Environmental or 'ecological' footprints have been widely used in recent years as indicators of resource consumption and waste absorption presented in terms of biologically productive land area [in global hectares (gha)] required per capita with prevailing technology. In contrast, 'carbon footprints' are the amount of carbon (or carbon dioxide equivalent) emissions for such activities in units ...

Grassland health assessment (GHA) is a bridge of study and management grassland ecosystem. However, there no standardized quantitative indicators long-term monitor methods for GHA at large scale, which may hinder theoretical practical application GHA. In this study, along with previous concept practices (i.e., CVOR, the integrated indexes condition, vigor, organization resilience), we proposed ...

ecological footprint analysis in agriculture is a new and evolving subject. the main purpose of the study was to assess environmental sustainability of conventional and conservation tillage systems using ecological footprint analysis in hamedan province. global hectares (gha) were used to measure the ecological footprint unit. data was collected through questionnaires and use of cross-sectional...

The effects of Beauveria bassiana strain GHA, applied as BotaniGard ES, on newly colonised and well-established populations of emerald ash borer, Agrilus planipennis (Coleoptera: Buprestidae) were evaluated in the field using foliar and trunk sprays in Michigan in 2004 2005. Results from field trials at a newly colonised white ash site showed a 41% reduction in A. planipennis population in fung...

we separated platelets from whole blood and incorporated them into in-ill and te-99m agents. sn-gha, tropolone, oxine (sulphate) and hmpao were used to diffuse radionuclides into the platelets. the effects of time, temperature, ph of incubation media; volume and concentration of ionophore; and volume and activity of ln-l 13m c13 and te-99m on labeling efficiency were studied.

The mol-ecular structure of the title compound, C(6)H(5)BF(2)O(2), is essentially planar (mean deviation = 0.019 Å), indicating electronic delocalization between the dihydroxy-boryl group and the aromatic ring. In the crystal structure, inversion dimers linked by two O-H⋯O hydrogen bonds arise. An intra-molecular O-H⋯F hydrogen bond reinforces the conformation and the same H atom is also involv...

Wooden furniture production consumes a lot of forest resource and other resources, so it is important to estimate its environmental effect. In this research, we collected data in sofa factory China appraised environment impacts by the ecological footprint (EF) methodology. The results showed that total EF was 2 316.25 gha/year (gha: global hectare). average 0.18 gha/year. For factory, main cont...

Dobriner, Rhoads, and Lavin (8, 9) isolated from the excreta of rats injected subcutaneously with 1,2,5,6_dibenzanthracene 1 a phenolic compound which was later shown by Cason and Fieser (3) to have an absorption spectrum identical with that of synthetic 4',8'-dihydroxy-i,2,5,6-dibenzanthracene (Fig. z); the same phenolic derivative was also present in the excreta of mice which had received sim...

BACKGROUND Principal component analysis (PCA) has been widely employed for automatic neuronal spike sorting. Calculating principal components (PCs) is computationally expensive, and requires complex numerical operations and large memory resources. Substantial hardware resources are therefore needed for hardware implementations of PCA. General Hebbian algorithm (GHA) has been proposed for calcul...

Secure determination of the binding of 99mTc-radiopharmaceuticals to plasma (P) and blood cell (BC) constituents can help to understand the biodistribution of radiophamaceuticals. The reported precipitation studies of blood with radiopharmaceuticals have shown that the results can not be easily compared between studies. We decided to determine the "gold standard" concentration of trichloroaceti...
