Urban Atmospheres [PDF]

open access: yescultural geographies, 2017
What is an urban atmosphere? How can we differentiate an ‘atmosphere’ from other facets of urban consciousness and experience? This essay explores some of the wider cultural, political, and philosophical connotations of atmospheres as a focal point for critical reflections on space and subjectivity.

Migration dynamics of juvenile southern bluefin tuna

open access: yesScientific Reports, 2018
Large scale migrations are a key component of the life history of many marine species. We quantified the annual migration cycle of juvenile southern bluefin tuna (Thunnus maccoyii; SBT) and spatiotemporal variability in this cycle, based on a multi ...

The isothermal layer of the atmosphere and atmospheric radiation [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1909
Abstract The investigation of the upper air by means of balloons carrying self-recording instruments, which have furnished values for the atmospheric temperature up to heights between 15 and 20 kilometres, has revealed the existence of an abnormal change in the vertical temperature gradient.

Modeling the signature of sulfur mass-independent fractionation produced in the Archean atmosphere [PDF]

open access: yes, 2014
Minor sulfur isotope anomalies indicate the absence of O2 from the Archean atmosphere. A rich dataset showing large variations in magnitude and sign of Δ33S and Δ36S, preserved in both sulfates and sulfides, suggests that further constraints on Archean ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Oceanic planetary waves in the coupled ocean-atmosphere system [PDF]

open access: yes, 2005
The propagation of planetary, or Rossby, waves is studied under the effects of different atmospheric couplings. First, analytical matchings are formulated in which a Rossby wave is coupled to different thermodynamical atmospheres, from a simple heat flux
