International and national research has shown that the use of complementary therapies (often referred to in the scientific literature as either alternative therapies or unconventional therapies) is widespread. However, there is little in the scientific literature about the use of complementary therapies in the treatment regime of people with dementia. Specifically, there have been no published results of investigations into the use of Reiki, a holistic complementary therapy, in the treatment regime of people with dementia. Before proceeding with an in-depth examination into the use of Reiki in the care of people with dementia, a questionnaire containing both closed and open-ended questions was distributed to 162 South Australian High Care Residential Facilities (formerly called Nursing Homes) in 2002. The return rate was 58.0% (n=94) of which 50.0% of the mail out (n=81) was available for analysis. Findings from the questionnaires suggested that a wide range of complementary therapies including aromatherapy, massage, music, behaviour therapy, healing touch, Reiki and Therapeutic Touch (Krieger/Kunz method) were used regularly within South Australian High Care Residential Facilities. Complementary therapies were reportedly used to calm residents, improve behaviour management, enhance the quality of life of residents, promote 1:1 interaction, stimulate the senses, and reduce the need for medication. Due to 15 facilities reporting the use of Reiki, a series of semi-structured interviews with Reiki practitioners caring for people with dementia was conducted in 2004/2005. Interview participants (n=10) included a representative range of people providing care for people with dementia in eight Nursing Homes in Adelaide, South Australia. Data reduction methods included a quasi-statistical counting of key words and repeated re-readings of the transcripts to discover the essences, abstract the meanings and arrange them into themes and sub-themes. The results of the interviews suggested that Reiki is an easy to learn and easy to use holistic complementary therapy which has the potential to enhance the quality of life of the persons with dementia, their family members, and their carers. The interview participants reported improved physical, psychological, mental and emotional well-being as well as enhanced relationships and a reduction in negative behaviours following the use of Reiki. The receipt of the first Jack Loader Scholarship from the Rosemary Foundation for Memory Support Inc. in early 2005 enabled the researcher to transfer to full-time studies from April 2005. Key Words: aged care; alternative therapies; complementary therapies; dementia; early onset dementia; one to one interaction; quality of life; Reiki; therapeutic touch; unconventional therapies.

In the search for companies to distinguish themselves from the mass, so called non-traditional trade marks have become increasingly popular, and in particular colour marks. It is now clear that abstract colour marks can be registered as trade marks, and the number of registered colour marks has increased considerably in recent years. However, it remains a lot more uncertain, mainly due to lack of case law, what the extent of colour marks’ scope of protection is. Are colours actually worth protecting? The purpose of this thesis is to examine the scope of protection of registered abstract colour marks from an EU perspective. Through this examination it will also be established whether colours are worth protecting. The essential function of trade marks is to indicate the origin of products. Signs that are capable of being represented graphically and capable of distinguishing goods and services from one undertaking from those of other undertakings can be registered as trade marks. Colours can fulfil these criteria in certain circumstances, however, colours can practically never have distinctive character per se. Instead, they must have acquired distinctive character through use. Since it is quite difficult to register colour marks, a colour mark proprietor should be prepared to have the validity of his trade mark challenged if he issues proceedings for infringement. There are a few national cases from EU Member States that have concerned infringement of colour marks, and in all of these the plaintiff was successful in claiming infringement. Through the decisions in these cases, general legal principles and statements made in literature, the scope of protection of colour marks has been examined. Infringement of a colour mark occurs in three different situations: where there is likelihood of confusion, where there is double identity and where there is dilution of a trade mark with a reputation. Some of the most important findings are that confusingly similar colours include adjacent shades, but in order to prove likelihood of confusion, the infringing colour must probably be perceived by the public as an indication of origin and other signs that appear together with the colour must probably be taken into account, which limits the scope of protection to some extent. However, since colour marks must almost always have acquired distinctive character through use, consumers are used to perceiving that colour as a trade mark in relation to those types of goods/services, and are therefore more likely to do so also when the colour is used by the third party. Furthermore, there have to be an individual assessment in each case in order to determine whether surrounding signs exclude a likelihood of confusion, where all factors should be considered, including the distinctiveness of the colour mark and how clear and prominent the other signs are. In situations of double identity, the infringing sign does not have to be used as a trade mark, which is advantageous for colour mark owners. Furthermore, identical colours can possibly include other shades if they are so similar that the difference is barely perceptible in a direct comparison. Colour marks can often qualify as trade marks with a reputation, since the assessment of whether trade marks have a reputation is similar to the assessment of whether trade marks have acquired distinctive character through use. Trade marks with a reputation has an extended protection meaning that if a third party uses a sign that is identical or similar to a trade mark with a reputation, and that use without due cause takes unfair advantage of, or is detrimental to, the distinctive character or repute of the trade mark, then that use constitutes infringement. This applies both in relation to identical, similar and dissimilar products, however, it will probably only apply in relation to identical or similar products when it comes to colour marks, due to the extensive use of colours in the market. The extended protection could be relevant in particular in situations where likelihood of confusion cannot be proven, because the public does not perceive the infringing sign as a trade mark or because of surrounding prominent signs. This examination shows that the scope of protection of colour marks is not great, it has some weaknesses. However, it is definitely not worthless either, which clearly shows in the fact that the plaintiffs were successful in claiming infringement in all of the infringement cases. By registering a colour as a trade mark, a company can to some extent stop others from using the same or similar colour, and it will also most likely have a discouraging effect. However, some carefulness should still be applied in relation to colour marks, since this is still a very new phenomenon and additional case law can take another direction. But considering how the situation looks today, colours are worth protecting as trade marks.

CeCu_2Si_2 was the first heavy-fermion compound showing signatures of bulk superconductivity (T_c = 0.5 K). Further observations have put in evidence the correlations between superconductivity, magnetic order, Kondo physics, and quantum critical phenomena. In spite of the interest generated, a systematic study of such correlations was hampered by strong sample dependences. Fortunately, the inherent complexity associated to the stoichiometric composition has been recently understood. The availability of single-crystals with well-defined properties has thus reignited the interest in CeCu_2Si_2 as a window to novel phenomena, such as unconventional superconductivity. The present work summarizes the results of my doctoral research. It exemplifies the importance not only of high-quality materials, but also of suitable experimental techniques. A first step in this project involved the design of angle-dependent techniques in the milli-kelvin range, namely: electrical resistivity and thermal conductivity. It comprised the development of a rotational stage, the construction of sample holders, and the implementation of controlling and measuring components. In the second part of the project, electrical- and thermal-transport measurements on CeCu_2Si_2 were performed. Power-law behavior below T_c in the thermal conductivity suggests the presence of lines of nodes in the gap function. Also, the non-vanishing extrapolated residual terms (k_00/T ) support the presence of a residual density of states. The nodes are broadened by potential scattering, which appears to be significant in CeCu_2Si_2. The scattering hinders the determination of the symmetry of the order parameter and might be responsible for the observed isotropic angle dependence of the thermal conductivity. In contrast, angle-dependent measurements of the upper critical field exhibit a four-folded behavior, which also points towards the presence of nodes. By comparing with a weak-coupling model including the effects of Pauli limiting and anisotropic Fermi velocity, the results point towards a d_xy-wave symmetry of the order parameter. Such results represent the first angle-dependent measurements supporting a d-wave symmetry in CeCu_2Si_2.

Reserves estimation in an unconventional-reservoir setting is a daunting task because of geologic uncertainty and complex flow patterns evolving in a long-stimulated horizontal well, among other variables. To tackle this complex problem, we present a reserves-evaluation workflow that couples the traditional decline-curve analysis with a probabilistic forecasting frame. The stretched-exponential production decline model (SEPD) underpins the production behavior. Our recovery appraisal workflow has two different applications: forecasting probabilistic future performance of wells that have production history; and forecasting production from new wells without production data. For the new field case, numerical model runs are made in accord with the statistical design of experiments for a range of design variables pertinent to the field of interest. In contrast, for the producing wells the early-time data often need adjustments owing to restimulation, installation of artificial-lift, etc. to focus on the decline trend. Thereafter, production data of either new or existing wells are grouped in accord with initial rates to obtain common SEPD parameters for similar wells. After determining the distribution of model parameters using well grouping, the methodology establishes a probabilistic forecast for individual wells. We present a probabilistic performance forecasting methodology in unconventional reservoirs for wells with and without production history. Unlike other probabilistic forecasting tools, grouping wells with similar production character allows estimation of self-consistent SEPD parameters and alleviates the burden of having to define uncertainties associated with reservoir and well-completion parameters.

Various models featuring horizontal wells with multiple induced fractures have been proposed to characterize flow behavior over time in tight gas and shale gas systems. Currently, there is little consensus regarding the effects of non-ideal fracture geometries and coupled primary-secondary fracture interactions on reservoir performance in these unconventional gas reservoirs. This thesis provides a grid construction tool to generate high-resolution unstructured meshes using Voronoi grids, which provides the flexibility required to accurately represent complex geologic domains and fractures in three dimensions. Using these Voronoi grids, the interaction between propped hydraulic fractures and secondary "stress-release" fractures were evaluated. Additionally, various primary fracture configurations were examined, where the fractures may be non-planar or non-orthogonal. For this study, a numerical model was developed to assess the potential performance of tight gas and shale gas reservoirs. These simulations utilized up to a half-million grid-blocks and consider a period of up to 3,000 years in some cases. The aim is to provide very high-definition reference numerical solutions that will exhibit virtually all flow regimes we can expect in these unconventional gas reservoirs. The simulation results are analyzed to identify production signatures and flow regimes using diagnostic plots, and these interpretations are confirmed using pressure maps where useful. The coupled primary-secondary fracture systems with the largest fracture surface areas are shown to give the highest production in the traditional "linear flow" regime (which occurs for very high conductivity vertical fracture cases). The non-ideal hydraulic fracture geometries are shown to yield progressively lower production as the angularity of these fractures increases. Hence, to design optimum fracture completions, we should endeavor to keep the fractures as orthogonal to the horizontal well as possible. This work expands the current understanding of flow behavior in fractured tight-gas and shale-gas systems and may be used to optimize fracture and completion design, to validate analytical models and to facilitate more accurate reserves estimation.

In this thesis, an extended periodic Anderson model with an additional local Coulomb repulsion U f c between localized f electrons and conduction electrons is investigated by use of the projector-based renormalization method (PRM). First, it is shown that the model in one dimension shows a valence transition, which becomes sharper, when the energy of the f level approaches the Fermi level. The transition becomes also enhanced, when the hybridization V between the localized and conduction electrons decreases, for the case that the total number of electrons is fixed. In the two-dimensional case, one finds a similar valence transition behavior. However, in the valence transition regime also a superconducting phase may occur. To investigate this phase, we start from an Hamiltonian which includes small gauge symmetry breaking fields. We derive renormalization equations, from which the superconducting pairing functions are self-consistently determined. Our analytical and numerical results show that d- wave superconductivity becomes dominant in the valence transition regime. This confirms the suggestion by Miyake that valence fluctuations may lead to superconductivity in the Ce based heavy-fermion systems under high pressure. / In dieser Arbeit wird mit Hilfe der projektiven Renormierungsmethode (PRM) ein erweitertes periodische Anderson Modell untersucht, das zusätzlich eine Coulomb-Abstoßung zwischen den lokalisierten f-Elektronen und den Leitungselektronen enthält. In einer Dimension zeigt das Modell einen Valenzübergang, wenn sich die Energie des f-Niveaus der Fermienergie nähert. Der Übergang wird ebenfalls schärfer, wenn bei festgehaltener Gesamtelektronenzahl die Hybridisierung V zwischen den lokalisierten und den Leitungselekronen abnimmt. In zwei Dimensionen findet man ein ähnliches Valenzübergangsverhalten. Allerdings kann zusätzlich eine supraleitende Phase im Valenzübergangsgebiet auftreten. Um die supraleitende Phase zu untersuchen, betrachten wir einen Hamiltonoperator mit kleinen zusätzlichen Feldern, die die Eichsymmetrie brechen. Wir leiten Renormierungsgleichungen her, aus denen sich die supraleitenden Paarfunktionen selbstkonsistent bestimmen lassen. Unsere analytischen und numerischen Resultate zeigen, dass im Valenzübergangsgebiet d-Wellen-Supraleitung dominiert. Dies bestätigt eine Vermutung von Miyake, dass Valenzfluktuationen in Ce-basierten Schwerfermionensystemen bei hohen Drücken zur Supraleitung führen können.

Over 18 billion barrels of waste fluids are generated annually from oil and gas production in the United States. As a large amount of water is used for oilfield operations, treating and reusing produced water can cut the consumption of fresh water in well sites. This research has helped to develop a membrane process train for a mobile produced water treatment unit for treating oilfield produced brine for reuse. To design the process train, over 30 sets of combination tests at pilot laboratory scale were performed using pretreatment, microfiltration and nanofiltration processes. Membrane performance was selected based on high flux separation efficiency, high tolerance for solids and fluid treatments. Over 95 % solids rejection and greater than 80 % oil removal efficiency were obtained in all these tests. Process train (pre-treatment and membrane) performance was monitored by chemical analysis of permeate and models fitting experimental data for the process. From the results, hydrocarbon rejection was analyzed; total organic carbon rejection was 47.9 %, total carbon content averaged 37.3 % rejection and total inorganic carbon rejection was at 3.66 %. BTEX removal efficiency ranged from 0.98 % to 52.7 % with the progressive pretreatment methods of using cartridge filters. The nanofiltration membrane showed significant reduction in total dissolved solids and in both anionic and cationic species. The process train is seen to follow a sequence of treatment from cartridge and oil removal filter treatment to microfiltration treatment to ultrafiltration, followed by nanofiltration for the purpose of this research. Further research still needs to be done on to determine the kind of analytical test which will give real time feedback on effectiveness of filters. In summary, the process train developed by TAMU-GPRI possesses distinct advantages in treating oilfield produced brine using membrane technology. These advantages include high quality of permeate, reduced sludge and the possibility of total recycle water systems. The small space requirement, moderate capital costs and ease of operation associated with the use of the mobile unit membrane technology also makes it a very competitive alternative to conventional technologies.
