Ternary Phase Diagram Determinations Concerning Potassium Electrolyte Influence On Aqueous Solutions Of Dioxane Or Tetrahydrofuran

For the graphical representation of the mutual, partial solubilities of a·ternary system, a diagram is generally employed which is based upon the equilateral triangle, whose properties are especially felicitous for this-purpose. In this study, the phase diagrams for the following systems were determined: potassium acetate-water-dioxane, potassium acetate-water-tetrahydrofuran, potassium benzoate-water-dioxane, potassium benzoate-watertetrahydrofuran, potassium chloride-water-tetrahydrofuran, and potassium hydroxide-water-dioxane. The systems, potassium acetate-water-dioxane and potassium hydroxidewater-dioxane, were investigated at 25° and 85°. This study indicates that they are, to a slight degree, temperature dependent. When these systems were plotted on a mole-percentage basis, it was found that both potassium compounds have about the same phase separating ability per molecule. The solubility curves of potassiwn benzoate in water-dioxane and in water-tetrahydrofuran solutions were determined through the employment of a modified Schreinemakers wet residue method. It was established that this salt cannot stratify aqueous solutions of either dioxane or tetrahycirofuran into two liquid phases. The phase diagram of potassium chloride-water-tetrahydrofuran was the only diagram, of those determined in this study, in which an invariant point was discovered. The reason such an invariant point exists is related to the fact that potassium chloride does not produce a salting-out effect through the full percentage composition range of this ternary mixture. Other investigators have found that the greater the water solubility of a given alkali-metal salt, the greater is its salting-out effect. The water solubility of the salts investigated in this study are compared as follows: potassium acetate \u3e\u3e potassium chloride \u3e\u3e potassium benzoate. Potassium acetate was found to have the greatest capacity to stratify aqueous solutions of tetrahydrofuran and aqueous solutions of dioxane, potassium chloride has a lesser capacity to bring this about, and potassium benzoate cannot stratify these solutions. Within the limits of precision available in this work, none of the electrolytes investigated was found to be soluble in either of the organic solvents employed

Jane Eyre's Arrival at Thornfield Hall: Illustration of Jane Eyre’ arrival at Thornfield Hall

The illustration was awarded first prize in the illustration section of the Brontë Society creative competition. The print submitted for the Brontë creative competition investigated and examined the use of hand drawn elements in a predominantly photographic printing process and how this might be developed and disseminated to the design student cohort through my teaching using the photogravure method of creating mark-making. The work has been viewed at local, national and international levels by those interested in the works of the Bronte’s and the research could potentially give a greater understanding of the history and literature of the Bronte’s to general art enthusiasts and a wider public audience.

The design and evaluation of novel technologies for the self monitoring and management of Parkinson's symptoms

PhD ThesisThis thesis explores how digital technologies might better support people with Parkinson’s (PwP) to take control of their condition, by engaging in self monitoring and management practices. The specific focus of this thesis is around issues managed by Speech and Language Therapists (SLTs) (namely drooling and speech and voice changes). Three case studies were used to explore the ways that different technologies might be configured to aid the self monitoring and management of these speech and drooling symptoms. The first case study describes an evaluation of PDCue, a wrist worn device to assist the self management of drooling through the use of a temporal cueing method, to increase swallowing frequency. This study showed evidence that drooling can be behaviourally self managed through cueing—like other symptoms of Parkinson’s such as gait freezing—and proved a viable first step towards re-considering the use of additional medications as a first option for drooling treatment. However, whilst this study proved successful in understanding the ways in which a simple, temporal cueing technique might support drooling management, it opened up questions around the ways in which PwP might use technology to actively think about and understand their condition through self monitoring, and use this information to support self management practices further. In response, the second case study describes the design and evaluation of LApp, an application to support both the self monitoring and management of vocal loudness issues through the use of an insitu cueing approach. The Google Glass was chosen as the platform to run the cueing method on, due to its technical capabilities as a multi-sensor, wearable platform, to analyse a constant stream of audio and provide real time visual prompts to support the wearer in increasing their volume at times when it is needed in conversation. This study highlighted how participants saw value in LApp in supporting their loudness issues, but also noted a desire for participants to understand more about their speech and the SLT strategies that they were required to do in order to improve it. The third case study drew upon this desire for increased understanding by developing and evaluating Speeching, which employed crowdsourcing through a smartphone application to support the self monitoring of speech and voice changes, through the provision of human feedback, and the subsequent effect that this feedback had on self management practices. This study yielded positive responses from participants, who valued the anonymous feedback from the crowd and the support that this provided them in configuring their home based speech practice. A final discussion chapter draws the 3 case studies together and discusses the lessons learned throughout the research. It discusses the overall research questions for the thesis in detail and describes the implications of the research for the wider HCI and medical communities. A framework is presented which aims to visualise the levels of agency that the studied technologies afforded and the levels of responsiveness required by participants to make sense of, and implement the information being provided by the devices in order to facilitate a change to the self monitoring and management practices. Through the design and evaluation of the described technologies and a synthesis of the findings across the span of the research, this thesis explores the ways in which PwP, with a diverse range of symptoms and related physical, social and emotional issues, might value digital technologies and their potential to facilitate new forms of self monitoring and self management in their everyday lives.The National Institute of Health Research (NIHR): The Engineering and Physical Sciences Research Council (EPSRC): Gordon Chapman Memorial Fund

Curious Apothecary; An artists publication

“Prescriptions” was a juried exhibition of book art to supplement Martha Hall’s exhibition of works as part of Artists’ Books and the Medical Humanities symposium and workshop. The symposium, which launched Prescriptions, explored connections between artists' books, health/illness and medicine from interdisciplinary perspectives. The publication “Curious Apothecary” invites the viewer to create their own interpretation of the curious nature of the medical practices that took place in the 18th century and challenges the traditional processes of illustration through printmaking, while exploring its application in a more contemporary artists book format

Curious Apothecary; A screen-printed artists publication

After interviewing the archivist and investigating the historical apothecary ephemera found at the Thackery medical museum in Leeds, I created a number of individual illustrated responses to the information discovered to record and comment on the unusual medical practices of the 18thcentury. The work invites the viewer to create their own interpretation of the curious nature of the medical practices that took place in the 18th century and challenges the traditional processes of illustration through printmaking, while exploring its application in a more contemporary artists book format

DemYouth: Co-Designing and Enacting Tools to Support Young People’s Engagement with People with Dementia

There is a growing body of research examining the role of technology in supporting the care of—and relationships surrounding—people with dementia, yet little attention has been given to how this relates to younger family members. We conducted a qualitative study based on a series of 6 codesign workshops conducted with 14 young people who had personal experience with dementia. Initially, our workshops focused on understanding the difficulties that young people face when engaging, interacting and being with people with dementia. Initial analysis of workshop data informed the design of three digital tool concepts that were used as the basis for user enactment workshops. Our findings highlight the young people's desire to be more involved in their family discussions around dementia and a need for them to find new ways to connect with their loved ones with dementia. We offer a set of design considerations for future systems that support these needs and reflect on some of the complexities we faced around engaging young people in this difficult topic of discussion
