Lumbar spine manipulation, compared to combined lumbar spine and ankle manipulation for the treatment of chronic mechanical low back painForbes, Lauren Hayley January 2009 (has links)
Dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic at the Durban University of Technology, 2009. / The low back and the lower limb are generally viewed as two isolated regions,
however, there are many authors who believe that these two regions are
functionally related. This is due to the two regions being connected to each other
through the kinematic chain of the lower extremity.
The lumbar spine is the link between the lower extremities and the trunk, and
plays a significant role in the transfer of forces through the body via the kinematic
chain. The physical link between the low back and the lower limb is supplied by
the thoracolumbar fascia, which plays an important role in the transfer of forces
between the spine, pelvis and legs.
Although a relationship between the lower extremity and low back pain is often
assumed, little research has been published to demonstrate the association. Most
of the evidence so far has been anecdotal, without scientific research to support it.
This study was designed to compare the relative effectiveness of lumbar spine
manipulation, compared to combined lumbar spine and subtalar manipulation for
the treatment of chronic mechanical low back pain, using subjective and objective
measures, for the management of chronic mechanical low back pain.
The study design was a quantitative clinical trial, using purposive sampling. It
consisted of forty voluntary participants with chronic mechanical low back pain.
There were two groups of twenty participants each, each of whom received six
treatments within a three week period. Group A received manipulation of the
lumbar spine only, whilst Group B received manipulation of both the lumbar spine
and subtalar joint.
The outcome measures included the response of the participants to the Numerical
Pain Rating Scale-101 and the Quebec Low Back Pain and Disability
Questionnaire. Objective data was obtained from three digital Algometer
measures. Data was collected prior to the initial, third and sixth treatment.
iv
Statistically both groups showed improvements, subjectively and objectively, with
regards to chronic mechanical low back pain. Inter-group testing for NRS over time
showed no significant effect for both treatment groups. There was a significant
treatment effect for Algometer Average TP1 while the treatment effect for
Algometer Average TP2 was not significant. However, inter-group testing for the
Quebec LBP over time showed no significant effect for both treatment groups.
Inter-group analysis demonstrated no statistical significance between the two
groups for subjective and objective measurements, thus suggesting that there is
no additional benefit in treating the subtalar joint in the management of mechanical
low back pain.
Further studies will also benefit greatly from the use of larger sample sizes to
improve statistical relevance of data.

An investigation to identify changes in power of the kayaking stroke following manipulation of the cervical spine in asymptomatic kayakersCuninghame, Neil Mark January 2009 (has links)
Dissertation in partial compliance with the requirements for a Master's Degree in Technology: Chiropractic, submitted to the Faculty of Health at the Durban University of Technology, 2009. / Although kayaking is an Olympic sport and said to be one of the top ten
growth sports in America, relatively little literature has been written on it by
sports scientists and there is a paucity of available literature. Previous
research has described the effects of spinal manipulation on muscles at
distant sites to the joint being manipulated, and there have been trends which
have shown a positive increase in strength and in muscle activity at these
sites. There has, however, been a lack of literature to show that these positive
trends would influence sporting performance in any way.
30 volunteer kayakers, who train and compete on a regular basis, were
actively recruited and randomly allocated into one of three groups. Group 1
received manipulation on a fixated cervical segment, group 2 on a non-fixated
cervical spine segment, and group 3 received placebo laser to the posterior
cervical area. Subjects were then required to complete two 200m sprint tests
on a kayak ergometer. Measurements were taken pre and post manipulation
and included maximum watts recorded for the duration of the sprint test and
time taken to complete 200m.
Although no statistically significant results were found between the groups,
trends revealed that in group 1, which received spinal manipulation on a
fixated joint, there was an increase in the mean peak watts post manipulation,
as compared to the placebo and non-fixated groups which showed a
decrease in peak watts post manipulation.
Group 1 also demonstrated a mean decrease in time taken to complete the
second 200m sprint test. Group 2 and 3 again showed an increase in time
taken to complete the second sprint test post manipulation.
iv
It is, therefore, concluded that manipulation of a fixated cervical joint in
asymptomatic kayakers results in an increase in performance, although it
must be noted that these were only trends and that there was no statistical
significance in these results. This research has, furthermore, opened the door
to future studies which may test the performance enhancing benefits of
competitive sports such as kayaking.

Kvartalsvisa resultatmönster : En studie av nordiska börsbolags tendenser till resultatmanipuleringEdlund, Martin, Persson, Eddie January 2014 (has links)
Uppsatsen undersöker om kvartalsvisa resultatmönster kan indikera potentiellt användande av resultatmanipulering (eng. earnings management). Företag klassificeras som Negativa-Positiva- (NP), Positiva-Negativa- (PN) respektive kontrollföretag beroende på hur resultatförändringar ter sig över ett helår. Med hjälp av den modifierade Jonesmodellen beräknas därefter företagens godtyckliga periodiseringar för att undersöka om NP- eller PN-företag är mer troliga än andra företag att tillämpa periodiseringsmanipulering. Ytterligare undersökningar genomförs med fokus mot faktisk resultatmanipulering (eng. real activities manipulation) genom test av godtyckliga utgifter, effektiv skattesats och produktionskostnader. Överlag påvisas signifikanta resultat för faktisk resultatmanipulering för NP-företag vilket indikerar att NP-företag är mer troliga än andra företag att manipulera resultatet.

Self-assembly and manipulation of nanorod arrays through liquid crystal functionalizationFeng, Xiang January 2015 (has links)
Self-assembly of nanorods (NRs) enhanced by functionalization with liquid crystals (LC) ligands has been demonstrated.
First, CTAB (cetyltrimethylammonium bromide) coated gold NRs were prepared in water through a modified one-step seed growth process. The hydrophilic GNRs were then converted into hydrophobic NRs employing a surface modification process using liquid crystalline organosilanes.
The functionalized GNRs were characterized by TEM (transmission electron microscopy) and SAXS (small angle X-ray scattering) to investigate the packing mode of the GNRs. The results propose models of the assembly of the GNRs depending on nature and connectivity of the attached liquid crystal molecules. Furthermore, a macroscopic orientation of the GNRs doped in LC was achieved via an alignment technique of the liquid crystal host. SAXS analysis of the doped DLC indicated modification of lattice parameters due to the insertion of the DLC-GNRs, which resulted in an enhancement of the charge carrier mobility.

Surfaced PrintArnbert, Camilla January 2015 (has links)
This bachelor degree work explores the interrelation between print and surface in fashion design and aims to investigate the expressional possibilities in merging of techniques. With focus on creating an irregular surface through embroidery and fringing, three-dimensional expressions are created, resulting in an illusion of depth and movement within the motifs. The work is textile-driven, hence the main focus has been to find materials, applicational techniques and motifs that interact with each other without conflicts. Through the use of heat sensitive yarns within the transfer printing process a clear relationship between texture and motif occur where the different aspects affect each other and are equally important for the final visual expression. It is the heat-press used to transfer print from paper to surface that is the most vital step of the process. This work strives to propose a transposed order of applying techniques within a design process. Whilst the act of embellishing existing prints has been investigated by a range of designers, this project propose an order where the print is added post additive surface-manipulation. Therefore this work is to be seen as a suggestion of new ways of approaching the use of prints within the fashion field. Balancing between fashion design and textile design, the collection is based on generic prints and shapes which are affected by the surface manipulations used.

"Copies without Originals": Manipulation, Mediation, and Mediatization in Performance and Recording PracticesMichaud, Alyssa R. 20 December 2012 (has links)
This thesis examines case studies and historical accounts taken from different periods of the history of recording technology, and addresses questions concerning the impact of mediatization, manipulation, and mediation on listeners' and performers' approaches to music. The project considers the development of the idea of "copies without originals," and of the ideological frameworks that have been used to describe and classify recorded sound. The first case study covers the early days of the phonograph and its development in Victorian society, then contrasts the values and motivations of those early years with modern-day rock performance and its own value systems. Moving into the mid-twentieth century, a chapter of this thesis is devoted to the work of Glenn Gould, and the possibilities for tape manipulation that the Canadian pianist explored during the period of his career that was focused on the recording studio. Lastly, this project examines the innovative, user-driven methods of music-making that are gaining momentum today, including Bjork's "Biophilia" app album, and the emergence of a new genre of popular music in Asia that uses vocal synthesizers in place of live performers. By exploring these case studies alongside the works of scholars in musicology, media studies, sound theory, film and television, and popular music studies, this thesis demonstrates how cultural need, individual innovation, and social involvement interact to direct the development and application of emerging media technologies.

Beauty and the Body: Gendered Representations of the Digitally Altered ImagePrince, Lauren 01 January 2014 (has links)
This work aims to explore how normalized gender representations in images are heightened through the use of digital manipulation technologies and how that influences a spectator’s relationship both to the image and to their own body. After constructing a theoretical understanding of the ways in which images influence and create a normative beauty ideology, a critical case study analysis of the ways celebrities are photographed and digitally altered provides for a grounding of theoretical material.
