An important goal for the building sector is to produce buildings with a minimum of environmental impact. Recycling can considerably reduce these impacts. An aim is therefore to produce new buildings with a minimum of environmental impact during their lifetime and with a high recycling potential. This paper presents a suggestion for assessing the recycling potential. The recycling potential can be

Background: Flat and depressed colorectal tumours are common in Japan but are very rare or non-existent in Western countries. Aims: To study the occurrence of flat colorectal tumours in a southern Swedish population. Methods: In this prospective study, 371 consecutive European patients were examined by high resolution video colonoscopy combined with chromoendoscopy. The nature of the lesions was

This paper describes a project course that focuses on all the different stages in an ASIC design flow. The project starts at algorithm level, followed by architecture selection, netlist generation, down to physical layout, fabrication, and finally verification. The scope of the project, implementing a complete MP3 decoder in VHDL and sending it for fabrication, motivates the students to work hard

In this paper the entropy of the joint distributions of vertex degrees and vertex degree frequencies of random hypertrees and in particular random trees are studied. Due to the relationship between random hypertrees and random allocations of particles into cells, the entropy of occupancy distributions in the case where the number of particles does not exceed the number of urns is also established.

It is considered self-evident that chemical interactions are a component of competition in terrestrial systems, but they are largely unknown in aquatic systems. In this review, we propose that chemical interactions, specifically allelopathy, are an important part of phytoplankton competition. Allelopathy, as defined here, applies only to the inhibitory effects of secondary metabolites produced by

Alkali metal adsorption on metals is studied by High Resolution Core Level Spectroscopy (HRCLS) and Low Energy Electron Diffraction (LEED). The studies can be divided into two parts: adsorption of alkali multilayers and alkali adsorption in the submonolayer regime. In the case of the adsorption of alkali multilayers, the interface region between a thin alkali film of Na,K,Rb and Cs on different s

This book chapter introduces the reader to an anthology of reportage, essays, eulogies, poems, proclamations, drawings, photographs, letters and more from the most chaotic phase of China’s Cultural Revolution. Entitled A Heroes’ Register, it is one of no more than a handful of surviving self-documenting accounts by the ‘dictating masses’ themselves of the ‘dictatorship of the masses’, as the Maois

Popular Abstract in English The eye is a complex device in charge of producing clear and sharp images of the outside world. While some people need glasses early on in their lives, others have nearly perfect vision until, all of a sudden, they have to hold books or documents further and further away from their eyes to be able to read them and eventually have to resort to reading glasses. This visuaHealthy eye lenses are transparent and flexible, able to adapt shape in order to focus on far away and close-by objects. With age, however, this flexibility is lost, leading to a condition known as presbyopia. This vision disorder where close-by objects appear blurred commonly starts around the age of 40. The aim of this thesis is to elucidate the molecular origin of the gradual hardening of the c

The potential of using security systems for adding value to business bears similarities to the capacity that Data Warehouse and Data Mining offers. Reviewing the literature on documented factors for successful data warehouse adoption and implementation points in the direction of where the future possibilities and challenges lies in adoption and implementation of “value adding” security systems. Th

This paper provides a systemic analysis of complex dynamic issues associated with resource use, scarcity and efficiency by applying systems thinking with respect to sustainability criteria. Casual loop diagramming methodology is adopted to create a conceptual model to better understand the interconnected patterns, cause effect relations and feedbacks between the three dynamic complex systems that

In 2014, more than 200,000 refugees and migrants fled for safety across the Mediterranean Sea. Crammed into overcrowded, unsafe boats, thousands drowned, prompting the Pope to warn that the sea was becoming a mass graveyard. The early months of 2015 saw no respite. In April alone more than 1,300 people drowned. This led to a large public outcry to increase rescue operations. Throughout this period

There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. Regional sediment transport and shoreline evolution models that fully include important coastal processes at local scale are lacking at present. The ov

The research history and conditions in experimental archaeology up until today show a heavy emphasis on technological studies within a hypothetical-deductive theoretical paradigm. How is it possible to enhance the conditions for experimental archaeology so that it can also develop as a humanistic area of research, more closely related to existential perspectives of human life? We argue for the int
