The impacts of such water transfers are expected to vary temporally and spatially. The aim of this paper is to specify a method to assess these impacts. Although water trading and its impacts have been discussed qualitatively in the literature; there are limited qualitative models available. In the past economists primarily modeled water trading without considering biophysical and systemic cons...

Empirical models are important tools for relating field-measured biophysical variables to remote sensing data. Regression analysis has been a popular empirical method of linking these two types of data to provide continuous estimates for variables such as biomass, percent woody canopy cover, and leaf area index (LAI). Traditional methods of regression are not sufficient when resulting biophysic...

Based on the physico-biophysical considerations, mathematical analysis and some approximate formulations generally adopted in meteorology and ecology, an ecological dynamic model of grassland is developed. The model consists of three interactive variables, i.e. the biomass of living grass, the biomass of wilted grass, and the soil wetness. The major biophysical processes are represented in para...

Many fluorescent proteins are currently available for biological spectroscopy and imaging measurements, allowing a wide range of biochemical and biophysical processes and interactions to be studied at various length scales. However, in applications where a small fluorescence reporter is required or desirable, the choice of fluorophores is rather limited. As such, continued effort has been devot...

This study investigates the scientific quality of the first version of global biophysical products (FCover, LAI, FAPAR) developed in the Geoland-2 /BioPar Core Mapping Service, namely GEOV1. These products based on SPOT/VEGETATION data were built on MODIS and CYCLOPES products while reconciling their differences. The quality assessment strategy follows the CEOS/WGCV Land Product Validation guid...

Mangroves are one of the most productive coastal communities in the world. Although we acknowledge the significance of ecosystems, mangroves are under natural and anthropogenic pressures at various scales. Therefore, understanding biophysical variations of mangrove forests is important. An extensive field survey is impossible within mangroves. WorldView-2 multi-spectral images having a 2-m spat...

BACKGROUND This paper examines if, when controlling for biophysical and geographical variables (including rainfall, productivity of agricultural lands, topography/temperature, and market access through road networks), socioeconomic and health care indicators help to explain variations in the under-five mortality rate across districts from nine high focus states in India. The literature on this ...

This research aims to analysis the biophysical characteristics of watershed of Deli River to know potential flooding in Medan. The research is conducted at Deli River, which is located in 3 locations in North Sumatera namely Karo Regency, Deli Serdang and Medan City. Indonesia. This research used field survey method, survey activity in the form of observation and verification of characterizatio...

Background and Aim: Dermatitis or eczema is an itchy skin disorder which is usually caused by the skin inflammatory reaction in response to combination of genetic and environmental factors. This study was aimed to assess the safety of anti-dermatitis creams and possible side effects on human volunteers through measuring the skin biophysical parameters with non-invasive methods. Methods: Two ...
