By autonomously navigating the water's surface, Sea swarm proposes a new system for ocean-skimming andoil removal. Sea swarm uses a photovoltaic-powered conveyor belt made of a thin nanowire mesh to propel itself and collect oil. The nanomaterial, patented at MIT, can absorb up to 20 timesits weightin oil. The flexible conveyor beltsoftly rolls over the ocean'ssurface, absorbing oil while deflecting water because of its hydrophobic properties Sea swarm is meant to figure as a fleet, or “swarm” of vehicles, which communicate their location through GPS and Wi-Fi so as to make an organized system for collection that can work continuously without human support. Sea swarm works by detecting the sting of a spill and moving inward until it's removed the oilfromone site before joining other vehicles that are still cleaning. The fleet uses cuttingedge nanotechnology to unravel current environmental problems while envisioning long-term solutions for the longer term. With a replacement design strategy, we will revive and preserve the standard of our oceans.

In this article I discuss some of the theoretical implications of adopting moral economy as an approach to analysing new forms of flexible production and work. Despite a growing interest in the anthropology of precarity and work, the linkages between political and moral economies have been relatively neglected. By discussing E.P. Thompson’s approach to moral economy as well as ways moral economy has been discussed in anthropology, the article argues it is a timely and encompassing approach for the study of flexible work and precarity, as well as compliance and resistance to inequality. A nexus of diverse moral frameworks of value converge at the production site and back home, contributing to the reproduction of precarity and capital under flexible forms of accumulation. The article suggests that moral economy may offer an encompassing approach to studying individual ideas and practices and their relation with collective moral frameworks and confinements and to exploring change and change potential. It draws from an ethnography based on long-term fieldwork in a privatized factory in Bulgaria, in the context of radical economic transformations and privatization projects. It scrutinizes solidarities, tensions and inequalities developed around the conveyor belt, with a particular focus on gender and employment status inequalities and their intertwinement with managerial and household practices.

The article reveals innovative experience in the study of projective technologies in the training of primary school teachers in the general education system. In the practical part of the study, relevance of training primary school teachers to the use of wide opportunities in teaching children on the basis of new system values that orient themselves to a self-developing pupil who is able to flexibly use changing component life activities at a new level is substantiated. It also actualizes the need to study and use the experience of foreign countries, taking into account the specifics of domestic realities, and to make a comparative analysis of the theory, methodology and organization of future primary school teachers training in the context of modernization of the education system in the Republic of Kazakhstan. The primary education system is recognized as one of the most important priorities of the long-term Strategy «Kazakhstan – 2050».

Soil degradation caused by erosion is one of the biggest environmental problems. The Geographic Information System (GIS) QGIS and ArcGIS were used to prepare thematic maps. The average slope resulted in smooth wavy (42.1%), flat (27.8%), and wavy to strong wavy (19.9%) over the entire length of the sub-basin. Erodibility resulted in very high (41%) mainly in sectors with a predominance of Neossolos Quartzarênicos soils, on average (7.1%) in the South and Southwest and low (51.1%) of the area corresponding to the soil of the type Dystrophic Yellow Latosol. The expansion of the agribusiness associated with inadequate soil management in areas susceptible to erosion at BHRG can compromise long-term environmental, social, and economic sustainability. It is important develop suitable agricultural techniques appropriate to the soil to optimize its use and its sustainable production capacity.

Tomographic Analysis

This paper is dedicated to investigating the properties of smooth conveyor belts through a tensile loading test, with the aim of examining the behavior of the inner structure of the belt samples. When the belt is subjected to a long-term strain, the belt relaxation effect is observed and changes may occur to the inner structure of the belt. The tensile test at constant velocity determines the load strength limit of the strip samples. The experiment has also shown the phenomenon of relaxation of the samples after the load. Metro-tomographic analysis is used to observe the behavior of the internal structure of the belt sample after the load. The obtained results indicate the initial damage of the inner structure of the conveyor belt occurred at the value of 2157 N. Under this load, the maximum damage size was 4.8 mm. This confirms the suitability of the method for tracking changes in the internal structure.

Global Biogeochemical Cycles

<p>Despite being major players on the global biogeochemical cycles, microorganisms are generally not included in holistic views of Earth’s system. The Microbial Conveyor Belt is a conceptual framework that represents a recurrent and cyclical flux of microorganisms across the globe, connecting distant ecosystems and Earth compartments. This long-range dispersion of microorganisms directly influences the microbial biogeography, the global cycling of inorganic and organic matter, and thus the Earth system’s functioning and long-term resilience. Planetary-scale human impacts disrupting the natural flux of microorganisms pose a major threat to the Microbial Conveyor Belt, thus compromising microbial ecosystem services. Perturbations that modify the natural dispersion of microorganisms are, for example, the modification of the intensity/direction of air fluxes and ocean currents due to climate change, the vanishing of certain dispersion vectors (e.g., species extinction or drying rivers) or the introduction of new ones (e.g., microplastics, wildfires). Transdisciplinary approaches are needed to disentangle the Microbial Conveyor Belt, its major threats and their consequences for Earth´s system resilience.</p>

New System

Prison construction was among the most important infrastructural changes brought about by British rule in nineteenth-century India. Informed by the extension of liberal political philosophy into the colony, the development of the British colonial prison introduced India to a radically new system of punishment based on long-term incarceration. Unlike prisons in Europe and the United States, where moral reform was cited as the primary objective of incarceration, prisons in colonial India focused on confinement as a way of separating and classifying criminal types in order to stabilize colonial categories of difference. In Imperial Vision, Colonial Prisons: British Jails in Bengal, 1823–73, Mira Rai Waits explores nineteenth-century colonial jail plans from India's Bengal Presidency. Although colonial reformers eventually arrived at a model of prison architecture that resembled Euro-American precedents, the built form and functional arrangements of these places reflected a singularly colonial model of operation.

New System

In 1996 he Nevada Department of Motor Vehicles and Public Safety launched the Genesis project, a technology-enabled reengineering endeavor. In September of 1999, after four years of planning, organizational restructuring and system development, the new system was released. To the accompaniment of great publicity, it fell dramatically short of expectations. This case provides the background necessary to understand the origins and shortcomings of the system, then focuses on the turn-around effort that took the system to a point of successful operation within a year of its going into production. The turn around was accomplished under great pressure to retreat to the legacy system. The effort involved a synergy of manual and technical corrections to bring overall system performance to acceptable levels. The DMV now faces the formidable challenge of taking full responsibility for the long-term maintenance of a system that was designed and implemented by outside contractors.
