The PSHA map must be tested, since hypothesis testing is the heart of a scientific method, and it is inappropriate to adopt the map as the basis of seismic fortification in whole country without any test. Two paths of testing are suggested in this paper. The test result by counting up positive intensity difference shows that up to 2015 the percentages of total underestimation areas on 1990 and 2001 maps of China are equivalences of 5.6% and 6.0% in 50 years, both less than the exceeding probability 10% adopted in the map compiling procedure. The result of a case study of the common buildings with brick-concrete structure and frame structure in Sichuan region by evaluating the benefit of seismic fortification according to the two maps shows that the PSHA maps contribute benefits as economic loss reduction 67.9 and 79.7 billion RMB, death reduction 19439 and 17504 persons, and serious injury reduction 42632 and 37700 persons respectively during 2008 great Wenchuan Earthquake.

This chapter explains how abusive boilerplate could either be treated as a defective product, or else regulated under a new tort of intentional deprivation of basic legal rights. It argues that we should put boilerplate rights deletion schemes into the legal category—tort law—in which we can actually consider them as products, instead of considering them one at a time as a contract between two individuals. It also highlights boundary the fuzzy and shifting boundary between contracts and torts by focusing on doctrinal border areas such as fraud or misrepresentation, bad faith breach of contract, and warranty. A case study involving implied warranty of habitability in residential leases is presented. The chapter concludes with a comparison of tort and contract remedies, along with the common-law economic loss doctrine.

This paper makes a comparison between computer and hand computation of joint core area according to an example of typical engineering. Firstly, author summarized the common problems and erroneous judgments which are likely to happen in the software calculation of joint core in engineering design, and then analyzed the causes to these problems, and provided hand calculation solutions to related problems according to standard formulas. Author analyzed and proved that the reinforcement calculation of joint core area for frame structure calculation is not only necessary, but also can conveniently solve the coordination problems in the related terms of “Concrete Structure Design Norm”, “Earthquake Resistant Design Code” and “Concrete Structure Engineering Operation Standard”, and is also the supplement for the uncovered parts of computer calculation.

Abstract Schottky diodes are semiconductor switching devices with low forward voltage drops and very fast switching speeds. This paper provides an overview of the common failure modes in Schottky diodes and corresponding failure mechanisms associated with each failure mode. Results of material level evaluation on diodes and packages as well as manufacturing and assembly processes are analyzed to identify a set of possible failure sites with associated failure modes, mechanisms, and causes. A case study is then presented to illustrate the application of a systematic FMMEA methodology to the analysis of a specific failure in a Schottky diode package.

There has been a growing interest in the last decade in extracting information on Suspended Sediment Concentration (SSC) from acoustic backscatter in rivers. Quantitative techniques are not yet effective, but acoustic backscatter already provides qualitative information on suspended sediments. In particular, in the common case of a bi-modal sediment size distribution, corrected acoustic backscatter can be used to look for sand particles in suspension and provide spatial information on their distribution throughout a river crosssection. This paper presents a case-study where these techniques have been applied.

Wastewater and sewage sludge contain organic matter that can be valorized through conversion into energy and/or green chemicals. Moreover, resource recovery from these wastes has become the new focus of wastewater management, to develop more sustainable processes in a circular economy approach. The aim of this review was to analyze current sewage sludge management systems in Scandinavia with respect to resource recovery, in combination with other organic wastes. As anaerobic digestion (AD) was found to be the common sludge treatment approach in Scandinavia, different available organic municipal and industrial wastes were identified and compared, to evaluate the potential for expanding the resource recovery by anaerobic co-digestion. Additionally, a full-scale case study of co-digestion, as strategy for optimization of the anaerobic digestion treatment, was presented for each country, together with advanced biorefinery approaches to wastewater treatment and resource recovery.

AbstractLibel played an important and extraordinary role in early modern conflict culture. The article discusses their functions and the way they were assessed in court. The case study illustrates argumentative spaces and different levels of normative references in libel trials in 16th century electoral Saxony. In 1569, Andreas Langener – in consequence of a long stagnating private conflict – posted several libels against the nobleman Tham Pflugk in different public places in the city of Dresden. Consequently, he was arrested and charged with ‘libelling’. Depending on the reference to conflicting social and legal norms, he had therefore been either threatened with corporal punishment including his execution, or rewarded with laudations. In this case, the act of libelling could be seen as slander, but also as a service to the community, which Langener had informed about potentially harmful transgression of norms. While the common good was the highest maxim, different and sometimes conflicting legally protected interests had to be discussed. The situational decision depended on whether the articulated charges where true and relevant for the public, on the invective language, and especially on the quality and size of the public sphere reached by the libel.

In Italy, after the introduction of the Code of Cultural Heritage and Landscape in 2004, the Regional Landscape Plan (RLP) has acquired a coordination role in the urban planning system, for the implementation of policies for landscape protection and valorisation. The case study of the RLP of Sardinia is a paradigmatic application to the coastal area of the island, which is considered most vulnerable and subject to settlement pressure. The objectives of preservation and valorisation of the territorial resources should be transferred into local planning instruments by adopting strategies aimed at the preservation of the consolidated urban fabric, at the requalification and completion of the existing built-up areas according to the principles of land take limitation and increase in urban quality. The paper investigates the state of implementation and the level of integration of landscape contents in the local plans that have been adapted to the RLP, using a qualitative comparative method. In addition, the results of the plan coherence checks, elaborated by the regional monitoring bodies after the adaptation process, have been analysed to identify the common criticalities and weaknesses. The results highlight the lack of effectiveness of the RLP, after more than a decade since its approval, considering the limited number of adequate local plans and the poor quality of their analytical and regulative contents in terms of landscape protection and valorisation. Conclusions suggest some possible ways to revise the RLP, focusing on the participation of local communities and the development of a new landscape culture.

Abstract The property rights and the type of ownership (private owners, public domain and commons) are two fundamental concepts in relationship to the local development and to the social and environmental sustainability. Common forests were established in Europe since the Middle Ages, but over the centuries the importance of commons changed in parallel with economic and social changes. In recent decades, the scientific debate focused on the forest management efficiency and sustainability of this type of ownership in comparison to the public and private property. In Italy common forests have a long tradition with substantial differences in the result of historical evolution in various regions. In Sardinia region the private forests are 377.297 ha, the public forests are 201.324 ha, while around 120.000 ha are commons. The respect of the common rights changed in the different historical periods. Today, the common lands are managed directly by municipalities or indirectly through third parties, in both cases the involvement of members of community is very low. The main objective of the paper is to analyse forest management differences in public institutions with and without common property rights. To achieve the objective of the research the forest management preferences of community members and managers were evaluated and compared. The analysis was realized through the use of the principal-agent model and it has been tested in a case study in Sardinia region (Arci-Grighine district). The analysis of the results showed that the categories of actors considered (members of community, municipalities and managers) have a marked productive profile, but municipalities manage forests perceiving a moderate multifunctionality. Moreover, the representatives of the municipalities pay more attention to the interests of the collectivity in comparison to the external managers. They also attribute high importance to environmental and social forest functions.
