Cerebrum dispersio tab6/28/2023 Diffusion-tensor imaging metrics of the corona radiata were correlated with ventricular size in 14 adult patients with acute hydrocephalus, 16 patients with long-standing hydrocephalus, and 48 consecutive healthy adult subjects. In this article, we investigated this relationship in adult patients with hydrocephalus and in healthy adult subjects. Because ventricular size is a common measure of the severity of hydrocephalus, we hypothesized that a quantitative correlation could be made between the ventricular size and diffusion-tensor changes in the periventricular corona radiata. Understanding the nature of these changes may aid in the diagnosis and treatment planning of this relatively common neurologic condition. Hydrocephalus causes changes in the diffusion-tensor properties of periventricular white matter.

Findings suggest that white matter microstructure of the corona radiata is a neural correlate of several, but not all, attention dimensions. Results suggest that greater microstructural white matter integrity of the corona radiata is partly associated with attention across 4 attention dimensions. Significant correlations were found between the focus/execute, sustain, stabilize, and shift dimensions and imaging metrics in hypothesized corona radiata subregions. Partial Pearson correlations between neuropsychological standardized scores, representing these attention dimensions, and diffusion tensor imaging measures of corona radiata subregions were calculated after adjusting for gender and IQ. Diffusion tensor imaging maps were analyzed using standardized parcellation methods. Diffusion tensor imaging and neuropsychological assessments were conducted in 79 healthy, right-handed youth aged 4-17 years. The neural correlates of these dimensions were investigated within corona radiata subregions in healthy youth. Mirsky proposed a model of attention that included these dimensions: focus/execute, sustain, stabilize, encode, and shift.

With the slope stability model SOSlope, information on the intensity and frequency of harvesting and on the development of weak zones that can be supported by a stand of Pinus radiata in relation to slope stability can be calculated. Using the Root Bundle Model, results of our measurements allow estimation of root reinforcement. We fully excavated the root system of two trees. We also measured root distribution data from 5 plants, digging arc of circles 0.6 radian around the trees in four opposite directions. We measured soil moisture and carried out 30 field tensile tests on roots of Pinus radiata. Yet, little is known about root distribution and tensile strength for this specie. This information is needed to use the state of the art root reinforcement model (the Root Bundle Model) and the physically-based slope stability model SOSlope. Bio-engineering traits such as root distribution and root tensile strength are fundamental to understand the effectiveness of Pinus radiata. Due to steep slopes and intense rainfall, the silviculture of Pinus radiata forests is important to control erosion and slope stability. Pinus radiata is widely cultivated in New Zealand.
