Neste trabalho, procuro associar as análises teóricas dentro do Programa Minimalista para as construções com SE ao seu comportamento ao longo do tempo nos dados do Corpus Tycho Brahe, em comparação com o comportamento dos sujeitos ao longo do tempo (séculos XVI a XIX). As diferenças que aparecem nos padrões estatísticos de argumentos pré-verbais, pós-verbais e nulos permitiram corroborar análises teóricas que consideram tais construções ativas e não passivas. Além disso, procuro contribuir para o entendimento da mudança linguística que ocorre do SE como um morfema passivo para o SE como um argumento, e proponho uma análise teórica para as construções com SE que dê conta do comportamento estatístico dos dados associando a proposta de Raposo e Uriagereka (1996) sobre a motivação de um núcleo F(orce) com a de D’Alessandro (2003) sobre a maneira como o objeto checa Caso nominativo.

The measurement of broadband ultrasonic attenuation (BUA) in cancellous bone at the calcaneus was first described in 1984. The assessment of osteoporosis by BUA has recently been recognized by Universities UK, within its EurekaUK book, as being one of the “100 discoveries and developments in UK Universities that have changed the world” over the past 50 years, covering the whole academic spectrum from the arts and humanities to science and technology. Indeed, BUA technique has been clinically validated and is utilized worldwide, with at least seven commercial systems providing calcaneal BUA measurement. However, a fundamental understanding of the dependence of BUA upon the material and structural properties of cancellous bone is still lacking. This review aims to provide a science- and technology-orientated perspective on the application of BUA to the medical disease of osteoporosis.

The mixed anion mineral parnauite Cu9[(OH)10|SO4|(AsO4)2].7H2O has been studied by Raman spectroscopy. Characteristic bands associated with arsenate, sulphate, hydroxyl units are identified. Broad bands are observed and are resolved into component bands. Two intense bands at 859 and 830 cm-1 are assigned to the 1 (AsO4)3- symmetric stretching and 3 (AsO4)3- antisymmetric stretching modes. The comparatively sharp band at 976 cm-1 is assigned to the ν1 (SO4)2- symmetric stretching mode and a broad spectral profile centered upon 1097 cm-1 is attributed to the ν3 (SO4)2- antisymmetric stretching mode. A comparison of the Raman spectra is made with other arsenate bearing minerals such as carminite, clinotyrolite, kankite, tilasite and pharmacosiderite.

In the UK, Singapore, Canada, New Zealand and Australia, as in many other jurisdictions, charity law is rooted in the common law and anchored on the Statute of Charitable Uses 1601. The Pemsel classification of charitable purposes was uniformly accepted, and together with a shared and growing pool of judicial precedents, aided by the ‘spirit and intendment’ rule, has subsequently allowed the law to develop along much the same lines. In recent years, all the above jurisdictions have embarked on law reform processes designed to strengthen regulatory processes and to statutorily define and encode common law concepts. The reform outcomes are now to be found in a batch of national charity statutes which reflect interesting differences in the extent to which their respective governments have been prepared to balance the modernising of charitable purposes and other common law concepts alongside the customary concern to tighten the regulatory framework.

For the first time since 1601, a number of leading common law nations have almost simultaneously chosen to revise and place on the statute books the law relating to charity. The Politics of Charity examines the reasons for this and for the varying legislative outcomes. ----- ----- ----- This book examines the legal framework and political significance of charity, as developed within England & Wales, contrasts this with the experiences of other common law nations and explores the resulting implications for government/sector relationships in those countries. It suggests that charity law lies at the heart of the relationship between government and the non profit sector, that there is an unmistakeable political agenda driving charity law reform and that the differential in legislative outcomes reflects important differences in the policies pursued by the governments concerned.----- ----- ----- Looking at fundamentally different approaches of government towards the sector in the UK, Ireland, the US, New Zealand, Canada, Singapore and Australia, O’Halloran argues the results will have implications for the present workings of parliamentary democracy.----- ----- ----- The Politics of Charity will be a valuable resource for academics, regulators and legal practitioners as well as advanced and postgraduate students in law, politics and public policy.

In a study aimed at better understanding how students adapt to new blended studio learning environments, all undergraduate and masters of architecture students at a large school of architecture in Australia, learned a semester of architectural design in newly renovated, technology embedded, design studio environments. The renovations addressed the lessons learned from a 2011 pilot study of a second year architectural design studio learned in a high technology embedded prototype digital laboratory. The new design studios were purpose designed for the architecture students and adapted Student-Centred Active Learning Environment for Undergraduate Programs design principles. At the end of the semester, the students completed a questionnaire about their experiences of learning in the new design studio environments. Using a dual method qualitative approach, the questionnaire data were coded and extrapolated using both thematic analysis and grounded theory methodology. The results from these two approaches were compared, contrasted and finally merged, to reveal five distinct emerging themes, which were instrumental in offering resistance or influencing adaptation to, the new blended studio learning environments. This paper reports on the study, discusses the major contributors to resistance and adaptation, and proposes points for consideration when renovating or designing new blended studio learning environments. This research extends the 2011 pilot study by the same authors: ‘Dichotomy in the design studio: Adapting to new blended learning environments’.

The optimum parameters for synthesis of zeolite NaA based on metakaolin were investigated according to results of cation exchange capacity and static water adsorption of all synthesis products and selected X-ray diffraction (XRD). Magnetic zeolite NaA was synthesized by adding Fe3O4 in the precursor of zeolite. Zeolite NaA and magnetic zeolite NaA were characterized with scanning electron microscopy (SEM) and XRD. Magnetic zeolite NaA with different Fe3O4 loadings was prepared and used for removal of heavy metals (Cu2+, Pb2+). The results show the optimum parameters for synthesis zeolite NaA are SiO2/Al2O3 = 2.3, Na2O/SiO2 = 1.4, H2O/Na2O = 50, crystallization time 8 h, crystallization temperature 95 �C. The addition of Fe3O4 makes the NaA zeolite with good magnetic susceptibility and good magnetic stability regardless of the Fe3O4 loading, confirming the considerable separation efficiency. Additionally, Fe3O4 loading had a little effect on removal of heavy metal by magnetic zeolite, however, the adsorption capacity still reaches 2.3 mmol g�1 for Cu2+, Pb2+ with a removal efficiency of over 95% in spite of 4.7% Fe3O4 loading. This indicates magnetic zeolite can be used to remove metal heavy at least Cu2+, Pb2+ from water with metallic contaminants and can be separated easily after a magnetic process.

The mineral weloganite Na2Sr3Zr(CO3)6·3H2O has been studied by using vibrational spectroscopy and a comparison is made with the spectra of weloganite with other carbonate minerals. Weloganite is member of the mckelveyite group that includes donnayite-(Y) and mckelveyite-(Y). The Raman spectrum of weloganite is characterized by an intense band at 1082 cm−1 with shoulder bands at 1061 and 1073 cm−1, attributed to the View the MathML source symmetric stretching vibration. The observation of three symmetric stretching vibrations is very unusual. The position of View the MathML source symmetric stretching vibration varies with mineral composition. The Raman bands at 1350, 1371, 1385, 1417, 1526, 1546, and 1563 cm−1 are assigned to the ν3 (CO3)2− antisymmetric stretching mode. The observation of additional Raman bands for the ν3 modes for weloganite is significant in that it shows distortion of the carbonate anion in the mineral structure. The Raman band observed at 870 cm−1 is assigned to the (CO3)2− ν2 bending mode. Raman bands observed for weloganite at 679, 682, 696, 728, 736, 749, and 762 cm−1 are assigned to the (CO3)2− ν4 bending modes. A comparison of the vibrational spectra is made with that of the rare earth carbonates decrespignyite, bastnasite, hydroxybastnasite, parisite, and northupite.

MapReduce is a computation model for processing large data sets in parallel on large clusters of machines, in a reliable, fault-tolerant manner. A MapReduce computation is broken down into a number of map tasks and reduce tasks, which are performed by so called mappers and reducers, respectively. The placement of the mappers and reducers on the machines directly affects the performance and cost of the MapReduce computation. From the computational point of view, the mappers/reducers placement problem is a generation of the classical bin packing problem, which is NPcomplete. Thus, in this paper we propose a new grouping genetic algorithm for the mappers/reducers placement problem in cloud computing. Compared with the original one, our grouping genetic algorithm uses an innovative coding scheme and also eliminates the inversion operator which is an essential operator in the original grouping genetic algorithm. The new grouping genetic algorithm is evaluated by experiments and the experimental results show that it is much more efficient than four popular algorithms for the problem, including the original grouping genetic algorithm.
