Nuclear Power Production

Discussions on environmental implications of nuclear energy have so far been concentrated on radiological aspects: disposal of radioactive wastes, safety of nuclear power production, safe handling of plutonium, and problems associated with uranium mining. There are, however, several environmental issues associated with nuclear power production that are non-radiological in nature: thermal pollution and attendant effects on aquatic life, problems associated with land-use requirements, aesthetic considerations, habitat alterations, and atmospheric effects. These different non-radiological environmental implications of nuclear energy are reviewed.The paper concludes that, while there are some environmental problems which exist at present, and a few more could emerge in the future, all these problems appear to be solvable with the present state of technological development. The extent of environmental degradation can be significantly reduced by appropriate design and planning.

Conceptual Revolution

Biomedical imaging represents a practical and conceptual revolution in the applied sciences of the last thirty years. Two basic ingredients permitted such a breakthrough: the technological development of hardware for the collection of detailed information on the organ under investigation in a less and less invasive fashion; the formulation and application of sophisticated mathematical tools for signal processing within a methodological setting of truly interdisciplinary flavor. A typical acquisition procedure in biomedical imaging requires the probing of the biological tissue by means of some emitted, reflected or transmitted radiation. Then a mathematical model describing the image formation process is introduced and computational methods for the numerical solution of the model equations are formulated. Finally, methods based on or inspired by Artificial Intelligence (AI) frameworks like machine learning are applied to the reconstructed images in order to extract clinically helpful information. Important issues in this research activity are the intrinsic numerical instability of the reconstruction problem, the convergence properties and the computational complexity of the image processing algorithms. Such issues will be discussed in the following with the help of several examples of notable significance in the biomedical practice.

When University R&D institutions perform projects to create technology solutions, they produce knowledge and learn. The basic idea proposed in this article is that one of the fuels that produce such a dynamic process is the organization’s knowledge energy. When it flows in multidisciplinary projects within and outside an organization's borders, it also produces recurrent learning along each technology prototype improvement. Through the years this dynamic is capable of producing substantial transformations and empower R&D institutions, as we found in the transformation of the Applied Sciences and Technological Development Center into the Applied Sciences and Technology Institute of the National Autonomous University in México. This is a limited case study.

Natural Component

In the context of current problems of sustainable development of the modern city, the issues of present and future of coastal areas occupy a key place. In large cities there is a shortage of the natural component of the coastal zone environment, while the priority is given to transport infrastructure, which leads to environmental degradation and deprives the coastal strip recreational use. For many coastal territories the main problems remain: expansion of transport infrastructure; intensive process of urbanization and building up of coastal territories; loss of natural components and landscape identity of coastal strips and water areas. In Moscow, these problems are complemented by the monotony and typical character of the architectural design of coastal areas. Integrated development of the environment of coastal zones can be realized by various methods, created on the principles of a balanced infrastructure. The formation of urban and landscape directions and their relationship.

The article proves that a systematic approach to the urban organization of coastal areas includes complex environmental and recreational tasks. The study examines in detail the need to create a comprehensive strategy for the restoration of the coastal zone. The complex of measures is substantiated, among which the activation of water protection functions of coastal areas, rehabilitation of disturbed territories, use of recreational and town-planning potential of coastal territories for formation of recreational base along water area, development of integrated system of management of processes of coastal zones and integration of ecosystems. The work separately highlights the possibility of creating a recreational cluster that will ensure the continuity of the natural framework, given the multi-vector formation of the urban environment. It is established, that the connection of the recreational cluster with the suburban green strip and water area will create a pedestrian recreational corridor in the city and beyond, as well as contribute to the greening of the city and influence the modeling of ecological infrastructure.

The sale of fish is one of the main roles that is very important, in addition to getting the optimal price, the sale of fish is also very supportive of the economy of the region, especially the coast. In the sale of fish today still need a technological development in the field of calculation. The amount of fish and consumer demand makes fish sellers or fishermen unable to properly control the results of their sales, starting from service and pricing, calculation errors that cause prices to be not optimal, causing losses. Therefore, a solution is needed that can overcome these problems. TOTOKAN (Fish Pond Shop) is an innovation to prevent errors in the calculation of the selling price of fish using Arduino Uno-based RFID and LCD as its monitor. TOTAKAN is designed with an RFID system that has been programmed by ARDUINO UNO R3 which is a source of microproseor from all systems, while the 4x4 keypad serves as a calculation of the number of fish purchases as well as the overall price, and a 16x2 LCD serves to display the price and the number of copies. TOTAKAN is able to be the main solution for the regional economy, especially coastal areas. In addition to simple, this innovation can also create efficiency over time, so that the seller does not need to control the maximum sales results.

Temperature Estimation

Seawater temperature is an extremely important factor as it affects the ecological balance of marines ecosystems, the continental weather, and the earth's atmosphere. However, the pressure on both coastal and marine resources, the use of oceans as a wastes deposit, the increase of urbanization, and anthropogenic activities in coastal zones are all causes of thermal pollution. The degradation of water quality by any process that changes ambient water temperature constitutes a significant danger in many coastal areas in the world. The region of Tangier-Ksar Sghir overlooking the Mediterranean Sea is experiencing growth of population and increasing urbanization and human activities, in addition to the industrial and touristic activities along the coastline. These activities are the main sources of thermal pollution that have effects on human health and the environment in the region. So, it is very important to examine seawater temperature in order to protect the marine and coastal areas from thermal pollution. In the current study, an approach based on TIRS thermal band data was used to estimate sea surface temperature. The results showed a good correlation between in-situ measurements and the estimated values from Landsat8 images along the coastline of the study area.
