Abstract:

Power system generators are interconnected in a distributed network to allow sharing of power. If one of the generators cannot meet the power demand, spare power is diverted from neighbouring generators. However, this approach also allows for propagation of electric disturbances. An oscillation arising from a disturbance at a given generator site will affect the normal operation of neighbouring generators and might cause them to fail. Hours of production time will be lost in the time it takes to restart the power plant. If the disturbance is detected early, appropriate control measures can be

The present study investigated the use of the Maternal Perinatal Scale (MPS) as an instrument for predicting group membership among normal versus emotionally handicapped children. An examination of neurological symptoms as they relate to specific behavioral factors within the Child Behavior Checklist (CBCL) was conducted, as well as an investigation of the relationship between factors within the MPS as predictors of specific behaviors within the CBCL. Subjects included 119 EH students and 211 normal subjects with a mean age of 10 years, 3 months. Samples were collected from a suburban midweste

Abstract:

Background: Insomnia is a robust correlate of suicidal ideation and behavior. Preliminary research has identified thwarted belongingness (c.f. social disconnection) as an explanatory link between insomnia and suicidal ideation. Objectives: This study replicates and extends previous findings using both cross-sectional and longitudinal designs in four demographically diverse samples. Additionally, the specificity of thwarted belongingness was evaluated by testing anxiety as a rival mediator. Method: Self-report measures of insomnia symptoms, thwarted belongingness, suicidal ideation and behavior

Abstract:

Slope stability assessments are classical problems for geotechnical engineers. The predictions of slope stability in soil or rock masses play an important role when designing for dams, roads, tunnels, excavations, open pit mines and other engineering structures. Stability charts continue to be used by engineers as preliminary design tools and by educators for training purposes. However, the majority of the existing chart solutions assume the slope problem is semi-infinite (plane-strain) in length. It is commonly believed that this assumption is conservative for design, but non-conservative whe

Anthropogenic disturbances can alter the abiotic composition of freshwater systems. These compositional changes can act as physiological stressors towards system inhabitants. However, little is known about how these altered abiotic factors influence stress hormones (corticosterone) in larval amphibians. Throughout the following chapters, I examined the effects of several abiotic factors on baseline and stress-induced corticosterone levels in the larvae of four amphibian species: Jefferson salamander (Ambystoma jeffersonianum), spotted salamander (A. maculatum), wood frog (Rana sylvatica), and

Due to overgrazing, mining and other anthropogenic disturbances, large sections of the Karoo region have been degraded, resulting in areas with low vegetation cover, where erosion rates are high and vegetation is dominated by unpalatable species. These areas have low and unpredictable rainfall, with slow to non-existent autogenic recovery, and this often forces landowners to implement reseeding rehabilitation in an attempt to increase both overall vegetation cover and the relative abundance of palatable plants.

Abstract:

Cornelia de Lange syndrome (CdLS) is a rare disorder characterized by an extensive clinical heterogeneity. The main features of the syndrome are characteristic facial dysmorphisms and a variable level of intellectual disability, growth retardation and developmental delay. Though, the number and severity of the clinical signs vary among patients. An extensive genetic heterogeneity partially accounts for the reported clinical variability. Mutations in different cohesin-associated proteins are in fact responsible for the onset of the syndrome. The known CdLS-genes include NIPBL, SMC1A, SMC3, RAD2

Abstract:

Abstract Deciduous shrubs form the tallest type of vegetation in arctic-alpine areas and are important for ecosystem function. In the southern part of the Eurasian tundra zone, willows (Salix spp.) are the most common species in the shrub layer. In the alpine areas of Northern Fennoscandia, willow shrubs are characteristic to areas between tree line and treeless tundra heaths. Vertical structure and composition of willow-characterized tundra vegetation is affected by a variety of ecological factors including climate and herbivory. In turn, the abundance of the willow canopy affects understory

Abstract:

Species have complex and contextual relationships with their environment; both the relative contributions of life-history stages to population growth and the effect of environmental factors on each stage can be different among co-existing species. Timing and extent of reproduction, survival, and mortality determine population growth, species distributions, and assemblage patterns. I evaluate the role of habitat (intact, degraded) and microsite (shrub, leaf litter, bare sand) on population dynamics of Florida scrub herbs. Isolated overgrown shrubs and extensive bare sand areas in degraded scrub

Abstract:

This cross-sectional quantitative study was conducted to assess the presence of muscle dysmorphia (MD) and a drive for muscularity (DFM) in 1,039 personal trainers using the Muscle Dysmorphia Inventory (MDI) and the Drive for Muscularity Scale (DMS). Muscle dysmorphia is considered a subtype of body dysmorphic disorder that can be exacerbated by an intense DFM, which may in turn lead to negative psychobehavioral outcomes. Because personal trainers are an unresearched population with regard to these 2 constructs, a multidisciplinary framework was used to ground the present research study. Indep
