Longitudinal variation in the axial muscles of snakes
… to the skull. However, this and other aspects of longitudinal variation in axial muscle morphology are poorly documented either within or between species of snakes. For the anterior half of the trunk in 25 phylogenetically and morphologically diverse species of snakes, we compared patterns of …

Radial and longitudinal variation of the mechanical properties of bamboo
… there is a need to better understand the variation in the plant's mechanical properties. The microstructure of bamboo and the mechanical properties of the solid cell wall material of bamboo were characterized for use in models for the variation of the overall mechanical properties of …

Longitudinal Variation in Fish Community Along the Upper Green River Below the Green River Lake
… of flowing waters can cause decreased variation in flow and temperature, reduce habitat availability, and decreased mean temperature below a reservoir. These types of alterations can influence fish communities. Twelve sites were sampled along the Upper Green river in order to address …

Longitudinal variation in environmental impact at rock climbing areas in the Red River Gorge limits of acceptable change study area, Daniel Boone National Forest, Kentucky
<p>Recreation ecology began in the 1960s to measure the impacts of recreation on ecosystems. Area of environmental impact is an important objective to assess recreational impact. However, few researchers have examined the trends of these impacts over time. This study measures the environmental area …

AN ANALYSIS OF LONGITUDE VARIATIONS IN THE EQUATORIAL SPECTRUM OF SATURN
… and ammonia bands are analyzed to search for longitudinal variations in Saturn's equatorial region. A model with reflecting layer at 2.1 bars, an extended haze to 170 mb and an overlying thin stratospheric haze is adopted. Two sets of data are analyzed, a set of ground based observations …

Spatial and temporal distribution of larval fishes in a large tidal river.
… a result of changes in discharge. Spatial (i.e. longitudinal) variation of the larval fish assemblage differed by tidal regime. NMS and MRPP identified a distinct tidal freshwater larval fish assemblage. Tidal freshwater habitats may act as ecotones between marine and riverine ecosystems.

Material characterization of Guadua bamboo and the environmental feasibility of structural bamboo products
… This study aims to characterize the radial and longitudinal variation in the microstructure and mechanical properties of Guadua bamboo (Guadua angustifolia kunth) in order to inform efficient material use in a composite. The study found a linear relationship between the MOE, MOR, and compression …

Biomechanical Analysis of Human Coronary Atherosclerotic Plaques in Response to Pharmacotherapy, and in Predicting Adverse Clinical Events
… that plaque geometric parameters, especially the longitudinal variation measured by heterogeneity index of lumen roughness, curvature, and irregularity, can identify plaques that subsequently developed adverse clinical events. Lumen roughness heterogeneity showed a weak correlation with PSS and …

Sequential data inference via matrix estimation : causal inference, cricket and retail
… a unified framework to capture the temporal and longitudinal variation across multiple instances of sequential data. Examples of such data include sales of a product over a period of time across several retail locations; trajectories of scores across cricket games; and annual tobacco consumption …

Development and applications of dispersion controlled high nonlinearity microstructured fibres
… work has been focussed on controlled structural variation of holey fibres along their length to obtain fibre with a longitudinal variation of dispersion and nonlinearity. I fabricated a dispersion-decreasing holey fibre and performed the first demonstration of soliton compression in a holey …

Patterns in Fish Community Structure in a Regulated River
… that the small amount of fish community variation observed supports the possibility that the present assemblage has adapted to a regulated flow regime, however a direct relationship between peaking and community composition cannot be established. Additionally, fishes were sampled at three …

Evolution of chemical composition along river drainage networks
… studied in order to understand the controls on longitudinal variation of stream chemistry. In the Rio Icacos-Blanco system in Puerto Rico, I examined changes in stream chemistry associated with a change in bedrock composition from intrusive quartz diorite (upstream) to volcaniclasitc material …
