Protective Lung Ventilation

Zinc poisoning has been reported from many parts of the world. It is one of the global health problems that affect many organs, if exposed by inhalation of zinc vapors or by consumption of contaminated food and water. Long term exposure to zinc compounds from different sources such as air, water, soil, and food, lead to toxic effects on body systems, especially digestive, respiratory, and nerve systems, and also causes cancer. Zinc levels can be determined in blood, urine, hair, and nails. Patients with zinc toxicity need chelating agents, other pharmacological treatment, protective lung ventilation, extracorporeal membrane oxygenation (ECMO), and supportive care.

<p>Wetlands are ecosystems recognized as one of the most valuable natural resources in the world. Although this importance, several wetlands around the world have lost areas due to anthropic threats. One example of a wetland with international importance is the Taim Wetland. This Ramsar Site number 2298, is a fresh-water wetland with 330 km<sup>2</sup> located in the Southern part of Brazil, close to the border with Uruguay. The primary threat to this wetland is related to water demand conflicts on its watershed. Extensive rice fields occur around Taim Wetland and large yearly volumes of water from its main tributary Mangueira Lake are withdrawn, leading to changes in the hydrodynamics within the wetland. Thus, by one side, there is the regional economic dependence of rice cultivation and, on the other hand, conditions related to water availability are vital for maintaining the ecosystem as a whole. Different human-made infrastructures also impact local hydrodynamics as road, gates, fauna tunnels, natural effects as backwater and climate factors. Due to its importance, the Taim Wetland has been the object of different studies aiming to evaluate strategies for an integrated water management policy, allowing it to reach both environmental and economic benefits. The local complexity leads to the need for applying hydrological-hydrodynamic models able to represent the behavior accurately. Paz, 2003 and Villanueva, 1997 already applied hydrological and 2D-hydrodynamic modeling in the area; however, in the light of information available at that time and computational constraints, these studies needed to adopt several simplifications. In this study, the 2D HEC-RAS 5.0.7 was used to represent the system based on new terrain information obtained from the combination of different sources such as satellite, drone images and local measurement allowing the acquisition of information such as flooding areas, velocities, and flow patterns. New insights of local features such as internal channels, lakes, dunes, road and vegetation such as emergent macrophytes permitted new understandings of hydrodynamics. Nevertheless, hydraulic structures as a set of gates and fauna tunnels were also included in the representation, allowing the analysis of different operational scenarios during the modeling. These results also provide critical information for the environmental evaluation of habitats and points towards better management policies.</p>

Capitalist World

Predominant analyses of energy offer insufficient theoretical and political-economic insight into the persistence of coal and other fossil fuels. The dominant narrative of coal powering the Industrial Revolution, and Great Britain's world dominance in the nineteenth century giving way to a U.S.- and oil-dominated twentieth century, is marred by teleological assumptions. The key assumption that a complete energy “transition” will occur leads some to conceive of a renewable-energy-dominated twenty-first century led by China. After critiquing the teleological assumptions of modernization, ecological modernization, energetics, and even world-systems analysis of energy “transition,” this paper offers a world-systems perspective on the “raw” materialism of coal. Examining the material characteristics of coal and the unequal structure of the world-economy, the paper uses long-term data from governmental and private sources to reveal the lack of transition as new sources of energy are added. The increases in coal consumption in China and India as they have ascended in the capitalist world-economy have more than offset the leveling-off and decline in some core nations. A true global peak and decline (let alone full substitution) in energy generally and coal specifically has never happened. The future need not repeat the past, but technical, policy, and movement approaches will not get far without addressing the structural imperatives of capitalist growth and the uneven power structures and processes of long-term change of the world-system.

In The Body in Pain, Elaine Scarry analyzes the structure of torture as an unmaking of the world in which the tools that ought to support a person’s embodied capacities are used as weapons to break them down. The Security Housing Unit (SHU) of California’s Pelican Bay State Prison functions as a weaponized architecture of torture in precisely this sense; but in recent years, prisoners in the Pelican Bay Short Corridor have re-purposed this weaponized architecture as a tool for remaking the world through collective resistance. This resistance took the form of a hunger strike in which prisoners exposed themselves to the possibility of biological death in order to contest the social and civil death of solitary confinement. By collectively refusing food, and by articulating the meaning and motivation of this refusal in articles, interviews, artwork, and legal documents, prisoners reclaimed and expanded their perceptual, cognitive, and expressive capacities for world-making, even in a space of systematic torture.

Social Consideration

There is a culture of disengagement from social consideration in engineering disciplines. This means that first year engineering students, who arrive planning to change the world through engineering, lose this passion as they progress through the engineering curriculum. The community driven technology innovation and investment program described in this paper is an attempt to reverse this trend by fusing community engagement with the normal engineering design process. This approach differs from existing project or trip based approaches – outreach – because the focus is on local communities with which the university team forms a long-term partnership through weekly in-person meetings and community driven problem statements – engagement.

This study represents part of a long-term research program to investigate the influence of U.K. accountants on the development of professional accountancy in other parts of the world. It examines the impact of a small group of Scottish chartered accountants who emigrated to the U.S. in the late 1800s and early 1900s. Set against a general theory of emigration, the study's main results reveal the significant involvement of this group in the founding and development of U.S. accountancy. The influence is predominantly with respect to public accountancy and its main institutional organizations. Several of the individuals achieved considerable eminence in U.S. public accountancy.

Mobile devices play a growing role in the everyday lives of children around the world, prompting important questions about their effects on childhood experiences. Exploring the recent global trends in children’s use of smartphone devices, the authors examine the reconfiguring of children’s communicative practices and cultures of connectivity, documenting the opportunities and risks that smartphone technology affords. Throughout the chapter the authors challenge the notion of “digital childhoods,” drawing on the most reliable research on children and smartphones including findings from Global Kids Online, which suggest that digital divides intersect with existing social inequalities, exacerbating the barriers for less privileged children. This raises further questions about the long-term consequences for children’s development, rights, and future access to opportunities and resources.

Complicated Nature

The economy of Southeast Asia has been in relatively good shape in spite of the instability of the world monetary system, trade deficits, and the worldwide oil crisis. There are promising factors for economic growth, opportunities for employment, and possibilities of rising income. But Asian development presents short-and long-term problems of a very complicated nature. One of the most serious problems is inflation and its impact on the social and political programs of individual countries. At the same time, there are severe shortages of basic commodities, such as oil and food. My own country, Japan, is among those affected.
