emission rates are projected to decrease over time as the result of participation of Thailand in post-Copenhagen climate change strategies. By 2015, the total health damage is estimated to increase by 2.5 times relative to the year 2000. However, control policies targeting PM emissions from automobiles, such as the PM-oriented I/M programs, could yield substantial health benefits relative to the BAU scenario, and serve as co-benefits of greenhouse gas control strategies. Despite uncertainty associated with the key assumptions used to estimate benefits, we find that with a high level confidence, the I/M programs will produce health benefits whose economic impacts considerably outweigh

We explore excitonic energy transfer dynamics in a molecular dimer system coupled to both structured and unstructured oscillator environments. By extending the reaction coordinate master equation technique developed by Iles-Smith et al. [Phys. Rev. A 90, 032114 (2014)], we go beyond the commonly used Born-Markov approximations to incorporate system-environment correlations and the resultant non-Markovian dynamical effects. We obtain energy transfer dynamics for both underdamped and overdamped oscillator environments that are in perfect agreement with the numerical hierarchical equations of motion over a wide range of parameters. Furthermore, we show that the Zusman equations, which may be obtained in a semiclassical limit of the reaction coordinate model, are often incapable of describing the correct dynamical behaviour. This demonstrates the necessity of properly accounting for quantum correlations generated between the system and its environment when the Born-Markov approximations no longer hold. Finally, we apply the reaction coordinate formalism to the case of a structured environment comprising of both underdamped (i.e., sharply peaked) and overdamped (broad) components simultaneously. We find that though an enhancement of the dimer energy transfer rate can be obtained when compared to an unstructured environment, its magnitude is rather sensitive to both the dimer-peak resonance conditions and the relative strengths of the underdamped and overdamped contributions.

Competitive energy markets. The effective route to improving the environment

International Nuclear Information System (INIS)

Swinden, D.J.

1996-01-01

Market forces, operating in an increasingly competitive energy market, are a preferred route to achieving environmental and energy efficiency benefits, than those which can be achieved through a managed approach adopted by many governments. It is shown, through examples, how electricity is a catalyst for change at several levels in business, the community and the general economy. Experience in the United Kingdom indicates that free market forces and inter-energy competition not only help improve the regional and therefore national economy, but they offer a very effective way of introducing improvements in energy efficiency and the environment. Governments should establish the framework for competition and regulation but not attempt to manage an industry, which is invariably done more effectively by those who run them. (author)

Purpose of the National Conference on Energy and Environment is to examine the energy cycle from the environmental, economic and employment standpoints to provide with a new frame of reference all actors concerned. The choice of the Mediterranean Sea as a subject in one of the themes under discussion, apart from being obviously grounded on Italy's central location in it, is explained by the number of critical factors showing in the area; among which energy aspects (as regards energy production, transportation and use), the high level of urbanization of its coasts, impact and conflicts for resource utilisation generated by and between economic activities - agriculture, industry, fisheries, tourism, sea freighting, and so on - and the uniqueness and variety of Mediterranean ecosystems

Enhancing energy security in Malayia: the challenges towards sustainable environment

Sahid, E J M; Peng, L Y; Siang, C Ch

2013-01-01

Energy is known as one of the essential ingredients for economic development and security of energy supply is crucial in ensuring continuous economic development of a country. Malaysia's proven domestic oil reserves are estimated to last for another 25 years, while that of gas for another 39 years as of 2011. Despite the depleting indigenous energy resources, the primary energy demand has continued to grow robustly, at an annual rate of 6.3 percent per year from 1990 to 2010, while the primary energy import has grown 7.2% per year and the primary energy export has grown at a slower rate of 1.9% per year. This worrying trend is further compounded by the faster rate of primary oil import averaging 10.5% per year while the primary energy export has shrink at a rate of 1.4% per year. This paper has identified two main concerns namely overdependence on fossil fuel and increasing energy import dependency in creating a precarious position towards energy self-sufficiency. The study will analyse the energy security of the country and explore possible options and challenges in enhancing the energy supply security toward sustainable environment.

Men have developed technologies, sometimes surprising, allowing to capture a small part of the kinetic energy carried by rivers, streams or waves. Classical hydropower plants, from big dams to micro-hydroelectric plants, are well-known technologies, but beside these, the most ingenious systems can be found on the marine side: submarine turbines, 'sea snake' wave energy converters, offshore wind turbines or production of biomass fuels from algae cultivation. These new energy sources are going to occupy an increasing place in tomorrow's energy landscape but, like for any human intervention in the natural ecosystems, care must be taken to exploit the energy of the precious water resource in the respect of the environment.

Genomes of fungi relevant to energy and environment are in focus of the Fungal Genomic Program at the US Department of Energy Joint Genome Institute (JGI). One of its projects, the Genomics Encyclopedia of Fungi, targets fungi related to plant health (symbionts, pathogens, and biocontrol agents) and biorefinery processes (cellulose degradation, sugar fermentation, industrial hosts) by means of genome sequencing and analysis. New chapters of the Encyclopedia can be opened with user proposals to the JGI Community Sequencing Program (CSP). Another JGI project, the 1000 fungal genomes, explores fungal diversity on genome level at scale and is open for users to nominate new species for sequencing. Over 200 fungal genomes have been sequenced by JGI to date and released through MycoCosm (www.jgi.doe.gov/fungi), a fungal web-portal, which integrates sequence and functional data with genome analysis tools for user community. Sequence analysis supported by functional genomics leads to developing parts list for complex systems ranging from ecosystems of biofuel crops to biorefineries. Recent examples of such parts suggested by comparative genomics and functional analysis in these areas are presented here.

Nuclear energy has a strategic place within the structure of the country’s energy system. The energy transformation technology as well as the extremely high requirements regarding nuclear safety call for the availability of scientific, applied, and operational potential, and for an adequate culture of safe use of nuclear energy. In that aspect, the research reactor as a material base, and its scientific and technical personnel, represent a solid basis for the development of nuclear energy in our country. The acquired scientific experience and qualification in reactor operation are a precondition for the equal in rights participation of the country in the international cooperation and the approaching to the European structures, and assurance of the national interests

Planning initiatives in many regions and communities aim to reduce transportation energy use, decrease emissions, and achieve related environmental benefits by changing land use. This report reviews and summarizes findings from existing literature on the relationship between the built environment and transportation energy use and greenhouse gas emissions, identifying results trends as well as potential future actions. The indirect influence of federal transportation and housing policies, as well as the direct impact of municipal regulation on land use are examined for their effect on transportation patterns and energy use. Special attention is given to the 'four D' factors of density, diversity, design and accessibility. The report concludes that policy-driven changes to the built environment could reduce transportation energy and GHG emissions from less than 1% to as much as 10% by 2050, the equivalent of 16%-18% of present-day urban light-duty-vehicle travel. This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a Department of Energy-sponsored multi-agency project initiated to pinpoint underexplored strategies for abating GHGs and reducing petroleum dependence related to transportation.

Graphical abstract: Mechanisms of IVR in multi-tiers of intramolecular energy levels in different molecular environments are investigated. - Abstract: Transient femtosecond-IR-pump-UV-absorption probe-spectroscopy has been employed to shed light on the nature of intramolecular vibrational energy transfer (IVR) in dense molecular environments ranging from the diluted gas phase to the liquid. A general feature in our experiments and those of others is that IVR proceeds via multiple timescales if overtones or combination vibrations of high frequency modes are excited. It has been found that collisions enhance IVR if its (slower) timescales can compete with collisions. This enhancement is, however, much more weaker and rather inefficient as opposed to the effect of collisions on intermolecular energy transfer which is well known. In a series of experiments we found that IVR depends not significantly on the average energy transferred in a collision but rather on the number of collisions. The collisions are much less efficient in affecting IVR than VET. We conclude that collision induced broadening of vibrational energy levels reduces the energy gaps and enhances existing couplings between tiers. The present results are an important step forward to rationalize and understand apparently different and not consistent results from different groups on different molecular systems between gas and liquid phases.

Increased energy security and reduced carbon emissions pose significant challenges for science and technology. However, they also create substantial opportunities for innovative research and development. In this review paper, we highlight some of the key opportunities and mention public policies that are needed to enable the efforts and to maximize the probability of their success. Climate is among the uttermost nonlinear behaviors found around us. As recent studies showed the possible effect of cosmic rays on the Earth's climate, we investigate how complex interactions between the planet and its environment can be responsible for climate anomalies.

Thousands of aerospace innovations have found their way into everyday use, and future National Aeronautics and Space Administration (NASA) missions promise to provide many more spinoff opportunities. Each spinoff has contributed some measure of benefit to the national economy, productivity, or lifestyle. In total, these spinoffs represent a substantial dividend on the national investment in aerospace research. Along with examples of the many terrestrial applications of NASA technology to energy and the environment, this paper presents the mechanisms by which NASA promotes technology transfer. Also discussed are new NASA initiatives in superconductivity research, global warming, and aeropropulsion.

Referring to the concept of sustainable development, the environment is said to be sustainable if the fulfillment of three pillars of development that is economic, social and ecological or the environment itself. The environment can sustained in the principle of ecology or basic principles of environmental science, when the three environmental components, namely the natural environment, the artificial environment (the built environment) and the social environment can be aligned for sustainability. The natural environment in this study is the water resources, the artificial environment is micro hydroelectric power generation (MHPG), and the social environment is the community living around the MHPG. The existence of MHPG is intended for the sustainability of special electrical energy for areas not yet reached by electricity derived from the state electricity company (SEC). The utilization of MHPG Singalaga in South Ogan Komering Ulu (OKUS) district is not only intended for economic, ecological, and social sustainability in Southern OKU district especially those who live in Singalaga Village, Kisam Tinggi District. This paper discusses the economic, ecological and social benefits of water resources utilization in Southern OKU District for MHPG Singalaga. The direct economic benefits that arise for people living around MHPG Singalaga is the cost incurred by the community for the use of electricity is less than if the community uses electricity coming from outside the MHPG. The cost to society in the form of dues amounting to IDR 15,000 a month / household.

Full Text Available Objective: The main goal of the article is to propose a new framework exhibiting relationship between tangible dimension and all other intangible dimensions of SERVQUAL used to analyse the relation to re-patronage intention. Research Design & Methods: Hypothesised relationships were tested on data which was collected in Bangkok area using a survey questionnaire. Final sample consisted of 225 respondents, frequent visitors of community malls. The data was analysed using exploratory factor analysis as well as simple and multiple regression analysis. The six constructs, studied in this paper, were examined for differences in means across all demographic variables by employing analysis of variance or ANOVA. Findings: The results exposed that tangible dimension had significant correlation to reliability, empathy, responsiveness and assurance dimensions consecutively. Multiple regression analysis demonstrated that re-patronage intention was explained by empathy, responsiveness and assurance dimensions, not reliability dimension. The ANOVA tests showed no significant differences in means of general data and all other constructs. Implications & Recommendations: To make shoppers to come back to the malls, managers should recognize the important role of tangible items as an antecedent to intangible items. Retail developers could devote more efforts to maximize the attractiveness of tangible elements and identify the weak areas of service quality by examining the multi-item constructs used to measure service quality. Contribution & Value Added: This study proposed and tested a modified conceptual model adapted from that proposed by Reimer and Kuehn (2005.

Full Text Available Impacts from floods in urban areas can be diverse and wide ranging. These can include the loss of human life, infrastructure and property damages, as well as other kinds of nuisance and inconvenience to urban life. Hence, the ability to identify and quantify wider ranging effects from floods is of the utmost importance to urban flood managers and infrastructure operators. The present work provides a contribution in this direction and describes a methodological framework for analysing cascading effects from floods that has been applied for the Sukhumvit area in Bangkok (Thailand. It demonstrates that the effects from floods can be much broader in their reach and magnitude than the sole impacts incurred from direct and immediate losses. In Sukhumvit, these include loss of critical services, assets and goods, traffic congestion and delays in transportation, loss of business and income, disturbances and discomfort to the residents, and all these can be traced with the careful analysis of cascading effects. The present work explored the use of different visualization options to present the findings. These include a casual loop diagram, a HAZUR resilience map, a tree diagram and GIS maps.

Ethnic and racial differences in infant skin have not been well characterized. The purpose of this study was to establish whether there are ethnic differences and similarities in the stratum corneum (SC) functions of Thai and Chinese infants. Healthy infants 6 to 24 months of age (N = 60; 30 Thai, 30 Chinese) who resided in Bangkok, Thailand, were enrolled. Transepidermal water loss (TEWL) and SC hydration (capacitance) on the thigh, buttock, and upper arm were measured. Ceramide content was determined in the SC on the upper arm. SC hydration was not remarkably different between the two ethnicities at any site measured, but TEWL was significantly higher in Chinese infants than in Thai infants at all sites. Hydration of the SC was not significantly correlated with age in either ethnicity. TEWL had significant but weak correlations with age on the thigh and upper arm in Thai infants. Ceramide content was significantly higher in Chinese SC than in Thai SC. No relationship between ceramide content and TEWL or hydration was observed in either ethnicity. The significant differences in TEWL and ceramide contents between Chinese and Thai infant skin could prove useful in designing skin care and diapering products that are best suited for each ethnicity. © 2017 Wiley Periodicals, Inc.

Developing Intensity–Duration–Frequency (IDF Curves under Climate Change Uncertainty: The Case of Bangkok, Thailand

2017-02-01

Full Text Available The magnitude and frequency of hydrological events are expected to increase in coming years due to climate change in megacities of Asia. Intensity–Duration–Frequency (IDF curves represent essential means to study effects on the performance of drainage systems. Therefore, the need for updating IDF curves comes from the necessity to gain better understanding of climate change effects. The present paper explores an approach based on spatial downscaling-temporal disaggregation method (DDM to develop future IDFs using stochastic weather generator, Long Ashton Research Station Weather Generator (LARS-WG and the rainfall disaggregation tool, Hyetos. The work was carried out for the case of Bangkok, Thailand. The application of LARS-WG to project extreme rainfalls showed promising results and nine global climate models (GCMs were used to estimate changes in IDF characteristics for future time periods of 2011–2030 and 2046–2065 under climate change scenarios. The IDFs derived from this approach were corrected using higher order equation to mitigate biases. IDFs from all GCMs showed increasing intensities in the future for all return periods. The work presented demonstrates the potential of this approach in projecting future climate scenarios for urban catchment where long term hourly rainfall data are not readily available.

Tokimatsu, Koji; Fujino, Jun'ichi; Konishi, Satoshi; Ogawa, Yuichi; Yamaji, Kenji

2003-01-01

Debates about whether or not to invest heavily in nuclear fusion as a future innovative energy option have been made within the context of energy technology development strategies. This is because the prospects for nuclear fusion are quite uncertain and the investments therefore carry the risk of quite large regrets, even though investment is needed in order to develop the technology. The timeframe by which nuclear fusion could become competitive in the energy market has not been adequately studied, nor has roles of the nuclear fusion in energy systems and the environment. The present study has two objectives. One is to reveal the conditions under which nuclear fusion could be introduced economically (hereafter, we refer to such introductory conditions as breakeven prices) in future energy systems. The other objective is to evaluate the future roles of nuclear fusion in energy systems and in the environment. Here we identify three roles that nuclear fusion will take on when breakeven prices are achieved: (i) a portion of the electricity market in 2100, (ii) reduction of annual global total energy systems cost, and (iii) mitigation of carbon tax (shadow price of carbon) under CO 2 constraints. Future uncertainties are key issues in evaluating nuclear fusion. Here we treated the following uncertainties: energy demand scenarios, introduction timeframe for nuclear fusion, capacity projections of nuclear fusion, CO 2 target in 2100, capacity utilization ratio of options in energy/environment technologies, and utility discount rates. From our investigations, we conclude that the presently designed nuclear fusion reactors may be ready for economical introduction into energy systems beginning around 2050-2060, and we can confirm that the favorable introduction of the reactors would reduce both the annual energy systems cost and the carbon tax (the shadow price of carbon) under a CO 2 concentration constraint

Resonance interaction energy between two entangled atoms in a photonic bandgap environment.

Science.gov (United States)

Notararigo, Valentina; Passante, Roberto; Rizzuto, Lucia

2018-03-26

We consider the resonance interaction energy between two identical entangled atoms, where one is in the excited state and the other in the ground state. They interact with the quantum electromagnetic field in the vacuum state and are placed in a photonic-bandgap environment with a dispersion relation quadratic near the gap edge and linear for low frequencies, while the atomic transition frequency is assumed to be inside the photonic gap and near its lower edge. This problem is strictly related to the coherent resonant energy transfer between atoms in external environments. The analysis involves both an isotropic three-dimensional model and the one-dimensional case. The resonance interaction asymptotically decays faster with distance compared to the free-space case, specifically as 1/r 2 compared to the 1/r free-space dependence in the three-dimensional case, and as 1/r compared to the oscillatory dependence in free space for the one-dimensional case. Nonetheless, the interaction energy remains significant and much stronger than dispersion interactions between atoms. On the other hand, spontaneous emission is strongly suppressed by the environment and the correlated state is thus preserved by the spontaneous-decay decoherence effects. We conclude that our configuration is suitable for observing the elusive quantum resonance interaction between entangled atoms.

Environment, energy, and economic performance

Energy Technology Data Exchange (ETDEWEB)

Oberndorfer, Ulrich

2009-09-25

This thesis analyzes the relationship between environmental regulation as well as energy market developments on the one hand, and economic performance on the other. Due to its economic effects environmental regulation is controversially disputed. The thesis shows, however, that the economic impacts of the recently adopted climate policy in Europe, namely of the implementation of the European Union Emission Trading Scheme, have been modest at most. Consistent with economic theory, the low stringency of this regulatory measure that is aimed at combating man-made climate change is identified as one important driver of this result. Moreover, results presented in this thesis also indicate the important role which the political economy plays for the design of environmental regulation in general. These mechanisms are shown to be a driver of the low stringency and, consequently, of the small economic effects during the first phase of the European Union Emission Trading Scheme. The thesis highlights the role of investment stimulation if the goal of environmental regulation is not only the protection of the environment, but also the compatibility with economic goals. This thesis also provides new insights into the role of energy market developments for the economy. In this respect, the relevance of the EU carbon market for the financial market performance of European electricity generators is shown. Besides, this thesis particularly demonstrates the paramount importance of oil market developments for the economy as a whole. It suggests that amongst all natural resources, oil is the most relevant one to the pricing of Eurozone energy stocks. It is also shown that besides oil prices, oil volatility plays an important role for stock market development. Finally, the thesis highlights the relevance of oil market developments to the overall economy, in showing that unemployment in Germany is strongly affected by oil price shocks. In this respect, it also opposes claims that the

Research on smart environments saturated with ubiquitous computing devices is rapidly advancing while raising serious privacy issues. According to recent studies, privacy concerns significantly hinder widespread adoption of smart home technologies. Previous work has shown that it is possible to infer the activities of daily living within environments equipped with wireless sensors by monitoring radio fingerprints and traffic patterns. Since data encryption cannot prevent privacy invasions exploiting transmission pattern analysis and statistical inference, various methods based on fake data generation for concealing traffic patterns have been studied. In this paper, we describe an energy-efficient, light-weight, low-latency algorithm for creating dummy activities that are semantically similar to the observed phenomena. By using these cloaking activities, the amount of  fake data transmissions can be flexibly controlled to support a trade-off between energy efficiency and privacy protection. According to the experiments using real data collected from a smart home environment, our proposed method can extend the lifetime of the network by more than 2× compared to the previous methods in the literature. Furthermore, the activity cloaking method supports low latency transmission of real data while also significantly reducing the accuracy of the wireless snooping attacks.

The project for energy saving dissemination activities and technological assistance for Thailand is carried out, and the FY 2000 results are reported. For Siam Iron and Steel (SISCO), the experts are dispatched for reviewing the operating conditions of the facilities constructed by the model project, their maintenance and examination, time series diagnosis of the recuperator performance, and providing technical assistance for fuel consumption and high-load combustion of the downstream unit. Furthermore, the site survey and technical assistance are provided for two newly selected Thai steel enterprises, Sahaviriya Steel Industries Public Co. (SSI) and the Bangkok Iron and Steel Works Co. (BISW). For SSI, it is predicted that energy of approximately 50Mcal/ton can be saved by, e.g., enhancement of waste heat recovery, enhancement of heat insulation of skid pipes, introduction of steel discharging temperature prediction system, and combustion control. For BISW, it is predicted that energy of approximately 25Mcal/ton can be saved by, e.g., enhancement of waste heat recovery and reduction of heat loss in the waste gas. (NEDO)

The development of energy and its influences on the environment

Energy consumption is increasing substantially as the world economy rapidly develops. The influences of energy development on the environment will become more conspicuous. Among them, pollution caused by burning fossil fuels draws the greatest attention from all nations. Some experts hold that, since the early eighties, a second upsurge of environmental concern has occurred because of the increasing environmental pollution and damage to the ecological balance on a large scale. The first environmental movement occurred between the fifties and the sixties. At that time, environmental pollution in industrialized countries was so serious that it threatened directly the life and security of people, exerted a tremendous influence on economic development, and caused serious social disturbances. Despite all these disadvantages, however, it appeared only in some factories and districts in those countries. Comparatively, both the pollution sources and their range were more limited. The United Nations held the Conference of Human Environment at Stockholm in Sweden at this time. It was a milestone for mankind to recognize the importance of and make efforts for environmental improvement. In the recent environmental movement, people are more concerned about problems that have an extremely harmful impact on large areas, including the problems of acid rain, ozonosphere destruction, greenhouse effects, etc. These problems attract a great deal of attention in countries all over the world. Concerned authorities in China have also begun to attach importance to these problems. This is especially true of energy consumption in China, as the main fuels in cities and large industrial bases coal and other fossil fuels, whereas 75 percent of the energy in the countryside is dependent on biomass energy. Such a pattern undoubtedly exerts a big influence on environmental pollution and undermines the ecological balance

Landing Marine-derived Renewable Energy: Optimising Power Cable Routing in the Nearshore Environment

Turner, Rosalind, ,, Dr.; Keane, Tom; Mullins, Brian; Phipps, Peter

2010-05-01

Numerous studies have demonstrated that a vast unexploited source of energy can be derived from the marine environment. Recent evolution of the energy market and looming EU renewable energy uptake targets for 2020 have driven a huge explosion of interest in exploiting this resource, triggering both governments and industry to move forward in undertaking feasibility assessments and demonstration projects for wave, tidal and offshore wind farms across coastlines. The locations which naturally lend themselves to high yield energy capture, are by definition, exposed and may be remote, located far from the end user of the electricity generated. A fundamental constraint to successfully exploiting these resources will be whether electricity generated in high energy, variable and constantly evolving environments can be brought safely and reliably to shore without the need for constant monitoring and maintenance of the subsea cables and landfall sites. In the case of riverine cable crossings superficial sediments would typically be used to trench and bury the cable. High energy coastal environments may be stripped of soft sediments. Any superficial sediments present at the site may be highly mobile and subject to re-suspension throughout the tidal cycle or under stormy conditions. EirGrid Plc. and Mott MacDonald Ireland Ltd. have been investigating the potential for routing a cable across the exposed Shannon estuary in Ireland. Information regarding the geological ground model, meteo-oceanographic and archaeological conditions of the proposed site was limited, necessitating a clear investigation strategy. The investigation included gathering site information on currents, bathymetry and geology through desk studies, hydrographic and geophysical surveys, an intrusive ground investigation and coastal erosion assessments at the landfall sites. The study identified a number of difficulties for trenching and protecting a cable through an exposed environment such as the Shannon

Heuristic Scheduling in Grid Environments: Reducing the Operational Energy Demand

Science.gov (United States)

Bodenstein, Christian

In a world where more and more businesses seem to trade in an online market, the supply of online services to the ever-growing demand could quickly reach its capacity limits. Online service providers may find themselves maxed out at peak operation levels during high-traffic timeslots but too little demand during low-traffic timeslots, although the latter is becoming less frequent. At this point deciding which user is allocated what level of service becomes essential. The concept of Grid computing could offer a meaningful alternative to conventional super-computing centres. Not only can Grids reach the same computing speeds as some of the fastest supercomputers, but distributed computing harbors a great energy-saving potential. When scheduling projects in such a Grid environment however, simply assigning one process to a system becomes so complex in calculation that schedules are often too late to execute, rendering their optimizations useless. Current schedulers attempt to maximize the utility, given some sort of constraint, often reverting to heuristics. This optimization often comes at the cost of environmental impact, in this case CO 2 emissions. This work proposes an alternate model of energy efficient scheduling while keeping a respectable amount of economic incentives untouched. Using this model, it is possible to reduce the total energy consumed by a Grid environment using 'just-in-time' flowtime management, paired with ranking nodes by efficiency.

Thesis. Energy is generally considered as the main access to the modern industrial society. The availability of sufficient amounts of energy as due to fundamental importance for the development of society. Besides the demand on economical energy maintenance, there are intensively occurring ecological and supply-technical aspects. whose importance advances permanently with the exponential increase of the energy consumption. A holistic analysis for the system man--enengy -environment regarding economical, ecological, and technical aspects is presented. The aim is to comprehend all significant influence factors and interactions as well as to compare and to evaluate the positive and negative effects of an increasing enengy consumption and its protection by alternative energy supply systems. For such complex systems new methods developed in the field of system engineering, especially cybernetic simulation, have to be used for the derivation of adequate aid for decision. (auth)

The inefficient use of energy by the different types of consumers of the Metropolitan area of Mexico City (ZMCM, this means, Mexico city and the municipalities of the Estado de Mexico, which constitute a single economic population unit), is one of the main causes for the production of polluting emissions into the atmosphere, specially of nitrogen oxide, sulfur dioxide and carbon monoxide. This originates a deterioration of the environment, which injures the health of the population. As a consequence, the private and public sectors have been forced to establish programs in order to improve the use of energy, as well as to preserve the environment. (Author)

Energy has been the fundamental tool in the development of the humanity for the production of estates and essential services in its nourishment and general welfare. In the measure that that has increased the population, it has been generated greater demand of energy to produce the necessary estates for the survival mainly in the urban centers or of consumption. This situation has generated the accelerated intervention of the energetic resources not renewable, originating imbalances in the natural ecosystems, during the exploration stages, development of large projects or in the direct consumption (when is tried of a primary consumption of energy as the firewood). Of other side, catastrophic environmental effects in the urban or industrial concentrations have been generated, caused by the combustion or burnt in a way primary or secondary of energy as the hot gases emission and radiations in concentrations that the troposphere can not dilute or deaden

From the beginning of mankind, the obtaining and use of energy was always made against the natural environment. But only after the Industrial Revolution the human civilization has endangered some ecosystems because an immeasurable, but also harmful in regard to natural resources, economic, sanitary and cultural development. The solutions pass through preserving what we have yet obtained, including its generalisation to the poor people of the world, but above all it needs the harmonization between this kind of development and the conservation of natural resources if we want a sustainable situation. In this way, the environmental management of the economic resources must replace gradually the mere economist management that we are using until all over the world. (Author)

Obesity and the built environment: changes in environmental cues cause energy imbalances.

Science.gov (United States)

Cohen, D A

2008-12-01

The past 30 years have seen dramatic changes in the food and physical activity environments, both of which contribute to the changes in human behavior that could explain obesity. This paper reviews documented changes in the food environment, changes in the physical activity environment and the mechanisms through which people respond to these environments, often without conscious awareness or control. The most important environmental changes have been increases in food accessibility, food salience and decreases in the cost of food. The increases in food marketing and advertising create food cues that artificially stimulate people to feel hungry. The existence of a metabolic pathway that allows excess energy to be stored as fat suggests that people were designed to overeat. Many internal mechanisms favor neurophysiologic responses to food cues that result in overconsumption. External cues, such as food abundance, food variety and food novelty, cause people to override internal signals of satiety. Other factors, such as conditioning and priming, tie food to other desirable outcomes, and thus increase the frequency that hunger is stimulated by environmental cues. People's natural response to the environmental cues are colored by framing, and judgments are flawed and biased depending on how information is presented. People lack insight into how the food environment affects them, and subsequently are unable to change the factors that are responsible for excessive energy consumption. Understanding the causal pathway for overconsumption will be necessary to interrupt the mechanisms that lead to obesity.

Analysis on Energy Consumption and Indoor Environment in Kunming, China

2012-10-01

Full Text Available The purposes of this study are to investigate and analyze the actual conditions of the urban residential energy consumption, and hence to ascertain what will be the important factors that influence the annual energy consumption in Kunming, which has a mild climate. The questionnaire surveys reveal building characteristics, housing appliances, household characteristics, indoor thermal environment and aspects of life style, during winter and summer seasons. The questionnaire analyses show that only 5% of the investigated households have air conditioning, and 12% have heating appliances. Most households use solar energy as a water heater energy source because the sunshine hours in Kunming are long. The energy consumption analyses show that the average annual energy consumption of households in Kunming reached 12.2 GJ, and cooking accounted for 5.3 GJ, which is the largest part. Most of the time in summer, the outdoor temperature is lower than living room and bedroom temperatures; thus, natural ventilation is a useful cooling method for households in Kunming. The absolute humidity in summer is about 11 g/kg, while in winter it is about 5 g/kg. The influence factor analyses show that building construction year, water heater type and annual income are important influential factors on annual energy consumption.

Yellow and colorless ancient glasses, which were once used to decorate the Temple of the Emerald Buddha, Bangkok, Thailand, around 150 years ago, are studied to unravel the long-lost glass-making recipes and manufacturing techniques. Analyses of chemical compositions, using synchrotron x-ray fluorescence (SRXRF), indicate that the Thai ancient glasses are soda lime silica glasses (60 % SiO2; 10 % Na2O; 10 % CaO) bearing lead oxide between 2-16 %. Iron (1.5-9.4 % Fe2O3) and manganese (1.7 % MnO) are present in larger abundance than the other 3 d transition metals detected (0.04-0.2 %). K-edge x-ray absorption near edge spectroscopy (XANES) and extended x-ray absorption fine structure spectroscopy (EXAFS) provide conclusive evidence on the oxidation states of Fe being 3+ and Mn being 2+ and on short-length tetrahedral structures around the cations. This suggests that iron is used as a yellow colorant with manganese as a decolorant. L 3-edge XANES results reveal the oxidation states of lead as 2+. The results from this work provide information crucial for replicating these decorative glasses for the future restoration of the Temple of the Emerald Buddha.

Since data encryption cannot prevent privacy invasions exploiting transmission pattern analysis and statistical inference, various methods based on fake data generation for concealing traffic patterns have been studied. In this paper, we describe an energy-efficient, light-weight, low-latency algorithm for creating dummy activities that are semantically similar to the observed phenomena. By using these cloaking activities, the amount of  fake data transmissions can be flexibly controlled to support a trade-off between energy efficiency and privacy protection. According to the experiments using real data collected from a smart home environment, our proposed method can extend the lifetime of the network by more than 2× compared to the previous methods in the literature. Furthermore, the activity cloaking method supports low latency transmission of real data while also significantly reducing the accuracy of the wireless snooping attacks.

Why this book on the Physics of Societal Issues? The subdivisions of physics - nuclear physics, particle physics, condensed-matter physics, biophysics - have their textbooks, while the subdivision of physics and society lacks an equation-oriented text on the physics of arms, energy and the environment. Physics of Societal Issues is intended for undergraduate and doctoral students who may work on applied topics, or who simply want to know why things are the way they are. Decisions guiding policies on nuclear arms, energy and the environment often seem mysterious and contradictory. What is the science behind the deployment of MIRVed ICBMs, the quest for space-based beam weapons, the fear of powerline EM fields, the wholesale acceptance of SUVs, the issues of climactic change, and the failure of the pre-embargo market to produce buildings and appliances that now save over 50 power plants? Physics of Societal Issues is three "mini-texts" in one: National Security (5 chapters): Weapons, offense, defense, verificat...

The MERCOSUL is a project for economic and market integration that embraces the geographic space confined within limits of Argentine, Brazil, Paraguay and Uruguay. The paper sets forth the previous studies about the instruments and mechanisms, in the most important aspects, that were responsible for MERCOSUL's foundation. All the stages, in the course of the integration process are mentioned, as well as the regional treaties and agreements (Montevideo Treaty, Cartagena Agreement, Centro-American Common Market, Caribbean Community (CARICON, Andean Pact, Assuncion Treaty). In the context, the author also makes careful considerations concerning nuclear energy environment, considering this matter not included in the MERCOSUL Agenda. Conclusions are drawn expecting that in the near future, the nuclear energy and nuclear energy environment should be assert emphatically and added in the MERCOSUL calendar, having the regional technical support, qualified human resources and the existing natural bilateral collaboration and cooperation. 10 refs

Household Energy Consumption Behaviour for Different Demographic Regions in Thailand from 2000 to 2010

Directory of Open Access Journals (Sweden)

Tharinya Supasa

2017-12-01

Full Text Available Since 1995, the residential sector has been a fast-growing energy consumption sector in Thailand. This sector contributes dramatically to the growth of Thailand’s electricity and oil demand. Our study analysed Thailand’s residential energy consumption characteristics and the seven underlying factors affecting the growth in energy use of five demographic regions using an energy input–output method. Embodied energy decomposition revealed that direct energy consumption accounted for approximately 30% of total residential energy use, whereas indirect energy consumption was at 70%. During the studied period, the growth in indirect energy use for all household groups was primarily the result of higher consumption of ‘commerce’, ‘air transport’, ‘manufacturing’, ‘food and beverages’ and ‘agriculture’ products. Moreover, each influencing driver contributes differently to each household’s growth in energy demand. The number of households was the leading factor that dominated the increases in residential energy use in the Greater Bangkok and Central regions. Growth in residential energy consumption in the Northern, Northeastern and Southern regions was strongly dominated by changes in income per capita. Consumption structure and using energy-efficient products had a moderate impact on all regions’ energy consumption. Thus, our findings provide additional energy-saving strategies to restrain further growth in residential energy demand.

DEEP-SaM - Energy-Efficient Provisioning Policies for Computing Environments

Bodenstein, Christian; Püschel, Tim; Hedwig, Markus; Neumann, Dirk

The cost of electricity for datacenters is a substantial operational cost that can and should be managed, not only for saving energy, but also due to the ecologic commitment inherent to power consumption. Often, pursuing this goal results in chronic underutilization of resources, a luxury most resource providers do not have in light of their corporate commitments. This work proposes, formalizes and numerically evaluates DEEP-Sam, for clearing provisioning markets, based on the maximization of welfare, subject to utility-level dependant energy costs and customer satisfaction levels. We focus specifically on linear power models, and the implications of the inherent fixed costs related to energy consumption of modern datacenters and cloud environments. We rigorously test the model by running multiple simulation scenarios and evaluate the results critically. We conclude with positive results and implications for long-term sustainable management of modern datacenters.

The paper takes an in-depth look at Heating Ventilation and Air Conditioning in a telecommunications environment. The focus is on developing energy conversion models for the cooling equipment installed in telecommunication exchanges. The models can be used for (1) evaluating the installed cooling capacity needed for a particular exchange and (2) assessing the financial implications, with reference to tariff structuring, of manipulating the elements that affect the required cooling load. Together, these will provide a powerful tool for evaluating cost-effective energy configurations, schedules and tariffs. (author)

Gaseous Criteria Pollutants in Bangkok Metropolitan Region, Thailand: Analysis, Issues and Management

Uttamang, P.; Aneja, V. P.; Hanna, A. F.

Analysis of gaseous criteria pollutants in Bangkok Metropolitan Region (BMR), Thailand, during 2010 to 2014 reveals that the hourly concentrations of CO, SO2 and NO2 were mostly below the National Ambient Air Quality Standards (NAAQs) of Thailand. However, the hourly concentrations of Ozone (O3) exceeded the Thailand NAAQs. The maximum concentrations of O3 were from 120 to 190 ppb. On average, the number of hourly O3 exceedances were from 1 to 60 hours a year depending on monitoring station locations. The exceedances were found during the dry season in both summer and winter. Inter-conversion between O3, NO and NO2 indicates the crossover point between species occur when the concentration of NOx ([NOx = NO + NO2]) is about 60 ppb. When [NOx] 60 ppb. The calculated photochemical reaction rate during photostationary state ranges from 0.12 to 1.22 min-1. Linear regression analysis between the concentrations of Ox ([Ox = O3 + NO2]) and NOx provides the role of local and regional contributions to Ox. Both the local and regional Ox contributions play an important role in the increase of [Ox] and those values were about double during O3 episodes ([O3] > 100 ppb). Ratio analysis suggests that the major contributors of primary pollutants over BMR are mobile sources (CO/NOx = 19.8). However, this region may also be influenced by point sources, but they are not dominant. An analysis of the air quality showed that the air quality index (AQI) for BMR was predominantly between good to moderate; however, during episode conditions in the region, unhealthy O3 categories were also observed.

Requirements of Integrated Design Teams While Evaluating Advanced Energy Retrofit Design Options in Immersive Virtual Environments

Directory of Open Access Journals (Sweden)

Xue Yang

2015-12-01

Full Text Available One of the significant ways to save energy use in buildings is to implement advanced energy retrofits in existing buildings. Improving energy performance of buildings through advanced energy retrofitting requires a clear understanding of the cost and energy implications of design alternatives from various engineering disciplines when different retrofit options are considered. The communication of retrofit design alternatives and their energy implications is essential in the decision-making process, as it affects the final retrofit selections and hence the energy efficiency of the retrofitted buildings. The objective of the research presented here was to identify a generic list of information requirements that are needed to be shared and collectively analyzed by integrated design teams during advanced energy retrofit design review meetings held in immersive settings. While identifying such requirements, the authors used an immersive environment based iterative requirements elicitation approach. The technology was used as a means to better identify the information requirements of integrated design teams to be analyzed as a group. This paper provides findings on information requirements of integrated design teams when evaluating retrofit options in immersive virtual environments. The information requirements were identified through interactions with sixteen experts in design and energy modeling domain, and validated with another group of participants consisting of six design experts who were experienced in integrated design processes. Industry practitioners can use the findings in deciding on what information to share with integrated design team members during design review meetings that utilize immersive virtual environments.

Essays on economic development, energy demand, and the environment

Medlock, Kenneth Barry, III

The rapid expansion of industry at the outset of economic development and the subsequent growth of the transportation and residential and commercial sectors dictate both the rate at which energy demand increases and the composition of primary fuel sources used to meet secondary requirements. Each of these factors each has an impact on the pollution problems that nations may face. Growth in consumer wealth, however, appears to eventually lead to a shift in priorities. In particular, the importance of the environment begins to take precedent over the acquisition of goods. Accordingly, cleaner energy alternatives are sought out. The approach taken here is to determine the energy profile of an average nation, and apply those results to a model of economic growth. Dematerialization of production and saturation of consumer bundles results in declining rates of growth of energy demand in broadly defined end-use sectors. The effects of technological change in fossil fuel efficiency, fossil fuel recovery, and 'backstop' energy resources on economic growth and the emissions of carbon dioxide are then analyzed. A central planner is assumed to optimize the consumption of goods and services subject to capital and resource constraints. Slight perturbations in the parameters are used to determine their local elasticities with respect to different endogenous variables, and give an indication of the effects of changes in the various assumptions.

RENEWABLE ENERGY, A KEY TO INTEGRATING COMPETITIVE POLICIES WITH ADVANCED ENVIRONMENT PROTECTION STRATEGIES

Directory of Open Access Journals (Sweden)

Cinade Lucian Ovidiu

2011-12-01

Full Text Available Development of competitive policies and improvement of environment protection strategies are two basic trends of the development of the European Unique Market. Energy, also known as 'industry bread', is basic product and strategic resource, where energy industry plays an obvious role in the economic and social development of any community. Traditional energy production is marred by three major drawbacks: it generates negative externalities by polluting; it is totally in the hands of the producers; hence, prices rise at their will, of fossil fuels such as oil and gas. Present study focuses on electric energy industry, yet bearing over the whole length of the chain producer-to-end-consumer, thus revealed as particularly complex. The question is do alternative energy sources meet the prerequisite of market being competitive meanwhile environment protection being highly observed. We identify limits in point, of the energy market; effects of market liberalization; entry barriers; interchangeability level of energy sources; active forces on the energy market. Competitive rivalry has been expressed as per market micro-economic analysis, based on Michael Porter's 5-forces model. It will thus be noticed that, morphologically, competition evolution depends firstly on the market type. For the time being, the consumer on the energy market stays captive, for various reasons such as: legislation; limits of energy transfer infrastructure; scarcity of resources; resources availability imbalance; no integrative strategy available, of renewable energy resources usage. Energy availability is vital for human society to function. Comparative advantages of renewable energy resources are twofold, as manifested: in terms of economics, i.e. improving competition by substitute products entered at the same time as new producers enter market; and in terms of ecology, by reducing CO2 emissions. As to energy production technology and transfer, the complementary nature will

When the future society of Asian countries is considered, three points of view have to be taken into account. As to energy security, the rate of oil self-supply in this region, which is 45% now, is expected to decrease, and oil import will be required. As to environmental protection, the increase of energy consumption results in the increase of pollutant emission which causes acid rain, global warming and so on. Economic development involves the expansion of energy consumption, the lowering of energy supply stability, and the increase of harmful gas emission. It partly depends on policy administration whether the three Es described above can be brought into well balanced harmony. In Asia, it is essential to transfer technologies from industrialized nations to developing countries. The problems of sulfur oxides and carbon dioxide are discussed. The harmonization of the three Es should be carried out at the regional level of whole Asia through international cooperation. The dependence on coal in total energy demand is as high as 60% in East Asia. Long term energy supply/demand outlooks for East Asian countries and the positioning of coal, and coal-related environmental measures are reported. (K.I.)

Environment and energy in Iceland: A comparative analysis of values and impacts

Thorhallsdottir, Thora Ellen

Within an Icelandic framework plan for energy, environmental values and impacts were estimated in multicriteria analyses for 19 hydroelectric and 22 geothermal developments. Four natural environment classes were defined (geology + hydrology, species, ecosystems + soils, landscape + wilderness) with cultural heritage as the fifth class. Values and impacts were assessed through 6 agglomerated attributes: richness/diversity, rarity, size/continuity/pristineness, information/symbolic value, international responsibility and visual value. The project offers a unique opportunity for comparing environmental values and impacts within a large sample of sites and energy alternatives treated within a common methodological framework. Total values were higher in hydroelectric than in geothermal areas. Hydroelectric areas scored high for cultural heritage (particularly in rarity and information value), landscape and wilderness. Geothermal areas had high bedrock and hydrological diversity and information values, and a high landscape visual value but little cultural heritage. High values were correlated among some classes of the natural environment, all of which are likely to reflect functional relationships. In contrast, cultural heritage values were not related to natural environment values. Overall, landscape and wilderness had the highest mean value and were also most affected by energy development. Over 40% of the hydroelectric development had a predicted mean impact value of > 4 (out of a maximum of 10), compared with 10% of the geothermal projects. Excluding two outsized hydropower options, there was a significant correlation between plant capacity and impact on geology and hydrology but not with other environmental variables

The impact of pollution at the different stages of exploitation of the primary energy sources is examined. According to Holdren, the social and environmental constraints much more than fuel supply will be the factor limiting the energy utilization rate for the next hundred years. Energy sources can be divided on one hand in non-renewable raw materials (coal, oil, natural gas, fissile and fusion materials) and, on the other hand, in renewable sources (hydraulic, solar, geothermal, wind). With regard to the appraisal of the environmental effects, the different steps of the fuel cycle have been considered: production or extraction, transport, treatment (enrichment, refining, purification etc.). The radiation dose rate from airborne releases of radionuclides are compared for geothermal, coal-fired and nuclear power plants

The surface energy partitioning in Arctic terrestrial and marine areas is a crucial process, regulating snow, glacier ice and sea ice melt, and permafrost thaw, as well as modulating Earth's climate on both local, regional, and eventually, global scales. The Arctic region has warmed approximately twice as much as the global average, due to a number of feedback mechanisms related to energy partitioning, most importantly the snow and ice-albedo feedback. However, direct measurements of surface energy budgets in the Arctic are scarce, especially for the cold and dark winter period and over transects going from the ice sheet and glaciers to the sea. This study aims to describe annual cycles of the surface energy budget from various surface types in Arctic Greenland; e.g. glacier, snow, wet and dry tundra and sea ice, based on data from a number of measurement locations across coastal Greenland related to the Greenland Ecosystem Monitoring (GEM) program, including Station Nord/Kronprins Christians Land, Zackenberg/Daneborg, Disko, Qaanaq, Nuuk/Kobbefjord and Upernaviarsuk. Based on the available time series, we will analyze the sensitivity of the energy balance partitioning to variations in meteorological conditions (temperature, cloudiness, precipitation). Such analysis would allow for a quantification of the spatial variation in the energy exchange in aforementioned Arctic environments. Furthermore, this study will identify uncertainties and knowledge gaps in Arctic energy budgets and related climate feedback effects.

In this interview, Dr. Barry Commoner discusses his analysis of energy problems as a function of the Second Law of Thermodynamics, i.e., that energy is necessary in order to perform work. As outlined in his book The Poverty of Power, a good thermodynamic approach matches the amount of energy expended with the task to be done. Electric transport is more energy efficient than private automobiles and illustrates how capital is wasted and social harm done to increase private profit. Inefficient energy use is the result of basing conservation efforts on the First rather than the Second Law. Commoner advocates social changes that give society more control over the means of production and the way resources are used. He feels the relative merits of solar energy and breeder reactors should be debated and a choice made, preferably for solar, to make a gradual transition to renewable resources. (DCK)

The generation of dynamic high energy density plasmas in the pico- to nano-second time domain at high-energy laser facilities affords unprecedented nuclear science research possibilities. At the National Ignition Facility (NIF), the primary goal of inertial confinement fusion research has led to the synergistic development of a unique high brightness neutron source, sophisticated nuclear diagnostic instrumentation, and versatile experimental platforms. These novel experimental capabilities provide a new path to investigate nuclear processes and structural effects in the time, mass and energy density domains relevant to astrophysical phenomena in a unique terrestrial environment. Some immediate applications include neutron capture cross-section evaluation, fission fragment production, and ion energy loss measurement in electron-degenerate plasmas. More generally, the NIF conditions provide a singular environment to investigate the interplay of atomic and nuclear processes such as plasma screening effects upon thermonuclear reactivity. Achieving enhanced understanding of many of these effects will also significantly advance fusion energy research and challenge existing theoretical models.

Energy and environment: two long-term strategies (1992-2020)

Desprairies, P.

1993-01-01

The report presented by western Europe at the 1992 World Energy Conference is one of the eight studies that served as a basis for the Energy for the World of Tomorrow scope. It proposes two strategic options for the period 1992-2020, with the goal in mind of reconciling the rising energy demand, concomitant with economic growth, with the need to protect the environment and natural resources. A serious struggle is already being waged against local and regional pollution, and these should about be done away just after the turn of the century. It will take from one to five decades, however, before the risk of climatic change, or 'Greenhouse effect', can be evaluated. This may in fact turn out to be negligible, and does not as yet justify any further action than the expense of evaluating it, and a minimum-regret strategy to slow down carbon dioxide emissions. This would be done by improving energy efficiency and a reasonable development of natural gas and then, after the current pause, resumption of nuclear power in those areas where it is accepted. The second 'alternative' strategy would aim to reduce CO 2 emissions further, if ever the risk of climatic change is confirmed within ten years. This would call for serious efforts. Depending on the various scenarios that have been developed, primary energy consumption would increase only by 19 to 27% form now until the year 2020. Neither the energy supply perspectives nor the proven ecological risks would justify any hasty developments of renewable energies. But a major scientific and technical research effort is still needed in this direction, in order to change gradually away from petroleum and gas in the course of the next 100 to 200 years. From now until 2020, fossil and nuclear fuels will continue to be the predominant western European energy resources. 9 figs

Taxing energy to improve the environment. Efficiency and distributional effects

1998-02-01

The effects of environmental tax policy in a dynamic overlapping-generations model of a small open economy with environmental quality incorporated as a durable consumption good have been studied. Raising the energy tax may deliver an efficiency gain if agents care enough about the environment. The benefits are unevenly distributed across generations since capital ownership, and the capital loss induced by a tax increase, rises with age. A suitable egalitarian bond policy can be employed in order to ensure everybody gains to the same extent. With this additional instrument the optimal energy tax can be computed. The authors further considered a tax reform that simultaneously lowers labour taxation and raises the energy tax. This policy delivers qualitatively similar consequences as the first scenario, though all changes are less pronounced. A double dividend may appear soon after the reform but vanishes in the course of the transition. 22 refs

Transportation demands a large and increasing share of total energy consumption in Europe. At the same time many European countries are facing difficult decisions in achieving their long term environmental goals. Therefore energy policy, environmental policy and transport policy should be seen and discussed in a common perspective. In particular the relative contribution from the transport sector and the energy sector involves a number of important and difficult issues. The aim of the conference was to bring together economists, scientists, manufactures, energy planners, transport planners, and decision makers in order to discuss the importance of the transport sector in relation to energy demand and long term environmental goals. General conference sessions covered. Trends in Transport Energy Demand and Environmental constraints, Technological Development and New Transport Systems, Lifestyle Changes and the Transport Sector, Megacities: Solutions to the Transport and Air Pollution Problems, Effectiveness of Public Policies, Transport and Energy sector, and Methods, Models and Data. The conference took place at Hotel Marienlyst, Elsinore, Denmark and attracted wide interest. The participants represented 14 different countries covering international organisations, ministries, universities, research centres, consulting firms, industry etc. (EG)

The use of economic forecasts in Danish economic policy, with special emphasis on energy and the environment

Nielsen, Lise

1998-01-01

This article discusses the use of economic forecasts in Danish economic policy, with special emphasis on energy and the environment. Two different approaches have been used to forecast energy consumption and its effects on environment in Denmark and other countries. These are the macro economic and the technical approaches. The technical approach is based on technical expertise related to energy production and energy consumption, and the article asks whether the forecasts produced by this approach are superior to macro economic forecasts of energy consumption. This question is interesting because the implications for policy resulting from the two approaches seem to be different. The analysis may have relevance to other areas outside the main economic field. (au) 22 refs

It is difficult to control household energy consumption through regulation. From a policy standpoint, it is particularly challenging to identify the factors that influence people’s actions. Moreover, whatever these factors are, they are unlikely to uniformly span multiple cities in the Asian region. In this paper, we conduct a survey of energy-saving behavior to clarify the differences among such factors across five major Asian cities. The results from these surveys in Dalian, Chongqing, Fukuoka, Bangkok, and Ho Chi Minh indicate that global warming consciousness, environmental behavior, and social interaction significantly affect energy-saving behavior. Income and age also had weak positive effects on energy-saving behaviors. Social interaction was strongly linked to energy-saving behaviors, particularly in the rural areas of Dalian and Chongqing. This result indicates that community-based activities impact energy-saving behaviors. - Highlights: ► We conduct a survey of energy saving behavior in household in major Asian cities. ► We identify the factors that influence people's actions. ► Global warming consciousness and social interaction affect people behavior. ► This indicates community-based activities impact energy-saving behaviors in Asia.

The research results found that there are nine current problems that need to be overcome in order to develop desirable characteristics for youths in schools. There are additionally eight desirable characteristics that need to be developed among youths, based on the statement of the Office of the Basic Education Commission. The investigation found that families, social media, community and religious leaders and schools all have an important role in promoting or creating desirable characteristics for youths. The content analysis found that all but one piece of heritable literature analysed contained content according to the eight desirable characteristics for youths. The handbook developed from the four pieces of heritable literature could be divided into four books for each piece of literature, which can be used as classroom teaching materials to create desirable characteristics for youths.

This final report for the Swiss Federal Office of Energy (SFOE) examines the effects of a future liberalisation of the gas market in Switzerland. The report first examines the current situation of the gas supply industry in Switzerland. The contents of European Union Guidelines are described and their implementation in Switzerland is discussed. Experience already gained in other countries is looked at, including market opening already implemented in the USA and Great Britain. The effect of market-opening on gas prices is discussed; the various components of the gas price are examined and comparisons are made with international figures. The pressure of competition on the individual sectors of the gas industry are looked at and the perspectives in the gas purchasing market are examined. The report presents basic scenarios developed from these considerations. Further effects resulting from a market opening are discussed, including those on the structure of the gas industry, its participants, electricity generation, energy use and the environment, consumers in general, security of supply and the national economy. Possible compensatory measures are discussed and factors for increasing efficiency and the promotion of a competitive environment are discussed. In the appendix, two price scenarios are presented

An integrated econometric model consisting of macroeconomic sub-model, energy sub-model and environment sub-model was developed and used to perform a long-term simulation study for China. In the coming 30 years, the potential of GDP growth will be around 7% annually and the continuation of rapid economic growth could result in insurmountable difficulties for energy security, air protection, and CO 2 emission reductions. For the sustainable development, more comprehensive measures should be adopted, including improvements in energy efficiency, more rapid energy switching from coal to natural gas and renewable energy sources, imposing carbon tax, development of clean coal technology, establishment of strategic petroleum stockpiling, enforcement of air protection, etc

This paper introduces the Global Resource Balance Table (GRBT), which is an extension of the energy balance tables that expresses the relationships between energy, materials and the environment. The material division of the GRBT includes steel, cement, paper, wood and grain. In contrast, the environmental division of the GRBT includes oxygen, CO 2 and methane. The transaction division rows in the GRBT include production, conversion, end use and stock. Each cell of the GRBT contains the quantities of the respective resources that were generated or consumed. The relationships between the cells were constructed from the laws of conservation of the materials and energy. We constructed a GRBT for 2007 and discussed the increasing air temperature due to waste heat and the CO 2 equivalent from human breathing. The GRBT is a comprehensive integrated table that represents the resources that are consumed by human activities and is useful for energy and environmental studies. - Highlights: • We extended energy balance table and introduced Global Resource Balance Table. • It shows relationships between energy, materials and the environment. • The material division includes steel, cement, paper, wood and grain. • The environmental division includes oxygen, CO 2 and methane. • We discussed on waste heat and CO 2 emission by human breathing

Benzene, toluene, ethylbenzene and xylenes (BTEX) and carbonyl compounds (CCs) are recognized traffic-related air pollutants in urban environments and are the focus of this study. In Bangkok, the BTEX and CC concentrations in both ambient air and personal exposure samples were studied during two periods (April-May and August-September 2014) at four different sampling sites around the Pathumwan District (three intersections and one T-junction). Traffic policemen, representing the high-exposure group for these toxic air pollutants, were observed, and the health risk to these workers was evaluated. Toluene was the predominant aromatic compound in the ambient and personal exposure samples. The maximum average ambient concentration of BTEX was 2968.96 μg/m3. Formaldehyde and acetaldehyde were the most abundant CCs at all of the sampling sites, with the greatest mean concentrations of these substances being 21.50 μg/m3 and 64.82 μg/m3, respectively. In the personal exposure samples, the highest levels of BTEX, formaldehyde and acetaldehyde concentrations were 2231.85 μg/m3, 10.61 μg/m3, and 16.03 μg/m3, respectively. In terms of risk assessment, benzene posed the greatest cancer risk (at the 95% CI), followed by toluene, acetaldehyde and formaldehyde (1.15E-02, 5.14E-03, 2.84E-04, and 2.52E-04, respectively). Three risk factors were investigated to reduce the total cancer risk levels: reducing the chemical concentration, exposure time and exposure duration. The use of a mask (chemical concentration) was the best way to reduce the risk to traffic police. However, the risk value of benzene (average 1.57E-05) was still higher than an acceptable value when using a mask.

As medical technology evolves and patient needs increase, the need for well-trained and highly professional medical physicists (MPs) becomes even more urgent. The roles and responsibilities of MPs in various departments within the hospital are diverse and demanding. It is obvious that training, continuing education and professional development of MPs have become essential. One of the ways for an MP to advance his or her knowledge is to participate in conferences and congresses. Last year, the 22nd International Conference of Medical Physics (ICMP 2016) took place in Bangkok, Thailand. The event attracted 584 delegates with most of the participants coming from Asia. It attracted also delegates from 42 countries. The largest delegations were from Thailand, Japan and South Korea. ICMP 2016 included 367 oral presentations and e-posters, most of these being in the fields of Radiation Therapy, Medical Imaging and Radiation Safety. All abstracts were published as an e-book of Abstracts in a supplement to the official IOMP Journal. Many companies had exhibition stands at ICMP2016, thus allowing the participants to see the latest developments in the medical physics-related industry. The conference included 42 mini-symposia, part of the first "IOMP School" activity, covering various topics of importance for the profession and this special issue follows from the success of the conference.

Makowski, D R; Napieralski, A; Swiercz, B P

2005-01-01

This paper reports a novel NVRAM-based neutron dose monitor (REM counter). The principle of this device is based on the radiation effect initiating the Single Event Upset SEU in high density microelectronic memories. Several batches of Non-Volatile memories from different manufactures were examined in various radiation environments, i.e. 241Am-Be (alpha,n) and Linear accelerators produced radiation fields. A suitable moderator was used to enhance the detector sensitivity. Further experiments were carried out in Linear Accelerators: Linac II, TTF2 and Beam Loss Environment of various Experimental Facilities at DESY Research Centre in Hamburg. A separate batch of SRAM was irradiated with 60Co-gamma rays up to a dose of about 60 Gy. No Single Event Upset (SEU) was registered. This validates, that gamma radiation has a negligible effect to trigger SEU in the SRAM. The proposed detector could be ideal for a neutron dose measurement produced by a high-energy electron linac, including synchrotron and Free Electron L...

Trends of world energy consumption and possibilities of environment protective power generation

International Nuclear Information System (INIS)

Frischengruber, K.

1991-01-01

The population of the world will duplicate within the next three to four decades. The primary energy consumption will increase accordingly. Considering the limited reach of our fossil energy resources and their negative impact on the global climate, alternative strategies for the power generation have to be developed. The contribution of the renewable energy sources will be important, but not sufficient, due to their high generation costs. The nuclear power, which already today participates essentially in the energy supply, will remain one of the most important options for environment protecting energy generation. Especially for the developing countries, which -in general- have currently a not covered energy demand, the build up of reasonable energy generation structures means enormous volumes of investments, which can only be financed with the assistance of the industrialized countries. Those, on the other hand, have to economize their energy consumption and have to undertake any effort in continuing with the development of clean, safe and competitive renewable resources. To provide increasing world population with sufficient energy and at the same time to reduce CO 2 emissions is one of the biggest challenges that mankind has ever faced. (Author)

Changes in the Global Energy System: Implications for China's International Strategic Environment

Directory of Open Access Journals (Sweden)

Zhang Chi

2015-12-01

Full Text Available This article briefly discusses major reasons for the slump of international oil prices and provides a prediction for the future development of international oil prices, before analyzing the three factors leading to significant changes of the global energy system, namely the eastward shift of the world energy consumption centre, the emergence of the United States as a major oil producer and the dramatic waning of the Organization of Petroleum Exporting Countries’ (OPEC influence. These factors and developments are shaping a new order of the global energy strategic landscape and exerting profound influence on China’s international strategic environment. In the foreseeable future, these changes of the global energy system would bring China more uncertainties regarding the country’s oil imports from the Middle East, more strategic pressure from the United States, while promoting China’s leverage on the global energy system and international relations.

2015-10-01

In this article, we are investigating excitation energy transfer (EET) in a basic unit cell of light-harvesting complex II (LH2), named a LH2-type trimer. Calculation of energy transfer efficiency (ETE) in the framework of non-Markovian environment is also implemented. With these achievements, we theoretically predict the environment-assisted quantum critical effect, where ETE exhibits a sudden change at the critical point of quantum phase transition (QPT) for the LH2-type trimer. It is found that highly efficient EET with nearly unit efficiency may occur in the vicinity of the critical point of QPT.

Nuclear energy, radiation and environment

Over the past few decades, energy has been the subject of much debate. Energy is the backbone of technology and economic development. Today, most machines run on electricity and they are needed to make anything and everything. Hence, our energy requirements have spiraled in the years following the industrial revolution. This rapid increase in use of energy has created problems of demand and supply in addition to the environmental consciousness which picked momentum in last decades of 20 th century. The impending crisis the world over due to overuse of nonrenewable energy sources to reduce this gap shall soon lead to a situation for all concerned to take a prudent decision to tap other sources of energy, including relatively new renewable sources. Future economic growth crucially depends on the long-term availability of energy from sources that are affordable, accessible and environmentally friendly. The drive for more energy has had the happy consequences of spawning new technologies and improving earlier ones. Emphasis on renewable sources has resulted in viable harnessing of solar, wind and tidal energies. Even though these sources offer relatively clean energy, their potential to supply reliable energy in large scale in an economically viable way is limited. Nuclear energy offers a major source of commercial energy, which is economic, reliable and environmentally benign

Environment sensitive embedding energies of impurities, and grain boundary stability in tantalum

International Nuclear Information System (INIS)

Krasko, G.L.

1996-01-01

Metalloid impurities have a very low solubility in tantalum, and therefore prefer to segregate at the grain boundaries (GBs). In order to analyze the energetics of the impurities on the tantalum GB, the LMTO calculations were performed on a simple 8-atom supercell emulating a typical (capped trigonal prism) GB environment. The so-called environment-sensitive embedding energies were calculated for hydrogen, boron, carbon, nitrogen, oxygen, phosphorus, and sulphur, as a function of the electron charge density due to the host atoms at the impurity site. The calculations showed that, at the electron density typical of a GB, carbon has the lowest energy (followed by Nitrogen and Boron) and thus would compete with the other impurities for the site on the GB, tending to displace them from the GB. The above energies were then used in a modified Finnis-Sinclair embedded atom approach for calculating the cohesive energies and the equilibrium interplanar distances in the vicinity of a (111) Σ3 tilt GB plane, both for the clean GB and that with an impurity. These distances were found to oscillate, returning to the value corresponding to the equilibrium spacing between (111) planes in bulk BCC tantalum by the 10th--12th plane off the GB. Carbon, nitrogen and boron somewhat dampen the deformation wave (making the oscillations less than in the clean GB), while oxygen, phosphorus and sulphur result in an increase of the oscillations. The cohesive energies follow the same trend, the GB with carbon being the most stable. Thus, carbon, nitrogen and boron may be thought of as being cohesion enhancers, while oxygen, phosphorus and sulphur result in decohesion effects

Evaluation of economical introduction of nuclear fusion based on a long-term world energy and environment model

Debates about whether or not to invest heavily in nuclear fusion as a future innovative energy option have been made within the context of energy technology development strategies. The time frame by which nuclear fusion could become competitive in the energy market has not been adequately studied, nor has roles of the nuclear fusion in energy systems and the environment. The present study has two objectives. One is to reveal the conditions under which nuclear fusion could be introduced economically (hereafter, we refer to such introductory conditions as breakeven prices) in future energy systems. The other objective is to evaluate the future roles of nuclear fusion in energy systems and in the environment. Here we chose two roles that nuclear fusion will take on when breakeven prices are achieved: i) reduction of annual global total energy systems cost, and ii) mitigation of carbon tax (shadow price of carbon) under CO 2 constraints. Future uncertainties are key issues in evaluating nuclear fusion. Here we treated the following uncertainties: energy demand scenarios, introduction time frame for nuclear fusion, capacity projections of nuclear fusion, CO 2 target in 2100. From our investigations, we conclude that the presently designed nuclear fusion reactors may be ready for economical introduction into energy systems beginning around 2050-2060, and we can confirm that the favorable introduction of the reactors would reduce both the annual energy systems cost and the carbon tax (the shadow price of carbon) under a CO 2 concentration constraint; however, latter introduction of them decreases the cost and the tax less than five times. Earlier introduction of nuclear fusion reactors are desirable for energy systems and environment. (author)
