The Pneumoconiosis Field Research (PFR) programme was established in the 1950s, to evaluate effects of coal mining exposures on the health and mortality of British coal workers. Surveys of working miners were carried out at 5-yearly intervals, initially in 24 collieries but later concentrating on 10, collecting detailed work histories and health information for each recruit. Here we report on cause-specific mortality in a cohort of almost 18,000 men from 10 British collieries, followed up for periods up to 47 years, yielding over 516,000 life-years of follow-up. External analyses compared cause-specific death rates in the cohort to those of the population of the regions in which the collieries were situated, using Standardised Mortality Ratios (SMRs). The causes investigated included lung cancer, stomach cancer, non-malignant respiratory disorders and cardiovascular disorders. SMRs showed evidence of an initial healthy worker effect diminishing over time. Several causes, including non-malignant respiratory disease and lung cancer, showed a significant deficit of mortality at the start of the study period with an excess in the latter part of the follow-up period. In these results, effects of working conditions are likely to be confounded with smoking habits. Overall, we believe our results may be generalised to the British coal industry since nationalisation.

The purpose of this study was to determine the effects of foot reflexology on fatigue and insomnia in patients suffering from coal workers' pneumoconiosis. This study was a quasi-experimental study of pre-test and post-test design in a non-equivalent control group. The subjects of this study consisted of both the experimental group of twenty-nine and the control group of thirty coal workers' pneumoconiosis patients. Data was collected from December 10, 2002 to February 15, 2003. Foot reflexology was performed for 60 minutes twice a week through five weeks in the experimental group, but none in the control group. To evaluate the effects of foot reflexology, the scores of fatigue and insomnia were measured before and after the experiment in both groups. Fatigue was evaluated by Fatigue Symptoms Inventory. Insomnia was measured with the visual analogue scale (VAS). Data of this experiment was analyzed by Chi-square test, t-test, unpaired t-test and Repeated Measures ANOVA with the SAS Program. The scores of fatigue and insomnia decreased in the experimental group but not in the control group. There was a significant difference of fatigue and insomnia between the two groups. It is suggested that foot reflexology might have beneficial effects on reducing fatigue and insomnia in patients suffering from coal workers' pneumoconiosis, and can be recommended as a nursing intervention program for patients with coal workers' pneumoconiosis.

Coal worker's pneumoconiosis (CWP) results from coal mine dust inhalation. The paper reports the presence of a chronic interstitial pneumonia (CIP) with honeycombing in 38 cases of coal miners, with or without CWP. The 38 patients were selected on the basis of clinical criteria which are unusual in CWP, i.e. fine inspiratory crackles and severe dyspnea. There were 37 men and one woman; mean age was 67.5 {+-} 9.1 years. Thirty-two were smokers. Duration of exposure was 26.7 {+-} 9.9 years. All the patients had clinical examination, chest radiography, computed tomography (CT), lung function, laboratory investigations, wedged fiberoptic bronchoscopy with bronchoalveolar lavage (BAL). In eight cases, lung specimens were obtained. Seventeen out of 38 had finger clubbing. 17 had radiological signs of CWP limited to the upper lobes or diffusely distributed. CT showed honeycombing (36 cases), and/or ground glass opacities (30 cases) with traction bronchiectasis (8 cases) predominant in the lower lobes. BAL analysis demonstrated an increased percentage of neutrophils (9.4% {+-} 6). Lung function showed a restrictive pattern associated with a decreased DLCO and hypoxemia. Lung specimens demonstrated in 2 cases a homogenous interstitial fibrosis of intra-alveolar septum with an accumulation of immune and inflammatory cells without temporal variation and with obvious honeycombing. The 6 other cases showed features of usual interstitial pneumonia. These cases, should alert other clinicians to a possible association between CIP with honeycombing and coal dust exposure, with or without associated CWP.

High-resolution computed tomography (HRCT) is more sensitive than chest X-ray (CXR) in the depiction of parenchymal abnormalities. The paper presents and compares CXR and HRCT findings in coal workers with and without early and low-grade coal worker's pneumoconiosis (CWP). 71 coal workers were enrolled in the study. HRCT's were graded according to Hosoda and Shida's Japanese classification. After grading, 67 workers with CXR profusion 0/0-2/2 were included in the study. Four patients with major opacity were excluded. Profusion 0/1 to 1/1 cases were accepted as early and profusion and 2/2 cases as low-grade pneumoconiosis. Discordance rate was found to be higher in the early pneumoconiosis cases with negative CXR than low-grade pneumoconiosis (60, 36 and 8%, respectively). When coal miners with normal CXR were evaluated by HRCT, six out of 10 cases were diagnosed as positive. In low-grade pneumoconiosis group, the number of patients with positive CXR but negative HRCT were low in comparison to patients with CXR negative and early pneumoconiosis findings. Most of the CXR category 0 patients (10/16) were diagnosed as category 1 by HRCT. Eleven cases diagnosed as CXR category 1 were diagnosed as category 0 (7/11) and category 2 (4/11) by HRCT. In CXR category 2 (eight cases), there were four cases diagnosed as category 1 by HRCT. Overall, discordance between CXR and HRCT was high, especially for CXR negative and early pneumoconiosis cases. The role of CXR in screening coal workers to detect early pneumoconiosis findings should be questioned. The authors suggest using HRCT as a standard screening method instead of CXR to distinguish between normal and early pneumoconiosis.

Full Text Available Abstract Background Few studies of miners have been carried out in African countries; most are from South Africa, where the working conditions are assumed to be better than in the rest of Africa. Several studies have focused on respiratory disorders among miners, but development workers responsible for creating underground road ways have not been studied explicitly. This is the first study assessing the associations between exposure to dust and quartz and respiratory symptoms among coal mine workers in a manually operated coal mine in Tanzania, focusing on development workers, as they have the highest exposure to coal dust. Methods A cross-sectional study was carried out among 250 production workers from a coal mine. Interviews were performed using modified standardized questionnaires to elicit information on occupational history, demographics, smoking habits and acute and chronic respiratory symptoms. The relationships between current dust exposure as well as cumulative respirable dust and quartz and symptoms were studied by group comparisons as well as logistic regression. Results Workers from the development group had the highest dust exposure, with arithmetic mean of 10.3 mg/m3 for current respirable dust and 1.268 mg/m3 for quartz. Analogous exposure results for mine workers were 0.66 mg/m3 and 0.03 mg/m3, respectively; and for other development workers were 0.88 mg/m3 and 0.10 mg/m3, respectively. The workers from the development section had significantly higher prevalence of the acute symptoms of dry cough (45.7%, breathlessness (34.8% and blocked nose (23.9%. In addition, development workers had significantly more chronic symptoms of breathlessness (17.0% than the mine workers (6.4% and the other production workers (2.4%. The highest decile of cumulative exposure to respirable dust was significantly associated with cough (OR = 2.91, 95% CI 1.06, 7.97 as were cumulative exposure to quartz and cough (OR = 2.87, CI 1.05, 7.88, compared with

Full Text Available Mother tongue education (or instruction plays quite a significant role in individual students’ success in both social and academic areas. A qualified mother tongue education is crucial in ensuring those students become successful adults in their later life and adopt their own culture and identities. From time to time, there might be students who have mother tongue medium education along with those who have other languages as the medium of instruction. Among those bilingual students there are children of Turkish citizens who immigrated to Western Europe as workers. Mother tongue education is a necessity for bilingual individuals to protect their identities, to adopt to the society they already live in and to learn the language used in that very society much more easily. This makes it more important for the bilingual Turkish children living in foreign countries to receive mother tongue education. In this vein, the attitudes of Turkish students, who live in England, towards the Turkish language class are examined. 105 Turkish students between 11 and 18 years enrolled in Wisdom and Namık Kemal Turkish School in the UK were requested to fill in a questionnaire. Based on their responses, their opinions about the Turkish language class were evaluated.

Full Text Available Noise influence takes one of the leading roles in the development of sensorineural hearing loss (SHL. At the same time professional deafness steadily occupies the 5th place in the structure of occupational diseases in Ukraine over the past few years. Of special importance is the problem of pre-clinical and early diagnosis of occupational hearing deterioration, in sense of timely prophylactic and rehabilitation measures in “risk group” workers. The objective research methods play an important role in the diagnosis of auditory analyzer state. Many scientific studies have shown the diagnostic effectiveness of method of otoacoustic emissions recording in the early diagnosis of lesions of receptor part of auditory analyzer. It is known that SHL of noise genesis largely affects the receptor part of the auditory analyzer, for which the OAE method has great practical diagnostic significance. Objective: to study informativity indicators of otoacoustic emission for the diagnosis of sensorineural hearing loss in various occupational groups of coal workers in Ukrainian mines. Materials and Methods: Auditory function of 87 workers of the coal industry (drifters, miners and longwall miners with different levels of industrial noise and hygienic conditions in their workplaces was: 28 studied drifters (group 1, 25 miners (group 2 and 34 longwall miners (group 3. Work experience in noise in these groups was 17,9±1,0; 23,1±1,0 and 22,2±2,0 accordingly. Noise ratio in drifters was 93,6±4,9 dBA, in miners – 92,9±5,5 dBA and in longwall miners – 86,5±6,04 dBA accordingly, while the maximum permitted level is 80 dBA. The research was conducted on the analyzing system "Eclipse" "Interacoustics" (Denmark. All patients underwent registratiov of the caused OAE at frequency distortion product (DPOAE at frequencies 1-6 kHz. The results were rated using variation statistics Student's test.

We aimed to estimate the economic losses currently caused by coal workers' pneumoconiosis (CWP) and, on the basis of these measurements, confirm the economic benefit of preventive measures. Our cohort study included 1,847 patients with CWP and 43,742 coal workers without CWP who were registered in the employment records of the Datong Coal Mine Group. We calculated the cumulative incidence rate of pneumoconiosis using the life-table method. We used the dose-response relationship between cumulative incidence density and cumulative dust exposure to predict the future trend in the incidence of CWP. We calculate the economic loss caused by CWP and economic effectiveness of CWP prevention by a step-wise model. The cumulative incidence rates of CWP in the tunneling, mining, combining, and helping cohorts were 58.7%, 28.1%, 21.7%, and 4.0%, respectively. The cumulative incidence rates increased gradually with increasing cumulative dust exposure (CDE). We predicted 4,300 new CWP cases, assuming the dust concentrations remained at the levels of 2011. If advanced dustproof equipment was adopted, 537 fewer people would be diagnosed with CWP. In all, losses of 1.207 billion Renminbi (RMB, official currency of China) would be prevented and 4,698.8 healthy life years would be gained. Investments in advanced dustproof equipment would be total 843 million RMB, according to our study; the ratio of investment to restored economic losses was 1:1.43. Controlling workplace dust concentrations is critical to reduce the onset of pneumoconiosis and to achieve economic benefits.

Coal dust causes lung diseases in occupational exposure. Reactive oxygen species have been implicated in the pathogenesis of its toxicity. In this study, serum enzymes, lipid profile and other biochemical values with oxidant/antioxidant status in whole blood and serum of central heating system workers (CHSW; the persons responsible for heating the apartment with coal) were determined to reflect the cell injury. Blood samples were obtained from CHSW (n = 25) and healthy individuals (n = 25). All values were measured in whole blood and serum. ANOVA was used for the estimation of statistical data. In the group of CHSW, creatinine, ferritin, alanin aminotransferase, aspartate aminotransferase, creatine phosphokinase, gamma glutamyl transferase, lactate dehydrogenase and glutathione reductase activities as well as triglyceride, very low density lipoprotein, protein carbonyl and malondialdehide were significantly higher, while transferrin, high density lipoprotein and catalase (CAT) activities were lower than the group of healthy individuals. This result is consistent with hypothesis that respirable coal dust generates lipid and protein oxidation and induces leakage of serum enzymes by cell damage. It also leads to imbalance in antioxidant defense system, lipid profile and other biochemical parameters.

Coal will be a dominant energy source in both developed and developing countries for at least the first half of the 21st century. Environmental problems associated with coal, before mining, during mining, in storage, during combustion, and postcombustion waste products are well known and are being addressed by ongoing research. The connection between potential environmental problems with human health is a fairly new field and requires the cooperation of both the geoscience and medical disciplines. Three research programs that illustrate this collaboration are described and used to present a range of human health problems that are potentially caused by coal. Domestic combustion of coal in China has, in some cases, severely affected human health. Both on a local and regional scale, human health has been adversely affected by coals containing arsenic, fluorine, selenium, and possibly, mercury. Balkan endemic nephropathy (BEN), an irreversible kidney disease of unknown origin, has been related to the proximity of Pliocene lignite deposits. The working hypothesis is that groundwater is leaching toxic organic compounds as it passes through the lignites and that these organics are then ingested by the local population contributing to this health problem. Human disease associated with coal mining mainly results from inhalation of particulate matter during the mining process. The disease is Coal Worker's Pneumoconiosis characterized by coal dust-induced lesions in the gas exchange regions of the lung; the coal worker's "black lung disease". ?? 2002 Elsevier Science B.V.

Coal mine workers are at risk for a range of chronic respiratory diseases including coal workers' pneumoconiosis, diffuse dust-related fibrosis, and chronic obstructive pulmonary disease. The purpose of this review is to describe coal mining processes and associated exposures to inform the diagnostic evaluation of miners with respiratory symptoms. Although rates of coal workers' pneumoconiosis declined after regulations were enacted in the 1970s, more recent data shows a reversal in this downward trend. Rapidly progressive pneumoconiosis with progressive massive fibrosis (complicated coal workers' pneumoconiosis) is being observed with increased frequency in United States coal miners, with histologic findings of silicosis and mixed-dust pneumoconiosis. There is increasing evidence of decline in lung function in individuals with pneumoconiosis. Multiple recent cohort studies suggest increased risk of lung cancer in coal miners. A detailed understanding of coal mining methods and processes allows clinicians to better evaluate and confirm chronic lung diseases caused by inhalational hazards in the mine atmosphere.

During the last decade, coal-based sponge iron plants, a highly polluted industry, have grown rapidly in Barjora, India. Understanding their workers' perception of health is essential in people-centered healthcare. The aim of the study was to assess their health-related quality-of-life (HRQoL), and to determine factors that independently predict their HRQoL. Cross-sectional study. Coal-based sponge iron plants in Barjora, India. 258 coal-based sponge iron plant workers. HRQoL was measured using the EuroQol-5D-5L. The response rate was 100%. Participants with problems in mobility, self-care, usual activities, pain/discomfort and anxiety/depression were 23.3%, 5.1%, 10.9%, 39.5% and 45.5%, respectively. 36.8% of participants reported health state 11111 (no problem in any EQ-5D dimension). The mean visual analogue scale (EQ-VAS) was 69.8 (18.5 SD). The odds of mobility problems decreased with age (OR 0.95, 95% CI 0.91 to 0.99, p=0.016), were lower in participants with presence/history of any respiratory disease (0.27, 0.13 to 0.55, pworkers (0.44, 0.22 to 0.89, p=0.021), manual workers (0.40, 0.16 to 0.99, p=0.047) and non-smokers (2.63, 1.27 to 5.46, p=0.009). The odds of pain/discomfort and anxiety/depression were lower in participants with any respiratory disease (0.44, 0.24 to 0.79, p=0.006; and 0.52, 0.29 to 0.92, p=0.026, respectively). The EQ-VAS was worse in manual participants (coefficient -6.91, 95% CI -12.40 to -1.41, p=0.014), with any respiratory disease (-8.13, -13.12 to -3.13, p=0.002), alcohol drinkers (-4.81, -9.47 to -0.15, p=0.043), literates (7.70, 0.97 to 14.43, p=0.025) and Hindus (13.41, 2.62 to 24.20, p=0.015). Many coal-based sponge iron plant workers in Barjora have problems in their HRQoL, and the predictors of different aspects of HRQoL were identified. The study findings could be taken into consideration in future interventional studies aimed at improving the HRQoL of these workers. Published by the BMJ Publishing Group Limited. For

During the past decade, coal-based sponge iron plants, a highly polluted industry, have grown rapidly in Barjora, India. The toxic effects of particulate matters and gaseous pollutants include various respiratory diseases. Understanding workers' perception of respiratory health is essential in people-centred healthcare. The aim of the study was to assess their respiratory health status and to determine its predictors. Cross-sectional study. Coal-based sponge iron plants in Barjora, India. 258 coal-based sponge iron plant workers. Respiratory health status was measured using the St. George's respiratory questionnaire (SGRQ) total score. 100 and 0 represent the worst and best possible respiratory health status, respectively. The two-part model (frequency (any worse respiratory health status) and severity (amount of worse respiratory health status)) was developed for the score, as the data were positively skewed with many zeros. The mean (SD) SGRQ total score was 7.7 (14.5), the median (IQR) was 0.9 (9.0), and the observed range was 0-86.6. The best possible SGRQ total score was reported by 46.9% of workers. Independent predictors of worse respiratory health status were cleaner domestic cooking fuel (coefficient -0.76, 95% CI -1.46 to -0.06, p=0.034) and personal history of any respiratory disease (1.76, 1.04 to 2.47, pworkers in Barjora have the best possible respiratory health status. The predictors of worse respiratory health status were identified. The study findings could be taken into consideration in future interventional studies aimed at improving the respiratory health status of these workers. Published by the BMJ Publishing Group Limited.

To protect the health of active U.S. underground coal miners, the National Institute for Occupational Safety and Health (NIOSH) has a mandate to carry out surveillance for coal workers' pneumoconiosis, commonly known as Black Lung (PHS 2001). This is accomplished by reviewing chest x-ray films obtained from miners at approximately 5-year intervals in approved x-ray acquisition facilities around the country. Currently, digital chest images are not accepted. Because most chest x-rays are now obtained in digital format, NIOSH is redesigning the surveillance program to accept and manage digital x-rays. This paper highlights the functional and security requirements for a digital image management system for a surveillance program. It also identifies the operational differences between a digital imaging surveillance network and a clinical Picture Archiving Communication Systems (PACS) or teleradiology system.

To analyze the potential of MR to distinguish lung cancer from progressive massive fibrosis (PMF) in patients with coal worker's pneumoconiosis. The study consisted of 9 patients with pathologically proven lung cancer and 26 PMFs in 17 patients. All the patients had radiologic evidence of pneumoconiosis. T1-weighted FLASH images were obtained before and 0.5, 1, 2, 3, 4, 5, 7.5, 10, 12.5, and 15 minutes after injection of Gd-DTPA. T2-weighted fast spin-echo images were obtained. The imaging findings were evaluated for enhancement time curve, contrast uptake equivalent (CE), and enhancement factor (EF). On T1WI, there was no significant signal intensity difference between lung cancer and PMF. On T2WI, all lung cancer showed high signal intensity, as opposed to all PMFs which showed low signal intensity except for one PMF. Only one PMF showed high signal intensity on T2WI. For the dynamic contrast study, lung cancer showed faster and slightly stronger enhancement than PMFs. For a delayed image, most of the lung cancers (78%) showed washout, as opposed to a plateau in most of PMFs (73%) (p=0.0153). However, no difference was detected between the EFmax of lung cancer and PMFs (p=0.349). MR is potentially a useful tool in distinguishing lung cancer from PMFs in patients with coal worker's pneumoconiosis

Biering-Sorensen test is an isometric back endurance test. Biering-Sorensen test scores have varied in different cultural and occupational groups. The aims of this study were to collect normative data on Biering-Sorensen holding times, to determine the discriminative ability of the Biering-Sorensen test in Turkish coal miners, and to examine the association between Biering-Sorensen test result and functional disability. One hundred and fifty male coal miners participated in this study. Trunk extensor muscle strength was measured using the Biering-Sorensen test. Oswestry disability index was used to measure the functional disability level of low back pain. The mean Biering-Sorensen holding time for the total subject group was 107.3 {+-} 22.5 s. The mean time of Biering-Sorensen test of the subjects with and without low back pain were 99.9 {+-} 19.8 and 128.6 {+-} 15.2 s, respectively. The difference between the subjects with and without low back pain was statistically significant (p < 0.001). There was a statistically significant negative correlation between Oswestry functional disability score and Biering-Sorensen holding time (R = -0.824, p < 0.001). Turkish coal miners have low mean back extensor endurance holding times. Biering-Sorensen test had a good discriminative ability in our study group. Trunk muscle strength has a significant effect on the disability level of low back pain. Thus trunk muscle endurance training exercise therapy may be effective for the reduction of disability in patients with low back pain.

To produce ashless coal extracts, three Turkish coals were extracted with N-methyl-2-pyrrolidinone (NMP), NMP/ethylenediamine (EDA) (17/1, vol/vol) mixture and NMP/tetralin (9/1, vol/vol) mixture through thermal extraction and microwave extraction. Solvent extraction by microwave irradiation (MI) was found to be more effective than that by thermal extraction. Extraction yield of coals in NMP enhanced by addition of a little EDA, but tetralin addition showed variances according to extraction method used. While tetralin addition caused a decrease in the thermal extraction yield, it increased the yield of the extraction by MI. Following the extraction, the solid extracts were produced with ash content ranging from 0.11% to 1.1%. Ash content of solid extract obtained from microwave extraction are less than ash contents of solid extracts obtained from thermal extraction. 34 refs., 7 figs., 5 tabs.

We aimed to estimate the economic losses currently caused by coal workers’ pneumoconiosis (CWP) and, on the basis of these measurements, confirm the economic benefit of preventive measures. Our cohort study included 1,847 patients with CWP and 43,742 coal workers without CWP who were registered in the employment records of the Datong Coal Mine Group. We calculated the cumulative incidence rate of pneumoconiosis using the life-table method. We used the dose-response relationship between cumulative incidence density and cumulative dust exposure to predict the future trend in the incidence of CWP. We calculate the economic loss caused by CWP and economic effectiveness of CWP prevention by a step-wise model. The cumulative incidence rates of CWP in the tunneling, mining, combining, and helping cohorts were 58.7%, 28.1%, 21.7%, and 4.0%, respectively. The cumulative incidence rates increased gradually with increasing cumulative dust exposure (CDE). We predicted 4,300 new CWP cases, assuming the dust concentrations remained at the levels of 2011. If advanced dustproof equipment was adopted, 537 fewer people would be diagnosed with CWP. In all, losses of 1.207 billion Renminbi (RMB, official currency of China) would be prevented and 4,698.8 healthy life years would be gained. Investments in advanced dustproof equipment would be total 843 million RMB, according to our study; the ratio of investment to restored economic losses was 1:1.43. Controlling workplace dust concentrations is critical to reduce the onset of pneumoconiosis and to achieve economic benefits. PMID:26098706

Coal Transition in the United States. An historical case study for the project 'Coal Transitions: Research and Dialogue on the Future of Coal'

Kok, Irem

2017-01-01

This is one of the 6 country case-studies commissioned to collect experience on past coal transitions. The 6 countries are: Czech Republic, the Netherlands, Poland, Spain, UK, USA. Their role in the Coal Transitions project was to provide background information for a Synthesis Report for decision makers, and provide general lessons for national project teams to take into account in developing their coal transitions pathways for the future. Over the past decade, the US started to cut down the production and the use of coal, which was affected by unfavorable market dynamics and changing federal regulatory environment. Even before the shale gas revolution and uptake of renewables diminish the use of coal in power generation, coal communities were struggling to meet ends. The regional cost differences between producing states, such as the Appalachian and the Powder River Basins, indicates that coal-impacted communities and workers have lived through the impacts of coal transition at varying magnitudes and time periods. In the period between 2014 and 2016, we have seen the crash of major US coal companies due to declining demand for US coal domestically and internationally. Furthermore, Obama administration's climate change policies negatively impacted coal-fired power plants with additional GHG emission requirements, contributing to declining domestic demand for coal. Combined with market downturn, US coal producers already struggle to pay for high operational costs and legal liabilities under bankruptcy conditions. With under-funded state budgets, coal states are also grappling with financial exposure resulting from pension, health care and reclamation liabilities of bankrupt coal companies. In 2016, former President Obama announced the Power Plus Plan to aid coal-impacted communities and workers to prepare for a low carbon future. The federal budget plan targeted diversification of local economies, funding of health and pension funds of miners and retraining for

An analysis of workers' morale in the coal mining industry using principal component analysis

1987-03-01

This paper looks at labour morale in the coal mining industry from 1967 to 1984. In particular it examines absenteeism, turnover and accidents over that period, as well as constructing an index of morale based on these variables. The data are taken from the North Nottinghamshire and South Yorkshire coal areas, and a comparison is made between these areas in the period leading up to the industrial action in 1984/85. The indices constructed indicate that morale, as measured by the first principal component, increased considerably during the years before the 1984 industrial dispute and that low morale was an unlikely reason for the dispute, although morale in South Yorkshire, a strike area, was lower than in North Nottinghamshire, largely a non-strike area. The steep rise in morale in both North Nottinghamshire and South Yorkshire follows closely the rise in unemployment nationally and may simply be an indication of conventional industrial relations assumptions that manifestations of negative worker attitudes are greatest when jobs are relatively plentiful, and considerably less so when jobs are scarce.

The number of international travellers is increasing worldwide. Although health risks related to international travel are important and generally well-understood, the perception of these risks was unclear among Turkish travellers. We aimed to evaluate the attitudes and health risk awareness of Turkish travellers travelling to African countries. A survey was performed of Turkish travellers bound for Africa from Istanbul International Ataturk Airport in July 2013. A total of 124 travellers were enrolled in the study. Among them, 62.9% had information about their destination but only 11.3% had looked for information on health problems related to travel and their destination. Of all travellers, 53.2% had at least one vaccination before travelling. The most commonly administered vaccine was for typhoid. Among the travellers, 69.3% and 80.6% had "no idea" about yellow fever vaccination and malaria prophylaxis, respectively. A positive correlation was found between a higher level of travellers' education and receiving the recommended vaccination for the destination. Our study revealed significant gaps in the vaccination and chemoprophylaxis uptake of Turkish travellers departing to Africa. An awareness and training program should be developed for travellers, as well as public health workers, to address health risks related to travel. Copyright © 2016 Elsevier Ltd. All rights reserved.

During an inspection by the Occupational Safety and Health Administration (OSHA) of a small coal slag processing plant with 12 current workers, four cases of pneumoconiosis were identified among former workers. The OSHA investigation consisted of industrial hygiene sampling, a review of medical records, and case interviews. Some personal sampling measurements exceeded the OSHA Permissible Exposure Limit (PEL) for total dust exposures of 15 mg/m(3), and the measured respirable silica exposure of 0.043 mg/m(3), although below OSHA's current PEL for respirable dust containing silica, was above the American Conference of Governmental Industrial Hygienists' Threshold Limit Value (TLV). Chest x-rays for all four workers identified small opacities consistent with pneumoconiosis. This is the first known report of lung disease in workers processing coal slag and raises concerns for workers exposed to coal slag dust. © 2015 Wiley Periodicals, Inc.

The United Mine Workers' Union claims that Australia is not getting enough for its coal. Moreover, coal company executives argue that the open market policy was failing the industry and that the export customers were manipulating Australian producers. Consequently, the unions are calling for Federal Government intervention and support the establishment of a national coal authority to co-ordinate the marketing of coal and investment in the industry. ills

Two Turkish coal (a bituminous and a brown coal) were extracted with NMP-CS2 (1:1 v/v) and NMP-EDA (1:17, v/v) at room conditions and with NMP and NMP/EDA under reflux. To obtain any effect of solvent swelling on extraction yield coals were also extracted at same conditions after swelling with NMP and EDA. The extraction yield was maximum in the NMP-CS2 mixed solvent for higher ranked coal, suggesting a synergistic effect of the system. It was possible to extract over 35 % of sub-bituminous coal by using NMP- CS2. The extraction of same coal with NMP under reflux gave an extraction yield of 33% suggesting the useful effect of solvent swelling and heat during the reflux period. A positive effect of pre-swelling with NMP and EDA on extraction yield and recovery of solid extracts were observed , especially for brown coal sample. Following the extraction, solid extracts were produced with less than 0.12 % in ash content for almost all extraction conditions.

Diffuse interlobular septal thickening (DIST) is an abnormality seen on high-resolution CT (HRCT) scanning of the thorax. While DIST may be present to variable extents in a number of lung conditions, it is uncommon as a predominant finding except in a few entities. This report features an ex-coal miner, thought to have coal workers' pneumoconiosis (CWP), in whom the HRCT scan showed no evidence of CWP and instead showed DIST. The patient's condition progressed incessantly towards death from severe secondary pulmonary hypertension. The case links fatal pulmonary hypertension to DIST, a pattern not previously described in coal workers.

In our research project entitled 'Chemical irritative and/or genotoxic effect of fumes of bitumen under high processing temperatures on the airways,' 73 mastic asphalt workers exposed to fumes of bitumen and 49 construction nonexposed workers were analyzed and compared with respect to polycyclic aromatic hydrocarbons (PAHs) exposure and exposure-related health effects. In order to assess the internal exposure the monohydroxylated metabolites of pyrene, 1-hydroxypyrene (1-OHP), and phenanthrene, 1-, 2- and 9-, and 3- and 4-hydroxyphenanthrene (OHPH) were determined in pre- and post-shift urinary samples. Significantly higher concentrations 1-OHP and OHPH were detected in the post-shift urine samples of 7 mastic asphalt workers working on the same construction site compared to the reference workers and all other 66 mastic asphalt workers. The adjusted mean OHPH in the reference, 66 mastic worker, and 7 worker subgroups was 1022, 1544, and 12919 ng/g creatinine (crn) respectively, indicating a marked rise in the 7 worker subgroup. In addition, there was a more than 12-fold increase of PAH metabolites from pre- to post-shift in these 7 workers, whereas in the other mastic asphalt workers there was only a twofold rise in PAH-metabolite concentration between pre- and post-shift values. The analysis of a drilling core from the construction site of the seven workers led to the detection of the source for this marked PAH exposure during the working shift as being coal tar plates, which were, without knowledge of the workers and coordinators, the underground material of the mastic asphalt layer. The evaluation of the stationary workplace concentration showed enhanced levels of phenanthrene, pyrene, fluorene, anthracene, and acenaphthene during working shifts at the construction site of these seven workers. Our study shows that biological monitoring is also a useful tool for the detection of unrecognized sources with high PAH concentrations.

A retrospective mortality study of workers exposed to radon in a Brazilian coal mine

High levels of radon concentration were found in the underground workplace of an underground coal mine in Parana state, which has been in activity since 1942. Many of these workers were exposed for a long period of time to a work atmosphere with high radon, and radon decay products concentration. Taking this into account, it was decided to carry on a historical cohort, study with the workers' of this mining universe (underground and surface) in. order to evaluate the possible health effects related to this exposure, by means of a retrospective study of mortality. Through multiple strategies, it was possible to trace the vital status of 90% of the cohort. The causes of the deaths were identified by active search, of Death Declarations in the Health Office of Parana state and also in and other states. The success rate of cause of death identification was 100%. The final, cohort included 1946 underground workers and 910 surface workers. Standard mortality ratio (SMR) analysis showed lower mortality from all causes for both underground (SMR-88, 95%CI=78-98) and surface workers (SMR=96, 95%CI=81- 113). A highly significant SMR was observed for pneumonia cause of death among surface ((SMR=284, 95%CI=118-684) and underground miners (SMR-254, 95%CI=140-459), while a highly significant lung cancer mortality risk was observed only for underground miners (SMR=177, 95%CI=105-299) with a significant trend in relation to years of underground work (duration of exposure). Taking into account that mortality from smoking-related cancers other than lung cancer is not elevated in underground workers and diesel equipment were not used at this mine, the results suggest that the exposure to radon daughters may have been responsible for the lung cancer excess among underground workers. This work consists of the first historical Brazilian cohort involving miners exposed to radon and one of the few historical cohorts built in Brazil. It should be considered the fact that many workers of

2013-01-01

We studied mainstream couples in The Netherlands and Turkey as well as Turkish-Dutch immigrant couples to address cultural factors associated with marital satisfaction. A total of 13 Turkish (mainstream couples living in Turkey), 19 Turkish-Dutch (Turkish immigrant couples living in The Netherlands), and 17 Dutch (mainstream couples living in The Netherlands) married dyads (total of 98 individuals) were independently interviewed about positive and negative characteristics of marriages, determinants of general marital satisfaction and dissatisfaction, spousal communication, marital conflict, and marital roles. Multivariate tests revealed ethnic group differences on all marriage-related domains except the conflict resolution strategies. However, univariate analyses showed differences in few themes within domains; main differences were assessed between the Turkish/Turkish-Dutch (who put more emphasis on children and economical aspects) and Dutch couples (who put more emphasis on behavior, and personality of the spouse, reciprocity, emotional sharing, and psychological roles). Turkish-Dutch couples were more similar to Turkish than to Dutch couples. Results were discussed in light of the socioeconomic development and cultural value theories, which are believed to provide a useful framework for understanding the role of culture in marital satisfaction.

To explore the difference of cumulative incidence rate of coal workers' pneumoconiosis (CWP) among four large state-owned coal enterprises in northern China, we created an index system for evaluating the quality of comprehensive measures against CWP and applied the system to evaluate and compare the measures of the four coal enterprises. A two-round Delphi investigation was conducted to identify the indicators in the index system. The weight values of the indicators were calculated with analytic hierarchy process methods. Measures of CWP, mine annals, records and other information in each coal mine of the four enterprises were collected. The evaluation scores, which ranged from 0 to 100, were calculated and compared with. A three-grade index system with 3 first-grade indicators, 9 second-grade indicators and 44 tertiary-grade indicators was established. The expert authority coefficient ( C r ) was 0.75 and the Kendall's coefficient of concordance (Kendall's W ) was 0.15 (χ 2 =193.30, Psystem could be effectively used for evaluation and comparison of the comprehensive measures against CWP among different enterprises. The geological conditions and dust control engineering technology played an important role in preventing and controlling CWP. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2017-01-01

This is one of the 6 country case-studies commissioned to collect experience on past coal transitions. The 6 countries are: Czech Republic, the Netherlands, Poland, Spain, UK, USA. Their role in the Coal Transitions project was to provide background information for a Synthesis Report for decision makers, and provide general lessons for national project teams to take into account in developing their coal transitions pathways for the future. Spain has had a long tradition of coal mining at least since the 18. century. However, it is also one of the jurisdictions committing to phase-out of subsidies and implementing it in recent times. This case study discusses the main features of the coal transition in Spain, the factors influencing this transition as well as the policies which both drove it and accompanied their detrimental socioeconomic effects on the workers and regions. The analysis is based on a desktop research of relevant documents, including official communications from the Ministry of Industry (MINETUR) and the European Commission as well as statements of position from the industry association (CARBUNION) and labour unions (UGT and CCOO). Documents on national coal from other institutions (Foundations, NGOs) have also been consulted. Finally, an analysis of articles in the mass media has been carried out. This contains useful statements from different types of stakeholders. A strong reduction in production and employment in the coal industry has been experienced at least in the last two decades in this country. Successive plans by the government have aimed at reducing coal production, early retirement of workers and closing mines. Caught in the middle of the mining coalition on the one hand and EU legislation and public opinion on the other, the government has had to approve drastic measures leading to phase out. On the other hand, it has tried to accompany the phase out with measures which have tried to mitigate the negative impact on the affected zones

It has recently been suggested that the inhalation of coal in the absence of complicated coal workers' pneumoconiosis (CWP) or smoking can lead to disabling airways obstruction. The cause of such obstruction has been variously attributed to emphysema or bronchitis. The frequency of significant airways obstruction in a group of United States coal miners seeking compensation for occupationally induced pulmonary impairment was therefore determined.

Based on the rigorous situation of safety production in coal mines, the paper analyzed the statistical data of recent accidents indexes in Henan's coal mines. Using investigation and comparison analysis methods, a specified analysis on mining conditions, technical facility level, safety input and vocational quality of workers in Henan's coal mines was conducted. The result indicates that there have been existing such main safety production problems as weak safety management, low-level facilities, inadequate safety input and poor vocational quality and so on. Finally it proposes such reference solutions as to establish and perfect coal mining supervision and management system, to increase safety investment into techniques and facilities and to strengthen workers' safety education and introduction of more high-level professional talents.

Full Text Available The aim of this article is to investigate the impact of new Turkish commercial code and Turkish accounting standards on accounting education. This study takes advantage of the survey method for gathering information and running the research analysis. For this purpose, questionnaire forms are distributed to university students personally and via the internet.This paper includes significant research questions such as “Are accounting academicians informed and knowledgeable on new Turkish commercial code and Turkish accounting standards?”, “Do accounting academicians integrate new Turkish commercial code and Turkish accounting standards to their lectures?”, “How does modern accounting education methodology and technology coincides with the teaching of new Turkish commercial code and Turkish accounting standards?”, “Do universities offer mandatory and elective courses which cover the new Turkish commercial code and Turkish accounting standards?” and “If such courses are offered, what are their names, percentage in the curriculum and degree of coverage?”Research contributes to the literature in several ways. Firstly, new Turkish commercial code and Turkish accounting standards are current significant topics for the accounting profession. Furthermore, the accounting education provides a basis for the implementations in public and private sector. Besides, one of the intentions of new Turkish commercial code and Turkish accounting standards is to foster transparency. That is definitely a critical concept also in terms of mergers, acquisitions and investments. Stakeholders of today’s business world such as investors, shareholders, entrepreneurs, auditors and government are in need of more standardized global accounting principles Thus, revision and redesigning of accounting educations plays an important role. Emphasized points also clearly prove the necessity and functionality of this research.

In the 1950s the Pneumoconiosis Field Research (PFR) programme was set up to study the health of British coal workers. Studies included regular health surveys, an intensive characterisation of workers' individual exposures, and entry to a cohort followed up to the present for cause-specific mortality. This study reports on analyses of cause-specific mortality in a cohort of almost 18 000 men from 10 British collieries. External analyses used standardised mortality ratios (SMRs), comparing observed mortality with reference rates from the regions in which the collieries were situated. Causes investigated include lung and stomach cancers, chronic obstructive pulmonary disease and cardiovascular endpoints. Internal analyses used Cox regression models with time-dependent exposures adjusting for the confounding effects of age, smoking, cohort entry date and regional differences in population mortality rates. Several causes showed evidence of a healthy worker effect early in the follow-up, with a deficit in the SMR diminishing over time. For most of the causes there was a significant excess in the latter part of follow-up. Internal analyses found evidence of an association between increased risks of lung cancer and increased quartz exposure, particularly at a lag of 15 years. Risks of mortality from non-malignant respiratory disease showed increases with increased exposure to respirable dust. This paper adds to the evidence on the long-term effects of exposure to coalmine dust on mortality from respiratory diseases.

Highlights in the history of efforts to prevent occupational lung disease among coal miners in the United States are reviewed. The Federal Coal Mine Health and Safety Act of 1969 is summarized, and the sources and effects of its provisions to prevent coal workers' pneumoconiosis are examined. Descriptions follow of the identification of coal workers' pneumoconiosis as a disease, identification of respirable coal mine dust as its cause, and establishment and enforcement of an exposure limit. The development of prevention efforts focusing on surveillance of both exposure and outcome and of enforcement of dust control methods is examined.

Emphysema and chronic obstructive pulmonary disease in coal miners

Energy Technology Data Exchange (ETDEWEB)

Tomas, L.H.S. [Medical College of Wisconsin, Milwaukee, WI (United States)

2011-03-15

Coal mining remains a major industry that has workers at risk for developing chronic lung disease. Aside from simple coal workers' pneumoconiosis and progressive massive fibrosis, the development of emphysema and obstructive lung disease independent of smoking may be underappreciated. This article reviews more recent studies that may help rectify this faulty view. Cumulative exposure to coal dust is a significant risk factor for the development of emphysema and has an additive effect to smoking. Increased coal dust exposure is associated with increased risk of death from chronic obstructive pulmonary disease (COPD). In newly employed coal miners, bronchitic symptoms are associated with a rapid decline in lung function within 2 years after starting work. In evaluating impairment, the chest radiograph may be helpful as a marker of exposure but the diffusing capacity is most correlated with dyspnea, whereas the emphysema computed tomography score has good association with expiratory flow limitation. Latest studies further support the association of emphysema and COPD with coal dust exposure. Increased cumulative exposure may also increase risk of death from these diseases.

Gallium-67 citrate imaging in underground coal miners

Kanner, R.E.; Barkman, H.W. Jr.; Rom, W.N.; Taylor, A.T. Jr.

1985-01-01

Twenty-two underground coal workers with 27 or more years of coal dust exposure were studied with gallium-67 citrate (Ga-67) imaging. Radiographic evidence of coal workers indicates that pneumoconiosis (CWP) was present in 12 subjects. The Ga-67 scan was abnormal in 11 of 12 with, and 9 of 10 without, CWP. The Ga-67 uptake index was significantly correlated with total dust exposure (p less than 0.01) and approached significant correlation with the radiographic profusion of the nodules (0.10 greater than p greater than 0.05). There was no correlation between Ga-67 uptake and spirometric function, which was normal in this group of patients; furthermore, increased lung uptake of gallium did not indicate a poor prognosis in subjects no longer exposed to coal dust. While coal dust exposure may be associated with positive Ga-67 lung scan in coal miners with many years of coal dust exposure, the scan provided no information not already available from a careful exposure history and a chest radiograph. Since Ga-67 scanning is a relatively expensive procedure the authors would recommend that its use in subjects with asymptomatic CWP be limited to an investigative role and not be made part of a routine evaluation

As in any other institution, the success of hospitals, which use approximately one-half of all resources in the health sector, depends on moving human resources toward the institution's goals. Ensuring that the workers are used intentionally for specific, predetermined goals, and that the workers are motivated toward achieving these institutional goals are the responsibilities of the managers. In this study, the leadership attitudes of the higher rank executive officers in Turkish Armed Forces' military hospitals were evaluated. The managerial grid developed by Blake and Mouton was used to evaluate the leadership attitudes of the officers. A total of 172 questionnaires was sent out to managers, but only 142 (82.6%) were returned completed. The study results show that the managers substantially preferred team leadership styles in terms of leadership philosophy, planning, and evaluation functions, but preferred task-oriented leadership and mid-way leadership styles in terms of execution. Also, it was found that 72% of all managers practiced team leadership in terms of the overall leadership manner. It seems as if the type of leadership participants preferred was team leadership, and the least was passive leadership. From this finding, we suggest that the managers in Turkish Armed Forces' hospitals are not only interested in their work and goals, but also in the interests of their workers as human beings.

Coal dust darkens the bargaining table

Raskin, A.H.

1978-04-24

Reverberations from the lengthy winter 1978 coal strike are sure to have effects on other unions--teamsters, postal workers, trainmen, steel workers--the author says. This debacle in the coal fields obliges Americans to recognize that, bad as union dictatorship undoubtedly is, union anarchy is potentially more destructive. Miners showed that anarchy pays; they demonstrated that the rank-and-file with control over a vital source can get a better deal by spurning the settlements made by their elected leaders and defying court back-to-work orders. President Carter's encouragement of defiance is discussed. The U.M.W. precedent may encourage all rebel groups in unions to demand a seat at the bargaining table. (MCW)

Objective: To study the CT appearance of the hilar and mediastinal enlarged lymph nodes in coal worker's pneumoconiosis (CWP), its pathological basis and diagnostic value for CWR complicated with lung cancer. Methods: (1) Twelve isolated lungs with CWP obtained at autopsy were inflated and fixed. CT scan was performed. The pathologic findings of enlarged lymph nodes were identified. (2) CT findings of hilar and mediastinal enlarged lymph nodes of 71 cases with CWP and 22 cases of CWP complicated with lung cancer were analyzed. Results: (1) Most of the enlarged hilar and mediastinal lymph nodes in simple CWR was in third stage of fibrosis. The fourth stage of fibrosis was only seen in lymph nodes of a case with complicated CWP. In this case the necrotic materials of lymph nodes eroded adjacent bronchi and vessels, and coalesced with progressive massive fibrosis (PMF). (2) The average number of lymph nodes in cases of complicated CWP was more than that of simple CWP (P 2 cm was 7.4%. (3) The prevalence of lymph nodes calcification in CWP was 61.1%, but egg shell calcification was only 14.7%. (4) In the cases of CWP complicated with lung cancer, lymph node > 2 cm was 20.8%, that was more than CWP (P 3 cm was 7.6%. Conclusion: Lymph nodes up to 1 cm may have dust fibrosis and coal silicosis nodules. The lymph nodes >2 cm is more common in CWP complicated with lung cancer than in simple CWP. The lymph nodes > 3 cm indicates higher probability of CWP with lung cancer than PMF

With the increasing concerns about the environment, energy producers and governments are looking at developing clean energy sources. However, Turkey has limited clean energy resources and is using low grade coal which has high sulphur content as an alternative energy source. The aim of this paper is to study the possibility of generating clean fuel from Edirne Lignite and to get a better understanding of chemical mechanisms involved in coal leaching with hydrofluoric acid (HF) solutions. Leaching was conducted on Edirne Lignite with HF solution at ambient temperature and the effects of parameters such as reaction time and concentration of acid solutions on the process were evaluated. The optimum conditions were found and it was shown that ash levels can be reduced from 28.9% to 10.5% and the calorific value increased by 500kcal/kg with the HF leaching method. This study demonstrated that the production of clean fuel from high sulphur lignite is possible.

2017-03-01

To change unsafe behavior through adjusting people’s safety attitudes has become an important measure to prevent accidents. Demographic variables, as influential factors of safety attitude, are fundamental and essential for the research. This research does a questionnaire survey among coal mine industry workers, and makes variance analysis and correlation analysis of the results in light of age, length of working years, educational level and experiences of accidents. The results show that the coal miners’ age, length of working years and accident experiences correlate lowly with safety attitudes, and those older coal miners with longer working years have better safety attitude, as coal miners without experiences of accident do.However, educational level has nothing to do with the safety attitude. Therefore, during the process of safety management, coal miners with different demographic characteristics should be put more attention to.

Full Text Available The functions of the scientific texts under the informative text type are referring to the results of a research, reinterpreting certain research results, or reaching original results. When literature reviewed, it is observed that although the studies for creating scientific text have increased recently, it seems that the desired outcome is not achieved. In addition to teaching Turkish as a mother tongue, teaching it as a foreign language has also started to gain importance. For this reason, it is necessary to carry out such studies in order to increase the productivity in the field of teaching Turkish to foreigners. The aim of the study is to determine the orientations related to the rhetorical arrangement of the scientific texts on teaching of Turkish as a foreign language, which are included in the textbooks of the International Training and Education of Turkish Language Congresses as a full text and to evaluate these texts in terms of their specific functions. Findings and determinations revealed in the study are based on a corpus comprised of a total of 64 texts included in proceedings books, written in Turkish and related to teaching Turkish to foreigners. The study is structured by qualitative research method. The data were obtained by qualitative data collection techniques through document scanning and were examined within the framework of the scientific text criteria specified by Huber and Uzun (2001. Two out of 64 articles in the sample of the study revealed that none of the expected functional steps in the introduction, main and final sections were found. No work has been found that covers all of the functional steps in the introduction, main and final sections.

Full Text Available The coal mine excavation, transportation and coal cutting process are involved in hazards and risks that can result in fatalities, injuries and diseases, if these are not properly managed. This study has been undertaken for assessment of the safety and health issues amongst the mines workers. Convenience sampling technique was exercised upon 97 mine workers and interviewed with the help of set questionnaire. Personnel protection to workplace environment was monitored by using physical observation and scientific analysis. All parameters were measured against national and international protocols pertaining to labor law at coal mines. It has been determined that very high risk was persisting while mine excavation, coal cutting and transportation processes. Previous record of last five years was suggesting that 04 deaths happened due to roof fall, 03 fatalities occurred through suffocation by inhaling toxic gases, one causality happened via rope haulage pulley, and also one death due to stone fall down from mine shaft. 121 workers injured in different kinds of accidents within five years. It has been learnt from in-depth analysis that maximum of health risk and subsequent health damages are triggering due to lack of awareness, non-compliance of labor as well as mines laws. Thus, it is recommended that government should not allow coal mining contractors and companies, those which are failing in compliance with the suggested standards.

Introduction: Senior managers' attitudes towards safety are very important regarding the safety practices in an organization. The study is to describe the current situation of senior managers' attitudes towards safety in the Chinese coal industry. Method : We evaluated the changing trends as well as the reasons for these changes in the Chinese coal industry in 2009 and in 2014 with 168 senior manager samples from large Chinese state-owned coal enterprises. Evaluations of 15 safety concepts were performed by means of a questionnaire. Results and Conclusions : Results indicate that, in 2014, three concepts were at a very high level (mean > 4.5), and six were at a relatively high level (4.5 > mean > 4.0). Analyses of changing trends revealed that nine concepts improved significantly, while four greatly declined in 2014 compared to those in 2009. The data reported here suggest that the reasons for the significant improvement with respect to the nine concepts include the improvement in social and legal environments, the improvement of the culture of social safety, workers' safety demands being met, and scientific and technical advances in the coal industry. The decline of the four concepts seemed to be caused by a poor awareness of managers in the coal industry that safety creates economic benefits, insufficient information on safety, inadequate attention to the development of a safety culture and safety management methods, and safety organizations and workers' unions not playing their role effectively. Practical Applications : We therefore recommend strengthening the evidence that safety creates economic benefits, providing incentives for employees to encourage their participation in safety management, and paying more attention to the prevention of accidents in coal mines via safety organizations and unions. These results can provide guidelines for workers, industrialists, and government regarding occupational safety in the whole coal industry.

The paper outlines the status of Australian coal mining industry with respect to safety and welfare of the mine employee. The impact of the longer shift hours and compressed working week are discussed in relation to workers safety and employment levels. Longer shift hours and compressed works have been shown to be a benefit to miners, both in safety and socially. The paper also examines the role of each of government organisations, the mining and manufacturing industries on the issue and goes on to describe the various environmental control measures introduced to the Australian coal mines to ensure that high safety standards are maintained. Dust monitoring and control, noise pollution control, and diesel particulate control measures have been targeted vigorously and as a result there has been a continued drop in the coal mine related diseases as well as a decline in the workers lost time injury claims. 11 refs., 7 figs., 6 tabs.

A study of trends in occupational risks associated with coal mining

Energy Technology Data Exchange (ETDEWEB)

Amoundru, C.

1980-10-01

The occupational risks associated with underground coal mining can be categorized as either industrial accidents or occupational diseases. Since 1957, the number of fatal accidents per million tons of coal produced has dropped by a factor of four. The number of industrial accidents in general decreased by 30% during 1967-75. The main occupational diseases affecting miners are arthrosis, deafness, and pneumoconiosis. To make an objective comparison with the health hazards from other sources of energy, the probable risks facing workers in a modern mine should be compared with those currently confronting workers in other industries.

Energy and exergy efficiencies in Turkish transportation sector, 1988-2004

International Nuclear Information System (INIS)

Ediger, Volkan S.; Camdali, Unal

2007-01-01

This study aims at examining energy and exergy efficiencies in Turkish transportation sector. Unlike the previous studies, historical data is used to investigate the development of efficiencies of 17 years period from 1988 to 2004. The energy consumption values in tons-of-oil equivalent for eight transport modes of four transportation subsectors of the Turkish transportation sector, including hard coal, lignite, oil, and electricity for railways, oil for seaways and airways, and oil and natural gas for highways, are used. The weighted mean energy and exergy efficiencies are calculated for each mode of transport by multiplying weighting factors with efficiency values of that mode. They are then summed up to calculate the weighted mean overall efficiencies for a particular year. Although the energy and exergy efficiencies in Turkish transport sector are slightly improved from 1988 to 2004, the historical pattern is cyclic. The energy efficieny is found to range from 22.16% (2002) to 22.62% (1998 and 2004) with a mean of 22.42±0.14% and exergy efficiency to range from 22.39% (2002) to 22.85% (1998 and 2004) with a mean of 22.65±0.15%. Overall energy and exergy efficiencies of the transport sector consist mostly of energy and exergy efficiencies of the highways subsector in percentages varying from 81.5% in 2004 to 91.7% in 2002. The rest of them are consisted of other subsectors such as railways, seaways, and airways. The overall efficiency patterns are basically controlled by the fuel consumption in airways in spite of this subsector's consisting only a small fraction of total. The major reasons for this are that airways efficiencies and the rate of change in fuel consumption in airways are greater than those of the others. This study shows that airway transportation should be increased to improve the energy and exergy efficiencies of the Turkish transport sectors. However, it should also be noted that no innovations and other advances in transport technologies are

Capitalist collective action: competition, cooperation and conflict in the coal industry

Energy Technology Data Exchange (ETDEWEB)

John R. Bowman [City University of New York, New York, NY (USA). Queens College

2006-11-15

This volume presents a theory of capitalist collective action and a case study of the pre-World War II American coal industry to which the theory is applied. The author examines the irony of capitalist firms that do not want to compete with each other, but often cannot avoid doing so. He then explains under what conditions businesses would be able to organize their competition and identifies the economic and political factors that facilitate or inhibit this organization. The case study not only illustrates the theory, but demonstrates how the competitive relations of capitalist firms are critically important determinants of their political behavior. The author argues that the traditional Marxist concern with conflict between workers and capitalists should be supplemented with a concern for the competitive conflicts among capitalists.

Obstructive sleep apnea syndrome obstructive sleep apnea syndrome is associated with symptoms including habitual snoring, witness apnea and excessive daytime sleepiness. Also obstructive sleep apnea syndrome is related to some occupations which are needed attention for work accident. We aimed to determine the prevalence of snoring, witnessed apnea and excessive daytime sleepiness in coal workers and healthy adults in Zonguldak city center, and also evaluate the differences between these groups. This study consisted of 423 underground coal workers and 355 individuals living in centre of Zonguldak. Study and comparison group were chosen by nonstratified randomized sampling method. Data were collected by a questionnaire that included information regarding snoring, witnessed apnea and excessive daytime sleepiness. Mean age was 43.3 ± 6.05 years in miners and 44.3 ± 11.8 years in comparison group. In miners, snoring frequency was determined as 42.6%, witnessed apneas were 4.0%, and daytime sleepiness were 4.7%. In comparison group, these symptoms were 38.6%, 4.8% and 2.8% respectively. There were no statistical differences between coal workers and comparison group in these symptoms. Also snoring prevalence was higher in smoker miners. We found that major symptoms of obstructive sleep apnea syndrome in coal workers are similar to general population in Zonguldak. Further studies that constucted higher populations and with polysomnography are needed to evaluate these findings.

This study is centred on the analysis and evaluation of risk noise to which the workers are exposed in coal mines in ASTURIAS. To this end, great many measurements were carried out on the amount in workers belonging to the various mining professional categories. The results of the study show that there are a great many workers exposed to level of noise which notably surpass those limits established by the Royal Decree, 1316/1989 on the protection of worker against risks from exposure to noise at work particularly those involved in picking and in the preparation, which are, in fact, the most typical post in underground coal mining.

As part of the Study carried out to determine the radiological impact of the four main Spanish coal-fired power plants, the Study on the As Pontes Coal-Fired Coal Power Plant was finalized. In the Report containing the study are included every measurement performed, as well as the modelling and evaluations carried out in order to assess the radiological impact. The general conclusion obtained is that under a radiological point of view, the impact of this installation on the public and the environment is very small. Also the radiological impact on the workers of the installation was assessed, obtaining too very small increases over the natural background. (Author) 61 refs.

ANFO, an effective and inexpensive explosive, is widely used in rock blasting operations. However, for weak strata, ANFO often produces too much shock energy and leads to inefficiencies in the mining operation. Especially in Turkish surface coal mines where ANFO is used with the decking system, it is desirable to develop a low shock energy but a high heave energy ammonium nitrate based explosive. 3 refs., 9 figs., 1 tab.

2004-01-01

The main source of radiation exposure in most underground mining operations is radon and radon decay products. The situation of radon exposure in underground mining in Brazil is still unknown, since there has been no national regulation regarding this exposure. A preliminary radiological survey in non-uranium mines in Brazil indicated that an underground coal mine in the south of Brazil had high radon concentration and needed to be better evaluated. This paper intends to present an assessment of radon and radon decay product exposure in the underground environment of this coal mining industry and to estimate the annual exposure to the workers. As a product of this assessment, it was found that average radon concentrations at all sampling campaign and excavation sites were above the action level range for workplaces of 500-1500 Bq m -3 recommended by the International Commission on Radiological Protection-ICRP 65. The average effective dose estimated for the workers was almost 30 times higher than the world average dose for coal miners

Full Text Available The aim of this study is to identify the traditional Turkish motifs and its relations among present industrial designs. Traditional Turkish motifs played a very important role in 16th century onwards. The arts of the Ottoman Empire were used because of their symbolic meanings and unique styles. When we examine these motifs we encounter; Tiger Stripe, Three Spot (Çintemani, Rumi, Hatayi, Penç, Cloud, Crescent, Star, Crown, Hyacinth, Tulip and Carnation motifs. Nowadays, Turkish designers have begun to use these traditional Turkish motifs in their designs so as to create differences and awareness in the world design. The examples of these industrial designs, using the Turkish motifs, have survived and have Ottoman heritage and historical value. In this study, the Turkish motifs will be examined along with their focus on contemporary Turkish industrial designs used today.

The determination of methane resources from liquidated coal mines

Science.gov (United States)

Trenczek, Stanisław

2017-11-01

The article refers to methane presented in hard coal seams, which may pose a serious risk to workers, as evidenced by examples of incidents, and may also be a high energy source. That second issue concerns the possibility of obtaining methane from liquidated coal mines. There is discussed the current methodology for determination of methane resources from hard coal deposits. Methods of assessing methane emissions from hard coal deposits are given, including the degree of rock mass fracture, which is affected and not affected by mining. Additional criteria for methane recovery from the methane deposit are discussed by one example (of many types) of methane power generation equipment in the context of the estimation of potential viable resources. Finally, the concept of “methane resource exploitation from coal mine” refers to the potential for exploitation of the resource and the acquisition of methane for business purposes.

This study aims to to evaluate the possible health effects on workers in a underground coal mining that were exposed to radon and its decay products without the knowledge of the exposure risk. We established a historical cohort of workers in this mining which included 2856 workers, 1946 underground workers and 910 surface workers, and was carried out a retrospective tracking of mortality in this cohort between 1979 and 2002. Through multiple strategies for monitoring, involving several national institutions, was possible to trace the vital status of 92% of the cohort and 100% of the causes of deaths. The results showed that employees of underground coal mining in Parana had a risk of mortality from lung cancer higher than might be expected to the male population of the state of Parana, observing an increase in risk with the time of underground service. However, this increase in mortality from lung cancer was not observed for surface workers. Among several carcinogenic agents present in the mine environment, radon gas and its decay products can be identified as the major cause for this increase in risk of lung cancer for these workers, once other epidemiological studies in coal mining, which have no risk of exposure to radon, do not present an increased of mortality risk from lung cancer

Inter-individual variation in the severity of pneumoconiosis has been described, even with the same environmental exposure. We hypothesized that TNF-alpha promoter polymorphisms associate with lung responses to environmental exposure in coal worker's pneumoconiosis (CWP) patients. We examined polymorphisms at -238, -308, and -376 in 124 patients with CWP who had similar dust exposure history and in 122 non-exposed controls. CWP patients were divided into two groups: (1) nodular CWP (n = 84): (2) progressive massive fibrosis (PMF) (n = 44). The -308 A allele frequency was higher in patients with CWP compared to controls (6.35% and 2.05%, P {lt} 0.01). It was also higher in patients with nodular CWP compared to PMF (P {lt} 0.05). Logistic regression analysis revealed that patients with the -308 A allele were 3.8 times (P = 0.036) and those with smoking habit were 2.3 times (P {lt} 0.002) more likely to have nodular CWP than PMF. Thus TNF-alpha-308 A allele might interact with smoking to enhance susceptibility to nodular CWP.

Are Turkish University Students Autonomous or Not?

Full Text Available The present study tried to determine Turkish learners’ attitudes, and the Turkish education system’s approach towards learner autonomy with regard to three main points: 1 whether Turkish university students are aware of learner autonomy or not 2 whether Turkish university students have the characteristics of autonomous learners (whether they are autonomous learners or not, and 3 if the Turkish education system is suitable for fostering learner autonomy or not from the viewpoint of the participants. Participants were 50 second grade learners in the English Language Teaching Departments of Hacettepe University (N=10, Mehmet Akif Ersoy University (N=10, and Uludag University (N=30 who had already taken courses about learner autonomy.  The data were collected by means of a questionnaire which had two Likert-scale sections and an open-ended questions section. The first Likert-scale section contained 15 characteristics of autonomous learners each of which was rated by the participants in a scale from strongly disagree to agree, from 1 to 5. In the second Likert-scale section, the participants were asked to rate the Turkish education system’s five basic elements such as school curriculums, course materials, approaches used by the teachers in classrooms, learning activities, and classroom settings. Additionally, learners’ opinions about their awareness and understanding of learner autonomy were gathered by five open ended questions. The results proposed that the participants were aware of learner autonomy, and had the characteristics of autonomous learners. On the other hand, results showed that the Turkish education system was not suitable for autonomous learners and did not foster learner autonomy. The findings suggested that the Turkish education system should be designed again in such a way to support the autonomous learners and to foster learner autonomy in all sections of the education.

PHONETIC AND NON-PHONETIC LANGUAGES: A CONTRASTIVE STUDY OF ENGLISH AND TURKISH PHONOLOGY FOCUSING ON THE ORTHOGRAPHY-INDUCED PRONUNCIATION PROBLEMS OF TURKISH LEARNERS OF ENGLISH AS A FOREIGN LANGUAGE (TURKISH EFL LEARNERS

Full Text Available The present study aims to investigate the pronunciation problems of Turkish learners of English as a foreign language (Turkish EFL learners due to the orthography system of English. Orthography is a standardized system for using a particular writing system (script to write a particular language. It includes rules of spelling, and may also concern other elements of the written language such as punctuation and capitalization. It is clear that English is a non-phonetic and Turkish is a phonetic language, so it is very natural for the Turkish EFL learners to have some phonological problems in learning English. The author has done a contrastive study concerning three linguistic systems, i.e. consonants, vowels and syllable structures of English and Turkish to find the causes of the problems to be used in teaching English as a foreign language to Turks. The results of the study showed that the problems under discussion are caused by some differences between the orthography and the phonology of the two languages. As a result, English teachers, to be helpful, should focus on the differences and help the Turkish learners overcome the pronunciation problems. The author of the paper believes that an English teacher should be both aware of the differences and be able to teach them effectively to the Turkish EFL learners.

NEGATIVE CURRENCY-RISK-EXPOSURE FOR TURKISH EQUITIES

Directory of Open Access Journals (Sweden)

Salvatore J. Terregrossa

2016-04-01

Full Text Available Currency-risk-exposure is an issue for Turkish equities, from two different angles: internationaltrade and foreign-portfolio-investment. The likely effect is positive for the former, and negative for the latter aspect. Consequently, the overall or net effect on equity value depends on which of these aspects of currency-risk-exposure has the greater impact. The present empirical analysis estimates currency risk of Turkish equities within a multi-factor regression setting, utilizing the framework of the Security Market Plane (SMP model. The SMP model embodies a conditional relation among three variables: beta, realized excess market-return, and expected excess portfolio-return. The SMP empirical framework is extended to include a currency-risk-factor in the present analysis. The currency-risk-factor is specified as the excess return to holding foreign currency (€; $, relative to holding domestic currency (Turkish Lira. The SMP-related factor is the cross-product term of beta and realized excess market-return (β it rMt . A regression of realized excess portfolio-returns against the corresponding currency-risk-factor and cross product-term (β it rMt finds that the Turkish stocks represented in the analysis generally have overall negative currency-risk-exposure; suggesting that unexpected currency depreciation generally leads to lower values for Turkish stocks (and portfolios of Turkish stocks. Thus, after accounting for the SMP-related interaction-effect between beta and realized excess marketreturn, currency risk is found to command a premium for the Turkish stocks represented in the analysis.

The achievement of author in this matter makes him well known in the country where he lives. However, the topic choice is as important as an artist’s language skills. That’s why poets and authors prefer universal subjects such as love, death, religion, religious personalities (like prophets, saints, etc. and humanity (man's way of living and right to live in their works. If artists produce universal subjects with a clear language, a fluent wording and a strong story line, this achievement makes them famous both nationally and internationally.

2014-01-01

Silicosis and coal worker's pneumoconiosis are serious occupational respiratory diseases associated with the coal mining industry and the inhalation of respirable dusts containing crystalline silica. The purpose of this study (funded by the Mine Health and Safety Council of South Africa) was to evaluate the individual contributions of underground coal mining tasks to the respirable dust and respirable silica dust concentrations in an underground section by sampling the respirable dust concentrations at the intake and return of each task. The identified tasks were continuous miner (CM) cutting, construction, transfer of coal, tipping, and roof bolting. The respirable dust-generating hierarchy of the tasks from highest to lowest was: transfer of coal > CM right cutting > CM left cutting > CM face cutting > construction > roof bolting > tipping; and for respirable silica dust: CM left cutting > construction > transfer of coal > CM right cutting. Personal exposure levels were determined by sampling the exposures of workers performing tasks in the section. Respirable dust concentrations and low concentrations of respirable silica dust were found at the intake air side of the section, indicating that air entering the section is already contaminated. The hierarchy for personal respirable dust exposures was as follows, from highest to lowest: CM operator > cable handler > miner > roof bolt operator > shuttle car operator, and for respirable silica dust: shuttle car operator > CM operator > cable handler > roof bolt operator > miner. Dust control methods to lower exposures should include revision of the position of workers with regard to the task performed, positioning of the tasks with regard to the CM cutting, and proper use of the line curtains to direct ventilation appropriately. The correct use of respiratory protection should also be encouraged.

Coals and coal ashes, raw materials and by-products, in coal-fired power plants contain naturally occurring radioactive materials (NORM). They may give rise to internal exposure to workers due to inhalation of airborne particulates containing radioactive materials. It is necessary to characterize radioactivity concentrations of the materials for assessment of radiation dose to the workers. The objective of the present study was to analyze radioactivity concentrations of coals and by-products at four coal-fired plants in Korea. High purity germanium detector was employed for analysis of uranium series, thorium series, and potassium 40 in the materials. Radioactivity concentrations of {sup 226}Ra, {sup 228}Ra, and {sup 40}K were 2⁓53 Bq kg{sup -1}, 3⁓64 Bq kg{sup -1}, and 14⁓431 Bq kg{sup -1} respectively in coal samples. For coal ashes, the radioactivity concentrations were 77⁓133 Bq kg{sup -1}, 77⁓105 Bq kg{sup -1}, and 252⁓372 Bq kg{sup -1} in fly ash samples and 54⁓91 Bq kg{sup -1}, 46⁓83 Bq kg{sup -1}, and 205⁓462 Bq kg{sup -1} in bottom ash samples. For flue gas desulfurization (FGD) gypsum, the radioactivity concentrations were 3⁓5 Bq kg{sup -1}, 2⁓3 Bq kg{sup -1}, and 22⁓47 Bq kg{sup -1}. Radioactivity was enhanced in coal ash compared with coal due to combustion of organic matters in the coal. Radioactivity enhancement factors for {sup 226}Ra, {sup 228}Ra, and {sup 40}K were 2.1⁓11.3, 2.0⁓13.1, and 1.4⁓7.4 for fly ash and 2.0⁓9.2, 2.0⁓10.0, 1.9⁓7.7 for bottom ash. The database established in this study can be used as basic data for internal dose assessment of workers at coal-fred power plants. In addition, the findings can be used as a basic data for development of safety standard and guide of Natural Radiation Safety Management Act.

Electrothermal atomic absorption spectrometry was employed for analyses of nickel concentrations in urine samples from nickel-exposed workers in 10 occupational groups and from non-exposed workers in two control groups. Mean concentrations of nickel in urine were greatest in workers who were exposed to inhalation of aerosols of soluble nickel salts (e.g., workers in nickel plating operations and in an electrolytic nickel refinery). Less marked increases in urine nickel concentrations were found in groups of metal sprayers, nickel battery workers, bench mechanics and are welders. No significant increases in mean concentrations of nickel were found in urine samples from workers who performed grinding, buffing and polishing of nickel-containing alloys or workers in a coal gasification plant who employed Raney nickel as a hydrogenation catalyst. Measurements of nickel concentrations in urine are more sensitive and practical than measurements of serum nickel concentrations for evaluation of nickel exposures in industrial workers.

Turkish cultural heritage: a cup of coffee

Full Text Available Setting out a fabulous journey from a tiny bean, coffee is the stimulant of the heart and mind and a mysterious plant that strengthens friendship and also takes your tiredness away during the day. Although information on how and where the coffee came from is not clear, Sheikh Şazeli is regarded as the “father” by coffee makers. The word coffee originates from “Kaffa”, a primary coffee production center in Abyssinia, Africa, which can be considered the homeland of coffee. According to this consideration, in Abyssinia, coffee was consumed with bread; it was then pulped and brought to Yemen, and Yemeni people started to cultivate coffee. The word “kahve” in Turkish does not mean the coffee plant like its synonym in Arabic but means the beverage made by boiling. Turkish coffee is a blend of high-quality Arabic-type coffee beans, originating from Brazil and Central America and moderately roasted and ground finely. The way it is prepared differentiates Turkish coffee from others. This coffee was called Turkish coffee because of a new method of preparation invented by Turkish people where it is boiled in copper coffee pots. Turkish coffee that has spread around the world with this name has been an indispensable part of the cultural and social history of Turks.

Parents' reports of problem behaviors in 2,081 Dutch children, 3,127 Turkish children in Ankara and 833 Turkish immigrant children living in The Netherlands, aged 4-18 years, were compared. Dutch and Turkish versions of the Child Behavior Checklist (CBCL) were used. Immigrant children were scored higher than Dutch children on 6 of the 11 CBCL scales, most markedly on the Anxious/Depressed scale. Immigrant children were scored higher than Ankara children on five CBCL scales. However, these differences were much smaller than those found between immigrant and Dutch children. Furthermore, immigrant children's Total Problem scores did not differ from those for Ankara children. Turkish immigrant children have very similar patterns of parent-reported problem behaviors to children living in Turkey, although both groups of Turkish children showed higher levels of parent-reported problem behaviors than Dutch children. The higher scores for Turkish children on the Anxious/Depressed scale compared with their Dutch peers may be explained by cultural differences in parental perception of children's problem behaviors, as well as the threshold for reporting them, or by cultural differences in the prevalence of problems, for instance as the result of cross-cultural differences in child-rearing practice. More research is needed to test the degree to which Turkish immigrant parents tend to preserve their cultural characteristics and child-rearing practices in Dutch society.

2008-01-01

The effects of microwave receptor to coal (receptor/coal) ratio and the period of heating by microwave energy on the solubilization of Turkish coals in tetralin have been investigated. CuO was used as microwave receptor. The amount of receptor and the type of coal significantly affected the yield of liquid product. The addition of the CuO receptor caused to increase in the lignite conversions to oil fractions. The yield of THF soluble fraction increased in the presence of CuO receptor, however, due to catalytic effect of CuO, the yields of preasphaltene (PAS) and asphaltene (AS) decreased. The oil fractions were obtained from the experiments treated by microwave energy in the presence of 3/5 CuO/coal ratio and in the absence of receptor for 20 min liquefaction periods. The compositions of the oil fractions were determined by GC/MS. The composition of the oil fractions of the coals strongly depends on the type of coal. It was observed that the oil fractions contain oxygenated aromatic compounds in addition to condensed aromatic structures. Considerable amounts of 3,4-dihydro-1(2H)-naphthalenone (alpha-tetralone) were found in the oil fractions of lignites treated by microwave energy

1989-01-01

In 1984-1985, medical examinations consisting of a chest radiograph, spirometry test, and questionnaire on work history, respiratory symptoms, and smoking history were administered to 1,061 white males who were employed at 31 coal cleaning plants and strip coal mines in the anthracite coal region of northeastern Pennsylvania. The prevalence of radiographic evidence of International Labour Office (ILO) category 1 or higher small opacities was 4.5% in 516 men who had never been employed in a dusty job other than in surface coal mining. Among these 516 workers, all 4 cases of ILO radiographic category 2 or 3 rounded opacities and 1 case of large opacities had been employed as a highwall drill operator or helper. The prevalence of category 1 or higher opacities increased with tenure as a highwall drill operator or helper (2.7% for 0 y, 6.5% for 1-9 yr, 25.0% for 10-19 y, and 55.6% for greater than or equal to 20 y drilling). Radiographic evidence of small rounded opacities, dyspnea, and decreases in FEV1.0, FVC, and peak flow were significantly related to tenure at drilling operations after adjusting for age, height, cigarette smoking status, and exposures in dusty jobs other than in surface coal mining. However, tenure in coal cleansing plants and other surface coal mine jobs were not related to significant health effects. The apparent excess prevalence of radiographic small rounded opacities in anthracite surface coal mine drillers suggests that quartz exposures have been increased. Average respirable quartz concentrations at surface coal mine drilling operations should be evaluated to determine whether exposures are within existing standards, and dust exposures should be controlled

2016-01-01

The purpose of this cross-cultural study was to describe and compare US and Turkish children's observational knowledge of the day and night cycle and to identify similarities predicted by framework theory. Fifty-six (27 US and 29 Turkish) young children (ages 48-60 months) participated in the study. Semi-structured interviews were individually conducted, digitally recorded, transcribed, and analyzed using the constant comparative method. The results demonstrate that preschoolers from the two cultures are able to make comparable informal observations of the sky, and their observational knowledge includes many similarities, with one exception, as predicted by framework theory. US children were more likely to perform better than the Turkish children on the question about the time of observation for the moon. Although science concepts and skills are better represented in US early childhood education programs than the Turkish program, the results suggest that this advantage did not translate into performance differences between US and Turkish children.

Strengthening national coal transitions to raise climate ambition. Issue Brief. Part of the 'Coal Transitions: Research and Dialogue on the Future of Coal' Project

International Nuclear Information System (INIS)

Sartor, Oliver

2017-11-01

The issue of coal transitions is coming into focus in both national and international climate policy discussions. There are several drivers of this. At one level, the Paris Agreement marked a significant shift in the pace, scope and ambition of global climate change mitigation action. Consequently, it is now clear that coal will need to play a more and more diminished role in the global energy mix in the coming decades, despite carbon capture and storage (CCS) technologies. It is also increasingly clear that non-climate policy-related factors, such as rapid declines in the cost of renewable energy and battery storage, will continue to challenge the previously strong role of steam coal in the global energy mix (Randall, 2015). The business-as-usual scenario is therefore evolving quickly and the downside risks to coal demand appear to be increasing. The accumulation of these factors has in turn led to a call for an assurance of 'just transition', especially from stakeholders-notably coal sector workers and their communities-whose economic livelihoods depend on the future of an industry that will be in decline. In this context, parties to the UNFCCC will be called upon via the Facilitative Dialogue of 2018 to re-evaluate the adequacy progress and subsequently to revise their levels of ambition in their nationally determined contributions (NDCs). This moment presents an important opportunity for governments to raise the overall ambition of their policies on coal transition. But how should they do this? (author)

Many consortia and international projects have investigated the human genetic variation of a large number of ethno-geographic groups. However, populations with peculiar genetic features, such as the Turkish population, are still absent in publically available datasets. To explore the genetic predisposition to health-related traits of the Turkish population, we analyzed 34 genes associated with different health-related traits (for example, lipid metabolism, cardio-vascular diseases, hormone metabolism, cellular detoxification, aging and energy metabolism). We observed relevant differences between the Turkish population and populations with non-European ancestries (that is, Africa and East Asia) in some of the investigated genes (that is, AGT, APOE, CYP1B1, GNB3, IL10, IL6, LIPC and PON1). As most complex traits are highly polygenic, we developed polygenic scores associated with different health-related traits to explore the genetic diversity of the Turkish population with respect to other human groups. This approach showed significant differences between the Turkish population and populations with non-European ancestries, as well as between Turkish and Northern European individuals. This last finding is in agreement with the genetic structure of European and Middle East populations, and may also agree with epidemiological evidences about the health disparities of Turkish communities in Northern European countries.

Using proximate analysis to characterize airborne dust generation from bituminous coals

Energy Technology Data Exchange (ETDEWEB)

Page, S.J.; Organiscak, J.A.

2005-11-01

Prolonged exposure to airborne respirable coal dust is responsible for coal workers pneumoconiosis (CWP), commonly called black lung. Health research studies have identified that the prevalence and severity of CWP are directly related to both the amount of dust exposure and the coal rank. The amount of airborne respirable dust (ARD) smaller than 10 micrometers generated from breakage of different coals varies widely. To investigate the cause, researchers for the National Institute for Occupational Safety and Health (NIOSH) have conducted experiments to identify the causes of airborne respirable dust liberation. Laboratory crushing experiments were conducted on a range of low to high volatile bituminous coals from eight mines. The results indicate that the proximate analysis of a coal sample can provide a very good indicator of the potential for a dust problem. For application to the coal mining, processing, and utilization industries, data from 977 US coal seams compiled by the Department of Energy (DoE) has been used to calculate this dust generation potential from an equation based on the NIOSH measured data. A simple procedure for this calculation is provided. 1 fig.

2012-08-01

The present study assessed the psychometric properties of the Frustration Discomfort Scale for Turkish college students. The Frustration Discomfort Scale (FDS), Procrastination Assessment Scale-Student, and Rosenberg Self-Esteem Scale were administered to a sample of 171 (98 women, 73 men) Turkish college students. The results of the confirmatory factor analysis yielded fit index values demonstrating viability of the four-dimensional solution as in the original. Findings also revealed that, as predicted, the Discomfort Intolerance subscale of Turkish FDS was most strongly correlated with procrastination. Overall results provided evidence for the factor validity and reliability of the Turkish version of the scale for use in a Turkish population.

Traditional municipal services are not successful at reaching Turkish seniors. Compared to native Germans Turkish seniors have a lower social participation. Do native language groups hosted by a German organization promote the social participation of Turkish seniors? How does social participation take place in the ZWAR networks (between work and retirement; a project to strengthen social participation of seniors) and which factors promote or reduce social participation? Qualitative structuring content analysis of two group discussions, which were based on guided interviews. The social participation of Turkish-speaking seniors was strengthened on three levels: (1) through regular meetings of the Turkish ethnic group social relationships were promoted and German language skills and other skills were improved. Through mutual sharing and understanding of the stressors specific to migration, emotional support was provided. The sharing of mutual cultural and linguistic backgrounds created a sense of community and meetings were perceived as an antidote to migrants' exhausting lives in German society. (2) At the organizational level, participation was promoted through extensive group events. Regardless of their cultural background all participants identified as equal ZWAR members. The ZWAR project functioned as an umbrella organization for participation in the intercultural context. (3) Participation in community events created contacts with community stakeholders and fostered volunteer work. Hence, participants were able to use their skills, and therefore broaden their horizons. Turkish ZWAR networks promoted the social participation of members because integration with their ethnic group reduced access barriers, broadened members' scopes of action, and created new opportunities for participation.

Modelling and forecasting Turkish residential electricity demand

International Nuclear Information System (INIS)

Dilaver, Zafer; Hunt, Lester C

2011-01-01

This research investigates the relationship between Turkish residential electricity consumption, household total final consumption expenditure and residential electricity prices by applying the structural time series model to annual data over the period from 1960 to 2008. Household total final consumption expenditure, real energy prices and an underlying energy demand trend are found to be important drivers of Turkish residential electricity demand with the estimated short run and the long run total final consumption expenditure elasticities being 0.38 and 1.57, respectively, and the estimated short run and long run price elasticities being -0.09 and -0.38, respectively. Moreover, the estimated underlying energy demand trend, (which, as far as is known, has not been investigated before for the Turkish residential sector) should be of some benefit to Turkish decision makers in terms of energy planning. It provides information about the impact of past policies, the influence of technical progress, the impacts of changes in consumer behaviour and the effects of changes in economic structure. Furthermore, based on the estimated equation, and different forecast assumptions, it is predicted that Turkish residential electricity demand will be somewhere between 48 and 80 TWh by 2020 compared to 40 TWh in 2008. - Research highlights: → Estimated short run and long run expenditure elasticities of 0.38 and 1.57, respectively. → Estimated short run and long run price elasticities of -0.09 and -0.38, respectively. → Estimated UEDT has increasing (i.e. energy using) and decreasing (i.e. energy saving) periods. → Predicted Turkish residential electricity demand between 48 and 80 TWh in 2020.

Since the sixties of the last century, many people from Morocco and Turkey have migrated into the Netherlands. In the last decade, Moroccan and Turkish patients have found their way to organizations for mental health care. However, they often drop out of treatment. Problems in the communication with therapists and different expectations regarding treatment seem to be causal factors for the early drop-out of therapy. In the Netherlands as in other countries courses have been developed for training cultural competence of therapists. Yet, up to now, the effectiveness of increased cultural competence of therapists in reducing drop-out of treatment has not been studied. A randomized clinical trial was started in January 2010. Moroccan and Turkish adult patients who are referred to our outpatient clinics for mood and anxiety disorders are randomly assigned to mental health workers who are trained in a cultural module and to those who are not. The therapists have been trained in the Cultural Formulation and in techniques bridging the (cultural) gap between them and their Moroccan and Turkish patients. The target number of participants is 150 patients, 75 for each group. Drop-out of treatment is the primary outcome measure. Secondary outcome measures are no-show and patients' perspective of care. The study will give an answer to the question whether increasing cultural competence of therapists reduces drop-out of treatment in Moroccan and Turkish outpatients with depressive and anxiety disorders.

Full Text Available Today, employment security is a most important need for wage-earners, especially in developing countries which have a high rate of unemployment, where firing workers is a way to lower wages. Because of that there are some provisions of international regulations that need to be addressed. Job security and restrictions on firing figure prominently in much national labour legislation. These provisions and principles are underlined in ILO Recommendation No. 119 and Convention No. 158. In this paper, attention is focused on ILO Convention No. 158 and its repercussions on Turkish labour law.

Alleman, J.E.; Clikeman, F.M.; Skronski, T.

1998-01-01

One of the important environmental issues raised recently in regard to coal ash reuse for highway construction purposes (e.g., embankment development) is that of worker, and public, exposure to radiation which might possibly be emitted by these types of residues. This research project subsequently addressed the associated issue of radiation emission by coal ash residuals generated within the State of Indiana, covering both fly ash and bottom ash materials. Samples were obtained at sixteen different coal-fired power generating facilities within Indiana and subjected to quantitative analysis of their associated gamma-ray emission levels. After identifying the responsible radionuclides, a conservative approximation was then developed for the worst-case potential occupational exposure with construction employees working on this type of high-volume, coal ash embankment. In turn, these potential emissions levels were compared to those of other traditional construction materials and other common sources

Assessment of risk of accident at work as an indicator of safe behaviour of workers

Energy Technology Data Exchange (ETDEWEB)

Pisiewicz, K

1978-10-01

In 1977 the Psychology and Sociology Research Development Unit of the Central Mining Institute carried out research on the influence of assessment of the accident risk on the safe behaviour of workers. 450 workers employed at the longwall faces in 6 coal mines with various accident rates were questioned. It was found that a low assessment of risk favours hazardous operations, contrary to the principles of work safety, while a high assessment of the risk does not favour hazardous operations. Miners employed in coal mines with high accident rates tend to a low assessment of accident risk (arithmetic mean x 48.54) in comparison to miners from mines with low accident rates (arithmetic mean x 53.68). It was also found that the arithmetic mean of assessment of risks among workers who had had an accident at work is lower (x 50.3) than among workers who had not yet had an accident at work (x 55.32).

Safety trends in small-scale coal mines in developing countries with particular reference to China, India and Pakistan

Small-scale mining for coal is practiced all over the world. But major proportions of these mines are located in developing countries in Asia. China, India and Pakistan are the main producers of coal from small- scale mines. Due to prevailing poor safety conditions in these mines, a large number of workers receive injuries ranging from minor to fatal. Gas explosions/outbursts, roof falls, material handling, etc. are the main causes of majority of accidents occurring in small-scale mines. In China, thousands of workers are killed due to gas explosions/outbursts every year. Lack of financial resources, inadequate education and training of workers, contractual labour systems and lack of commitment to improve safety and health are the reasons that mainly contribute to the poor safety performance in this sector of mining.

A good understanding of the learning styles of students is necessary for optimizing the quality of the learning process. There are few studies in Turkey on the subject of the learning characteristics of medical students. The aim of this study was to define the learning patterns of Turkish medical students based on the Turkish version of Vermunts Inventory of Learning Styles (ILS). The Turkish version of the ILS was developed and administered to 532 medical students. Learning patterns were investigated using factor analysis. Internal consistencies of scales ranged from 0.43 to 0.80. The Turkish version of the ILS identified four learning styles among medical students. In comparing the pre-clinical and clinical phases of medical students related to mental models of learning, statistically significant differences (p learning characteristics: lack of regulation; certificate; self-test and ambivalent orientation; intake of knowledge; and use of knowledge. The Turkish version of the ILS can be used to identify learning styles of medical students. Our findings indicate an intermediate position for our students on a teacher-regulated to student-regulated learning continuum. A variety of teaching methods and learning activities should be provided in medical schools in order to address the range of learning styles.

The European Coal Market: Will Coal Survive the EC's Energy and Climate Policies?

conventional reserves of fossil fuels. Coal contributes to the economic activity and employment in the region. The EU mining industry employs 260,000 workers (direct jobs) and the turnover of the whole coal industry is estimated at Euros 25 billion a year. Coal prices, despite their rising trend in the past few years, are much lower than competing fuels: half the price of natural gas imported in Europe. As coal ensures safe, reliable, affordable and sustainable energy for all, it will be very much needed in the years to come. However, coal is proscribed in a CO 2 -free environment. Its combustion in thermal power plants - its main outlet in Europe - emits twice as much CO 2 as gas plants. Although a lot of R and D work is done to capture CO 2 emissions from coal plants and store it, no zero emission commercial plants have yet started operation. Several CCS projects have been delayed, or even cancelled, in the past few years due to regulatory uncertainties, a lack of funding and public opposition to CO 2 storage. The current European economic crisis and the large sovereign debts have also reduced public funding in CCS projects. The future of coal in Europe is therefore very uncertain. Will CCS development allows it to remain a fuel of choice, given large available reserves at low prices, compared with competing energy sources? Or will coal disappear from the European energy mix? How fast will the decline in European coal production be? This report looks at these issues and highlights some facts, trends and regulation that may affect the supply and demand of coal in the future. The analysis concentrates on steam coal used to generate electricity, since the power generation sector is by far the largest user of coal in Europe. The first part of this report looks at the European coal market region-wide. Chapter 1 describes the EU coal market in the global context. Chapter 2 analyses the significance of the European coal mining industry and its future after the end of state aid

Full Text Available ABSTRACT Objective: The aim of this study was to clarify the morphological differences in the mandibular arches of Turkish and North American white subjects. Methods: The sample included 132 Turkish (34 Class I, 58 Class II, and 40 Class III and 160 North American (60 Class I, 50 Class II, and 50 Class III subjects. The most facial portion of 13 proximal contact areas was digitized from photocopied images of patients' mandibular dental arches. Clinical bracket points were calculated for each tooth based on mandibular tooth thickness data. Four linear and two proportional measurements were taken. The subjects were grouped according to arch form types (tapered, ovoid and square in order to have frequency distribution compared between ethnic groups in each Angle classification. Results: The Turkish group showed significantly lower molar depth and more significant molar width-depth (W/D ratio in all three Angle classifications. On the other hand, the Turkish group also showed a significantly larger intercanine width in Class III malocclusion and intermolar width in Class II malocclusion. The most frequent arch forms seen were the ovoid arch form in the Turkish group and the tapered form in the white group. Conclusions: Our results demonstrate that when treating Turkish patients, one should expect to use preformed ovoid arch form orthodontic wires in a significant percentage of patients.

Full Text Available Being one of the four basic language skills, reading has a great importance in teaching Turkish to foreigners. It is required to develop reading skills to develop vocabulary. There have been some problems in teaching Turkish as second language. These problems are generally related to difference in alphabet, inadequacy of the sources used in teaching Turkish, methods and techniques used and the texts used. The basic sources used in teaching Turkish to foreigners are texts. This study aims at determination of the opinions of students in Gaziosmanpaşa University and Ondokuz Mayıs University Turkish Education and Application Center (TOMER concerning Turkish reading texts. General browsing method was used in the study. The questionnaire comprising of 24 items was applied to 25 students in beginner level and 7 students in advanced level. With this study, it is foreseen to arrange the texts being the key stone according to the wishes of and in compliance with the levels of students; giving importance to pre-reading, reading and post-reading activities and including questions with short-answer about the text as well as questions to develop high level skills.

The Production of Turkish Relative Clauses in Second Language Acquisition: Overcoming Student Difficulties

Anjel Toczu

2010-01-01

Full Text Available This study focuses on teaching relative clauses (R.Cs in Turkish, a left-branching language, and discusses the relative difficulty of producing RCs in Turkish by English-speaking learners by investigating whether the production of subject relative clauses in Turkish is easier than that of the object relative clauses. It also offers suggestions as to how to help learners overcome these difficulties. Turkish and English belong to two different language families, Altaic and Inda-European respectively. This study lends further insight that Turkish does not have RCs similar to those found in Inda-European languages. Instead, in Turkish RCs comprise nominalized verbs and participles. The characteristics of Turkish are also explained such as its word order, agglutinating morphology, vowel and consonant harmony rules as well as case markers indicating grammatical relations between sentence constituents, which shed light to our understanding of RCs in Turkish.

Several theories have sought to explain the motivations for handgun possession and the relationship with personality. Perception of handguns also has cultural variations. The aim of the study is to evaluate handgun license applicants' personality profiles. 109 handgun license applicants were included in the study. Temperament and Character Inventory (TCI) scores of the applicants were recorded. Scores were compared with Turkish and American normative data for the Inventory. The study group had significantly lower subscores on novelty seeking, harm avoidance, and higher subscores on reward dependence and persistence compared to Turkish norms and significantly lower subscores on novelty seeking, reward dependence, and self-directedness compared to American norms. Results indicate that Turkish handgun license applicants' personality features are more similar to American norms.

We have used small angle neutron scattering (SANS) to investigate the differences in methane and hexane penetration in pores in bituminous coal samples from the U.S., Canada, South Africa, and China, and maceral concentrates from Australian coals. This work is an extension of previous work that showed consistent differences between the extent of penetration by methane into 10–20 nm size pores in inertinite in bituminous coals from Australia, North America and Poland.In this study we have confirmed that there are differences in the response of inertinite to methane and hexane penetration in coals sourced from different coal basins. Inertinite in Permian Australian coals generally has relatively high numbers of pores in the 2.5–250 nm size range and the pores are highly penetrable by methane and hexane; coals sourced from Western Canada had similar penetrability to these Australian coals. However, the penetrability of methane and hexane into inertinite from the Australian Illawarra Coal Measures (also Permian) is substantially less than that of the other Australian coals; there are about 80% fewer 12 nm pores in Illawarra inertinite compared to the other Australian coals examined. The inertinite in coals sourced from South Africa and China had accessibility intermediate between the Illawarra coals and the other Australian coals.The extent of hexane penetration was 10–20% less than CD4 penetration into the same coal and this difference was most pronounced in the 5–50 nm pore size range. Hexane and methane penetrability into the coals showed similar trends with inertinite content.The observed variations in inertinite porosity between coals from different coal regions and coal basins may explain why previous studies differ in their observations of the relationships between gas sorption behavior, permeability, porosity, and maceral composition. These variations are not simply a demarcation between Northern and Southern Hemisphere coals.

2007-01-01

Small and medium size enterprises (SMEs) have an important role in the Turkish economy because of the workforce involved. According to the size of the industrial facilities, there are different cost components related to the total production costs. Energy cost is usually a small portion of the total production cost, but the Turkish industrial sector comprises approximately 35% of Turkey's total energy consumption and 98.8% of the total number of enterprises in Turkey constitutes the SMEs. Because of the uncertainty of energy costs in the world, it is important to take preventive measures to reduce energy costs and increase efficiencies in industry and consequently in SMEs. In this paper, medium sized enterprises are taken into consideration essentially. Because of getting homogeneity, enterprises with the number of workers between 100 and 200 in the metallic goods industry have been considered in the survey. Energy management includes increasing the profitability by reduced operational costs, and it is also a potential for improving market share. Many different evaluation models have been published in the energy management literature. However, there have not been so many systematic approaches to compare the relative efficiency of the systems. Data envelopment analysis (DEA) is a special linear programming model for deriving the comparative efficiency of multiple-input multiple-output decision making units (DMUs). An evaluation of energy efficiency in 20 medium sized companies has been conducted, and the results are discussed in this paper

Full Text Available Object: In the most general sense, guilt is conceptualized as a strong, intense and negative emotion that quickly emerges when people do not live up according to internal values, judgements and social standards or violate them. The aim of the present study was to investigate the factor structure of Guilt Inventory that developed by Kugler and Jones with confirmatory and explanatory factor analyses and reevaluate the psychometric properties of the new Turkish form in depression and non-clinical samples. Methods: For this purpose, 448 university students, 107 healthy controls and 56 adults diagnosed with depression were asked to fill out the questionnaire set consisted of the Guilt Inventory, Beck Depression Inventory, Disgust Scale- Revised Form and The State-Trait Anxiety Inventory-State Anxiety Form.Results: According to the results, original form of Guilt Inventory did not work at the desired level in Turkish culture. Confirmatory and exploratory factor analyzes revealed that the new form with 35 items and 3 subscales works much more appropriately. The analyses of group comparison and correlations with other scales indicated that Turkish version of the Guilt Inventory had satisfactory convergent, divergent and criterion validity. Additively, internal consistency, item-total correlations and Guttman split-half reliability coefficients showed that the Turkish form of Guilt Inventory had good reliability values which were comparable to the original version of the scale. Discussion: In conclusion, results revealed that the Turkish version of Guilt Inventory is a reliable and valid measurement tool.

Objective: To understand the prevalence rate and correlative factors of dislipidemia among Shanxi coal miners and to provide evidence for the development of programs on dislipidemia prevention. Methods: We investigated 1 337 mine workers from a Coal Group in April 2016 and collected data related to their blood biochemistry. We then classified the types in accordance with the diagnostic criteria of " Guidelines for prevention and treatment of dyslipidemia in Chinese adults (2007)" , using χ (2) test and unconditional logistic regression model for analysis. Results: The overall prevalence rate of Dislipidemia was 59.1% (790/1 337), with males as 60.4% (708/1 173) and females as 50.0%(82/164) while males appeared higher ( χ (2)=6.386, P dislipidemia ( χ (2)=7.117, P dislipidemia ( P dislipidemia. Conclusion: Among the coal mine workers, those who were males, aged from 20 to 34, having high blood pressure (systolic blood pressure abnormalities) or with high BMI (≥24.0 kg/m(2)) need to be taken special attention on care and prevention of dislipidemia.

Are underground coal miners satisfied with their work boots?

Science.gov (United States)

Dobson, Jessica A; Riddiford-Harland, Diane L; Bell, Alison F; Steele, Julie R

2018-01-01

Dissatisfaction with work boot design is common in the mining industry. Many underground coal miners believe their work boots contribute to the high incidence of lower limb injuries they experience. Despite this, the most recent research to examine underground coal mining work boot satisfaction was conducted over a decade ago. This present study aimed to address this gap in the literature by assessing current mining work boot satisfaction in relation to the work-related requirements for underground coal mining. 358 underground coal miners (355 men; mean age = 39.1 ± 10.7 years) completed a 54-question survey regarding their job details, work footwear habits, foot problems, lower limb and lower back pain history, and work footwear fit and comfort. Results revealed that underground coal miners were not satisfied with their current mining work boots. This was evident in the high incidence of reported foot problems (55.3%), lower back pain (44.5%), knee pain (21.5%), ankle pain (24.9%) and foot pain (42.3%). Over half of the underground coal miners surveyed believed their work boots contributed to their lower limb pain and reported their work boots were uncomfortable. Different working roles and environments resulted in differences in the incidence of foot problems, lower limb pain and comfort scores, confirming that one boot design cannot meet all the work-related requirements of underground coal mining. Further research examining the interaction of a variety of boot designs across the different underground surfaces and the different tasks miners perform is paramount to identify key boot design features that affect the way underground coal miners perform. Enhanced work boot design could improve worker comfort and productivity by reducing the high rates of reported foot problems and pain amongst underground coal miners. Copyright © 2017 Elsevier Ltd.

Progress of fossil fuel science

Energy Technology Data Exchange (ETDEWEB)

Demirbas, M.F.

2007-07-01

Coal is the most abundant and widely distributed fossil fuel. More than 45% of the world's electricity is generated from coal, and it is the major fuel for generating electricity worldwide. The known coal reserves in the world are enough for more than 215 years of consumption, while the known oil reserves are only about 39 times of the world's consumption and the known natural gas reserves are about 63 times of the world's consumption level in 1998. In recent years, there have been effective scientific investigations on Turkish fossil fuels, which are considerable focused on coal resources. Coal is a major fossil fuel source for Turkey. Turkish coal consumption has been stable over the past decade and currently accounts for about 24% of the country's total energy consumption. Lignite coal has had the biggest share in total fossil fuel production, at 43%, in Turkey. Turkish researchers may investigate ten broad pathways of coal species upgrading, such as desulfurization and oxydesulfurization, pyrolysis and hydropyrolysis, liquefaction and hydroliquefaction, extraction and supercritical fluid extraction, gasification, oxidation, briquetting, flotation, and structure identification.

The Turkish version of the Perceived Stress Scale (T-PSS-10) measures the extent to which situations in one's life are appraised as stressful. The purpose of this study was to evaluate the measurement structure of T-PSS-10. Two-hundred and thirty-five Turkish university students (93 men and 142 women) completed the T-PSS-10, the Patient Health Questionnaire-9 (PHQ-9), the General Anxiety Disorder 7-Item Scale (GAD-7), and the Inventory of Common Problems (ICP). Confirmatory factor analysis results indicated that a one-factor model did not fit the data, whereas a two-factor correlated model (stress related self-efficacy beliefs, stress related feelings of helplessness) provided a better fit between the model and the data. Significant moderate correlations were found for the stress-related self-efficacy beliefs and stress-related feelings of helplessness factors with depression, anxiety, academic difficulty, relationship problems and health problems. The internal consistency reliability coefficients for the stress-related self-efficacy beliefs and stress-related feelings of helplessness factors were 0.68 and 0.85, respectively. This study provided support for the reliability and validity of T-PSS-10 suggesting that it can be used as a screening instrument by health professionals working with Turkish college students.

Human factors comprise one of the important reasons leading to the casualty accidents in coal mines. The aim of this study was to analyze the relationships among musculoskeletal disorders (MSDs), personality traits, psychological distress, and accident proneness of coal miners. There were 1500 Chinese coal miners surveyed in this study. Among these miners, 992 valid samples were obtained. The study surveyed the MSDs, personality traits, psychological distress, and accident proneness of coal miners with MSDs Likert scale, Eysenck personality questionnaire, Symptom Checklist-90 (SCL-90) scale, and accident proneness questionnaire, respectively. The highest MSDs level was found in the waist. The increasing working age of the miners was connected with increased MSDs and psychological distress. Significant differences in MSDs and psychological distress of miners from different types of work were observed. Coal miners with higher MSDs had higher accident proneness. Coal miners with higher neuroticism dimension of Eysenck personality and more serious psychological distress had higher accident proneness. Phobic anxiety, paranoid ideation and psychoticism dimension of psychological distress were the three most important indicators that had significant positive relationships with accident proneness. The MSDs, neuroticism dimension, and psychological distress of the coal mine workers are important to work safety and require serious attention. Some implications concerning coal mine safety management in China were provided.

Following the increasing demand of coal for power generation, activity concentrations of primordial radionuclides were determined in Nigerian coal using the gamma spectrometric technique with the aim of evaluating the radiological implications of coal utilization and exploitation in the country. Mean activity concentrations of 226Ra, 232Th, and 40K were 8.18±0.3, 6.97±0.3, and 27.38±0.8 Bq kg-1, respectively. These values were compared with those of similar studies reported in literature. The mean estimated radium equivalent activity was 20.26 Bq kg-1 with corresponding average external hazard index of 0.05. Internal hazard index and representative gamma index recorded mean values of 0.08 and 0.14, respectively. These values were lower than their respective precautionary limits set by UNSCEAR. Average excess lifetime cancer risk was calculated to be 0.04×10−3, which was insignificant compared with 0.05 prescribed by ICRP for low level radiation. Pearson correlation matrix showed significant positive relationship between 226Ra and 232Th, and with other estimated hazard parameters. Cumulative mean occupational dose received by coal workers via the three exposure routes was 7.69 ×10−3 mSv y-1, with inhalation pathway accounting for about 98%. All radiological hazard indices evaluated showed values within limits of safety. There is, therefore, no likelihood of any immediate radiological health hazards to coal workers, final users, and the environment from the exploitation and utilization of Maiganga coal.

Impacts on human health from the coal and nuclear fuel cycles and other technologies associated with electric power generation and transmission

International Nuclear Information System (INIS)

Radford, E.P.

1980-01-01

Major public health impacts of electric power generation and transmission associated with the nuclear fuel cycle and with coal use are evaluated. Only existing technology is evaluated. The only health effects of concern are those leading to definable human disease and injury. Health effects are scaled to a nominal 1000 Megawatt (electric) plant fueled by either option. Comparison of the total health effects to the general public gives: nuclear, 0.03 to 0.05 major health effects per 1000 MWe per year; coal, 0.7 to 3.7 per 1000 MWe per year. Thus for the general public the health risks from the coal cycle are about 50 times greater than for the nuclear cycle. Health effects to workers in the industry are currently quite high. For the nuclear cycle, 4.6 to 5.1 major health impacts per 1000 MWe per year; for coal, 6.5 to 10.9. The two-fold greater risk for the coal cycle is primarily due to high injury rates in coal miners. There is no evidence that electrical transmission contributes any health effects to the general public, except for episodes where broken power lines come in contact with people. For power line workers, the risk is estimated at 0.1 serious injury per 1000 MWe per year

Full Text Available This study analyses the behavior and the preferences of the Greek learners of Turkish language, who use a particular e-learning website in parallel with their studies, namely: http://turkish.pgeorgalas.gr. The website offers free online material in Greek and English language for learning the Turkish language and grammar. The traffic of several modules of the website has been measured, examined and analyzed. The research was carried out between the years 2010- 2011 and included the analysis of several million clicks. The results show particular attitudes, habits and preferences throughout the e-learning process. There is a preference of users to exercises against theory. Fast cross-link exercises are preferred to slower “fill in” ones. During the weekends, visitors tend to use less e-learning facilities and select more light activities than the rest days of the week. Society trends and fashions like TV serials have a serious impact to the number of people who decide to learn a new foreign language, in particular Turkish. There is a strong preference of the audience to use online TV against online radio facilities for language practice. The subjects that Greek learners of Turkish language spend more time are verbs conjugation and vocabulary learning. They focus on elementary grammar subjects like the Alphabet, the numbers and the formation of plural. Finally, they try to learn the syntax of Turkish language through sentence structure puzzles and give priority to special grammar issues like noun compounds that are not present in Greek language.

James Craufurd Gregory, 19th century Scottish physicians, and the link between occupation as a coal miner and lung disease.

Donaldson, K; Wallace, W A; Elliot, T A; Henry, C

2017-09-01

By the mid-19th century about 200,000 miners were employed in a UK coal mining industry still growing with the advances of the Industrial Revolution. Coal miners were long known to suffer poor health but the link to inhaling dust in the mines had not been made. In 1813 George Pearson was the first to suggest that darkening of lungs seen in normal individuals as they aged was caused by inhaled soot from burning oil, candles and coal, which were the common domestic sources of heat and light. In 1831 Dr James Craufurd Gregory first described black pigmentation and disease in the lungs of a deceased coal miner and linked this to pulmonary accumulation of coal mine dust. Gregory hypothesised that the black material seen at autopsy in the collier's lungs was inhaled coal dust and this was confirmed by chemical analysis carried out by Professor Sir Robert Christison. Gregory suggested that coal dust was the cause of the disease and warned physicians in mining areas to be vigilant for the disease. This first description of what came to be known as 'coal worker's pneumoconiosis' sparked a remarkable intellectual effort by physicians in Scotland, culminating in a large body of published work that led to the first understandings of this disease and its link to coalblackened lungs. This paper sets out the history of the role of Scottish physicians in gaining this understanding of coal worker's pneumoconiosis. It describes Gregory's case and the lung - recently discovered in the pathology collection of the Surgeons' Hall Museums, Edinburgh, where it has lain unnoticed for over 180 years - on which Gregory based his landmark paper.

In the face of the frequent occurrence of coal mine safety accidents, this paper analyses the relationship between central and local governments, coal mining enterprises and miners from the perspective of multi - group game. In the actual production, the decision of one of the three groups can affect the game strategy of the other of the three, so we should assume the corresponding game order. In this order, the game analysis of the income and decision of the three is carried out, and the game decision of the government, the enterprise and the workers is obtained through the establishment of the benefit matrix and so on. And then on the existing system to optimize the coal industry regulation proposed practical recommendations to reduce the frequency of industry safety accidents, optimize the industry production environment.

Psychometric Properties of the Turkish version of Looming Maladaptive Style Questionnaire (LMSQ (Turkish

Directory of Open Access Journals (Sweden)

Ayşe Altan Atalay

2018-03-01

Full Text Available Objectives: Most of the studies that examine cognitive vulnerability tend to focus on cognitive vulnerability for depression and explain anxiety through its intersection with depression. Looming Cognitive Style (LCS was suggested as a cognitive vulnerability model that is specific for anxiety. According to the model, people who have looming vulnerability tend to evaluate the threats coming from the environment as more overwhelming than they actually are and are constantly hypervigilant to the threat cues that may come from the environment. This pattern plays an important role in both generation and maintenance of anxiety disorders. A two-factor looming vulnerability scale was developed to assess looming cognitive style and the present study aims to adapt the scale into Turkish and examine its psychometric characteristics. Method: The sample is composed of 657 university students between the ages of 18 and 29. The participants were administered LMSQ-R as well as scales that assess anxiety, depression, and worry. Results: Confirmatory factor analysis results supported the original factor structure of the scale providing two distinct, but correlated factors as social and physical looming. In addition to that, total score and subscale scores had moderate to high correlations with other study variables and reliability scores appearing close to the original form provides support for the reliability of the scale. Conclusion: The Turkish version of the LMSQ-R is a reliable and valid scale that can be used with Turkish population.

Activator protein-1 (AP-1) and nuclear factor of activated T cells (NFAT) are two important transcription factors responsible for the regulation of cytokines, which are involved in cell proliferation and inflammation. Coal workers' pneumoconiosis (CWP) is an occupational lung disease that may be related to chronic inflammation caused by coal dust exposure. In the present study, we demonstrate that coal from the Pennsylvania (PA) coalmine region, which has a high prevalence of CWP, can activate both AP-1 and NFAT in JB6 mouse epidermal cells. In contrast, coal from the Utah (UT) coalmine region, which has a low prevalence of CWP, has no such effects. The PA coal stimulates mitogen-activated protein kinase (MAPK) family members of extracellular signal-regulated kinases (ERKs) and p38 MAPK but not c-Jun-NH(2)-terminal kinases, as determined by the phosphorylation assay. The increase in AP-1 by the PA coal was completely eliminated by the pretreatment of cells with PD98059, a specific MAPK kinase inhibitor, and SB202190, a p38 kinase inhibitor, further confirming that the PA coal-induced AP-1 activation is mediated through ERKs and p38 MAPK pathways. Deferoxamine (DFO), an iron chelator, synergistically enhanced the PA coal-induced AP-1 activity, but inhibited NFAT activity. For comparison, cells were treated with ferrous sulfate and/or DFO. We have found that iron transactivated both AP-1 and NFAT, and DFO further enhanced iron-induced AP-1 activation but inhibited NFAT. These results indicate that activation of AP-1 and NFAT by the PA coal is through bioavailable iron present in the coal. These data are in agreement with our previous findings that the prevalence of CWP correlates well with levels of bioavailable iron in coals from various mining regions.

Psychological problems of Turkish migrants in West Germany.

Science.gov (United States)

Suzuki, P T

1981-04-01

The path of adjustment for Turkish migrants--young and old, male and female--to a highly industralized Western society is a difficult one fraught with parlous conditions over which they have little control, largely because of Germany attitudes toward and treatment of Gastarbeiter in general and Turks in particular. Holding other variables constant, the psychological problems discerned as unique to Turkish Gastarbeiter are on the rise. These problems are of such a dimension that they clearly show the urgent need for Germans, the German government and its agencies, the Turkish government, and mental health professionals to come to grips with the existing situation. A program should be devised that (1) prepares the Turks for their new life before emigration; (2) educate the host country to lessen prejudice and heighten appreciation of the alien culture.

Estimation of impact from natural sources of radiation sources in two non nuclear plant workers and nearby residents

International Nuclear Information System (INIS)

Sousa, Wanderson de Oliveira

2005-09-01

Naturally occurring radioactive materials, often referred to as NORM, are and always have been a part of our world. Our planet 'Earth' and its atmosphere contain many different types of naturally occurring radioactive species , mainly minerals containing radionuclides of uranium and thorium decay series. Human activities for e x p l o i t a t i o n of mineral resources as mining, necessarily, do not enhance the concentration of NORM in products , by-products or residues, but can be a concern, simply due to the increased potential for human exposure. The goal of this work is to assess the impact of the presence of two non-nuclear plants (coal mining and monazite extraction plant) to workers and general population living in the vicinities of plants, by calculating their internal exposure to natural radionuclides . Excreta samples (urine and feces) were collected from workers and inhabitants of the two small towns where workers reside. The activities of 238 U, 234 U ( o n l y in feces), 226 Ra , 210 Pb and 210 Po (only in urine),- present in the samples were determined. The results of daily excretion in urine and feces of the groups, indicate that workers from coal mining, are exposed to natural radionuclides by inhalation and ingestion. The intake of some radionuclides ( 238 U and 210 Po ) are influenced by the professional activity . The results also indicate a chronic intake of 226 Ra by workers of the coal mining and their neighbors. Workers from the monazite extraction plant and inhabitants of the vicinity of the plant are exposed, mainly by ingestion. The intake through diet is the major source of incorporation of natural radionuclides. (author)

Objectives To study trends in height of Turkish and Moroccan immigrant children living in The Netherlands, to investigate the association between height and background characteristics in these children, and to calculate height-for-age-references data for these groups. Design Nationwide cross-sectional data collection from children aged 0 to 18 years by trained professionals in 1997 and 2009. The study population consisted of 2,822 Turkish 2,779 Moroccan, and 13,705 Dutch origin children in 1997and 2,548 Turkish, 2,594 Moroccan, and 11,255 Dutch origin children in 2009. Main outcome measures: Mean height in cm, and mean height standard deviation scores. Results In 2009, mean height at the age of 18y was similar for Turkish and Moroccan children: 177 cm for boys and 163 cm for girls, which was 2 to 3 cm taller than in 1997. Still, Turkish and Moroccan adolescents were 5.5 cm (boys) to 7 cm (girls) shorter than their Dutch peers. No significant differences were found in mean height standard deviation scores across the educational level of the parents, geographical region, primary language spoken at home, and immigrant generation. Conclusions While the secular height increase in Dutch children came to a halt, the trend in Turkish and Moroccan children living in The Netherlands continued. However, large differences in height between Turkish and Moroccan children and Dutch children remain. We found no association with the background characteristics. We recommend the use of the new growth charts for children of Turkish and Moroccan origin who have a height-for-age below -2SD on the growth chart for Dutch children. PMID:25938671

The enrichment of coalbed methane (CBM) and the outburst of gas in a coal mine are closely related to the nanopore structure of coal. The evolutionary characteristics of 12 coal nanopore structures under different natural deformational mechanisms (brittle and ductile deformation) are studied using a scanning electron microscope (SEM) and low-temperature nitrogen adsorption. The results indicate that there are mainly submicropores (2~5 nm) and supermicropores (coal and mesopores (10~100 nm) and micropores (5~10 nm) in brittle deformed coal. The cumulative pore volume (V) and surface area (S) in brittle deformed coal are smaller than those in ductile deformed coal which indicates more adsorption space for gas. The coal with the smaller pores exhibits a large surface area, and coal with the larger pores exhibits a large volume for a given pore volume. We also found that the relationship between S and V turns from a positive correlation to a negative correlation when S > 4 m2/g, with pore sizes coal. The nanopore structure (coal. PMID:25126601

Photoluminescence of Turkish purple jade (turkiyenite)

2012-01-01

The purple-colored unique gem material is only found in the Harmancık (Bursa) region of the western Anatolia (Turkey). Therefore, it is specially called “Turkish purple jade or turkiyenite” on the worldwide gem market. Even though its jadeite implication is the principal constituent, the material cannot be considered as a single jadeite mineral since other implications are quartz, orthoclase, epidote, chloritoid and phlogopite minerals. Even if the analytical methods are used to characterize and identify the Turkish purple jade samples in detail, the luminescence spectra, especially photoluminescence features regarding to composite mineral implications of the material are important because of the existence the numerous characteristic broad and intensive luminescence bands in the samples. We can state that the UV-irradiation luminescence centers as photoluminescence (PL) are due to the overall signals in the Turkish purple jade samples. Accordingly, the distinctive photoluminescence peaks at 743, 717, 698, 484, 465 and 442 nm in PL-2D (counter diagram and sections) and PL-3D (sequence spectra) ranging between 300 and 900 nm of wavelengths, and between 220 and 340 K of temperatures are observed. Finally, photoluminescence features of the heterogeneous-structured material cannot be simply attributed to any chemical impurities, since the jade mass has numerous heterogeneous mineral constituents instead of a single jadeite mineral. Six different mineral implications and chemical impurities in the material composition display complex and individual all kind of luminescence features. Therefore, photoluminescence as well as radioluminescence, cathodoluminescence and thermoluminescence spectra provide positive identification regarding to the provenance (geographic origin) of the original Turkish purple jade (turkiyenite). - Highlights: ► The purple-colored gem material is only found in the Harmancık-Bursa region of Turkey. ► Material is called “Turkish purple

Coal upgrading

2009-10-15

This report examines current technologies and those likely to be used to produce cleaner coal and coal products, principally for use in power generation and metallurgical applications. Consideration is also given to coal production in the leading coal producing countries, both with developed and developing industries. A range of technologies are considered. These include the coal-based liquid fuel called coal water mixture (CWM) that may compete with diesel, the production of ultra-clean coal (UCC) and coal liquefaction which competes with oil and its products. Technologies for upgrading coal are considered, especially for low rank coals (LRC), since these have the potential to fill the gap generated by the increasing demand for coal that cannot be met by higher quality coals. Potential advantages and downsides of coal upgrading are outlined. Taking into account the environmental benefits of reduced pollution achieved through cleaner coal and reduced transport costs, as well as other positive aspects such as a predictable product leading to better boiler design, the advantages appear to be significant. The drying of low rank coals improves the energy productively released during combustion and may also be used as an adjunct or as part of other coal processing procedures. Coal washing technologies vary in different countries and the implications of this are outlined. Dry separation technologies, such as dry jigging and electrostatic separation, are also described. The demonstration of new technologies is key to their further development and demonstrations of various clean coal technologies are considered. A number of approaches to briquetting and pelletising are available and their use varies from country to country. Finally, developments in upgrading low rank coals are described in the leading coal producing countries. This is an area that is developing rapidly and in which there are significant corporate and state players. 81 refs., 32 figs., 3 tabs.

Full Text Available In the complex environment of intensive care units, needs of patients’ relatives might be seen as the lowest priority. On the other hand, because of their patients’ critical and often uncertain conditions, stress levels of relatives are quite high. This study aims to adapt the Critical Care Family Need Inventory, which assesses the needs of patients’ relatives, for use with the Turkish-speaking population and to assess psychometric properties of the resulting inventory. The study was conducted in a state hospital with the participation of 191 critical care patient relatives. Content validity was assessed by expert opinions, and construct validity was examined by exploratory factor analysis (EFA. Cronbach’s alpha coefficient was used to determine internal consistency. The translated inventory has a content validity ratio higher than the minimum acceptable level. Its construct validity was established by the EFA. Cronbach’s alpha coefficient for the entire scale was 0.93 and higher than 0.80 for subscales, thus demonstrating the translated version’s reliability. The Turkish adaptation appropriately reflects all dimensions of needs in the original CCFNI, and its psychometric properties were acceptable. The revised tool could be useful for helping critical care healthcare workers provide services in a holistic approach and for policymakers to improve quality of service.

Bio-coal briquettes using low-grade coal

Science.gov (United States)

Estiaty, L. M.; Fatimah, D.; Widodo

2018-02-01

The technology in using briquettes for fuel has been widely used in many countries for both domestic and industrial purposes. Common types of briquette used are coal, peat, charcoal, and biomass. Several researches have been carried out in regards to the production and the use of briquettes. Recently, researches show that mixing coal and biomass will result in an environmentally friendly briquette with better combustion and physical characteristics. This type of briquette is known as bio-coal briquettes. Bio-coal briquettes are made from agriculture waste and coal, which are readily available, cheap and affordable. Researchers make these bio-coal briquettes with different aims and objectives, depending on the issues to address, e.g. utilizing agricultural waste as an alternative energy to replace fossil fuels that are depleting its reserves, adding coal to biomass in order to add calorific value to bio-coal briquette, and adding biomass to coal to improve its chemical and physical properties. In our research, biocoal briquettes are made to utilize low grade coal. The biomass we use, however, is different from the ones used in past researches because it has undergone fermentation. The benefits of using such biomass are 1. Fermentation turns the hemi cellulose into a simpler form, so that the burning activation energy decreases while the calorific value increases. 2. Enzym produced will bind to heavy metals from coal as co-factors, forming metals that are environmentally friendly.

Coal world production represents 3.5 billions of tons, plus 900 millions of tons of lignite. 50% of coal is used for power generation, 16% by steel making industry, 5% by cement plants, and 29% for space heating and by other industries like carbo-chemistry. Coal reserves are enormous, about 1000 billions of tons (i.e. 250 years of consumption with the present day rate) but their exploitation will be in competition with less costly and less polluting energy sources. This documents treats of all aspects of coal: origin, composition, calorific value, classification, resources, reserves, production, international trade, sectoral consumption, cost, retail price, safety aspects of coal mining, environmental impacts (solid and gaseous effluents), different technologies of coal-fired power plants and their relative efficiency, alternative solutions for the recovery of coal energy (fuel cells, liquefaction).

2010-01-01

CoalVal is a menu-driven Windows program that produces cost-of-mining analyses of mine-modeled coal resources. Geological modeling of the coal beds and some degree of mine planning, from basic prefeasibility to advanced, must already have been performed before this program can be used. United States Geological Survey mine planning is done from a very basic, prefeasibility standpoint, but the accuracy of CoalVal's output is a reflection of the accuracy of the data entered, both for mine costs and mine planning. The mining cost analysis is done by using mine cost models designed for the commonly employed, surface and underground mining methods utilized in the United States. CoalVal requires a Microsoft Windows? 98 or Windows? XP operating system and a minimum of 1 gigabyte of random access memory to perform operations. It will not operate on Microsoft Vista?, Windows? 7, or Macintosh? operating systems. The program will summarize the evaluation of an unlimited number of coal seams, haulage zones, tax entities, or other area delineations for a given coal property, coalfield, or basin. When the reader opens the CoalVal publication from the USGS website, options are provided to download the CoalVal publication manual and the CoalVal Program. The CoalVal report is divided into five specific areas relevant to the development and use of the CoalVal program: 1. Introduction to CoalVal Assumptions and Concepts. 2. Mine Model Assumption Details (appendix A). 3. CoalVal Project Tutorial (appendix B). 4. Program Description (appendix C). 5. Mine Model and Discounted Cash Flow Formulas (appendix D). The tutorial explains how to enter coal resource and quality data by mining method; program default values for production, operating, and cost variables; and ones own operating and cost variables into the program. Generated summary reports list the volume of resource in short tons available for mining, recoverable short tons by mining method; the seam or property being mined

Main characteristics of the radioactive enrichment in ashes produced in coal-fired power stations

2008-01-01

Under contract with the Spain's 'Nuclear Safety Council', a study is being conducted of the nation's largest nominal output coal-fired power stations. Its purpose is to assess the radiological impact on workers and local populations due to this source of NORM activity. One of the aspects of particular interest is the study of the radioactive enrichment in the combustion wastes relative to the different coals used as fuel (usually local bituminous coal or lignite, or imported coal). These wastes consist of fly ash (mostly fine particles collected in electrostatic precipitators), and bottom ash (larger in size, and collected wet or dry in hoppers below the boilers). In general terms, the enrichment factors measured were between 2 and 18 for the radionuclides 40 K, 226 Ra, 232 Th, and 210 Po. The magnitude of this enrichment factor depended mainly on the ash content of each coal, and hence on the type of coal used as fuel and the specific operation cycle in the different power stations. For the radionuclides 40 K, 226 Ra, and 232 Th, the enrichment was relatively similar in value in the fly and bottom ashes produced by the different types of coal used in the power stations studied. For 210 Po, however, as was expected, the enrichment was much greater in the fly ash than in the bottom ash for each coal analyzed. (author)

Coking coal outlook from a coal producer's perspective

Thrasher, E.

2008-01-01

Australian mine production is recovering from massive flooding while Canadian coal shipments are limited by mine and rail capacity. Polish, Czech, and Russian coking coal shipments have been reduced and United States coking coal shipments are reaching their maximum capacity. On the demand side, the Chinese government has increased export taxes on metallurgical coal, coking coal, and thermal coal. Customers seem to be purchasing in waves and steel prices are declining. This presentation addressed the global outlook for coal as well as the challenges ahead in terms of supply and demand. Supply challenges include regulatory uncertainty; environmental permitting; labor; and geology of remaining reserves. Demand challenges include global economic uncertainty; foreign exchange values; the effect of customers making direct investments in mining operations; and freight rates. Consolidation of the coal industry continued and several examples were provided. The presentation also discussed other topics such as coking coal production issues; delayed mining permits and environmental issues; coking coal contract negotiations; and stock values of coking coal producers in the United States. It was concluded that consolidation will continue throughout the natural resource sector. tabs., figs

Coal mine safety achievements in the USA and the contribution of NIOSH research

Energy Technology Data Exchange (ETDEWEB)

Esterhuizen, G.S.; Gurtunca, R.G. [NIOSH, Washington, DC (United States)

2006-12-15

Over the past century coal miner safety and health have seen tremendous improvements: the fatality and injury rates continue to decrease while productivity continues to increase. Many of the hazards that plagued miners in the past, such as coal bumps, methane and coal dust explosions, ground fall accidents and health issues have been significantly reduced. The contribution of NIOSH research includes products for prevention and survival of mine fires, methane control measures, design procedure for underground coal mines, methods for excavation surface controls, methods and procedures for blasting, laser usage in underground mines and prevention of electrocution from overhead power lines that have reduced accidents and injuries in underground coal mines. Health research has produced products such as the personal dust monitor, noise abating technologies and ergonomic solutions for equipment operators. Research priorities at NIOSH are set by considering surveillance statistics, stakeholder inputs and loss control principles. Future research in coal mining is directed towards respiratory diseases, noise-induced hearing loss, repetitive musculoskeletal injuries, traumatic injuries, falls of ground and mine disasters. The recent spate of accidents in coal mines resulted in the Miner Act of 2006, which includes a specific role for NIOSH in future mine safety research and development. The mine safety achievements in the USA reflect the commitment of industry, labour, government and research organizations to improving the safety of the mine worker.

1990-01-01

The weak coal market of the 1980's has enabled utilities and other users of coal to enjoy stable or falling prices for coal supplies. Falling prices for coal stimulated the renegotiation of numerous coal contracts in recent years, as buyers look to take advantage of lower fuel prices available in the marketplace. This paper examines the use of coal resale transactions as a means of reducing fuel costs, and analyzes the benefits and risks associated with such transactions

Dölarslan, Emre Sahin

2009-01-01

This paper reviews the effects of six post-modern management concepts as applied to Turkish forestry. Up to now, Turkish forestry has been constrained, both in terms of its operations and internal organization, by a highly bureaucratic system. The application of new thinking in forestry management, however, has recently resulted in new organizational and production concepts that promise to address problems specific to this Turkish industry and bring about positive changes. This paper will elucidate these specific issues and demonstrate how post-modern management thinking is influencing the administration and operational capacity of Turkish forestry within its current structure.

Full Text Available This article is the report of an investigation of pronunciation difficulties of Turkish speakers/learners of English which are due to differences in the sound-letter representations in the orthographies of the two languages, namely called “ortographic interference”. These difficulties are different in nature than those arising from differences in the sound sysytems of Turkish and English.1While Turkish orthography is to a large extent phonemic, i.e. employing a one-to-one letter-sound correspondence (with few exceptions such as k - kâr- ɡ - yegane- gavur, etc., English orthography, on the other hand, represents 46 sounds of the spoken language with 102 single or group of letters in the written language.Such actual difficulties arising from the differences in the orthographic sound-letter represenatations of Turkish and English are classified, evaluated, and their sources are explained through a detailed phonetic analysis as applied to research methods of “contarstive analysis” and “error analysis”, which are effective approaches in the field of Applied Linguistics and Foreign Language Learning.For different categories of difficulties, corrective exercises are recommended for the teaching and learning of English pronunciation to Turkish students.

IS THE J-CURVE EFFECT OBSERVABLE IN TURKISH AGRICULTURAL SECTOR?

Full Text Available This paper investigates whether or not the J-curve hypothesis holds in Turkish agricultural sector. The analysis is conducted using the model the most commonly employed in j-curve literature. Based on the data covering the period from 1986: I to 1998: III, our results indicate that, following devaluation, agricultural trade balance initially improves, then worsens, and then improves again. This pattern shows that J-curve effect does not exist in Turkish agricultural sector. Another important fi nding is that devaluation worsens the trade balance of the sector in the long run, a result contradicting with the earlier fi ndings for the Turkish economy as a whole.

Gender equality or patriarchal dividend: Structural change in Turkish nursing.

Science.gov (United States)

Herdman, Elizabeth; Badir, Aysel

2008-06-01

Turkey is attempting to join the European Union and is facing pressure to eliminate many forms of discrimination, including discrimination based on gender. In keeping with these aims, in early 2007 the Turkish government changed the law to permit Turkish men to become nurses. Given that Turkey is a highly patriarchal society and that occupational segregation by sex is a persistent feature, it is important to examine the potential outcome of the legislative changes. The aim of this paper is to explore the paradoxical potential for Turkish female nurses to experience increased discrimination in a system that is restructured by legislation to be non-discriminatory.

The first Brazilian historical mortality cohort study on miners was conducted. The cohort consisted of 3224 workers in the underground coal mining industry in southern Brazil. This industry has been operating since 1942 without compliance with any regulatory standards, since there were no relevant national regulations. Over almost 60 years, about 5000 workers were exposed to high levels of radiation. However, later radiation exposure was significantly reduced, particularly that due to radon exposure. Recent radon concentration measurements indicated an average annual exposure to radon progeny of 2.1 WLM, ranging from 0.2 to 7.2 WLM. As radon exposure in the past was unknown, it can be suggested that mine workers have not been working safely as regards the health hazard related to radon and radon progeny exposure. The cohort inclusion criteria are as follows: (a) all male employees who had worked for at least one year at the coal mine; (b) workers with complete workplace information (underground and surface); (c) employment hiring between 1945 and 1997 and (d) the worker must have been alive on 1 January 1979. Through multiple strategies of search it was possible to follow up the members of the cohort with a success rate of 92%. This paper presents the characteristics of the study population and provides information about the feasibility of conducting a retrospective mortality study in Brazil, taking into account the methodological and logistical difficulties of conducting such a study in a developing country.

Full Text Available In article the ideology of turkish foreign policy is analyzed, elaborated and successfully put into practice by the former Minister for Foreign Affairs, and nowadays by prime minister Ahmet Davutoglu. Foreign policy strategy of Davutoglu represents set of the interconnected theoretical (the flexible approach; consistency and systematic approach; new diplomatic style and practical principles directed on increase of a role of the Turkish state on international scene - balance between democracy and safety; “zero of problems with neighbours”; preventive and priority peace diplomacy; multidimensional foreign policy; rhythmical diplomacy. Each of principles possesses certain properties and characteristics which have always been presented as a certain purpose which is necessary for reaching Turkey in the difficult international environment. Undoubtedly, A. Davutoglu's ideology has brought the huge contribution to activization and expansion of foreign policy of Turkey last decade. The merit of Davutoglu consists that it has cardinally changed the approach of the Turkish state to the foreign policy which was based earlier on such postulate - “the best friend of a Turk is a Turk”. However the destructive events which have passed and occurring today as in the Turkish state (terrorism strengthening, instability of political system, and also in region of the Middle East - civil war in Syria, deterioration of relations with Russia, Greece, Syria, Iran and Iraq have called into question a number of positions of the concept of Davutoglu in this connection in article some attention to the critic of its approach is paid also.

Full Text Available Relevance and purpose of the study. Under modern conditions, the share of loss-making enterprises of the coal industry is still high. This brings the solution of the problem of improving the efficiency of their activities up to date. It also determines the purpose of this research. Research methods: scientific generalization, system and factor analysis, and statistical modeling are used in the present work. Results. The article discusses the economic and theoretical aspects of planning the effective activities in the coal industry. The paper analyzes the elasticity of the unit cost price in terms of its labor productivity. It also deals with the elasticity of the volume of output in terms of labor productivity. This indicates that the existing coal mining technologies have, to some extent, exhausted their advantages in the coal industry. They require a change on the achieved level of the capital-labor ratio. It is recommended to strive to ensure advanced ratio of growth of labor productivity of workers compared to the growth rate of unit costs. This should be done at the introduction of a new technology at the enterprises of the coal industry. The advanced ratio of growth in output compared to the growth rate of labor productivity of workers should also be guaranteed. The early growth rate of revenue from sales compared to the growth rate in total costs of production should be provided. The advanced ratio of profit growth compared to the growth rate of revenue from sales has to be provided as well. It is proven that for coal industry enterprises the type of competitive advantages called “the lowest costs” can be the only acceptable one in comparison with other types. We have considered the requirements to the new developed technologies for coal mining. They are as follows: the value of marginal profit in the planned period should be more than the fixed costs of the enterprise; the value of marginal profit in the planned period should be more

2017-01-01

Full Text Available The current study explored the psychometric properties of the newly designed Turkish version of the Cognitive Test Anxiety Scale–Revised (CTAR. Results of an exploratory factor analysis revealed an unidimensional structure consistent with the conceptualized nature of cognitive test anxiety and previous examinations of the English version of the CTAR. Examination of the factor loadings revealed two items that were weakly related to the test anxiety construct and as such were prime candidates for removal. Confirmatory factor analyses were conducted to compare model fit for the 25- and 23-item version of the measure. Results indicated that the 23-item version of the measure provided a better fit to the data which support the removal of the problematic items in the Turkish version of the CTAR. Additional analyses demonstrated the internal consistency, test–retest reliability, concurrent validity, and gender equivalence for responses offered on the Turkish version of the measure. Results of the analysis revealed a 23-item Turkish version of the T-CTAR is a valid and reliable measure of cognitive test anxiety for use among Turkish students.

Increasing evidence suggest that occupational exposure to open-cast coal mining residues like dust particles, heavy metals and Polycyclic Aromatic Hydrocarbons (PAHs) may cause a wide range of DNA damage and genomic instability that could be associated to initial steps in cancer development and other work-related diseases. The aim of our study was to evaluate if key polymorphisms in metabolism genes CYP1A1Msp1, GSTM1Null, GSTT1Null and DNA repair genes XRCC1Arg194Trp and hOGG1Ser326Cys could modify individual susceptibility to adverse coal exposure effects, considering the DNA damage (Comet assay) and micronucleus formation in lymphocytes (CBMN) and buccal mucosa cells (BMNCyt) as endpoints for genotoxicity. The study population is comprised of 200 healthy male subjects, 100 open-cast coal-mining workers from "El Cerrejón" (world's largest open-cast coal mine located in Guajira - Colombia) and 100 non-exposed referents from general population. The data revealed a significant increase of CBMN frequency in peripheral lymphocytes of occupationally exposed workers carrying the wild-type variant of GSTT1 (+) gene. Exposed subjects carrying GSTT1null polymorphism showed a lower micronucleus frequency compared with their positive counterparts (FR: 0.83; P=0.04), while BMNCyt, frequency and Comet assay parameters in lymphocytes: Damage Index (DI) and percentage of DNA in the tail (Tail % DNA) were significantly higher in exposed workers with the GSTM1Null polymorphism. Other exfoliated buccal mucosa abnormalities related to cell death (Karyorrhexis and Karyolysis) were increased in GSTT/M1Null carriers. Nuclear buds were significantly higher in workers carrying the CYP1A1Msp1 (m1/m2, m2/m2) allele. Moreover, BMNCyt frequency and Comet assay parameters were significantly lower in exposed carriers of XRCC1Arg194Trp (Arg/Trp, Trp/Trp) and hOGG1Ser326Cys (Ser/Cys, Cys/Cys), thereby providing new data to the increasing evidence about the protective role of these polymorphisms

The aim of this study was to investigate the relationships between the stages of calcification of teeth and the cervical vertebral maturity stages in Turkish subjects. A retrospective cross-sectional study was designed. The final study population consisted of 590 Turkish subjects. Statistical analysis of the data was performed with computer software. Spearman rank order correlation coefficients were used to assess the relationship between cervical vertebral and dental maturation. For a better understanding of the relationship between cervical vertebral maturation indexes and dental age, percentage distributions of the studied teeth were also calculated. Strict correlations were found between dental and cervical vertebral maturation of Turkish subjects. For males, the sequence from lowest to the highest was third molar, central incisor, canine, first premolar, second premolar, first molar, and second molar. For females, the sequence from lowest to the highest was third molar, canine, second premolar, first premolar, central incisor, first molar, and second molar. Dental maturation stages can be used as a reliable indicator of facial growth.

Full Text Available Liquid hydrocarbons from the coal bed and surrounding rocks, besides the stored gases, methane, carbon dioxide, carbon oxide, generate the increase of the risk factor from the occupational health and safety point of view. If for reducing the gas concentrations level and the methane emissions in order to increase the safety in exploitation exist well-known solutions and methods, the oxidation or self-oxidation of the hydrocarbons from the coal bed generate a series of compounds, reaction products over maximum admitted concentrations which give birth to a toxic atmosphere and which is hazardous for workers, at the same time inducing an error in noting the occurrence of a spontaneous combustion phenomena, a major risk for the workers and for the mineral resource. This paper represents a case study performed in one underground mine unit from Jiu Valley and presents the analysis for underground environment factors monitoring and for solutions for diminishing the OHS risk factors.

Knowledge about culture- and migration-specific characteristics of subjective illness beliefs in Turkish patients is necessary for adequate treatment. Analysis of subjective illness beliefs in Turkish patients (F3; F4; n = 79) in comparison to matched Germans (n = 79) using a modified version of the Illness Perception Questionnaire IPQ-R. Differences were explored by t-tests and chi(2)-tests. Turkish patients believed significantly stronger in a chronical timeline of illness and in negative illness consequences, while German patients believed significantly stronger in treatment control and personal control. Turkish patients more often mentioned external causes of their disease compared to Germans. The results provide explanations of the deficient health care situation for Turkish migrants in Germany.

Swedish consumption of coal and coke during 1991 and trends in technology, environment and market aspects of coal use are reported. Steam coal use in the heating sector was unchanged from 1991, 1.2 Mtons. Reduced consumption in smaller district heating units (due to conversion to biofuels and gas) was compensated by increased use for power generation in cogeneration plants. Coal consumption in industry fell 0.10 Mton to 0.84 Mton due to lower production in one industry branch. Import of steam coal was 1.1 Mton (down 0.5 Mton from 1990) since new rules for strategic reserves allowed a reduction of stocks. During the last five years stocks have been reduced by 2 Mtons. Import of metallurgical coal was 1.6 Mton, unchanged from 1990. The report also gives statistics for the coal using plants in Sweden, on coal R and D, and on emission laws for coal firing.

Zejda, J. E.; Stasiow, B.

2003-01-01

A series of 685 x-rays films of the cervical spine obtained in coal miners was analyzed to explore the occurrence of narrowed disc spaces and osteophytes in this occupational group, and to examine the association of x-rays changes with age, duration of employment, and duration of occupational exposure to hand-arm vibration. All data were extracted from individual medical files of coal miners examined for suspected hand-arm vibration-related disorders in 1989-1999 at the Occupational Medicine Center in Katowice. The narrowed intervertebral disc spaces were found in 188 coal miners (26.9%) and osteophytes in 332 coal miners (47.5%). The occurrence of degenerative changes in coal miners was similar to that observed in a small group of 68 blue-collar workers (no exposure to hand-arm vibration) employed in the coal industry. Univariate comparisons showed that intervertebral disc spaces and osteophytes were more frequent among older subjects and among subjects with longer duration of employment. The results of logistic regression analysis confirmed statistically significant effect of age, but not of other factors included in the model. When both x-ray changes were grouped together (a combined dependent variable) age remained the only statistically significant explanatory variable. The findings do not support the view that the examined degenerative changes in cervical spine are more prevalent in coal miners and depend on duration of physical work or local exposure to hand-arm vibration in this occupational group.

A newer concept of setting up coal refineries in coal utilising industries through environmentally sound clean coal technology of organosuper refining of coals

International Nuclear Information System (INIS)

Sharma, D.K.

1994-01-01

In order to reduce the losses of premium organic matter of coal and its immense potential energy which is present in the form of stronger interatomic and intramolecular bonding energies, a newer and convenient technique of recovering the premium organic matter from low grade coals by organosuper-refining technique which operates under ambient pressure conditions has been developed. The residual coal obtained can be used as environmentally clean fuel or as a feedstock for the industries based on carbonization and gasification. It is suggested that a beginning be made by setting up coal refineries in coal utilizing industries on the basis of the presently developed new technology of organosuper-refining of coals to recover premium grade organic chemical feed stocks from coals before utilizing coal by techniques such as bubble bed or recirculatory fluidized bed or pulverized coal combustion in thermal power stations, carbonization in steel plants or other carbonization units, gasification in fertilizer industries or in integrated coal gasification combined cycle power generation. Thus, coal refineries may produce value added aromatic chemical feed stocks, formed coke or coke manufacturing; and carbon fillers for polymers. (author). 100 refs., 1 fig

An example of change - the end of apartheid in the South African coal industry

Energy Technology Data Exchange (ETDEWEB)

1989-01-01

This publication reports on a visit by four British MPs to the South African Coal Industry (SACI), made under the auspices of the SACI Committee which represents all the major coal exporting companies of South Africa. It is a private industry which operates independently of both the Government and the Chamber of Mines and does not benefit from any Government Subsidies. The aim of the visit was to investigate the SACI against a background of international pressure against an industry which appears to be a major example of change in South Africa. The visit programme included presentations on the South African coal industry in general, industrial relations and safety and research in the mining industry. Visits were made to both an underground mine and an opencast mine, a collieries training college, hospital, school, mine village and a coal terminal. At the end of the visit the delegation drew the conclusions that the South African coal industry is now organised on a totally non-discriminatory basis, offering employment and promotion opportunities to all workers regardless of their race and that there is therefore no justification for singling out this industry as a victim of sanctions policy.

Description of the operation and radiological impact of a spanish coastal coal-fired power station

International Nuclear Information System (INIS)

Corbacho, Jose A.; Baeza, Antonio; Robles, Beatriz; Mora, Juan C.; Cancio, David

2008-01-01

The 'Litoral' Coal-Fired Power Plant (LCFPP) is situated in the town of Carboneras (Almeria) in southern Spain. Its nominal output power is 1589 M We. The fuel used is imported sub-bituminous coal supplied by collier vessels, and unloaded in a port annexed to the plant. The climate of the area is semi-arid mediterranean, with particularly low rainfall. The plant's radiological impact was studied considering various exposure pathways for the workers and the general public. In particular, inhalation and external exposure contributions to the effective dose due to the different materials involved in the operation (coals, fly ash, and bottom ash) were evaluated. Alpha spectrometry was used to characterize radiologically the airborne particulates collected in aerosol filters at points within the installation, and to determine 210 Po levels in aerosols collected in filters placed around the power station. High resolution gamma spectrometry was used to characterize coal and ash samples from the plant, and soil samples collected outside the installation within a radius of 5 km. A dose rate monitor was used to measure the ambient dose equivalent at different points inside and outside the plant. Samples of the seawater used in the plant and of products for human consumption produced nearby were also collected and characterized radiologically. The effective dose was evaluated following a realistic approach based principally on experimental measurements and in situ observations, complemented with mathematical models when necessary. The resulting estimated effective doses for selected representative groups of workers and general public were all below the reference levels used in this work. (author)

Predicted coal production trends in Kentucky: The results of available coal resources, coal quality demands, and regulatory factors

International Nuclear Information System (INIS)

Watson, W.D.

1993-01-01

Many factors affect the viability of regional coal production markets including (1) coal quality and recoverable tonnage, (2) coal mining cost, (3) the regional and time varying patterns of coal demand growth, (4) regulations and other institutional constraints that affect coal demand and utilization, and (5) the regional array of coal transport modes and rates. This analysis integrates these factors into an assessment of coal production prospects (separately) for eastern and western Kentucky coal producing counties for the decade of the 90's. The integration indicates that eastern Kentucky coal production will peak and begin to decline by the end of the decade whereas western Kentucky coal production will continue to grow. No single factor explains these trends. There is plenty of available minable coal. The combination of changes in environmental regulations, some increase in coal mining costs, and the mining-out of low sulfur reserves are the main factors that account for the production trends

Depressive disorder among Turkish women in the Netherlands: a qualitative study of idioms of distress.

Science.gov (United States)

Borra, Ria

2011-11-01

The provision of mental health services to immigrants in the Netherlands is hampered by difficulty in establishing valid diagnoses of psychiatric disorders. To improve the process of diagnosing depressive disorder among Turkish women in Dutch mental healthcare, we conducted a qualitative study of women with depression in Rotterdam. A bilingual Turkish-Dutch diagnostic interview was developed to explore Turkish women's idioms of distress. Interviews were conducted with 20 women with a disputed diagnosis of depression. Results showed that distress among the Turkish women was characterized by a wide range of somatic complaints, with anxiety and agitation occurring as frequently as depressive complaints. Because the range of complaints is so varied, major depression may be underdiagnosed in the Turkish immigrant population.

The process of identifying and documenting the quality parameters of coal, as well as the conditions of coal deposition in the seam, is multi-stage and extremely expensive. The taking and analyzing of seam samples is the method of assessment of the quality and quantity parameters of coals in deep mines. Depending on the method of sampling, it offers quite precise assessment of the quality parameters of potential commercial coals. The main kind of seam samples under consideration are so-called "documentary seam samples", which exclude dirt bands and other seam contaminants. Mercury content in coal matter from the currently accessible and exploited coal seams of the Upper Silesian Coal Basin (USCB) was assessed. It was noted that the mercury content in coal seams decreases with the age of the seam and, to a lesser extent, seam deposition depth. Maps of the variation of mercury content in selected lithostratigraphic units (layers) of the Upper Silesian Coal Basin have been created.

Full Text Available The present studies aim to compare the cultural values promoted by the French educational system and the Turkish families living in France to their youngsters. Because of their collectivist background Turkish immigrants may convey less individualistic values to their children compared to French parents and teachers. However, Turkish students may become more individualistic as they are socialized in the school system. In study 1 (N = 119, French school teachers, French parents, and Turkish-origin parents had to resolve six dilemmas by choosing either an individualistic or a collectivistic response-option. As expected, French teachers emphasized individualism more than Turkish parents, but not more than French parents. In Study 2 (N = 159, similar dilemmas were presented to French and Turkish-origin pupils. In elementary school, Turkish children were less individualistic than French-born children, but this gap was reduced in high school.

2018-02-01

Referring to the national energy policy targets for the years 2025, the government has launched the use of coal briquettes as an alternative energy replacement for kerosene and firewood. Non-carbonized briquettes in the form of coal briquettes as well as bio-coal briquettes are used in many small-medium industries and households, and are rarely used by large industries. The standard quality of coal briquettes used as raw material for non-carbonized briquettes is a minimum calorific value of 4,400 kcal/kg (adb); total sulfur at a maximum of 1% (adb), and water content at plants), the environment of deposition, and the geological conditions of the surrounding area, so that the coal deposits in each region will be different as well as the amount and also the quality. Therefore, the quantity and the quality of coal in each area are different to be eligible in the making of briquettes to do blending. In addition to the coal blending, it is also necessary to select the right materials in the making of coal briquettes and bio-coal briquettes. The formulation of the right mixture of material in the making of briquettes, can be produced of good quality and environmental friendly.

Plans are under way to mine the Beluga coal fields on the west side of Cook Inlet. The coal will be strip-mined for export, or to supply local electric generating plants, or both. Over the next 20 years, this coal development activity is likely to generate social and economic impacts at the local, regional, and state levels. The purpose of this study is to assess the potential social and economic effects of coal development, including employment and population growth, regional impacts, and the facility and service needs of a new settlement in the Beluga area. Of special concern is identifying the role of various governmental agencies in the development process. Potential effects on the natural environment are not examined in detail since they are expected to be controlled to acceptable levels through existing Federal and state laws. This report examines three possible levels of coal-field development and the settlement requirements associated with each. The most probable regional impacts associated with this development will include effects on the regional labor force, the market for coal, and the generation and distribution of revenues. The main regional labor force impacts will be positive in nature. The rate of regional unemployment is likely to decline slightly for the duration of the project, with an increase in wage income available for reinvestment in the region and a reduction in the number of individuals receiving unemployment insurance payments. Coal development is not expected to induce any significant inmigration of workers from outside the region.The development of the Beluga coal resources and the production of electricity from coal would add to the Kenai Peninsula Borough's tax base. The assessed value of coal lands around Beluga would likely increase and, in addition, Cook Inlet Region, Inc. would be the recipient of royalties from coal leases. A number of recommendations for research and governmental activities are presented.

It is important to adapt utility boilers to sub-bituminous coals to take advantage of their environmental benefits while limiting operation risks. We discuss the performance impact that Adaro, an Indonesian sub-bituminous coal with high moisture content, has on opposite-wall and tangentially-fired utility boilers which were designed for bituminous coals. Numerical simulations were made with GLACIER, a computational-fluid-dynamic code, to depict combustion behavior. The predictions were verified with full-scale test results. For analysis of the operational parameters for firing Adaro coal in both boilers, we used EXPERT system, an on-line supervision system developed by Israel Electric Corporation. It was concluded that firing Adaro coal, compared to a typical bituminous coal, lowers NOx and SO{sub 2} emissions, lowers LOI content and improves fouling behavior but can cause load limitation which impacts flexible operation. 21 refs., 7 figs., 3 tabs.

Petrographic And Geochemical Relationships And Environmentally Significant Trace Element Contents Of Miocene Coals in The Çayirli (Erzincan) Area, Eastern Anatolia, Turkey

This study has done related to the petrographic, coal-quality and the environmental influences of the Çayırlı coal field in the Eastern Anatolia. The region is one of the best examples of a continental collision zone in the world and located in a North-south converging collision zone between the Eurasian and the Arabian Plates. The geological units on the North of the basin are the peridotites and on the South, the Upper Triassic to Lower Cretaceous limestone. Tertiary sedimentary units also occupy a significant part of the geological features. Lower Miocene sediments include recifal limestone, marls, green clay and coal seams. The Çayırlı mining area in Eastern Anatolia region, contains these Miocene aged coals. These coals is characterized by high vitrinite and inertinite and low liptinite contents. The coals are Bituminous coal rank, with vitrinite reflectance ranging from 0.53 to 0.58%. Chemically, the coal in this study is characterised by low moisture, ash yield and sulfur content. The Çayırlı coal consist mainly of SiO2 and CaO, with secondary Fe2O3, Al2O3, and minor proportions of TiO2, P2O5 and other oxides. Several trace elements of environmental concern namely As, U and Be in Çayırlı coal are above the world averages, while Ni and Pb concentrations are less than the world average. However, As, Co, Cr, Ni, Pb, U and V contents of this coal are below Turkish averages. It can clearly observed that the concentration of the elements is highest in the high ash coal levels. Among the potentially hazardous trace elements, Be, Co, Ni, Se and U may be of little or no health and environmental concerns, wheras As, Pb, Sb, and Th require further examination for their potential health and environmental concerns. These properties may be related to evaluation of the coal forming environment from more reducing contitions in a marine influenced lower delta plain environment for investigated coals. On the basis of analytical data, there is no possibility that

1997-01-01

Contents, concentration trends, and modes of occurrence of 67 elements in coals, coal ashes, and combustion wastes at eleven Bulgarian thermoelectric power stations (TPS) were studied. A number of trace elements in coal and coal ash have concentrations greater than their respective worldwide average contents (Clarke values). Trace elements are concentrated mainly in the heavy accessory minerals and organic matter in coal. In decreasing order of significance, the trace elements in coal may occur as: element-organic compounds; impurities in the mineral matter; major components in the mineral matter; major and impurity components in the inorganic amorphous matter; and elements in the fluid constituent. A number of trace elements in the waste products, similar to coal ashes, exceed known Clarke contents. Trace elements are mainly enriched in non-magnetic, heavy and fine-grained fractions of fly ash. They are commonly present as impurities in the glass phases, and are included in the crystalline components. Their accessory crystalline phases, element-organic compounds, liquid and gas forms, are of subordinate importance. Some elements from the chalcophile, lithophile and siderophile groups may release into the atmosphere during coal burning. For others, the combustion process appears to be a powerful factor causing their relative enrichment in the fly ash and rarely in the bottom ash and slag. 65 refs., 1 fig., 11 tabs

2018-04-01

Full Text Available Rapid developments and increasing competition in recent years have prevented companies from producing and selling only in domestic markets, but also causing their foreign resources and investments to be directed to foreign markets. In this case, once businesses decide to join a particular market, they have to decide which is the best way to penetrate there. Turkish multinational corporations, which have been spreading all over the world with their investments, have conquered world markets with their exports, initiatives and acquisitions, they have entered in foreign markets in various forms and have a significant share in world trade volume with their successful investments. From this point of view, this study examines the strategies by which Turkish multinationals enter foreign markets especially in Kosovo and the impact that those companies have had in the development of the Kosovo economy and the strategies by which Turkish multinationals enter foreign markets.

Jenner, Steffen; Lamadrid, Alberto J.

2013-01-01

The aim of this paper is to examine the major environmental impacts of shale gas, conventional gas and coal on air, water, and land in the United States. These factors decisively affect the quality of life (public health and safety) as well as local and global environmental protection. Comparing various lifecycle assessments, this paper will suggest that a shift from coal to shale gas would benefit public health, the safety of workers, local environmental protection, water consumption, and the land surface. Most likely, shale gas also comes with a smaller GHG footprint than coal. However, shale gas extraction can affect water safety. This paper also discusses related aspects that exemplify how shale gas can be more beneficial in the short and long term. First, there are technical solutions readily available to fix the most crucial problems of shale gas extraction, such as methane leakages and other geo-hazards. Second, shale gas is best equipped to smoothen the transition to an age of renewable energy. Finally, this paper will recommend hybrid policy regulations. - Highlights: ► We examine the impacts of (un)conventional gas and coal on air, water, and land. ► A shift from coal to shale gas would benefit public health. ► Shale gas extraction can affect water safety. ► We discuss technical solutions to fix the most crucial problems of shale gas extraction. ► We recommend hybrid regulations.

Financial Policies of Turkish Industrial Companies during the Global Crisis

2016-01-01

Full Text Available Latest global financial crisis that shrank the credit market affected the companies’ financial policies since the credit contraction led the firms to rely more on their own resources rather than external financing. The expectation during such crises is more equity issues along with less borrowing. In economic literature there are some evidence supporting this fact for developed countries. As an emerging country Turkey’s case is different than that of advanced countries. The era commenced with Lehman turmoil by passed Turkish economy in the first years due to the solid, strong and healthy banking sector due to the measurements taken after 2001 banking crisis of Turkey. Therefore, international lenders did not hesitate directing their funds to Turkish banks. As a result, Turkish companies did not suffer in financing their investments through bank loans. Moreover, the growth policy of Turkey based on current account deficit supported Turkish economy and in turn the firms due to the abundance of liquidity after the peak of the crisis. In this work we examined 164 industrial firms that are traded on Borsa Istanbul to see if there happened to be a shift in their financing preferences during the recent global crisis. We found that the importance of borrowing had not decreased and that contradicts the expectations. As of equity issues, before and after 2009 no radical change has been observed. In 2009 where the crisis hit worst Turkish economy leading a 4.7% GDP decrease, the equity issues were doubled.

Full Text Available The article covers a little-known story of non-canonic Orthodox jurisdiction called “Turkish Orthodox Church” that appeared in 1920s as a schismatic organisation with strongly pronounced Turkish nationalism and extreme intolerance to the canonic Constantinopolitan Orthodox Church. A historical link between the orthodox citizens of Turkey with Greece stirred up ill-feeling in pro-Turkish nationalists. That caused raft of attempts to capture church property from the canonic churches. Despite uproars and big words schismatic didn’t attract many orthodox and remained as uninteresting issue for Turkish politicians. Without any governmental support non-canonic “Turkish Orthodox Church” gradually turned into socio-political group of devoted nationalists that are mainly the relatives of priest Paul Karakissadiris, the founder of this religious organization. Today “Turkish Orthodox Church” being mostly a political project has liberal elements and denies canonic division of Orthodox Church of schismatic community.

Full Text Available The purpose of this study was to investigate the influence of intellectual capital of Turkish automotive supplier industry upon their innovation performance. This study showed that three types of intellectual capital – employee capital, structural capital, and customer capital – had a significantly positive relationship with innovation performance. Moreover, the results also indicated that the higher the growth rate of an industry, the stronger were the positive relationships between three types of intellectual capital and innovation performance. Besides, customer capital was the greatest among these three types of intellectual capital in Turkish automotive supplier industry, employee capital was the next, and structural capital was the least. This shows two points; first, Turkish automotive supplier industry emphasized the interactive “relations” with their suppliers, clients, and partners; second, it was imperative for Turkish manufacturing enterprises to develop their structural capital to increase their innovation performance.

There are a limited number of menopause-specific quality-of-life scales for the Turkish population. This study was conducted to evaluate the validity and reliability of the Turkish Utian Quality-of-Life Scale in postmenopausal women. The study group was comprised of 250 postmenopausal women who applied to a training and research hospital's menopause clinic in Turkey. A survey form and the Turkish Utian quality-of-Life Scale were used to collect data, and the Turkish version of Short Form-36 was used to evaluate reliability with an equivalent form. Language-validity, content-validity, and construct-validity methods were used to assess the validity of the scale, and Cronbach's α coefficient calculation and the equivalent-form reliability methods were used to assess the reliability of the scale. The Turkish Utian Quality-of-Life Scale was determined to be a valid and reliable instrument for measuring the quality of life of postmenopausal women. Confirmatory factor analysis demonstrates that the instrument fits well with 23 items and a four-factor model. The Cronbach's α coefficient for the quality-of-life domains were as follows: 0.88 overall, 0.79 health, 0.78 emotional, 0.76 sexual, and 0.75 occupational. Reliability of the instrument was confirmed through significant correlations between scores on the Turkish version of the Utian Quality-of-Life Scale and the Turkish version of the Short Form-36 (r = 0.745, P measuring quality of life during menopause.

Occupational injuries cause major health problems in all nations. Coal mining is one of the largest, oldest industries in the world. However, there is relatively little available literature concerning the health status of coal miners. The purpose of this work is to assess the prevalence of periodontal disease among coal miners and provide a basis for planning and evaluating the data from community oral health services. A cross-sectional study was conducted 106 men selected based on a stratified cluster sampling procedure. The study was performed among the mine workers of Zonguldak, Kozlu District, Turkey. The questionnaire prepared by the American Academy of Periodontology risk assessment test was used for the evaluation. The data were collected byWorld Health Organization (WHO) oral health assessment form, and clinical examination was conducted by the method recommended by the WHO oral health surveys. Statistical analysis was performed using SPSS software programme. The overall prevalence of periodontal disease was found to be 96.2% and was determined by considering subjects with Community Periodontal Index scores of 1-4 as diseased and the healthy subjects comprised of a mere 3.8%. Furthermore, various disturbing or embarrassing work conditions were reported. Statistically significant differences were observed among the workers who brush their teeth daily and visit dental attendance within the last two years have better periodontal status than those of the others (p < 0.05). The present level of periodontal disease in coal mine workers is severe. Moreover, its distribution and severity are strongly influenced by host susceptibility and risk factors. The priority should be based on population strategy and primary prevention programmes to benefit the periodontal health by promoting self-care and oral hygiene.

The aim of this study was to investigate the effect of the radiological evidence of emphysema, and the extent of interstitial involvement, on lung function and pulmonary arterial pressure (PAP) in patients with coal workers' pneumoconiosis (CWP). All patients showed a mild decrease in FEV1/FVC and a mild increase in FRC. Forty-four per cent of patients developed mild to moderate pulmonary hypertension. Emphysema scores correlated significantly with airflow rates, including FEV1%, FEV1/FVC and FEF25-75%, and with carbon monoxide diffusing capacity (DLCO)% predicted as well as FRC% predicted and the ratio RV/TLC, which are indices of air trapping. Additionally, profusion and global profusion scores showed significant correlation with FEV1/FVC, DLCO% predicted, specific airway conductance and smoking. Mean PAP showed a significant negative correlation with FEF50% predicted, DLCO% predicted and profusion score. The impairment of pulmonary function (mainly disturbance in airflow rates and air trapping) and pulmonary hypertension may be present, even in a simple form of CWP. The pulmonary function impairment in patients with CWP is likely to be attributable to the occurrence of emphysema. However, pulmonary hypertension was directly related to the profusion of pneumoconiotic nodules, which may result in obliteration of the vascular bed.

Full Text Available This study investigates the role of macroeconomic instability on potential growth rate of output in Turkey over the period 1960-2006. In doing so, it also attempts to estimate the potential growth rate of Turkish economy over the sample period by using Hodrick-Prescott filter and model based on production function approach. Descriptive and empirical results suggest that Turkish economy suffered from a significant output loss during the chronic instability episodes, between the mid-1970s and 2001. A significant fall in macroeconomic instability has provided the main contribution to the achievement of the recent high growth episode (2002-2006 of Turkish economy. However, in order to continue the desired high growth performance in near future it is necessary to accelerate both human and physical capital formation while preserving stability.

Full Text Available Nowadays, the acceleration of knowledge-based global competition and the knowledge economy that become the key to social development requires a transformation of the economic structure of the country to the knowledge economy. How successful is this transformation or how to proceed in the transformation process has a critical importance, especially for the developing countries. In this context, by analyzing the knowledge economy performances of the Turkish Republics, their proceedings in the process of becoming an knowledge economy are examined. For this purpose, analysis was carried out utilizing the knowledge, knowledge economy, and networked readiness index that formed from the elements of the knowledge economies. As a conclusion, these countries have to cover a distance in the context of knowledge economy transformation. In order to achieve this, these countries should establish; national innovation network by knowledge-innovation production together with institutional-legal regulations for innovative entrepreneurship, educational reforms to be able to create knowledge workers with human capital for produce, use and share the knowledge, and in order to do all these they should provide knowledge and communication infrastructure and ensure dissemination of it.

Taking it to the grave: gender, cultural capital, and ethnicity in Turkish death announcements.

Science.gov (United States)

Ergin, Murat

Popularly considered a great equalizer, death and the rituals around it nevertheless accentuate social distinctions. The present study focuses on a sample (N = 2554) of death announcements in a major Turkish daily newspaper (Hürriyet) from 1970 to 2006. Out of the liminal position of Turkish death announcements between obituaries and death notices emerges a large decentralized collection of private decisions responding to death, reflecting attitudes toward gender, ethnic/religious minority status and cultural capital, and echoing the aggregate efforts of privileged groups to maintain a particular self-image. Class closures lead to openings for traditionally under-represented minorities, such as Jewish Turkish citizens and citizens of Greek or Armenian origin. Results reveal that signs of status and power in announcements are largely monopolized by men of Turkish-Muslim origins. Although the changes in the genre-characteristics of death announcements are slow, they correspond to major turning points in Turkish social history.

Five energy companies in the Netherlands want to build additional coal-fired power plants: Essent and Nuon, the German company RWE and E.ON and the Belgian company Electrabel. Coal-fired power plants emit 70 percent more CO2 than gas-fired power plants. Especially because of the threat to the climate Greenpeace believes that no more coal-fired power plants should be built. In this publication Greenpeace explores the pollution, the working conditions and human rights with regard to the exploitation of coal. That has been elaborated for the three countries from which Dutch energy companies import coal: South Africa, Colombia and Indonesia. In addition to information about the origin of coal also insight is given into the coal market (stocks and use), the enormous coal transport and the world trade [nl

This study analyzed the methods used to teach the multiplication of fractions in Turkish and American textbooks. Two Turkish textbooks and two American textbooks, Everyday Mathematics (EM) and Connected Mathematics 3 (CM), were analyzed. The analyses focused on the content and the nature of the mathematical problems presented in the textbooks. The findings of the study showed that the American textbooks aimed at developing conceptual understanding first and then procedural fluency, whereas the Turkish textbooks aimed at developing both concurrently. The American textbooks provided more opportunities for different computational strategies. The solutions to most problems in all textbooks required a single computational step, a numerical answer, and procedural knowledge. Furthermore, compared with the Turkish textbooks, the American textbooks contained a greater number of problems that required high-level cognitive skills such as mathematical reasoning.

The Safety Attitudes of Senior Managers in the Chinese Coal Industry

2016-11-01

Full Text Available Introduction: Senior managers’ attitudes towards safety are very important regarding the safety practices in an organization. The study is to describe the current situation of senior managers′ attitudes towards safety in the Chinese coal industry. Method: We evaluated the changing trends as well as the reasons for these changes in the Chinese coal industry in 2009 and in 2014 with 168 senior manager samples from large Chinese state-owned coal enterprises. Evaluations of 15 safety concepts were performed by means of a questionnaire. Results and Conclusions: Results indicate that, in 2014, three concepts were at a very high level (mean > 4.5, and six were at a relatively high level (4.5 > mean > 4.0. Analyses of changing trends revealed that nine concepts improved significantly, while four greatly declined in 2014 compared to those in 2009. The data reported here suggest that the reasons for the significant improvement with respect to the nine concepts include the improvement in social and legal environments, the improvement of the culture of social safety, workers′ safety demands being met, and scientific and technical advances in the coal industry. The decline of the four concepts seemed to be caused by a poor awareness of managers in the coal industry that safety creates economic benefits, insufficient information on safety, inadequate attention to the development of a safety culture and safety management methods, and safety organizations and workers′ unions not playing their role effectively. Practical Applications: We therefore recommend strengthening the evidence that safety creates economic benefits, providing incentives for employees to encourage their participation in safety management, and paying more attention to the prevention of accidents in coal mines via safety organizations and unions. These results can provide guidelines for workers, industrialists, and government regarding occupational safety in the whole coal industry.

Introduction: Senior managers’ attitudes towards safety are very important regarding the safety practices in an organization. The study is to describe the current situation of senior managers′ attitudes towards safety in the Chinese coal industry. Method: We evaluated the changing trends as well as the reasons for these changes in the Chinese coal industry in 2009 and in 2014 with 168 senior manager samples from large Chinese state-owned coal enterprises. Evaluations of 15 safety concepts were performed by means of a questionnaire. Results and Conclusions: Results indicate that, in 2014, three concepts were at a very high level (mean > 4.5), and six were at a relatively high level (4.5 > mean > 4.0). Analyses of changing trends revealed that nine concepts improved significantly, while four greatly declined in 2014 compared to those in 2009. The data reported here suggest that the reasons for the significant improvement with respect to the nine concepts include the improvement in social and legal environments, the improvement of the culture of social safety, workers′ safety demands being met, and scientific and technical advances in the coal industry. The decline of the four concepts seemed to be caused by a poor awareness of managers in the coal industry that safety creates economic benefits, insufficient information on safety, inadequate attention to the development of a safety culture and safety management methods, and safety organizations and workers′ unions not playing their role effectively. Practical Applications: We therefore recommend strengthening the evidence that safety creates economic benefits, providing incentives for employees to encourage their participation in safety management, and paying more attention to the prevention of accidents in coal mines via safety organizations and unions. These results can provide guidelines for workers, industrialists, and government regarding occupational safety in the whole coal industry. PMID:27869654

Eskin, Mehmet

2003-02-01

The present cross-cultural study compared self-reported assertiveness in 652 Swedish and 654 Turkish high school students by using a multi-dimensional measure called the Scale for Interpersonal Behavior (SIB). Four hypotheses were tested in the study. First, the hypothesis that Swedish adolescents would be more assertive than their Turkish counterparts was supported by the data. Second, the expectation that Turkish boys would be more assertive than Turkish girls, while there would be no differences between Swedish girls and boys, was not confirmed. In general, girls were found to be more skilled than boys in expressing and dealing with personal limitations. Third, as expected, more assertive adolescents in both Sweden and Turkey reported having more friends and receiving more social support than their less assertive peers. Finally, the data supported the expectation that older adolescents would be more assertive than younger ones. The results are discussed in terms of cultural and gender differences.

The aim of the present study was to reveal the cross-cultural utility of the Thought-Action Fusion Scale (TAFS; J. Anxiety Disord. 10 (1996) 379). Thought-action fusion (TAF) refers to the tendency to overvalue the significance and the consequences of thoughts. Two hundred and fifty one undergraduate Turkish students participated in the current study. The reliability and validity analyses of the Turkish version of the scale indicated that the TAFS had adequate psychometric properties in a Turkish sample. Consistent with the original TAF, the Turkish version of TAFS revealed two subscales as TAF-Likelihood and TAF-Morality. Reliability analysis showed that TAF Scale and its factors had adequate internal consistencies and split-half reliability coefficients. Confirming the expectations, TAFS scores were found to be significantly and positively correlated with obsessive-compulsive symptoms, responsibility, and guilt measures. Moreover, it was found that people with high obsessive-compulsive symptoms had higher TAFS scores than those with low symptoms.

[Domestic violence, parenting styles and well-being of German and Turkish juveniles].

Uslucan, Haci-Halil

2009-01-01

This intercultural comparative study tries to identify the influences of domestic violence and parenting styles on juvenile violence and the well-being of juveniles. To this end, 304 German and 214 Turkish pupils in Berlin at the age of 13 to 16 completed a standardised questionnaire in their schools. The results show that Turkish juveniles report more harsh parenting styles than their German age-mates, but by controlling statistically the educational background of the parents, these differences disappear. Nevertheless, as a stable finding, we can hold that Turkish parents demand from their children a more cultural appropriate and disciplined behaviour. Furthermore, regarding the rates of juvenile violence, the main differences are seen in violence-legitimating attitudes and witnessing parental violence in the Turkish group. Lastly, in the relations between parenting styles and violence, there seems to be no culturally different patterns, but more differences in the intensity of disadvantaging consequences of punishing and harsh parenting on the well-being of juveniles.

Full Text Available The mindfulness approach to psychotherapy has become a topic of continuously growing scientific interest. In accordance with such interest, various self-report assessment tools have been developed to measure the mindfulness construct. The majority of the studies conducted to investigate the properties of these assessment instruments included Western populations. Thus, the measurement of mindfulness in non-Western cultures still requires further research. Based on this premise, the psychometric properties of the 10 item Cognitive and Affective Mindfulness Scale-Revised (CAMS-R were investigated in two different studies using two non-clinical Turkish samples. In Study 1, the psychometric properties of the 10 item CAMS-R were examined in an undergraduate student sample (N = 265. Study 2 extended the examination of the psychometric properties of the CAMS-R to an adult community sample consisting of white-collar public employees (N = 88. The results of both studies showed that the Turkish CAMS-R possessed acceptable levels of internal consistency and the scale displayed convergent as well as concurrent validity. Statistically meaningful relationships were found between mindfulness as measures by Turkish CAMS-R and depression, anxiety, well-being as well as perceived stress. The findings from both studies suggest CAMS-R retains its psychometric properties when utilized in a non-Western culture and the Turkish version of CAMS-R is a valid instrument which can be used to measure mindfulness in the Turkish population.

Pakistan contains huge reserves of lignitic coals. These are high sulphur, high ash coals. In spite of this unfortunate situation, the heavy demand for energy production, requires the development utilization of these indigenous coal reserves to enhance energy production. The central of the environmental pollution caused by the combustion of these coals has been a major hindrance in their utilization. Recently a substantial reduction in coal combustion emissions have been achieved through the development of clean coal technologies. Pakistan through the transfer and adaptation of the advanced clean coal technologies can utilize incurring the high sulphur coals for energy production without incurring the environmental effects that the developed countries have experienced in the past. The author discusses the recently developed clean coal utilization technologies, their applications economies and feasibility of utilization with specific reference to Pakistan''s coal. (author)

Igbinigie, Eric E; Mutambanengwe, Cecil C Z; Rose, Peter D

2010-03-01

Fundamental processes involved in the microbial degradation of coal and its derivatives have been well documented. A mutualistic interaction between plant roots and certain microorganisms to aid growth of plants such as Cynodon dactylon (Bermuda grass) on hard coal dumps has recently been suggested. In the present study coal bioconversion activity of nonmycorrhizal fungi was investigated in the C. dactylon/coal rhizosphere. Fungal growth on 2% Duff-agar, gutation formation on nitric acid treated coal and submerged culture activity in nitrogen-rich and -deficient broth formed part of the screening and selection of the fungi. The selected fungal isolates were confirmed to be found in pristine C. dactylon/coal rhizosphere. To simulate bioconversion, a fungal aliquot of this rhizosphere was used as inoculum for a Perfusate fixed bed bioreactor, packed with coal. The results demonstrate an enhanced coal bioconversion facilitated by low molecular weight organics and the bioconversion of coal may be initiated by an introduction of nitrogen moieties to the coal substrate. These findings suggest a phyto-bioconversion of hard coal involving plant and microbes occurring in the rhizosphere to promote the growth of C. dactylon. An understanding of this relationship can serve as a benchmark for coal dumps rehabilitation as well as for the industrial scale bioprocessing of hard coal.

The purpose of this study is to quantitatively evaluate behaviors of ash deposition during combustion of Upgraded Brown Coal (UBC) and bituminous coal in a 145 MW practical coal combustion boiler. A blended coal consisting 20 wt% of the UBC and 80 wt% of the bituminous coal was burned for the combustion tests. Before the actual ash deposition tests, the molten slag fractions of ash calculated by chemical equilibrium calculations under the combustion condition was adopted as one of the indices to estimate the tendency of ash deposition. The calculation results showed that the molten slag fraction for UBC ash reached approximately 90% at 1,523 K. However, that for the blended coal ash became about 50%. These calculation results mean that blending the UBC with a bituminous coal played a role in decreasing the molten slag fraction. Next, the ash deposition tests were conducted, using a practical pulverized coal combustion boiler. A water-cooled stainless-steel tube was inserted in locations at 1,523 K in the boiler to measure the amount of ash deposits. The results showed that the mass of deposited ash for the blended coal increased and shape of the deposited ash particles on the tube became large and spherical. This is because the molten slag fraction in ash for the blended coal at 1,523 K increased and the surface of deposited ash became sticky. However, the mass of the deposited ash for the blended coal did not greatly increase and no slagging problems occurred for 8 days of boiler operation under the present blending conditions. Therefore, appropriate blending of the UBC with a bituminous coal enables the UBC to be used with a low ash melting point without any ash deposition problems in a practical boiler.

Rosebud SynCoal Partnership, SynCoal{reg_sign} demonstration technology update

Energy Technology Data Exchange (ETDEWEB)

Sheldon, R.W. [Rosebud SynCoal Partnership, Billings, MT (United States)

1997-12-31

An Advanced Coal Conversion Process (ACCP) technology being demonstrated in eastern Montana (USA) at the heart of one of the world`s largest coal deposits is providing evidence that the molecular structure of low-rank coals can be altered successfully to produce a unique product for a variety of utility and industrial applications. The product is called SynCoal{reg_sign} and the process has been developed by the Rosebud SynCoal Partnership (RSCP) through the US Department of Energy`s multi-million dollar Clean Coal Technology Program. The ACCP demonstration process uses low-pressure, superheated gases to process coal in vibrating fluidized beds. Two vibratory fluidized processing stages are used to heat and convert the coal. This is followed by a water spray quench and a vibratory fluidized stage to cool the coal. Pneumatic separators remove the solid impurities from the dried coal. There are three major steps to the SynCoal{reg_sign} process: (1) thermal treatment of the coal in an inert atmosphere, (2) inert gas cooling of the hot coal, and (3) removal of ash minerals. When operated continuously, the demonstration plant produces over 1,000 tons per day (up to 300,000 tons per year) of SynCoal{reg_sign} with a 2% moisture content, approximately 11,800b Btu/lb and less than 1.0 pound of SO{sub 2} per million Btu. This product is obtained from Rosebud Mine sub-bituminous coal which starts with 25% moisture, 8,600 Btu/lb and approximately 1.6 pounds of SO{sub 2} per million Btu.

Self-scrubbing coal

International Nuclear Information System (INIS)

Kindig, J.K.

1992-01-01

More than 502 million tons - 65 percent of all coal shipped to utilities in 1990 - were above 1.2 pounds of sulfur dioxide per million Btu. Most of the coal, even though cleaned in conventional coal preparation plants, still does not meet the emission limitation the Clean Air Act Amendments mandate for the year 2000. To cope with this fact, most utilities plan to switch to low sulfur (western U.S. or Central Appalachian) coal or install scrubbers. Both solutions have serous drawbacks. Switching puts local miners out of work and weakens the economy in the utility's service territory. Scrubbing requires a major capital expenditure by the utility. Scrubbers also increase the operating complexity and costs of the generating station and produce yet another environmental problem, scrubber sludge. Employing three new cost-effective technologies developed by Customer Coals International (CCl), most non-compliance coals east of the Mississippi River can be brought into year-2000 compliance. The compliance approach employed, depends upon the characteristics of the raw coal. Three types of raw coal are differentiated, based upon the amount of organic sulfur in the coals and the ease (or difficultly) of liberating the pyrite. They are: Low organic sulfur content and pyrite that liberates easily. Moderate organic sulfur content and pyrite that liberates easily. High organic sulfur content or the pyrite liberates with difficulty. In this paper examples of each type of raw coal are presented below, and the compliance approach employed for each is described. The names of the beneficiated coal products produced from each type of raw coal give above are: Carefree Coal, Self-Scrubbing Coal and Dry-Scrubbing Coal

Novel approach for extinguishing large-scale coal fires using gas-liquid foams in open pit mines.

Coal fires are a serious threat to the workers' security and safe production in open pit mines. The coal fire source is hidden and innumerable, and the large-area cavity is prevalent in the coal seam after the coal burned, causing the conventional extinguishment technology difficult to work. Foams are considered as an efficient means of fire extinguishment in these large-scale workplaces. A noble foam preparation method is introduced, and an original design of cavitation jet device is proposed to add foaming agent stably. The jet cavitation occurs when the water flow rate and pressure ratio reach specified values. Through self-building foaming system, the high performance foams are produced and then infused into the blast drilling holes at a large flow. Without complicated operation, this system is found to be very suitable for extinguishing large-scale coal fires. Field application shows that foam generation adopting the proposed key technology makes a good fire extinguishment effect. The temperature reduction using foams is 6-7 times higher than water, and CO concentration is reduced from 9.43 to 0.092‰ in the drilling hole. The coal fires are controlled successfully in open pit mines, ensuring the normal production as well as the security of personnel and equipment.

Full Text Available Music Information Retrieval (MIR has become a popular research area in recent years. In this context, researchers have developed music information systems to find solutions for such major problems as automatic playlist creation, hit song detection, and music genre or mood classification. Meta-data information, lyrics, or melodic content of music are used as feature resource in previous works. However, lyrics do not often used in MIR systems and the number of works in this field is not enough especially for Turkish. In this paper, firstly, we have extended our previously created Turkish MIR (TMIR dataset, which comprises of Turkish lyrics, by including the audio file of each song. Secondly, we have investigated the effect of using audio and textual features together or separately on automatic Music Genre Classification (MGC. We have extracted textual features from lyrics using different feature extraction models such as word2vec and traditional Bag of Words. We have conducted our experiments on Support Vector Machine (SVM algorithm and analysed the impact of feature selection and different feature groups on MGC. We have considered lyrics based MGC as a text classification task and also investigated the effect of term weighting method. Experimental results show that textual features can also be effective as well as audio features for Turkish MGC, especially when a supervised term weighting method is employed. We have achieved the highest success rate as 99,12\\% by using both audio and textual features together.

The application of the coal grain analysis method to coal liberation studies

Energy Technology Data Exchange (ETDEWEB)

2011-07-01

Emerging coal markets such as the use of coal for conversion to liquid fuels and its use in fuels cells and as coal water slurries in diesel engines require coal products with different coal quality specifications than those applicable to traditional coal markets of coke making and conventional power generation. As well as quantifying coals in terms of their chemical and physical properties, detailed knowledge of the mineral inclusions within the coal particles is required to identify coals that are suited to economically produce the low-ash value coals required for these markets. After mining and processing, some particles can consist of essentially pure components of a single maceral or mineral phase whilst others are composite particles that are comprised of varying amounts of macerals and minerals. The proportion of particles that are present as pure components or as composites will be a function of the characteristics of the coal and the particle size. In general, it is considered that size reduction will result in liberation and hence increased yield. The amount of liberation that occurs during crushing or grinding a coal is however coal specific. Particle characterization information provided by an optical microscopic-imaging method, Coal Grain Analysis, was used to identify coals that might benefit from additional crushing to improve recovery of clean coal by new density separation techniques and by flotation. As expected, the results of these studies suggest that the degree of liberation that is obtained is coal specific, and, hence, yield improvements are also coal specific. Hence a quantitative method of investigating this issue is required.

Full Text Available Identity formation efforts of the EU draw attentionin Turkey’s membershipprocess. This paper is based on a hypothesis that identity, culture, norms andvalues which construct the social structure affectEuropean and Turkish identityinteraction. In the paper, right and left views within the Turkish parliament andEuropean parliament will be analyzed in the framework of social constructivism.Social constructivism which is provided as an alternative area of study in thesocial sciences to the European integration, is still evaluated as a debatedapproach in the internatioal relations literature.Wendt, Checkel, Smith,Katzenstein, Keohane and Krasner define social constructivism as an approachbetween rationalism represented with neo-realism, neo-liberalism and neo-liberalinstitutionalism- and reflectivism represented withpost-modernism and post-structuralism. On the other hand, some other authors evaluate socialconstructivism within the critical theories. This paper is based on the firstdefinition.The first assumption of the social constructivism asserts that material structuresshould be observed beyond the biological facts(Jupille, Caporaso, Checkel,2003.According to this asumption, material structures gain importance by interpretingwithin the social conditions and environment. By following this assumption, thispaper will focus on different foreign policy strategies of Turkey and Europe as aresult of different identity perceptions. The second assumption points to the natureof the actors and their relations with the institutional environment. In accordancewith this assumption, opinions, values and discourses of the party groups in theTurkish parliament and European parliament will betaken into consideration.Social constructivism stresses on the social interaction of the states and non-state actors. In this respect analyzing the social interaction within the framework ofTurkish-European identity will make a contributionto the literature.

Briquette coal has been widely used for domestic cooking and heating in many Chinese cites over the last two decades. To determine whether burning briquette coal contributes significantly to indoor air pollution, a study was performed in cities-of Southern China in which the measured levels of SO{sub 2}, NO{sub x}, TSP, SD, B(a)P in the kitchens of coal burning families were compared with levels obtained in families using gas. Significantly higher contentions of these pollutants, whose peaks correlated with daily cooking episodes, were detected in coal burning families. The levels of TSP and B(a)P were further found to be dependent on cooking methods, with deep frying and stir-frying of meat generating the most indoor TSP and B(a)P. Briquette coal burning was found to be the source of B(a)P contamination in food. A higher incidence of chronic pharyngitis as well as a suppressed salivary bacteriolytic enzyme activity were found in children of coal burning families. Epidemiologic and laboratory studies also show a close association between coal burning and the incidence of lung cancer in females. (author)

Diseases associated with coal mine dust continue to affect coal miners. Elucidation of initial pathological changes as a precursor of coal dust-related diffuse fibrosis and emphysema, may have a role in treatment and prevention. To identify the precursor of dust-related diffuse fibrosis and emphysema. Birefringent silica/silicate particles were counted by standard microscope under polarized light in the alveolar macrophages and fibrous tissue in 25 consecutive autopsy cases of complicated coal worker's pneumoconiosis and in 21 patients with tobacco-related respiratory bronchiolitis. Coal miners had 331 birefringent particles/high power field while smokers had 4 (pcoal miner had intra-alveolar macrophages with silica/silicate particles and interstitial fibrosis ranging from minimal to extreme. All coal miners, including those who never smoked, had emphysema. Fibrotic septa of centrilobular emphysema contained numerous silica/silicate particles while only a few were present in adjacent normal lung tissue. In coal miners who smoked, tobacco-associated interstitial fibrosis was replaced by fibrosis caused by silica/silicate particles. The presence of silica/silicate particles and anthracotic pigment-laden macrophages inside the alveoli with various degrees of interstitial fibrosis indicated a new disease: coal mine dust desquamative chronic interstitial pneumonia, a precursor of both dust-related diffuse fibrosis and emphysema. In studied coal miners, fibrosis caused by smoking is insignificant in comparison with fibrosis caused by silica/silicate particles. Counting birefringent particles in the macrophages from bronchioalveolar lavage may help detect coal mine dust desquamative chronic interstitial pneumonia, and may initiate early therapy and preventive measures.

Asia's coal and clean coal technology market potential

International Nuclear Information System (INIS)

Johnson, C.J.; Binsheng Li

1992-01-01

The Asian region is unique in the world in having the highest economic growth rate, the highest share of coal in total primary energy consumption and the highest growth rate in electricity generation capacity. The outlook for the next two decades is for accelerated efforts to control coal related emissions of particulates and SO 2 and to a lessor extent NO x and CO 2 . Only Japan has widespread use of Clean Coal Technologies (CCTs) however a number of economies have plans to install CCTs in future power plants. Only CCTs for electricity generation are discussed, and are defined for the purpose of this paper as technologies that substantially reduce SO 2 and/or NO x emissions from coal-fired power plants. The main theses of this paper are that major increases in coal consumption will occur over the 1990-2010 period, and this will be caccompanied by major increases in coal related pollution in some Asian economies. Coal fired electricity generation is projected to grow at a high rate of about 6.9 percent per year over the 1990-2010 period. CCTs are projected to account for about 150 GW of new coal-fired capacity over the 1990-2010 period of about one-third of all new coal-fired capacity. A speculative conclusion is that China will account for the largest share of CCT additions over the 1990-2010 period. Both the US and Japan have comparative advantages that might be combined through cooperation and joint ventures to gain a larger share of the evolving CCT market in Asia. 5 refs., 7 figs., 4 tabs

The report deals mainly with coal consumption, but also gives some information about technology, environmental aspects and markets. Data have been collected by questionnaires or via telephone. The use of steam coal for heating was 0.8 Mtons (down 20% from 1994). Cogeneration plants were the main users. Taxes and environmental reasons cause a reduction of the coal use that will probably continue the next years. Use of steam coal in industry has been constant at a level of 0.7 Mtons. The import of metallurgical coal rests constant at a level of 1.6 Mtons. 1.2 Mtons of coke was produced, and 0.3 Mtons imported. The PFBC-plant at Vaertan, Stockholm used 0.13 Mtons of coal, while some coal fired power plants have been converted to peat and wood fuels. The average price of steam coal imported to Sweden in 1995 was 333 SEK/ton, 6% higher than in 1994. The contract prices for delivery 1996 are about the same as at the end of 1995. All cogeneration plants have some sort of SO 2 removal system, mostly wet-dry. The largest plant, at Vaesteraas, has recently invested in a SCR system for NO x removal. Most other plants are using low NO x burners or SNCR systems, based on ammonia or urea, which reduce the emissions 50 - 70%. Some statistic about the world coal market is also given in the report

Turkish nuclear legislation: Developments for a nuclear newcomer

International Nuclear Information System (INIS)

Ercan, Erinc; Schneider, Horst

2013-01-01

The scope of legal investigation in this article focuses on nuclear legislation with regard to siting, construction, operation and decommissioning of NPPs, taking into account the main issues of nuclear safety, security, safeguards, radiological protection and nuclear third party liability. The state of existing legislation and, furthermore, of drafts published or announced related to substantive regulations and organisational aspects are at the centre of this article. International conventions and agreements, national legislation consisting of the constitution, laws, decrees and regulations as binding norms and otherwise, directives and non-binding guides provide the legal structure for nuclear activities. The evaluation of Turkish nuclear legislation with regard to the accomplishment of the obligations under, in particular, the CNS and Euratom directives, leads finally to the perspective on the specific issues that should be addressed in the regulation of nuclear energy for Turkey's future energy needs and to ensure conformity with international standards of the International Atomic Energy Agency (IAEA) and the OECD Nuclear Energy Agency (NEA). A brief discussion of Turkish energy legislation and institutional structure is necessary, because NPPs also need a licence for electricity production under Turkey's energy legislation. The Turkish government is aiming for greater privatisation in the energy sector. The current electricity market is governed, on the one hand, by the Electricity Market Law and Electricity Market License Regulation, which requires NPPs to have an electricity production licence and, on the other hand, by specific institutions. In terms of the Electricity Market Law, private legal entities who wish to obtain an electricity generation licence must 'be established as incorporated or limited liability companies in accordance with the provisions of the Turkish Commercial Law'. The relevant institutions in Turkey's energy sector include: the Energy

Full Text Available Through survey results, this study evaluated global trends’ effects on Turkish kitchen furniture production. The level of knowledge and difficulties of catching up with and implementing developmental trends in the Turkish kitchen furniture sector has been seen as having a structure equivalent to world standards because the level of material and technological development has been determined by four criteria: consumer demand, housing plans, technology inadequacy, and material inadequacy. According to the results, findings in this framework, consumer demand was most influential (45.4% in capturing and implementing enterprises’ trends. Evaluation results on kitchen furniture projects implemented by Turkish enterprises within the last 5 years showed that they mostly worked with models with one-lid views in cabinet-door applications (41.6%. As a result, world trends reflect the direct influence of Turkish kitchen furniture manufacturers on cabinet-door models and color preferences for kitchen units.

The swelling behavior in different solvents of 4 bituminous coals with different ranks and their residues from extraction by CS{sub 2}/NMP mixed solvent (l:1 in volume) were measured. The change in swelling property of the four coals thermally treated at different temperature was observed. The results show that the swelling ratio decreases with increasing rank of coal. For lower rank bituminous coals the swelling ratios in polar solvent are higher than those in non-polar solvent, and this difference decreases with increasing rank. The cross-linking densities of the four residues decrease, and the swelling ratios increase compared with those of raw coals. The swelling ratios of the four thermally treated coals under 150{sup o}C in CS{sub 2} increase, suggesting the decrease in crosslinking density of them. When the thermal treatment temperature increases to 240{sup o}C, the swelling rations of the other three coals in NMP and CS{sub 2} increase again except gas coal, demonstrating the further decrease in crosslinking density. This result is coincident with the extraction yield change in the mixed solvent of the thermally treated coal. For example, the extraction yield of lean coal treated at 240{sup o}C increases from 6.9% to 17.3%. FT-IR results show the removal of oxygen group of the thermally treated coals. This may explain the increase in swelling ratio and extraction yield in the mixed solvent of coal after thermal treatment. The cross-linking density of the thermally treated coal decreases because of the break of hydrogen bonds due to removal of C = 0 and -OH oxygen groups during the thermal treatment, resulting in the increases of swelling ratio and extraction yield in the mixed solvent of thermally treated coal compared with those of raw coal. 15 refs., 3 figs., 6 tabs.

2008-10-01

VR technologies, which generate immersive, interactive, and three-dimensional (3D) environments, are seldom applied to coal mine safety work management. In this paper, a new method that combined the VR technologies with underground mine safety management system was explored. A desktop virtual safety management program for underground coal mine, called VRLane, was developed. The paper mainly concerned about the current research advance in VR, system design, key techniques and system application. Two important techniques were introduced in the paper. Firstly, an algorithm was designed and implemented, with which the 3D laneway models and equipment models can be built on the basis of the latest mine 2D drawings automatically, whereas common VR programs established 3D environment by using 3DS Max or the other 3D modeling software packages with which laneway models were built manually and laboriously. Secondly, VRLane realized system integration with underground industrial automation. VRLane not only described a realistic 3D laneway environment, but also described the status of the coal mining, with functions of displaying the run states and related parameters of equipment, per-alarming the abnormal mining events, and animating mine cars, mine workers, or long-wall shearers. The system, with advantages of cheap, dynamic, easy to maintenance, provided a useful tool for safety production management in coal mine.

Nash, J. [South Blackwater Coal Limited, Blackwater, Qld. (Australia)

1998-09-01

The South Blackwater operation consists of two opencut mining areas and two underground mines (Laleham and Kenmure) near Blackwater in central Queensland, all of which supply coal to a central coal preparation plant. South Blackwater Coal Ltd. recently developed a maintenance improvement programme, described in this article. The programme involved implementation systems of key performance indicators (KPIs), benchmaking, condition monitoring, work planning and control, failure analysis and maintenance audit. Some improvements became almost immediately apparent, others were quite gradual. Major results included: improved availability (and reliability) of all opencast fleets, improvements in rear dump availability; reduced maintenance man-hours for opencast fleets; and increased availability of the coal handling and preparation plant. The paper is an edited version of that presented at the `Maintenance in mining conference` 16-19 March 1998, held in Bali, Indonesia. 4 figs., 2 photos.

Hard coal; Steinkohle

Energy Technology Data Exchange (ETDEWEB)

Loo, Kai van de; Sitte, Andreas-Peter [Gesamtverband Steinkohle e.V., Herne (Germany)

2013-04-01

The year 2012 benefited from a growth of the consumption of hard coal at the national level as well as at the international level. Worldwide, the hard coal still is the number one energy source for power generation. This leads to an increasing demand for power plant coal. In this year, the conversion of hard coal into electricity also increases in this year. In contrast to this, the demand for coking coal as well as for coke of the steel industry is still declining depending on the market conditions. The enhanced utilization of coal for the domestic power generation is due to the reduction of the nuclear power from a relatively bad year for wind power as well as reduced import prices and low CO{sub 2} prices. Both justify a significant price advantage for coal in comparison to the utilisation of natural gas in power plants. This was mainly due to the price erosion of the inexpensive US coal which partly was replaced by the expansion of shale gas on the domestic market. As a result of this, the inexpensive US coal looked for an outlet for sales in Europe. The domestic hard coal has continued the process of adaptation and phase-out as scheduled. Two further hard coal mines were decommissioned in the year 2012. RAG Aktiengesellschaft (Herne, Federal Republic of Germany) running the hard coal mining in this country begins with the preparations for the activities after the time of mining.

The authors examined the prevalence of chronic procrastination (decisional, avoidant, and arousal styles) as functions of demographic variables among 354 Turkish adults (148 men, 206 women; M age = 38.7 years, SD = 8.26 years). Prevalence analyses showed that among Turkish participants, 17.5% were indecisive procrastinators, 13.8% were avoidant procrastinators, and 14.7% were arousal procrastinators. Results did not yield significant differences for gender or age on any forms of procrastination, which is consistent with other international samples. However, significant differences emerged depending on the number of children such that Turkish adults who had more than 3 children claimed to be more indecisive than they claimed to be arousal or avoidant procrastinators. Respondents with less than a graduate degree reported higher rates of indecision than did respondents with at least a graduate degree.

Today, human genetic information is used for commercial purposes as well. This means, based on the case, the direct or indirect commercialization of genetic information. In this study, this specific issue is analyzed in light of the new legal regulations as to the subject in the Turkish Law. Specifically, this study focuses on the issue of whether the commercialization of genetic information is allowed under the Turkish Law. This study also attempts to clarify the issue of whether there is any limitations for the commercialization of genetic information in the Turkish Law provided that the commercialization of genetic information is permitted. Prior to this legal analysis, the problems of the legal ownership for genetic information and of whether genetic information should be considered as an organ of human body is discussed. Accordingly, relevant Turkish laws and regulations are individually analyzed within this context. In the mean time legal regulations of some countries in this respect are taken into account with a comparative approach. In the end a general evaluation and suggestions are provided to the reader.

Coal prices rise

2001-01-01

Coking and semi hard coking coal price agreements had been reached, but, strangely enough, the reaching of common ground on semi soft coking coal, ultra low volatile coal and thermal coal seemed some way off. More of this phenomenon later, but suffice to say that, traditionally, the semi soft and thermal coal prices have fallen into place as soon as the hard, or prime, coking coal prices have been determined. The rise and rise of the popularity of the ultra low volatile coals has seen demand for this type of coal grow almost exponentially. Perhaps one of the most interesting facets of the coking coal settlements announced to date is that the deals appear almost to have been preordained. The extraordinary thing is that the preordination has been at the prescience of the sellers. Traditionally, coking coal price fixing has been the prerogative of the Japanese Steel Mills (JSM) cartel (Nippon, NKK, Kawasaki, Kobe and Sumitomo) who presented a united front to a somewhat disorganised force of predominantly Australian and Canadian sellers. However, by the time JFY 2001 had come round, the rules of the game had changed

Speech and language assessment is very important in early diagnosis of children with hearing and speech disorders. Aim of this study is to determine the validity and reliability of Preschool Language Scale (5th edition) test with its Turkish translation and adaptation. Our study is conducted on 1320 children aged between 0-7 years 11 months. While 1044 of these children have normal hearing, language and speech development, 276 of them have receptive and/or expressive language disorder. After the English-Turkish and Turkish-English translations of PLS-5 made by two experts command of both languages, some of the test items are reorganized because of the grammatical features of Turkish and the cultural structure of the country. The pilot study was conducted with 378 children. The test which is reorganized in the light of data obtained in pilot application, is applied to children chosen randomly with layering technique from different regions of Turkey, then 15 days later the first test applied again to 120 children. While 1044 of 1320 children aged between 0 and 7 years 11 months are normal, 276 of them have receptive and/or expressive language disorder. While 98 of 103 healthy children of 120 taken under the second evaluation have normal language development, 8 of 9 who used to have language development disorder in the past still remaining (Kappa coefficient:0,468, page equivalance is found as IA:0,871, IED: 0,896, TDP: 0,887. TPLS-5 is the first and only language test in our country that can evaluate receptive and/or expressive language skills of children aged between 0-7 years 11 months. Results of the study show that TPLS-5 is a valid and reliable language test for the Turkish children. Copyright © 2017. Published by Elsevier B.V.

Kus, Jolanta; Meyer, Uwe; Ma, Jianwei; Chen-Brauchler, Dai

2010-05-01

At the coalfield of Wuda (Inner Mongolia, PR China) extensive underground coal fires cause widespread thermal and oxidative effects in coal seams. Within phase B of the Coal Fire Research Project of the Sino-German Initiative, methods for innovative fire-extinguishing technologies were investigated in multifaceted research approaches. Extensive investigations of oxidative and thermally affected coal seams in coal fire zone 18 were conducted in 2008 prior to application of new fire-extinguishing methods. We present results from the outcrop of coal seam No. 4 in the fire zone 18. The coal of seam No. 4 is of Early Permian age and belongs stratigraphically to the Shanxi Formation. The unaffected coal displays a high volatile bituminous A rank with a background value of random vitrinite reflectance ranging from 0.90 to 0.96 % Rr. Coal channel samples were coallected at actively extracted coal faces along multiple profiles with surface temperatures ranging from about 50° to 600°C. Microscopic examinations revealed a variety of products of coal exposure to the fire. Within coal samples, a marked rise in vitrinite reflectance from background values to 5.55% Rr (6.00 % Rmax) is encountered. In addition, a number of coal samples showed suppressed vitrinite reflectances ranging between 0.82 to 0.88% Rr. Further, seemingly heat unaffected coal samples display intensive development of oxidations rims at coal grain edges and cracks as well as shrinkage cracks and formation of iron oxides/hydroxides. Instead, thermally affected coal samples with higher coalification grade are further characterised by development of macropores (devolatilisation pores) in vitrinitic streaks, transformation of liptinite to meta-liptinite and micrinite as well as by natural coke particles of mostly porous nature and fine to coarse grained anisotropic mosaic. Coal petrographic investigations confirmed a hypothesis that both, oxidations as well as low temperature carbonisation govern the thermal

Coal -98

The following report deals with the use of coal and coke during 1997. Some information about technic, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from SCB have also been used. The use of steam coal for heating purposes during 1997 was 730 000 tons and about 500 000 tons lower than in 1996. The extremely high figures of 1996 were due to twice the production of electricity because of lack of hydro power. The co-generation plants were the main users of coal. The minor plants have increased their use of forest fuels. Probably the use of steam coal will go down in the immediate years both in the heat generating and the co-generating plants. Some foreign analysts, however, estimate a doubled use of coal for energy use after 2020 because of the plans to phase out the nuclear power. During the top year 1987 coal was used in 18 hot water plants and 11 co-generation plants. 1997 these figures are 2 and 8. Taxes and environmental reasons explain this trend. The use of steam coal in the industry has been constant at the level 700 000 tons. This level is supposed to be constant or to vary with business cycles. The import of metallurgical coal in 1997 was 1.6 mill tons like the year before. 1.2 mill tons coke were produced. The coke consumption in the industry was 1.5 Mill tons. 0.3 mill tons of coke were imported. Several other plants have plans to replace the coal with forest fuels, waste fuels and NG. Even the biggest plant, Vaesteraas, has plans to build a block for bio fuels. Helsingborg has started to use wood pellets. The pellets replace most of the coal for the heat production in the co-generation plant. Norrkoeping Kraft AB has taken a fluid bed boiler for different fuels in operation, leading to more than half the coal consumption compared with previous years. They have also rebuilt one of their travelling grates for bio fuels. Stockholm

Full text: The Turkey has very important natural stones potential with over 5 billion m 3 marble reserves. According to 2002 giving data the number of Turkish stones export is 303 million US Dollars. In this regards, the present study deals with 90 Turkish natural stones. The studied samples were analyzed and the concentrations in Bq/kg dry weight of radioisotopes were determined by gamma-ray spectrometry using HPGe detector. The radon exhalation rates of natural stones were also measured by using solid state nuclear track detectors (LR-115 ). The radium equivalent activity varied from 183 Bq/kg to 522 Bq/kg for granite samples and from 1 Bq/kg to 37 Bq/kg for marble samples. The value of radon exhalation rate ranged from 0.003 Bq/m 2 h -1 to 0.768 Bq/m 2 h -1 for granite samples and from 0.001 Bq/m 2 h -1 to 0.02 Bq/m 2 h -1 for marble samples. The total absorbed dose rates in air ranged from 22 to 61 n Gy h -1 for one quarter utilization of granite samples. The annual effective dose rates per person indoors were determined to be between 108 and 298 μSv y -1 for of for one quarter utilization of the materials. Applying the dose criteria recently recommended by UNSCEAR for building materials, the natural stones meet the upper dose limit of 1mSvy -1 . So, there are not restrictions for use of any Turkish commercial marble as covering materials, including Turkish granites. (author)

1979-03-01

Chemical and petrographic analysis was conducted on coals from the Anadyrya and Bukhti Ugol'noi deposits. Characteristics of the most prevalent type of vitrinite coals in both regions are presented here. Anadyrya coals belong to a transitional phase between brown coal and long flame. Ultravitrinite coals predominate. Gas coals from Bukti Ugol'noi have a higher carbon content than Anadyrya coals. They also have a higher hydrogen content and yield of initial resin. In several cases there was also a higher yield of volatile substances. Chukotka coals are characterized by a 10 percent higher initial resin yield than equally coalified Donetsk coals, other indicators were equal to those of Donetsk coals. Because of this, Chukotka coals are suitable for fuel in power plants and as raw materials in the chemical industry. (15 refs.) (In Russian)

Monitoring overweight in risk groups is necessary. Our aim is to assess the trend in overweight and obesity in Turkish and Moroccan children in the Netherlands since 1997 and to monitor the levels of lifestyle-related behaviours in 2009. We selected cross-sectional data of Turkish and Moroccan children aged 2-18 years from two national Growth Studies performed in 1997 and 2009 in the Netherlands. Lifestyle-related behaviours were obtained in the 2009 study by questionnaire. In 2009, 31.9% of Turkish and 26.6% of Moroccan children had overweight, whereas this was, respectively, 26.7% and 19.6% in 1997. Already at 2 years, 21.1% in Turkish and 22.7% in Moroccan children had overweight in 2009. The prevalence of obesity was above 4% from 3 years onwards. High (i.e. ≥ 25%) prevalence rates of unhealthy lifestyle-related behaviours were found for not having breakfast (26-49%) among Turkish and Moroccan adolescent (i.e. 15-18 years) girls, consuming no fruit (29-45%) and watching TV/PC ≥ 2 h (35-72%) among all Turkish and Moroccan adolescents, no walking/cycling to school/day care among preschool children (2-4 years) (28-56%) and adolescents (34-94%), drinking ≥ 2 glasses of sweet beverages (44-74%) and being children. An upward trend of overweight and obesity occurred in Turkish and Moroccan children. Already at 2 years of age, one out of five Turkish and Moroccan children had overweight, which calls for early prevention with attention to specific lifestyle-related behaviours. © The Author 2015.

2013-01-01

Measuring patient-reported outcomes has become increasingly important in cosmetic and reconstructive breast surgery. There is no validated questionnaire in Turkish to evaluate quality-of-life issues for patients with mammary hypertrophy. The authors describe the reliability and validity of a translated Breast Reduction Assessed Severity Scale (BRASS) in evaluating Turkish patients. The BRASS, developed by Sigurdson et al, was translated into Turkish adhering strictly to the guidelines of questionnaire translations. Statistical analysis was carried out with Cronbach's α to test the internal consistency and intraclass correlation coefficient for test-retest reliability. Exploratory factor analysis was carried out using principal component analysis with oblimin rotation to test its construct validity. Correlations between subscales identified in the factor analysis and corresponding domains in the Short Form-36 and Rosenberg Self-Esteem Scale were analyzed. The total instrument was found to have an α coefficient of 0.92 and subscale α coefficients ranging from 0.76 to 0.87. Intraclass correlation coefficient was 0.93 for the total scale and ranged from 0.81 to 0.91 for the subscales. Exploratory factor analysis resulted in a 5-factor structure: physical implications, body pain, physical appearance, poor self-concept, and negative social interactions. With this study, the reliability and validity of the Turkish version of the BRASS were revealed. This translated version can be used to evaluate the effect of mammary hypertrophy on quality of life in Turkish patients.

2017-12-01

Full Text Available Immigration studies still investigate immigrants’ offspring and later generations’ socioeconomic upward and downward motilities. When it comes to early Turkish immigrants, there is an unfilled “missing link” from a sociological point of view. This study explores early Turkish immigrants’ adaptation experiences in the United Sates through qualitative triangulation and the methods of observation. This article utilizes “Straight-line theory”, “decline theory”, and “segmented assimilation to expound early Turkish immigrants’ adaptation experiences in the United States. Drawing on archival documents next to meetings with immigrants’ off springs, this study finds evidence that immigration occurred during the second wave to the United States from Europe, among Turks from Anatolia and Rumelia and they successfully adapted their new social environment. Rather, the findings provide novel evidence on the role of religious view and their social interaction. When seeking early Turks’ socio educational background, we discover that highly educated individuals including religious leaders, professors, and businessmen migrated to Peabody, MA.

This final report presents the research work carried out on the Coal Surface Control for Advanced Physical Fine Coal Cleaning Technologies project, sponsored by the US Department of Energy, Pittsburgh Energy Technology Center (DOE/PETC). The project was to support the engineering development of the selective agglomeration technology in order to reduce the sulfur content of US coals for controlling SO[sub 2] emissions (i.e., acid rain precursors). The overall effort was a part of the DOE/PETCs Acid Rain Control Initiative (ARCI). The overall objective of the project is to develop techniques for coal surface control prior to the advanced physical fine coal cleaning process of selective agglomeration in order to achieve 85% pyrite sulfur rejection at an energy recovery greater than 85% based on run-of-mine coal. The surface control is meant to encompass surface modification during grinding and laboratory beneficiation testing. The project includes the following tasks: Project planning; methods for analysis of samples; development of standard beneficiation test; grinding studies; modification of particle surface; and exploratory R D and support. The coal samples used in this project include three base coals, Upper Freeport - Indiana County, PA, Pittsburgh NO. 8 - Belmont County, OH, and Illinois No. 6 - Randolph County, IL, and three additional coals, Upper Freeport - Grant County- WV, Kentucky No. 9 Hopkins County, KY, and Wyodak - Campbell County, WY. A total of 149 drums of coal were received.

The Chinese government has made many energy policies on coal, and coalmine methane (CMM) use. However, not all of these policies have effects or positive impacts. For example, it has been quite a few years since the national government made policies to encourage coalmine methane power to be sold to the grid. Practice showed that not any kilowatt of electricity was sold from a coalmine methane power plant to the grid in Sichuan and Guizhou Provinces as of December 2008. The objectives of this paper are to review and evaluate the Chinese government energy and climate policies that are related to coal and coalmine methane, analyze relevant policy barriers, and make recommendations to overcome these barriers and avoid policy failures. This paper provides the literature review, challenges, resources, policies and other updated information on China's CMM recovery and utilization. The paper concludes that China needs to further reform its energy and environment management system, engage provincial governments in CMM capture and use activities, and provide incentives to qualified engineers and skilled workers to work in remote coal mining areas. This paper transfers key messages to policy makers for them to make better CMM capture and use policies.

Canyurt, Olcay Ersel; Ozturk, Harun Kemal

2008-01-01

The main objective is to investigate Turkey's fossil fuels demand, projection and supplies by using the structure of the Turkish industry and economic conditions. This study develops scenarios to analyze fossil fuels consumption and makes future projections based on a genetic algorithm (GA). The models developed in the nonlinear form are applied to the coal, oil and natural gas demand of Turkey. Genetic algorithm demand estimation models (GA-DEM) are developed to estimate the future coal, oil and natural gas demand values based on population, gross national product, import and export figures. It may be concluded that the proposed models can be used as alternative solutions and estimation techniques for the future fossil fuel utilization values of any country. In the study, coal, oil and natural gas consumption of Turkey are projected. Turkish fossil fuel demand is increased dramatically. Especially, coal, oil and natural gas consumption values are estimated to increase almost 2.82, 1.73 and 4.83 times between 2000 and 2020. In the figures GA-DEM results are compared with World Energy Council Turkish National Committee (WECTNC) projections. The observed results indicate that WECTNC overestimates the fossil fuel consumptions. (author)

Full Text Available At the end of the First World War, the Ottoman Empire collapsed and the Great Powers came to take the control of its territories. Having a strategic position at the southern gate of Europe, all of Turkish lands were very important for the First World War winners, both to secure European borders and to develop the trade between Europe and Middle East. On the other side, under Mustafa Kemal Atatürk command, a new Turkey with a strong nationalist way decided to fight for emancipating. Winning the war with the Great Powers not only in a military way, but also from a diplomatic perspective, the new Turkey became a modern regional power, having institutions and laws that assured its prosperity and security. Taking into consideration the independence war evolution, this paper wants also to show the diplomatic capability of Turkish leaders to balance between powers involved in the region.

We aimed to find a prevalence of human papilloma virus (HPV) in order to define the 100 genotypes and subset of 14 oncogenic genotypes in pregnant Turkish women and to compare these with non-pregnant women. Cervical thin-prep specimens were obtained from 164 women in the first trimester pregnancy and 153 non pregnant women. 29.2% of pregnant versus 19.6% of non-pregnant Turkish women had at least one of the 100 types of HPV infection--a statistically significant difference. The rate of 14 high-risk HPV genotype infections was significantly higher in pregnant (14.6) compared to non-pregnant Turkish women (9.6%). Pregnant Turkish women are at higher risk for all HPV infections including high-risk cervical cancer genotypes.

Full Text Available The main purpose of Turkish language teaching is to foster students’ emotional, intellectual and imaginative worlds by means of text-based language studies and thus inculcation of language skills such as listening, speaking and writing in students. Given that Turkish language teaching texts are usually the starting point, for these skills to be imparted in students, importance should be attached to surface-deep and deep-surface relationships while studying texts and thus texts should be studied with the greatest emphasis put on not the detection of the main idea, but on the comprehension of the core and its connection with the internal and external world. The purpose of the current study is to determine the core finding skills of first-year undergraduate students from the Department of Turkish Language Teaching and to provide some insights for teachers and pre-service teachers into how to instill the skill of core finding. Within the context of the current study, 50 first-year students from the Department of Turkish Language Teaching of Muğla Sıtkı Koçman University, Turkey, during the 2015-2016 academic year were informed about the concepts of core and finding the core and they were asked to find and write the core of the text entitled “Morning Discussion at the Children’s Library” from a Turkish language textbook used in the sixth grade. Data was collected through the document analysis method and it was concluded that the students were unable to find the core; and that they could not reach the deep meanings, but only the superficial meanings.

Nowadays, there are many reasons for people to be stressful and restless in their working environments. One of the reasons leading to this situation is known as "mobbing". The term "mobbing" means "bullying of an individual by a group". It usually happens among employees. The main effects of mobbing are the generation of stress and reduction of employee performance at work. In general, research shows that mobbing is particularly common in the public sector. The aim of this research is to understand the frequency of mobbing on employees in the Turkish maritime industry as a case study. In this study, a questionnaire survey on ship, shipyard, public and private company workers was applied to understand how often employees are exposed to mobbing. After analysing the results, it is also aimed to obtain information about the reasons and causes of mobbing, and then we can get some advice for this issue.

2017-07-21

This study examined ethnic differences in ageing perceptions of migrant Turkish and native Dutch elders residing in Rotterdam, and explored whether such differences could be attributed to culture or resources (personal, physical, economic and/or social). This study was based on combined data from two research projects focusing on the health and well-being of community-dwelling elderly people in Rotterdam. The first dataset contained data from 994 native Dutch elders aged 70-99 years. The Rotterdam municipal register was used to randomly sample respondents, stratified by age group (70-74, 75-79, 80-84, and ≥85 years) and neighbourhood. Of the 2593 eligible respondents, 1075 returned filled-in questionnaires (41% response rate). Of these 1075 respondents a total of 994 were natives which is the sample we selected for the current study. The second dataset contained data from 680 Turkish migrants aged 65-90 years. All Turkish people aged ≥65 years were identified using the Rotterdam municipal register and invited to participate. In total, 680 Turkish respondents returned filled-in questionnaires (32% response rate; out of 2350). Ageing perceptions were measured using the 21-item Ageing Perceptions Questionnaire-Short (APQ-S). Respondents were additionally asked about their current general health, income, education, marital status, age and gender. The results of this study clearly reveal the importance of culture for all ageing perceptions among Turkish and Dutch elders. We found that age, health, and education were also important factors. For Turkish elders, health and education were the most important resources; for Dutch elders, age and health were most important in relation to ageing perceptions. Ageing perceptions were generally more negative among Turkish than among Dutch elders. Turkish elders reported more negative awareness of ageing, felt less in control of their ageing processes, and had more negative emotional reactions to ageing. They also believed

Ding, Xu; Shi, Lei; Han, Jianghong; Lu, Jingting

2016-01-01

Wireless sensor networks deployed in coal mines could help companies provide workers working in coal mines with more qualified working conditions. With the underground information collected by sensor nodes at hand, the underground working conditions could be evaluated more precisely. However, sensor nodes may tend to malfunction due to their limited energy supply. In this paper, we study the cross-layer optimization problem for wireless rechargeable sensor networks implemented in coal mines, of which the energy could be replenished through the newly-brewed wireless energy transfer technique. The main results of this article are two-fold: firstly, we obtain the optimal relay nodes’ placement according to the minimum overall energy consumption criterion through the Lagrange dual problem and KKT conditions; secondly, the optimal strategies for recharging locomotives and wireless sensor networks are acquired by solving a cross-layer optimization problem. The cyclic nature of these strategies is also manifested through simulations in this paper. PMID:26828500

The purpose of this study was to develop a Turkish version of the Berg Balance Scale (BBS) and assess its reliability and validity. Sixty healthy volunteers older than 65 years were included in to the study. Subjects who had lower extremity amputation, or were armchair or bedridden were excluded. After translation process, the Turkish version of the scale was administered to each participant twice with an interval of 2 weeks. The intraclass correlation coefficient (ICC) was calculated to assess intra- and inter-observer reliability. Chronbach alpha was calculated to evaluate internal consistency of the total BBS score. Interclass correlation coefficient was calcuated to examine test-retest reliability. Convergent validity was assessed by correlating the scale with Modified Barthel Index (MBI) and Timed Up and Go Test (TUG). Construct validity was assessed with factor analysis. The mean age in years of the participants were 77.00+/-5.67 (range: 67-92 yrs). The ICC for intra- and inter- observer reliability was 0.98 (pr=0.67 pr=-0.75 p<0.0001, respectively). The Turkish version of the BBS is a reliable and valid scale to be used in balance assessment of Turkish older adults.

Inorganic Constituents in Coal

Full Text Available Coal contains not only organic matter but also small amounts of inorganic constituents. More thanone hundred different minerals and virtually every element in the periodic table have been foundin coal. Commonly found group minerals in coal are: major (quartz, pyrite, clays and carbonates,minor, and trace minerals. Coal includes a lot of elements of low mass fraction of the orderof w=0.01 or 0.001 %. They are trace elements connected with organic matter or minerals comprisedin coal. The fractions of trace elements usually decrease when the rank of coal increases.Fractions of the inorganic elements are different, depending on the coal bed and basin. A varietyof analytical methods and techniques can be used to determine the mass fractions, mode ofoccurrence, and distribution of organic constituents in coal. There are many different instrumentalmethods for analysis of coal and coal products but atomic absorption spectroscopy – AAS is theone most commonly used. Fraction and mode of occurrence are one of the main factors that haveinfluence on transformation and separation of inorganic constituents during coal conversion.Coal, as an important world energy source and component for non-fuels usage, will be continuouslyand widely used in the future due to its relatively abundant reserves. However, there is aconflict between the requirements for increased use of coal on the one hand and less pollution onthe other. It’s known that the environmental impacts, due to either coal mining or coal usage, canbe: air, water and land pollution. Although, minor components, inorganic constituents can exert asignificant influence on the economic value, utilization, and environmental impact of the coal.

Mok, Sog Yee; Martiny, Sarah E; Gleibs, Ilka H; Keller, Melanie M; Froehlich, Laura

2016-01-01

Past research on ethnic composition effects on migrant and ethnic majority students' performance has reported inconclusive results: Some studies have found no relationship between the proportion of migrant students in school and students' performance, some revealed positive effects, whereas others showed negative effects of the proportion of migrant students. Most of the studies did not consider whether an increase in the proportion of migrant students in the classroom has different effects on migrant and ethnic majority students' performance. For this reason, the present study (N = 9215) extends previous research by investigating the cross-level interaction effect of the proportion of Turkish-origin students in classrooms on Turkish-origin and German students' reading performance with data based on the German National Assessment Study 2008/2009 in the school subject German. In addition, we examined the cross-level interaction effect of Turkish-origin students' proportion on sense of belonging to school for Turkish-origin and German students, as sense of belonging has been shown to be an important predictor of well-being and integration. No cross-level interaction effect on performance emerged. Only a small negative main effect of the Turkish-origin students' proportion on all students' performance was found. As predicted, we showed a cross-level interaction on sense of belonging. Only Turkish-origin students' sense of belonging was positively related to the proportion of Turkish-origin students: The more Turkish-origin students there were in a classroom, the higher Turkish-origin students' sense of belonging. German students' sense of belonging was not related to the ethnic classroom composition. Implications of the results in the educational context are discussed.

Material balance in coal. 2. Oxygen determination and stoichiometry of 33 coals

International Nuclear Information System (INIS)

1977-01-01

The chemical analysis of coal can be supplemented by the determination of oxygen in high and low temperature ash, in coal as received and in coal dried at 105 0 C. The rapid method utilizes fast-neutron activation. The reaction 16 O(n,p) 16 N and counting of the 6.1 and 7.1 MeV gammas of 7.3 second half-life are used. A specially designed dual transfer and simultaneous counting system gives very accurate results. Oxygen in 33 coals ranging from lignite to low volatile bituminous coal is determined and compared with ''oxygen by difference.'' Considerable discrepancies are observed. Better stoichiometric results are obtained if oxygen in coal ash, in wet coal and in the dried coal is determined. This permits the estimation of the true material balances using data of the ultimate and the proximate coal analysis. The oxygen determination provides the coal chemist with an accurate basis and can be used to rank coal. The summation of the percent of carbon, nitrogen, hydrogen, sulfur, and oxygen becomes more meaningful and some errors can be detected and the state of completeness of coal analysis thus evaluated. Total sulfur can be estimated and oxidation effects during drying can be detected. These affect the moisture determination. It appears that after more data are collected, the interpretation of solid fuel analyses may be facilitated and will be stoichiometrically more meaningful. It is shown that it may be possible to simplify the present time-consuming methods of coal analysis

Negative symptoms in schizophrenia have been assessed by many instruments. However, a current consensus on these symptoms has been built and new tools, such as the Brief Negative Symptom Scale (BNSS), are generated. This study aimed to evaluate reliability and validity of the Turkish version of BNSS. The scale was translated to Turkish and backtranslated to English. After the approval of the translation, 75 schizophrenia patients were interviewed with BNSS, Positive and Negative Syndrome Scale (PANSS), Calgary Depression Scale for Schizophrenia (CDSS) and Extrapyramidal Symptom Rating Scale (ESRS). Reliability and validity analyses were then calculated. In the reliability analysis, the Cronbach's alpha coefficient was 0.96 and item-total score correlation coefficients were between 0.655-0.884. The intraclass correlation coefficient was 0.665. The inter-rater reliability was 0.982 (p Symptoms Subscale, Negative Symptoms Subscale, and General Psychopathology Subscale. CDSS and ESRS were not correlated with BNSS-TR. The factor structure of the scale was consisting the same items as in the original version. Our study confirms that the Turkish version of BNSS is an applicable tool for the evaluation of negative symptoms in schizophrenia.

Shyness and cognitions: an examination of Turkish university students.

Koydemir, Selda; Demir, Ayhan

2008-11-01

The authors aimed to examine the relation between shyness and dysfunctional relationship beliefs and to extend findings of previous studies to understand the role of fear of negative evaluation and self-esteem in shyness. Participants were 415 Turkish undergraduate students at Middle East Technical University. The participants completed Turkish versions of the J. M. Cheek and A. H. Buss (1981) Shyness Scale, the Interpersonal Cognitive Distortions Scale (Z. Hamamci & S. Büyükoztürk, 2004) the Brief Fear of Negative Evaluation Scale (M. R. Leary, 1983), and the M. Rosenberg (1965) Self-Esteem Scale. Bivariate correlations showed that shyness had a significant positive correlation with unrealistic relationship expectations and interpersonal rejection. Fear of negative evaluation and self-esteem also had significant relations to shyness. A stepwise regression analysis indicated that fear of negative evaluation, self-esteem, and interpersonal rejection were significant predictors of shyness, and self-esteem was the best predictor. These results provided evidence of the role of distorted relationship beliefs, approval concerns, and self-evaluations in shyness for Turkish university students. The authors discuss the findings in terms of relevant literature and cultural issues.

Microbial diversity of western Canadian subsurface coal beds and methanogenic coal enrichment cultures

Coalbed methane is an unconventional fuel source associated with certain coal seams. Biogenic methane can comprise a significant portion of the gas found in coal seams, yet the role of microbes in methanogenesis in situ is uncertain. The purpose of this study was to detect and identify major bacterial and archaeal species associated with coal sampled from sub-bituminous methane-producing coal beds in western Canada, and to examine the potential for methane biogenesis from coal. Enrichment cultures of coal samples were established to determine how nutrient amendment influenced the microbial community and methane production in the laboratory. 16S rRNA gene clone libraries were constructed using DNA extracted and amplified from uncultured coal samples and from methanogenic coal enrichment cultures. Libraries were screened using restriction fragment length polymorphism, and representative clones were sequenced. Most (> 50%) of the bacterial sequences amplified from uncultured coal samples were affiliated with Proteobacteria that exhibit nitrate reduction, nitrogen fixation and/or hydrogen utilization activities, including Pseudomonas, Thauera and Acidovorax spp., whereas enrichment cultures were dominated by Bacteroidetes, Clostridia and/or Lactobacillales. Archaeal 16S rRNA genes could not be amplified from uncultured coal, suggesting that methanogens are present in coal below the detection levels of our methods. However, enrichment cultures established with coal inocula produced significant volumes of methane and the archaeal clone libraries were dominated by sequences closely affiliated with Methanosarcina spp. Enrichment cultures incubated with coal plus organic nutrients produced more methane than either nutrient or coal supplements alone, implying that competent methanogenic consortia exist in coal beds but that nutrient limitations restrict their activity in situ. This report adds to the scant literature on coal bed microbiology and suggests how microbes may be

Turkish electricity reform has progressed slowly due to internal resistance against privatisation, and gained momentum after Electricity Market Law of 2001, prepared in line with EU Energy Acquis and established required institutional and legal framework. Although the eligibility threshold has reached 39% market opening rate, the dominant position of public both as owner and decision-maker is still the major problem in the sector. Currently Turkey is self-sufficient in electricity, but likely to face shortages in 10 years if the growing demand is not met by either speeding the liberalisation process, or joining the South East Europe Electricity Market.

Miners inhaling respirable coal dust (CD) frequently develop coal workers' pneumoconiosis. Many coal miners are also exposed to polycyclic aromatic hydrocarbon (PAH) components of diesel engine exhaust and cigarette smoke, which may contribute to lung disease in these workers. Recently, apoptosis was reported to play a critical role in the development of another pneumoconiosis of miners, silicosis. In addition, CID was reported to suppress cytochrome P450 1A1 (CYP1A1) induction by PAHs. We exposed rats intratracheally to 0.0, 2.5, 10.0, 20.0, or 40.0 mg/rat CD and, 11 days later, to intraperitoneal P-naphthoflavone (BNF), a PAH. In another group of rats exposed to CD and BNF, caspase activity was inhibited by injection of the pan-caspase inhibitor Q-VD-OPH (quinoline-Val-Asp (OMe)-CH{sub 2}-OPH). In rats exposed to BNF, CD exposure increased alveolar expression of the proapoptotic mediator Bax but decreased CYP1A1 induction relative to BNF exposure alone. Pan-caspase inhibition decreased CD-associated Bax expression and apoptosis but did not restore CYP1A1 activity. Further, CD-induced lung inflammation and alveolar epithelial cell hypertrophy and hyperplasia were not suppressed by caspase inhibition. It is concluded that combined BNF and CD exposure increased Bax expression and apoptosis in the lung, but Bax and apoptosis were not the major determinants of early lung injury in this model.

According to the World Energy Council (WEC), at the beginning of the next century three main energy sources - coal, nuclear power and oil will have equal share in the world's total energy supply. This forecast is also valid for the USSR which possesses more than 40% of the world's coal resources and continuously increases its coal production (more than 700 million tons of coal are processed annually in the USSR). The stringent environmental regulations, coupled with the tendency to increase the use of coal are the reasons for developing different concepts for clean coal utilization. In this paper, the potential efficiency and environmental performance of different clean coal production cycles are considered, including technologies for coal clean-up at the pre-combustion stage, advanced clean combustion methods and flue gas cleaning systems. Integrated systems, such as combined gas-steam cycle and the pressurized fluidized bed boiler combined cycle, are also discussed. The Soviet National R and D program is studying new methods for coal utilization with high environmental performance. In this context, some basic research activities in the field of clean coal technology in the USSR are considered. Development of an efficient vortex combustor, a pressurized fluidized bed gasifier, advanced gas cleaning methods based on E-beam irradiation and plasma discharge, as well as new catalytic system, are are presented. In addition, implementation of technological innovations for retrofitting and re powering of existing power plants is discussed. (author)

Analyzes expansion of coal mixtures in coke ovens during coking. Methods for measuring coal expansion on both a laboratory and pilot plant scale are comparatively evaluated. The method, developed, tested and patented in Poland by the Institute for Chemical Coal Processing in Zabrze (Polish standard PN-73/G-04522), is discussed. A laboratory device developed by the Institute for measuring coal expansion is characterized. Expansion of black coal from 10 underground mines in the Ostrava-Karvina coal district and from 9 coal mines in the Upper Silesia basin in Poland is comparatively evaluated. Investigations show that coal expansion reaches a maximum for coal types with a volatile matter ranging from 20 to 25%. With increasing volatile matter in coal, its expansion decreases. Coal expansion increases with increasing swelling index. Coal expansion corresponds with coal dilatation. With increasing coal density its expansion increases. Coal mixtures should be selected in such a way that their expansion does not cause a pressure exceeding 40 MPa. 11 refs.

The existence of coal deposits in Venezuela has been known since the early nineteenth century, when the Naricual Mines were discovered in the State of Anzoategui Eastern Venezuela. Through the years the Venezuelan coal business had its ups and downs, but it was not until 1988 that we could properly say that our coal began to play a role in the international market. This paper reports that it is only now, in the nineties, that Venezuelan coal projects have come under a planning, promotional and developmental policy preparing the ground for the great projects Venezuela will have in the not-too-distant future

Although China owns large coal reserves, it now faces the problem of depletion of its coal resources in advance. The coal-based energy mix in China will not change in the short term, and a means of delaying the coal resources depletion is therefore urgently required. The residual coal was exploited first with a lower recovery percentage and was evaluated as commercially valuable damaged coal. This approach is in comparison to past evaluations when the residual coal was allocated as exploitation losses. Coal recovery rates, the calculation method of residual coal reserves and statistics of its mines in China were given. On this basis, a discussion concerning the impacts on the delay of China's coal depletion, development of coal exploitation and sustainable developments, as well as technologies and relevant policies, were presented. It is considered that the exploitation of residual coal can effectively delay China's coal depletion, inhibit the construction of new mines, redress the imbalance between supply and demand of coal in eastern China, improve the mining area environment and guarantee social stability. The Chinese government supports the exploitation technologies of residual coal. Hence, exploiting residual coal is of considerable importance in sustainable development of the coal industry in China. - Highlights: •Pay attention to residual coal under changing energy-mix environment in China. •Estimate residual coal reserves and investigate its exploitation mines. •Discuss impacts of residual coal exploitation on delay of coal depletion in China. •Discuss impacts on coal mining industry and residual coal exploitation technology. •Give corresponding policy prescriptions.

Three hundred and six coal samples were taken from main coal mines of twenty-six provinces, autonomous regions, and municipalities in China, according to the resource distribution and coal-forming periods as well as the coal ranks and coal yields. Nitrogen was determined by using the Kjeldahl method at U. S. Geological Survey (USGS), which exhibit a normal frequency distribution. The nitrogen contents of over 90% Chinese coal vary from 0.52% to 1.41% and the average nitrogen content is recommended to be 0.98%. Nitrogen in coal exists primarily in organic form. There is a slight positive relationship between nitrogen content and coal ranking. ?? 2011 Science Press, Institute of Geochemistry, CAS and Springer Berlin Heidelberg.

Trust and safety in the coal mining sector

This report examines the relationship between trust (and mistrust) and occupational health and safety (OHS) in the Australian coal mining sector. Previous research in Australian coal mining companies indicated that mistrust is deep-seated at a number of mines, and that these mines are usually the worst performers in terms of OHS. Mistrust also handicaps the ability of inspectors to worker together with mines sites to improve OHS outcomes. Given this, there is a compelling need to understand how mistrust comes about, and to identify practical steps that can be adopted by companies, mines sites and the inspectorate to foster the development of trust. The report builds on these earlier findings by investigating trust in a much more detailed and sophisticated fashion, drawing on an in-depth analysis at mines, across a number of coal mining companies, and in two state jurisdictions. Research revealed that a 'cluster of characteristics' are associated with the formation and maintenance of mistrust at mines with a lower OHS track-record. These findings, together with an analysis of the characteristics of mines with better OHS outcomes, enabled the report to outline a variety of ways in which mines may build trust within and between management and the workforce. It also considers the at times fractious relationship between trade unions and management, and flags some of the challenges confronting these two groups in working together to improve OHS performance in the coal mining sector. Finally, the report examines the rise and impact of mistrust on the operations of the New South Wales and Queensland inspectorates, and suggests ways in which a fairer and more just enforcement policy may help foster greater trust between inspectors and mines.

In recent decades, China has encountered serious environmental problem, especially severe air pollution that has affected eastern and northern China frequently. Because most air pollutants in China are closely related to coal combustion, the restriction of coal consumption is critical to the improvement of the environment in China. In this study, a panel of 29 Chinese provinces from 1995 to 2012 is utilized to predict China’s coal consumption through 2020. After controlling for the spatial correlation of coal consumption among neighboring provinces, an inverted U-shaped Environmental Kuznets Curve (EKC) between coal consumption per capita and GDP per capita in China is detected. Furthermore, based on the estimation results and reasonable predictions of key control variables, China’s provincial and national coal consumption through 2020 is forecasted. Specifically, under the benchmark scenario, consumption is expected to continue growing at a decreasing rate until 2020, when China’s coal consumption would be approximately 4.43 billion tons. However, if China can maintain relatively high growth rate (an annual growth rate of 7.8 percent), the turning point in total coal consumption would occur in 2019, with projected consumption peaking at 4.16 billion tons. - Highlights: • Provincial panel data is used to investigate the influential factors of coal consumption in China. • The spatial correlations of coal consumption in neighboring provinces are fully considered. • An inverted-U shaped Environmental Kuznets Curve for coal consumption in China has been found. • Based on the estimation results, China’s national coal consumption before 2020 is forecasted. • Under the basic scenario, China’s national coal consumption will grow at a decreasing speed till 2020.

Coal in competition

Manners, G

1985-06-01

During the past decade world coal consumption has expanded by about 26% whilst energy demands overall have grown by only 17%. This is because of the increased price of oil products, plus a period during which the costs of mining coal in many parts of the world have been moderately well contained. Over-ambitious forecasts of coal demand have encouraged the considerable over-investment in coalmining capacity that exists today. Costs of winning coal and transporting it are low, but sales depend on the rate of growth of a country's demand for energy. Some countries are more successful at marketing coal than others. Amongst the major factors that influence the rate of substitution of one source of energy for another is the nature and age of the boiler stock. The outcome of the developing environmental debate and calls for reduction in SO/sub 2/ and NO/sub x/ emissions from coal-fired boilers is going to affect coal's fortunes in the 1990's.

In a mine area, some environment geotechnics problems always occure, induced by mined-out region such as the subsidence and cracks at ground level, deformation and destruction of buildings, landslides destruction of water resources and the ecological environment. In order to research the migration of surrounding rock and coal in steeply inclined super high seams which used fully mechanized top coal caving, a working face of a certain mine was made as an example, analyzed the migration law of the overlay rock and coal under different caving ratio of fully mechanized top coal caving with numerical simulation analysis. The results suggest that the laws of overlay rock deformation caused by deeply inclined coal seam were different from horizontal coal seam. On the inclined direction, with an increase of dip angle and caving ratio, the vertical displacement of overlay rock and coal became greater, the asymmetric phenomenon of vertical displacement became obvious. On the trend direction, active region and transition region in goaf became smaller along with the increase of mining and caving ratio. On the contrary, the stable region area became greater. Therefore, there was an essential difference between the mechanism of surface movement deformation with deeply inclined coal seam and that with horizontal coal seam.

Suicidal behavior and its variation across social contexts are of importance for the science of suicidology. Due to its special character controlled experimental studies on suicide are ruled out for ethical reasons. Cross-cultural studies may throw light on the etiology of both suicidal behavior and its cross-cultural variation. The present study compared suicidal behavior and attitudes in 423 Slovak and 541 Turkish high school students by means of a self-report questionnaire. The two groups reported similar percentages (Slovak = 36.4%; Turkish = 33.8%) of lifetime, past 12-months or current suicidal ideation but significantly more Turkish (12.2%) than Slovak (4.8%) students reported lifetime or past 12-months suicide attempts. Slovak adolescents displayed more liberal and permissive attitudes toward suicide, while those of Turkish adolescents were more rejecting. Turkish students rated themselves to be more religious and hence they believed to a greater extent that suicidal persons would be punished in a life after death than their Slovak peers. However, attitudes of Turkish students toward an imagined suicidal close friend were more accepting than the attitudes of Slovak students. Comparison of suicidal and nonsuicidal students revealed that those reporting suicidal ideation or attempts were more accepting of suicide and viewed suicide as a solution to a greater extent than the nonsuicidal ones. The results from this study suggest that cultural factors play a role in suicidal behavior, attitudes and reactions in a predicted direction.

The aim of this study was to evaluate the reliability and validity of the Turkish version of the Internalized Stigma of Mental Illness Scale (ISMI) in patients with psychiatric disorders. The study included 203 patients diagnosed with various psychiatric disorders in a psychiatry outpatient clinic of a university hospital. The reliability of the scale was assessed by investigation of its internal consistency and split-half reliability. The convergent validity of the scale was demonstrated by the relationship between the Turkish form of the ISMI and various criteria scales. Cronbach's alpha value was 0.93 for the entire scale and ranged between 0.63 and 0.87 for the 5 subscales of the ISMI. In terms of convergent validity, the total score of the Turkish ISMI significantly correlated with the Beck Depression Inventory, Rosenberg Self-Esteem Scale, Sociotropy-Autonomy Scale, Brief Symptom Inventory, Multidimensional Scale of Perceived Social Support, Clinical Global Impression Scale, and Global Assessment of Functioning Scale scores. All values were in the expected direction. In the light of the findings, it was concluded that the Turkish version of ISMI could be used as a reliable and valid tool in assessing internalized stigma of the Turkish psychiatric patients.

Full Text Available Turkish teachers’ attitudes towards reading habit have an important influence on their students in acquiring reading habit. Thus, the variables affecting the in-service and preservice Turkish teachers’ attitudes towards reading must be investigated. The purpose of this study is to determine if pre-service Turkish teachers’ attitudes towards reading habit show difference depending on various variables. The data were gathered from, 1st, 2nd, 3rd, and 4th graders studying at the Department of Turkish Education in Gazi Education Faculty at Gazi University. Likert type attitude scale was used for gathering data in this research. Independent-Samples T-test, Scheffe Test, One Way ANOVA are used for analyzing the data. The findings of the research assert that pre-service Turkish teachers’ attitudes towards reading habit are influenced by gender, reading frequency, and whether they read periodicals. In this study it is proposed that students at all grades of education must be given activities which have positive influence on attitudes towards reading habits. And, also, the school libraries and public libraries must be arranged to support positive attitudes through reading habits.

Acidithiobacillus ferrooxidans (A. ferrooxidans) was applied in coal biodesulfurization and coal's pyrite bioleaching. The result showed that A. ferrooxidans had significantly promoted the biodesulfurization of coal and bioleaching of coal's pyrite. After 16 days of processing, the total sulfur removal rate of coal was 50.6%, and among them the removal of pyritic sulfur was up to 69.9%. On the contrary, after 12 days of processing, the coal's pyrite bioleaching rate was 72.0%. SEM micrographs showed that the major pyrite forms in coal were massive and veinlets. It seems that the bacteria took priority to remove the massive pyrite. The sulfur relative contents analysis from XANES showed that the elemental sulfur (28.32%) and jarosite (18.99%) were accumulated in the biotreated residual coal. However, XRD and XANES spectra of residual pyrite indicated that the sulfur components were mainly composed of pyrite (49.34%) and elemental sulfur (50.72%) but no other sulfur contents were detected. Based on the present results, we speculated that the pyrite forms in coal might affect sulfur biooxidation process. PMID:24288464

The attitudes of veterinary faculty toward animal welfare were surveyed in four Australian and three Turkish veterinary schools. The former were considered to be typical of modern Western schools, with a faculty of more than 40% women and a primary focus on companion animals, whereas the latter were considered to represent more traditional veterinary teaching establishments, with a faculty of 88% men and a primary focus on livestock. A total of 116 faculty responded to the survey (42 Australian and 74 Turkish faculty members), for response rates of 30% and 33%, respectively. This survey included demographic questions as well as questions about attitudes toward animal-welfare issues. Women were more concerned than men about animal-welfare issues, especially the use of animals in experiments, zoos, entertainment, and sports and for food and clothing. Total scores demonstrated different concerns among Turkish and Australian faculty. The study demonstrates that the veterinary faculty of these two countries have different concerns for animal welfare, concerns that should be acknowledged in considering the welfare attitudes that students may adopt.

Full Text Available Beef consumption has significantly increased in the last fifty years as a response to the increase in population size, whereas the sustainability of production systems has begun to be questioned. Because the residues left in the animal feed additives used in conventional food production constitute major health problems in consumers. Therefore, an interest in organic farming methods based on natural grazing and feed production without the use of chemicals is increasing. One of the most important examples of organic beef production in Turkey is the project carried out in the villages of Ayvacık district in Çanakkale. This region has an ecological structure which does not allow an extensive production of culture cattle. The most important advantages of the Turkish grey cattle living in the pastures in the region covered with bushes are that they have less needs of shelter, they do not need supplementary feeding throughout the year and labor costs for their production for beef are low. Breeders in this region maintained a market price for their products by shifting to organic system and thus allowed the sustainable production of the Turkish grey cattle. In this study, Ayvacık Organic Beef Production Project which sets an example for the sustainability of Turkish grey cattle production by featuring its surplus values was evaluated.
