Wootz: Erroneous Transliteration of Sanskrit " Utsa" used for Indian Crucible Steel
Dube, R. K.
2014-11-01
The terminology Wootz for the legendary Indian crucible steel was first introduced by Helenus Scott in his letter to Joseph Banks, the then President of the Royal Society, London, in 1794. He stated several salient features of this steel in his letter. During the period 1794-1796, Banks received approximately 200 lbs. of this steel from Scott. Banks assigned several professionals to carry out experimental work on Indian crucible steel. One such important person was the famous surgical instrument maker, cutler and metallurgist of his time, James Stodart. Stodart experimented extensively with the Indian crucible steel, and was its great admirer. It has been shown, along with corroborative documentary evidence, that the original word for this steel was Sanskrit word " utsa". This was erroneously transliterated in Roman script as Wootz by Scott in his letter to Banks. It was James Stodart, who preserved the Sanskrit word " utsa" written in Devanāgarī script on his trade card for future generation. The reason for using this word for the Indian crucible steel has also been discussed.

The Indian power sector will face numerous challenges over the next four decades. More than one third of India's population currently do not have access to electricity. Urgent action is needed to overcome this problem of energy poverty. At the same time rapid economic growth is projected to increase electricity demand by fivefold to sixfold between now and 2050. Massive investments will be needed to meet this increased demand, but this will also create unique opportunities to transform the power sector towards a low-carbon future. This Information Paper presents in more detail the analysis for India published in Energy Technology Perspectives 2010. The paper investigates the best way of achieving deep CO2 emission cuts in the Indian power system while allowing the Indian economy to continue growing and meeting the challenge of alleviating energy poverty. It does so from a techno-economic perspective - building on detailed resource and technology data for India - and identifies the key power sector technologies needed for India to realise such a transition.

Highlights: • India specific RAFM steel IN-RAFM has been produced in commercial scale and physical property data for the same have been generated. • Mechanical properties of the commercial heats are comparable to that of the laboratory heats. • IN-RAFM steel filler wires has been produced indigenously. • Process parameters have been optimized so that toughness of the fusion zone of the EB and laser welds is comparable to that of the base metal even at sub-zero temperatures. • Fabrication of the mock ups of different components of Indian TBM has been initiated. - Abstract: India has indigenously developed its own Indian Reduced Activation Ferritic Martensitic Steel (IN-RAFM steel) which, it is proposed to use for fabrication of Indian TBM to be installed in ITER. With an objective of qualifying this material for use in ITER, extensive testing of this material to generate the necessary data required to offer this material for Particular Material Appraisal of ITER has been undertaken. Accordingly, data generation on creep, fatigue and physical properties of this steel is in progress. Physical properties like thermal diffusivity, heat capacity and thermal expansion coefficient for this steel at various temperatures have been measured and thermal conductivity estimated from the measured physical properties. Values obtained for these physical properties are comparable with those reported for other RAFM steels. Results of creep tests that are in progress also indicate that creep is comparable to that of other RAFM steels. Low cycle fatigue (LCF) behaviour of this steel has been studied in air with total strain control in the strain amplitude range of ±0.25–1% and temperatures range of 300–873 K at a constant strain rate of 3 × 10{sup −3} s{sup −1}. Results confirm that fatigue life of IN-RAFM steel is at par with that of the European Union grade Eurofer 97 RAFM steel.

Smyth, Russell; Narayan, Paresh Kumar; Shi, Hongliang
2011-01-01
China's steel sector is the largest in the world and has been a major driving force behind China's high rate of economic growth. This sector, however, is also a major consumer of energy and, in particular, coal. As a result, the iron and steel sector in China is a major contributor to greenhouse gas emissions and other pollutants. In this article we examine the potential for inter-factor substitution between capital, energy and labor in the Chinese steel sector and find that capital and energy and energy and labor are substitutes. This result suggests that removal of price ceilings on energy would tend to reduce energy use and increase capital intensiveness. While the potential for substitution between energy and labor is less than that between energy and capital, the elasticity of substitution between energy and labor is high compared with previous findings for other countries. This fact suggests that there may be potential for substituting labor for energy, given China's abundance of labor.

This study develops and examines physical energy intensity indicators in five industrial sub-sectors-iron and steel, aluminum, textiles, paper, and cement-and investigates mitigation options for energy related CO 2 emissions (during 1991-2005). Decomposition analysis has been employed to separate the structural effect (share of different products in the sector) from pure intensity effect (efficiency increase through technical improvement) for each industry. The results show that the combined effect (considering both structural and intensity effects together) on both iron and steel and paper and pulp industries is negative while it is positive for aluminum and textiles. The intensity effect for all the industries, barring textiles, is negative showing improvement in energy efficiency; iron and steel in particular, has seen a decrease of 134 PJ in energy consumption owing to improvements in efficiency. However, energy intensity in textiles has risen by 47 PJ due to increased mechanization. Structural effect is positive in aluminum and iron and steel industries indicating a movement towards higher energy-intensive products. In the case of aluminum, positive structural effect dominates over negative intensive effect whereas negative intensive effect dominates iron and steel industry. The paper helps in designing policies for improving productivity and reduce energy consumption in India's manufacturing sector. - Highlights: → The study develops physical energy intensity indicators in industrial sub-sectors of India. → It identifies technological and other options for reduction in energy consumption. → The study quantifies savings in energy as well as CO 2 emissions. → The indicators are useful in examining structural changes.

Highlights: • Chemical compatibility between Li_2TiO_3 and Indian RAFM steel has been studied at ITER operating temperature. • The lithium titanate chemically reacted with ferritic martensitic steel to form a brittle and non-adherent oxide layer. • The layer grew in a parabolic manner as a function of heating time. • Diffusion of oxygen (from Li_2TiO_3) appears to be controlling the oxide layer. - Abstract: Chemical compatibility between lithium titanate and Indian reduced activation ferritic-martensitic steel (In-RAFMS) was studied for the first time under ITER operating temperature. Lithium titanate required for the study was synthesized in-house. Coupons of In-RAFMS were packed inside lithium titanate powder and heated at 550 °C up to 900 h under inert argon atmosphere. The lithium titanate chemically reacted with ferritic martensitic steel to form a brittle and non-adherent oxide layer. The layer grew in a parabolic manner as a function of heating time. Microstructural and phase evolution of this oxide layer was studied using XRD, SEM and EPMA. Iron and chromium enriched zones were found within the oxide layer. Diffusion of oxygen (from Li_2TiO_3) appears to be controlling the oxide layer.

It is imperative to tackle the issue globally mobilizing all available policies and measures. One of the important ones among them is technology transfer and diffusion. By utilizing international co-operation, industry can promote such measures in two ways: through government policy and through industry's own voluntary initiative. Needless to say, various government policies and measures play essential role. By the same token, industry initiative can complement them. There is much literature documenting the former. On the contrary there are few on the latter. This paper sheds light on the latter. The purpose of this paper is to explore the effectiveness of global voluntary sectoral approach for technology diffusion and transfer based on steel sector experience. The goal is to contribute toward building a worldwide low-carbon society by manufacturing goods with less energy through international cooperation of each sector. The authors believe that the voluntary sectoral approach is an effective method with political and practical feasibilities, and hope to see the continued growth of more initiatives based on this approach. - Highlights: → There exist huge reduction potentials in steel industries globally. → Technology transfer and diffusion are keys to achieve reductions. → Main barriers are economic, technological and policy-related. → Case studies in overcoming barriers are discussed. → In steel industry, a voluntary sectoral approach has shown to be effective.

The study examines the dynamics of carbon emissions baselines of electricity generation in Indian states and Chinese provinces in the backdrop of ongoing electricity sector reforms in these countries. Two Indian states-Gujarat and Andhra Pradesh, and three Chinese provinces-Guangdong, Liaoning and Hubei have been chosen for detailed analysis to bring out regional variations that are not captured in aggregate country studies. The study finds that fuel mix is the main driver behind the trends exhibited by the carbon baselines in these five cases. The cases confirm that opportunities exist in the Indian and Chinese electricity sectors to lower carbon intensity mainly in the substitution of other fuels for coal and, to a lesser extent, adoption of more efficient and advanced coal-fired generation technology. Overall, the findings suggest that the electricity sectors in India and China are becoming friendlier to the global environment. Disaggregated analysis, detailed and careful industry analysis is essential to establishing a power sector carbon emissions baseline as a reference for CDM crediting. However, considering all the difficulties associated with the baseline issue, our case studies demonstrate that there is merit in examining alternate approaches that rely on more aggregated baselines

This paper assesses the impacts on the cement, steel and oil refining sectors in Spain of the carbon prices derived from the European Emissions Trading Scheme (EU ETS), and the potential effect on these sectors of the European Union anti-leakage policy measures. The assessment is carried out by means of three engineering models developed for this purpose. Our results show a high exposure to leakage of cement in coastal regions; a smaller risk in the steel sector, and non-negligible risk of leakage for the oil refining sector when carbon allowance prices reach high levels. We also find that the risk of leakage could be better handled with other anti-leakage policies than those currently in place in the EU. - Highlights: • We simulate the impact of carbon prices on the risk of leakage in the cement, steel and oil refining sectors. • We also assess the effectiveness of different anti-leakage policies in Europe. • Cement production in coastal areas is highly exposed. • The risk of leakage for steel and oil refining is smaller. • Anti-leakage policies should be modified to be efficient

Restructuring has changed the traditional mission and mandates of power utilities in complex ways, and had large impacts on environmental, social, and political conditions for any particular country. At the same time, new regulatory approaches are being found for reducing environmental impacts in restructured power sectors. India has a vast supply of renewable energy resources, and it has one of the largest programs in the world for deploying renewable energy based products and systems. So this paper attempts to review the various policies and measures undertaken by Indian government for promotion of renewable energy. The aim of this paper is also to review the current policy mechanisms, especially investment- or generation-based price-driven and capacity-driven mechanisms, ranging from investment incentives for the development of renewable energy projects, feed-in tariffs, production tax incentives, tradable green certificates, and their effects upon the prospects of encouraging as well as expanding the development of renewable energy in Indian restructured power sector. This will make renewable more attractive in the Indian future electricity market. (author)

Highlights: •Associated water impacts of individual energy conservation measures were evaluated. •Water-energy tradeoffs exist in the production process adjustment of iron sector. •Considering the water impacts can change the priority ranks of technology choice. -- Abstract: Moving towards integrated governance of water and energy requires balancing tradeoffs and taking advantage of synergies through specific technology choice. However, the water-energy conservation relationships of individual conservation measures in industries other than the water and energy sectors have not been investigated in detail. This study develops a hybrid model to estimate the associated water impacts of individual energy conservation measures, using China’s iron and steel industry as a case study. The results reveal that water-energy tradeoffs exist in the production process adjustment, which is conventionally promoted as a key energy-saving measure in iron and steel industry. It is found that replacing the Blast Oxygen Furnace (BOF) process with the Electric Arc Furnace (EAF) in 2007 could save 131–156 kg coal equivalent (kgce) (13.2–15.7%) of embodied energy per ton of crude steel (tcs) at the expenses of an additional 2.5–3.9 m 3 /tcs (10.6–16.4%) of water footprint. Nineteen energy efficiency technologies are studied in this research, and most of them are identified as having water-saving synergies except for the Low Temperature Rolling Technology. Taking these water impacts into consideration can update the priority ranks of the technology choices and inform policy decisions. Although this study focuses on China’s iron and steel sector, the methods and analysis can be extended to other countries, sectors, technologies and environmental impacts.

The goal of the modeling work carried out in this project was to quantify long-term scenarios for the future emission reduction potentials in the iron and steel sector. The main focus of the project is to examine the impacts of carbon reduction options in the U.S. iron and steel sector under a set of selected scenarios. In order to advance the understanding of carbon emission reduction potential on the national and global scales, and to evaluate the regional impacts of potential U.S. mitigation strategies (e.g., commodity and carbon trading), we also included and examined the carbon reduction scenarios in China’s and India’s iron and steel sectors in this project. For this purpose, a new bottom-up energy modeling framework, the Industrial Sector Energy Efficiency Modeling (ISEEM), (Karali et al. 2012) was used to provide detailed annual projections starting from 2010 through 2050. We used the ISEEM modeling framework to carry out detailed analysis, on a country-by-country basis, for the U.S., China’s, and India’s iron and steel sectors. The ISEEM model applicable to iron and steel section, called ISEEM-IS, is developed to estimate and evaluate carbon emissions scenarios under several alternative mitigation options - including policies (e.g., carbon caps), commodity trading, and carbon trading. The projections will help us to better understand emission reduction potentials with technological and economic implications. The database for input of ISEEM-IS model consists of data and information compiled from various resources such as World Steel Association (WSA), the U.S. Geological Survey (USGS), China Steel Year Books, India Bureau of Mines (IBM), Energy Information Administration (EIA), and recent LBNL studies on bottom-up techno-economic analysis of energy efficiency measures in the iron and steel sector of the U.S., China, and India, including long-term steel production in China.

Telemedicine is the use of communication networks to exchange medical information for providing healthcare services and medical education from one site to another. The application of telemedicine is more promising in economically developing countries with agrarian societies. The American Telemedicine Association (ATA) identifies three healthcare services: clinical medical services, health and medical education, and consumer health information. However, it is not clear how these services can be adopted by different sectors: public and private. This paper looks at four Indian case studies, two each in public and private sectors to understand two research questions: Are there differences in telemedicine adoption between public and private hospitals. If there are differences: What are the differences in telemedicine adoption between public and private sectors? Authors have used the extant literature in telemedicine and healthcare to frame theoretical background, describe the research setting, present the case studies, and provide discussion and conclusions about their findings. Authors believe that as India continues to develop its telemedicine infrastructures, especially with continued government support through subsidies to private telemedicine initiatives, its upward trend in healthcare will continue. This is expected to put India on the path to increase its life expectancy rates, especially for it rural community which constitute over 70% of its populace.

Full Text Available This paper examines CO2 emissions from electricity and fuel consumption of different energy sources consumed in the Iron and Steel Industry sector (non-ferrous included, also known as basic metal in five South Asian countries including Bangladesh, India, Nepal, Sri Lanka and Pakistan. The study finds that about 30% of the total energy in the manufacturing industry is used in this sector, which is about 11% of total industrial input, contributing approximately 13% to the Manufacturing Value Added (MVA. Electricity, on the other hand, shares almost 60% of total energy consumption in the five countries in South Asia, followed by natural gas, coal, kerosene and diesel. The study also finds that CO2 emissions vary across sectors in countries in which the study was conducted. For instance, while in Bangladesh CO2 emissions are primarily caused by electricity generation, in India the majority of CO2 emissions are originated from coal. On the contrary, CO2 emissions in Nepal are mostly generated through other fuels such as Charcoal, Diesel and Kerosene. This study provides some policy recommendations, which could help reduce CO2 emissions in the Iron and Steel Industry sector in the South Asian region.

The Southern Ocean (SO) is one of the important regions where significant processes and feedbacks of the Earth's climate take place. Expeditions to the SO provide useful data for improving global weather/climate simulations and understanding many processes. Some of the uncertainties in these weather/climate models arise during the first few days of simulation/forecast and do not grow much further. NCMRWF issued real-time five day weather forecasts of mean sea level pressure, surface winds, winds at 500 hPa & 850 hPa and rainfall, daily to NCAOR to provide guidance for their expedition to Indian sector of SO during the austral summer of 2014-2015. Evaluation of the skill of these forecasts indicates possible error growth in the atmospheric model at shorter time scales. The error growth is assessed using the model analysis/reanalysis, satellite data and observations made during the expedition. The observed variability of sub-seasonal rainfall associated with mid-latitude systems is seen to exhibit eastward propagations and are well reproduced in the model forecasts. All cyclonic disturbances including the sub-polar lows and tropical cyclones that occurred during this period were well captured in the model forecasts. Overall, this model performs reasonably well over the Indian sector of the SO in medium range time scale.

Full Text Available On the basis of the Volume Correlation Model (VCM as well as data on steel consumption and scrap collection per industry sector (construction, automotive, industrial goods, and consumer goods, it was possible to estimate service lifetimes of steel in the United States between 1900 and 2016. Input data on scrap collection per industry sector was based on a scrap survey conducted by the World Steel Association for a static year in 2014 in the United States. The lifetimes of steel calculated with the VCM method were within the range of previously reported measured lifetimes of products and applications for all industry sectors. Scrapped (and apparent lifetimes of steel compared with measured lifetimes were calculated to be as follows: a scrapped lifetime of 29 years for the construction sector (apparent lifetime: 52 years compared with 44 years measured in 2014. Industrial goods: 16 (27 years compared with 19 years measured in 2010. Consumer goods: 12 (14 years compared with 13 years measured in 2014. Automotive sector: 14 (19 years compared with 17 years measured in 2011. Results show that the VCM can estimate reasonable values of scrap collection and availability per industry sector over time.

This paper approaches the measurement of energy efficiency from a production theoretic framework and uses Data Envelopment Analysis to measure energy efficiency in the Indian manufacturing sector. Using data from the Annual Survey of Industries for the years 1998-99 through 2003-04, the study compares the energy efficiency in manufacturing across states, based on several models. The results show considerable variation in energy efficiency across states. Comparing the results across our models, we find that the relative pricing of energy does not provide the appropriate incentives for energy conservation. A second-stage regression analysis reveals that states with a larger share of manufacturing output in energy-intensive industries have lower energy efficiency. Also, higher quality labor force associates with higher energy efficiency. Finally, the power sector reforms have not yet had any significant impact on achieving energy efficiency

India's Universal Immunization Programme (UIP) provides basic vaccines free-of-cost in the public sector, yet national vaccination coverage is poor. The Government of India has urged an expanded role for the private sector to help achieve universal immunization coverage. We conducted a state-by-state analysis of the role of the private sector in vaccinating Indian children against each of the six primary childhood diseases covered under India's UIP. We analyzed IMS Health data on Indian private-sector vaccine sales, 2011 Indian Census data and national household surveys (DHS/NFHS 2005-06 and UNICEF CES 2009) to estimate the percentage of vaccinated children among the 2009-12 birth cohort who received a given vaccine in the private sector in 16 Indian states. We also analyzed the estimated private-sector vaccine shares as function of state-specific socio-economic status. Overall in 16 states, the private sector contributed 4.7% towards tuberculosis (Bacillus Calmette-Guérin (BCG)), 3.5% towards measles, 2.3% towards diphtheria-pertussis-tetanus (DPT3) and 7.6% towards polio (OPV3) overall (both public and private sectors) vaccination coverage. Certain low income states (Uttar Pradesh, Rajasthan, Madhya Pradesh, Orissa, Assam and Bihar) have low private as well as public sector vaccination coverage. The private sector's role has been limited primarily to the high income states as opposed to these low income states where the majority of Indian children live. Urban areas with good access to the private sector and the ability to pay increases the Indian population's willingness to access private-sector vaccination services. In India, the public sector offers vaccination services to the majority of the population but the private sector should not be neglected as it could potentially improve overall vaccination coverage. The government could train and incentivize a wider range of private-sector health professionals to help deliver the vaccines, especially in the low

Highlights: • Use ISEEM to evaluate energy and emission reduction in U.S. Iron and Steel sector. • ISEEM is a new bottom-up optimization model for industry sector energy planning. • Energy and emission reduction includes efficiency measure and international trading. • International trading includes commodity and carbon among U.S., China and India. • Project annual energy use, CO 2 emissions, production, and costs from 2010 to 2050. - Abstract: Using the ISEEM modeling framework, we analyzed the roles of energy efficiency measures, steel commodity and international carbon trading in achieving specific CO 2 emission reduction targets in the U.S iron and steel sector from 2010 to 2050. We modeled how steel demand is balanced under three alternative emission reduction scenarios designed to include national energy efficiency measures, commodity trading, and international carbon trading as key instruments to meet a particular emission restriction target in the U.S. iron and steel sector; and how production, process structure, energy supply, and system costs change with those scenarios. The results advance our understanding of long-term impacts of different energy policy options designed to reduce energy consumption and CO 2 emissions for U.S. iron and steel sector, and generate insight of policy implications for the sector’s environmentally and economically sustainable development. The alternative scenarios associated with 20% emission-reduction target are projected to result in approximately 11–19% annual energy reduction in the medium term (i.e., 2030) and 9–20% annual energy reduction in the long term (i.e., 2050) compared to the Base scenario

Full Text Available Public expenditure on healthcare in India is low by international comparison, and access to essential treatment pushes many uninsured citizens below the poverty line. In many countries, policymakers utilize health technology assessment (HTA methodologies to direct investments in healthcare, to obtain the maximum benefit for the population as a whole. With rising incomes and a commitment from the Government of India to increase the proportion of gross domestic product spent on health, this is an opportune moment to consider how HTA might help to allocate healthcare spending in India, in an equitable and efficient manner. Despite the predominance of out-of-pocket payments in the Indian healthcare sector, payers of all types are increasingly demanding value for money from expenditure on healthcare. In this review we demonstrate how HTA can be used to inform several aspects of healthcare provision. Areas in which HTA could be applied in the Indian context include, drug pricing, development of clinical practice guidelines, and prioritizing interventions that represent the greatest value within a limited budget. To illustrate the potential benefits of using the HTA approach, we present an example from a mature HTA market (Canada that demonstrates how a new treatment for patients with atrial fibrillation - although more expensive than the current standard of care - improves clinical outcomes and represents a cost-effective use of public health resources. If aligned with the prevailing cultural and ethical considerations, and with the necessary investment in expert staff and resources, HTA promises to be a valuable tool for development of the Indian healthcare sector.

All the growth-oriented sectors in a developing economy consume enormous energy in their production processes. Steel, aluminium and cement are the key manufacturing industries in India which provide inputs to various other sectors such as construction, transportation, power transmission, etc. As a result, their demand is consistently rising. These industries are heavily energy-intensive and use raw materials such as iron ore, coal, electricity, steam, and fuel oil, whose supply can act as severe production constraints over a period of time and can hinder sustainable development. Hence it becomes imperative for these industries to continuously innovate more energy efficient techniques. This paper makes a foray into the energy demand for these industries and explores the potential of any future reduction in their energy consumption. The paper offers a projection scenario for 2001-2031 (based on the MARKAL Modeling exercise for India) for possible catching up in reduction in energy consumptions in these sectors under alternative situations. The analysis suggests the existence of some plausible energy efficiency enhancing techniques in these industries. Exploring these options will definitely ensure cost effectiveness and competitiveness of these three key sectors in the global market. -- Research highlights: →Energy reduction potential exists in Indian steel, aluminium and cement sectors and can go up to 8%, 17% and 6% respectively in these sectors in 2031 if appropriate energy saving technologies are introduced and implemented. →In aluminium industry energy reduction potential is huge in fabrication stage in the production process and extensive improvement can be done in terms of energy efficiency in this stage. Cogeneration of power through waste heat recovery, change in norms in standard to take advantage of producing composite cements using more than one industrial waste, like both fly ash and slag are important required changes in Indian cement sector.

The Indian Government is currently thinking of allowing private sector to participate in power sector inviting private sector to generate electricity mainly from coal. The main motivation is resource mobilization from private sector, since the Plan funds are diverted to rural development away from power sector; and yet the massive expansion has to be financed. The paper analyzes the inherent difficulties and contradictions in the Government's proposal, such as co-existence of high cost private power and low cost public power, the potential goal-conflicts of private and public utilities and the constraints in raising finance. It suggests a different model in order to make the privatization proposition feasible. 12 refs

The dairy sector is known to have significant local and global environmental impacts; but it also has proven renewable-energy generation potential. This paper analyzes a specific niche experiment in the Indian dairy industry, wherein cattle waste management is carried out by a multitude of stakeholders. These include the waste collectors, local technology adopters, research institutions, multilateral donor agencies, the Indian government, technology suppliers and operation and maintenance teams who have managed an uninterrupted 1 MWe energy production over the past 4 years. This analysis uses the sociotechnical regime framework to study the interaction of social, technological, economic and policy-related aspects relevant to the niche experiment. The analysis shows a potential to contribute to the development of two complementing regimes-one related to cooperative waste management and the other related to grid-connected renewable-energy-based electricity generation. Key factors for a successful development are not only a long-term financing protection through government subsidies to cover higher capital cost and a preferential tariff related to energy throughput, but also the adaptation of technology, the embedding in the local cooperative structure and the removal of regulatory barriers.

The introduction of new technologies, which can support and empower human capabilities in a number of professional tasks while possibly reducing the need for cumbersome operations and the exposure to risk and professional diseases, is nowadays perceived as a must in any industrial field, process industry included. However, despite their relevant potentials, new technologies are not always easy to introduce in the professional environment. A design procedure which takes into account the workers' acceptance, needing and capabilities as well as a continuing education and training process of the personnel who must exploit the innovation, is as fundamental as the technical reliability for the successful introduction of any new technology in a professional environment. An exemplary case is provided by symbiotic human-robot-cooperation. In the steel sector, the difficulties for the implementation of symbiotic human-robot-cooperation is bigger with respect to the manufacturing sector, due to the environmental conditions, which in some cases are not favorable to robots. On the other hand, the opportunities and potential advantages are also greater, as robots could replace human operators in repetitive, heavy tasks, by improving workers' health and safety. The present paper provides an example of the potential and opportunities of human-robot interaction and discusses how this approach can be included in a social innovation paradigm. Moreover, an example will be provided of an ongoing project funded by the Research Fund for Coal and Steel, "ROBOHARSH", which aims at implementing such approach in the steel industry, in order to develop a very sensitive task, i.e. the replacement of the refractory components of the ladle sliding gate.

Industrial energy efficiency is of paramount importance both for conserving energy resources and reducing CO 2 emissions. In this paper, we compare specific energy consumption among countries in fossil power generation, steel, and cement sectors. The evaluations were conducted using common system boundaries, allocation, and calculation methods. In addition, we disaggregate within sectors, such as with blast furnace–basic oxygen furnace (BF–BOF) steel and scrap-based electric arc furnace (Scrap-EAF) steel. The results reveal that characteristics vary by sub-sector. Regional differences in specific energy consumption are relatively large in the power, BF–BOF steel, and cement sectors. For coal power generation and BF–BOF steel production, continual maintenance and rehabilitation are of key importance. We confirm these key factors identified in the previous work on our estimated numerical values. In BF–BOF steel production, corrections for hot metal ratios (pig iron production per unit of BOF crude steel production) and quality of raw materials have a large effect on the apparent specific energy consumption. Available data is not yet sufficient for straightforward evaluation of the steel and cement sectors. - Highlights: ► We compare energy efficiency among countries in power, steel, and cement sectors. ► In steel and cement sectors, the results are provided in terms of specific energy consumption (GJ/ton of product). ► We distinguish BOF steel and EAF steel. ► New installation and continual maintenance are the key for energy efficiency. ► Corrections have a large impact on apparent specific energy consumption.

Quantifying the Impacts of Large Scale Integration of Renewables in Indian Power Sector
Kumar, P.; Mishra, T.; Banerjee, R.
2017-12-01
India's power sector is responsible for nearly 37 percent of India's greenhouse gas emissions. For a fast emerging economy like India whose population and energy consumption are poised to rise rapidly in the coming decades, renewable energy can play a vital role in decarbonizing power sector. In this context, India has targeted 33-35 percent emission intensity reduction (with respect to 2005 levels) along with large scale renewable energy targets (100GW solar, 60GW wind, and 10GW biomass energy by 2022) in INDCs submitted at Paris agreement. But large scale integration of renewable energy is a complex process which faces a number of problems like capital intensiveness, matching intermittent loads with least storage capacity and reliability. In this context, this study attempts to assess the technical feasibility of integrating renewables into Indian electricity mix by 2022 and analyze its implications on power sector operations. This study uses TIMES, a bottom up energy optimization model with unit commitment and dispatch features. We model coal and gas fired units discretely with region-wise representation of wind and solar resources. The dispatch features are used for operational analysis of power plant units under ramp rate and minimum generation constraints. The study analyzes India's electricity sector transition for the year 2022 with three scenarios. The base case scenario (no RE addition) along with INDC scenario (with 100GW solar, 60GW wind, 10GW biomass) and low RE scenario (50GW solar, 30GW wind) have been created to analyze the implications of large scale integration of variable renewable energy. The results provide us insights on trade-offs involved in achieving mitigation targets and investment decisions involved. The study also examines operational reliability and flexibility requirements of the system for integrating renewables.

Ensuring health worker job satisfaction and motivation are important if health workers are to be retained and effectively deliver health services in many developing countries, whether they work in the public or private sector. The objectives of the paper are to identify important aspects of health worker satisfaction and motivation in two Indian states working in public and private sectors. Cross-sectional surveys of 1916 public and private sector health workers in Andhra Pradesh and Uttar Pradesh, India, were conducted using a standardized instrument to identify health workers' satisfaction with key work factors related to motivation. Ratings were compared with how important health workers consider these factors. There was high variability in the ratings for areas of satisfaction and motivation across the different practice settings, but there were also commonalities. Four groups of factors were identified, with those relating to job content and work environment viewed as the most important characteristics of the ideal job, and rated higher than a good income. In both states, public sector health workers rated "good employment benefits" as significantly more important than private sector workers, as well as a "superior who recognizes work". There were large differences in whether these factors were considered present on the job, particularly between public and private sector health workers in Uttar Pradesh, where the public sector fared consistently lower (P public sector, where all 17 items had greater discordance for public sector workers than for workers in the private sector (P < 0.001). There are common areas of health worker motivation that should be considered by managers and policy makers, particularly the importance of non-financial motivators such as working environment and skill development opportunities. But managers also need to focus on the importance of locally assessing conditions and managing incentives to ensure health workers are motivated in

In September 2005, AFD's Research Department launched a Research Program on Public Private Partnerships with an approach combining economic analysis (contractual incentives, financing of investment, etc.) with a sociological and political approach to regulatory issues. Various case studies have been conducted in different sectors (water and sanitation, power, transport) and countries. This study falls within the above research framework since India - like most major developing countries - has attempted to introduce market forces in its electric power systems. At the same time, growing concern over global climate change has put the spotlight on the need for India to control its emissions of greenhouse gases (GHG). India is currently the world's sixth biggest producer of GHG emissions, but is the second biggest if one considers the rate of augmentation of its emissions. Half of India's total GHG emissions are produced by its power sector, and 70 per cent of electricity is generated by thermal power plants, mainly from coal. Climate change mitigation in the power sector is thus a strategic issue for AFD in India. This study is structured so as to examine the intersection of these two crucial challenges in India by exploring the links between private participation in the power sector in India and the reduction of GHG emissions

Full Text Available In the context of economic reforms in general and subsequent wave of M&A in particular, this paper attempts to examine the impact of M&A on the export competitiveness of firms in the Indian manufacturing sector. By using a panel dataset of 33 industries from the period of 2000-01 to 2007-08, it is found that, the wave of M&A has enhanced the export competitiveness of firms. The industries with larger number of M&A have greater penetration in the international market. The other factors that have significantly contributed to export competitiveness include the presence of MNCs and import of foreign technology. Export competiveness is higher in the industries that have larger presence of MNCs and greater foreign technology purchase intensity. On the other hand, industries with higher capital intensity or greater selling efforts by firms have limited penetration in the international market. However, this paper did not find any significant influence of market concentration, competition from imports, in-house efforts, or profitability on export competitiveness of firms. Therefore, the findings from this paper have important policy implications in relation to the regulation of M&A and entry of MNCs as well as the import of capital goods.

The author discusses the history of the Indian refining industry and ongoing developments under the headings: the present state; refinery configuration; Indian capabilities for refinery projects; and reforms in the refining industry. Tables lists India's petroleum refineries giving location and capacity; new refinery projects together with location and capacity; and expansion projects of Indian petroleum refineries. The Indian refinery industry has undergone substantial expansion as well as technological changes over the past years. There has been progressive technology upgrading, energy efficiency, better environmental control and improved capacity utilisation. Major reform processes have been set in motion by the government of India: converting the refining industry from a centrally controlled public sector dominated industry to a delicensed regime in a competitive market economy with the introduction of a liberal exploration policy; dismantling the administered price mechanism; and a 25 year hydrocarbon vision.

Full Text Available Abstract Background Ensuring health worker job satisfaction and motivation are important if health workers are to be retained and effectively deliver health services in many developing countries, whether they work in the public or private sector. The objectives of the paper are to identify important aspects of health worker satisfaction and motivation in two Indian states working in public and private sectors. Methods Cross-sectional surveys of 1916 public and private sector health workers in Andhra Pradesh and Uttar Pradesh, India, were conducted using a standardized instrument to identify health workers' satisfaction with key work factors related to motivation. Ratings were compared with how important health workers consider these factors. Results There was high variability in the ratings for areas of satisfaction and motivation across the different practice settings, but there were also commonalities. Four groups of factors were identified, with those relating to job content and work environment viewed as the most important characteristics of the ideal job, and rated higher than a good income. In both states, public sector health workers rated "good employment benefits" as significantly more important than private sector workers, as well as a "superior who recognizes work". There were large differences in whether these factors were considered present on the job, particularly between public and private sector health workers in Uttar Pradesh, where the public sector fared consistently lower (P P Conclusion There are common areas of health worker motivation that should be considered by managers and policy makers, particularly the importance of non-financial motivators such as working environment and skill development opportunities. But managers also need to focus on the importance of locally assessing conditions and managing incentives to ensure health workers are motivated in their work.

Full Text Available The purpose of this paper is to empirically test the claim made by Stern Stewart & Company that economic value added is a better metric that traditional earning based measures in explaining market value. For better exposition, a sample of 325 Indian firms has been divided into two parts- 170 firms belonging to Indian manufacturing companies and 155 companies belonging to the Indian service sector. After performing univariate and multivariate regression analyses, the results of the study reveal that the operating income has a strong linkage with market value added in both manufacturing and service sectors. For both the sectors, the economic value added shows weaker but positive relationship with the market value added.

Full Text Available In the age of relentless global competition, constantly improving technology and better information systems, managers are often compelled to devise new strategies to maintain sustained competitive advantage while adopting new business management approaches. So, in this paper, an activity based costing (ABC model is proposed for a raw material handling section of an Indian steel plant. The results obtained from ABC model application in the said department facilitates quantification of the unit cost of each process, analysis of various activities in order to identify inefficiency, setting-up of better budget allocation, initiation of cost minimization procedure and establishment of an efficient resource requirement plan. Moreover, the cost information derived from ABC model is compared with that extracted from the traditional costing system to demonstrate that ABC model can significantly minimize the product cost distortion resulting from unsystematic allocation of overhead costs. This paper also discusses the practical implication of the implemented ABC model with respect to its critical role in effective resource control, improved strategic and operational decision making, and aid in continuous improvement through internal cost minimization in the department.

Voluntary GHG reduction of industrial sectors in Taiwan.
Chen, Liang-Tung; Hu, Allen H
2012-08-01
The present paper describes the voluntary greenhouse gas (GHG) reduction agreements of six different industrial sectors in Taiwan, as well as the fluorinated gases (F-gas) reduction agreement of the semiconductor and Liquid Crystal Display (LCD) industries. The operating mechanisms, GHG reduction methods, capital investment, and investment effectiveness are also discussed. A total of 182 plants participated in the voluntary energy saving and GHG reduction in six industrial sectors (iron and steel, petrochemical, cement, paper, synthetic fiber, and textile printing and dyeing), with 5.35 Mt reduction from 2004 to 2008, or 33% higher than the target goal (4.02 Mt). The reduction accounts for 1.6% annual emission or 7.8% during the 5-yr span. The petrochemical industry accounts for 49% of the reduction, followed by the cement sector (21%) and the iron and steel industry (13%). The total investment amounted to approximately USD 716 million, in which, the majority of the investment went to the modification of the manufacturing process (89%). The benefit was valued at around USD 472 million with an average payback period of 1.5 yr. Moreover, related energy saving was achieved through different approaches, e.g., via electricity (iron and steel), steam and oil consumption (petrochemical) and coal usage (cement). The cost for unit CO(2) reduction varies per industry, with the steel and iron industrial sector having the highest cost (USD 346 t(-1) CO(2)) compared with the average cost of the six industrial sectors (USD 134 t(-1) CO(2)). For the semiconductor and Thin-Film Transistor LCD industries, F-gas emissions were reduced from approximately 4.1 to about 1.7 Mt CO(2)-eq, and from 2.2 to about 1.1 Mt CO(2)-eq, respectively. Incentive mechanisms for participation in GHG reduction are also further discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Full Text Available Carbon and carbon-relevant hydrographic and hydrochemical ancillary data from previously not publicly available cruises were retrieved and recently merged to a new data base, CARINA (CARbon IN the Atlantic. The initial North Atlantic project, an international effort for ocean carbon synthesis, was extended to include the Arctic Mediterranean Seas (Arctic Ocean and Nordic Seas and all three sectors of the Southern Ocean. Of a total of 188 cruises, 37 cruises are part of the Southern Ocean. The present work focuses on data collected in the Indian sector (20° S–70° S; 30° E–150° E. The Southern Indian Ocean dataset covers the period 1992–2004 and includes seasonal repeated observations. Parameters including salinity, dissolved inorganic carbon (TCO2, total alkalinity (TA, oxygen, nitrate, phosphate and silicate were examined for cruise-to-cruise and overall consistency. In addition, data from an existing, quality controlled data base (GLODAP were introduced in the CARINA analysis to improve data coverage in the Southern Ocean. A global inversion was performed to synthesize the information deduced from objective comparisons of deep measurements (>1500 m at nearby stations (generally <220 km. The corrections suggested by the inversion were allowed to vary within a fixed envelope, thus accounting for ocean interior variability. The adjustments applied to CARINA data and those recommended for GLODAP data, in order to obtain a consistent merged dataset, are presented and discussed. The final outcome of this effort is a new quality controlled data base for TCO2 and other properties of the carbon system that can now be used to investigate the natural variability or stability of ocean chemistry and the accumulation of anthropogenic carbon. This data product also offers an important new synthesis of seasonal to decadal observations to validate ocean biogeochemical models in a region where available historical data were very

Diarrhea remains a leading cause of death among children under five in India. Public health sector is an important source for diarrhea treatment with oral rehydration salts (ORS) and zinc. In 2010, Micronutrient Initiative started a project to improve service delivery for childhood diarrhea management through public health sector in Gujarat, Uttar Pradesh (UP) and Bihar. This paper aims to highlight feasible strategies, experiences and lessons learned from scaling-up zinc and ORS for childhood diarrhea management in the public sector in three Indian states. The project was implemented in six districts of Gujarat, 12 districts of UP and 15 districts of Bihar, which includes 10.5 million children. Program strategies included capacity building of health care providers, expanding service delivery through community health workers (CHWs), providing supportive supervision to CHWs, ensuring supplies and conducting monitoring and evaluation. The lessons described in this paper are based on program data, government documents and studies that were used to generate evidence and inform program scale-up. 140 000 health personnel, including CHWs, were trained in childhood diarrhea management. During three years, CHWs had sustained knowledge and have treated and reported more than three million children aged 2-59 months having diarrhea, of which 84% were treated with both zinc and ORS. The successful strategies were scaled-up. It is feasible and viable to introduce and scale-up zinc and ORS for childhood diarrhea treatment through public sector. Community-based service delivery, timely and adequate supplies, trained staff and pro-active engagement with government were essential for program success.

Full Text Available This study endeavours at measuring bank competition in Indian loan market using a new competitiveness index, the Augmented Relative Profit Difference (ARPD, which quantifies the impact of marginal costs on performance, measured in terms of market shares. This study yields two major insights. First, the theoretical foundation of the ARPD is very robust as compared to other conventional measures. Second, applying this unbiased competition indicator to Indian bank loan markets shows that financial reform indeed has contributed to significant improvements in competition. As regards, the competition among specific types of banks, we found public sector banks and private sector banks are comparatively more competitive than foreign banks. The empirical finding indicates that the Indian loan market is monopolistic in nature.

Until recently Oman was a country of emigration, but by 1980 an estimated 200,000 foreign workers were in the country due to the petroleum boom. Almost 1/3 of the estimated 300,000 Indian workers in the Gulf states were in Oman, a country whose colonial heritage was closely tied to that of India and many of whose inhabitants still speak Urdu. The number of work permits granted to Indians working in the private sector in Oman increased from 47,928 in 1976 to 80,787 in 1980. An estimated 110,000 Indians were working in Oman in 1982, the great majority in the construction and public works sector. A few hundred Indian women were employed by the government of Oman, as domestics, or in other capacities. No accurate data is available on the qualifications of Indian workers in Oman, but a 1979 survey suggested a relatively low illiteracy rate among them. 60-75% of Indians in Oman are from the state of Kerala, followed by workers from the Punjab and the southern states of Tamil Nadu and Andhra Pradesh and Bombay. Indian workers are recruited by specialized agencies or by friends or relatives already employed in Oman. Employers in Oman prefer to recruit through agencies because the preselection process minimizes hiring of workers unqualified for their posts. Officially, expenses of transportation, visas, and other needs are shared by the worker and the employer, but the demand for jobs is so strong that the workers are obliged to pay commissions which amount to considerable sums for stable and well paying jobs. Wages in Oman are however 2 to 5 times the level in India. Numerous abuses have been reported in recruitment practices and in failure of employers in Oman to pay the promised wages, but Indian workers have little recourse. At the same level of qualifications, Indians are paid less then non-Omani Arabs, who in turn receive less than Oman nationals. Indians who remain in Oman long enough nevertheless are able to support families at home and to accumulate considerable

The role of pre-strain on hydrogen embrittlement susceptibility of Indian Reduced Activation Ferritic Martensitic Steel was investigated using constant nominal strain-rate tension test. The samples were pre-strained to different levels of plastic strain and their mechanical behavior and mode of fracture under the influence of hydrogen was studied. The effect of plastic pre-strain in the range of 0.5–2% on the ductility of the samples was prominent. Compared to samples without any pre-straining, effect of hydrogen was more pronounced on pre-strained samples. Prior deformation reduced the material ductility under the influence of hydrogen. Up to 35% reduction in the total strain was observed under the influence of hydrogen in pre-strained samples. Hydrogen charging resulted in increased occurrence of brittle zones on the fracture surface. Hydrogen Enhanced Decohesion (HEDE) was found to be the dominant mechanism of fracture.

Full Text Available Testing the hypothesis of informational efficiency is a permanent preoccupation of researchers because the theories and the models of modern finance are based on it. This paper presents the results obtained after testing the efficiency hypothesis, in the weak form, for the European stock market of the companies that belong to the economic steel sub-sector. Following the use of both linear and non-linear tests of autocorrelation of returns we can conclude that the European stock market in the economic steel sub-sector is inefficient from an informational point of view and the investors in these stocks may obtain better results than those of the European market in general.

The term "Biodiversity" derives from a contraction of "biological diversity" and commonly refers to a measure of the variety of organisms, which are present in different ecosystems, by considering genetic variation, ecosystem variation, or species variation within an area, biome, or planet. Biodiversity is receiving an ever-increasing attention at many levels of European society as well as from many industrial sectors, and a variety of actions are being put in place in order to protect, preserve and increase it. The present paper provides examples of the capabilities and potentials of the steel sector with respect to biodiversity. In effect, steel is a valuable and fundamental structural material in order to develop measures and systems for protection of biodiversity. On the other hand, biodiversity can represent for the steel industry not only a heritage to preserve, but, through its functional traits, it can become an opportunity, offering an ecosystem's perspective to all industrial companies. In the paper, steel relevant topics and applications are analyzed leading to the conclusion that biodiversity should be exploited and can play a role with potentially relevant benefits both for the company and for local communities.

Full Text Available In the article the author analyses the role of government in developing the information technology sector in India, specifically its influence on the three factors that determine the development of the information technology sector: human resources, launch capital and infrastructure. By developing these factors, the Indian government has succeeded in prompt formation and promotion of the information technology sector. The development of human capital is mainly realized by developing public education programs. The establishment of close ties with the Indian diaspora played a crucial role. The diaspora acted as a link for transmission to India of expertise, investment and knowledge. The availability of start-up capital, especially venture capital, is another essential component for the success of the national information technology sector. The conditions created by a government for the development of the institution of venture investment in the country will be of fundamental importance. Thanks to the measures taken by the government of India, venture capital investment has become the main form of financing for start-ups in the information technology sector in India. Developed infrastructure is also an important factor in the development of the information technology sector. In India, a developing country with a vast territory, there was a problem of infrastructure development, and software technology parks became a solution to this problem for companies in the information technology sector. Over the past 20 years, software technology parks in India has evolved so that industrial parks created almost 50% of the total exports of the IT sector in India. The demonstrated state policy can be characterized as the model of state technological entrepreneurship according to which the Indian government played the roles of regulator, producer and promoter in the information technology sector and continues to do so until the present day.
Predator–prey analysis using system dynamics: An application to the steel industry
Directory of Open Access Journals (Sweden)
Douglas Crookes
2016-12-01
Full Text Available In this paper, we use a predator–prey model to simulate intersectoral dynamics, with the global steel sector as the prey that supplies inputs and the automotive sector as the predator that demands its inputs. A further prey, an additional upstream supply sector, namely the iron ore sector, is added to reflect the implications of scarcity and resource limitations for industrial development and economic prospects. We find that capacity constraints in the steel industry could limit the future supply of vehicles, a result exacerbated by the unsustainable use of iron ore reserves. The solution is not for marginal steel industries to close, but for steelmakers to adapt and move to less resource-demanding secondary steelmaking technology rather than focusing on primary steelmaking. The forecasting capabilities of the model are compared with the outputs from a neural-network model. Although the results are comparable over the short term (±10 years, over the long term, results diverge, showing that forecasting steel-industry dynamics is complex and that further work is required to disentangle the drivers of supply and demand. This study indicates the potential advantages of using predator–prey models in modelling the supply chain in economics.

Measurements of partial pressure of carbon dioxide (pCO 2 ), total dissolved inorganic carbon (TCO 2 ), total alkalinity (TA) and chlorophyll a (Chl a) have been made in surface water in the southwestern Indian sector of the Southern Ocean (20-85 degE) in the austral summer (INDIVAT V cruise, January-February 1987). Between Antarctica and Africa, pCO 2 distribution was linked to the oceanic frontal zones and Chl a variations. The pCO 2 spatial structure was very close to that explored in summer 1967 in the same region but the pCO 2 differences between the ocean and the atmosphere were smaller in 1987 than 20 years ago. At all latitudes strongly contrasting surface pCO 2 characteristics were found between eastern (around 80 degE) and western (around 25 degE) regions; CO 2 sources were mainly in the west and CO 2 sinks in the east. South of 60 degS, the contrast could be due to biological activity. Between 60 degS and the Antarctic Polar Front, intensification of upwelling might be responsible for the higher pC) 2 values in the west.37 refs.; 4 figs

Full Text Available The metallurgy of Indian swords shows many differences from that of European swords. The distinction between "Damascus Steel" (or wootz and crucible steel is explained. Ten broken blades from the Armoury of the Nizams of Hyderabad were made available for microscopic examination. Six of these seem to been made from crucible steels, and are of notably high quality. By contrast, a group of six randomly collected from Private Collections in England were also examined. Only one of these was made of crucible steel, and three of the others were of very mediocre quality. This perhaps represents the quality of blades available to the average Indian soldier.
La metalurgia de las espadas indias presenta notables diferencias en comparación con la de las europeas. Se explica la distinción entre el ‘acero de Damasco’ (o wootz y el acero de crisol. Se ha realizado un análisis microscópico de un conjunto de diez hojas rotas de espada depositadas en la Armería de los Nizams de Hyderabad. Seis de ellas parecen haber sido realizadas a partir de acero de crisol, y son de elevada calidad. En contraste, se examinó también un grupo de seis espadas de colecciones privadas en Inglaterra. Sólo una de ellas estaba fabricada con acero de crisol, y tres de las otras eran de calidad muy mediocre. Esto representa quizá la calidad de las hojas de espada al alcance del soldado medio indio.

Kalyani Carpenter Special Steels Ltd is an alloy steel plant, where a variety of alloy steel grades are produced for automotive, defence, nuclear and aerospace applications. The plant has developed expertise in processing of several alloy steel grades of superior quality that meets stringent specifications. Primary steel is processed through a combination of electric arc furnace, ladle furnace and vacuum degassing where stringent control over dephosphorisation, desulphurization, deoxidation is effected to get a refined high quality steel. The molten steel is cast through continuous casting of slabs or ingot casting. In grades specific to nuclear application, the primary cast products are further subjected to electroslag remelting to achieve further freedom from inclusions and to achieve a favourable solidification grain structure, which ultimately improve the hot workability of the alloy steel. Appropriate choice of slag and operating parameters are needed for realising the required ingot quality. The present study would examine the processing and quality aspects of some important grades of steels used in nuclear industry namely ferritic 9Cr-1Mo steel, martensitic stainless steels 403, 410, precipitation hardenable 17-4 PH stainless steel and austenitic 321, 316LN stainless steel, which were made and supplied for applications to Indian nuclear industry. The expertise developed in processing the steels in terms of melting, heat treatment and their relationship to structural features and mechanical properties would be highlighted. (author)

Full Text Available The study attempts to capture conditional variance of Indian banking sector’s stock market returns across the years 2005 to 2015 by employing different GARCH based symmetric and asymmetric models. The results report existence of persistency as well as leverage effects in the banking sector return volatility. On an expected note, the global financial crisis increased conditional volatility in the Indian banking sector during the years 2007 to 2009; further evidenced from Markov regime switches. The exponential GARCH (EGARCH model is found to be the best fit model capturing time-varying variance in the banking sector. The results support strong implications for the market participants at the time of devising portfolio management strategies.

Full Text Available Environmentally conscious manufacturing has become a global attention for the iron and steel manufacturers to prevent global warming and climate change while making money. Iron and steel sector is considered as one of the most polluting sectors in the world. It is also one of the most energy intensive industries. During pig iron manufacturing, there is a number of steps that affect the environment emitting different pollutants. While some step(s may be considered critical to damage the environment among all the steps, some pollutant(s may be considered critical to affect the environment among all the pollutants. This paper proposes environmental bottleneck to consider critical step and critical pollutant simultaneously. Unless environmental bottleneck is improved, environmental performance of the entire manufacturing process may not improve significantly even if other processes (i.e. other than environmental bottleneck are taken care of. Thus, environmental bottleneck must be taken care of properly by the manufacturing organization to enable environmentally conscious manufacturing. Hence, a method should be developed to identify environmental bottleneck. Current research work uses Bayesian Networks (BN to identify environmental bottleneck. The contribution of the paper is to identify the environmental bottleneck for an Indian pig iron manufacturing organization. Results suggest that carbon monoxide (CO emission from the blast furnace is the environmental bottleneck for the current pig iron manufacturing organization. Hence, proper precautions should be considered to control the CO emission from the blast furnace.

Full Text Available In recent time, Indian manufacturing has seen technologically intensive and resource optimization based initiatives to satisfy competitive urge and to build or sustain market position. This they do by developing products either strategically or innovatively, but that is hardly distinguished or seen as a separate approach to product development. Strategically, product development is resource optimization based while innovatively, it is product differentiation focused. This paper outlines the strategic and innovative approach to product development and analyzes sector specific role of each in product development. The study is undertaken with nine product development team-leaders and resource-heads, three of each from automobile, steel and textile. It is concluded that textile is strategically skewed toward product development whereas automobile is inclined towards innovative orientation. The biggest limitation of this study is smaller sample-size because respondents are reluctant to disclose new technical initiatives and composition of product development.

The car industry is facing pressure because of the growing demand for more fuel-efficient passenger cars. In order to limit energy consumption and air pollution the weight of the car body has to be reduced. At the same time, high levels of safety have to be guaranteed. In this situation, the choice of material becomes a key decision in car design. As a response to the requirements of the automotive sector, high strength steels and advanced high strength steels have been developed by the steel industry. These modern steel grades offer an excellent balance of low cost, light weight and mechanical properties. (Author) 48 refs.
Energy use and carbon dioxide emissions in the steel sector in key developing countries

Iron and steel production consumes enormous quantities of energy, especially in developing countries where outdated, inefficient technologies are still used to produce iron and steel. Carbon dioxide emissions from steel production, which range between 5 and 15% of total country emissions in key developing countries (Brazil, China, India, Mexico, and South Africa), will continue to grow as these countries develop and as demand for steel products such as materials, automobiles, and appliances increases. In this report, we describe the key steel processes, discuss typical energy-intensity values for these processes, review historical trends in iron and steel production by process in five key developing countries, describe the steel industry in each of the five key developing countries, present international comparisons of energy use and carbon dioxide emissions among these countries, and provide our assessment of the technical potential to reduce these emissions based on best-practice benchmarking. Using a best practice benchmark, we find that significant savings, in the range of 33% to 49% of total primary energy used to produce steel, are technically possible in these countries. Similarly, we find that the technical potential for reducing intensities of carbon dioxide emissions ranges between 26% and 49% of total carbon dioxide emissions from steel production in these countries.

The roles of energy and material efficiency in meeting steel industry CO2 targets.
Milford, Rachel L; Pauliuk, Stefan; Allwood, Julian M; Müller, Daniel B
2013-04-02
Identifying strategies for reducing greenhouse gas emissions from steel production requires a comprehensive model of the sector but previous work has either failed to consider the whole supply chain or considered only a subset of possible abatement options. In this work, a global mass flow analysis is combined with process emissions intensities to allow forecasts of future steel sector emissions under all abatement options. Scenario analysis shows that global capacity for primary steel production is already near to a peak and that if sectoral emissions are to be reduced by 50% by 2050, the last required blast furnace will be built by 2020. Emissions reduction targets cannot be met by energy and emissions efficiency alone, but deploying material efficiency provides sufficient extra abatement potential.

2011-04-01
Full Text Available Enterprise Resource Planning (ERP is essentially a commercial software package that enables the integration of transaction - oriented data and business processes throughout an organization. In order to remain competitive in this global business scenario, the small and medium scale enterprises (SMEs are opting for ERP implementation. In Indian SME sector, the adoption of ERP is rapidly increasing. Literature shows many instances where organizations, even after implementing such novel information systems like ERP, are unable to derive the benefits of integration. It is, therefore, not surprising that implementation of enterprise information systems in general is quite difficult due to their size, scope and complexity. Therefore, there is a need to identify some issues that would lead to positive outcome for the implementation of ERP systems in the context of Indian SME sector. This paper thus attempts to identify and to prioritize the factors influencing proper implementation of ERP systems in a business organization particularly for Indian small and medium businesses (SMBs. The research presented here is specifically targeted the Indian SMEs, which have already completed the process of implementing ERP system.
Micro-Abrasion Wear Resistance of Borided 316L Stainless Steel and AISI 1018 Steel
Reséndiz-Calderon, C. D.; Rodríguez-Castro, G. A.; Meneses-Amador, A.; Campos-Silva, I. E.; Andraca-Adame, J.; Palomar-Pardavé, M. E.; Gallardo-Hernández, E. A.

The 316L stainless steel has high corrosion resistance but low tribological performance. In different industrial sectors (biomedical, chemical, petrochemical, and nuclear engineering), improvement upon wear resistance of 316L stainless steel components using accessible and inexpensive methods is critical. The AISI 1018 steel is widely used in industry, but its tribological performance is not the best among steels. Therefore, in this study the behavior of the borided 316L stainless steel and 1018 steel is evaluated under micro-abrasion wear. The boriding was carried out at 1223 K over 6 h of exposure time, resulting in a biphase layer composed of FeB/Fe2B phases. In order to evaluate Fe2B phase with no influence from FeB phase, AISI 1018 steel samples were borided at 1273 K for over 20 min and then diffusion annealed at 1273 K over 2 h to obtain a Fe2B mono-phase layer. Micro-abrasion wear resistance was evaluated by a commercial micro-abrasion testing rig using a mix of F-1200 SiC particles with deionized water as abrasive slurry. The obtained wear rates for FeB and Fe2B phases and for the 316L stainless steel were compared. Wear resistance of 316L stainless steel increases after boriding. The wear mechanisms for both phases and for the stainless steel were identified. Also, transient conditions for rolling and grooving abrasion were determined for the FeB and Fe2B phases.

Full Text Available This research paper attempts to collate literature from various sources, in an attempt to answer three pertinent questions related to healthcare in India. Firstly, what is it meant by ‘private sector’ in healthcare delivery system of India, secondly how has the private sector evolved over the decades and what has been the role of the government in propelling the growth. Finally, the paper tries to highlight some of the factors that have promoted the growth of private sector in India with specific reference to quality of medical care. The paper explicitly indicates that the deficiencies in the public health delivery system of India, was the key to growth of private infrastructure in healthcare.The shift of hospital industry for ‘welfare orientation’ to ‘business orientation’ was marked by the advent of corporate hospitals, supported by various policy level initiatives made by the government. Today, there are over 20 international healthcare brands in India with several corporate hospitals.However, a large section of the ‘private healthcare delivery segment’ is scattered and quality of medical care continues to remain a matter of concern. This paper tracks the various government initiatives to promote private investment in healthcare and attempts to explore the reasons for preference of the private sector. Surprisingly, in contrast to contemporary belief, quality of medical care doesn’t seem to be the leading cause for preference of the private sector. Except for a few select corporate and trust hospitals, quality of medical care in private sector seems to be poor and at times compromised.

A new paradigm for the Indian power sector: going beyond the 'Silver Bullet' privatisation
Energy Technology Data Exchange (ETDEWEB)
Ruet, J.
2001-07-01
This paper focuses on the Indian power sector. However, the situation in France will be briefly recalled, for the rationales of privatisation, levels of analysis and issues to be solved are not at all the same, and for a part of the solution could be drawn from the French public experience. Section one deals with the rationale for privatisation in India, as assessed by its supporters. In practice, this policy has not reached its declared targets in India (absence of commitment, delayed projects, assets 'sold for a song'). This allows space for questioning the implicit or explicit assumptions in present reforms. For privatisation is being supported due to so called 'political interference', and 'lack of money', these issues will be put in perspective with some more structural roots in inefficiency of the Indian power sector. Indeed, these two explanations are meaningless in telling why inefficient decisions are selected preferably to efficient ones. Namely, the internal organisation itself of power utilities has to be questioned. Section two focuses on the decision-making in State Electricity Boards, especially on the absence of proper tools for delegation of power (a proper budget allocation, a proper delegation of managerial power, a reporting system which makes people accountable for decisions). It shows how this leads to a decision-making system being more dependent on administrative procedures than dedicated to solve actual issues. This analysis as well explains how the inability to have assumptions strong enough to carry out 'costs vs. benefits' analysis leads to inefficiencies. This ultimately explains the disinterest of private investors or the high premiums they take. Section three calls for an inflexion to the current reforms, which do not take into account these characteristics of public utilities. Further to the experience of reform in Russia, Eastern Europe and China, this section calls for a very &apos
Financial structure in the Indian power sector
International Nuclear Information System (INIS)
Carstairs, Jamie; Ehrhardt, David
1995-01-01
In India, the private power initiative of 1991 has offered on solution to the financing problem - the private financing of generation against long-term power purchase agreements. However, this approach encounters a major problem, the financial weakness of the purchasing agents, the state electricity boards, that play a dominant role in most state's power sectors. At present the SEBs are mostly loss making; even the best performers realize returns on assets well below the cost of capital that they now face. The situation is likely to become worse as costs rise, further weakening the ability of the SEBs to sign credible long-term purchase contracts. The private sector has responded by trying to reduce its exposure to SEBs through obtaining guarantees from state and central governments. There are a number of responses to this problem. The SEBs could try to become financially stronger through both cost reduction and increased revenues from higher tariffs and better collection. However, to make the SEBs and EDs into credible long-term power purchasers, power sector reform and regulation is needed. As these actions will take time, other responses could be investigated such as reducing the role of state power utilities by, for example, giving private generators direct access to industrial consumers. The long-term solution requires more profitable SEBs, if these bodies are to continue to play a dominant role in state-level electricity provision. Profitable SEBs will have access to finance from a range of domestic and international sources. The article finishes with consideration of the factors that will affect the optimal capital structure for SEBs. (author)

Due to the growing energy needs along with increasing concerns towards control of greenhouse gas emissions, most developing countries are under pressure to find alternative methods for energy conversion and policies to make these technologies economically viable. One of the instruments that have been adopted by many industrial countries is that of the carbon tax. The rate of introducing carbon taxes however, depends upon the local economic conditions and market forces. The case of Indian power sector has been examined by using MARKAL model for introduction of carbon taxes at four different trajectories. Their implications on the power generation choices have been investigated for a time span of 25 years from the year 2000. In general large hydropower plants have emerged as the first choice followed by wind energy systems. However, cheaper availability of coal in India keeps scope of use of coal based technologies for which pressurised fluidised bed combustion technology has been found to be the balanced choice among fossil technologies. There exists a potential of reduction of greenhouse gas emissions by about 25% as compared to the 'business-as-usual' case in presence of high carbon tax rates

Production of Green Steel from Red Mud: A Novel Concept
Bhoi, Bhagyadhar; Behera, Pravas Ranjan; Mishra, Chitta Ranjan
Red mud of Indian origin contains around 55% plus of Fe2O3 and is considered as a hazardous waste for the alumina industry. For production of one tone of alumina employing the Bayer's Process, around two tones of red mud is generated from three tones of Bauxite. Conventional process of steel making is not devoid of environmental pollution. In the present investigation, efforts have been made to produce steel from red mud by adopting reduction roasting, magnetic separation and hydrogen plasma smelting route. Magnetic fraction, containing enriched iron oxide and minimal content of alumina, is produced following the first two stages which is then subjected to hydrogen plasma smelting process for production of steel. This novel concept follows a green path way for production of steel free from pollution and is termed as green steel. Further, the only by-product that is produced in the process, is water, which is eco-friendly and recyclable.

The change of CO2 emission on manufacturing sectors in Indonesia: An input-output analysis
Putranti, Titi Muswati; Imansyah, Muhammad Handry
2017-12-01
The objective of this paper is to evaluate the change of CO2 emission on manufacturing sectors in Indonesia using input-output analysis. The method used supply perspective can measure the impact of an increase in the value added of different productive on manufacturing sectors on total CO2 emission and can identify the productive sectors responsible for the increase in CO2 emission when there is an increase in the value added of the economy. The data used are based on Input-Output Energy Table 1990, 1995 and 2010. The method applied the elasticity of CO2 emission to value added. Using the elasticity approach, one can identify the highest elasticity on manufacturing sector as the change of value added provides high response to CO2 emission. Therefore, policy maker can concentrate on manufacturing sectors with the high response of CO2 emission due to the increase of value added. The approach shows the contribution of the various sectors that deserve more consideration for mitigation policy. Five of highest elasticity of manufacturing sectors of CO2 emission are Spinning & Weaving, Other foods, Tobacco, Wearing apparel, and other fabricated textiles products in 1990. Meanwhile, the most sensitive sectors Petroleum refinery products, Other chemical products, Timber & Wooden Products, Iron & Steel Products and Other non-metallic mineral products in 1995. Two sectors of the 1990 were still in the big ten, i.e. Spinning & weaving and Other foods in 1995 for the most sensitive sectors. The six sectors of 1995 in the ten highest elasticity of CO2 emission on manufacturing which were Plastic products, Other chemical products,Other fabricated metal products, Cement, Iron & steel products, Iron & steel, still existed in 2010 condition. The result of this research shows that there is a change in the most elastic CO2 emission of manufacturing sectors which tends from simple and light manufacturing to be a more complex and heavier manufacturing. Consequently, CO2 emission jumped

Sequential fatigue-creep tests were conducted on Indian reduced activation ferritic–martensitic steel at 823 K leading to sharp decrease in residual creep life with increase in prior fatigue exposures. Extensive recovery of martensitic-lath structure taking place during fatigue deformation, manifested as cyclic softening in the cyclic stress response, shortens the residual creep life. Based on the experimental results, cyclic softening occurring during fatigue stage can be correlated with residual creep life, evolving in an empirical model which predicts residual creep life as a function of cyclic softening. Predicted creep lives for specimens pre-cycled at various strain amplitudes are explained on the basis of mechanism of cyclic softening.

Full Text Available The goal of this paper is to investigate the evolution of the leading Indian business-groups under the conditions of economical liberalization. It is shown that the role of modern business-groups in the Indian economy is determined by their high rate in the gross domestic product (GDP, huge overall actives, substantial pert in the e[port of goods and services, as well as by their activities in modern branch structure formatting, and developing labor-intensive and high-tech branches. They strongly influence upon economical national strategies, they became a locomotive of internationalization and of transnationalization of India, the basis of the external economy factor system, the promoters of Indian "economical miracle" on the world scene, and the dynamical segment of economical and social development of modern India. The tendencies of the development of the leading Indian business groups are: gradual concentration of production in few clue sectors, "horizontal" structure, incorporation of the enterprises into joint-stock structure, attraction of hired top-managers and transnationaliziation. But against this background the leading Indian business-groups keep main traditional peculiarities: they mostly still belong to the families of their founders, even today they observe caste or communal relations which are the basis of their non-formal backbone tides, they still remain highly diversificated structures with weak interrelations. Specific national ambivalence and combination of traditions and innovations of the leading Indian business-groups provide their high vitality and stability in the controversial, multiform, overloaded with caste and confessional remains Indian reality. We conclude that in contrast to the dominant opinion transformation of these groups into multisectoral corporations of the western type is far from completion, and in the nearest perspective they will still possess all their peculiarities and incident social and economical

Full Text Available A large component of the Indian economy is still in the unorganised (or informal sector. The emergence of new intermediaries leveraging the Internet has contributed significantly to organising the hitherto unorganised sector. We discuss the case of the Indian real estate industry and elucidate how Internet-based intermediaries have mitigated the problems associated with the unorganised nature of the industry. The three primary problems associated with the unorganised nature of the industry are adverse selection, moral hazard, and weak contract enforcement. Leaders representing four leading real estate platforms discuss how organising the real estate business as a platform business model helps mitigate these risks.

The Indian Ocean formed as a result of the fragmentation and dispersal of East Gondwanaland since the Jurassic. The deep ocean basins in the Indian Ocean contain the imprints of this plate tectonic history, which is related with several major events such as the Kerguelen, Marion and Reunion hotspot inception and the Indo-Eurasian collision. A broad model for evolution of the Indian Ocean was proposed in the early 1980s. Subsequently, French scientists collected a large amount of magnetic data from the western and southern parts of the Indian Ocean while Indian and Australian scientists collected considerable volumes of magnetic data from the regions of Indian Ocean around their mainlands. Using these data, the Indian, French and Australian researchers independently carried out investigations over different parts of the Indian Ocean and provided improved models of plate kinematics at different sectoral plate boundaries. Under two Indo-French collaborative projects, detailed magnetic investigations were carried out in the Northwestern and Central Indian Ocean by combining the available magnetic data from conjugate regions. Those projects were complemented by additional area-specific studies in the Mascarene, Wharton, Laxmi and Gop basins, which are characterized by extinct spreading regimes. These Indo-French projects provided high resolution and improved plate tectonic models for the evolution of the conjugate Arabian and Eastern Somali basins that constrain the relative motion between the Indian-African (now Indian-Somalian) plate boundaries, and the conjugate Central Indian, Crozet and Madagascar basins that mainly constrain the relative motions of Indian-African (now Capricorn-Somalian) and Indian-Antarctic (now Capricorn-Antarctic) plate boundaries. During the same period, Australian scientists carried out investigations in the southeastern part of the Indian Ocean and provided an improved understanding of the plate tectonic evolution of the Indian

In recognition of their competitive vulnerability, a set of special rules have been devised for managing sectors such as iron and steel within the EU ETS. Under these rules, the EU steel sector has received free allocations in excess of their compliance needs to now, and will continue to receive some free allowances up to 2020. However, perceptions of the sector's competitive vulnerability have been largely based on inherently hypothetical analyses which rely heavily on counterfactual scenarios and abatement cost estimates often provided by firms themselves. This paper explores how the three largest steel firms in the EU (AcerlorMittal, Corus, and ThyssenKrupp) have sought to strategically exaggerate their vulnerability to carbon pricing to the effect of an inefficient policy outcome. We conduct a qualitative assessment of two of the key narratives underpinning the competitive vulnerability argument of EU steel companies – lack of abatement opportunities and inability to pass through cost increases – based on interviews, case studies, and publicly available data. We find that these arguments provide only partial and weak justifications for competitive loss and preferential treatment under the EU ETS. The strategy however remains successful due to information asymmetry and the peculiar political economy of EU climate regulation. - Highlights: ► We evaluate carbon leakage and vulnerability claims to climate policy by EU Steel companies. ► We find these claims are exaggerated and form key part of companies' climate political strategy. ► The success of this strategy implicates information asymmetry and the broader political economy of regulation within the EU. ► It has proved successful in helping the sector achieve free emission allocations in the EUETS.

The steel industry maintains its important position in the context of the Italian production involving thousands of workers. The iron and steel processes are divided into primary steel industry, production of intermediate minerals, and secondary steel, scrap from the production of semi-finished industrial and consumer sector (metal inserted into components and metal used for dissipative uses, primarily coatings) and industrial waste. The paper presents the results of environmental monitoring carried out in some electric steel plant for the measurement of airborne chemicals that characterize the occupational exposure of workers employed in particular area like electric oven, to treatment outside the furnace, continuous casting area. For the sampling of the pollutants were used both personal and in fixed positions samplers. The pollutants measured are those typical of steel processes inhalable dust, metals, respirable dust, crystalline silica, but also Polycyclic Aromatic Hydrocarbons (PAH), polychlorinated dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs).

A LCA feasibility study was undertaken to determine the environmental impact of an Eco-magnesium process route by recycled chips to manufacture panel for the automotive sector to be compared with comparative scenarios, a non-recycled carbon fiber reinforced polymer (CFRP) and a baseline steel-made component scenario. The objective of this LCA study was to assess the actual benefits of a lightweight solution considering the whole life cycle, including the dirty-phase (i.e. the "cradle-to-exit gate" stage) that impacts differently for the different materials. For this reason the analysis has regarded the net "cradle-to-grave" scenario. Different automotive floor pans were then compared considering the rate of fuel consumption during vehicle operation — i.e. the fuel-mass correlation factor — and the different material substitution factors allowed by the different materials selected.
Efficient Project Delivery Using Lean Principles - An Indian Case Study
Kovvuri, P. Ramachandra Reddy; Sawhney, Anil; Ahuja, Ritu; Sreekumar, Aiswarya
2016-03-01
Construction industry in India is growing at a rapid pace. Along with this growth, the industry is facing numerous challenges that are making delivery of projects inefficient. Experts believe that capacity constraints in the industry need to be addressed immediately. Government has recommended `introduction of efficient technologies and modern management techniques' to increase the productivity of the industry. In this context, lean principles can act as a lever to make project delivery more efficient and provide the much needed impetus to the Indian construction sector. Around the globe lean principles are showing positive results on the projects. Project teams are reporting improvements in construction time, cost and quality along with softer benefits of enhanced collaboration, coordination and trust in project teams. Can adoption of lean principles provide similar benefits in the Indian construction sector? This research was conducted to answer this question. Using an action research approach a key lean construction tool called Last Planner System (LPS) was tested on a large Indian construction project. The work described in this work investigates the improvements achieved in project delivery by adopting LPS in Indian construction sector. Comparison in pre- and post-implementation data demonstrates increase in the certainty of work-flow and improves schedule compliance. This is measured through a simple LPS metric called percent plan complete. Explicit improvements in schedule performance are seen during 8 week LPS implementation along with implicit improvements in coordination, collaboration and trust in the project team. This work reports the findings of LPS implementation on the case study project outlining the barriers and drivers to adoption, strategies needed to ensure successful implementation and roadmap for implementation. Based on the findings the authors envision that lean construction can make project delivery more efficient in India.

Full Text Available Economic think tanks predict India to be the world’s largest economy by 2050. This would require India to accelerate its industrial and infrastructure development. Industrialization based economic development will have a negative impact on the environment and hence sustainable development. Such steps could affect the social and environmental bottom line of the national economy. In recent years, a number of regulatory measures have been proposed by the Indian government to ensure corporate support to the goals of sustainable and inclusive development. The objective of these regulations is to achieve triple bottom line based growth. Notable among them is the mandatory Corporate Social Responsibility (CSR guidelines for public sector undertakings, first issued in April, 2010. I study the possibility and problems created by this effort by analyzing the policy documents and interviewing managers responsible for implementing CSR programmers in Indian public sector. Managers interviewed came from hydropower, coal, power distribution and shipping industries. Based on the study, four areas are identified that requires attention for effective linking between sustainable development and CSR; stakeholder engagement, institutional mechanisms, capacity building and knowledge management. Both government-public sector and public sector-community engagements have to be more streamlined. Institutional mechanisms have to be developed to see that CSR projects are effective and delivering. Importantly, managers at all levels need a better understanding of CSR and sustainable development. Since most projects are in rural areas, understanding of rural issues and sustainability is very important. Finally, such a large scale exercise in CSR should have a knowledge management mechanism to learn from the achievements and mistakes of the early years. I discuss the implication of the findings on India and other emerging economies many of which are struggling to balance

AISI 304 and 316 austenitic stainless steels were invented in the early 1900s and are still trusted by materials and mechanical engineers in numerous sectors because of their good combination of strength, ductility, and corrosion resistance, and thanks to decades of experience and data. This article is part of an effort focusing on tailoring the plasticity of both types of steels to nuclear applications. It provides a synthetic and comprehensive review of the plasticity mechanisms in austenitic steels during tensile tests below 400 °C. In particular, formation of twins, extended stacking faults, and martensite, as well as irradiation effects and grain rotation are discussed in details. - Highlights: • This article is part of an effort to tailor the plasticity of 304L and 316L steels for nuclear applications. • It reviews mechanisms controlling plasticity of austenitic steels during tensile tests. • Formation of twins, extended stacking faults, and martensite, grain rotation, and irradiation effects are discussed.

China faces a significant challenge in the years ahead to continue to provide essential materials and products for a rapidly-growing economy while addressing pressing environmental concerns. China's industrial sector is heavily dependent on the country's abundant, yet polluting, coal resources. While tremendous energy conservation and environmental protection achievements were realized in the industrial sector in the past, there remains a great gulf between the China's level of energy efficiency and that of the advanced countries of the world. Internationally, significant energy efficiency improvement in the industrial sector has been realized in a number of countries using an innovative policy mechanism called Voluntary Agreements. This paper describes international experience with Voluntary Agreements in the industrial sector as well as the development of a pilot program to test the use of such agreements with two steel mills in Shandong Province, China.
How Will Copper Contamination Constrain Future Global Steel Recycling?
Daehn, Katrin E; Cabrera Serrenho, André; Allwood, Julian M
2017-06-06
Copper in steel causes metallurgical problems, but is pervasive in end-of-life scrap and cannot currently be removed commercially once in the melt. Contamination can be managed to an extent by globally trading scrap for use in tolerant applications and dilution with primary iron sources. However, the viability of long-term strategies can only be evaluated with a complete characterization of copper in the global steel system and this is presented in this paper. The copper concentration of flows along the 2008 steel supply chain is estimated from a survey of literature data and compared with estimates of the maximum concentration that can be tolerated in steel products. Estimates of final steel demand and scrap supply by sector are taken from a global stock-saturation model to determine when the amount of copper in the steel cycle will exceed that which can be tolerated. Best estimates show that quantities of copper arising from conventional scrap preparation can be managed in the global steel system until 2050 assuming perfectly coordinated trade and extensive dilution, but this strategy will become increasingly impractical. Technical and policy interventions along the supply chain are presented to close product loops before this global constraint.

The complexities of the manufacturing sector unquestionably make energy-use analysis more difficult here than in other energy-using sectors. Therefore, this paper examines only one energy-intensive industry within the manufacturing sector--blast furnaces and steel mills (SIC 3312). SIC 3312, referred to as the iron and steel industry in this paper, is profiled with an examination of the products produced, how they are produced, and energy used. Energy trends from 1985 to 1994 are presented for three major areas of analysis. The first major area includes trends in energy consumption and expenditures. The next major area includes a discussion of energy intensity--first as to its definition, and then its measurement. Energy intensities presented include the use of different (1) measures of total energy, (2) energy sources, (3) end-use energy measures, (4) energy expenditures, and (5) demand indicators-economic and physical values are used. The final area of discussion is carbon emissions. Carbon emissions arise both from energy use and from certain industrial processes involved in the making of iron and steel. This paper focuses on energy use, which is the more important of the two. Trends are examined over time

Full Text Available The subantarctic frontal zone surveyed during the April-May 1991 SUZIL cruise in the Crozet-Kerguelen-Amsterdam area shows a strong horizontal (north to south gradient of dissolved silicate, increasing with depth, from 5 to 10 µmolSi kg-1 at 100 m, and 10 to 70 µmolSi kg-1 at 600 m. The northern limit of this frontal zone, which is formed by the confluence of the Subtropical and Subantarctic Fronts, is delimited at the surface by the 2 µmolSi kg-1 silicate isoline. Silicate-salinity diagrams also allow different water regimes to be positioned relative to the frontal zone. This sloping interface is between two water bodies, one to the north with more saline subtropical waters of less concentrated silicate than the southern one, corresponding to subantarctic waters which are less saline and richer in silicate. It is concluded that dissolved silicate can be used as a useful tracer of frontal zone water masses in the Indian sector of the Southern Ocean, providing a sound complement to other hydrographic data.
Power sector reform in India: current issues and prospects

Singh, Anoop
2006-01-01
Power sector reforms in India were initiated at a juncture when the sector was plagued with commercial losses and burgeoning subsidy burden. Investment in the sector was not able to keep pace with growing demand for electricity. This paper takes stock of pre-reform situation in Indian power sector and identifies key concerns that led to initiation of the process of reform. The paper discusses major policy and regulatory changes undertaken since the early 1990s. The paper also illustrates changes in the market structure as we move along the reform process. We also discuss some of the major provisions of the recently enacted Electricity Act 2003 that aims to replace the prevailing acts which govern the functioning of the power sector in the country. In this context, we discuss two issues arising out of it, namely open access and multi-year tariff that we think would have a significant bearing on the performance of the sector in the near future. The paper also evaluates the reform process in the light of some of the regulatory changes undertaken. Finally, the paper briefly discusses the issues involved in introduction of competition in the power sector primarily through development of a market for bulk power

Energy efficiency indicators used for evaluating industrial activities at the national level are often based on statistics reported in international databases. In the case of the Swedish iron and steel sector, energy consumption statistics published by Odyssee, Eurostat, the IEA (International Energy Agency), and the United Nations differ, resulting in diverging energy efficiency indicators. For certain years, the specific energy consumption for steel is twice as high if based on Odyssee statistics instead of statistics from the IEA. The analysis revealed that the assumptions behind the allocation of coal and coke used in blast furnaces as energy consumption or energy transformation are the major cause for these differences. Furthermore, the differences are also related to errors in the statistical data resulting from two different surveys that support the data. The allocation of coal and coke has implications when promoting resource as well as energy efficiency at the systems level. Eurostat's definition of energy consumption is more robust compared to the definitions proposed by other organisations. Nevertheless, additional data and improved energy efficiency indicators are needed to fully monitor the iron and steel sector's energy system and promote improvements towards a greener economy at large. - Highlights: • Energy statistics for the iron and steel sector diverge in international databases. • Varying methods have implications when monitoring energy and resource efficiency. • Allocation of blast furnaces as transformation activities is behind the differences. • Different statistical surveys and human error also contribute to diverging results

Full Text Available This paper examines the higher education system in India together with its status regarding internationalisation, and presents the case for the higher education sector in India to embrace internationalisation. Starting with an overview of the academic literature around the concepts of globalisation and internationalisation, and their interrelationship particularly in the context of higher education, the paper focuses on the specific issues of Indian higher education especially within the context of internationalisation. Reviewing the current landscape of the Indian higher education sector, the paper concludes that, in the context of a globally connected world, higher education in India is characterised by asymmetry in flows and unclear policies. Recommending that the internationalisation strategy focuses on the four strands of student and programme mobility; infrastructure and policy support; development of research capability; and the employment of technology as an enabler, the paper concludes that a clear approach to internationalisation would offer the potential to secure India a formidable global standing in higher education.
Morphology of equatorial plasma bubbles during low and high solar activity years over Indian sector

In the present study, slant total electron content (STEC) data computed from ground based GPS measurements over Hyderabad (Geog. Lat. 17.41° N, geog. long. 78.55° E, mag. lat. 08.81° N) and two close stations at Bangalore (Geog. Lat. 13.02°/13.03° N, geog. long. 77.57°/77.51° E, mag. lat. 04.53°/04.55° N) in Indian region during 2007-2012, have been used to study the occurrences and characteristics of equatorial plasma bubbles (EPBs). The analysis found maximum EPB occurrences during the equinoctial months and minimum during the December solstice throughout 2007-2012 except during the solar minimum years in 2007-2009. During 2007-2009, the maximum EPB occurrences were observed in June solstice which could not be predicted by the model proposed by Tsunoda (J. Geophys. Res., 90:447-456, 1985). The equinox maximum in EPB occurrences for high solar activity years could be caused by the vertical F-layer drift due to pre-reversal electric field (PRE), and expected to be maximum when day-night terminator aligns with the magnetic meridian i.e. during the equinox months whereas maximum occurrences during the solstice months of solar minimum could be caused by the seed perturbation in plasma density induced by gravity waves from tropospheric origins. Generally EPB occurrences are found to be more prominent during nighttime hours (2000-2400 hours) than the daytime hours. Peak in EPB occurrences is in early night for high solar activity years whereas same is late night for low solar activity. The day and nighttime EPB occurrences have been analyzed and found to vary in accordance with solar activity with an annual correlation coefficient (R) of ˜0.99 with F_{10.7} cm solar Flux. Additionally, solar activity influence on EPB occurrences is seasonal dependent with a maximum influence during the equinox season (R=0.88) and a minimum during winter season (R =0.73). The solar activity influences on EPB occurrences are found in agreement with the previous works reported in

In India population and economic growth is expected to create serious power shortages triggering the need for new power generation capacity. The situation is worsened on account of stagnant conditions prevailing in the country during the past few years. The opening of economy to the global market is expected to usher in an increased economic growth bringing in its wake greater demand for power. It will, thus, be seen that to cater these requirements the power sector industry in the country will have to grow at a much faster rate in the near future. However, to have a correct perspective of the emerging scenario, it might be worthwhile to have a look at the past patterns of development. (author). 9 refs., 5 tabs

Stainless steel 304 has found use as a most versatile engineering material in many industrial applications. Recently, the Indian industries have developed high Mn stainless steels with low C and Ni contents and simultaneously introduced N and Cu in the system. Composition of some of the alloys which are prevalent in the market are given. Individually, the effect of Ni, C, Mn, N and Cu on various forms of corrosion is reasonably understood. However, it will be worthwhile to review the response of these alloys, containing all these elements, towards various forms of corrosion. The objective of this paper is preciously to do this

The Directorate General for Environment of the European Commission has launched a study on the 'Sectoral costs of environmental policy'. The overall aim of the study is to obtain a clearer picture of the impact of environmental policy in some of the industrial sectors most affected by environmental policy, taking into account the differences between sectors and Member States. Previous studies mainly focussed on the individual impact of one Directive, but in this study we will assess the cumulative costs attributable to the environmental policy in its entirety and attempt to identify synergies between individual policies. The project has the following main objectives: paint a clearer picture of the environmental costs for the selected industries; indicate the differences in costs between individual companies; indicate the differences in costs between Member States; demonstrate the drivers for environmental expenditures of the companies and differences between sectors and Member States; describe different types of environmental regulation (policy instruments) and their impact on environmental expenditures; evaluate the environmental performance of the industries and differences between companies/Member States; collect evidence for the impacts of environmental regulation (and associated costs) on the competitiveness of companies; and carry out an international comparison. The sectors selected are:oil supply chain; electricity production; steel industry; and textile and leather industry

2009-03-01
With India's transportation sector relying heavily on imported petroleum-based fuels, the Planning Commission of India and the Indian government recommended the increased use of blended biodiesel in transportation fleets, identifying Jatropha as a potentially important biomass feedstock. The Indian Oil Corporation and Indian Railways are collaborating to increase the use of biodiesel blends in Indian locomotives with blends of up to B20, aiming to reduce GHG emissions and decrease petroleum consumption. To help evaluate the potential for Jatropha-based biodiesel in achieving sustainability and energy security goals, this study examines the life cycle, net GHG emission, net energy ratio, and petroleum displacement impacts of integrating Jatropha-based biodiesel into locomotive operations in India. In addition, this study identifies the parameters that have the greatest impact on the sustainability of the system.
Lessons from the other side: what can we learn from the private sector?
Clarke, D
1999-01-01
Business has reacted in an impressive manner to increasing globalisation, short-term stock market pressure for performance, emerging industries and new technologies. While the private sector has become increasingly competitive, the public sector has not adopted this commercial rigour. Funding pressures on health services will continue, as will increasing consumer and staff demands and the blurring of public and private health care provision. As a result, there are lessons and techniques the public and private health sectors should learn from each other. I have drawn the issues that follow from my experience in the steel and food industries.

Electricity sector restructuring in India: an environmentally beneficial policy?
International Nuclear Information System (INIS)
Perkins, Richard
2005-01-01
It has been suggested that reforms to the electricity sector in developing countries encouraging the entry of independent power producers (IPPs) are likely to result in environmental improvements similar to those recently made in a number of developed economies. The present paper evaluates this claim by examining the experience of the Indian power sector. It finds that recent investments by IPPs have reduced the pollution-intensity of electricity generation in the country. Yet they have not brought the significant gains seen in countries such as the UK, nor are they likely to in the foreseeable future. This is largely a product of the nature and context of electricity sector reform in India which is less favourable to environmentally beneficial outcomes. Accordingly, the paper concludes by suggesting that the environmental benefits of restructuring are not automatic, but depend on the existence of an enabling structural, institutional and regulatory framework

The energy-utilization over a 10-year period (1994-2003) has been analysed for the South African industrial sector, which consumes more primary energy than any other sector of the economy. Four principal sub-sectors, namely iron and steel, chemical and petrochemical, mining and quarrying, and non-ferrous metals/non-metallic minerals were considered in this study. Primary-energy utilization data were used to calculate the weighted mean energy and exergy efficiencies for the sub-sectors and then overall values for the industrial sector were obtained. The results indicate that exergy efficiency is considerably lower than energy efficiency in all the sub-sectors, particularly in mining and quarrying processes, for which the values were approximately 83% and 16%, respectively. The performance of exergy utilization in the industrial sector can be improved by introducing various conservation strategies. Results from this study were compared with those for other countries

Full Text Available Privatization means establishing a new system based on the market mechanisms and consequently making a change, alteration in different aspects of economy and is a process in which the government can examine the possibility of transferring the duties and facilities to the private sector on any level and if necessary, exerts such transfer. On the other hand, exports in industry sector can be a noticeable point for the economic growth of any country. Enhancing the exports of the steel industry of the country can have a principal role in the economic pursuit of the country’s non-oil products. Such an enhancement brings about a positive effect in the efficiency of the stocks within the financial markets by developing the steel industry. Researchers of this field claim that privatization in the steel industry results in the further development of the steel stock market and exports. This paper presents a comprehensive survey on factors influencing on privatization of the firms in steel industry. The study has designed a questionnaire in Likert scale and distributed it among some experts who worked for Mobarakeh steel producer in Iran. Using principle component analysis, the survey has concluded that export activities were influenced the most by six major factors including creativity, technological limitation, opportunities and challenges, being up to date, customer orientation and financial sanction. Moreover, firm performance was influenced by two major factors of stakeholder’s satisfaction and organizational culture. Finally, two factors of rationalism and market orientation influenced the most on privatization.
Industrial Sickness in Indian Manufacturing
Falk, Rahel
2005-01-01
In India, the term ‘sick units’ refers to economically unviable firms which are kept alive ‘in the public interest’ by means of subsidies of various kinds. Since this practice is common, and large parts of the industrial sector are affected, this phenomenon is referred to as industrial sickness. As of March 2001, the Reserve Bank of India counted over a quarter of a million of sick units with outstanding credit worth more than a quarter of a trillion of Indian Rupees, i.e. about 1.2 percent o...

Occupational noise exposure and noise-induced hearing loss (NIHL) have been recognized as a problem among workers in Indian industries. The major industries in India are based on manufacturing. There are appreciable numbers of casting and forging units spread across the country. The objective of this study is to determine the prevalence of permanent hearing threshold shift among the workers engaged in Indian iron and steel small and medium enterprises (SMEs) and compared with control group subjects. As a part of hearing protection intervention, audiometric tests were conducted at low (250-1000 Hz), medium (1500-3000 Hz), and high (4000-8000 Hz) frequencies. The occurrence of hearing loss was determined based on hearing threshold levels with a low fence of 25 dB. Comparisons were made for hearing threshold at different frequencies between the exposed and control groups using Student's t test. ANOVA was used for the comparison of hearing threshold dB at different frequencies among occupation and year of experience. A P value workers engaged in various processes of casting and forging industry showed hearing loss in the noise-sensitive medium and higher frequencies. Occupation was significantly associated with NIHL, and hearing loss was particularly high among the workers of forging section. The analyses revealed a higher prevalence of significant hearing loss among the forging workers compared to the workers associated with other activities. The study shows alarming signals of NIHL, especially in forging workers. The occupational exposure to noise could be minimized by efficient control measures through engineering controls, administrative controls, and the use of personal protective devices. Applications of engineering and/or administrative controls are frequently not feasible in the developing countries for technical and financial reasons.

Full Text Available Can an industrial organisation simultaneously fulfil economic and social functions, that is to say successfully reconcile its own priorities of optimal resource utilisation and productive efficiency with the larger objectives of social justice defined for it by public authorities? This is the central question this paper whose compass is restricted to the 1980s asks, and seeks to answer on the basis of a study of locational and technology choices at a big public sector manufacturing firm, Indian Telephone Industries. It will show how decisions pertaining both to the implantation of new state-owned factories and the sourcing of technology were shaped not by an economic rationale but a political one where employment generation took precedence over all other considerations. This was a consequence, on the one hand, of the paradigm of state-initiated industrial development embraced by India after Independence in 1947 and which held out the promise of future prosperity for the population at large; on the other, of the mode of governance prevailing in public enterprises where state interventionism rhymed with the complete loss of autonomy for managements. The paper concludes by pointing out that however justified the redistributive goals allocated to public enterprises from the standpoint of improving living standards, they proved highly detrimental to their efficient working as well as onerous for the exchequer.

Full Text Available The author traces the history of formation of the Indian diaspora in the UK, evaluates the key trends that characterize the current state of diaspora. The article highlights the level of involvement and participation of diaspora in the evolution of the bilateral relations, as well as the influence of diaspora over home and foreign policy in the UK and India. The diaspora today is not just a unique vibrant connection between the two countries, it has also become a factor of influence over domestic, social and economic affairs in both the UK and India. There is a growing number of Indians among British statesmen and politicians. Indians occupy significant posts in various sectors in Britain, including business and finance. This contributes to strengthening of economic ties between the two countries, particularly important considering Britain’s forthcoming exit from the EU. As to internal political matters, though potential issues exist (those include, for instance, the possible transfer from India into Britain of problematic inter-caste relations, India’s criticism over unbalanced approach to teaching colonial history in British schools, the Indian diaspora due to its’ inherent tolerance and moderation generally plays a stabilizing role in the UK, especially on the background of radicalization of other ethnic communities. For the new India the diaspora today is not just an important source of financing, competences and know-how, it is also a significant lobbying and soft-power instrument. This article is part of a broader research, related to the contemporary relations between the United Kingdom and India. Indian diaspora in the UK is an integral part of the unique centuries-long history that connects the two countries. It is poised to remain a strong factor contributing to interdependence and cooperation between Britain and India in the XXI century.

The adversity of metallic corrosion is of growing concern to industrial engineers and scientists. Corrosion attacks metal surface and causes structural as well as direct and indirect economic losses. Multiple corrosion monitoring tools are available although those are time-consuming and costly. Due to the availability of image capturing devices in today's world, image based corrosion control technique is a unique innovation. By setting up stainless steel SS 304 and low carbon steel QD 1008 panels in distilled water, half-saturated sodium chloride and saturated sodium chloride solutions and subsequent RGB image analysis in Matlab, in this research, a simple and cost-effective corrosion measurement tool has identified and investigated. Additionally, the open circuit potential and electrochemical impedance spectroscopy results have been compared with RGB analysis to gratify the corrosion. Additionally, to understand the importance of ambiguity in crisis communication, the communication process between Union Carbide and Indian Government regarding the Bhopal incident in 1984 was analyzed.

The big worldwide demand for chrome-nickel alloy steels ('conventional steel') leads to the need for advanced materials for applications in different engineering systems that operate at high temperatures and in aggressive environmental conditions, favoring research and development in alternate alloys. In this technological race in search of these new materials, the FeMnAlC alloys ('new steels') have attracted attention for their excellent mechanical and tribological properties as well as for their good performance in corrosive-oxide environments, which make them similar to conventional steel. There are two important similarities between these two steels. First, an agent that causes the passive film to become stainless appears in both steels: chrome in the conventional steel, and aluminum in the FeMnAl alloy. The second similarity is that a stabilizing agent of the austenitic phase (FCC) appears in both, so that excellent mechanical properties can be obtained: nickel in the conventional steel, and manganese in the FeMnAl alloy. In certain sectors, such as aeronautics, conventional steel is rarely used because it is a very heavy material. This conventional steel is almost three times heavier that aluminum (7.85/2.7). Two advantages that the new FeMnAIC steels have compared to the conventional steels are that they are about 13% lighter in weight and they are less expensive. The FeMnAl also have excellent mechanical properties and good corrosion-oxidation resistance, which generates big expectations for their application in a broad scientific spectrum. This work reports the state of the information currently available about FeMnAlC alloys, comparing the mechanical and tribological behaviors of conventional alloy steels with chrome and nickel alloys, specifying the scopes of their application. A condition that favors the steels' fragility is the high speed of deformation and impact, where the FCC crystalline structure materials do not have a fragile ductile transition

Type-316 stainless steel (SS) was investigated as the cathode in galvanic couples in full-strength seawater from the Gulf of Mannar on the southeast coast of India. Tests were devised to examine the impact of SS cathodes on anode materials with or without the accrual of marine biofilms. Biofilmed SS cathodes significantly enhanced the rate of corrosion of nickel, causing noble shifts in the couple potentials. With mild steel and zinc as the anodes, calcareous deposits developed quite rapidly on the SS cathodes and led to a significant reduction of bacterial numbers. The calcareous deposits also caused substantial reduction of galvanic corrosion rates for mild steel, whereas there was no difference for zinc. The deposits were identified by XRD as essentially carbonates, oxides and hydroxides of calcium and magnesium. Potentiodynamic polarization performed on the actual couples after disconnection and equilibration provided reasonable interpretations of the galvanic corrosion trends. Data from this work suggest that a potential of about -0.70 V vs. saturated calomel electrode (SCE) should provide optimum protection of SS in warmer, full-strength seawater that supports the precipitation of calcareous deposits. The criterion commonly recommended for temperate conditions of lower water temperature and estuarine waters of lower alkalinity is -1.0 V (SCE).

Light water reactors were used with steel as nuclear fuel cladding from 1960 to 1980. The high performance proved that the use of low-carbon alloys could substitute the current zirconium alloys. Stainless steel is an alternative that can be used as cladding. The zirconium alloys replaced the steel. However, significant experiences in-pile occurred, in commercial units such as Haddam Neck, Indian Point, and Yankee experiences. Stainless Steel Types 347 and 348 can be used as cladding. An advantage of using Stainless Steel was evident in Fukushima when a large number of hydrogens was produced at high temperatures. The steel cladding does not eliminate the problem of accumulating free hydrogen, which can lead to a risk of explosion. In a boiling water reactor, environments easily exist for the attack of intergranular corrosion. The Stainless Steel alloys, Types 321, 347, and 348, are stabilized against attack by the addition of titanium, niobium, or tantalum. The steel Type 348 is composed of niobium, tantalum, and cobalt. Titanium preserves type 321, and niobium additions stabilize type 347. In recent years, research has increased on studying the effects of irradiation by fast neutrons. The impact of radiation includes changes in flow rate limits, deformation, and ductility. The irradiation can convert crystalline lattices into an amorphous structure. New proposals are emerging that suggest using a silicon carbide-based fuel rod cladding or iron-chromium-aluminum alloys. These materials can substitute the classic zirconium alloys. Once the steel Type 348 was chosen, the thermal and mechanical properties were coded in a library of functions. The fuel performance codes contain all features. A comparative analysis of the steel and zirconium alloys was made. The results demonstrate that the austenitic steel alloys are the viable candidates for substituting the zirconium alloys. (author)

This study examines the impacts felt downstream of carbon pricing and investments made in CO_2 abatement within the steel industry. Using the supply of steel to a passenger car as a case study, the effects of a steel price increase on cost structures and price at each step of the supply chain were assessed. Since the prices of emission allowances under the European Union Emissions Trading System fall well below those required to unlock investments in low-CO_2 production processes in the integrated steelmaking industry this paper seeks to pave the way for a discussion on complementary policy options. The results of the analysis suggest that passing on the compliance costs of the steel industry would have only marginal impacts on costs and prices for the end-use sectors (e.g., on the production cost or selling price of the passenger car). Under the assumptions made herein, at a carbon price of 100 €/tCO_2, the retail price of a mid-sized European passenger car would have to be increased by approximately 100–125 €/car (<0.5%) to cover the projected increases in steel production costs. - Highlights: • Examines impacts downstream of investments in CO_2 abatement in the steel industry. • Show how investing in low-CO_2 processes have marginal impacts in end-user stage. • Increase in the retail price of a mid-sized passenger car would be well below 1%. • Open up for complementary policies, financing mechanisms or new business models.

Effects of tungsten and tantalum contents on impact, tensile, low cycle fatigue and creep properties of Reduced Activation Ferritic–Martensitic (RAFM) steel were studied to develop India-specific RAFM steel. Four heats of the steel have been melted with tungsten and tantalum contents in the ranges 1–2 wt.% and 0.06–0.14 wt.% respectively. Increase in tungsten content increased the ductile-to-brittle transition temperature (DBTT), low cycle fatigue and creep strength of the steel, whereas the tensile strength was not changed significantly. Increase in tantalum content increased the DBTT and low cycle fatigue strength of the steel whereas the tensile and creep strength decreased. Detailed TEM investigations revealed enhanced microstructural stability of the steel against creep exposure on tungsten addition. The RAFM steel having 1.4 wt.% tungsten with 0.06 wt.% tantalum was found to possess optimum combination of impact, tensile, low cycle fatigue and creep properties and is considered for Indian-specific RAFM steel.

Full Text Available The need for microalloyed steels resistant to harsh environments in oil and gas fields, such as pre-salt which contain considerable amounts of hydrogen sulfide (H2 S and carbon dioxide (CO2 , requires that all sectors involved in petroleum industry know the factors that influence the processes of corrosion and failures by hydrogen in pipelines and components fabricated with microalloyed steels. This text was prepared from a collection of selected publications and research done at the Electrochemical Processes Laboratory of Metallurgical and Materials Engineering Department, Polytechnic School, São Paulo University. This document does not intend to be a complete or exhaustive review of the literature, but rather to address the main scientific and technological factors associated with failures by hydrogen in the presence of wet hydrogen sulfide (H2 S, particularly, when related to the Hydrogen Induced Cracking (HIC phenomenon. This complex phenomenon that involves several successive stages, HIC phenomena were discussed in terms of environmental and metallurgical variables. The HIC starts with the process of corrosion of steel, therefore must be considered the corrosive media (H2 S presence effect. Moreover, it is necessary to know the interactions of compounds present in the electrolyte with the metal surface, and how they affect the hydrogen adsorption and absorption into steel. The following stages are hydrogen diffusion, trapping and metal cracking, directly related to the chemical composition and the microstructure, factors that depend strongly on the manufacture of steel. The purpose of this paper is to provide the scientific information about the failures caused by hydrogen and challenge for the Oil and Gas Pipeline Industry.

India faces endemic electrical energy and peaking shortages. The Power Sector is plagued with mounting commercial losses due various inefficiencies, colossal commercial and technical losses and increasing subsidy burden on the states. These shortages have had a very detrimental effect on the overall economic growth of the country. In order to re-vitalise the sector and improve the techno-economic performance, the Government of India has initiated the reform process in 1991. This paper analyses the pre-reform era and identifies the key concerns which led to the initiation of the reforms. It also analyses the likely impact of the major policy and regulatory initiatives that have been undertaken since 1991 including the provisions of the new enactments which have come into force eventually in the form of The Electricity Act, 2003. This paper details out the key features of the Act and its likely impact on the Indian electricity industry in the emerging scenario. The paper also discusses major issues like power trading, role of regulator in the new regime, issue of open access, introduction of power markets and role of Appellate Tribunal for Electricity in harmonizing the orders of the various regulators.

Full Text Available Indian banking sector has completely changed. It has undergone much technological advancement that makes banking easy. Technological advancements are important but at the end what build customer satisfaction is proper management, employee behavior and customer relationship handling. Customer satisfaction is a sum of many variables that is many factors together leads to customer satisfaction. This modern electronic banking has completely changed the concept and functioning of banking system in India. Indian banking has moved from cash economy to cheque to and finally to the use of plastic cards. The customer satisfaction is dependent on customer awareness to a lot of extent. An unaware customer has less knowledge and therefore they cannot use the facilities completely even if they have it at their disposal. Customers prefer public sector banks when they are looking for trust and security and reliability. When it comes to speed, advancements and up gradation people shits from public sector banks to private sector banks. Customer gets satisfied only when they get quality service from the brand they are dealing with. This is very important for the marketers or the service providers as this leads to consumer satisfaction which benefits them and this brings loyalty to the brand enhancing the brand positioning. This research is important because new modern era has made people technology savvy they start their day with technology and end with technology therefore it is important to see the perception of users towards various factors of ATM. This research is conducted to see the highlighting factors that have direct impact on ATM services.

The paper starts from the observation that innovation and technical progress are only portrayed superficially in the predominant environmental economic top-down models, and that the assumption of perfect factor substitution does not correctly mirror actual production conditions in many energy-intensive production sectors. Bottom-up models, on the other hand, neglect macroeconomic interdependencies between the modelled sector and the general economy. This paper presents a new modelling approach: in an integrated bottom-up/top-down approach based on the example of crude steel production in Germany, it is demonstrated how technological progress can be portrayed as process-related and policy-induced and how the technology choice between limitational processes can be explicitly modelled and implemented in the econometric input-output model PANTA RHEI. The new modelling approach presented permits a process-specific analysis of the impacts of changed frame conditions, the effects of which on the choice of technology, on the one hand, and the technological progress on the other, can be described endogenous to the model. These features are demonstrated in a CO 2 tax simulation. Results show that policy-induced technological change is--besides a switch in production processes--the major source of CO 2 reduction for the steel sector
Reorganization of the power distribution sector in India

This paper presents the central issues for electricity-sector reform in India, as they grew out of the reform process that began in 1991, and within the context of the sector's organization, regulatory structure, and other institutional characteristics. The paper argues that India's current reform policies will not be sufficient to achieve reliable, efficient power because distribution reform has not been done. Undertaking distribution reform is a difficult path to tread because of the absence of global consensus on best practices and conflicting forces, both economic and political. The paper analyzes alternative institutional structures for reform in the distribution sector. The findings include that the objectives of coverage and efficiency may conflict, that economically efficient reorganization may be politically unachievable and that the small, municipally owned firm may be the best compromise. Since many Indian states are economically and politically diverse from each other, and include both large served and unserved areas, there is scope to vary the organizational structure depending on the state's situation. This paper provides a means to do so. The agenda for policymakers is to identify the situation in their respective states and choose a reorganization path that is the best compromise

The iron and steel industry is one of the major energy-consuming industries in China. Given the limited research on effective energy conservation in China's industrial sectors, this paper analyzes the total factor energy efficiency and the corresponding energy conservation potential of China's iron and steel industry using the excessive energy-input stochastic frontier model. The results show that there was an increasing trend in energy efficiency between 2005 and 2011 with an average energy efficiency of 0.699 and a cumulative energy conservation potential of 723.44 million tons of coal equivalent (Mtce). We further analyze the regional differences in energy efficiency and find that energy efficiency of Northeastern China is high while that of Central and Western China is low. Therefore, there is a concentration of energy conservation potential for the iron and steel industry in the Central and Western areas. In addition, we discover that inefficient factors are important for improving energy conservation. We find that the structural defect in the economic system is an important impediment to energy efficiency and economic restructuring is the key to improving energy efficiency. - Highlights: • A stochastic frontier model is adopted to analyze energy efficiency. • Industry concentration and ownership structure are main factors affecting the non-efficiency. • Energy efficiency of China's iron and steel industry shows a fluctuating increase. • Regional differences of energy efficiency are further analyzed. • Future policy for energy conservation in China's iron and steel sector is suggested

We study the relative influence of aerosols emitted from different sectors and geographical regions on aerosol loading in south Asia. Sectors contributing aerosol emissions include biofuel and fossil fuel combustion, open biomass burning, and natural sources. Geographical regions include India (the Indo-Gangetic plain, central India, south India, and northwest India), southeast Asia, east Asia, Africa-west Asia, and the rest of the world. Simulations of the Indian Ocean Experiment (INDOEX), from January to March 1999, are made in the general circulation model of Laboratoire de Météorologie Dynamique (LMD-ZT GCM) with emissions tagged by sector and geographical region. Anthropogenic emissions dominate (54-88%) the predicted aerosol optical depth (AOD) over all the receptor regions. Among the anthropogenic sectors, fossil fuel combustion has the largest overall influence on aerosol loading, primarily sulfate, with emissions from India (50-80%) and rest of the world significantly influencing surface concentrations and AOD. Biofuel combustion has a significant influence on both the surface and columnar black carbon (BC) in particular over the Indian subcontinent and Bay of Bengal with emissions largely from the Indian region (60-80%). Open biomass burning emissions influence organic matter (OM) significantly, and arise largely from Africa-west Asia. The emissions from Africa-west Asia affect the carbonaceous aerosols AOD in all receptor regions, with their largest influence (AOD-BC: 60%; and AOD-OM: 70%) over the Arabian Sea. Among Indian regions, the Indo-Gangetic Plain is the largest contributor to anthropogenic surface mass concentrations and AOD over the Bay of Bengal and India. Dust aerosols are contributed mainly through the long-range transport from Africa-west Asia over the receptor regions. Overall, the model estimates significant intercontinental incursion of aerosol, for example, BC, OM, and dust from Africa-west Asia and sulfate from distant regions (rest

Full Text Available Indian agriculture sector is a significant emitter of Green House Gas (GHG, which is projected to increase by 47% between 2011 and 2020. In response to this, India has committed itself to voluntarily reduce its emissions intensity (emissions per unit GDP between 20 to 25 percent below 2005 levels by 2020. This would require rapid and significant scaling up of mitigation efforts including the agriculture sector, which remains a challenge, as mitigation is not a priority in Indian agriculture. The study found out that in-spite of numerous mitigation technologies that are readily available for takeoff, the scale of adoption and deployment is far from sufficient to meet the emission targets set by the Government of India, mainly due to lack of financial incentives, capacity building of farmers, and an enabling policy at different levels. This study identified a suite of feasible interventions for promoting low carbon agriculture such as: low tillage systems as it has negative costs due to savings on tillage and fuel; introduction of superior livestock breeds to reduce numbers (especially unproductive cattle and increase yield; use of livestock wastes to produce energy for cooking and heating through bio-gas technology can not only reduce methane emission but also save electricity costs for the households and; introduction of carbon credits and exploration of domestic carbon markets. An enabling policy environment must be created for these interventions to take off.

The work objective is to conduct a greenhouse gas emission inventory of the industrial processes in Lebanon for the year 1994. The Lebanese industry has emitted 1924.063 Gg (1.924.063 tons) of Carbon dioxide CO 2 ; 0.0003 Gg (0.3 tons) of carbon monoxide CO; 0.01112 Gg of nitrogen oxide NO; 273.888 tons of non-methane volatile organic compounds and 3.382 Gg (3.382 tons) of sulphur dioxide SO 2 . The cement industry is the major source of CO 2 emissions among the industrial processes in Lebanon. The cement industry is responsible for 76.1% of the total emissions followed by the iron and steel industry which produces 21.68% of the total CO 2 emissions from industrial processes. The NMVOC emissions are mainly produced by the use of asphalt for road paving (98.5% of total emissions by industry) followed by the food and beverage industry (1.2%). The emissions of sulphur dioxide SO 2 come from three industrial sources: the first come from the production of sulphuric acid (69.9% of total industrial emissions), the second from the cement industry (26.4% of total industrial emissions) and the third from the iron and steel mills (3.7% of total industrial emissions). Figures are presented to show the percentage distribution of various industrial sources contributions to CO 2 , NMVOC and SO 2 emissions in Lebanon. Carbon monoxide CO emissions in the industrial sector are very small. The major source is iron and steel mills and the minor source is asphalt-roofing production

As the biggest iron and steel producer in the world and one of the highest CO2 emission sectors, China's iron and steel industry is undergoing a low-carbon transition accompanied by remarkable technological progress and investment adjustment, in response to the macroeconomic climate and policy intervention. Many drivers of the CO2 emissions of the iron and steel industry have been explored, but the relationships between CO2 abatement, investment and technological expenditure, and their connections with the economic growth and governmental policies in China, have not been conjointly and empirically examined. We proposed a concise conceptual model and an econometric model to investigate this crucial question. The results of regression, Granger causality test and impulse response analysis indicated that technological expenditure can significantly reduce CO2 emissions, and that investment expansion showed a negative impact on CO2 emission reduction. It was also argued with empirical evidence that a good economic situation favored CO2 abatement in China's iron and steel industry, while achieving CO2 emission reduction in this industrial sector did not necessarily threaten economic growth. This shed light on the dispute over balancing emission cutting and economic growth. Regarding the policy aspects, the year 2000 was found to be an important turning point for policy evolution and the development of the iron and steel industry in China. The subsequent command and control policies had a significant, positive effect on CO2 abatement. Copyright © 2014. Published by Elsevier B.V.

2001-01-01
The present paper examines the ultimate load carrying capacity of soil-steel structures taking into consideration the sequence of the developments of plastic hinges, their location, and their sustained plastic moment. Non-linear analysis has been conducted using a micro-computer program in which a structural model is applied with the soil replaced by normal and tangential springs acting at the nodal points of a polygon representing the conduit wall. A comparative study has been conducted for the parameters which affect the load carrying capacity of soil-steel structure, leading to the following conclusions: (1) the load carrying capacity of the composite structure is significantly affected by the shear stiffness (or friction) of the surrounding soil; (2) the conduit span may be used when calculating the buckling load rather than the local radius of the conduit wall; (3) circular arches with sector angle of less than 180 d eg have higher load carrying capacity than equivalent re-entrant arches, i.e. arches with sector angle of more than 180 d eg; (4) the buckling load of the conduit is slightly affected by the rigidity of the lower zone of the conduit wall; (5) eccentric application of the load has practically little effect on its load carrying capacity

A bottom-up methodological framework was developed and applied for the period 1985-2002, to selected manufacturing sub-sectors in Greece namely, food, beverages and tobacco, iron and steel, non-ferrous metals, non-metallic minerals and paper. Disaggregate physical data were aggregated according to their specific energy consumption (SEC) values and physical energy efficiency indicators were estimated. The Logarithmic Mean Divisia index method was also used and the effects of the production, structure and energy efficiency to changes in sub-sectoral manufacturing energy use were further assessed. Primary physical energy efficiency improved by 28% for the iron and steel and by 9% for the non-metallic minerals industries, compared to the base year 1990. For the food, beverages and tobacco and the paper sub-sectors, primary efficiency deteriorated by 20% and by 15%, respectively; finally electricity efficiency deteriorated by 7% for the non-ferrous metals. Sub-sectoral energy use is mainly driven by production output and energy efficiency changes. Sensitivity analysis showed that alternative SEC values do not influence the results whereas the selected base year is more critical for this analysis. Significant efficiency improvements refer to 'heavy' industry; 'light' industry needs further attention by energy policy to modernize its production plants and improve its efficiency

Full Text Available The interest in the field of arthroscopy is increasing globally and exponentially in the recent past, including in India. Clinicians interested in this area of super specialization have started publishing their research work in reputed journals in this field. The publication from Indian authors is contributed equally by both the teaching government institutions and nonteaching private hospital specialists. The contributions by the Indian teaching institutes have predominantly Indian authors only, whereas those from the private sectors usually have an association with the foreign authors in their research and publications. The publications with higher hierarchy and level of evidence (1 and 2 are associated with greater citations. In addition, the publications in high-impact, reputed journals attract more citations and therefore it is recommended that the “good” scientific research work should preferably be submitted to these journals to create greater impact and awareness about ones' research and publication.

Totare, Ninad P.; Pandit, Shubha
2010-01-01
In early 1990 the power sector in India required an initial set of reforms due to the scarcity of financial resources and its deteriorating technical and commercial efficiency. The Indian power sector is now going through a second stage of reforms in which restructuring of electric supply utilities has taken place. The Maharashtra State Electricity Board (MSEB) initiated reforms in 2005 by dividing the state electricity board into four separate companies. In this paper, the situations that led to the reform of the MSEB and the scope of the work required for an action plan initiated by the state electricity distribution company in the context of the proposed Key Performance Index are discussed. The post-reform status of the distribution company is analyzed with selected key parameters. The study also analyzes the electricity supply model implemented and the effect of a multi-year tariff plan as one of the key milestones of the tariff structure. The various new projects implemented by the distribution company to improve consumer services and the reform experiences of the other states are discussed, along with the future scope of the present reform process.

Numerical analysis of the cylindrical rigidity of the vertical steel tank shell
Chirkov, Sergey; Tarasenko, Alexander; Chepur, Petr
2017-10-01
The paper deals with the study of rigidity of a vertical steel cylindrical tank and its structural elements with the development of inhomogeneous subsidence in ANSYS software complex. The limiting case is considered in this paper: a complete absence of a base sector that varies along an arc of a circle. The subsidence zone is modeled by the parameter n. A finite-element model of vertical 20000 m3 steel tank has been created, taking into account all structural elements of tank metal structures, including the support ring, beam frame and roof sheets. Various combinations of vertical steel tank loading are analyzed. For operational loads, the most unfavorable combination is considered. Calculations were performed for the filled and emptied tank. Values of the maximum possible deformations of the outer contour of the bottom are obtained with the development of inhomogeneous base subsidence for the given tank size. The obtained parameters of intrinsic rigidity (deformability) of vertical steel tank can be used in the development of new regulatory and technical documentation for tanks.

Full Text Available Strengthening the influence of India in the Asian region and in the world requires for resorting of the modernization experience of this country, including the development of its energy sector. India today is among the top ten countries to generate electricity per capita. At the same time, both traditional sources of energy production coexist in India (using the muscular strength of man and animals with the conditions for the development of modern energy infrastructure through foreign investments. The article attempts to trace the main stages of the formation and development of energy industry in India; the modern state of energy is analyzed and plans for its development are considered. The research is based on a complex of traditional methods and approaches based on the principle of scientific objectivity and systemic method used in research in the framework of international relations and political science. For more than a century of history of the development of energy sector in India significant success has been achieved. Starting with the electrification of large cities and industrial enterprises due to foreign investments in the colonial period, India, after gaining the independence, set the task of developing its own infrastructure, electrifying the countryside and providing the industry with energy resources. The greatest progress in the development of electric power and nuclear energy was made. Indian economic growth will increase India’s energy needs and quadruple the demand for electricity over the next 25 years. For this, India needs to solve the problems of energy efficiency, energy complex management, lack of standards and energy imports, as well as actively introduce alternative energy sources and move to clean electricity (increased use of water resources and solar energy, which can be done through the development of Russian -Indian cooperation.

Energy bandwidth studies of U.S. manufacturing sectors can serve as foundational references in framing the range (or bandwidth) of potential energy savings opportunities. This bandwidth study examines energy consumption and potential energy savings opportunities in U.S. iron and steel manufacturing. The study relies on multiple sources to estimate the energy used in six individual process areas and select subareas, representing 82% of sector-wide energy consumption. Energy savings opportunities for individual processes and subareas are based on technologies currently in use or under development; the potential savings are then extrapolated to estimate sector-wide energy savings opportunity.

measures are available over time, which allows an estimation of technological change over a decade-long historical period. In particular, the report will describe new treatment of technological change in energy-climate modeling for this industry sector, i.e., assessing the changes in costs and energy-savings potentials via comparing 1994 and 2002 conservation supply curves. In this study, we compared the same set of mitigation measures for both 1994 and 2002 -- no additional mitigation measure for year 2002 was included due to unavailability of such data. Therefore, the estimated potentials in total energy savings and carbon reduction would most likely be more conservative for year 2002 in this study. Based upon the cost curves, the rate of change in the savings potential at a given cost can be evaluated and be used to estimate future rates of change that can be the input for energy-climate models. Through characterizing energy-efficiency technology costs and improvement potentials, we have developed and presented energy cost curves for energy efficiency measures applicable to the U.S. iron and steel industry for the years 1994 and 2002. The cost curves can change significantly under various scenarios: the baseline year, discount rate, energy intensity, production, industry structure (e.g., integrated versus secondary steel making and number of plants), efficiency (or mitigation) measures, share of iron and steel production to which the individual measures can be applied, and inclusion of other non-energy benefits. Inclusion of other non-energy benefits from implementing mitigation measures can reduce the costs of conserved energy significantly. In addition, costs of conserved energy (CCE) for individual mitigation measures increase with the increases in discount rates, resulting in a general increase in total cost of mitigation measures for implementation and operation with a higher discount rate. In 1994, integrated steel mills in the U.S. produced 55.

Haemophilus influenzae type b (Hib) vaccine has been available in India's private sector market since 1997. It was not until 14 December 2011 that the Government of India initiated the phased public sector introduction of a Hib (and DPT, diphtheria, pertussis, tetanus)-containing pentavalent vaccine. Our objective was to investigate the state-specific coverage and behaviour of Hib vaccine in India when it was available only in the private sector market but not in the public sector. This baseline information can act as a guide to determine how much coverage the public sector rollout of pentavalent vaccine (scheduled April 2015) will need to bear in order to achieve complete coverage. 16 of 29 states in India, 2009-2012. Retrospective descriptive secondary data analysis. (1) Annual sales of Hib vaccines, by volume, from private sector hospitals and retail pharmacies collected by IMS Health and (2) national household surveys. State-specific Hib vaccine coverage (%) and its associations with state-specific socioeconomic status. The overall private sector Hib vaccine coverage among the 2009-2012 birth cohort was low (4%) and varied widely among the studied Indian states (minimum 0.3%; maximum 4.6%). We found that private sector Hib vaccine coverage depends on urban areas with good access to the private sector, parent's purchasing capacity and private paediatricians' prescribing practices. Per capita gross domestic product is a key explanatory variable. The annual Hib vaccine uptake and the 2009-2012 coverage levels were several times higher in the capital/metropolitan cities than the rest of the state, suggesting inequity in access to Hib vaccine delivered by the private sector. If India has to achieve high and equitable Hib vaccine coverage levels, nationwide public sector introduction of the pentavalent vaccine is needed. However, the role of private sector in universal Hib vaccine coverage is undefined as yet but it should not be neglected as a useful complement to

Highlights: • Methodology for recycling of decommissioning steel was developed. • Four scenarios of recycling within nuclear and public sector were suggested. • Radiation impact assessment of suggested scenarios was performed. • Conditional clearance levels for analyzed radionuclides were derived. • Results imply that recycling of decommissioning steel can be feasible. -- Abstract: The decommissioning of nuclear power plants represents a complex process resulting in the generation of large amounts of waste materials, e.g. steel scrap containing various concentrations of radionuclides. Recycling some of these materials is highly desirable due to numerous reasons. Herein presented scenarios of recycling of radioactive steel within the nuclear as well as civil engineering industry are analyzed from the radiation protection point of view. An approach based on the dose constraints principle is chosen. The aim of the study is to derive conditional clearance levels (maximal specific mass activity of material allowing its recycling/clearance) for analyzed radionuclides ensuring that the detrimental impact on human health is kept on a negligible level. Determined conditional clearance levels, as the result of performed software calculations, are valid for the reuse of radioactive steel in four selected scenarios. Calculation results indicate that the increase of the amount of recyclable radioactive steel due to its reuse in specific applications may be feasible considering the radiation impact on the public and professionals. However, issues connected with public acceptance, technical difficulties and financing of potential realization are still open and they have to be examined in more detail

Hot cracking is a major problem in the welding of austenitic stainless steels, particularly the fully austenitic grades. A group of alloys of enhanced-nitrogen 316LN austenitic stainless steel is being developed for structural components of the Indian Fast Reactor programme. Studying the hot cracking behaviour of this nitrogen-enhanced austenitic stainless steel is an important consideration during welding, as this material solidifies without any residual delta ferrite in the primary austenitic mode. Nitrogen has potent effects on the solidification microstructure, and hence has a strong influence on the hot cracking behaviour. Different heats of this material were investigated, which included fully austenitic stainless steels containing 0.070.22 wt% nitrogen. Also, borated austenitic stainless steels, such as type 304B4, have been widely used in the nuclear applications primarily due to its higher neutron absorption efficiency. Weldability is a major concern for this alloy due to the formation of low melting eutectic phase that is enriched with iron, chromium, molybdenum and boron. Fully austenitic stainless steels are prone to hot cracking during welding in the absence of a small amount of delta ferrite, especially for compositions rich in elements like boron that increases the tendency to form low melting eutectics. Detailed weldability investigations were carried out on a grade 304B4 stainless steel containing 1.3 wt% boron. Among the many approaches that have been used to determine the hot cracking susceptibility of different alloys, Variable-Restraint (Varestraint) weld test and Hot Ductility (Gleeble) tests are commonly used to evaluate the weldability of austenitic alloys. Hence, investigations on these materials consisted of detailed metallurgical characterization and weldability studies that included studying both the fusion zone and liquation cracking susceptibility, using Varestraint tests at 0.254.0%, strain levels and Gleeble (thermo

Iron and steel manufacturing is among the most energy-intensive industries and accounts for the largest share, approximately 27 percent, of global carbon dioxide (CO2) emissions from the manufacturing sector. The ongoing increase in world steel demand means that this industry’s energy use and CO2 emissions continue to grow, so there is significant incentive to develop, commercialize and adopt emerging energy-efficiency and CO2 emissions-reduction technologies for steel production. Although studies from around the world have identified a wide range of energy-efficiency technologies applicable to the steel industry that have already been commercialized, information is limited and/or scattered regarding emerging or advanced energy-efficiency and low-carbon technologies that are not yet commercialized. This report consolidates available information on 56 emerging iron and steel industry technologies, with the intent of providing a well-structured database of information on these technologies for engineers, researchers, investors, steel companies, policy makers, and other interested parties. For each technology included, we provide information on energy savings and environmental and other benefits, costs, and commercialization status; we also identify references for more information.
Study on hydrogen assisted cracking susceptibility of HSLA steel by implant test

Full Text Available DMR-249A is an indigenously developed high strength low alloy steel for Indian ship building industry for making ship-hull and is extensively used in the construction of war ships and submarines. Welding electrodes conforming to SFA 5.5 AWS E8018 C1 has been indigenously developed for welding of this steel using shielded metal arc welding process. In the present study, susceptibility to hydrogen assisted cracking of DMR-249A steel welds made using this electrode has been assessed using implant test. Implant tests were conducted using this electrode at two different levels of diffusible hydrogen, measured using gas chromatography technique. It is observed that both the steel and the welding consumable are not susceptible to hydrogen assisted cracking even with a high diffusible hydrogen level of 9 mL/100g of weld metal. In implant tests, specimen did not fracture even after loading to stress levels higher than the yield strength of the base metal. The good resistance of this steel and the welding consumable, even with high levels of diffusible hydrogen, is attributed to absence of a susceptible microstructure in both the weld metal and heat affected zone. Hence, this study shows that, in the absence of a susceptible microstructure, hydrogen assisted cracking is unlikely to occur even if hydrogen level is high. It also confirms that in welding of DMR-249A with indigenously developed E8018 C1 electrode, hydrogen assisted cracking is not a concern and no preheating is required to avoid it during welding.

Green House Gas (GHG) emissions are the major cause of global warming and climate change. Carbon dioxide (CO2) is the main GHG emitted through human activities, at the household level, by burning fuels for cooking and lighting. As per the 2006 methodology of the Inter-governmental Panel on Climate Change (IPCC), the energy sector is divided into various sectors like electricity generation, transport, fugitive, 'other' sectors, etc. The 'other' sectors under energy include residential, commercial, agriculture and fisheries. Time series GHG emission estimates were prepared for the residential, commercial, agriculture and fisheries sectors in India, for the time period 2005 to 2014, to understand the historical emission changes in 'other' sector. Sectoral activity data, with respect to fuel consumption, were collected from various ministry reports like Indian Petroleum and Natural Gas Statistics, Energy Statistics, etc. The default emission factor(s) from IPCC 2006 were used to calculate the emissions for each activity and sector-wise CO2, CH4, N2O and CO2e emissions were compiled. It was observed that the residential sector generates the highest GHG emissions, followed by the agriculture/fisheries and commercial sector. In the residential sector, LPG, kerosene, and fuelwood are the major contributors of emissions, whereas diesel is the main contributor to the commercial, agriculture and fisheries sectors. CO2e emissions have been observed to rise at a cumulative annual growth rate of 0.6%, 9.11%, 7.94% and 5.26% for the residential, commercial, agriculture and fisheries sectors, respectively. In addition to the above, a comparative study of the sectoral inventories from the national inventories, published by Ministry of Environment, Forest and Climate Change, for 2007 and 2010 was also performed.

Globalisation is forcing many sectors to be more cost-effective due to the low manpower cost of developing countries. This, in combination with European trends of green production and reduction of emissions, enhances the necessity of advanced technologies to remain at the forefront of the market. It is precisely in this field where the Semisolid forming (SSF) exhibits a great potential. In Mondragon Unibertsitatea, it has been demonstrated the capability of producing sound components of 42CrMo4 and S48C steels by saving material, energy and attaining as hot forged properties. To make the process even more cost-effective, it has also been proved the capacity of SSF 44MnSiV6 microalloyed steel that enables the striking of the post processing heat treatment.

In this study, attenuation coefficients of two different stainless steel alloys (AISI 304 and AISI 310), which have a wide range of applications from home appliances to the automotive sector, and two different aluminum alloys (6013 and 5083), which have a high mechanical strength and a light weight structure and are used in many fields from aviation to military vehicles, has been determined. For this purpose, we used gamma spectrometer system with NaI(Tl) detector. In our measurements, we used Eu-152, Ra-226 and Co-60 as gamma ray sources. To narrow the beam of gamma rays, we designed the new steel based collimator. We also investigated the effect of using collimator. Obtained results were compared with the NIST XCOM values.
Critical pollutant emissions from the Indian telecom network
Sahu, S. K.; Schultz, M. G.; Beig, G.
2015-02-01
In recent years, India developed the world's 2nd largest telecom network based largely on mobile phone connections. The energy demand of the telecom sector especially in rural areas is mainly fueled by diesel combustion in mid-size generators due to either lack of grid power or unstable provision of electricity. This study quantifies the magnitude of emissions from the Indian telecom sector and presents a gridded inventory for the year 2011 with a spatial distribution derived on the provincial level including information on urban versus rural telecom installations. The estimated total NOx, PM, CO, BC, SO2, HC and CO2 emissions are found to be 295 ± 196 Gg/yr, 155 ± 108 Gg/yr, 61 ± 41 Gg/yr, 28 ± 18 Gg/yr, 114 ± 12 Gg/yr 19.50 ± 13 Gg/yr and 27.9 ± 12 million tons/yr, respectively. The future development of emissions from this sector will depend on the rate of electrification and possible market saturation. Air quality in rural areas of India could be improved by replacing diesel generators with renewable energy sources or electricity from the grid.

We outline the similarities between this case and those analyzed by Bunker and Ciccantell (2005, 2007 both in terms of the central role of generative sectors in raw materials and transport industries and how the creation and growth of these two industrial sectors shaped institutional patterns and the broader economic ascent of South Korea and East Asia. Even though South Korea has not and may never become a challenger for global hegemony, its rapid ascent has helped reshape East Asia and the capitalist world-economy. We use the model of generative sectors to analyze the critical industries that underlay and shaped South Koreas ascent from a low wage, light industry base to a world leader in electronics, automobiles, and other advanced industries.

Full Text Available The paper investigates the first and second orders moment transmission between gold and Indian industrial sectors with an application of portfolio design and hedging effectiveness using generalised VAR-ADCC-BVGARCH model. Our findings indicate unidirectional significant return spillover from gold to stock sectors. The negative values of estimated time varying conditional correlations are mainly observed during periods of market turbulence and crisis indicating the scope of portfolio diversification and hedging during these periods. We also estimate optimal weights, hedge ratios, and hedging effectiveness for the stock-gold portfolios. Our findings suggest that stock-gold portfolio provides better diversification benefits than stock portfolios.

This report is a valuable tool for members of the wind industry and policy makers alike to learn about the market opportunities and the legal and regulatory framework in India. In addition, it gives us insights into the challenges going forward and offers suggestions for overcoming remaining hurdles for wind power development. According to the outlook 65.2 GW of wind power could be installed in Indian by 2020, up from 13.1 GW at the end of 2010. This would attract around USD 10.4bn of annual investment to the sector, and create 170,000 'green collar' jobs in manufacturing, project development, installation, operation, maintenance, consulting etc. At the same time, it would save 174 tons of CO2 every year. By 2030, the installed capacity could reach as much as 160.7 GW. In order to fully exploit the indigenous energy source at its doorstep, the Indian government needs to address several challenges and barriers that are holding back development. This includes a national renewable energy law, incentives for repowering, and rapid up-scaling of grid infrastructure to transport increasing amounts of wind power to the demand centres. It highlights the key role wind power could play in fueling India's growing energy demand, by delivering substantial amounts of clean energy.

The CPR was towed horizontally at approximately 10m depth while the Shirase was steaming at about 14 knots across the Polar Front (PF. Mean total abundance of zooplankton for horizontal five nautical mile sample units was 168.1(SD : ±117.18 individuals with the maximum of 456 individuals. Zooplanktons were counted for 34 categories of species/taxa. Copepods occupied more than 90% of the total abundance in numbers. Oithona spp. was the most dominant group among copepods, representing 59% of the total zooplankton. Other numerically important categories were small-sized calanoids (copepodites and adults; 18.4%, and copepodites of Calanoides acutus and Calanus simillimus (8.2%. Latitudinal change of zooplankton abundance coincided with increasing/decreasing tends of temperature and salinity. Two different zooplankton assemblages were identified by cluster analysis and these assemblages seem to be closely related to different water characteristics, such as the of PF and areas of cold water masses. CPR is considered to be an ideal tool for long term monitoring of surface zooplankton communities.

This study reports the nitrogen uptake rate (using 15N tracer) of phytoplankton in surface waters of different frontal zones in the Indian sector of the Southern Ocean (SO) during austral summer of 2013. The investigated area encompasses four major frontal systems, i.e., the subtropical front (STF), subantarctic front (SAF), polar front-1 (PF1) and polar front-2 (PF2). Southward decrease of surface water temperature was observed, whereas surface salinity did not show any significant trend. Nutrient (NO3 - and SiO4 4-) concentrations increased southward from STF to PF; while ammonium (NH4 +), nitrite (NO2 -) and phosphate (PO4 3-) remained comparatively stable. Analysis of nutrient ratios indicated potential N-limited conditions at the STF and SAF but no such scenario was observed for PF. In terms of phytoplankton biomass, PF1 was found to be the most productive followed by SAF, whereas PF2 was the least productive region. Nitrate uptake rate increased with increasing latitude, as no systematic spatial variation was discerned for NH4 + and urea (CO(NH2)2). Linear relationship between nitrate and total N-uptake reveals that the studied area is capable of exporting up to 60% of the total production to the deep ocean if the environmental settings are favorable. Like N-uptake rates the f-ratio also increased towards PF region indicating comparatively higher new production in the PF than in the subtropics. The moderately high average f-ratio (0.53) indicates potentially near equal contributions by new production and regenerated production to the total productivity in the study area. Elevation in N-uptake rates with declining temperature suggests that the SO with its vast quantity of cool water could play an important role in drawing down the atmospheric CO2 through the "solubility pump".

India's majority of patients-including those living with diabetes-seek healthcare in the private sector through out-of-pocket (OOP) payments. We studied access to insulin in the private-sector market of Delhi state, India. A modified World Health Organization/Health Action International (WHO/HAI) standard survey to assess insulin availability and prices, and qualitative interviews with insulin retailers (pharmacists) and wholesalers to understand insulin market dynamics. In 40 pharmacy outlets analysed, mean availability of the human and analogue insulins on the 2013 Delhi essential medicine list was 44.4% and 13.1%, respectively. 82% of pharmacies had domestically manufactured human insulin phials, primarily was made in India under licence to overseas pharmaceutical companies. Analogue insulin was only in cartridge and pen forms that were 4.42 and 5.81 times, respectively, the price of human insulin phials. Domestically manufactured human phial and cartridge insulin (produced for foreign and Indian companies) was less expensive than their imported counterparts. The lowest paid unskilled government worker in Delhi would work about 1.5 and 8.6 days, respectively, to be able to pay OOP for a monthly supply of human phial and analogue cartridge insulin. Interviews suggest that the Delhi insulin market is dominated by a few multinational companies that import and/or license in-country production. Several factors influence insulin uptake by patients, including doctor's prescribing preference. Wholesalers have negative perceptions about domestic insulin manufacturing. The Delhi insulin market is an oligopoly with limited market competition. Increasing competition from Indian companies is going to require some additional policies, not presently in place. As more Indian companies produce biosimilars, brand substitution policies are needed to be able to benefit from market competition.

Yeonbae, Kim; Worrell, E.
2002-01-01
In this paper, we present an in-depth decomposition analysis of trends in CO 2 emissions in the iron and steel industry using physical indicators. Physical indicators allow a detailed analysis of intra- sectoral trends, in contrast to the mostly used monetary indicators. Detailed decomposition analysis makes it possible to link developments in energy intensity to technology change and (indirectly) to policy. We present an analysis for the iron and steel industry in seven countries, i.e. Brazil, China, India (developing countries), Mexico and South Korea (newly industrialized countries) and the United States (industrialized country). We found substantial differences in energy efficiency among these countries. In most countries the increased (or decreased) production was the main contributor to changes in CO 2 emissions, while energy-efficiency was the main factor reducing emission intensities of steel production in almost all countries. Changes in power generation contributed to a reduction of specific emissions in the case of South Korea only. (Author)

In recent years, the food science sector has gained importance since the society is focusing on high-quality and safety foods. With a specific end goal to meet this societal need, the research and development organizations in India have adopted innovative technical and research processes, which gave more accentuation on intellectual assessment in food processing industry. The global Intellectual Property regime in food science sector had witnessed an increment in the number of patents filed and granted during 2006-2010. Ever since there has been a gradual increase in the number of patents applied mainly in food processing industries by research organizations related to food sciences, for example, those working under the aegis of ICAR and CSIR in India. In this study, a review has been done on the intellectual assets generated by ICAR and other national research organizations in India, in the food science sector. Emphasis has been given on the global relevance of these assets, modes of IP protection and technology transfer mechanisms followed by different public and private organizations.

The microbial corrosion behavior of three important steels (carbon steel, stainless steel, and Corten steel) was investigated in semi petroleum medium. This work was done in modified nutrient broth (2 g nutrient broth in 1 L oily wastewater) in the presence of Pseudomonas aeruginosa and mixed culture (as a biotic media) and an abiotic medium for 2 weeks. The behavior of corrosion was analyzed by spectrophotometric and electrochemical methods and at the end was confirmed by scanning electron microscopy. The results show that the degree of corrosion of Corten steel in mixed culture, unlike carbon steel and stainless steel, is less than P. aeruginosa inoculated medium because some bacteria affect Corten steel less than other steels. According to the experiments, carbon steel had less resistance than Corten steel and stainless steel. Furthermore, biofilm inhibits separated particles of those steels to spread to the medium; in other words, particles get trapped between biofilm and steel.
Changes in carbon intensity in China's industrial sector: Decomposition and attribution analysis

The industrial sector accounts for 70% of the total energy-related CO_2 emissions in China. To gain a better understanding of the changes in carbon intensity in China's industrial sector, this study first utilized logarithmic mean Divisia index (LMDI) decomposition analysis to disentangle the carbon intensity into three influencing factors, including the emission coefficient effect, the energy intensity effect, and the structure effect. Then, the analysis was furthered to explore the contributions of individual industrial sub-sectors to each factor by using an extension of the decomposition method proposed in Choi and Ang (2012). The results indicate that from 1996 to 2012, the energy intensity effect was the dominant factor in reducing carbon intensity, of which chemicals, iron and steel, metal and machinery, and cement and ceramics were the most representative sub-sectors. The structure effect did not show a strong impact on carbon intensity. The emission coefficient effect gradually increased the carbon intensity, mainly due to the expansion of electricity consumption, particularly in the metal and machinery and chemicals sub-sectors. The findings suggest that differentiated policies and measures should be considered for various industrial sub-sectors to maximize the energy efficiency potential. Moreover, readjusting the industrial structure and promoting clean and renewable energy is also urgently required to further reduce carbon intensity in China's industrial sector. - Highlights: • The study analyzed the changes in carbon intensity in China's industrial sector. • An extension of the Divisia index decomposition methodology was utilized. • Energy efficiency improvement was the dominant factor reducing carbon intensity. • The sub-sector contributions to the energy efficiency improvement varied markedly. • Emission coefficient growth can be mainly due to the expansion of electricity.

Life Cycle Assessment Comparing the Use of Jatropha Biodiesel in the Indian Road and Rail Sectors
Energy Technology Data Exchange (ETDEWEB)
Whitaker, M.; Heath, G.
2010-05-01
This life cycle assessment of Jatropha biodiesel production and use evaluates the net greenhouse gas (GHG) emission (not considering land-use change), net energy value (NEV), and net petroleum consumption impacts of substituting Jatropha biodiesel for conventional petroleum diesel in India. Several blends of biodiesel with petroleum diesel are evaluated for the rail freight, rail passenger, road freight, and road-passenger transport sectors that currently rely heavily on petroleum diesel. For the base case, Jatropha cultivation, processing, and use conditions that were analyzed, the use of B20 results in a net reduction in GHG emissions and petroleum consumption of 14% and 17%, respectively, and a NEV increase of 58% compared with the use of 100% petroleum diesel. While the road-passenger transport sector provides the greatest sustainability benefits per 1000 gross tonne kilometers, the road freight sector eventually provides the greatest absolute benefits owing to substantially higher projected utilization by year 2020. Nevertheless, introduction of biodiesel to the rail sector might present the fewest logistic and capital expenditure challenges in the near term. Sensitivity analyses confirmed that the sustainability benefits are maintained under multiple plausible cultivation, processing, and distribution scenarios. However, the sustainability of any individual Jatropha plantation will depend on site-specific conditions.
Paleoceanographic Changes during the Past 95000 Years from the Indian Sector of the Southern Ocean

2012-12-01
High-resolution planktic/benthic foraminiferal stable isotope and mean sortable silt records in a sediment core (SK200/22a) from the sub-Antarctic regime of the Indian sector of Southern Ocean depict the variations in surface and deep water hydrography during the past 95,000 years. The δ18O records of shallow- and deep-dwelling planktonic foraminiferal species (Neogloboquadrina pachyderma, Globigerina bulloides and Globorotalia inflata), primarily reflects the changes in upper water column characteristics. The δ18O records revealed the presence of the Antarctic Cold Reversal and the timing of the variability in major surface warming events appears in phase with the Antarctic temperature variations at the millennial time scale. Comparison between the proxies of sea surface conditions like planktonic δ18O and productivity proxies like carbonate and biogenic opal content in the core indicate that millennial scale sea surface warming fluctuated with productivity. The marine isotopic stage (MIS) 1 and MIS2 are characterized by near constant variations in mean sortable silt values, negating any significant changes in the deep water flow during these periods. The MIS 3 - MIS 5 periods were characterized by a general increase in mean sortable silt value, suggesting a strengthening of bottom-current activity that triggered winnowing at these periods. This is supported by the low δ13C records of epibenthic Cibicidoides wuellerstorfi during the glacials and some parts of MIS3 and MIS 5, confirming older nutrient-rich and poorly ventilated southern sourced deep waters at these periods. The termination I is marked by decrease in flow speed and an increase in the C. wuellerstorfi δ13C values. Comparison of mean sortable silt and C. wuellerstorfi δ13C record with the Antarctic ice core records reveal that pulses of reduced bottom water flow of Circumpolar Deep Water/North Atlantic Deep Water are synchronous with the Antarctic warming events.

Increasing concerns on non-sustainable energy use and climate change spur a growing research interest in energy efficiency potentials in various critical areas such as industrial production. This paper focuses on learning curve aspects of energy efficiency measures in the U.S iron and steel sector. A number of early-stage efficient technologies (i.e., emerging or demonstration technologies) are technically feasible and have the potential to make a significant contribution to energy saving and CO2 emissions reduction, but fall short economically to be included. However, they may also have the cost effective potential for significant cost reduction and/or performance improvement in the future under learning effects such as ‘learning-by-doing’. The investigation is carried out using ISEEM, a technology oriented, linear optimization model. We investigated how steel demand is balanced with/without the availability learning curve, compared to a Reference scenario. The retrofit (or investment in some cases) costs of energy efficient technologies decline in the scenario where learning curve is applied. The analysis also addresses market penetration of energy efficient technologies, energy saving, and CO2 emissions in the U.S. iron and steel sector with/without learning impact. Accordingly, the study helps those who use energy models better manage the price barriers preventing unrealistic diffusion of energy-efficiency technologies, better understand the market and learning system involved, predict future achievable learning rates more accurately, and project future savings via energy-efficiency technologies with presence of learning. We conclude from our analysis that, most of the existing energy efficiency technologies that are currently used in the U.S. iron and steel sector are cost effective. Penetration levels increases through the years, even though there is no price reduction. However, demonstration technologies are not economically

The sliding friction and wear behaviour of different steel qualities were investigated with and without lubrication conditions. Steel qualities tested are normally used in the overhead conveyor system of many industrial fields, like the automotive sector. Sliding wear tests have been conducted by means of a pin-on-disk machine. A 100Cr6 steel similar to that used within the overhead conveyor trolleys has been employed as a pin. Friction coefficient values obtained under lubrication conditions were three times smaller than those obtained without lubrication. The mechanism that controls wear behaviour under lubrication conditions is an abrasive one and the wear values obtained are almost worthless. On the other hand, mechanism controlling wear during non lubrication tests, was a combination of abrasion and adhesion. (Author) 20 refs
Understanding Rossby wave trains forced by the Indian Ocean Dipole
McIntosh, Peter C.; Hendon, Harry H.
2018-04-01
Convective variations over the tropical Indian Ocean associated with ENSO and the Indian Ocean Dipole force a Rossby wave train that appears to emanate poleward and eastward to the south of Australia and which causes climate variations across southern Australia and more generally throughout the Southern Hemisphere extratropics. However, during austral winter, the subtropical jet that extends from the eastern Indian Ocean into the western Pacific at Australian latitudes should effectively prohibit continuous propagation of a stationary Rossby wave from the tropics into the extratropics because the meridional gradient of mean absolute vorticity goes to zero on its poleward flank. The observed wave train indeed exhibits strong convergence of wave activity flux upon encountering this region of vanishing vorticity gradient and with some indication of reflection back into the tropics, indicating the continuous propagation of the stationary Rossby wave train from low to high latitudes is inhibited across the south of Australia. However, another Rossby wave train appears to emanate upstream of Australia on the poleward side of the subtropical jet and propagates eastward along the waveguide of the eddy-driven (sub-polar) jet into the Pacific sector of the Southern Ocean. This combination of evanescent wave train from the tropics and eastward propagating wave train emanating from higher latitudes upstream of Australia gives the appearance of a continuous Rossby wave train propagating from the tropical Indian Ocean into higher southern latitudes. The extratropical Rossby wave source on the poleward side of the subtropical jet stems from induced changes in transient eddy activity in the main storm track of the Southern Hemisphere. During austral spring, when the subtropical jet weakens, the Rossby wave train emanating from Indian Ocean convection is explained more traditionally by direct dispersion from divergence forcing at low latitudes.

The objectives of this study are to: Give an overview of the current discussion concerning competition distortion in relation to climate policy; Describe results from some studies estimating the actual competition situation for selected activities; Describe what sector agreement models are suggested/ discussed by EU; Describe what sectors are most interesting to target with a sector agreement from a Swedish point of view; Analyse what parameters are important for reducing competition distortion for Swedish Industry. Two studies, for the United Kingdom and Germany, have recently assessed the potential cost impact for different industrial sectors of CO{sub 2}-prices due to the EU ETS. The sectors with high potential impact, with a maximum value at stake larger than 10%, are in the United Kingdom Lime and cement, Basic iron and steel, Starches, Refined petroleum, Fertilizers and Nitrogen compounds and Aluminium. In Germany: Cement and lime, Fertilizers and nitrogen compounds, Basic iron and steel, Aluminium, Paper and board, Other basic inorganic compounds and Coke, refined petroleum and nuclear fuels. Ex-ante studies of the impacts of competitiveness and carbon leakage due to the EU ETS fail to find actual impacts. However, that does not mean that there will be no impact in the future, which hold changes both in the EU ETS (method for allowance allocation, allowance prices etc) and possibly also other important circumstances. In this study, based on official Swedish statistics, the maximum value a stake has been calculated for 52 Swedish sectors. Seven sectors have a maximum value a stake of more than 4%: Coke and refined petroleum (21%), Pulp and paper (11%), Basic metals (10%), Non-metallic mineral (9%), Metal ore mines (6%), Air transport (5%) and Electricity, gas and heat (4%). If Air transport and Electricity, gas and heat are omitted, the five remaining sectors account for 22% of Sweden's carbon emissions. In late 2008, the EU proposed three types of

Full Text Available n 2008 the world economy landed itself in the midst of the most severe financial recession which originated in the developed countries and spread to the developing countries which were hit hard through capital reversals, rising borrowing costs, collapsing world trade and commodity prices, and subsiding remittances. India’s engagement with the global economy became deeper from the 1990s and this made it inevitable to be affected by the global meltdown. This paper attempts to analyze the impact of the global recession on the external sector of the Indian economy. A pre and post recession (2008 analysis is undertaken to see the impact on trade, capital flows, exchange rates and foreign exchange reserves and external debt. The analysis reveals that while India was adversely impacted due to the slowdown in trade, capital flows and outsourcing; the impact has not been as much as in many other Asian economies. The capital flows were soon back, as India seemed like a save haven for funds with reasonable growth and interest rates. The Indian banking and regulatory system has been credited for following prudential norms and India’s huge domestic market and fiscal stimulus have got the economy almost back on track with growth rates looking up again.

The present thesis is about the reforms in the electricity sector in India, and more specifically about those in the State Electricity Boards (SEBs), organisations responsible for generation, transmission and distribution of electricity at the level of each of the States of India. The thesis is interested in practical questions of industrial economy such as: what is the impact of de-integration on the functioning of the SEBs?, impact of the creation of regulatory committees?, of privatisation?. Going beyond the critical analysis of the proposed reforms, the thesis also puts forward certain practical propositions as regards the way of reforming the SEBs. The thesis is divided in two parts (of four chapters each). The first part analyses and characterizes the functioning of a SEB. It presents practical description of the organisational characteristics, but also of their linking to the decision making mechanisms at work. On the theoretical plane, it settles the debate on the validity of the analytical concept of soft budget constraint for a SEB, and specifies the modalities of an analysis in terms of property rights, as well as the pertinence of several concepts derived from that of cost. The second part deals with the ongoing reforms and those to be implemented. It defines the concept of enterprising and proposes a critical discussion of the ongoing reforms, in the light of the normative criterion of enterprisation. It distinguishes conceptually and in the practical analysis, the 'structural' reforms (corporatisation, de-integration, and setting up of regulatory commissions) on the one hand and the questions of privatisation on the other. It proposes a model explaining the 'trade off' between public enterprisation and rapid privatisation. The first chapter situates the SEBs in the Indian power sector, shows the limit of the analyses in terms of lack of funds or political interference. Chapter 2 makes a critical presentation of the various tools offered to the

The Indian cement industry is one of the most efficient in the world. Its efforts to reduce its carbon footprint by adopting the best available technologies and environmental practices are reflected in the achievement of reducing total CO2 emissions to an industrial average of 0.719 tCO2/t cement in 2010 from a substantially higher level of 1.12 tCO2/t cement in 1996. However, because the manufacturing process relies on the burning of limestone, it still produced 137 MtCO2 in 2010 – approximately 7% of India’s total man-made CO2 emissions. Yet opportunity for improvement exists, particularly in relation to five key levers that can contribute to emissions reductions: alternative fuel and raw materials; energy efficiency; clinker substitution; waste heat recovery and newer technologies. This roadmap sets out one pathway by which the Indian cement industry can reach its targets to improve energy efficiency and reduce CO2 emissions by 2050, thereby laying the foundation for low-carbon growth in the years beyond. The Technology Roadmap: Low-Carbon Technology for the Indian Cement Industry builds on the global IEA technology roadmap for the cement sector developed by the IEA and the World Business Council for Sustainable Development’s Cement Sustainability Initiative. It outlines a possible transition path for the Indian cement industry to reduce its direct CO2 emissions intensity to 0.35 tCO2/t cement and support the global goal of halving CO2 emissions by 2050.

Decommissioning process and related management of generated radioactive materials during this process became important topics during last several years because of continuously increasing number of nuclear power plant approaching the end of their lifetime. The very low level radioactive waste category includes considerable amount of materials arising from decommissioning. In line with international incentives of optimization of the waste management process, alternative concepts of recycling and reuse of materials are considered. One of these concepts of such optimization is the conditional release of materials with their subsequent recycling and reuse in industrial or nuclear sector. This paper is devoted to an option of recycling and reuse of conditionally released steel in industrial sector, specifically in motorway tunnel constructions. It is assumed that very low level radioactive steel would be released and reused in form of steel reinforcing components, such as steel nets and bars, assembled in primary and secondary lining of motorway tunnel. Assessment of exposure pathways relevant for construction, operation and post-operation period was performed. The computational tool VISIPLAN 3D ALARA was used for calculation of external individual effective dose for personnel constructing the tunnel and for members of the public driving through already built motorway tunnel. The simulation software GOLDSIM was used for the assessment of internal exposure pathways. GOLDSIM environment enables modelling of degradation processes and transport of radionuclides through unsaturated and saturated zone of subsoil. There are international recommendations available for the concept of release of radioactive materials into the environment derived from the principles that the individual effective dose received by critical individual must not exceed some tens of microSv/yr. Dose limits 10 microSv/yr or 50 microSv/yr considering specific conditions are stated in Slovak legislation

This paper on overview of Indian activities on fusion reactor materials describes in brief the efforts India has made to develop materials for the first wall of a tokamak, its blanket and superconducting magnet coils. Through a systematic and scientific approach, India has developed and commercially produced reduced activation ferritic/martensitic (RAFM) steel that is comparable to Eurofer 97. Powder of low activation ferritic/martensitic oxide dispersion strengthened steel with characteristics desired for its application in the first wall of a tokamak has been produced on the laboratory scale. V–4Cr–4Ti alloy was also prepared in the laboratory, and kinetics of hydrogen absorption in this was investigated. Cu–1 wt%Cr–0.1 wt%Zr – an alloy meant for use as heat transfer elements for hypervapotrons and heat sink for the first wall – was developed and characterized in detail for its aging behavior. The role of addition of a small quantity of Zr in its improved fatigue performance was delineated, and its diffusion bonding with both W and stainless steel was achieved using Ni as an interlayer. The alloy was produced in large quantities and used for manufacturing both the heat transfer elements and components for the International Thermonuclear Experimental Reactor (ITER). India has proposed to install and test a lead–lithium cooled ceramic breeder test blanket module (LLCB-TBM) at ITER. To meet this objective, efforts have been made to produce and characterize Li{sub 2}TiO{sub 3} pebbles, and also improve the thermal conductivity of packed beds of these pebbles. Liquid metal loops have been set up and corrosion behavior of RAFM steel in flowing Pb–Li eutectic has been studied in the presence as well as absence of magnetic fields. To prevent permeation of tritium and reduce the magneto-hydro-dynamic drag, processes have been developed for coating alumina on RAFM steel. Apart from these activities, different approaches being attempted to make the U

Iron and steel industry is the most energy intensive industrial sector in Iran. Long time subsidized energy has led to low energy efficiency in this industry. The sudden subsidy reform of energy prices in Iran is expected to have a great impact on steel production and energy consumption. A system dynamics model is presented in this paper to analyze steel demand, production and energy consumption in an integrated framework. A co-flow structure is used to show how subsidy reform affects energy consumption in the long run. The main focus of this paper is on direct and indirect natural gas consumption in the steel industry. Scrap based Electric Arc Furnace technology has been evaluated as an energy efficient way for steel making. The energy consumption in steel industry is estimated under various steel production and export scenarios while taking into account new energy prices to see the outlook of possible energy demand in steel industry over next 20 years. For example it is shown that under reference production scenario, potential reduction in gas consumption forced by complete removal of energy subsidy and utilizing scrap could lead to 85 billion cubic meters of gas saving over the next 20 years. -- Highlights: ► We develop a system dynamics model to analyze steel demand, production and energy consumption in Iran. ► Various scenarios have been simulated to see the energy demand of Iranian steel industry over the next 20 years. ► A co-flow structure is used to show how subsidy reform would affect energy consumption in the long run. ► A co-flow structure has been built into the SD model to formulate consumers' behavior in response to energy prices. ► Scrap based Electric Arc Furnace technology has been evaluated as an energy efficient alternative for steel making.

Most of the psychiatry practice in India is guided by the western concepts of mental health and illness, which have largely ignored the role of religion, family, eastern philosophy, and medicine in understanding and managing the psychiatric disorders. India comprises of diverse cultures, languages, ethnicities, and religious affiliations. However, besides these diversities, there are certain commonalities, which include Hinduism as a religion which is spread across the country, the traditional family system, ancient Indian system of medicine and emphasis on use of traditional methods like Yoga and Meditation for controlling mind. This article discusses as to how mind and mental health are understood from the point of view of Hinduism, Indian traditions and Indian systems of medicine. Further, the article focuses on as to how these Indian concepts can be incorporated in the practice of contemporary psychiatry. PMID:23858244

High-power Laser Welding of Thick Steel-aluminum Dissimilar Joints
Lahdo, Rabi; Springer, André; Pfeifer, Ronny; Kaierle, Stefan; Overmeyer, Ludger
According to the Intergovernmental Panel on Climate Change (IPCC), a worldwide reduction of CO2-emissions is indispensable to avoid global warming. Besides the automotive sector, lightweight construction is also of high interest for the maritime industry in order to minimize CO2-emissions. Using aluminum, the weight of ships can be reduced, ensuring lower fuel consumption. Therefore, hybrid joints of steel and aluminum are of great interest to the maritime industry. In order to provide an efficient lap joining process, high-power laser welding of thick steel plates (S355, t = 5 mm) and aluminum plates (EN AW-6082, t = 8 mm) is investigated. As the weld seam quality greatly depends on the amount of intermetallic phases within the joint, optimized process parameters and control are crucial. Using high-power laser welding, a tensile strength of 10 kN was achieved. Based on metallographic analysis, hardness tests, and tensile tests the potential of this joining method is presented.

Greenhouse gas emissions emerged in the last decade as a key environmental problem on the political agenda. The most important greenhouse gas is carbon dioxide (CO 2 ). This gas results from the combustion of fossil fuels (natural gas, oil and coal). As a consequence, greenhouse gas emission reduction is closely related to energy policies. Even a stabilization of the atmospheric CO 2 concentrations at a level of 750 ppm (parts per million), more than twice the current level, implies a reduction of global emissions by 50% in the next century. The world population will simultaneously double and the capita energy consumption will increase. As a consequence, the Western industrialized countries will have to reduce their per capita emissions by more than a factor four. Such a policy goal will significantly affect the future industrial production structure. Approximately 4% of the global CO 2 emissions can be attributed to the production of iron and steel. This sector is the most important industrial source of CO 2 . The case study for the iron and steel industry will be discussed in this paper in order to illustrate the impact of significant CO 2 emission mitigation on the industry. The goal is to show the consequences of CO 2 policies for R and D planning and investment decisions. The notion that the iron and steel industry will be affected by CO 2 policies is not new; a number of studies have addressed this issue before. These studies have compared steel production technologies and emission reduction options within the iron and steel production sector. In this paper, the emission reduction in the iron and steel industry is analyzed within the framework of the changing (inter-)national energy and materials system configuration. This includes all production, conversion and consumption processes. The impact of CO 2 policies on the optimal choice of steel production technologies and on the competitiveness of steel compared to other materials will be discussed. This paper

Highlights: • Generation of first set of experimental data related to LCF performance of the commercial heat of IN-RAFM steel. • Analysis of cyclic behavior from the perspective of both design and material characteristics. • Various correction factors to account for various plastic strain accumulations, change in Poisson’s ratio and asymmetry of loadings. • Low cycle fatigue design parameters and correction factor values were comparable with P91 steel as reported in RCC-MR design code. - Abstract: The objective of the present paper is to provide first hand experimental data and analysis on the low cycle fatigue (LCF) performance of a commercial heat of Indian reduced activation ferritic-martensitic (IN-RAFM) steel. Since this material is not yet codified in RCC-MR, cyclic properties were generated for the design of the structural material of the Test Blanket Modules (TBM) made of RAFM steel. Hence, as a part of the material development program, LCF experiments were conducted on IN-RAFM steel obtained in the normalized and tempered condition. Total axial strain controlled experiments were performed in air by employing strain amplitudes ranging from ±0.25 to ±1.0% and at temperatures of 300, 673, 723, 823, and 873 K and a nominal strain rate, 3 × 10{sup −3} s{sup −1}. In the present work, various cyclic parameters that are useful for the design oriented fatigue analysis are derived as per the systematic procedure given in the RCC-MR design code. The physical significance of each design parameter such as elasto-plastic corrections based on Neuber analysis has been explained and correlated with the material behavior such as the cyclic softening nature of the RAFM steel.

Various tests have been conducted on the steel bars used in the construction of civil works in Almeria (Spain) during the period 18 January 2000-7May 2001, with the aim of mechanically characterizing the different types of steel (weldable; B400S, B500S and ductile weldable: B400SD) to determine whether there is a technical reason for the increase in the use of ductile weldable steel. For this, we have used a hydraulic machine to break by traction all the test samples that arrived to the laboratory, following the specifications of the UNE 7474-1:1992 and the UNE 7474-2:1992. The results indicate that only in 86% of the cases does the steel B400SD satisfy the limits specified by the UNE 36065:1999-EX, as opposed to 95 and 94% of the B400S and B500S steels. In addition the ductile weldable steel registered mean values lower than those of B400S. This findings disagrees with expectations set by the specifications. (Author) 6 refs.

This study was conducted to compare the laser weldability of boron steel and hot-stamped steel. In general, boron steel is used in the hot-stamping process. Hot-stamping is a method for simultaneously forming and cooling boron steel in a press die after heating it to the austenitizing temperature. Hot-stamped steel has a strength of 1500 MPa or more. Thus, in this study, the laser weldability of boron steel and that of hot-stamped steel were investigated and compared. A continuous wave disk laser was used to produce butt and lap joints. In the butt welding, the critical cooling speed at which full penetration was obtained in the hot-stamped steel was lower than that of boron steel. In the lap welding, the joint widths were similar regardless of the welding speed when full penetration was obtained.

ABSTRACT Key debates on improving vaccination coverage tend to focus on factors that affect uptake in the public health system while ignoring the private sector that plays an important role in providing health services in any low or middle-income country setting. Using in-depth interviews, we explored factors that influenced the decision of parents as well as pediatricians working in the private sector across 8 Indian cities on whether their children should be vaccinated with a particular vaccine Pediatricians and their relationship with parents was an important factor that influenced the decision on whether parents vaccinated their children with a particular vaccine or not. The decision to recommend a vaccine is taken on the principle that it is better to be safe than sorry than on any objective assessment of whether a child requires a particular vaccine or not. Family members and social factors also played a major role in the decision-making. According to some parents, vaccinating their child added an aspirational value to their growth. This is especially true of the newer vaccines that are considered optional in India. The cost of a vaccine did not come up as an inhibiting factor in the decision to vaccinate a child. Access to appropriate evidence was limited for both pediatricians and parents and evidence per se played a minimal role in the final decision to vaccinate a child or not. Far more important were the influences of factors such as relationship with the pediatrician, the role of decisions related to vaccination taken by people in the immediate social network.

This paper introduces an integrated approach based on data envelopment analysis (DEA), principal component analysis (PCA) and numerical taxonomy (NT) for total energy efficiency assessment and optimization in energy intensive manufacturing sectors. Total energy efficiency assessment and optimization of the proposed approach considers structural indicators in addition conventional consumption and manufacturing sector output indicators. The validity of the DEA model is verified and validated by PCA and NT through Spearman correlation experiment. Moreover, the proposed approach uses the measure-specific super-efficiency DEA model for sensitivity analysis to determine the critical energy carriers. Four energy intensive manufacturing sectors are discussed in this paper: iron and steel, pulp and paper, petroleum refining and cement manufacturing sectors. To show superiority and applicability, the proposed approach has been applied to refinery sub-sectors of some OECD (Organization for Economic Cooperation and Development) countries. This study has several unique features which are: (1) a total approach which considers structural indicators in addition to conventional energy efficiency indicators; (2) a verification and validation mechanism for DEA by PCA and NT and (3) utilization of DEA for total energy efficiency assessment and consumption optimization of energy intensive manufacturing sectors

The diagnosis and treatment of tuberculosis (TB) in India are characterized by heavy private-sector involvement. Delays in treatment remain poorly characterized among patients seeking care in the Indian private sector. To assess delays in TB diagnosis and treatment initiation among patients diagnosed in the private sector, and pathways to care in an urban setting. Cross-sectional survey of 289 consecutive patients diagnosed with TB in the private sector and referred for anti-tuberculosis treatment through a public-private mix program in Chennai from January 2014 to February 2015. Among 212 patients with pulmonary TB, 90% first contacted a formal private provider, and 78% were diagnosed by the first or second provider seen after a median of three visits per provider. Median total delay was 51 days (mean 68). Consulting an informal (rather than formally trained) provider first was associated with significant increases in total delay (absolute increase 22.8 days, 95%CI 6.2-39.5) and in the risk of prolonged delay >90 days (aRR 2.4, 95%CI 1.3-4.4). Even among patients seeking care in the formal (vs. informal) private sector in Chennai, diagnostic delays are substantial. Novel strategies are required to engage private providers, who often serve as the first point of contact.

A 448-year teak chronology from northwestern Thailand is used to assess past changes in the strength of the summer monsoon. The chronology is based on 30 living trees that extend from 1604 to 2005, and a 47-stump chronology that spans from 1558 to 1903. We used methods of cross dating and chronology building that address problems specifically found in teak. The result is a robust chronology with strong signal strength back to 1600 ad, and with variability retained at the multi-decadal scale. Variability in annual growth in teak from this area is dependent on rainfall and soil moisture availability at both the beginning and end of the monsoon season as confirmed by comparisons with temperature, rainfall and PDSI data. These correlation analyses confirm that our record is a proxy for summer monsoon strength and/or duration, and highlight the importance of soil moisture availability in the seasons of transition. The chronology reveals two prominent periods of decadal-scale drought in the early and mid 1700s that correspond to persistently warm sea surface temperature anomalies in the tropical Pacific as derived from Galapagos Island coral records. Speleothem data from central India also indicate protracted periods of drought for the 1700s. While these broad-scale eighteenth-century persistent droughts may be related to protracted El Nino-like conditions in the tropical Pacific, regional climate forcing over the Indian Ocean and western Pacific sectors appears to be a strong contributor as well. Spectral analyses reveal power in the ENSO range of variability from 2.2 to 4 years, and at the multi-decadal scale at 48.5 years. (orig.)

Full Text Available In Spain, the steel manufacture produces important quantities of by-products, representing between 15 and 20 % of total steel production. Most by-products are deposited on open air spaces causing serious economical and environmental problems, internationally, different recycling wais are studied, being the main alternative for these by-products as recycled aggregate. The possibility of recycling these by-products in construction sector depends on its possible volume instability because of the presence of some undesirable compounds. In current paper, two different black slags from electric arc furnace steel industry were chemically characterized, paying attention to some well-known compounds by theirs expansion effects, such as: free CaO, free MgO, chlorides and sulphates.
The analytical results carried out in the current research detected the presence of insignificant or null amounts of harmful compounds. Therefore, they should not have any negative incidence on phenomena of volume instability.

Connections: Superplasticity, Damascus Steels, Laminated Steels, and Carbon Dating
Wadsworth, Jeffrey
2016-12-01
In this paper, a description is given of the connections that evolved from the initial development of a family of superplastic plain carbon steels that came to be known as Ultra-High Carbon Steels (UHCS). It was observed that their very high carbon contents were similar, if not identical, to those of Damascus steels. There followed a series of attempts to rediscover how the famous patterns found on Damascus steels blades were formed. At the same time, in order to improve the toughness at room temperature of the newly-developed UHCS, laminated composites were made of alternating layers of UHCS and mild steel (and subsequently other steels and other metals). This led to a study of ancient laminated composites, the motives for their manufacture, and the plausibility of some of the claims relating to the number of layers in the final blades. One apparently ancient laminated composite, recovered in 1837 from the great pyramid of Giza which was constructed in about 2750 B.C., stimulated a carbon dating study of ancient steels. The modern interest in "Bladesmithing" has connections back to many of these ancient weapons.

Stainless steel is not only clean and smooth in its surface, but also it is superior in quality in terms of corrosion resistance and strength. So that, it is widely in use in the field of construction, chemical installations, and other industries. Growth of stainless steel industry started since the steel technology was developed for mass production in 1960s. Since then stainless steel industry grew rapidly on account of diversified development in this field and growth rate went up to 5.8% per year comparable to 2.3% of steel growth. The rapid growth is attributed to significant industry developments in Europe and Japan in the years of 1970s and 1980s. In addition to these the expansion of stainless steel industry in Korea and Taiwan. Presently Korea produces about 120,000 tons of stainless steel and occupies about 8% of international market. This means Korea become the second largest single country in world in stainless steel production. Moreover Korea is to reinforce its domestic production line by affiliating production companies, increasing of production capability, and specializing in types of stainless steel. This paper is to describe activity of material development, and types of stainless steel for industry use. (Hong, J. S.)

Full Text Available The contribution of Indian construction sector to the GDP is approximately 10%. Under new government policy, it is anticipated that $1000 Billion share for exclusively infrastructure segment would be completed within the next few years. Construction sector in developing country like India still depends on labor and the practice of mechanization, adopting to use of versatile construction equipment is not in force. The need for implementing new technologies and automation is essential to improve the quality, safety and efficiency. To meet the challenges ahead the construction, organizations should focus on utilization of machinery/equipment to achieve desirable results. Modern construction is characterized by the increase in utilization of equipment to accomplish numerous construction activities. The selection of construction equipment often affects the required amount of time and effort. It is therefore important for managements of construction organizations and planners to be familiar with the features of various types of equipment commonly used in construction activities. The selection of appropriate equipment is a crucial decision making process as it involves huge capital investment. The purpose of the present study is to develop a model pertaining to the factors influencing the selection of construction equipment by using interpretive structural modelling and the results indicate that productivity and safety are the important factors in selection of equipment in Indian construction organizations.

Multi-decadal modulation of the El Nino-Indian monsoon relationship by Indian Ocean variability
International Nuclear Information System (INIS)
Ummenhofer, Caroline C; Sen Gupta, Alexander; Li Yue; Taschetto, Andrea S; England, Matthew H
2011-01-01
The role of leading modes of Indo-Pacific climate variability is investigated for modulation of the strength of the Indian summer monsoon during the period 1877-2006. In particular, the effect of Indian Ocean conditions on the relationship between the El Nino-Southern Oscillation (ENSO) and the Indian monsoon is explored. Using an extended classification for ENSO and Indian Ocean dipole (IOD) events for the past 130 years and reanalyses, we have expanded previous interannual work to show that variations in Indian Ocean conditions modulate the ENSO-Indian monsoon relationship also on decadal timescales. El Nino events are frequently accompanied by a significantly reduced Indian monsoon and widespread drought conditions due to anomalous subsidence associated with a shift in the descending branch of the zonal Walker circulation. However, for El Nino events that co-occur with positive IOD (pIOD) events, Indian Ocean conditions act to counter El Nino's drought-inducing subsidence by enhancing moisture convergence over the Indian subcontinent, with an average monsoon season resulting. Decadal modulations of the frequency of independent and combined El Nino and pIOD events are consistent with a strengthened El Nino-Indian monsoon relationship observed at the start of the 20th century and the apparent recent weakening of the El Nino-Indian monsoon relationship.

Banerjee, S.P.
2005-06-01
The article, by the former director of the Indian school of Mines, Dhanbad, covers the major environmental management issues common to the majority of India's mining projects and gives recommendations for further improving practices, such as mine planning, fly ash utilization and conversion of mined lands to agriculture. India is likely to expand activities in mining of coal, iron ores, limestone and bauxite, mostly through opencast mining. The article mentions the regulations controlling environmental impacts of mining, the 1986 Environmental Protection Act and other measures. The 1994 Environmental Impact Assessment process was modified in 1997 to include the concept of public hearing. In 2003 the requirement of public hearing was limited to mines with lease area above 25 ha. In 2003 the Mineral Conservation and Development rules were amended to improve protection of the environment, reclamation and rehabilitation measures. Further deforestation cannot be avoided but the industry record for creating new forests on mined areas is improving. Issues of waste water treatment and dust abatement are outlined. 8 refs.

Full Text Available The steel industry is amongst the most energy-intensive industries also consuming large amounts of coal and emitting significant volumes of carbon dioxide (CO2. Studies indicate that steelmaking accounts for 6 - 7 % of world anthropogenic CO2 emissions, and 27 % of the total emissions of the world’s manufacturing sector. Steel manufacturers have responded to sustainable resource use and development adopting several measures attaining a reduction in energy consumption of 60 % in the last 50 years. The paper discusses Carbon Capture and Storage (CCS as a CO2 mitigation option, after the 2015 Paris Climate Conference (COP 21 and in relation to the European Regulation for CO2 measurement, reporting and verification.

To investigate the factors influencing the electrocardiogram results in the workers exposed to noise in steel-making and steel rolling workshops of an iron and steel plant. From September to December, 2013, cluster sampling was used to select 3 150 workers exposed to noise in the steel-making and steel-rolling workshops of an iron and steel plant, and a questionnaire survey and physical examinations were performed. The number of valid workers was 2 915, consisting of 1 606 workers in the steel-rolling workshop and 1 309 in the steel-making workshop. The electrocardiogram results of the workers in steel-making and steel-rolling workshops were analyzed. The overall abnormal rate of electrocardiogram was 26.35%, and the workers in the steel-making workshop had a significantly higher abnormal rate of electrocardiogram than those in the steel-rolling workshop(32.24% vs 21.54%, Pelectrocardiogram than female workers(27.59% vs 18.61%, Pelectrocardiogram than those who did not drink(28.17% vs 23.75%, Pelectrocardiogram than those who were not exposed to high temperature(29.43% vs 20.14%, Pelectrocardiogram in the workers with cumulative noise exposure levels of electrocardiogram results. High cumulative noise exposure, alcohol consumption, and high temperature may affect the abnormal rate of electrocardiogram in the workers exposed to noise in steel-making and steel-rolling workshops.

Steel fiber reinforced self-compacting concrete (SFRSCC) is a relatively new composite material which congregates the benefits of the self-compacting concrete (SCC) technology with the profits derived from the fiber addition to a brittle cementitious matrix. Steel fibers improve many of the properties of SCC elements including tensile strength, ductility, toughness, energy absorption capacity, fracture toughness and cracking. Although the available research regarding the influence of steel fibers on the properties of SFRSCC is limited, this paper investigates the bond characteristics between steel fiber and SCC firstly. Based on the available experimental results, the current analytical steel fiber pullout model (Dubey 1999) is modified by considering the different SCC properties and different fiber types (smooth, hooked) and inclination. In order to take into account the effect of fiber inclination in the pullout model, apparent shear strengths ( τ ( app)) and slip coefficient ( β) are incorporated to express the variation of pullout peak load and the augmentation of peak slip as the inclined angle increases. These variables are expressed as functions of the inclined angle ( ϕ). Furthurmore, steel-concrete composite floors, reinforced concrete floors supported by columns or walls and floors on an elastic foundations belong to the category of structural elements in which the conventional steel reinforcement can be partially replaced by the use of steel fibers. When discussing deformation capacity of structural elements or civil engineering structures manufactured using SFRSCC, one must be able to describe thoroughly both the behavior of the concrete matrix reinforced with steel fibers and the interaction between this composite matrix and discrete steel reinforcement of the conventional type. However, even though the knowledge on bond behavior is essential for evaluating the overall behavior of structural components containing reinforcement and steel fibers

Indian Economy is growing at 8% for the past few years and is expected to continue this momentum into the foreseeable future. To sustain this growth, power sector needs to build additional generation capacity at an unprecedented pace. However, continued dependence on fossil fuels (especially Coal and Oil) to power the growth of electricity generation capacity, is hardly sustainable in the long run. The reasons are well known - Environmental concerns, depleting fossil fuel resources, excessive dependency on Oil imports - that it hardly merits repetition. Renewable Energy source forms a miniscule portion (25 GW, {approx} 12%) of India's overall Energy consumption today (202 GW). The share of wind energy (17 GW) is 67% of the total renewable energy basket. But the contribution from offshore wind farms is non-existent, as all the wind energy generated in India is only through onshore Wind farms. India needs a policy framework to encourage the development of offshore wind farms. Several European countries, most notably the UK, Germany and Denmark, have effective offshore wind energy policies that have helped them to accelerate the growth of their offshore wind energy sector. This paper does an exhaustive study to identify the building blocks of a successful offshore wind energy policy initiative adopted by selected European countries, which can be leveraged by India to articulate its own offshore wind energy policy. This paper also suggests a model to predict the log-odds of growth of offshore wind energy sector in India. (Author)

Full Text Available Major noncommunicable diseases (NCDs share common behavioral risk factors and deep-rooted social determinants. India needs to address its growing NCD burden through health promoting partnerships, policies, and programs. High-level political commitment, inter-sectoral coordination, and community mobilization are important in developing a successful, national, multi-sectoral program for the prevention and control of NCDs. The World Health Organization′s "Action Plan for a Global Strategy for Prevention and Control of NCDs" calls for a comprehensive plan involving a whole-of-Government approach. Inter-sectoral coordination will need to start at the planning stage and continue to the implementation, evaluation of interventions, and enactment of public policies. An efficient multi-sectoral mechanism is also crucial at the stage of monitoring, evaluating enforcement of policies, and analyzing impact of multi-sectoral initiatives on reducing NCD burden in the country. This paper presents a critical appraisal of social determinants influencing NCDs, in the Indian context, and how multi-sectoral action can effectively address such challenges through mainstreaming health promotion into national health and development programs. India, with its wide socio-cultural, economic, and geographical diversities, poses several unique challenges in addressing NCDs. On the other hand, the jurisdiction States have over health, presents multiple opportunities to address health from the local perspective, while working on the national framework around multi-sectoral aspects of NCDs.
The Living Indian Critical Tradition

Full Text Available This paper attempts to establish the identity of something that is often considered to be missing – a living Indian critical tradition. I refer to the tradition that arises out of the work of those Indians who write in English. The chief architects of this tradition are Sri Aurobindo, C.D. Narasimhaiah, Gayatri Chakravorty Spivak and Homi K. Bhabha. It is possible to believe that Indian literary theories derive almost solely from ancient Sanskrit poetics. Or, alternatively, one can be concerned about the sad state of affairs regarding Indian literary theories or criticism in English. There have been scholars who have raised the question of the pathetic state of Indian scholarship in English and have even come up with some positive suggestions. But these scholars are those who are ignorant about the living Indian critical tradition. The significance of the Indian critical tradition lies in the fact that it provides the real focus to the Indian critical scene. Without an awareness of this tradition Indian literary scholarship (which is quite a different thing from Indian literary criticism and theory as it does not have the same impact as the latter two do can easily fail to see who the real Indian literary critics and theorists are.

The exposure of metallic components at aggressive high temperature environments, usually limit their usage at similar application because they suffer from severe oxidation attack. Copper alloys are used in a wide range of high-quality indoor and outdoor applications, statue parts, art hardware, high strength and high thermal conductivity applications. On the other hand, steel is commonly used as mechanical part of industrial set outs or in the construction sector due to its high mechanical properties. The aim of the present work is the examination of the oxidation resistance of pack cementation zinc coatings deposited on copper, leaded brass and steel substrates at elevated temperature conditions. Furthermore, an effort made to make a long-term evaluation of the coated samples durability. The oxidation results showed that bare substrates appear to have undergone severe damage comparing with the coated ones. Furthermore, the mass gain of the uncoated samples was higher than this of the zinc covered ones. Particularly zinc coated brass was found to be more resistant to oxidation conditions in which it was exposed as it has the lower mass gain as compared to the bare substrates and zinc coated copper. Zinc coated steel was also proved to be more resistive than the uncoated steel.

Hereditary polymorphic light eruption (HPLE) occurs unique ly in the American Indian and Inuit and exhibits autosomal dominant transmission. Because the cutaneous expression of HPLE resembles that of polymorphic light eruption (PLE) and because many non-Indians in the United States have American Indian heritage, some instances of PLE may actually be HPLE. Our purpose was to determine whether non-Indian patients with PLE have characteristics suggestive of HPLE. We surveyed in Nebraska 25 European-Caucasian and 36 African-American patients with PLE for American Indian heritage and photosensitive relatives. Nonphotosensitive subjects (52 Caucasians and 40 African Americans) were surveyed for American Indian heritage. American Indian heritage occurred in 11 Caucasian patients (44%); of those, seven (64%) had photosensitive relatives. Likewise, 29 African Americans (81%) had American Indian heritage; 19 (66%) of those had photosensitive relatives. American Indian heritage occurred in 10 Caucasian control subjects (19%) and in 34 African-American control subjects (85%). If American Indian heritage and a family history of photosensitivity are definitive for HPLE, seven (28%) of our Caucasian patients and 19 (53%) of our African-American patients have HPLE rather than PLE. We urge physicians who suspect PLE in non-Indians to ask about American Indian heritage and photosensitive relatives and to screen their present patients with PLE for such characteristics.
Indian Handicrafts in Globalization Times: An analysis of Global-Local Dynamics

2010-12-01
Full Text Available Globalization – which refers to the growing integration of societies, economies and cultures around the world, has become one of the most hotly-debated topics and key area of research among the policy makers, statesmen, corporate, politicians and academia respectively over the past few years. As India opens up her doors to the multinationals during the era of economic reform and liberalized market, putting an end to the ‘license raj’, it is not only the economies that often meet in the global market sphere, but also the people and cultures, which bring a new dimension to the multi-cultural setting. What we can see in present day modern world is that there is always a cross-cultural interaction between the ‘local’ and ‘global’ and the much discussed ‘global village’, is now not just a possibility but a reality despite many contradictions. Talking about Indian Handicrafts, which constitutes a significant segment of the decentralized sector of the economy, its export has reached at a commendable height. Indian folk art and crafts which are the integral parts of the Indian culture and tradition, are in high demand among the western consumers. Again, foreign fashion industry borrows a great deal from Indian appliquéd motifs Saree designs, an ethnic Indian wear. Needless to say, the borders between the world cultures are now eroding out and becoming irrelevant, therefore prompting to call it as a deterritorialized world.But notwithstanding, the real concern for many of us is that, can the ‘local’ really meet with the ‘global’ by truly sustaining its localness? The biggest problem in the Indian Handicraft industry is that the village craftsmen remain concerned that with free trade and mass production, hand-made products from other parts of the world will out price the products of their hard labour. So the basic question arises, is globalization a panacea for every human problems that the mother earth is facing now? With a

How to sustain rapid economic and urban growth with minimised detriment to environment is a key challenge for sustainable development and climate change mitigation in developing countries, which face constraints of technical and financial resources scarcity as well as dearth of infrastructure governance capacity. This paper attempts to address this question by investigating the driving forces of transport demand and relevant policy measures that facilitate mitigating GHG emissions in the urban transport sector in Indian cities based on a critical review of the literature. Our overview of existing literature and international experiences suggests that it is critical to improve urban governance in transport infrastructure quality and develop efficient public transport, coupled with integrated land use/transport planning as well as economic instruments. This will allow Indian cities to embark on a sustainable growth pathway by decoupling transport services demand of GHG emissions in the longer term. Appropriate policy instruments need to be selected to reconcile the imperatives of economic and urban growth, aspiration to higher quality of life, improvements in social welfare, urban transport-related energy consumption and GHG emissions mitigation target in Indian cities. - Highlights: → Investigating the relevant policies that facilitate mitigating GHG emissions in urban transport in Indian cities. → Determining the factors of increase in energy demand and carbon emissions in transport. → Improving urban governance in transport infrastructure with integrated transport planning. → Designing and implementing the policy and economic instruments for low-carbon urban transport in India.

There are limited primary data on the number of urban health care providers in private practice in developing countries like India. These data are needed to construct and test models that measure the efficacy of public stewardship of private sector health services. This study reports the number and characteristics of health resources in a 200 000 urban population in Pune. Data on health providers were collected by walking through the 15.46 sq km study area. Enumerated data were compared with existing data sources. Mapping was carried out using a Global Positioning System device. Metrics and characteristics of health resources were analyzed using ArcGIS 10.0 and Statistical Package for the Social Sciences, Version 16.0 software. Private sector health facilities constituted the majority (424/426, 99.5%) of health care services. Official data sources were only 39% complete. Doctor to population ratios were 2.8 and 0.03 per 1000 persons respectively in the private and public sector, and the nurse to doctor ratio was 0.24 and 0.71, respectively. There was an uneven distribution of private sector health services across the area (2-118 clinics per square kilometre). Bed strength was forty-fold higher in the private sector. Mandatory registration of private sector health services needs to be implemented which will provide an opportunity for public health planners to utilize these health resources to achieve urban health goals.

Steel production accounts for 25% of industrial carbon emissions. Long-term forecasts of steel demand and scrap supply are needed to develop strategies for how the steel industry could respond to industrialization and urbanization in the developing world while simultaneously reducing its environmental impact, and in particular, its carbon footprint. We developed a dynamic stock model to estimate future final demand for steel and the available scrap for 10 world regions. Based on evidence from developed countries, we assumed that per capita in-use stocks will saturate eventually. We determined the response of the entire steel cycle to stock saturation, in particular the future split between primary and secondary steel production. During the 21st century, steel demand may peak in the developed world, China, the Middle East, Latin America, and India. As China completes its industrialization, global primary steel production may peak between 2020 and 2030 and decline thereafter. We developed a capacity model to show how extensive trade of finished steel could prolong the lifetime of the Chinese steelmaking assets. Secondary steel production will more than double by 2050, and it may surpass primary production between 2050 and 2060: the late 21st century can become the steel scrap age.

Wenning Shen
Full Text Available The composite material of 304 stainless steel reinforced Q235 carbon steel has been prepared by modified hot-rolling process. The resulted material was characterized by scanning electron microscope, three-electrode method, fault current impact method, electrochemical potentiodynamic polarization curve measurement and electrochemical impedance spectroscopy. The results showed that metallurgical bond between the stainless steel layer and carbon steel substrate has been formed. The composite material exhibited good electrical conductivity and thermal stability. The average grounding resistance of the composite material was about 13/20 of dip galvanized steel. There has no surface crack and bubbling formed after fault current impact. The composite material led to a significant decrease in the corrosion current density in soil solution, compared with that of hot dip galvanized steel and bare carbon steel. On the basis polarization curve and EIS analyses, it can be concluded that the composite material showed improved anti-corrosion property than hot-dip galvanized steel.

Access to free essential medicines is a critical component of universal health coverage. However availability of essential medicines is poor in India with more than two-third of the people having limited or no access. This has pushed up private out-of-pocket expenditure due to medicines. The states of Punjab and Haryana are in the process of institutionalizing drug procurement models to provide uninterrupted access to essential medicines free of cost in all public hospitals and health centres. We undertook this study to assess the availability of medicines in public sector health facilities in the 2 states. Secondly, we also ascertained the quality of storage and inventory management systems in health facilities. The present study was carried out in 80 public health facilities across 12 districts in Haryana and Punjab states. Overall, within each state 1 MC, 6 DHs, 11 CHCs and 22 PHCs were selected for the study. Drug procurement mechanisms in both the states were studied through document reviews and in-depth interviews with key stakeholders. Stock registers were reviewed to collect data on availability of a basket of essential medicines -92 at Primary Health Centre (PHC) level, 132 at Community Health Centre (CHC) level and 160 at tertiary care (District Hospital/Medical College) level. These essential medicines were selected based on the Essential Medicine List (EML) of the Department of Health (DOH). Overall availability of medicines was 45.2% and 51.1% in Punjab and Haryana respectively. Availability of anti-hypertensives was around 60% in both the states whereas for anti-diabetics it was 44% and 47% in Punjab and Haryana respectively. Atleast one drug in each of the categories including analgesic/antipyretic, anti-helminthic, anti-spasmodic, anti-emetic, anti-hypertensive and uterotonics were nearly universally available in public sector facilities. On the contrary, medicines such as thrombolytics, anti-cancer and endocrine medicines were available in less

Screening, especially screening mammography, is vital for decreasing breast cancer incidence and mortality. Screening rates in American Indian women are low compared to other racial/ethnic groups. In addition, American Indian women are diagnosed at more advanced stages and have lower 5-year survival rate than others. To better address the screening rates of American Indian women, focus groups (N=8) were conducted with American Indian men (N=42) to explore their perceptions of breast cancer screening for American Indian women. Our intent was to understand men's support level toward screening. Using a community-based participatory approach, focus groups were audio-taped, transcribed verbatim, and analyzed using a text analysis approach developed by our team. Topics discussed included breast cancer and screening knowledge, barriers to screening, and suggestions to improve screening rates. These findings can guide strategies to improve knowledge and awareness, communication among families and health care providers, and screening rates in American Indian communities.
Behavior of Low Grade Steel Fiber Reinforced Concrete Made with Fresh and Recycled Brick Aggregates

Full Text Available In recent years, recycled aggregates from construction and demolition waste (CDW have been widely accepted in construction sectors as the replacement of coarse aggregate in order to minimize the excessive use of natural resources. In this paper, an experimental investigation is carried out to observe the influence of low grade steel fiber reinforcements on the stress-strain behavior of concrete made with recycled and fresh brick aggregates. In addition, compressive strength by destructive and nondestructive tests, splitting tensile strength, and Young’s modulus are determined. Hooked end steel wires with 50 mm of length and an aspect ratio of 55.6 are used as fiber reinforcements in a volume fraction of 0% (control case, 0.50%, and 1.00% in concrete mixes. The same gradation of aggregates and water-cement ratio (w/c=0.44 were used to assess the effect of steel fiber in all these concrete mixes. All tests were conducted at 7, 14, and 28 days to perceive the effect of age on different mechanical properties. The experimental results show that around 10%~15% and 40%~60% increase in 28 days compressive strength and tensile strength of steel fiber reinforced concrete, respectively, compared to those of the control case. It is observed that the effect of addition of 1% fiber on the concrete compressive strength is little compared to that of 0.5% steel fiber addition. On the other hand, strain of concrete at failure of steel fiber reinforced concrete has increased almost twice compared to the control case. A simple analytical model is also proposed to generate the ascending portions of the stress-strain curve of concrete. There exists a good correlation between the experimental results and the analytical model. A relatively ductile failure is observed for the concrete made with low grade steel fibers.

Despite several remaining questions, India's government is paving the way for foreign investments to help meet the country's capacity shortfall. A high-level delegation from India recently conducted meetings in the United Kingdom and the United States to promote foreign investment in the Indian power generation market. The delegation, led by Cabinet Secretary Naresh Chandra, met in late May and early June in London, Washington, Houston, New York and San Francisco to discuss October 1991 amendments to India's electricity law and policy changes designed to remove obstacles to foreign investment. The delegation said foreign investments are needed to meet additional capital requirements and to supply advanced technology. The move to the private sector was precipitated by projections of substantial shortfalls in generating capacity during the next five years. The government can supply only 28,000 MW of the estimated 39,369 MW required, and officials hope foreign investors will supply a significant portion of the shortfall. India's existing capacity totals 69,000 MW. This article discusses the opening market for independent power generation in India

Diffusion dialysis, acid retardation and nanofiltration plants were acquired from Europe and demonstrated in several Indian metal finishing companies over a three year period. These companies are primarily small and medium enterprises (SMEs). Free acid recovery rate from spent pickling baths using diffusion dialysis and retardation was in the range of 78-86% and 30-70% respectively. With nanofiltration, 80% recovery rate of rinse water was obtained. The demonstrations created awareness among the metal finishing companies to reuse resources (acid/water) from the effluent streams. However, lack of efficient oil separators, reliable chemical analysis and trained personnel as well as high investment cost limit the application of these technologies. Local manufacturing, plant customization and centralized treatment are likely to encourage the uptake of such technologies in the Indian metal finishing sector. Copyright © 2018 Elsevier Ltd.

D9 steels and their modified versions are envisaged for use as fuel cladding and wrapper materials in the Indian fast breeder reactor (FBR) programme. The role played by interstitially dissolved nitrogen in steel matrices for the stabilization of austenitic phase, increase of strength and corrosion resistance is well known. Various factors: the role of grain boundaries and the their orientation, stress mediation, grain fragmentation and production of short circuit paths as a result of compressive stress are known to affect the diffusion of nitrogen. Basically, cold working produces plethora of defects throughout the sample as compared to its solution annealed state. Our earlier studies on 1 x10"1"5 and 5x10"1"5 N"1"5 implanted Solution Annealed D9 (SAD9) showed significant vacancy-nitrogen complexes for higher fluence. Hence, thermal diffusion behaviour of nitrogen was studied in 5 x10"1"5 -N"1"5 implanted samples in solution annealed state. In the present study, to understand the influence of cold work, similar thermal diffusion behaviour of nitrogen has been studied in Cold Worked D9 steel (CWD9) using nuclear reaction analysis

Toumpis, Athanasios; Galloway, Alexander; Cater, Stephen; McPherson, Norman
2014-01-01
Highlights: • The friction stir welding speed on DH36 steel has been substantially increased. • Excellent quality welds offering potential economic advantages are obtained. • Friction stir welding of steel generates a very complex metallurgical system. • Slow and intermediate welding speed tensile samples fractured in the parent material. • Increasing traverse speed is seen to improve the impact toughness of the weld. - Abstract: Friction stir welding of steel presents an array of advantages across many industrial sectors compared to conventional fusion welding techniques. However, the fundamental knowledge of the friction stir welding process in relation to steel remains relatively limited. A microstructure and property evaluation of friction stir welded low alloy steel grade DH36 plate, commonly used in ship and marine applications has been undertaken. In this comprehensive study, plates of 2000 × 200 × 6 mm were butt welded together at varying rotational and traverse speeds. Samples were examined microscopically and by transverse tensile tests. In addition, the work was complemented by Charpy impact testing and micro-hardness testing in various regions of the weld. The study examined a wide range of process parameters; from this, a preliminary process parameter envelope has been developed and initial process parameter sets established that produce commercially attractive excellent quality welds through a substantial increase in the conventionally recognised weld traverse speed

Impacts of Energy Sector Emissions on PM2.5 Air Quality in Northern India
Karambelas, A. N.; Kiesewetter, G.; Heyes, C.; Holloway, T.
2015-12-01
India experiences high concentrations of fine particulate matter (PM2.5), and several Indian cities currently rank among the world's most polluted cities. With ongoing urbanization and a growing economy, emissions from different energy sectors remain major contributors to air pollution in India. Emission sectors impact ambient air quality differently due to spatial distribution (typical urban vs. typical rural sources) as well as source height characteristics (low-level vs. high stack sources). This study aims to assess the impacts of emissions from three distinct energy sectors—transportation, domestic, and electricity—on ambient PM2.5 in northern India using an advanced air quality analysis framework based on the U.S. EPA Community Multi-Scale Air Quality (CMAQ) model. Present air quality conditions are simulated using 2010 emissions from the Greenhouse Gas-Air Pollution Interaction and Synergies (GAINS) model. Modeled PM2.5 concentrations are compared with satellite observations of aerosol optical depth (AOD) from the Moderate Imaging Spectroradiometer (MODIS) for 2010. Energy sector emissions impacts on future (2030) PM2.5 are evaluated with three sensitivity simulations, assuming maximum feasible reduction technologies for either transportation, domestic, or electricity sectors. These simulations are compared with a business as usual 2030 simulation to assess relative sectoral impacts spatially and temporally. CMAQ is modeled at 12km by 12km and include biogenic emissions from the Community Land Model coupled with the Model of Emissions of Gases and Aerosols in Nature (CLM-MEGAN), biomass burning emissions from the Global Fires Emissions Database (GFED), and ERA-Interim meteorology generated with the Weather Research and Forecasting (WRF) model for 2010 to quantify the impact of modified anthropogenic emissions on ambient PM2.5 concentrations. Energy sector emissions analysis supports decision-making to improve future air quality and public health in

Disposal of biomass in the agriculture and steel slags in the steel industry provides a significant solution toward sustainability in China. Herein these two sectors were creatively combined as a novel method, i.e., biomass/CO 2 gasification using waste heat from hot slags where the influence of chemical compositions of steel slags, characterized as iron oxide content and basicity, on gasification thermodynamics, was systemically reported for the first time. Both the target gases of CO, H 2 and CH 4 and the polluted gases of NH 3 , NO and NO 2 were considered. It was first found that an increasing iron content and slag basicity continuously improved the CO yield at 600-1000°C and 800-1000°C, respectively; while the effect on polluted gas releases was limited. Moreover, the solid wastes after gasification could be utilized to provide nutrients and improve the soil in the agriculture, starting from which an integrated modern system was proposed herein.

Within the frame of the Emission Trading Scheme (ETS), the authors study job evolutions considered globally, not only those concerning sectors which will provide 'green jobs', but also those where job destructions may occur because of the implementation of the Grenelle de l'Environnement. They propose a qualitative rather than quantitative analysis of consequences, and typological approaches of the vulnerability of some worker categories with respect to retraining possibilities. For each sector whether it is submitted to the ETS system (electricity production, gas transport, urban heating, steel metallurgy, refining, paper industry, cement industry, building materials, chemical industry) or not (automotive industry, motorization, phyto-sanitary products, renewable energies, electromechanical industry), they analyse actor strategies, propose a diagnostic and draw some perspectives

Preparation and characterization of 304 stainless steel/Q235 carbon steel composite material
Shen, Wenning; Feng, Lajun; Feng, Hui; Cao, Ying; Liu, Lei; Cao, Mo; Ge, Yanfeng
The composite material of 304 stainless steel reinforced Q235 carbon steel has been prepared by modified hot-rolling process. The resulted material was characterized by scanning electron microscope, three-electrode method, fault current impact method, electrochemical potentiodynamic polarization curve measurement and electrochemical impedance spectroscopy. The results showed that metallurgical bond between the stainless steel layer and carbon steel substrate has been formed. The composite material exhibited good electrical conductivity and thermal stability. The average grounding resistance of the composite material was about 13/20 of dip galvanized steel. There has no surface crack and bubbling formed after fault current impact. The composite material led to a significant decrease in the corrosion current density in soil solution, compared with that of hot dip galvanized steel and bare carbon steel. On the basis polarization curve and EIS analyses, it can be concluded that the composite material showed improved anti-corrosion property than hot-dip galvanized steel.

This paper focuses on preserving and strengthening two resources culturally and socially important to the Shoshone-Bannock Indian Tribe on the Fort Hall Reservation in Idaho; their young people and the Pacific-Northwest Salmon. After learning that salmon were not returning in significant numbers to ancestral fishing waters at headwater spawning sites, tribal youth wanted to know why. As a result, the Indian Summer project was conceived to give Shoshone-Bannock High School students the opportunity to develop hands-on, workable solutions to improve future Indian fishing and help make the river healthy again. The project goals were to increase the number of fry introduced into the streams, teach the Shoshone-Bannock students how to use scientific methodologies, and get students, parents, community members, and Indian and non-Indian mentors excited about learning. The students chose an egg incubation experiment to help increase self-sustaining, natural production of steelhead trout, and formulated and carried out a three step plan to increase the hatch-rate of steelhead trout in Idaho waters. With the help of local companies, governmental agencies, scientists, and mentors students have been able to meet their project goals, and at the same time, have learned how to use scientific methods to solve real life problems, how to return what they have used to the water and land, and how to have fun and enjoy life while learning.

2014-05-01
Full Text Available This paper aims at constructing a measure of service quality for Indian private sector banks. The SERVQUAL model was used. In total 28 variables were considered to find their relative importance from customers’ point of view. Factor analysis was used to reduce redundant variables and finally four dimensions were identified that are the dependability with facility, guarantee, security with value added services and compassion with cordialness. Then RIDIT test was done to identify the prioritization pattern that customers assign to different variables. The result shows that customers believe that bank’s effort in instill confidence in customers, the bank’s concern for customers’ best interest and safety standards in transactions are vital factors for improving customer satisfaction.
Compresibility and sinterability of HCx PM steel diluted with stainless steels
Directory of Open Access Journals (Sweden)
Elena Gordo
2003-12-01
Full Text Available HCx powder metallurgy steel contains in its composition high contents of Cr and C, and significant quantities of alloy elements typical of tool steels (Mo, V, W, to provide the corrosion resistance of stainless steel with wear resistance of tool steels. HCx appears to be a suitable material for applications in aggressive environments, as valve seat inserts in automotive engines. However, this steel presents a low compressibility leading to high production costs. In this work, some results carried out to improve the compressibility of HCx are presented. The way to attempt this improvement is the dilution of base material with two stainless steels, the ferritic 430LHC and the austenitic 316L. The powder mixes prepared were uniaxially pressed to study the compressibility. The sinterability was study by determining of density, hardness, transverse rupture strength (TRS and microstructural evolution after vacuum sintering at different temperatures. As a result, better compressibility is observed in the mixes although not all of them present the properties required.

In recent years, demand side management (DSM) has emerged as an efficient utility planning strategy for reducing capacity shortages and improving system load factors. The Indian government is adopting various policies to implement DSM programs. DSM implementation involves a variety of interests with conflicting objectives, and a range of possible implementation strategies with varying implications for effectiveness, cost, feasibility, efficiency and stakeholder acceptance. This necessitates a critical comparison of the strategies to determine a preferred strategy or combination of strategies from each specific stakeholder's point of view. The present study evaluates DSM implementation strategies from a multiobjective perspective using the Analytic Hierarchy Process (AHP). Eight strategies and six criteria were considered. Forty utility, regulator, and consumer stakeholders were surveyed. The most highly ranked strategies involved creating dedicated funds and providing technical support to end users for effective implementation of DSM. (author)

Poor quality care in public sector hospitals coupled with the costs of care in the private sector have trapped India's poor in a vicious cycle of poverty, ill health and debt for many decades. To address this, the governments of Andhra Pradesh (AP) and Maharashtra (MH), India, have attempted to improve people's access to hospital care by partnering with the private sector. A number of government-sponsored schemes with differing specifications have been launched to facilitate this strategy. This article aims to compare changes in access to, and affordability and efficiency of private and public hospital inpatient (IP) treatments between MH and AP from 2004 to 2012 and to assess whether the health financing innovations in one state resulted in larger or smaller benefits compared with the other. We used data from household surveys conducted in 2004 and 2012 in the two states and undertook a difference-in-difference (DID) analysis. The results focus on hospitalization, out-of-pocket expenditure and length of stay. The average IP expenditure for private hospital care has increased in both states, but more so in MH. There was also an observable increase in both utilization of and expenditure on nephrology treatment in private hospitals in AP. The duration of stay recorded in days for private hospitals has increased slightly in MH and declined in AP with a significant DID. The utilization of public hospitals has reduced in AP and increased in MH. The state of AP appears to have benefited more than MH in terms of improved access to care by involving the private sector. The Aarogyasri scheme is likely to have contributed to these impacts in AP at least in part. Our study needs to be followed up with repeated evaluations to ascertain the long-term impacts of involving the private sector in providing hospital care.

2010-06-01
Full Text Available Case Carburized (CC low carbon steels containing Ni, Cr and Mo alloying elements are widely used for transmission gears in automobile, as it possesses desired mechanical properties. In order to cut cost and save scarce materials like Ni and Mo for strategic applications, steel alloyed with Boron has been developed, which gives properties comparable to Ni-Cr-Mo alloyed steel. In the process of steel development, care was taken to ensure precipitation of boron which results in precipitation hardening. The characterization of the developed boron steel had exhibited properties comparable to Ni-Cr-Mo alloyed steel and superior to conventional boron steel.

We investigated shelled pteropod abundance and biomass with a 100-μm closing net, and their estimated downward fluxes using a sediment trap installed in a drifter buoy in the Indian sector of the Antarctic Ocean during the austral summer. Over 90% pteropod abundance was distributed in the upper 50 m; 70-100% were immature veligers. Limacina retroversa was dominant in the >0.2 mm individuals north of 60°S, L. helicina dominated south of 62°S, while populations around 60-62°S were mixed. Unidentifiable small Limacina spp. (ssL) were highly abundant in the upper 50 m at 60°S, 63°S, and 64°S on 110°E and 63°S on 115°E, although their estimated particulate organic carbon (POC) biomasses were less than that of Limacina adults. Adult females bearing egg clusters were found in the 0-50 m layer; the veligers likely grew within a short period. The mean downward flux of ssL and veligers at 70 m around 60°S, 110°E was 5.1 ± 1.6 × 103 ind. m-2 d-1 (0.6 ± 0.2 mg C m-2 d-1), which was 3.8% of the integrated ssL and veligers in the upper 70 m, suggesting that at least 4% of the veligers were produced daily in the surface layers. The mid-summer spawned ssL and veligers likely contributed to the subsequent increase in large pteropods in the area.

China faces a significant challenge in the years ahead to continue to provide essential materials and products for a rapidly-growing economy while addressing pressing environmental concerns. China's industrial sector is heavily dependent on the country's abundant, yet polluting, coal resources. While tremendous energy conservation and environmental protection achievements were realized in the industrial sector in the past, there remains a great gulf between the China's level of energy efficiency and that of the advanced countries of the world. Internationally, significant energy efficiency improvement in the industrial sector has been realized in a number of countries using an innovative policy mechanism called Voluntary Agreements. This paper describes international experience with Voluntary Agreements in the industrial sector as well as the development of a pilot program to test the use of such agreements with two steel mills in Shandong Province, China.

Full Text Available For further research on the precondition and interoperability model of interaction ladles among continuous caster, this article takes steel ladle of Y steel works as the object of research. On the basis of turnover number calculation model of single cast steel ladle, the relationship between cast number and the turnover number and turnover times and last turnover number are further analyzed. The simulation of steel ladle turnover rules was taken on the 2 continuous casters with Gantt chart. After that, the relationships between turnover number and last turnover number and non-turnover number are researched deeply. Combining with the Gantt chart, the expressions of start casting time and empty ladle ending time and heavy ladle starting time were put forward. The precondition of steel ladle interaction is obtained, which means the exchange ladle should not undertaking transport task in first stop continuous caster, and the empty ladle end time of exchange ladle of first stop continuous caster should early than the heavy ladle start time of last stop continuous caster. After applying the model to practice, 3 steel ladles of No.2 continuous caster can be reduced. This research results is supplying theoretical basis for steel ladle controlling and production organization optimization, and enriches the theory and method of metallurgical process integration.

Highlights: • The role of oxide particles in α/α′ phase decomposition behavior; microstructure of phase decomposition observed by TEM. • The characteristics of ductility loss caused by age-hardening. • Correlation of phase decomposition and age-hardening explained by dispersion strengthened models. • Age-hardening susceptibility of ODS steels and SUS430 steel. - Abstract: The effect of aging on high-Cr ferritic steels was investigated with focusing on the role of oxide particles in α/α′ phase decomposition behavior. 12Cr-oxide dispersion strengthened (ODS) steel, 15Cr-ODS steel and commercial SUS430 steel were isothermally aged at 475 °C for up to 10,000 h. Thermal aging caused a larger hardening in SUS430 than 15Cr-ODS, while 12Cr-ODS showed almost no hardening. A characteristic of the ODS steels is that the hardening was not accompanied by the significant loss of ductility that was observed in SUS430 steel. After aging for 2000 h, SUS430 steel shows a larger ductile–brittle transition temperature (DBTT) shift than 15Cr-ODS steel, which suggests that the age-hardening susceptibility is lower in 15Cr-ODS steel than in conventional SUS430 steel. Thermal aging leaded to a large number of Cr-rich α′ precipitates, which were confirmed by transmission electron microscopy (TEM). Correlation of age-hardening and phase decomposition was interpreted by Orowan type strengthening model. Results indicate that oxide particles cannot only suppress ductility loss, but also may influence α/α′ phase decomposition kinetics.

The relationship between the Indian Ocean and the Indian summer monsoon (ISM) and their respective influence over the Indo-Western North Pacific (WNP) region are examined in the absence of El Niño Southern Oscillation (ENSO) in two partially decoupled global experiments. ENSO is removed by nudging the tropical Pacific simulated sea surface temperature (SST) toward SST climatology from either observations or a fully coupled control run. The control reasonably captures the observed relationships between ENSO, ISM and the Indian Ocean Dipole (IOD). Despite weaker amplitude, IODs do exist in the absence of ENSO and are triggered by a boreal spring ocean-atmosphere coupled mode over the South-East Indian Ocean similar to that found in the presence of ENSO. These pure IODs significantly affect the tropical Indian Ocean throughout boreal summer, inducing a significant modulation of both the local Walker and Hadley cells. This meridional circulation is masked in the presence of ENSO. However, these pure IODs do not significantly influence the Indian subcontinent rainfall despite overestimated SST variability in the eastern equatorial Indian Ocean compared to observations. On the other hand, they promote a late summer cross-equatorial quadrupole rainfall pattern linking the tropical Indian Ocean with the WNP, inducing important zonal shifts of the Walker circulation despite the absence of ENSO. Surprisingly, the interannual ISM rainfall variability is barely modified and the Indian Ocean does not force the monsoon circulation when ENSO is removed. On the contrary, the monsoon circulation significantly forces the Arabian Sea and Bay of Bengal SSTs, while its connection with the western tropical Indian Ocean is clearly driven by ENSO in our numerical framework. Convection and diabatic heating associated with above-normal ISM induce a strong response over the WNP, even in the absence of ENSO, favoring moisture convergence over India.

Represented by approximately 85 species, Hemidactylus is one of the most diverse and widely distributed genera of reptiles in the world. In the Indian subcontinent, this genus is represented by 28 species out of which at least 13 are endemic to this region. Here, we report the phylogeny of the Indian Hemidactylus geckos based on mitochondrial and nuclear DNA markers sequenced from multiple individuals of widely distributed as well as endemic congeners of India. Results indicate that a majority of the species distributed in India form a distinct clade whose members are largely confined to the Indian subcontinent thus representing a unique Indian radiation. The remaining Hemidactylus geckos of India belong to two other geographical clades representing the Southeast Asian and West-Asian arid zone species. Additionally, the three widely distributed, commensal species (H. brookii, H. frenatus and H. flaviviridis) are nested within the Indian radiation suggesting their Indian origin. Dispersal-vicariance analysis also supports their Indian origin and subsequent dispersal out-of-India into West-Asian arid zone and Southeast Asia. Thus, Indian subcontinent has served as an important arena for diversification amongst the Hemidactylus geckos and in the evolution and spread of its commensal geckos. Copyright 2010 Elsevier Inc.

A market for renewable energy credits in the Indian power sector
International Nuclear Information System (INIS)
Singh, Anoop
2009-01-01
Electricity generation from renewable energy sources in India has been promoted through a host of fiscal policies and preferential tariff for electricity produced from the same. The fiscal policies include tax incentives and purchase of electricity generated through renewable energy sources. The enactment of the Electricity Act 2003 (the Act) has lent further support to renewable energy by stipulating purchase of a certain percentage of the power procurement by distribution utilities from renewable energy sources. The renewable portfolio obligation as well as the feed-in tariff for power procurement has been specified by a number of State Electricity Regulatory Commissions (SERCs) for the respective state under their jurisdiction. A feed-in tariff determined through a cost-plus approach under a rate of return framework lacks incentive for cost minimisation and does not encourage optimal utilisation of renewable energy resources in the country. Such regulatory provisions differ across states. The prevalent practice of fixing a renewable portfolio obligation along with cost-based feed-in tariffs disregards economic efficiency. The paper proposes nationally tradable renewable energy credits scheme for achieving the targets set by the respective SERCs as renewable portfolio obligation. This would reduce the cost of compliance to a renewable portfolio obligation, and would encourage efficient resource utilisation and investment in appropriate technologies. The paper highlights its advantages and implementation issues. This paper discusses regulatory developments for promotion of renewable energy in various Indian states. The paper also identifies a number of issues related to regulations concerning renewable portfolio obligation. (author)

Full Text Available The real sector is a strategic component of an economy because it produces and distributes tangible goods and services required to satisfy aggregate demand in the economy. For this reason, there is the need for adequate credit flow from the banking industry to the real sector, which in the Nigerian case, the credit flow has been grossly inadequate. This study is carried out to examine the impact of credit to private sector (CPS on the real sector of Nigeria with a view to assess the significant contribution of CPS to real sector growth in Nigeria. The study used aggregate time series data from 1986 to 2010, which was drawn from central bank of Nigeria (CBN statistical bulletin and CBN annual report and statement of accounts. The data was analysed using multiple regression and based on the coefficient of determination (R square, the study reveals a 96.1% variation between the CPS and real sector growth in Nigeria. The study cocludes that there is a statistically significant impact of credit to private sector on the real sector of Nigeria. This, suggest that the performance of the real sector is greatly influence by credit to private sector. The study recommends that the federal government of Nigeria through the central bank of Nigeria (CBN should enhance the financing of the real sector as well as improve credit flow to the sector because of its strategic importance in creating and generating growth of the economy.

The road transport sector is the largest consumer of commercial fuel energy within the transportation system in India and accounts for nearly 35% of the total liquid commercial fuel consumption by all sectors. Gasoline and diesel consumption for road transportation have quadrupled between 1980 and 2000 due to about nine times increase in the number of vehicles and four-fold increase in freight and passenger travel demands. The paper elaborates the trends of energy consumption and consequent emissions of greenhouse gases such as CO 2 , CH 4 and N 2 O and ozone precursor gases like CO, NO x and NMVOC in the road transport sector in India for the period from 1980 to 2000. For the first time, efforts have been made to apportion the fuels, both diesel and gasoline, across different categories of vehicles operating on the Indian roads. In order to generate more comprehensive and complete emission estimates, additionally, other minor fuel types like light diesel oil and fuel oil along with lubricants have also been taken into account. Emission estimates have revealed that nearly 27 Mt of CO 2 were emitted in 1980, increasing to about 105 Mt in 2000. Similar trends have also been observed for other gases. Further scope for improvements in emission estimation is possible by generating country specific emission factors for different vehicle categories and improvement in documentation of fuel consumption at segregated levels by fuel types and vehicle types

Nickel-base hardfacing alloys have been chosen to replace cobalt-base alloys as hardfacing material for components of the Indian Prototype Fast Breeder Reactor, for minimising the dose rate to personnel during maintenance and decommissioning, and to reduce the shielding thickness required for component handling. Induced activity, dose rate and shielding computations showed that replacing cobalt-base alloys with nickel-base alloys for hardfacing of components would result in a marked reduction in both the dose rate from the components and the thickness of lead handling flasks. Long-term ageing studies on the nickel-base hardface deposits on austenitic stainless steel showed that the hardface deposit would retain adequate hardness at the end of the components' design service-life of 40 years of exposure at 823 K

Antoci, Angelo; Galeotti, Marcello; Iannucci, Gianluca; Russu, Paolo
2015-01-01
This paper studies the dynamics of a two-sector economy (with a natural resource-dependent sector and an industrial sector) characterized by free inter-sectoral labor mobility and heterogeneity of agents (workers and entrepreneurs). In such a context, we analyze the effects of the deterioration of natural resources, caused by the production activity of both sectors, on inter-sectoral movements of the labor force (structural changes), on ecological dynamics and on the revenues of workers and entrepreneurs. As in the seminal work by Matsuyama (1992), we obtain that a low productivity of labor in the resource-dependent sector can fuel the industrialization process. However, differently from Matsuyama, in our model the industrialization process may give rise to a reduction in workers’ revenues if the contribution to environmental depletion of the industrial sector, per unit of product, is higher than that of the resource-dependent one.
MICROALLOYED STEELS FOR THE AUTOMOTIVE INDUSTRY
Directory of Open Access Journals (Sweden)
Debanshu Bhattacharya
2014-12-01
Full Text Available Two major drivers for the use of newer steels in the automotive industry are fuel efficiency and increased safety performance. Fuel efficiency is mainly a function of weight of steel parts, which in turn, is controlled by gauge and design. Safety is determined by the energy absorbing capacity of the steel used to make the part. All of these factors are incentives for the U.S. automakers to use both Highly Formable and Advanced High Strength Steels (AHSS to replace the conventional steels used to manufacture automotive parts in the past. AHSS is a general term used to describe various families of steels. The most common AHSS is the dual-phase steel that consists of a ferrite-martensite microstructure. These steels are characterized by high strength, good ductility, low tensile to yield strength ratio and high bake hardenability. Another class of AHSS is the complex-phase or multi-phase steel which has a complex microstructure consisting of various phase constituents and a high yield to tensile strength ratio. Transformation Induced Plasticity (TRIP steels is another class of AHSS steels finding interest among the U.S. automakers. These steels consist of a ferrite-bainite microstructure with significant amount of retained austenite phase and show the highest combination of strength and elongation, so far, among the AHSS in use. High level of energy absorbing capacity combined with a sustained level of high n value up to the limit of uniform elongation as well as high bake hardenability make these steels particularly attractive for safety critical parts and parts needing complex forming. A relatively new class of AHSS is the Quenching and Partitioning (Q&P steels. These steels seem to offer higher ductility than the dual-phase steels of similar strengths or similar ductility as the TRIP steels at higher strengths. Finally, martensitic steels with very high strengths are also in use for certain parts. The most recent initiative in the area of AHSS

Full Text Available For a rather long time, basic research projects have been focused on examinations of mechanical properties for Rapid Solidification Powder (RSP steels. These state-of-art steels are commonly known as “powdered steels“. In fact, they combine distinctive attributes of conventional steel alloys with unusual resistance of construction material manufactured by so called “pseudo-powdered” metallurgy.Choice of suitable materials for experimental verification was carried out based on characteristic application of so called “modern steel”. First, groups of stainless and tool steel types (steel grades ČSN 17 and 19 were selected. These provided representative specimens for the actual comparison experiment. For stainless steel type, two steel types were chosen: hardenable X47Cr14 (ČSN 17 029 stainless steel and non-hardenable X2CrNiMo18-14-3 (ČSN 17 350 steel. They are suitable e.g. for surgical tools and replacements (respectively. For tooling materials, C80U (ČSN 19 152 carbon steel and American D2 highly-alloyed steel (ČSN “equivalent” being 19 572 steel were chosen for the project. Finally, the M390 Böhler steel was chosen as representative of powdered (atomized steels. The goal of this paper is to discuss structural aspects of modern stainless and tool steel types and to compare them against the steel made by the RSP method. Based on the paper's results, impact of powdered steel structural characteristics on the resistance to crack initiation shall be evaluated.

The overall goal of this project is to establish a network of TCUs with essential advanced manufacturing (AM) facilities, associated training and education programs, and private sector and federal agency partnerships to both prepare an American Indian AM workforce and create economic and employment opportunities within Tribal communities through design, manufacturing, and marketing of high quality products. Some examples of high quality products involve next generation grid components such as mechanical energy storage, cabling for distribution of energy, and electrochemical energy storage enclosures. Sandia National Laboratories (Sandia) is tasked to provide technical advising, planning, and academic program development support for the TCU/American Indian Higher Education Consortium (AIHEC) Advanced Manufacturing Project. The TCUs include Bay Mills Community College (BMCC), Cankdeska Cikana Community College (CCCC), Navajo Technical University (NTU), Southwestern Indian Polytechnic Institute (SIPI), and Salish Kooteani College. AIHEC and Sandia, with collaboration from SIPI, will be establishing an 8-week summer institute on the SIPI campus during the summer of 2017. Up to 20 students from TCUs are anticipated to take part in the summer program. The goal of the program is to bring AM science, technology, engineering, and mathematics (STEM) awareness and opportunities for the American Indian students. Prior to the summer institute, Sandia will be providing reviews on curriculum plans at the each of the TCUs to ensure the content is consistent with current AM design and engineering practice. In addition, Sandia will provide technical assistance to each of the TCUs in regards to their current AM activities.
Steel-reinforced concrete-filled steel tubular columns under axial and lateral cyclic loading

2018-03-01
SRCFT columns are formed by inserting a steel section into a concrete-filled steel tube. These types of columns are named steel-reinforced concrete-filled steel tubular (SRCFT) columns. The current study aims at investigating the various types of reinforcing steel section to improve the strength and hysteresis behavior of SRCFT columns under axial and lateral cyclic loading. To attain this objective, a numerical study has been conducted on a series of composite columns. First, FEM procedure has been verified by the use of available experimental studies. Next, eight composite columns having different types of cross sections were analyzed. For comparison purpose, the base model was a CFT column used as a benchmark specimen. Nevertheless, the other specimens were SRCFT types. The results indicate that reinforcement of a CFT column through this method leads to enhancement in load-carrying capacity, enhancement in lateral drift ratio, ductility, preventing of local buckling in steel shell, and enhancement in energy absorption capacity. Under cyclic displacement history, it was observed that the use of cross-shaped reinforcing steel section causes a higher level of energy dissipation and the moment of inertia of the reinforcing steel sections was found to be the most significant parameter affecting the hysteresis behavior of SRCFT columns.

Recent advancement in bulk metallic glasses, whose properties are usually superior to their crystalline counterparts, has stimulated great interest in fabricating bulk amorphous steels. While a great deal of effort has been devoted to this field, the fabrication of structural amorphous steels with large cross sections has remained an alchemist's dream because of the limited glass-forming ability (GFA) of these materials. Here we report the discovery of structural amorphous steels that can be cast into glasses with large cross-section sizes using conventional drop-casting methods. These new steels showed interesting physical, magnetic, and mechanical properties, along with high thermal stability. The underlying mechanisms for the superior GFA of these materials are discussed

2011-12-01
This study aimed to delineate the anthropometric measurements of the noses of young women of an Indian population and to compare them with the published ideals and average measurements for white women. This anthropometric survey included a volunteer sample of 100 young Indian women ages 18 to 35 years with Indian parents and no history of previous surgery or trauma to the nose. Standardized frontal, lateral, oblique, and basal photographs of the subjects' noses were taken, and 12 standard anthropometric measurements of the nose were determined. The results were compared with published standards for North American white women. In addition, nine nasal indices were calculated and compared with the standards for North American white women. The nose of Indian women differs significantly from the white nose. All the nasal measurements for the Indian women were found to be significantly different from those for North American white women. Seven of the nine nasal indices also differed significantly. Anthropometric analysis suggests differences between the Indian female nose and the North American white nose. Thus, a single aesthetic ideal is inadequate. Noses of Indian women are smaller and wider, with a less projected and rounded tip than the noses of white women. This study established the nasal anthropometric norms for nasal parameters, which will serve as a guide for cosmetic and reconstructive surgery in Indian women.

The dissimilar materials welded joints of high manganese non-magnetic steel/carbon steel (hereafter referred to as DMW joints), in which weld defects such as hot crack or blowhole are not found, were the good quality. Tensile strength of DMW joints was 10% higher than that of the base metal of carbon steel. In the bend tests, the DMW joints showed the good ductility without crack. Charpy absorbed energy at 0(degC) of the DMW joints was over 120(J) in the bond where it seems to be the lowest. Large hardening or softening was not detected in the heat affected zone. Fatigue strength of the DMW joints is almost the same with that of the welded joints of carbon steel/carbon steel. As the fatigue strength of the DMW joints exceeds the fatigue design standard curve of JSSC for carbon steel welded joints, the DMW joints can be treated the same as the welded joints of carbon steel/carbon steel of which strength is lower than that of high manganese non-magnetic steel, from the viewpoint of the fatigue design.

This report describes the survey results of the scrap iron and steel recycling industries in Thailand and Indonesia. The purpose of this survey is to extract problems obstructing the scrap iron and steel recycling, to recognize the present situation and predict the future situation, and to examine the possibility of international cooperation. As a result of the survey, it was found that the quality of scrap collected in the domestic market is poor as it contains too many impurities for it to be utilized for the manufacture of many higher quality iron and steel products. The actual quantity of domestically collected scrap is too low to support the expected growth in demand in each nation. Current environmental management practices are largely concerned with the construction of wastewater treatment facilities and the extraction of furnace dust. However, the lack of enforcement of environmental regulations does not encourage companies to implement sound environmental practices. Neither government actively promotes and investigates iron and steel recycling in the domestic, commercial or industrial sectors. Collaboration with overseas nations having more advanced iron and steel industries could be helpful to the scrap recycling industry in both nations. 6 figs., 21 tabs.
Damascus steel ledeburite class
Sukhanov, D. A.; Arkhangelsky, L. B.; Plotnikova, N. V.
2017-02-01
Discovered that some of blades Damascus steel has an unusual nature of origin of the excess cementite, which different from the redundant phases of secondary cementite, cementite of ledeburite and primary cementite in iron-carbon alloys. It is revealed that the morphological features of separate particles of cementite in Damascus steels lies in the abnormal size of excess carbides having the shape of irregular prisms. Considered three hypotheses for the formation of excess cementite in the form of faceted prismatic of excess carbides. The first hypothesis is based on thermal fission of cementite of a few isolated grains. The second hypothesis is based on the process of fragmentation cementite during deformation to the separate the pieces. The third hypothesis is based on the transformation of metastable cementite in the stable of angular eutectic carbide. It is shown that the angular carbides are formed within the original metastable colony ledeburite, so they are called “eutectic carbide”. It is established that high-purity white cast iron is converted into of Damascus steel during isothermal soaking at the annealing. It was revealed that some of blades Damascus steel ledeburite class do not contain in its microstructure of crushed ledeburite. It is shown that the pattern of carbide heterogeneity of Damascus steel consists entirely of angular eutectic carbides. Believe that Damascus steel refers to non-heat-resistant steel of ledeburite class, which have similar structural characteristics with semi-heat-resistant die steel or heat-resistant high speed steel, differing from them only in the nature of excess carbide phase.

Washington Irving and the American Indian.
Littlefield, Daniel F., Jr.
1979-01-01
Some modern scholars feel that Washington Irving vacillated between romanticism and realism in his literary treatment of the American Indian. However, a study of all his works dealing with Indians, placed in context with his non-Indian works, reveals that his attitude towards Indians was intelligent and enlightened for his time. (CM)

In the present paper, a systematic corrosion study has been carried out on DMR-1700 steel to understand the protective nature of oxide scale that forms on its surface under marine environmental conditions. Further, the studies related to oxide scales as well as pitting and crevice corrosion resistance of both stainless steels and widely used low alloy steel EN24 in marine environment have been studied for comparison purpose. The surface morphologies of corroded steels have been observed under scanning electron microscope (SEM) in order to understand the nature of corrosion. A high performance protective coating that has been developed for protection of low alloy steels DMR-1700 and EN24 against corrosion is presented after stressing the importance of surface engineering in enhancing the life of steels. Based on the studies with different techniques, DMR-1700 steel has been recommended for manufacture of components used in aerospace systems in association with appropriate protective coating for improving their efficiency

Highlights: • Solid state coating by friction surfacing method. • D2 tool steel is coated over relatively softer low carbon steel. • Defect free interface between tool steel coating and low carbon steel substrate. • D2 coatings exhibited higher hardness and good wear resistance. • Highly refined martensitic microstructure in the coating. - Abstract: In this work D2 tool steel coating is produced over a low carbon steel substrate using friction surfacing process. The process parameters are optimized to get a defect free coating. Microstructural characterization is carried out using optical microscopy, scanning electron microscopy and X-ray diffraction. Infrared thermography is used to measure the thermal profile during friction surfacing of D2 steel. Wear performance of the coating is studied using Pin-on-Disk wear tests. A lower rotational speed of the consumable rod and higher translational speed of the substrate is found to result in thinner coatings. Friction surfaced D2 steel coating showed fine-grained martensitic microstructure compared to the as-received consumable rod which showed predominantly ferrite microstructure. Refinement of carbides in the coating is observed due to the stirring action of the process. The infrared thermography studies showed the peak temperature attained by the D2 coating to be about 1200 °C. The combined effect of martensitic microstructure and refined carbides resulted in higher hardness and wear resistance of the coating

Light-weighting of passenger cars using high-strength steel or aluminum is a common emissions mitigation strategy. We provide a first estimate of the global impact of light-weighting by material substitution on GHG emissions from passenger cars and the steel and aluminum industries until 2050. We develop a dynamic stock model of the global car fleet and combine it with a dynamic MFA of the associated steel, aluminum, and energy supply industries. We propose four scenarios for substitution of conventional steel with high-strength steel and aluminum at different rates over the period 2010-2050. We show that light-weighting of passenger cars can become a "gigaton solution": Between 2010 and 2050, persistent light-weighting of passenger cars can, under optimal conditions, lead to cumulative GHG emissions savings of 9-18 gigatons CO2-eq compared to development business-as-usual. Annual savings can be up to 1 gigaton per year. After 2030, enhanced material recycling can lead to further reductions: closed-loop metal recycling in the automotive sector may reduce cumulative emissions by another 4-6 gigatons CO2-eq. The effectiveness of emissions mitigation by material substitution significantly depends on how the recycling system evolves. At present, policies focusing on tailpipe emissions and life cycle assessments of individual cars do not consider this important effect.

Methods of making bainitic steel materials
Bakas, Michael Paul; Chu, Henry Shiu-Hung; Zagula, Thomas Andrew; Langhorst, Benjamin Robert
2018-01-16
Methods of making bainitic steels may involve austenitizing a quantity of steel by exposing the quantity of steel to a first temperature. A composition of the quantity of steel may be configured to impede formation of non-bainite ferrite, pearlite, and Widmanstatten ferrite. The quantity of steel may be heat-treated to form bainite by exposing the quantity of steel to a second, lower temperature. The second, lower temperature may be stabilized by exposing the quantity of steel to the second, lower temperature in the presence of a thermal ballast.

Highlights: • Microstructure and corrosion performance are compared for two structural steels. • Microstructure evolution shows primarily ferrite-pearlite in both the steels. • Steels show higher corrosion rate in 1% HCl solution than in 3.5% NaCl solution. • The corrosion products show the presence of oxide, hydroxide and oxy-hydroxides. • The corroded surface reveals morphologies like flowery, cotton balls and rosette. - Abstract: A comparison on microstructure and corrosion performance has been made between the two structural steels used in old railway girder bridge (Sample A) and modern grades of weathering structural steel (Sample B). The microstructures, viewed under optical microscope and scanning electron microscope (SEM), show mainly ferrite-pearlite phase constituents in both the steels, A and B. The phase fraction analysis shows higher amount of pearlite in steel A compared to that of steel B. The grain size of steel A is larger than that of steel B under identical processing condition. The immersion corrosion test in 3.5% NaCl shows that the corrosion rate of steel A increases with time, while the same for steel B decreases with time. On the other hand, corrosion test in 1% HCl shows that the corrosion rate of both steel A and B is higher as compared to that of NaCl which always decreases with time. The XRD analysis of corrosion products show the presence of many oxides, hydroxide and oxy-hydroxide like Lepidocrocite (γ-FeOOH), Goethite (α-FeOOH), Akaganeite (β-FeOOH), Magnetite (Fe_3O_4) and Maghemite (γ-Fe_2O_3) in both the steels. The SEM images of corroded surfaces reveal different morphologies like flowery, cotton balls and rosette etc. which indicate that the corrosion products primarily contain Lepidocrocite (γ-FeOOH), Goethite (α-FeOOH) and Akaganeite (β-FeOOH).

In the present study, 3 mm-thick plates of 304 stainless steel and st37 steel were welded together by friction stir welding at a welding speed of 50 mm/min and tool rotational speed of 400 and 800 rpm. X-ray diffraction test was carried out to study the phases which might be formed in the welds. Metallographic examinations, and tensile and microhardness tests were used to analyze the microstructure and mechanical properties of the joint. Four different zones were found in the weld area except the base metals. In the stir zone of the 304 stainless steel, a refined grain structure with some features of dynamic recrystallization was evidenced. A thermomechanically-affected zone was characterized on the 304 steel side with features of dynamic recovery. In the other side of the stir zone, the hot deformation of the st37 steel in the austenite region produced small austenite grains and these grains transformed to fine ferrite and pearlite and some products of displacive transformations such as Widmanstatten ferrite and martensite by cooling the material after friction stir welding. The heat-affected zone in the st37 steel side showed partially and fully refined microstructures like fusion welding processes. The recrystallization in the 304 steel and the transformations in the st37 steel enhanced the hardness of the weld area and therefore, improved the tensile properties of the joint. - Highlights: ► FSW produced sound welds between st37 low carbon steel and 304 stainless steel. ► The SZ of the st37 steel contained some products of allotropic transformation. ► The material in the SZ of the 304 steel showed features of dynamic recrystallization. ► The finer microstructure in the SZ increased the hardness and tensile strength.

Comparison of the performance of concrete-filled steel tubular and hollow steel diagrid buildings
Peter, Minu Ann; S, Sajith A.; Nagarajan, Praveen
2018-03-01
In the recent construction scenario, diagrid structures are becoming a popular high-rise building structural system. Diagrid structures consist of diagonals in the perimeter and an interior core. The corner and interior vertical columns are not required due to the structural efficiency of diagrid structural systems. Steel and concrete are commonly used material for diagrid. An alternate material for diagrid is concrete-filled steel tube (CFST). CFST incorporates the advantages of both steel and concrete. In CFST, the inward buckling of the steel tube is effectively prevented by the filled concrete. The compressive strength of concrete increases due to the tri-axial state of stress in concrete induced by the steel tube. The longitudinal as well as lateral reinforcement to the concrete core is also provided by the steel tube. This paper compares the performance of CFST and steel diagrid buildings using linear static analysis. For this purpose, a 12 storey and 36 storey building are analysed using finite element method and CFST diagrid building is found to perform better.

2009-01-01
Nuclear power is an alternative energy source that is conducive to mitigate the environmental strains. The countries having nuclear power plants are encouraging research and development sector to find ways to construct safer and more economically feasible nuclear power plants. Modularization using Steel Plate Concrete(SC) structure has been proposed as a solution to these efforts. A study of structural modules using SC structure has been performed for shortening of construction period and enhancement of structural safety of NPP structures in Korea. As a result of the research, the design code and design techniques based on limit state design method has been developed. The design code has been developed through various structural tests and theoretical studies, and it has been modified by application design of SC structure for NPP buildings. The code consists of unstiffened SC wall design, stiffened SC wall design, Half-SC slab design, stud design, connection design and so on. The stiffened steel plate concrete(SSC) wall is SC structure whose steel plates with ribs are composed on both sides of the concrete wall, and this structure was developed for improved constructability and safety of SC structure. This paper explains a design application of SC structure for a sample building specially devised to reflect all of major structural properties of main buildings of APR1400. In addition, Stiffening effect of SSC structure is evaluated and structural efficiency of SSC structure is verified in comparison with that of unstiffened SC structure. (author)

Challenges in Special Steel Making
Balachandran, G.
2018-02-01
Special bar quality [SBQ] is a long steel product where an assured quality is delivered by the steel mill to its customer. The bars have enhanced tolerance to higher stress application and it is demanded for specialised component making. The SBQ bars are sought for component making processing units such as closed die hot forging, hot extrusion, cold forging, machining, heat treatment, welding operations. The final component quality of the secondary processing units depends on the quality maintained at the steel maker end along with quality maintained at the fabricator end. Thus, quality control is ensured at every unit process stages. The various market segments catered to by SBQ steel segment is ever growing and is reviewed. Steel mills need adequate infrastructure and technological capability to make these higher quality steels. Some of the critical stages of processing SBQ and the critical quality maintenance parameters at the steel mill in the manufacture has been brought out.

Full Text Available There was a pending influence of steel fiber on the strength and stiffness of composite steel–concrete slabs under statical short–time load. Steel profiled sheeting and steel fiber reinforced concrete were used for specimens. Four composite slabs were made. Experimental investigations into the behaviour and influence of steel fiber reinforced concrete in composite slabs were conducted. Transverse, longitudinal, shear deformation and deflection of the slab were measured. The results indicated that the use of steel fiber in composite slabs was effective: strength was 20–24 % higher and the meanings of deflections under the action of the bending moment were 0,6MR (where MR is the bending moment at failure of the slabs and were 16–18 % lower for slabs with usual concrete.

Full Text Available A high resolution regional chemistry-transport model has been used to study the distribution of exposure-plant response index (AOT40, Accumulated exposure Over a Threshold of 40 ppb, expressed as ppb h over the Indian geographical region for the year 2003 as case study. The directives on ozone pollution in ambient air provided by United Nations Economic Commission for Europe (UNECE and World Health Organization (WHO for vegetation protection (AOT40 have been used to assess the air quality. A substantial temporal and spatial variation in AOT40 values has been observed across the Indian region. Large areas of India show ozone values above the AOT40 threshold limit (3000 ppb h for 3 months. Simulated AOT40 values are found to be substantially higher throughout the year over the most fertile Indo-Gangetic plains than the other regions of India, which can have an adverse effect on plants and vegetation in this region. The observed monthly AOT40 values reported from an Indian station, agree reasonably well with model simulated results. There is an underestimation of AOT40 in the model results during the periods of highest ozone concentration from December to March. We find that the simulated AOT40 target values for protection of vegetation is exceeded even in individual months, especially during November to April. Necessary and effective emission reduction strategies are therefore required to be developed in order to curb the surface level ozone pollution to protect the vegetation from further damage in India whose economy is highly dependent on agricultural sector and may influence the global balance.

There are at least two reasons for undertaking a study of the political economy of India's electrical sector. Given that it is placed under the joint responsibility of the Centre and the States, its evolution reflects the relations between these two levels of the Indian federal system. Besides, the recent implementation of guidelines which have found favour with a large number of foreign countries could camouflage a subtle relationship with globalization which, in the case of India, is determined largely by the power equations within the country. Indeed, the reform path chosen integrates two elements: the argument that reforms have become necessary on account of the inefficiency of public sector organisations whose modes of functioning are inherited from the Indian bureaucratic system; secondly, there are political and economic forces who demand reforms as an essential element of their political strategy. In particular, contrary to the classical view in India that with liberalization there has been an emancipation of the States with regard to the Centre and the creation of expanding markets for foreign investments, the 'globalization' of the electricity sector, understood here as the opening up to the foreign private sector, could in reality be equated to a relative strengthening of the Centre vis-a-vis the States. It could also turn out to be to the advantage of some very local components, such as consumers' associations, whether rural or of local communities. (author)

The effect of the type of welding and fillers on crack resistance of welded joints high-strength steel EhP810 and its various compounds with steels EhP666, 08Kh18N10T has been studied. For the welding of steel EhP810 with steels EhP810, EhP666, 08Kh18N10T electron-beam, automatic, argon tungsten arc with non-consumable electrode with various fillers, as well as argon metal-arc welding with consumable electrode, were used. It is shown, that for a joint, made by electron-beam welding, parameters sigmasub(u), Ksub(IcJ), KCV are higher than for a joint of a similar phase structure made using filler wire EhP659-VI. It is explained by the fact, that during electron-beam welding joint metal refining takes place, which removes gases. In welded joints of chP810 steel, having joints with austenitic structure, characteristic of crack resistance Ssub(c) increases by more than 0.2 mm in contrast to two-phase joints, which conventional yield strength at 77 K exceeds 1000 MPa. It is worth mentioning, that for other classes of steels formation of two-phase structure of joint increases welded joint resistance to brittle fracture. It is possible to obtain the required structure of joint with assigned level of resistance to brittle fracture by means of the use of different fillers, optimum and welding procedure, regulating the part of the basic metal in joint content.

Background & objectives: Despite an impetus for strengthening public sector district hospitals for provision of secondary health care in India, there is lack of robust evidence on cost of services provided through these district hospitals. In this study, an attempt was made to determine the unit cost of an outpatient visit consultation, inpatient bed-day of hospitalization, surgical procedure and overall per-capita cost of providing secondary care through district hospitals. Methods: Economic costing of five randomly selected district hospitals in two north Indian States - Haryana and Punjab, was undertaken. Cost analysis was done using a health system perspective and employing bottom-up costing methodology. Quantity of all resources - capital or recurrent, used for delivering services was measured and valued. Median unit costs were estimated along with their 95 per cent confidence intervals. Sensitivity analysis was undertaken to assess the effect of uncertainties in prices and other assumptions; and to generalize the findings for Indian set-up. Results: The overall annual cost of delivering secondary-level health care services through a public sector district hospital in north India was 11,44,13,282 [US Dollars (USD) 2,103,185]. Human resources accounted for 53 per cent of the overall cost. The unit cost of an inpatient bed-day, surgical procedure and outpatient consultation was 844 (USD 15.5), i; 3481 (USD 64) and 170 (USD 3.1), respectively. With the current set of resource allocation, per-capita cost of providing health care through district hospitals in north India was 139 (USD 2.5). Interpretation & conclusions: The estimates obtained in our study can be used for Fiscal planning of scaling up secondary-level health services. Further, these may be particularly useful for future research such as benefit-incidence analysis, cost-effectiveness analysis and national health accounts including disease-specific accounts in India.

Since 1994, most of the major steel industries in Taiwan have installed portal monitor to detect the abnormal radiation in metal scrap feed. As a result, the discovery of NORM (Naturally Occurring Radioactive Material) has increased in recent years. In order to save the natural resources and promote radiation protection, an experimental melting process for the NORM contaminated steel scraps was carried out by the Institute of Nuclear Energy Research (INER) Taiwan, ROC. The experimental melting process has a pretreatment step that includes a series of cutting and removal of scales, sludge, as well as combustible and volatile materials on/in the steel scraps. After pretreatment the surface of the steel scraps are relatively clean. Then the scraps are melted by a pilot-type induction furnace. This experiment finally produced seven ingots with a total weight of 2,849 kg and 96.8% recovery. All of the surface dose rates are of the background values. The activity concentrations of these ingots are also below the regulatory criteria. Thus, these NORM-bearing steel scraps are ready for recycling.

Cyclical absenteeism among private sector, public sector and self-employed workers.
Pfeifer, Christian
2013-03-01
This research note analyzes differences in the number of absent working days and doctor visits and in their cyclicality between private sector, public sector and self-employed workers. For this purpose, I used large-scale German survey data for the years 1995 to 2007 to estimate random effects negative binomial (count data) models. The main findings are as follows. (i) Public sector workers have on average more absent working days than private sector and self-employed workers. Self-employed workers have fewer absent working days and doctor visits than dependent employed workers. (ii) The regional unemployment rate is on average negatively correlated with the number of absent working days among private and public sector workers as well as among self-employed men. The correlations between regional unemployment rate and doctor visits are only significantly negative among private sector workers. Copyright © 2012 John Wiley & Sons, Ltd.

This study examines the impacts of energy price changes resulting from different carbon-pricing policies on the competitiveness of selected US energy-intensive industries. It further examines possible industry responses, and identifies and provides a preliminary evaluation of potential opportunities to mitigate these impacts. The industry sectors investigated - steel, aluminum, chemicals and paper - are among the largest industrial users of fossil fuels in the US economy. The results of this examination show that climate policies that put a price on carbon could have substantial impacts on the competitiveness of US energy-intensive manufacturing sectors over the next two decades, if climate regulations are applied only in the United States, and no action is taken to invest in advanced low- and no-carbon technologies. The extent of these impacts will vary across industries, depending on their energy intensities, the mix of energy sources they rely on and how energy is used in production activities (heat and power, feedstock). Of relevance is also the speed and rigor with which industries adopt new technologies and retire (or replace) old ones. Other factors affecting these impacts include an industry's vulnerability to foreign imports and its ability to pass through cost increases to its customers in the face of international market competition.

Highlights: • The morphology of the corrosion of steel in cement paste was studied in situ. • During galvanostatic corrosion, carbon steel reinforcement corroded homogeneously. • On ferritic stainless steel, deep corrosion pits formed and caused wider cracks. • The measured rate of steel loss correlated well with Faraday’s law of electrolysis. - Abstract: In a X-ray microcomputed tomography study, active corrosion was induced by galvanostatically corroding steel embedded in cement paste. The results give insight into corrosion product build up, crack formation, leaching of products into the cracks and voids, and differences in morphology of corrosion attack in the case of carbon steel or stainless steel reinforcement. Carbon steel was homogeneously etched away with a homogeneous layer of corrosion products forming at the steel/cement paste interface. For ferritic stainless steel, pits were forming, concentrating the corrosion products locally, which led to more extensive damage on the cement paste cover

Fracture Mechanisms in Steel Castings

Full Text Available The investigations were inspired with the problem of cracking of steel castings during the production process. A single mechanism of decohesion - the intergranular one - occurs in the case of hot cracking, while a variety of structural factors is decisive for hot cracking initiation, depending on chemical composition of the cast steel. The low-carbon and low-alloyed steel castings crack due to the presence of the type II sulphides, the cause of cracking of the high-carbon tool cast steels is the net of secondary cementite and/or ledeburite precipitated along the boundaries of solidified grains. Also the brittle phosphor and carbide eutectics precipitated in the final stage solidification are responsible for cracking of castings made of Hadfield steel. The examination of mechanical properties at 1050°C revealed low or very low strength of high-carbon cast steels.

The mobilizations of key components from Primary Candidate Alloy (PCA) steel alloy have been measured with laboratory-scale experiments. The experiments indicate most of the mobilization from PCA steel is due to oxide formation and spalling but that the spalled particles are large enough to settle rapidly. Based on the experiments, models for the volatization of iron, manganese, and cobalt from PCA steel in steam and molybdenum from PCA steel in air have been derived.

OBJECTIVES: Whether the elevated risk of lung cancer observed among welders is caused by welding emissions or by confounding from smoking or asbestos exposure is still not resolved. This question was addressed in a cohort with a long follow-up and quantified estimates of individual exposure.......06-1.70)]. Among the stainless steel welders, the risk increased significantly with increasing accumulative welding particulate exposure, while no exposure-response relation was found for mild steel welders, even after adjustment for tobacco smoking and asbestos exposure. CONCLUSIONS: The study corroborates...... earlier findings that welders have an increased risk of lung cancer. While exposure-response relations indicate carcinogenic effects related to stainless steel welding, it is still unresolved whether the mild steel welding process carries a carcinogenic risk....
[In the America of mountain ranges, the brief summer of Indian agrarian movements (1970-1991)].
Le Bot, Y
1991-01-01
Indians actors in cultural, social, or political affairs at the regional or national level previously dominated by non-Indians. The peasant Indian movements are above all interested in issues of land and agrarian development, but they are not exclusively peasant. Some of the members are not agricultural workers, and their concerns exceed those of a simple peasant society. Diverse influences have been exercised on the formation and development of the movements. Progressive sectors of the Catholic Church were influential in almost all. The movements encountered opposition from class and national adversaries interested in maintaining the status quo, and also often experienced distrust, misunderstanding, or paternalistic attitudes on the part of nonpeasant organizations working for change. The future is uncertain for all of the movements, despite notable past successes for some of them.

Although the World Health Organization had recommended that every child be vaccinated for Hepatitis B by the early 1980s, large multinational pharmaceutical companies held monopolies on the recombinant Hepatitis B vaccine. At a price as high as USD$23 a dose, most Indians families could not afford vaccination. Shantha Biotechnics, a pioneering Indian biotechnology company founded in 1993, saw an unmet need domestically, and developed novel processes for manufacturing Hepatitis B vaccine to reduce prices to less than $1/dose. Further expansion enabled low-cost mass vaccination globally through organizations such as UNICEF. In 2009, Shantha sold over 120 million doses of vaccines. The company was recently acquired by Sanofi-Aventis at a valuation of USD$784 million. The case study and grounded research method was used to illustrate how the globalization of healthcare R&D is enabling private sector companies such as Shantha to address access to essential medicines. Sources including interviews, literature analysis, and on-site observations were combined to conduct a robust examination of Shantha's evolution as a major provider of vaccines for global health indications. Shantha's ability to become a significant global vaccine manufacturer and achieve international valuation and market success appears to have been made possible by focusing first on the local health needs of India. How Shantha achieved this balance can be understood in terms of a framework of four guiding principles. First, Shantha identified a therapeutic area (Hepatitis B) in which cost efficiencies could be achieved for reaching the poor. Second, Shantha persistently sought investments and partnerships from non-traditional and international sources including the Foreign Ministry of Oman and Pfizer. Third, Shantha focused on innovation and quality - investing in innovation from the outset yielded the crucial process innovation that allowed Shantha to make an affordable vaccine. Fourth, Shantha

2014-01-01
The concept of cold-formed light steel framing construction has been widespread after understanding its structural characteristics with massive research works over the years. Connection serves as one of the important elements for light steel framing in order to achieve its structural stability. Compared to hot-rolled steel sections, cold-formed steel connections perform dissimilarity due to the thin-walled behaviour. This paper aims to review current researches on cold-formed steel connections, particularly for screw connections, storage rack connections, welded connections, and bolted connections. The performance of these connections in the design of cold-formed steel structures is discussed. PMID:24688448

The USSR steel EP-838 is a high-manganese, low-nickel steel that also has lower chromium and molybdenum than type 316 stainless steel. Tensile specimens of 20%-cold-worked EP-838 and type 316 stainless steel were irradiated in the High Flux Isotope Reactor (HFIR) at the coolant temperature (approx.=50 0 C). A displacement damage level of 5.2 dpa was reached for the EP-838 and up to 9.5 dpa for the type 316 stainless steel. Tensile tests at room temperature and 300 0 C on the two steels indicated that the irradiation led to increased strength and decreased ductility compared to the unirradiated steels. Although the 0.2% yield stress of the type 316 stainless steel in the unirradiated condition was greater than that for the EP-838, after irradiation there was essentially no difference between the strength or ductility of the two steels. The results indicate that the replacement of the majority of the nickel by manganese and a reduction of chromium and molybdenum in an austenitic stainless steel of composition near that for type 316 stainless steel has little effect on the irradiated and unirradiated tensile properties at low temperatures.

Pakistan's IT industry is currently one of the top performers as compared to other industrial sectors within Pakistan. As per the findings of Ahsan (2008), despite the fact that Pakistan's IT industry is competitive (with respect to other industries within Pakistan), its true potential is yet to be unfolded. Ahsan (2008); states that Pakistan's so called competitive IT industry has to be in lined with the international performers (Particularly South Asian economies). A simple proof of this statement can be obtained from the fact that Pakistan's general economy is 1/5 of Indian economy. This must be true for IT sector of both the economies, which, unfortunately is not the case because Pakistan's IT sector is currently 1/27 of the Indian IT Sector. Ahsan (2008) believes that partial reason of this unwanted difference may be revenue models, business practices and political situations of the two countries. Other than these reasons Ahsan (2008) believes that several soft issues are also responsible for this industrial difference. Out of these soft issues 'motivation' is one such important factor. The role of motivation as an imperative soft issue for revitalizing workforce can also be reproduced for the discussion concerning the role of 'basic employee satisfaction' as an organisation's productivity and quality enhancement tool. Employees, being an integral asset of the organizations, impact organizations in accomplishment of their objectives. The impact of employee satisfaction in software industry of Pakistan is relatively less known but plays significant role. This paper analyzes the major causes of employee satisfaction and the impact of employee satisfaction on quality and productivity dimensions (particularly) in the IT organizations in Pakistan. This research presents analysis of 'Employee Satisfaction' for IT sector of Pakistan. The study not only explores but also presents detailed explanation and analysis of the subject area for the IT industry of Pakistan by

Aimed to optimize the hot working conditions for high chromium stainless steels the experiments were carried in the temperature range of 800-1300 deg C using hot torsion tests and cylindrical specimens of ferritic and ferritic-martensitic steels 08Kh13, 12Kh13, 20Kh13, 30Kh13 and 40Kh13. Testing results showed that steel plasticity varies in a wide range depending on carbon content. Steels of lesser carbon concentration (08Kh13 and 12Kh13) exhibit a sharp increase in plasticity with a temperature rise, especially in the interval of 1200-1250 deg C. Steels 20Kh13 and 30Kh13 display insignificant plasticity increasing, whereas plastic properties of steel 40Kh13 increase noticeably in the range of 1000-1300 deg C. It is shown that optimal hot working conditions for specific steel must be selected with account of steel phase composition at high temperatures

The trend and the development of light-water reactor applications are described. The fundamental operating parameters of the WWER type reactors are indicated. The effect is discussed of neutron radiation on reactor structural materials. The characteristics are described of steel corrosion due to the contact of the steel with steam or sodium in the primary coolant circuit. The reasons for stress corrosion are given and the effects of radiation on corrosion are listed. The requirements and criteria are given for the choice of low-alloy steel for the manufacture of pressure vessels, volume compensators, steam generators, cooling conduits and containment. A survey is given of most frequently used steels for pressure vessels and of the mechanical and structural properties thereof. The basic requirements for the properties of steel used in the primary coolant circuit are as follows: sufficient strength in operating temperature, toughness, good weldability, resistance to corrosion and low brittleness following neutron irradiation. The materials are listed used for the components of light-water and breeder reactors. The production of corrosion-resistant steels is discussed with a view to raw materials, technology, steel-making processes, melting processes, induction furnace steel-making, and to selected special problems of the chemical composition of steels. The effects are mainly discussed of lead, bismuth and tin as well as of some other elements on hot working of high-alloy steels and on their structure. The problems of corrosion-resistant steel welding and of pressure vessel cladding are summed up. Also discussed is the question of the concept and safeguards of the safety of nuclear installation operation and a list is presented of most commonly used nondestructive materials testing methods.

With growing demand for high esthetic standards, dentists must understand patient perception and incorporate their preferences into treatment. However, little is known about how cultural and ethnic differences influence esthetic perception. The purpose of this study was to determine whether differences in ethnic background, including the possibility of assimilation, affected a layperson's perception of esthetic and smile characteristics. A survey was developed containing images that were digitally manipulated into a series of barely perceptible steps, changing 1 smile parameter to form a strip of images that displayed that parameter over a wide range. Data were collected with a customized program which randomly displayed a single image and allowed the subject to use the mouse to adjust an on-screen slider according to displayed instructions, that is, "Please move the slider to select the image you find to be most ideal"; or "Please move the slider to select the first image that you find unattractive." A convenience sample (n=288) comprised of U.S. whites, U.S. Asian Indians, and Indians living in India was surveyed. This sample provided a power of .86 to detect a difference of ±1.5 mm. Subjects evaluated images showing the smile arc, buccal corridor, gingival display, vertical overlap, lateral incisal step, maxillary midline to midface, and maxillary to mandibular midline. Rater reliability was assessed with the Fleiss-Cohen weighted Kappa (Kw) statistic and corresponding 95% confidence interval after each question was repeated in a random sequence. Choice differences due to ethnicity were assessed with a multiple randomization test and the adjusted P value with the step-down Bonferrroni method of Holm (α=.05). The Kw for the 17 variables in all 3 groups ranged from 0.11 for ideal vertical overlap to 0.64 for ideal buccal corridor space. Overall reliability was fair to moderate. Differences attributed to ethnicity were demonstrated between the Asian Indians and U

The People of India database of the Anthropological Survey of India documents 631 cultural, ecological, and economic traits of the 4635 communities to which the entire Indian population is assigned. Focusing on 1342 communities of South India, we looked for correlates of low (1 or 2 children) and high (4 or more children) desired family size (DFS) reported as the norm for any given community by key informants. We found 10 cultural and 18 economic traits to be significantly correlated to high DFS and 21 cultural and 9 economic traits to low DFS. The economic traits so identified are compatible with high family size being desired by parents who have little capability of investing in quality of offspring, but whose children contribute economically from an early age. In contrast, communities desiring low family size are part of the modern intensive agriculture/organized industry/services sector and invest heavily in educating their children. A composite index based on 27 economic traits (CEI) has a high predictive value with respect to the DFS for the entire set of 4635 Indian communities. The 31 cultural traits highly correlated to high or low DFS constitute 5 clusters that can be identified as characterizing scheduled tribes, scheduled castes, rural and landless lower castes, urban upper castes, and Moslems. Whereas economic traits have similar influence on DFS within each of these ethnic categories, Moslems demonstrate a significantly higher DFS for lower values of CEI.

This study performs an integrated assessment of new technology adoption in the steel industry. New coke, iron, and steel production technologies are discussed, and their economic and environmental characteristics are compared. Based upon detailed plant level data on cost and physical input-output relations by process, this study develops a simple mathematical optimization model of steel process choice. This model is then expanded to a life cycle context, accounting for environmental emissions generated during the production and transportation of energy and material inputs into steelmaking. This life-cycle optimization model provides a basis for evaluating the environmental impacts of existing and new iron and steel technologies. Five different plant configurations are examined, from conventional integrated steel production to completely scrap-based operations. Two cost criteria are used to evaluate technology choice: private and social cost, with the latter including the environmental damages associated with emissions. While scrap-based technologies clearly generate lower emissions in mass terms, their emissions of sulfur dioxide and nitrogen oxides are significantly higher. Using conventional damage cost estimates reported in the literature suggests that the social costs associated with scrap-based steel production are slightly higher than with integrated steel production. This suggests that adopting a life-cycle viewpoint can substantially affect environmental assessment of new technologies. Finally, this study also examines the impacts of carbon taxes on steel production costs and technology choice.

Between 1996 and 2006, CO 2 emissions in Taiwan increased by approximately 60%, with the industrial sector accounting for 50% of that increase. Among all industrial sectors, iron and steel, petrochemicals, electronics, textiles, pulp and paper and cement accounted for approximately three-quarters of the total industrial CO 2 emissions. Identifying the driving forces behind increased CO 2 emissions in these six sectors could be valuable for the development of effective environmental policy. This study used two-tier KLEM input–output structural decomposition analysis (I-O SDA) to analyze the factors that lead to changes in CO 2 emissions. Empirical results obtained in Taiwan reveal that increased exports level and elevated domestic autonomous final demand level were the main reasons for increases in CO 2 emissions. Technological changes in materials and labor tended to decrease CO 2 emissions, while the power generation mix contributed significantly to the increase. Relevant strategies for reducing CO 2 emissions from energy-intensive sectors are also highlighted. - Highlights: • Identifying the driving forces behind increased CO 2 emissions is important. • This study uses two-tier KLEM I-O SDA to analyze the changes in CO 2 emissions. • Three issues are identified to achieve future CO 2 emissions reduction in Taiwan

India is a vast country depicting wide social, cultural and sexual variations. Indian concept of sexuality has evolved over time and has been immensely influenced by various rulers and religions. Indian sexuality is manifested in our attire, behavior, recreation, literature, sculptures, scriptures, religion and sports. It has influenced the way we perceive our health, disease and device remedies for the same. In modern era, with rapid globalization the unique Indian sexuality is getting diffused. The time has come to rediscover ourselves in terms of sexuality to attain individual freedom and to reinvest our energy to social issues related to sexuality.

Advanced high-strength steels offer a great potential for the further development of automobile bodies-in-white due to their combined mechanical properties of high formability and strength. They represent the first choice in material selection for strength and crash-relevant parts with challenging geometries. The intensive development of multiphase steels by ThyssenKrupp Steel has led to hot dip galvanizing concepts with an outstanding forming potential. Hot rolled, hot dip galvanized complex-phase steels are currently produced in addition to cold rolled dual phase (DP) and retained austenite (RA) or transformation induced plasticity (TRIP) steels. New continuously annealed grades of steel are being developed with tensile strength levels of up to 1000 MPa in combination with sufficient ductility for the high demands of structural automobile components. These steels make use of the classic advantages of microalloying as well as the principles of DP steels and RA / TRIP steels. Further improvement of properties will be reached by the new class of high manganese alloyed steels. (orig.)

With the continuous urbanization and industrialization in the world, energy saving and greenhouse gas (GHG) emission reduction have been serious issues to be addressed, for which heat recovery from traditional energy-intensive industries makes up a significant strategy. Here we report a novel approach to extract the waste heat and iron from high temperature steel slags (1450–1650 oC) produced in the steel industry, i.e., integration of coal gasification and steel slag treatment. Both the thermodynamics and kinetics of the pertinent reactions were identified. It was clarified that the kinetic mechanism for gasification varied from A2 model to A4 model (Avrami-Erofeev) in the presence of slags. Most importantly, the steel slags acted not only as good heat carriers but also as effective catalysts where the apparent activation energy for char gasification got remarkably reduced from 95.7 kJ/mol to 12.1 kJ/mol (A2 model). Furthermore, the FeO in the slags was found to be oxidized into Fe3O4, with an extra energy release, which offered a potential for magnetic separation. Moreover, based on the present research results, an emerging concept, composed of multiple industrial sectors, was proposed, which could serve as an important route to deal with the severe environmental problems in modern society.

Steels are alloys of iron and carbon, widely used in construction and other applications. The evolution of steel microstructure through various heat treatment processes is an important factor in controlling properties and performance of steel. Extensive experimentations have been performed to enhance the properties of steel by customizing heat treatment processes. However, experimental analyses are always associated with high resource requirements in terms of cost and time. As an alternative solution, we propose an image processing-based technique for refinement of raw plain carbon steel microstructure images, into a digital form, usable in experiments related to heat treatment processes of steel in diverse applications. The proposed work follows the conventional steps practiced by materials engineers in manual refinement of steel images; and it appropriately utilizes basic image processing techniques (including filtering, segmentation, opening, and clustering) to automate the whole process. The proposed refinement of steel microstructure images is aimed to enable computer-aided simulations of heat treatment of plain carbon steel, in a timely and cost-efficient manner; hence it is beneficial for the materials and metallurgy industry. Our experimental results prove the efficiency and effectiveness of the proposed technique.

Purpose: This study examined the relationship of the organizational role stress: Role overload, role self-distance, and role stagnation with job satisfaction and turnover intention with a sample of banking employees in India. Methodology: In this research, we used the RODS scale developed by Prohit and Pareek (2010) for measuring occupational role scale. The reliability of the scale came out to be 0.71. Findings: The majority of employees of all ranks, in both private and public sector banks, suffer from high role stress of all types. It was found that role overload and role stagnation are inversely associated with banking employees' job satisfaction. Private sector bank employees have more role stress and more unsatisfied than employees of public sector banks. Employees Turnover intention was found to be positively impacted by job satisfaction, contrary to many other studies. Possible reasons have been suggested. Job satisfaction was found to play a partial mediating role in the relationship between role overload and turnover intention with 40% mediation. Further, employees with longer tenure (work experience) have less role stress and are more satisfied. Originality: This study is unique in the sense there is hardly any study linking role stress to job satisfaction and turnover intention, specially in Indian context. PMID:29200554

Full Text Available Indian music has a very long, unbroken tradition and is an accumulated heritage of centuries. Music in India was popular among all the sections of society and intertwined in life and culture from birth to death. Indian music was formed with the evolution of ancient religious and secular music. The Indian culture absorbed all the best that was brought by other nations in the process of historical development. The Indian music is quite diverse: there are classical instrumental and vocal works and traditional singing of sacred hymns, folk songs and music of different nations. In contrast to the music scholarship, where typically image is a certain regularity, discipline and harmony, beauty of the traditional Indian music in the free improvisation, which is used by the performer. Listening carefully of this music, the man in a new world, a different sounds and explore a different idea of music for himself. The aim of the Indian music, unlike European musical culture define, explore, create and move depths to people's moods. And the Indian instruments is a miracle, that could reflect all these philosophical and aesthetic views. Along with the vocal art, this musical tradition has rich variety of melodic and rhythmic instruments.

Occupational noise-induced hearing loss in Indian steel industry workers: an exploratory study.
Singh, Lakhwinder Pal; Bhardwaj, Arvind; Deepak, Kishore Kumar
2013-04-01
The present study focused on exploring the current level of hearing protection and subsequently determined the prevalence of occupational noise-induced hearing loss among casting and forging industry workers. The casting and forging industry provides employment to a significant portion of the population. The level of hearing protection was assessed through questionnaire survey of 572 workers. Out of these workers, 165 and another control group of 57 participants were assessed by formal audiometry. Audiometric tests were conducted at frequencies of 1.0 KHz to 8.0 KHz.The occurrence of hearing loss was determined on the basis of a hearing threshold level with a low fence of 25 dB. Student's test and ANOVA were used to compare the various groups; a p value steel industry are highly exposed to occupational noise. The majority of workers are not protected from noise-induced hearing loss. There is a need to provide special ear protectors for workers engaged in forging. A complete hearing protection program, including training, audiometry, job rotation, and the use of hearing protection devices, needs to be introduced.

Full Text Available Medication nonadherence is a known problem after renal transplantation and can vary from one setting to another. Since it can lead to negative outcomes, it is important to develop intervention strategies to enhance adherence in a given setting using determinants identified through exploratory studies. We explored nonadherence in renal transplant recipients. A longitudinal survey was done with adult renal transplant recipients at a tertiary care public and two private hospitals of Kolkata. Subjects were followed-up for 1 year. After screening for medication adherence status by the four-item Morisky Medication Adherence Scale, those admitting to potential nonadherence were probed further. A patient was deemed to be nonadherent if failing to take medicines on appointed time (doses missed or delayed by more than 2 h more than three times in any month during the observation period. A pretested questionnaire was used to explore potential determinants of nonadherence. Data of 153 patients recruited over a 2-year were analyzed. The extent of nonadherence with immunosuppressant regimens was about 31% overall; 44% in the public sector and 19% in the private sector (P < 0.001. Nonadherence with other medication was around 19% in both the sectors. Several potential demographic, socioeconomic and psychosocial determinants of nonadherence were identified on univariate analysis. However, logistic regression analysis singled out only the economic status. This study had updated the issue of nonadherence in renal transplant recipients in the Indian setting. Strategies to improve medication adherence can be planned by relevant stakeholders on the basis of these findings.

In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80 % by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. The overall objective of the work presented in this thesis is to provide a technology-based perspective on the feasibility of significant reductions in CO{sub 2} emissions in the EU power and industrial sectors, with the emphasis on expected turnover in the capital stock of the existing infrastructure. Three sectors of industry are included: petroleum refining; iron and steel production; and cement manufacturing. The analysis is based on a thorough description and characterization of the current industry infrastructure and of the key mitigation technologies and measures in each sector. The analysis comprises investigations of how specific factors, such as the age structure of the capital stock, technology and fuel mix, and spatial distribution of the plant stock, contribute to facilitating or hindering the shift towards less-emission-intensive production processes. The results presented here are the synthesis of the results described in the following three papers: Paper I investigates the potential for CCS in industrial applications in the EU by considering branch- and plant-specific conditions; Paper II assesses strategies for CO{sub 2} abatement in the European petroleum refining industry; and Paper III explores in a scenario analysis the limits for CO{sub 2} emission abatement within current production processes in the power and industrial sectors. Together, the three papers provide a comprehensive assessment of the roles of technologies and measures that are commercially available today, as well as those of emerging technologies that are still in their early phases of development. The results presented in Paper III show that the EU goal for emissions reductions in the sectors covered by the EU ETS, i
