Circular economy (CE) is an economic model, in which raw materials remain in circulation as long as possible and the generation of waste is minimized. In the fertilizer sector, waste rich in nutrients should be directed to agriculture purposes. This paper presents an analysis of recommended directions for the use of nutrient-rich waste in fertilizer sector and an evaluation of possible interest in this kind of fertilizer by a selected group of end-users (nurseries). The scope of research includes the state-of-the-art analysis on circular aspects and recommended directions in the CE implementation in the fertilizer sector (with focus on sewage-based waste), and survey analysis on the potential interest of nurseries in the use of waste-based fertilizers in Poland. There are more and more recommendations for the use of waste for agriculture purposes at European and national levels. The waste-based products have to meet certain requirements in order to put such products on the marker. Nurserymen are interested in contributing to the process of transformation towards the CE model in Poland; however, they are not fully convinced due to a lack of experience in the use of waste-based products and a lack of social acceptance and health risk in this regard. Further actions to build the social acceptance of waste-based fertilizers, and the education of end-users themselves in their application is required.

<p>This paper describes the key elements from early planning to completion of a new bridge over the River Barrow which is part of the New Ross bypass in the south of Ireland. The structure has a total length of 887m, with a span arrangement of 36-45-95-230-230-95-70-50-36m. The two central twin spans are the longest of its kind in the world (extrados with a full concrete deck). The bridge carries a dual carriageway with a cable arrangement consisting of a single plane of cables located in the central axis of the deck. The design and construction focused in providing a structure with long term durability, resilience, and a robust approach to design scenarios using the Eurocodes and state of the art analysis techniques, including extreme events such as fire and ship impact<i>.</i></p>

In a previous article I sought to appraise the field of Turkish studies, for the most part among western (predominantly American) scholars (MESA Bulletin, Vol. 3, No. 3, October 15, 1969). To fill out the picture, it is appropriate to also view the state of social research among the rapidly growing body of Turkish teachers and researchers. This article is not, however, a direct parallel to others in the MESA “State of the Art” series, in that it is not basically bibliographical. Such a review would require far more time, space, and knowledge in depth of several other social science disciplines than is currently available to me, because despite the remarks made below about problems of definition, the quantity and technical sophistication of work by Turkish researchers is quite large and is growing rapidly. Furthermore, since most of the research referred to below is in Turkish, the number of persons to whom a bibliographic review might be useful is quite limited. Instead, I think it would be more interesting to MESA members and other American social scientists to examine the characteristics and problems of what is probably one of the most vigorous social science communities in the “developing” countries, with a view (among other things) to helping facilitate increased cooperation between Turkish and American scholars in our common endeavors of advancing the state of knowledge.
