Instrument for measuring thin-film belt lengths
Instrument consists of base, vernier height gauge, sliding block, and balance-beam assembly with tension weight. Pulley bracket is provided with three pulley mounting holes, 4 inches apart, to accommodate widely different belt lengths. Instrument is accurate to within 0.001 inch and is suitable for commercial production
Chemometric modelling to relate antioxidants, neutral lipid fatty acids and flavour components in chicken breast
Relationships among quality factors in retailed free-range, corn-fed, organic, and conventional chicken breasts (9) were modeled using chemometric approaches. Use of principal component analysis (PCA) to neutral lipid composition data explained the majority (93%) of variability (variance) in fatty acid contents in 2 significant multivariate factors. PCA explained 88 and 75% variance in 3 factors for, respectively, flame ionization detection (FID) and nitrogen phosphorus (NPD) components in chromatographic flavor data from cooked chicken after simultaneous distillation extraction. Relationships to tissue antioxidant contents were modeled. Partial least square regression (PLS2), interrelating total data matrices, provided no useful models. By using single antioxidants as Y variables in PLS (1), good models (r2 values > 0.9) were obtained for alpha-tocopherol, glutathione, catalase, glutathione peroxidase, and reductase and FID flavor components and among the variables total mono and polyunsaturated fatty acids and subsets of FID, and saturated fatty acid and NPD components. Alpha-tocopherol had a modest (r2 = 0.63) relationship with neutral lipid n-3 fatty acid content. Such factors thus relate to flavor development and quality in chicken breast meat
Psychological symptomatology experienced by victims of sexual violence
This thesis examines the psychological symptomatology that male and female victims describe following their experiences of sexual violence. An introduction to the area provides definitions, prevalence rates and theories associated with sexual violence. In particular, rape trauma symptomology provides insight into the short and long-term symptoms of rape. An ecological perspective is also provided which considers sexual violence in terms of the interrelationships between the characteristics of the victim, the sexual violence itself and the social environment where recovery can take place. Chapter 1 provides a systematic literature review examining the range and measurement of psychological symptomatology of male victims. Findings highlighted male victims of sexual violence experience an array of negative and harmful psychological symptomatology. Chapter 2 provides a critique of a relevant psychometric assessment of trauma symptoms (Trauma Symptom Inventory). Findings of the critique highlighted that the TSI could be considered a reliable and valid assessment when examining trauma symptoms. Chapter 3 provides an empirical research study that examines and compares the types of psychological symptomatology male and female victims of sexual violence experience. Findings identified that male and female victims of sexual violence significantly associated different psychological symptoms to their experiences. Moreover, male victims significantly described more externalising symptoms in comparison to female victims, who described more internalising symptoms. Finally, Chapter 4 is a discussion of the implications of the thesis findings in relation to assessment, treatment and services for victims of sexual violence

Timing of Antiretroviral Therapy for HIV in the Setting of TB Treatment
The convergent human immunodeficiency virus (HIV) and tuberculosis (TB) pandemics continue to collectively exact significant morbidity and mortality worldwide. Highly active antiretroviral therapy (HAART) has been a critical component in combating the scourge of these two conditions as both a preemptive and therapeutic modality. However, concomitant administration of antiretroviral and antituberculous therapies poses significant challenges, including cumulative drug toxicities, drug-drug interactions, high pill burden, and the immune reconstitution inflammatory syndrome (IRIS), thus complicating the management of coinfected individuals. This paper will review data from recent studies regarding the optimal timing of HAART initiation relative to TB treatment, with the ultimate goal of improving coinfection-related morbidity and mortality while mitigating toxicity resulting from concurrent treatment of both infections

Staling in two canned lager beers stored at different temperatures from sensory analyses and consumer ranking
Two canned lagers, lager A (5% abv with late hop character) and lager B (4% abv) stored for 0, 7, 14, 21 and 28 days at 4, 12, 30 and 37°C were scored by trained sensory assessors (10) for liking and stale and related attributes of: cabbagy, cardboard, catty, grainy, honey, leathery, metallic, musty, skunky, and sour. Principal component analysis explained 80% data variance in 3 significant (p < 0.05) and 75% in 4 significant factors for A and B, respectively. In both lagers, aging correlated significantly with stale, cabbagy and musty and in A with metallic and sour and in B with catty and skunky. Partial least squares regression (PLS1) models showed good explanations: stale had regression coefficients of 0.88 (calibration) and 0.84 (validation) for A, and 0.96 and 0.91 respectively, for B; for liking 0.92 and 0.90 for A and 0.96 and 0.93 for B. For both lagers, liking was positively correlated with honey and grainy, and inversely with staling attributes. Lagers from 30°C were ranked for liking by 40 consumers against fresh as a hidden reference. Significant (p = 0.05) ranking of A, but not B, correlated with that of trained assessors
