In this paper, Finite Element method and full-scale experiments have been used to study a hot forging method for fabri-cation of a spindle using reduced initial stock size. The forging sequence is carried out in two stages. In the first stage, the hot rolled cylindrical billet is pre-formed and pierced in a closed die using a spherical nosed punch to within 20 mm of its base. This process of piercing or impact extrusion leads to high strains within the work piece but requires high press loads. In the second stage, the resulting cylinder is placed in a die with a flange chamber and upset forged to form a flange. The stock mass is optimized for complete die filling. Process parameters such as effective strain distribution, material flow and forging load in different stages of the process are analyzed. It is concluded from the simulations that minor modifications of piercing punch geometry to reduce contact between the punch and emerging vertical walls of the cylinder appreciably reduces the piercing load. In the flange chamber, a die surfaces angle of 52° instead of 45° is pro-posed to ensure effective material flow and exert sufficient tool pressure to achieve complete cavity filling. In order to achieve better compression, it is also proposed to shorten both the length of the inserted punch and the die “tongues” by a few mm.

The goal of this dissertation was to examine how people pursue their personal goals in the context of an intimate relationship. Two studies were conducted; a daily diary study of dating partners’ joint activities and a longitudinal study of newly dating couples. In the daily diary study, people reported on their daily joint activities with their dating partners regarding whether their goals were met and how they were feeling during the given activity. The results showed that when people’s goals were met in an activity, their partners were able to accurately perceive that their goals were being met. However, when their goals were not met in the activity, their partners’ accuracy regarding their goals was only at chance levels. The partners’ overall levels of goal congruence did not predict the proportion of goal-congruent activities the partners participated in. However, the partners’ level of goal congruence predicted increases in life satisfaction, relationship commitment, and relationship satisfaction, as well as decreases in negative affect over time. In the longitudinal study, newly dating couples filled out measures of their goals, well-being, and relationship quality during their initial session. Three months later, the couples filled out measures of these same constructs again and answered questions about the goals that they reported pursuing during their initial session. Results showed that concurrently, the partners’ levels of goal congruence were associated with greater ability to make goal progress and higher relationship satisfaction, both of which, in turn, were associated with higher subjective well-being. Longitudinally, initial levels of goal congruence did not predict changes in goal progress and relationship quality over time. However, analysis of the individual goals indicated that people adjusted their goal pursuits based on the level of goal conflict between their own goals and their partners’ goals, such that people were more likely to stop pursuing or devalue goals that conflicted with their partners’ goals over time. Furthermore, the tendency to adjust goals over time was associated with increasing relationship commitment. The results of these studies show that conflict between relationship partners’ goals has important consequences for their relationship, goal progress, and personal well-being.

"Uncanny Affects" argues, broadly, that the gothic novel of the eighteenth and nineteenth centuries models a critical ethics of reading. By examining recurrent scenes of reading and interpretation in key gothic novels such as Ann Radcliffe's The Italian (1797), Walter Scott's The Antiquary (1816), and Wilkie Collins' The Moonstone (1868), I surmise that this critical ethics posits affect, or the experience of generalized emotion, as central to the act of interpretation. I contend that this gothic critical ethics influences the concurrent development of the discipline of literary criticism. By reading these key gothic novels and then tracking their broader influence on Victorian critics such as John Ruskin and Oscar Wilde, I make a case for the significance of a gothic epistemology to the development of literary criticism in British and American universities from the nineteenth century onward. A focus on the gothic novel's critically inclined characters, including antiquarians and detectives, enables me to read gothic novels and other gothically-inflected writing for what they can tell us about the practice of interpretation, particularly as that practice becomes institutionalized and professionalized. Thus I track the gothic mode's tendency toward affective reading in relation to ideas of professionalization, which values critical detachment or disinterestedness in interpretation. As a result, interpretation in the gothic mode can seem too emotional or "creative" for a typically professional practice. Reading the gothic as such links it to modern discussions about interpretive practices such as close reading, paranoid and reparative reading, and surface reading. Perhaps more importantly, reading the gothic alongside these new discussions on critical ethics allows us to think through the place of affect and pleasure in an ethical critical practice. Ultimately, examining how gothic texts formulate a gothic mode or philosophy of reading demonstrates the real ubiquity this mode has achieved in the critical setting, a ubiquity that continues to shape and influence our conceptions of scholarly and critical reading even today. / text

This thesis presents a qualitative analysis of the Marine experience in the Korean War with air power. Evidence suggests that Marine Close Air Support in the early months of the Korean War was superior to Navy and Air Force CAS. The Marine Corps collected interviews during the war, which support this conclusion. Interviews were taken with pilots, commanders, tactical air coordinators, forward air controllers, mechanics, infantrymen and other front line soldiers who experienced the CAS in the opening months of the war. Many factors contributed to this qualitative difference including; training, doctrine, control system, and type of planes used. This qualitative difference amounted to the superiority of Marine CAS in the opening months of the Korean War. / Department of History

The diagnosis of HIV is a life-changing event that requires people to deal with the disease, as well as cope with HIV stigma. Both people living with HIV or AIDS (PLHA) and their close family members (CFM) are stigmatized, but CFM also stigmatizes PLHA. This interaction affects the relationship between PLHA and their CFM. The aim of this study was to evaluate the effect of a comprehensive community-based HIV stigma reduction intervention on PLHA and their CFM as well as to explore and describe their experiences during and after the intervention. A holistic multiple case study design as well as a qualitative description approach was used. The study was conducted in both an urban and a rural setting. Purposive sampling was used for the PLHA and snowball sampling for the CFM. The case record for the case study consisted of several sources. In-depth-interviews were used to explore their experiences. The data was analysed using open coding and text document analysis. Both groups gained a richer understanding of HIV stigma and coping with it. The relationships enriched by PLHA feeling more supported and CFM realizing how they stigmatized and that they should be more supportive. Leadership was activated through the project. Bringing PLHA and CFM together during an intervention, proved to be affective, Recommendations focus on the inclusion of HIV-related stigma reduction awareness interventions in the curriculum of student nurses and the implementation thereof in the community, through community based nursing. It would be of benefit if the programme could also be offered as a workshop to traditional healers in the community. Nurses in clinics working with PLHA should invite PLHA and CFM to participate in groups to support each other in reducing HIV-related stigma and share problem-solving coping strategies. The researcher believes that the results of the current study have important implications for further research in HIV-related stigma reduction interventions in other countries and demographic groups. It has the potential to be used for long-term monitoring studies of HIV stigma reduction interventions and the change over time. / Thesis (MCur)--North-West University, Potchefstroom Campus, 2013

This thesis reports photometric and spectroscopic studies of three close binary systems; BP Velorum, V392 Carinae and V752 Centauri. BP Velorum, a W UMa-type binary, was observed photometrically in February 2007. The light curves in four filters were fitted simultaneously with a model generated in the eclipsing binary modeling software package PHOEBE. The best model was one with a cool star spot on the secondary larger component. The light curves showed additional cycle-to-cycle variations near the times of maximum light which may indicate the presence of star spots that vary in strength and/or location on a time scale comparable with the orbital period, (P = 0.265 d). The system was confirmed to belong to the W-type subgroup of W UMa binaries for which the deeper primary minimum is due to an occultation. V392 Carinae, a detached binary with an orbital period of 3.147 d, was observed photometrically by Michael Snowden in 1997. These observations were reduced and combined with the published light curve from Debernardi and North (2001). High resolution spectroscopic images were taken using the University of Canterbury's HERCULES spectrograph. The radial velocities measured from these observations were combined with velocities from Debernardi and North (2001). The radial velocity and light curves were fit simultaneously, confirming that V392 Car is a detached system of two main sequence A stars with a mass-ratio of 0.95. The derived systematic velocity is consistent with V392 Car being a member of the open cluster NGC 2516. The W UMa-type binary V752 Centauri was observed photometrically and spectroscopically during 2007. The high resolution spectra displayed weak sharp lined features superimposed over the strong broad lined spectrum expected from the 0.370 d contact binary. Fourier methods were used to separate the broad and sharp spectral features and radial velocities for each were measured by cross-correlation. A fit to the photometry and radial velocities for the contact binary implied a system of two late F stars with a mass-ratio of 3.38 in an over-contact configuration. The derived systematic velocity (−13.8km/s), has changed significantly from the 1972 value (29.2km/s). The third (sharp lined) component's radial velocities were measured and found to have a period of 5.147 d, semi-amplitude of 43.4km/s and systematic velocity of −7.3km/s. The likely configuration of the entire system is that of a contact binary in a long period orbit about a lower mass detached binary. V752 Cen is thus a triple lined spectroscopic quadruple.
