Meteosat and GOES-East Imager Visible Channel Calibration
|
ABSTRACT
As a preliminary step to solar irradiance calculations, the Centre de Météorologie Spatiale (CMS) has developed a pragmatic approach to calibrate the visible channels of Meteosat and GOES-East imagers. The responsivity of the Meteosat visible channel has been monitored with three desert targets from 1989 to 2002. The annual degradation rate has been estimated to 1.8% for Meteosat-4, 1.4% for Meteosat-5, and 1.9% for Meteosat-7. A reference calibration coefficient for Meteosa...

Recycling of remediated soil for effective composting of diesel-contaminated soil
Compost Science & Utilization
; Soil contaminated with diesel oil was remediated by the addition of remediated soil. Several mix ratios of contaminated soil to remediated soil were tested. Judging from TPH degradation rate and biochemical parameters, the optimum mix ratio (wet weight basis) was 1:1. In this mix ratio, the first

BIODEGRADATION - In vivo degradation and biocompatibility study of in vitro pre-degraded as-polymerised polylactide particles
Biomedical Materials
; The histological response of as-polymerised poly L-lactide (PLLA), PLLA with 4% D-lactide (PLA96), and cross linked PLLA (CL-PLLA) pre-degraded materials show a good similarity with in vivo implanted material. Pre-degraded PLLA induced a mild foreign body reaction and showed a slow degradation

Measurement and prediction of permethrin persistence in six Malaysian agricultural soils.
Australian Journal of Soil Research
; Introduction The fate of pesticides in soils is greatly influenced by their interaction with the soil environment. It is now well established that the persistence of most pesticides is influenced by the organic matter content of the soil (Blumhorst et al. 1990) and other environmental factors, such

A study on the in vitro degradation of poly(lactic acid) (PLA)
Biomedical Materials
; From the molecular weight versus the degradation time data, a degradation rate was defined, normalized to the molecular weight of the polymer at each time. The behaviour of the degradation rate curves, plotted against the degradation time, was interpreted and compared to the initial physical and

BIODEGRADATION - Polymers for biodegradable medical devices. VIII. Hydroxybutyrate -hydroxyvalerate copolymers: physical and degradative properties of blends with polycaprolactone
Biomedical Materials
; In this study the degradation rate of hydroxybutyrate - hydroxyvalerate copolymer/polycaprolactone blends was found to be influenced by a complex set of factors including temperature, pH, and polycaprolactone content of the blend. Although crystallinity was found to affect the mechanical properties

Ruminal in vitro degradation of protein in tannin-free and tannin-containing forage legume species.
Crop Science
; Protein in many forage legumes often is poorly utilized by ruminants because of extensive breakdown to non-protein nitrogen (NPN) compounds during harvest and storage, followed by further degradation in the rumen (NRC, 1989). Although NPN can be incorporated into protein by ruminal microbes, and
