There are a number of microphysics and transport processes that can be extremely important to suppress or enhance the growth of these instabilities. I will provide a detailed description of how the hydrodynamic instability evolutions can be modified by incorporating the viscosity, surface tension, diffuse interface, and compressibility of the flows into the governing equations and growth rates.
This chapter examines Sweden’s emissions trends and the evolution of climate policy in an international perspective by focusing on its role and interdependent relationship with climate action in the EU and with international climate coalitions. The chapter examines the assumption that Sweden is a front-runner and role model in setting and implementing ambitious climate policy. The emission trends across sectors suggest that Sweden has been able to swiftly reduce its emissions, in particular from industry and energy conversion, but that current reduction rates are insufficient to reach its decarbonization target. Reducing emissions in agriculture and transport poses perhaps the greatest challenges for the Swedish state. The chapter also discusses the limits and possibilities for the State to implement its decarbonization target while being dependent on the climate policies in the EU, notably the Emission Trading Scheme (ETS). It also looks at Sweden’s role in international climate governance by zooming in on its role in international climate collaborations and clubs. Finally, the chapter provides three reasons for caution when it comes to Sweden’s reputation as a role model. First, that the rate of GHG reduction has declined significantly. Second, that consumption-based approaches to counting GHG emissions demonstrates that Sweden remains a high-emitting country. Third, that Sweden’s consumption-levels are far above the global average and its current consumption patterns should not be emulated by other countries.
The change in brand from British Railways to British Rail (BR) marked an important moment in the history of Britain’s railway. Running alongside BR’s modernization was a wider process of “professionalization” within the field of marketing. This paper explores how the wider professionalization of marketing impacted BR’s own marketing practices, showing that after 1965 BR opened its doors to new methods, means, and perhaps most importantly, specialists from outside the railway industry. Such marketing efforts helped to frame the railway in terms of individual travelers’ specific economic needs: by 1968 it had effectively segmented its passengers into demographic audiences, and by 1975, BR had a much better understanding of its markets. These individual economies were often highly gendered and saw only mixed success, but ultimately demonstrated an application of research, advertising, and promotion.
A handful of governments can rewrite the rules for the global car industry, doubling the pace of the transition to zero-emission vehicles and radically cutting the costs. The COP26 campaign woke some countries up to this opportunity, while some of the world’s largest carmakers continued to fight back.
Change in the economy, just as in the climate, can be self-reinforcing, sudden, and irreversible. The world’s fastest transitions to renewable energy and electric vehicles are happening in countries where economic tipping points have been crossed in these sectors. By deliberately targeting these thresholds, we can achieve large-scale change much more quickly than we might expect. To find these opportunities, we need to move away from traditional cost–benefit analysis and adopt a very different approach to decision-making.
Benthic macroalgae (including brown macroalgae or kelp) constitute one of the largest contributors to coastal primary production, but their ability to store and sequester carbon remains uncertain. Here, we use a numerical model of the flow/kelp interactions to study how tidal currents interact with an idealised numerical model of a giant kelp (Macrocystis pyrifera) forest, intending to better understand the potential for kelp growth in nutrient-limited conditions and the export of important tracers such as dissolved organic carbon. We calibrate and test our model using observations of currents within and surrounding a kelp forest in Southern California. By varying the density of kelp in our model, we find that there is a kelp density that maximises the export of tracer released from the kelp forest. Since the tracer advection/diffusion equation is linear with respect to the tracer concentration, the same kelp density corresponds to the maximum uptake for a tracer with a constant far-field concentration. The density at which this maximum occurs coincides with the density typical of natural kelp forests, where kelp growth may be limited by the uptake of dissolved nutrients from the surrounding water. Additionally, the drag induced on the tidal currents by the kelp forest results in a mean circulation through the kelp forest and a mean displacement of the kelp forest canopy.
This study provides researchers, practitioners, and policy makers with a profile of older adults’ travel behaviour and the older adult population that reports unmet travel needs. In addition, we quantified associations between reporting an unmet travel need and measures of health and social connectedness. Data came from the second follow-up survey of the Canadian Longitudinal Study on Aging, collected from 2018 to 2021 (n = 14,167). Nine in ten (90.2%) older adults aged 65 years and older indicated that driving is the main way they get around. Older adults with an unmet travel need were more likely to be women, have lower household incomes and education levels, and have a mobility limitation. People with an unmet travel need had 2.7 times the odds of reporting fair or poor general health (OR = 2.66, 95% CI: 2.19, 3.22) and 3.1 times the odds of feeling socially isolated (OR = 3.10, 95% CI: 2.57, 3.72) compared to those without an unmet need.
Varieties of kaolin, a rock, may be classified geologically, mineralogically, crystallographically, genetically, texturally, morphologically, by industrial use, and in other ways which are desired. In this paper, the first-order of classification used is geological, i.e., transported and residual, after which other categories are used as subdivisions.
Scan electron micrographs, SEM, of the textures of kaolin show that distinctive textures characterize the several categories of classification. Varieties in texture of kaolin include similarities to those typical of sedimentary, igneous and metamorphic rocks. Because word descriptions of the textures are inadequate in comparison to pictures of them, the reader is referred to the micrographs.
SEM's illustrate differences between kaolins which were transported, formed, or deposited from solution, a colloidal phase, or as orthodox clastic particles. The parent source of kaolin deposited, or “grown,” from solution may be difficult to ascertain. It is suggested that the total role of solution work in kaolin petrology can be more important than has ordinarily been credited.
In Chapter 13, we provide a preliminary analysis of the policy orientation of the EU’s post-Covid-19 new economic governance (NEG) regime to give policymakers, unionists, and social-movement activists an idea about possible future trajectories of EU governance of employment relations and public services. We do that on the basis of not only the recently adopted EU laws in these two policy areas, such as the decommodifying Minimum Wage Directive, but also EU executives’ post-Covid-19 NEG prescriptions in two areas (employment relations, public services), three public sectors (transport services, water services, healthcare services), and four countries (Germany, Italy, Ireland, Romania). Vertical NEG interventions in national wage policies paradoxically cleared the way for the decommodifying EU Minimum Wage Directive by effectively making wage policy an EU policymaking issue, but, in the area of public services, we see an accentuation of the trend of NEG prescriptions in recent years: more public investments but also much more private sector involvement in the delivery of public services.
Chapter 11 compares the policy orientation of the EU’s new economic governance (NEG) prescriptions in two policy areas (employment relations, public services), three sectors (transport, water, healthcare), four countries (Germany, Italy, Ireland, Romania) from 2009 to 2019. It reveals that almost all qualitative prescriptions pointed in a commodifying direction. Most quantitative prescriptions tasked governments to curtail wages and public expenditures too, but, over time, they not only became less coercive but also increasingly pointed in a decommodifying direction, tasking governments to invest more. It would, however, still be wrong to speak of a socialisation of NEG, not just given the decommodifying prescriptions’ weak coercive power but also because of their links to policy rationales that are compatible with NEG’s overarching commodification script. Moreover, Chapter 11 shows that NEG prescriptions tasked governments to channel more public resources into the allegedly more productive sectors (transport and water services) rather than into essential social services like healthcare. Given NEG’s country-specific methodology, it is not surprising that there have been only few instances of transnational action on specific NEG prescriptions. By contrast, the share of transnational labour protests targeting EU interventions broadly defined increased after 2008. This suggests that NEG has been altering protest landscapes.
The benefits of cycling are well-established, but how to engage people with bikes for active travel is far less understood. This study offers insights into the motivations, barriers, and design solutions associated with cycling. Interviews with 30 bike-share users in Glasgow, UK found a key motivation to be commuting time efficiency and the predominant barrier was shared space with vehicles. Alignment between the most mentioned design solution, dedicated cycling lanes, and the significant barrier of sharing space with vehicles underscores the importance of behavioural design interventions.
This chapter provides guidance on how to send specimens to a virology laboratory, including the need to provide full and accurate patient information, relevant clinical information, how to package and transport specimens and the need to send the correct specimens.
This chapter addresses the study of the technology in use in the Iberian Peninsula during the five final centuries of the Middle Ages, with special emphasis on the Christian kingdoms but not forgetting al-Andalus. First, agricultural techniques are considered, especially concerning irrigation agriculture. This is followed by the examination of other production sectors, including the sources of energy and the most significant technological innovations, as well as their routes of dissemination and social transference. The chapter ends with the exploration of both fluvial and maritime navigation techniques used in freight transport and the conclusions, which summarize some of the most relevant technological features of this period.
The roles of molecular structure and charge are examined in the transport of cations within montmorillonite clay films. The series of Ru(NH3)63+, Co(NH3)3+, Co(en)33+, Co(sep)3+ and Co(bpy)33+ are examined in detail via electrochemical and spectrochemical methods. The electrochemical signal is enhanced both in minimizing the time required to develop the signal and in the magnitude of the signal for Ru(NH3)63+. In addition, the potential for the observed reduction peak is shifted negative and the current peak associated with reduction disappears with rinsing of the clay film. These observations are characteristic of a compound that is held by simple electrostatic charge characteristics. In contrast, the compounds Co(NH3)3+, Co(en)33+ and Co(sep)3+, while showing rapid and enhanced signal development, eventually evolve a signal that is diminished with respect to the bare electrode, consistent with a hydrophobic mode of retention. The signal for Co(bpy)33+ is slow to be observed, is diminished with respect to the bare electrode and is shifted positive in potential, all hallmarks of a strong, non-electrostatic mode of binding within the clay.
This chapter, derived mainly from business-to-business serials such as The Bookseller[GK7], represents publishing in the 1860s as a collaborative enterprise comprising several interlocking systems. Basing its viewpoint in business-to-business texts shows that, unlike what is often suggested, it was not revolutionary. Instead, its use of technology and its distribution systems underwent a process of mainstreaming that intensified and refined extant methods of advertising, marketing, transport, wholesale, retail, and lending. Regulation was different, not because the various changes in the law offered anything new, but because details were modified in an attempt to improve them. Unlike many studies of publishing, this one engages with the regulation of labor relations, international distribution, and changing forms of business ownership as well as of the contents and ownership of texts through the laws of copyright, obscenity, and libel.
Natural clay-sized glauconite has the same mineralogical composition as sand-sized glauconite pellets but occurs in <2 μm clay fractions. This particular glauconite habit has been described previously from soil environments resulting from pelletal weathering but is rarely reported in higher-energy sedimentary environments. In the present study, clay-sized glauconite was identified as a common constituent in transgressive Neogene glauconite pellet-rich deposits of the southern North Sea in Belgium. X-ray diffraction results revealed that the characteristics of the clay-sized glauconite are very similar to the associated glauconite pellets in sand deposits. Both glauconite types consisted of two glauconite-smectite R1 phases with generally small percentages of expandable layers (<30%) with d060 values ranging between 1.513 Å and 1.519 Å. Clay-sized glauconite was not neoformed but formed by the disintegration of sand-sized glauconite pellets which were abraded or broken up during short-distance transport within the sedimentary basin or over the hinterland. Even in an environment where authigenic glauconite pellets occur, minimal transport over transgressive surfaces is sufficient to produce clay-sized glauconite. Furthermore, clay-sized glauconite can be eroded from marine deposits and subsequently resedimented in estuarine deposits. Clay-sized glauconite is, therefore, a proxy for the transport intensity of pelletal glauconite in energetic depositional environments and, moreover, indicates reworking in such deposits which lack pelletal glauconite.

Conservation, management and research require buffalo to be handled and sometimes moved from one place to another. Techniques providing more efficiency and a safer environment for buffalo capture and handling, including mass physical and individual chemical capture techniques, have been developed over the past few decades. These techniques, which are based on the experience and skills of staff, retain some room for improvement, e.g. using new drugs especially non-opioids for chemical immobilization, adapting technological advances (e.g. drone, scent technology) or new concepts (e.g. virtual boundary) to physical capture. The cardinal rule of buffalo or any wildlife capture, translocation and release is to regard all human interventions as potentially stressful to the animals, and therefore to strive to conduct them as far as possible as ‘short-term and low-stress management exercises’.
Reductions in the cost of transporting manufactured goods have been an important element in economic development in the recent past, and previous research suggests that the Roman period in Britain also saw substantial reductions in such costs. The authors investigate how far it is possible to measure changes in transport costs by considering the spatial distributions of pottery from known Roman production locations over time. Their analysis of an extensive database of pottery assemblages is designed to evaluate a series of expectations concerning how reductions in transport costs may have affected such assemblages and their distribution. Results suggest that costs were reduced by a factor of about two, leading to related changes in pottery production, distribution, and consumption over time. The ability to quantify changes in transport costs opens new perspectives for investigating the general determinants of economic development using archaeological data.
This chapter provides an overview of the key elements of turbulent flow. First, the basic averaging approach and examples of turbulent flow decompositions are discussed. Using these techniques, the average transport equations for mass, momentum, and species with closure models are given, followed by advanced numerical techniques for turbulent flows. Turbulent time and length scales as well as the kinetic energy cascade are overviewed, and theoretical turbulent species diffusion is treated.
Volume 2 of The Cambridge History of Global Migrations presents an authoritative overview of the various continuities and changes in migration and globalization from the 1800s to the present day. Despite revolutionary changes in communication technologies, the growing accessibility of long-distance travel, and globalization across major economies, the rise of nation-states empowered immigration regulation and bureaucratic capacities for enforcement that curtailed migration. One major theme worldwide across the post-1800 centuries was the differentiation between “skilled” and “unskilled” workers, often considered through a racialized lens; it emerged as the primary divide between greater rights of immigration and citizenship for the former, and confinement to temporary or unauthorized migrant status for the latter. Through thirty-one chapters, this volume further evaluates the long global history of migration; and it shows that despite the increased disciplinary systems, the primacy of migration remains and continues to shape political, economic, and social landscapes around the world.
