Das valas comuns aos direitos humanos: a descoberta dos desaparecimentos forçados na Espanha contemporânea

Este texto se baseia numa investigação de campo “multissituada” de sete anos sobre o impacto do ciclo mais recente de exumações de fossas comuns da Guerra Civil espanhola, levada a termo em diversos cenários: exumações, atos comemorativos, conferências acadêmicas sobre a memória, apresentações de livros, concertos musicais, retiros universitários, assembléias, diversas ONG, grupos de trabalho com apoio institucional, laboratórios forenses, exposições de arte, manifestações, etc. Explora a forma pela qual os discursos e conceitos transnacionais dos direitos humanos tem se convertido paulatinamente em guias fundamentais da ação de muitas das associações que promovem o que se conhece como “recuperação da memória histórica, na medida em que o debate tem ido crescendo, se sofisticando, institucionalizando e, finalmente, indo a juízo. Neste sentido, a sequência de informações da Anistia Internacional sobre o processo ou o auto ditado por Baltasar Garzón aos 16 de setembro de 2008, a controvérsia gerada por ele até sua inibição aos 18 de novembro de 2008 e os sucessos derivados do processo que se lhe abriu no Supremo Tribunal, tem atuado como catalisadores desta irrupção dos direitos humanos nos debates sobre a memória, através de figuras jurídicas como as dos “crimes contra a humanidade”, os “desaparecimentos forçados”, e outras.Peer reviewe

Biomass Gasification: Fast Internal Circulating Fluidised Bed Gasifier Characterisation and Comparison

In 2004 the Department of Chemical and Process Engineering (CAPE) at University of Canterbury began a programme to investigate using biomass gasification integrated combined cycle (BIGCC) technology to convert waste products and residues to useful energy for the wood processing sector. This research was conducted as a part of Objective Two of the programme to develop gasification and gas cleaning technology. This project involved commissioning and characterising the operation of the Fast Internal Circulating Fluidised Bed (FICFB) gasifier and comparing its operation with a more conventional up-draught process owned and operated by Page Macrae in Mount Manganui. The wood derived gas composition of each gasifier was measured using gas chromatography and these compositions were used to calculate lower heating values (LHV). The CAPE FICFB gasifier has proven to produce successfully a gas with a lower heating value of 10400-12500 kJ/Nm³. The Page Macrae gasification process produces a low quality gas with a lower heating value of 4100-5100 kJ/Nm³. This is much lower than the CAPE gasifier since the oxidant used in the up-draught gasification process is air and the product gas is diluted by nitrogen. The Page Macrae gasification system combusts wood derived gas to produce steam for a laminar veneer lumber (LVL) processing plant so gas quality and heating value are less important than in electrical production applications. Reducing the nitrogen content of the CAPE product gas will increase the heating value of the gas. Improvements to the boiler system will reduce the amount of air required for gasification and hence reduce the nitrogen content. Further improvements to gas quality can be gained from a change in the fuel feed point from on top of the gasification column's bubbling fluidised bed to the side of the bubbling fluidised bed. The CAPE gasifier is much more complicated and requires specialised operators but produces a gas suitable for gas engine and gas turbine technology. Overall the CAPE gasification system is more suited to BIGCC applications than the Page Macrae process

Филлофаги древесных растений рода Ulmus в защитных насаждениях аридной зоны

Главными лесообразующими породами насаждений на урбанизированных территориях аридной зоны являются ильмовые (сем. Ulmaceae - более 70% всего дендросостава). Ухудшению их санитарного состояния активно способствуют листогрызущие вредители. Особой вредоносностью и регулярностью локальных очагов среди них отличаются Xanthogaleruca luteola (Müller, 1766), Cladius ulmi (Linnaeus, 1758) и Aproceros leucopoda (Takeuchi, 1939), последний- инвайдер. Деструктивное влияние этих вредителей на отдельные виды ильмовых неравнозначно.Elms are the main tree species of plantations in urban areas of the arid zone (Fam. Ulmaceae represents more than 70% of tree composition). Leaf-eating pests actively contribute to the deterioration of their sanitary condition.Xanthogaleruca luteola (Müller, 1766), Cladius ulmi (Linnaeus, 1758), and Aproceros leucopoda (Takeuchi, 1939) have a special harmfulness as well as the regularity of the local centers among all the pests. The last-mentioned species is invider. The destructive effect of those pests on certain types of elm plants are uneven

Potentiometric determination of cadmium with a solid composite electrode

The article presents the results of a study the possibility of potentiometric titration of the solution containing Cd (II) by the solution of sodium diethylditheocarbamate (DDTC-Na) using carbon composite electrode(CCE). The conditions for potentiometric determination of Cd (II) (working concentration range, pH, supporting electrolyte, working concentration range, frequency ultrasound).The titration curves were processed by the linearization method. This method is based on the transformation of the titration curve into a line of multiphase regression, whose parameters determine the equivalence point with high accuracy
