This paper discusses extension of TAM for implementing ERP in a public sector undertaking in a public sector undertaking in India. TAM is used to find determinants that need to be considered for IS implementation at individual level. In this research, we have used primary survey to find different factors that impacted ERP implementation at an organisation level and then mapped to determinants in TAM. The framework developed from this research can be tried in other organisations to fine tune the approach.

Socio-Economic Impact of Industrialisation and Mining on the Local Population: A Case Study of Nalco Industrial Area, Koraput

National Aluminium Company (NALCO), Damanjodi is a govt. owned Navaratna company located in the major bauxite mining district of Odisha. The vast majority of the local population around NALCO are SCs and STs and most of them are employees of the company. On the contrary, it has a displacement effect on the tribals and creates water, air and sound pollution. Considering the above, this paper attempts to explain the significance of industrialisation and its impact on the local economic development through a case study in three peripheral villages of NALCO industrial area. In view of the specificity of the topic, we relied on primary data. The relevant information has been elicited from 100 residents of three surrounding villages of NALCO namely Kapsiput, Analabadi and Goudaguda through a special questionnaire. The findings reflect both positive and negative effects of mining, refinery, aluminium smelter and industrial effluents of NALCO on human and ecological health, pattern of livelihood, income, education and settlement of local population etc. and, finally, it suggests alternatives and improvements to prevent environmental and health degradation and, to actively promote education, health and economic development around industrial sites.

Selling Family Gold for Pleasure Spending: The Case of Public Sector Stake-Sale in India

India’s Finance Minister (FM), Arun Jaitley kick started the public sector disinvestment with 5 per cent stake sale in Steel Authority of India (SAIL) on 5.12.2014. 200 million shares were sold to the investors. The offer generated a lot of interest among the retail investors and was over subscribed by one-and-a-half times. It fetched Rs 1700 crore for the Government of India (GOI) to go one step closer in meeting disinvestment target for the year 2014-15. Other companies like Coal India, Oil and Natural Gas Corporation (ONGC), and National Hydro-power Corporation (NHPC) are on the agenda. The FM also targets to sale residual shares in Hindustan Zinc Ltd and Bharat Aluminum Company (BALCO) to the present majority stake-holder, Anil Agrawal. The money fetched from disinvestment would be used for keeping the fiscal deficit within 4.1 per cent of GDP. Although it is important to keep fiscal deficit in tight control, it should have been done by reducing non-plan expenditure. This paper aims to show the actual value of these units for the self-reliance of India and the meager amount for which these jewels are going to be doled out to private operators. It gives a few suggestions to protect the interest of retail investors in the stock market. The paper also tries to find research gaps how the retail investors’ interest can be protected comprehensively from stock market fluctuations in future.

Control of Temperature and Aluminum Fluoride Concentration Based on Model Prediction in Aluminum Electrolysis

The temperature and the aluminum fluoride (AlF3) concentration of electrolyte greatly affect the current efficiency and energy consumption in aluminum electrolysis. This paper developed a new kind of algorithm to control the temperature and AlF3concentration of electrolyte for 300 kA prebake aluminum production cells by altering the setting cell voltage and the AlF3adding rate. One is liquidus model which can be used to calculate AlF3concentration of electrolyte by some technical parameters and target superheat and the other is the temperature models which can determine the required cell voltage by the technical parameters and target temperature. Consequently, the AlF3addition rate can be decided by the AlF3concentration. The temperature and AlF3concentration of electrolyte in the production are measured and the differences between the measurement and the corresponding calculation are used as feedback to correct the model. The coefficients in the model are also revised according to the external conditions. This system has been used in an aluminum company for 2 years. Both the temperature and the AlF3concentration of electrolyte can be controlled as required and the energy consumption of the aluminum production was much decreased.

The Analysis of Stability of Mine's Tailing Dam Based on the FLAC<sup>3D</sup>

Tailings dam is an important part of engineering construction of tailings pond. Stability analysis of tailing dam is of great significance, because it is the significant security risk of the project of tailings. FLAC3D program which based on Lagrange algorithm is especially suitable for solving the nonlinear large deformation problems in rock and soil mechanics engineering. After the adequate mastery of the soil layer structure, the physical and mechanical properties and the determination of the calculation parameters, the engineering software of FLAC3D and the numerical analysis method are utilized to analyze the integral stability of the tailing dam of Guangxi Xinfa Aluminum Company in Jingxi county. It can provide a scientific basis for the stability analysis of engineering construction of another tailing pond.

Piecewise exponential models to assess the influence of job-specific experience on the hazard of acute injury for hourly factory workers

BackgroundAn inverse relationship between experience and risk of injury has been observed in many occupations. Due to statistical challenges, however, it has been difficult to characterize the role of experience on the hazard of injury. In particular, because the time observed up to injury is equivalent to the amount of experience accumulated, the baseline hazard of injury becomes the main parameter of interest, excluding Cox proportional hazards models as applicable methods for consideration.MethodsUsing a data set of 81,301 hourly production workers of a global aluminum company at 207 US facilities, we compared competing parametric models for the baseline hazard to assess whether experience affected the hazard of injury at hire and after later job changes. Specific models considered included the exponential, Weibull, and two (a hypothesis-driven and a data-driven) two-piece exponential models to formally test the null hypothesis that experience does not impact the hazard of injury.ResultsWe highlighted the advantages of our comparative approach and the interpretability of our selected model: a two-piece exponential model that allowed the baseline hazard of injury to change with experience. Our findings suggested a 30% increase in the hazard in the first year after job initiation and/or change.ConclusionsPiecewise exponential models may be particularly useful in modeling risk of injury as a function of experience and have the additional benefit of interpretability over other similarly flexible models.

‘The salvation of this district and far beyond’: Aluminium Production and the Politics of Highland Development

Giving evidence before the House of Commons sub-committee considering the Lochaber Water Power Bill of 1921 – the statutory instrument for the establishment of the British Aluminium Company Ltd’s third Highland aluminium smelter and hydro-electric power scheme – the former Provost of Fort William, Colin Young, declared: ‘I am a whole hearted supporter of this scheme for in it I see the salvation of this district and far beyond.’1 British Aluminium’s other developments in the west Highlands – their two other smelters at Foyers and Kinlochleven (opened respectively in 1896, and between 1907 and 1909), as well as the Company’s large estates, housing and hydro-electric schemes – had already amply demonstrated both the profound economic and social impact both locally and on the region as a whole. This article is principally concerned with exploring the economic and social significance of the aluminium industry to the Highlands and Islands, and its importance to the wider political economy of regional development. These developments and activities are considered in relation to corporate ‘social action’ and political activity, appraising the motivations and strategies affecting the wider activities of the British Aluminium Company (BACo) in the region. The negotiations are examined within the context of a ‘moral economy’, alongside the political economic, balancing moral judgements, and local customs and norms, against commercial deliberations

Rivers Run Through It

This essay reviews three books illustrating recent trends in Canadian environmental history. All three books deal with the relationship of human beings to rivers, but each from a different perspective. The first book, written by Christopher Armstrong, Matthew Evenden, and H.V. Nelles, examines the Bow River (Alberta) in the most comprehensive way since the beginning of human settlement. The second book, by Michèle Dagenais, depicts the numerous, and often conflictual, links Montréal has with the St. Lawrence River since 1800. In the last book, David Massell focuses on the transformation of the Peribonka River made by the Aluminum Company of Canada Ltd. (Alcan), and the social and political consequences this transformation generated.

Cryolite, the Canadian aluminium industry and the American occupation of Greenland during the Second World War

On 9 April 1940 Germany invaded Demark. Instantly the fate of Greenland, a Danish colony, was thrust into limbo. The Aluminium Company of Canada (Alcan) had particularly self-interested concerns in the future of the island. In 1940, Greenland was home to the world’s only working mine and known major deposit of natural cryolite, a mineral essential to the aluminium smelting process. The Danish had been in control of cryolite mining and refining since its initial commercial development and a German-occupied Denmark posed a major threat to the global cryolite supply. This paper discusses the ways in which cryolite and the Canadian aluminium industry influenced Canada’s role in the genesis of the American occupation of Greenland and considers lessons that can be gleaned from the past for contemporary Greenlandic industry and society.

Project selection and prioritisation in Iranian Aluminium Company (IRALCO)

This study proposed a method which is much innovative for the project selection, the proposed method is the one which is untouched by many due to the certain misbelieves and the comparison with the alternates available. The main aim and the objectives in the study are to analyse the analytic hierarchy process (AHP) methods and to identify the themes, ideas and the areas being investigated in the study. The AHP is the one content which is much trendy in current era so the idea and the areas of investigation play a significant role. The analytic hierarchy process (AHP) make use of many hierarchical structures to position compare criteria and option in categorise to give maintain in decision making responsibilities. The boundary of the study deals with the AHP as the process itself with much preference given to the hierarchy models and the sub hierarchy models associated, the criteria and the sub-criteria related. The methodology of the study mainly deals with the strategic objective; include the quantitative method in the selection of the process. The new framework combines the two main approaches; project selection models and AHP technique. It is powerful and useful tool which should be used to convert strategy into action. Key words: Project selection and prioritisation, financial and non-financial models, multi criteria decision making, analytical hierarchy process.

UTILIZATION OF ALUMINUM DROSS TAILINGS TO PRODUCE A COAGULANT

Abstract Highly pure aluminum sulphate is an important chemical from industrial point of view , especially for paper makers. It is also used for water treatments, dyeing of cloth, fire proofing fabrics, leather tanning and for cellulosic insulations. Dross is an industrial waste from aluminum production factories and is of wide varieties , being a problematic issue for aluminum producing factories, such as Egyptian Aluminum company at Nag Hammadi which produces hudge amounts daily of such wastes needing either marketing , landfilling or processing to useful products . The present investigation exposes one of processing ideas of changing aluminum content of such waste either to impure aluminum sulphate solution, pure aluminum sulphate solution or aluminum sulphate in solid form, using simple treatments at low temperatures so as to increase benefits and decrease costs of transformation. Laboratory studies proved possibility of such transformations at temperatures ranging from 70oC to 100oC, using sulphuric acid. These results had been scaled-up for an engineering scope by design of a semi-pilot scale sediment where laboratory sedimentation results of obtained aluminum sulphate had been tried . Results of present investigation represent a step for environmental friendship by processing daily dross waste at Nag Hammadi Egyptalum company, by increasing income from selling such a waste to other purchasers ; whereby the waste dross will become an aluminum by-product .

Hydroelectricity, it seems, has powered much of twentieth‐century Quebec history. Today the government‐owned Hydro Quebec is the largest producer of hydroelectricity in the world; the main developer of hydropower in the region of eastern Quebec under consideration, the Aluminum Company of Canada (now Rio Tinto Alcan), is the world's largest producer of aluminum. But the story is more than one of scale. “Hydropolitics” contributes to many of the narratives that combine to explain the province's history. David Massell effectively explores the intersection of many of them. He focuses on opposite extremes: on one hand, the elite corporate and state actors and, on the other, those whose lives were most severely affected, the indigenous Innu (or Montagnais). Each was almost entirely ignorant of the other, a fact that only adds to the drama and significance of this story. Massell examines the Saguenay River and North Shore watersheds north of Quebec City, a region—in the eyes of business and government—of extraordinary potential for power generation. Already in the 1920s, in a move symbolic of the Quebec Liberal government's subservience to American business, James Duke was allowed to convert Lac Saint‐Jean into a massive reservoir, flooding farmlands without notice or compensation. But it was the inexhaustible wartime demand for aluminum, the reduction of which requires vast amounts of power, that would transform a much broader landscape. Overnight, Canada, and particularly the Saguenay, became America's prime source of aluminum ingot. This required the transformation of the watershed as a whole as new dams were built, particularly along the Peribonka River, to create large reservoirs to ensure a steady and predictable supply of water for the new and expanded hydroelectric facilities. As well, it meant the rapid expansion in the size and power of Alcan, the Aluminum Company of Canada.

Six Sigma methodology applications within aluminium company

This study proposes a new analysis and practice of Six Sigma methodology to define, measure, analyse, innovate and control (DMAIC). Six Sigma is a well-known concept who means the perfection: a process of production to three sigma makes 3.4 defaults/million unit, whereas Six Sigma means for us the perfection. We used it now to mean the type of specialised training aiming at the attack of very high objectives for processes improvement. The method Six Sigma is a method of continuous improvement and elimination of non-quality, passing by six stages or cycle DMAIC carried out by a team of project. In this paper, we propose a new practice of Six Sigma for reduction and optimisation of non-conformity for aluminium company.

Characterization of Spent Prebaked Aluminium Carbon Anode as a Source of Fuel for Foundrymen

Small scale foundries in Ghana are in search of a suitable coke for their foundry operations since there is no coal mine in Ghana. Two grades of spent prebaked aluminium carbon anodes (herein referred to as grade P and grade K), which are remnants from the aluminium electrolysis at Volta Aluminum Company (VALCO), an aluminium smelting company in Ghana, have been characterized to assess their quality and use as foundry coke. Proximate analysis and X-ray diffraction techniques have been used for their quality assessments. Coke grade P had lower moisture content, volatile matter and ash content compared to grade K. In both grades, sulphur and phosphorus contents were within requirements of a quality foundry coke. However, the volatile matter and ash contents of both grades were not satisfactory. Fixed carbon contents in both grades were below that of a quality foundry coke. Carbon structure of coke found in both grades is crystalline in nature. The crystalline width, Lc, was calculated to be 4.05 A and 5.12 A for grade K and P, respectively.

Surface treatment of new type aluminum lithium alloy and fatigue crack behaviors of this alloy plate bonded with Ti–6Al–4V alloy strap

Samples consisting of new aluminum lithium alloy (Al–Li alloy) plate developed by the Aluminum Company of America and Ti–6Al–4V alloy (Ti alloy) plate were investigated. Plate of 400mm×140mm×2mm with single edge notch was anodized in phosphoric solution and Ti alloy plate of 200mm×20 (40) mm×2mm was anodized in alkali solution. Patterns of two alloys were studied at original/anodized condition. And then, aluminum alloy and Ti alloy plates were assembled into a sample with FM 94 film adhesive. Fatigue crack behaviors of the sample were investigated under condition of nominal stress σ=36MPa and 54MPa, stress ratio of 0.1. Testing results show that anodization treatment modifies alloys surface topography. Ti alloy bonding to Al–Li alloy plate effectively retards crack growth than that of Al–Li alloy plate. Fatigue life of sample bonded with Ti alloy strap improves about 62.5% than that of non-strap plate.

An evaluation of successful reclamation of bauxite residue through afforestation activities in south India

The present article is based on the results of a pilot project implemented to improve the physico chemical characteristics of bauxite residue (red mud) in order to make it suitable for rehabilitation through afforestation activities. Prior to interventions, extensive experimentation on various reclamation trials involving combinations of soil amenders along with bacteria and mycorrhizae and selection of suitable tree and grass species was undertaken at the nursery stage for one year. During this period, five tree species and four grass/legume species were selected for afforestation program. Of the selected five tree species, Prosopis juliflora, Acacia nilotica and Pongamia pinnata responded well in combination with 55% red mud +25% FYM + 15% gypsum + 5% vegetative dry dust + bacteria + mycorrihzae, while other two species, Melia azedarach and Acacia tortilis did not survive and thus were replaced by Albizia lebbek and Leucaena leucocephala during pilot implementation in 1.08 ha research plot of red mud of Hindustan Aluminium Company Limited (HINDALCO) at Belgaum, Karnataka, South India. Among the grass and legume species, all the selected four species namely: Brachiaria mutica, Brachiaria decumbens, Stylosanthes scabra and Sesbania sesban responded well at the nursery stage and thus were experimented at the research plot along with the tree plantation. Continuous monitoring on growth pattern of tree and grass species, and soil characteristics revealed remarkable changes in the physico chemical properties of red mud. Apart, toxicity of the planted species and other naturally grown herbaceous flora on the research plot of red mud was also tested for their edibility properties and the results were found encouraging. Key words: Red mud, bacteria, mycorrhizae, tree species.

Caracterização sócio-ambiental da comunidade de Coquilho na zona rural de São Luís-MA

O saneamento ambiental inadequado é uma das principais causas de degradação do meio ambiente e de proliferação de doenças no Brasil, sendo responsável por diversas internações hospitalares implicando em gastos públicos. A comunidade Coquilho com cerca de 611 famílias distribuídas em 475 ha, constituídas por ex-moradores pobres descendentes dos ocupantes da área onde hoje está instalada uma empresa de siderurgia de alumínio. Nesse sentido, buscou-se caracterizar os aspectos sócio-ambientais da comunidade, destacando seu modo de vida enfatizando seus problemas ambientais. Pode-se constatar que esta comunidade embora não tenha acesso as políticas governamentais, apresenta um perfil adequado para implantação de projetos de saneamento ambiental alternativos e de baixo custo. É imprescindível a adoção de soluções de esgotamento de efluentes sanitários e tratamento alternativo da água para a melhoria da qualidade de vida desta comunidade.

An optimization-based decision support system for strategic planning in a process industry: the case of aluminium company in India

We describe how a generic multi-period optimization-based decision support system (DSS) can be used for strategic planning in process industries. The DSS is built on five fundamental elements—materials, facilities, activities, storage areas, and time periods. It requires little direct knowledge of optimization techniques to be used effectively. Results based on real data from an aluminium company in India demonstrate significant potential for improvement in profits. We conclude with a comparison of similar studies in two other process industries.
