Space in Anita Desai¡¦s Clear Light of DayLin, Ya-chen 10 August 2009 (has links)
This thesis examines the spatial representations of India as respectively a nation-state, a colony, and a member of the third-world countries in modern history in Anita Desai¡¦s Clear Light of Day. According to Henri Lefebvre, space is simultaneously a part in the production and a product. An abstract space has a goal in homogeneity; however, the realization of spatial plan is usually interfered by different ideologies. The flow of the entangling ideologies embedded in the novel is embodied in the family house, the modern city, and the imagination of India as a tourist attraction. Chapter One applies Cathy Caruth¡¦s traumatic theory to demonstrate the family house as a symbol of the dominating Hindu nationalist discourse. The separation of the Das family is taken as an allegorical representation of the Partition. Recollecting the traumatic past, the Das encounters repetitively the crisis of identity caused by the separation and the diversity of discourses. The Hindu nationalist discourse has occupied the family house as the position of articulation. The authoritative discourse promotes the establishment of India as a nation-state through excluding the elements of difference. In addition, the colonial design of establishing New Delhi as a modernist capital reflects the British government¡¦s plan to assimilate Indian colony. Chapter Two applies Michel Foucault¡¦s theories of power and space to analyze first British governmentality in making the new capital a homogeneous space and, secondly, the potential resistance generated from the variety of local cultures. Eventually, New Delhi exhibits itself a synthesis of the modern and the tradition, of the western and the local. Chapter Three explores Indian intellectuals¡¦ dilemma of cultural identity in diaspora. As Rey Chow indicates, the third-world intellectuals articulate for the marginalized; however, the minor of the minor has still been left in the dark. While the diplomat Bakul decides to tell the foreigners only the glory of India exclusive of the socio-political calamities, the local reality is estimated as dispensable for the first-world imagination. Furthermore, the Eurocentric grand narrative embedded in the third-world studies locates the diasporic¡¦s recognition of India oscillating between homeland and tourist attraction.

Organic chlorine in soilwater : Influence of Clear-cuttning and NitrogenFredriksson, Maria January 2007 (has links)
<p>Chlorine is one of most common element on earth and it is essential in every living organism, but can also cause problems in the environment. Chlorine can exist both as inorganic (Clin) and organically bound (Clorg). Earlier was the common opinion that Clorg only occurs from anthropogenic sources, but the last years, research has shown that chlorine is a part of the biogeochemical cycle and Clorg also can have natural sources. Many chlorinated substances are poisonous, so the fact that they have a natural source created attention. Fertilizations with nitrogen in forest areas have shown unexpected consequences, such as an increase leakage of nitrogen to ground and surface water. Clear-cutting is a disturbance on the ecosystem and the environment is sensitive for disturbances. Because of the fact that both chlorine and fertilization can be environmental problems and that clear-cutting is a big disturbance in the nature, this study will investigate if there are changes of organic chlorine (Clorg) in soil water after clear-cutting and if fertilization with nitrogen has any influence on the concentration of Clorg. This study was made in a forest area in Värmland, Sweden (Hagfors). Chemical analyses were made in the laboratory though measuring AOX (absorbable organic halogens). The result of this study showed that clear-cutting probably has some effect on the Clorg concentration and that nitrogen doesn’t have any influence.</p>

Plain, but not Simple: Plain Language Research with Readers, Writers, and TextsGarwood, Kimberley Christine 29 August 2014 (has links)
Plain language is defined in a variety of ways, but is generally understood to refer to language and design strategies that make texts easier for target audiences to understand and use. Research has helped demonstrate that plain language strategies work, not only to improve reader comprehension, but also to save individuals and organizations time and money. Most plain language research focuses on the outcomes of plain language texts; however, there are a variety of complex processes that happen behind the scenes as these texts are produced. To better understand the complexity of plain language work and the challenges of producing these texts, this dissertation studies plain language using rhetorical and sociolinguistic theories. This framework allows us to see how plain language produces meaning within complex social and cultural contexts. Using the rhetorical triangle as an organizing framework, this dissertation proposes three models of research for studying plain language, each emphasizing a different part of the triangle: readers, writers, and texts.

A new approach to ensure successful implementation and sustainable DSM in RSA mines / Daniël Francois le RouxLe Roux, Daniël Francois January 2005 (has links)
In this study a new tool was developed that made new approaches possible for the successful
implementation of Demand Side Management (DSM) projects. The new approaches are
incorporated into a generic tool that makes it possible for Energy Services Companies (ESCos) to undertake DSM projects that were previously not possible with currently available technology.
Through these new approaches, maximum results can be obtained on a sustainable basis on the
clear water pumping systems of South African mines.
The author was responsible and participated in four different investigations and implementations of
DSM projects. These were grouped into three case studies. Each of these studies required different
new innovations.
The innovations described in this thesis include the adaptation of the Real-time Energy
Management System (REMS) that was developed and marketed by HVAC International, to mines
with intricate pumping systems, mines without any instrumentation and control infrastructure, as
well as to mines that make use of a Three Pipe Water Pumping System.
The tool developed and applied in these projects was part of Eskom's DSM programme. In this
programme, large electricity clients who wish to shift electrical load out of peak periods, are
assisted by having the total costs of such projects funded by Eskom. The fact that the clients will
most likely enjoy substantial electricity cost savings, (by not having to pay the high peak prices), is
a major attraction of this programme. Nevertheless, the programme is not moving as fast as it
should.
The National Energy Regulator (NER) has set an annual target of 153 MW load to be shifted since
2003. By the end of 2005, the accumulated target load to be shifted will be 459 MW. However,
Eskom has indicated that an accumulated total of only 181 MW load will have been shifted by the
end of 2005. This means that the Eskom DSM programme has actually only achieved 39% of its
target.
The innovations described in this thesis will help ESCos to address this shortfall more effectively / Thesis (Ph.D. (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2006

Researching the long-term impact of load management projects on South African mines / Nicolaas Cornelius Jacobus Marthinus de KockDe Kock, Nicolaas Cornelius Jacobus Marthinus January 2006 (has links)
Eskom is currently facing an energy crisis due to the limited operational electricity generating
capacity in South Africa. The historically low electricity price, the rapid growth in economy
and the energy intensive nature of South African industries are the most common reasons for
the peak supply problem.
Various supply and demand technologies have been identified to address this energy crisis.
Due to the lengthy process of building new peaking load power stations, Eskom has initiated
the Demand-side Management (DSM) programme as a solution to the short-term supply
problem.
The National Energy Regulator (NER) has set targets to Eskom DSM to reduce the evening
peak demand by 153 MW per annum and 4 255 MW over a 20-year planning horizon. Due to
the energy intensive nature of the mining industry, it has been targeted for DSM savings. To
date there have been a number of DSM projects implemented on the clear-water pumping
systems of various mines, with a large potential for DSM savings identified on future projects
still unrealised.
The generation benefit of DSM load-shifting projects is twofold; firstly Eskom's evening load
capacity increases due to the reduction in demand during these periods and secondly, the
mine receives electricity cost savings due to load management practices. Because Eskom
DSM is dependent on the client consumer to accept and roll-out the DSM programme, client
satisfaction is of paramount importance. Due to the fact that load-shifting efforts require from
the mine to change their normal operating schedules, there is uncertainty on the impact and
knock-on effects of DSM projects on a mine.
Therefore, the purpose of this study is to investigate and thereafter quantify the overall
impact of DSM load-shifting on the clear-water pumping system of South African mines. A
generic model was developed by performing case studies on existing DSM projects. This
model was then applied to future DSM projects to validate the findings made throughout the
research study.
The case studies performed on existing DSM projects, as well as the results obtained when
modelling the overall impact of DSM on future mines, proofs that DSM definitely benefits a
mine. The total annual cost saving on the four future DSM projects is predicted to be in the
order of R 7.64 million instead of the R 4.27 million when considering only the electricity cost
savings to the mine. / Thesis (M.Ing. (Electrical Engineering))--North-West University, Potchefstroom Campus, 2007.

Comparison between automated and manual DSM pumping projects / R.P. RichterRichter, Rudolph Petrus January 2008 (has links)
The purpose of this dissertation is to identify the best alternative method of load shifting on clear water pumping systems in the mining industry. This can be done through a comparison analysis between manual and automated Demand Side Management (DSM) projects. The study holds benefits for Eskom and any client wishing to participate in the program. Eskom, by choosing the best method, will ensure sustainable load shifting while the client benefits financially through lower electricity costs.
In order to perform this study, research was conducted on the requirements for additional electricity supply in South Africa. Research showed that there is an urgent requirement for additional electricity supply to ensure continued economical growth. DSM was identified as one of the most favourable methods that could be implemented to address the problem. A reason for this is DSM projects are economically viable and can be implemented in a relatively short time. The initiative would also decrease the need for increasing electrical generation capacity.
During the research study important information regarding the computation process for load shifting and cost saving performance was gathered. Research was also conducted on the effect of DSM on labour and maintenance cost reduction, as well as economical engineering methods that can be used for alternative selection. The difference in performance between automated and manual systems was compared. The
results showed that a 40% improvement of automated systems over manual systems were attainable and sustainable. This will realise a total saving of approximately 45% in electricity costs for the client. Savings in labour and maintenance costs are shown to be achievable through the automation of pumping systems. These saving results were used in the Engineering Economic alternative selection methods where applicable. Economic calculations confirmed that automated projects are the most viable control method.
From the comparison study, it is shown that automated controlled systems are more
advantageous than manually controlled systems. It will therefore be in the best interest of the client to automate a manually controlled pumping system, as it will result in additional load shifting and cost saving. / Thesis (M.Ing.

The Short-term Impacts of Aspen Clear-cutting on Upland Groundwater Recharge / Clear-cutting Impacts on Groundwater RechargeHairabedian, Melissa Manuella 06 1900 (has links)
The impacts of aspen clear-cutting on upland groundwater recharge are presented based on two years (2007-2008) of the five year (2005-2009) HEAD2 NSERC-CRD paired-catchment experiment. Research was conducted at the Utikuma Region Study Area (URSA), 370 km north of Edmonton, Alberta, Canada, in the Boreal Plain ecozone. Results show greater soil water content in the root zone and potential for recharge into the deeper unsaturated zone during the first year of regeneration. Sites with shallow water table levels (<600 cm) increased more than sites under uncut conditions. Sites with deeper water table levels (>600 cm) responded minimally, if at all, to spring-melt and summer storms suggesting that water exchanges with the atmosphere occurred to and from the unsaturated zone only during the first-year regeneration. Upland groundwater gradients to adjacent pond-peatland complexes persisted at least ten times longer under clear-cut than under uncut conditions. Water table trends recovered to uncut conditions by the second year of regeneration. / Ecology
