The purpose of this article (as part of a larger study) is to develop and apply a methodology for analysing and assessing the competitive position of the Fantastic Services Australia (FSA) brand in the surveyed country (and the major regional domestic services markets––Melbourne and Sydney). Based on scientifically grounded analysis, theoretical ideas and exploration of FSA markets, the paper highlights some marketing prospects for the company and draws conclusions and guidelines for building an appropriate positioning strategy for the respective regions and types of services (end of lease cleaning, carpet cleaning and one-off cleaning). FSA is one of the largest market players, both in terms of scale and network of franchisees, and this coupled with the intensive rivalry it faces further elucidates the need for carefully calibrated brand positioning to maintain competitive edge.
Keywords: Brand positioning, positioning strategy, domestic services.

This paper analyzes how a key conflict in Australia's pulp and paper industry became generalized to other sites through environmental action, government regulation, and industry initiative. From 1987–91, Australians debated construction of a new, world-class, export-oriented pulp mill in Tasmania. Rural residents, fishermen, and environmentalists, allied with the Australian Labor Party, succeeded in scuttling the project. Subsequently, the national government launched a major research program, state governments tightened regulations, and industry reduced elemental chlorine use. Any new mills constructed in Australia today would be among the cleanest in the world. This paper is part of a larger, comparative study of technological innovation in the pulp and paper industries of Australia, Indonesia, Malaysia, and Thailand. The author interviewed industry officials, government regulators, research scientists, and environmentalists; visited pulp and paper mills; attended technical conferences; and conducted archival work in these countries during a 12-month period.

Full textAbstract:
Abstract The paper provides a review of fractional technologies developed by the authors, allowing to divide the grain heap coming from combines into 3 fractions: seed, fodder and unused waste. They are based on the use of two-aspiration air-sieve grain cleaning machines. The authors have developed a line of grain cleaners OZF-50/25/10 and OZF-80/40/20. Their productivity in terms of preliminary cleaning is 50 and 80 t/h, primary cleaning productivity is 25 and 40 t/h and secondary cleaning productivity is 10 and 20 t/h, respectively. The machines use an improved two-aspiration system with the ability to independently adjust the speed of air flows in the channels (patent No. 2298441), a new design of a sieve mill with a two-tier arrangement of sieves and setting in each tier sequentially two (at OZF-50/25/10) and three (on OZF-80/40/20) sieves. The mills implement a new sieve arrangement scheme (RF patent No. 43798), as well as original devices for a ball sieve cleaner and a pneumatic separation channel for the second aspiration. These devices make it possible to obtain the required quality of sieve cleaning and to isolate biologically defective grain in the pneumatic separation channel of the second aspiration. The separator for secondary cleaning of seeds SVS-30 is designed for the preparation of seeds of grain, spike, leguminous, industrial and oil crops when implementing fractional technology during post-harvest processing. Like all machines for secondary cleaning of seeds, the pneumatic system of the separator has two pneumatic separation channels for pre-screening and post-screen cleaning. A distinctive feature of the pneumatic system of the SV-30 separator is the consistent use of the same air flow in both aspirations. Fractional technology for processing grain heaps, implemented on an air-sieve separator, will increase the cleaning performance by 1.5…1.8 times with a minimum amount of mechanical stress on the seeds.

Full textAbstract:
Abstract A large-scale study on bisphenol A (BPA) contamination in Canadian municipal and industrial wastewater and sludge has been completed. A total of about 200 samples were collected, including those from 31 sewage treatment plants and 15 pulp and paper mills across Canada, as well as 13 industrial facilities in the Toronto area. The samples were extracted by previously developed solid-phase and supercritical carbon dioxide extraction procedures and were analyzed by gas chromatography-mass spectrometry. BPA contamination was detected in all of the 72 sewage samples, with concentrations ranging from 0.080 to 4.98 µg/L (median 0.329 µg/L) for the influent, and from 0.010 to 1.08 µg/L (median 0.136 µg/L) for the effluent. Of the 36 influent/effluent sample pairs studied, BPA in the influent is removed by the sewage treatment process at a median reduction rate of 68%. Levels of BPA accumulation in sewage sludge, for the 50 samples tested, ranged from 0.033 to 36.7 µg/g, on a dry weight basis. A wide range of BPA concentrations, from 0.23 to 149.2 µg/L, were observed for the wastewater collected from selected industrial facilities in the Toronto area. The more contaminated samples came from the sectors of chemicals and chemical products, commercial dry cleaning, as well as packaging and paper products. Based on these data, on-site releases of BPA by industrial facilities seem to be much more widespread than the National Pollutant Release Inventory (NPRI) database has suggested. While relatively high levels of BPA were found in some of the primary treated effluent collected from the deinking mills, BPA concentrations in the secondary treated effluent of all pulp and paper mills were low, with a range from < 0.005 to 0.0406 µg/L. Except for the samples derived from a few deinking mills, BPA contaminication in pulp and paper mill sludge was either low or undetected.

Urbanization increases the variety and amount of pollutants transported to receiving waters. Sediment from development and new construction; oil, grease, and toxic chemicals from automobiles; nutrients and pesticides from turf management and gardening; viruses and bacteria from failing septic systems; road salts; and heavy metals are examples of pollutants generated in urban areas. Sediments and solids constitute the largest volume of pollutant loads to receiving waters in urban areas. When runoff enters storm drains, it carries many of these pollutants with it. In older cities, this polluted runoff is often released directly into open waterways without any treatment. Increased pollutant loads can harm fish and wildlife populations, kill native vegetation, foul drinking water supplies, and make recreational areas unsafe. The objective of the study, performed by University of Pavia (Italy), University of Brescia (Italy) and GreenTechTexas International (US), reported herein is to evaluate the use of an innovative stormwater technology (EcoDräin(tm)) to reduce pollution due to urban runoff in existing urban areas. The paper describes the methodology and the results achieved with tests conducted in laboratory in Pavia University in Italy and in two pilot areas in Italy and in Australia to investigate the EcoDrain's effectiveness for oil and heavy metals retention and sediment trapping. In the tests performed in a marina near Sidney in Australia a reduction has been achieved in oil and grease concentration higher than 95% and a reduction in metal concentration (particularly Copper, Lead and Zinc) close to 98%. The paper also describes the methodology of the analysis on the absorbing material after its use and the consequent determination of the most efficient and environmentally safe way to dispose of consummated absorbent.

Full textAbstract:
The overall objective of the work reported in this paper is to minimize the cost of power generation in thermal power stations utilizing pulverized coal combustion processes for steam generation. The strategy of achieving this objective is based on an “on-condition maintenance” philosophy and vibration based diagnostic signature analysis techniques. The coal pulverizers reported on here are 783 RP (roll pressure) and 823 RP combustion engineering (CE) bowl-roller coal pulverizers (bowl mills) installed at the State Energy Commission of Western Australia (SECWA) power stations. This paper reviews the design philosophy, operational principles, and system dynamics and establishes the procedures for identifying the potential malfunction of bowl mills and their associated components. The influence of operating parameters, such as coal flow, primary air flow, and operating temperature, on mill vibration are investigated. The effects of journal spring force variation, such as magnitude, uneven spring force, and broken springs, are also studied. Special attention is also given to the diagnosis of the top radial bearing problem due to its remoteness from the bowl mill external structure. A spectral recovery technique utilizing the inverse frequency response function was developed for trend analysis and diagnostic purposes.

In order to solve the problems of aluminum package cleaning a kind of method of milling process for internal surface is proposed. Using three standard cutters which move as planets complete the milling processing for inner cylinder and bottom surface. This method makes the cutters forced reasonably and cutting efficiency is promoted. The adjusting device which is arranged on bigger mills makes the processing size to be changed so the applicability of this cutting method is improved greatly. After research the calculating method of cutting amounts and cutting force are established. The cutting capability of the new method is also analyzed in the paper. By the way the relation curve of cutting amounts and cutting force with cutter rotation rate are given. The achievements above will provide a theoretical basis for the application of this method.显示对应的拉丁字符的拼音

Full textAbstract:
The paper deals with the effects of the structural state modification of the main pulverulent component used for the alloying of metallic products made of steels, cast iron or nonferrous alloys, on the layers kinetics formation. The aliting process is most often done in a powdery mixtures, composed of three components: the active component providing aluminum, a neutral one with the role of dispersing the others, also having the role of blocking the sintering tendency and a halide as an activator, by cleaning the metal surfaces to be saturated. The aim of the paper is to present the ways to ensure the kinetics of the aliting layer formation, while reducing the heat treatment temperature. These could be accomplished by replacing the aluminum or ferroaluminum powder with equimassic amounts mixture of thermitic powders, consisting of ferrous oxides and aluminum powders, mechanically alloyed in high energy ball mills. Thus, it is possible to produce the aluminothermic reduction reaction in the component obtained by mechanical alloying at the same time generating notable thermal effects.

Understanding the flows of people moving through the built environment is a vital source of information for the planners and policy makers who shape our cities. Smart phone applications enable people to trace themselves through the city and these data can potentially be then aggregated and visualised to show hot spots and trajectories of macro urban movement. In this paper our aim is to develop procedures for cleaning, aggregating and visualising human movement data and translating this into policy relevant information. In conducting this research we explore using bicycle data collected from a smart phone application known as RiderLog. We focus on the RiderLog application initially in the context of Sydney, Australia and discuss the procedures and challenges in processing and cleaning this data before any analysis can be made. We then present some preliminary map results using the CartoDB online mapping platform where data are aggregated and visualised to show hot spots and trajectories of macro urban movement. We conclude the paper by highlighting some of the key challenges in working with such data and outline some next steps in processing the data and conducting higher volume and more extensive analysis.

Full textAbstract:
13 uranium mines operated in the South Alligator Valley of Australia’s Northern Territory between 1953 and 1963. At the end of operations the mines, and associated infrastructure, were simply abandoned. As this activity preceded environmental legislation by about 15 years there was neither any obligation, nor attempt, at remediation. In the 1980s it was decided that the whole area should become an extension of the adjacent World Heritage, Kakadu National Park. As a result the Commonwealth Government made an inventory of the abandoned mines and associated facilities in 1986. This established the size and scope of the liability and formed the framework for a possible future remediation project. The initial program for the reduction of physical and radiological hazards at each of the identified sites was formulated in 1989 and the works took place from 1990 to 1992. But even at this time, as throughout much of the valley’s history, little attention was being paid to the long term aspirations of traditional land owners. The traditional Aboriginal owners, the Gunlom Land Trust, were granted freehold Native Title to the area in 1996. They immediately leased the land back to the Commonwealth Government so it would remain a part of Kakadu National Park, but under joint management. One condition of the lease required that all evidence of former mining activity be remediated by 2015. The consultation, and subsequent planning processes, for a final remediation program began in 1997. A plan was agreed in 2003 and, after funding was granted in 2005, works implementation commenced in 2007. An earlier paper described the planning and consultation stages, experience involving the cleaning up of remant uranium mill tailings and other mining residues; and the successful implementation of the initial remediation works. This paper deals with the final planning and design processes to complete the remediation programme, which is due to occur in 2009. The issues of final containment design and long term stewardship are addressed in the paper as well as some comments on lessons learned through the life of the project.

Full textAbstract:
In March 2008, Keppel Seghers started the engineering, supply, construction and commissioning of a Combined Heat and Power (CHP) Waste-to-Energy (WtE) plant in A˚motfors (Sweden). When completed in 2010 the plant will process close to 74,000 tons per year of household waste (average LHV = 10.5 MJ/kg) and limited quantities of (demolition) wood resulting in a yearly production of about 108,700 MWh of steam, 12,100 MWh of heat and 13,400 MWh of electricity. Herewith, the A˚motfors WtE-CHP is sized to meet the joined energy needs of the local paper production, neighboring industries and buildings at an overall net plant efficiency of almost 65%. The WtE-CHP will offer state-of-the-art combustion and energy recovering technology, featuring Keppel Seghers’ proprietary Air-Cooled Grate, SIGMA combustion control and integrated boiler. Waste is fed into the combustion line with an automatic crane system. To surpass the stringent EU emission requirements, a semi-dry flue gas cleaning system equipped with Keppel Seghers’ Rotary Atomizer was selected as economic type of process for purifying the combustion gas from the given waste mixture. Furthermore a low NOx-emission of 135 mg/Nm3 (11%O2, dry) as imposed by Swedish law is achieved by SNCR. The plant engineering is described with a focus on the overall energy recovery. As stable steam supply to the paper mill and the district heating system needs to be assured under all conditions the design includes for supporting process measures such as combustion air preheating, steam accumulation, turbine bypassing, buffering of the main condenser and back-up energy supply from an auxiliary fuel boiler. Additionally, external conditions can trigger distinct plant operation modes. A selected number of them are elaborated featuring the WtE-plant’s capability to conciliate a strong fluctuating steam demand with the typical intrinsic inertia of a waste-fired boiler. With prices for fossil fuels increasing over the years, the cost for generating process steam and heat has become dominant and for paper mills even makes the overall difference in viability. As will be documented in this paper, the decision to build the A˚motfors WtE-CHP was taken by Nordic Paper after a quest for significant cost-cutting in the production of process energy. Moreover, the use of industrial and household waste as fuel brings along the advantage of becoming largely independent from evolutions on the international oil and gas markets. By opening up the possibility for a long-term secured local (waste) fuel supply at fixed rates, WtE-technology offers a reliable alternative to maintain locally based industrial production sites. The Nordic Paper mills in A˚motfors are therefore now the first in Sweden to include a waste-fired CHP on a paper production site.

"Co-Combustion of Pulp- and Paper Sludge With Wood: Emissions of Nitrogen, Sulphur and Chlorine Compounds." In 17th International Conference on Fluidized Bed Combustion. ASMEDC, 2003. http://dx.doi.org/10.1115/fbc2003-097.
Full textAbstract:
Sludge from wastewater treatment plants in five Swedish pulp and paper mills has been burned together with wood in a circulating fluidised bed (CFB) boiler. The sludge was either mechanically dewatered or pre-dried. The mechanically dewatered sludge had to be fed with a pump, but the pre-dried sludge could be fed by the fuel feed system normally used for coal, wood chips or wood pellets. In parallel to the combustion tests in the CFB boiler the sludges were also investigated as single fuels in a small laboratory FB. The Swedish pulp and paper industry produces three major fractions of sludge: pure fibre sludge, sludge produced by employing a precipitation species like ironaluminiumsulphate, and finally, sludge subjected to biological cleaning. The way of production of the sludge influences its content of, for example, nitrogen, sulphur and chlorine, but the composition of the sludge is also influenced by the pulp and paper process. The present measurements show that the concentrations of nitrogen, sulphur and chlorine in the sludge have a great impact on the corresponding gaseous emissions from combustion. Actions to prevent these emissions could be necessary, depending on the origin of the sludge and treatment process used. In the present project all sludges were burned with wood-pellets as the main fuel under identical operating conditions, typical for a CFB boiler. Wood pellets were chosen as a well defined, low-polluting fuel that makes comparison of emissions from the sludges clear. Co-combustion with wood-pellets has the advantage of enabling operation also with wet sludges that cannot be used as single fuels without pre-drying. No actions were taken to improve sulphur and chlorine retention, by for example adding limestone. From a combustion point of view the co-combustion works well with low levels of carbon monoxide present in the flue gas and no light hydrocarbons.
