The world is experiencing new relations and transformations between natural, synthetic, digital substances. Rather than considering these as materially distinct or ontologically separate, this Special Issue of TSANTSA interrogates how they are interlocked in socio-material processes mediation, transmutation, valuation. By conceptualizing the specificity their separateness, special issue makes p...

Deep inspirations (DIs) taken before an inhaled challenge with a spasmogen limit airway responsiveness in nonasthmatic subjects. This phenomenon is called bronchoprotection and is severely impaired in asthmatic subjects. The ability of DIs to prevent a decrease in forced expiratory volume in 1 s (FEV1) was initially attributed to inhibition of airway narrowing. However, DIs taken before methach...

Using the recent experimental data on the left right asymmetry in fragmentation of transversely polarized quarks and the theoretical calculation of the proton transver-sity distribution in the effective chiral quark soliton model we explain the azimuthal asymmetries in semi-inclusive hadron production on longitudinally (HERMES) and transversely (SMC) polarized targets with no free parameters. O...

An overview of DIS 2003 is given with a focus on small-x physics and the interrelationship between deep inelastic scattering and heavy ion physics which furnishes much of the basic information for understanding highdensity QCD matter. In addition to small-x physics, topics covered include single spin asymmetries, light-cone gauge choices, strange quarks in the proton and non-global observables ...

Market power and allegations of market power abuse are perhaps the most contentious contemporary issues concerning electricity markets. A number of industry observers and participants have made allegations regarding the abuse of market power. While some of these allegations may be well-founded, many others may be nothing more than an attempt by some to retroactively correct for their own bad bu...
