Friend or Foe? International Environmental Law and its Structural Complicity in the Anthropocene’s Climate Injustices

In this paper, we focus on the structural complicity of international environmental law (IEL) in causing and exacerbating climate injustices. We aim to show that although the intentions behind IEL may be well-meaning, it often inadvertently, but also deliberately at times, plays a role in creating, sustaining and exacerbating the many paradigms that drive climate injustice in the Anthropocene. We focus on three aspects: IEL’s neoliberal anthropocentrism; its entanglement with (neo)colonialism; and its entrenchment of the sovereign right to exploit energy resources. We conclude with a call for thoroughgoing, and urgent, reform of IEL

Measurement and prediction of wave-generated suborbital ripples

Experiments in a large-scale wave flume using regular and irregular waves with periods between 4 s and 6 s and heights between 0.2 m and 1.55 m have examined the formation of wave-generated ripples using sediment beds composed of four grain sizes (D50 = 0.349 mm, 0.329 mm, 0.220 mm, and 0.162 mm) in a water depth of approximately 4 m. Estimates of wave-generated ripple height,?, and wavelength, ?, were obtained using zero down-crossing analyses of bed profiles measured by acoustic means along a 4-m transect normal to the ripple crests. Further information pertaining to ? was obtained from bed images obtained using scanning sonar. The analyses reported here focus on the sequence bedforms that evolved in response to stepwise increases and decreases in wave height. Results show that ripples for the most part are suborbital in nature and do not conform well to empirical equations used frequently to predict ? and ? values in the field. On the basis of the present data, two new equations for prediction of ? and ? are obtained and their use in field situations where hydrodynamic and sedimentary conditions favor development of suborbital bedforms is recommended

Rapid molecular methods for enumeration and taxonomical identification of acetic acid bacteria responsible for submerged vinegar production

The aim of the present study was to search for a rapid and reliable method to enumerate viable acetic acid bacteria (AAB) and to identify to genera and species level AAB isolates from vinegars in full acetic fermentation elaborated by the submerged method from cider, wine and spirit ethanol in industrial bioreactors. Results showed that the rapid epifluorescence staining method using the LIVE/DEAD BacLight bacterial viability kit and direct counts in Neubauer chamber rendered consistent and reliable data for viable cell counts of bacteria in all the studied vinegars. A linear correlation was shown between viable cell counts and fermentation rates. The highest fermentation rates and viable cell counts were found in cider vinegars, whereas spirit vinegars showed the lowest values for both parameters. Eighty-four AAB pure isolates were recovered from 41 different vinegar samples and were submitted to DNA extraction. PCR amplification of the 16S-23S intergenic spacer region of rDNA and subsequent sequencing were carried out to identify isolates to species level. Results showed that Gluconacetobacter europaeus was the predominant cultivable species, appearing in 79% of the total isolates. This was the unique species found in spirit vinegars, and this is the first time that AAB from spirit vinegars are taxonomically identified. Ga. europaeus was as well the predominant cultivable species in white wine vinegars. Cider vinegars presented the highest variability of species: Ga. europaeus (35.3% appearance among cultivable isolates), Ga. xylinus (35.3%), Acetobacter pasteurianus (17.6%) and Ga. hansenii (11.8%). Red wine vinegars showed cultivable isolates of the species Ga. xylinus (71.4%) and Ga. europaeus (28.6%). Summarising, both described methods for AAB enumeration and taxonomical identification proved to be fast and reliable methods, and results revealed Ga. europaeus as the cultivable major species in vinegars in full fermentation conducted by the submerged method, suggesting that Ga. europaeus strains can constitute excellent starter cultures for the elaboration of vinegars by the submerged method. © 2010 Springer-Verlag
