This essay takes as its central argument that the bus can be viewed as a metaphor for the nation in Ben Okri’s "Stars of the New Curfew" and Karen King-Aribisala’s Kicking Tongues. The article unveils the numerous lexical and narrative correspondences between the realms of politics and public transport contained in the texts, and highlights how these associations interact with references to the stage to produce different, yet equally powerful, comments on contemporary Nigerian society.

Night-time airflow in a forest canopy near a mountain crest

Night-time airflow within a deep and dense canopy near the top of a mountain ridge is investigated based on measurements at Bily Kriz, Czech Republic. The site is characterized by a young Norway spruce forest on a 13 degrees slope and the occurrence of almost exclusively upslope or downslope flows. The forest canopy reaches the ground surface. A decoupled two-layer structure of canopy flow typically develops at night. While the above-canopy flow is most frequently an upslope-directed larger-scale flow over the ridge, the lower-canopy flow is downslope (katabatic). However, the lower-canopy flow can be forced upslope when the wind speed above the canopy exceeds a well-defined limit. Less frequently, on the lee slope to the larger-scale flow, both the above-canopy and the lower-canopy flow are usually downslope, although a flow reversal in the lower canopy is also observed, accompanied with a large shear stress (friction velocity) above the canopy. The occurrence of opposing flows is not limited to sunset/sunrise transition periods. In a simplified modelling approach to the dynamics of the nocturnal lower-canopy flow decoupled from above, local equilibrium is assumed of solely two opposing driving forces - one induced by the negative buoyancy (due to radiative cooling of the canopy) and the other by the hydrodynamic pressure gradient (resulting from the larger-scale flow over the ridge) - and the canopy drag as a retarding force. The diagnostic model gives realistic values of the major driving terms for Bily Kriz, and the downslope or upslope direction and speed of the lower-canopy flow that agree well with the measurements. The model contributes to better interpretation of the experimental results, which are in accordance with recent publications on the flow patterns on forested hills. Knowledge of the lower-canopy flow behaviour and of the degree of its decoupling from the flow aloft is necessary for assessing the contribution of advection to the CO2 budget at sloping forest sites, and for analysis of the flux footprint.

In this study we report the investigation of the nightglow molecular oxygen emissions of Venus in the visible spectral range, observed by the VIRTIS instrument (Visible and InfraRed Spectral Imaging Spectrometer) on board the Venus Express spacecraft. The Herzberg II system was detected in the range 0.4-0.7 µm. The observed bands peak at 95-96 km altitude, with a limb mode intensity of 15-20 kR for the strongest band, similar to that seen in previous observations. Simultaneous observations in the visible and IR [O2 (a-X) 1.27 µm band] were obtained in March 2007, and the two systems are similar in peak altitude. In addition, three bands of the O2 Chamberlain system, at 0.558, 0.604, and 0.657 µm were detected. They are well detached from the Herzberg II bands, and more distinct than reported in previous observations (Garcia Munoz et al., 2009). A simulated spectrum is obtained using the DIATOM code, allowing accurate reproduction of the observed VIRTIS mean spectrum. [less ▲]

Nightside reconnection at Jupiter: Auroral and magnetic field observations from 26 July 1998

In this study we present ultraviolet and infrared auroral data from 26 July 1998, and we show the presence of transient auroral polar spots observed throughout the postdusk to predawn local time sector. The polar dawn spots, which are transient polar features observed in the dawn sector poleward of the main emission, were previously associated with the inward moving flow resulting from tail reconnection. In the present study we suggest that nightside spots, which are polar features observed close to the midnight sector, are related to inward moving flow, like the polar dawn spots. We base our conclusions on the near-simultaneous set of Hubble Space Telescope (HST) and Galileo observations of 26 July 1998, during which HST observed a nightside spot magnetically mapped close to the location of an inward moving flow detected by Galileo on the same day. We derive the emitted power from magnetic field measurements along the observed plasma flow bubble, and we show that it matches the emitted power inferred from HST. Additionally, this study reports for the first time a bright polar spot in the infrared, which could be a possible signature of tail reconnection. The spot appears within an interval of 30 min from the ultraviolet, poleward of the main emission on the ionosphere and in the postdusk sector planetward of the tail reconnection x line on the equatorial plane. Finally, the present work demonstrates that ionospheric signatures of flow bursts released during tail reconnection are instantaneously detected over a wide local time sector. [less ▲]
