Impervious surfaces (IS) are a key indicator of environmental quality, and mapping of urban IS is important for a wide range of applications including hydrological modelling, water management, urban and environmental planning and urban climate studies. This paper addresses the accuracy and applicability of vegetation indices (VI), from Landsat imagery, to estimate IS fractions for European citi...

Vegetation was added to a fully-developed sandy point bar in the meander of a 5 constructed stream. Significant changes in the flow structure and bed topography were observed. 6 As expected, the addition of vegetative resistance decreased the depth-averaged streamwise 7 velocity over the bar and increased it in the open region. In addition, the secondary circulation 8 increased in strength, but...

Herbaceous weed control (HWC) is prescribed for growing season control of vegetative competition in hardwood afforestation attempts on former agricultural areas. Without HWC, planted seedlings often exhibit poor growth and survival. While currently employed HWC methods are proven, there is a substantial void in research comparing HWC treatments spanning multiple years. A total of 4,320 bare-roo...

The aim of this study was to evaluate the effects of the foliar application of zinc (15, 30 and 50 mg/L) and iron (50 and 100 mg/L) and their combination on vegetative, reproductive growth, fruit quality and yield of cucumber plants as a factorial in completely randomized block design with four replications. Results indicated that different applied treatments significantly increased vegetative ...

This study explores the connections between vegetation cover change, environmental stewardship, and building footprint change in New York City neighborhoods from the years 2000 to 2010. We use a mixed-methods multidisciplinary approach to analyze spatially explicit social and ecological data. Most neighborhoods lost vegetation during the study period. Neighborhoods that gained vegetation tended...

We introduce the use of remote sensing analysis in providing new insight in characterizing green turtle nesting habitat. A maximum likelihood classification (MLC) and a multiple endmember spectral mixture analysis (MESMA) were conducted on a Landsat image that contained six nesting beaches in Turkey that represent varying degrees of importance. Both techniques highlighted similarities of the ve...

It is one of the fundamental problems of the researches on schizophrenia to find out those elements of the brain, which by deterioration cause the symptoms of schizophrenia . Some clinical experts, who, by studying vegetative phenomenons have got their concept of the nature of schizophrenia, think, that the central vegetative regions play a special and important part in causing schizophrenia . ...

The potential for directional optical and thermal imagery is very large. Field measurements have been performed with a goniometer on which thermal instruments were attached. In order to reduce dynamical effects the goniometer was adjusted to run in automated mode, for zenith and azimuthal direction. Directional measurements were performed over various crops with increasing heterogeneity. The im...
