Uso agrícola de composto de lixo: efeito do tempo de incubação solo/resíduo na disponibilidade de micronutrientes.

Visando dar uma solução para o problema do lixo urbano que foram coletados, analisados e interpretados teores dos micronutrientes Cu, Fe, Mg e Zn, em cinco tipos de solos, duas profundidades, utilizando-se quatro doses de composto de lixo (CL) e quatro períodos de incubação. Concluiu-se que o CL pode ser uma importante fonte de micronutrientes ao solo necessitando, no entanto, de legislação que regulamente seu uso adequado. Quanto a dinâmica dos micronutrientes no tempo foi dependente do tipo de solo, a profundidade só afetou os teores disponíveis, sendo os maiores valores observados nos solos Brunizem (B) e Terra Roxa Estruturada (TR).

Uso agrícola de composto de lixo: efeito do tempo de incubação solo/resíduo na disponibilidade de metal pesado.

O uso agrícola dos compostos de lixo (CL) urbano constitui a alternativa de maior visibilidade técnico-científica-econômica, pois estes são fontes de nutrientes e de matéria orgânica. Entretanto, é importante esclarecer que o uso do CL deve ser regulamentado, disciplinado e orientado tecnicamente por protocolos que definam a sua disposição final prevista em legislação, pois estes materiais podem conter metais pesados, que podem acumular-se nos alimentos e serem ingeridos pelo homem. Dentro desse contexto o trabalho buscou supror a deficiência de conhecimento relativo ao tempo que os metais pesados (Cádmio - Cd, Crômio - Cr, Cobalto- Co, Níquel - Ni e Chumbo - Pb), permanecem disponíveis nos solos após a adição do CL. A estração foi feita pelo método Mehlich-1, quando adicionado o CL incubado em cinco tipos de solos (Latossolo Vermelho-Amarelo, Podzólico Vermelho-Amarelo, Brunizem, planossolo e TerraRoxa Estruturada) de duas profundidades (0-20 e 20-40 cm), utilizando-se quatro doses de CL (0, 25, 50 e 100 t ha -1, em base úmida) e quatro períodos de incubação: 16, 32, 64 e 150 dias. A maioria dos metais pesados teve sua disponibilidade reduzida nos primeiros tempos de incubalção, sendo esse efeito dependente da textura, pH e teor de matéria orgânica do solo. Os dados relativos aos teores totais de metais pesados evidenciaram que o uso continuado de composto de lixo, principalmente nas doses mais elevadas, e em especial para o Cd, pode resultar riscos de contaminação do ambiente pelo efeito cumulativo.

Anglo-Irish relations in the framework of the EEC and Northern Ireland, 1969-1975

This thesis will analyse Anglo-Irish relations between 1969 and 1975, when two topics dominated the relationship: Northern Ireland and the entry of Britain and Ireland into the European Economic Community (hereafter EEC). In 1969 entry to the EEC was still only a possibility and awaited political developments, while the Northern Ireland problem had yet to escalate. 1975 on the other hand confirmed that Ireland would remain in the EEC even if Britain left while Direct Rule for Northern Ireland was confirmed as the British policy for the foreseeable future. These dates are significant because they encompass firstly pre and post entry to the EEC and how this transformed Anglo-Irish relations. Secondly they contain the commencement and then deterioration of the Northern Ireland problem and the attempts to resolve it that finally led to direct rule by Westminster. The study will examine the fluctuating nature of the relationship between Britain and Ireland. Special regard will be devoted to the demands of internal British politics and how such demands affected the relationship. Overall, the study will demonstrate how the bilateral relationship evolved under the pressure of events in Northern Ireland and adapted to the multilateral context of the EEC. It will compare the dynamics of the states’ interactions in two extremely different areas. The thesis will demonstrate how entry to the EEC transformed the unequal Anglo-Irish economic relationship and created one of partners within the EEC. It will also analyse how the developing Northern Ireland problem caused changes to British policy. In particular, it will examine how the British Government came to recognise the beneficial role that the Republic of Ireland might play in resolving the Troubles in Northern Ireland.

Stair na Gaeilge i gContae Thiobraid Árann 1700-1901

Stair na Gaeilge i gCo. Thiobraid Árann i rith na tréimhse 1700-1901 atá á ríomhadh sa tráchtas seo. Tar éis a cúlra agus a comhthéacs a shuíomh i gCaibidil a hAon, déantar scríobhaithe an cheantair a áireamh, fara tráchtaireacht orthu, i gCaibidil a Dó. I gCaibidlí a Trí agus a Ceathair, féachtar ar thionchar na hEaglaisí Caitlicí agus Eaglais na hÉireann (i measc eaglaisí Protastúnacha eile) ar an dteangain. I gCaibidil a Cúig, faightear spléachadh ar ghnéithe éagsúla de shaíocht an chontae, ag tabhairt léargais ar tháirgí na scríobhaithe, ar leabhair a clóbhualadh sa réigiún, agus ar fhilí móra na háite, leithéidí Liam Daill Uí Ifearnáin, ag sonrú limistéir faoi leith, an t-oirdheisceart, mar shampla. Léirítear éifeacht na gcumann Gaelach agus na ndíograiseoirí iomadúla a bhain leo. Ábhar suime, leis, feidhm na Gaeilge sna cúirteanna dlí. Tugtar faisnéis i gCaibidil a Sé ar fhianaise cuairteoirí ar an Ghaeilge mar urlabhra i dTiobraid Árann. Is anseo chomh maith a deintear anailís ar Dhaonáirimh na mblianta 1861-1901, le mórchuid adhmaid á baint as ceann 1901 go háirithe. Breactar as ainmneacha sagart agus múinteoirí le Gaeilge, agus tráchtar ar aicmí suntasacha eile, na póilíní agus na saighdiúirí a raibh an teanga sin ina mbéal acu. Tugtar le chéile dá réir na snáithíní difriúla eolais ar an dúiche ar bhealach nár tharla cheana don gcontae casta fairsing seo le haghaidh na tréimhse atá idir lámha ag an saothar.

Selected Solo Music for Saxophone by United States Composers: 1975-2005

This dissertation project identifies important works for solo saxophone by United States composers between 1975 and 2005. The quality, variety, expressiveness, and difficulty of the solo saxophone repertoire during these thirty years is remarkable and remedies, to some extent, the fact that the saxophone had been a largely neglected instrument in the realm of classical music. In twentieth-century music, including Jazz, the saxophone developed, nevertheless, a unique and significant voice as is evident in the saxophone repertoire that expands immensely in many instrumental settings, including the orchestra, solo works, and a wide variety of chamber ensembles. Historically, the saxophone in the United States first found its niche in Vaudeville, military bands, and jazz ensembles, while in Europe composers such as Debussy, D'Indy, Schmitt, Ibert, Glazounov, Heiden, and Desenclos recognized the potential of the instrument and wrote for it. The saxophone is well suited to the intimacy and unique timbral explorations of the solo literature, but only by the middle twentieth century did the repertoire allow the instrument to flourish into a virtuosic and expressive voice presented by successive generations of performers – Marcel Mule, Sigurd Rascher, Cecil Leeson, Jean-Marie Londeix, Fred Hemke, Eugene Rousseau, and Donald Sinta. The very high artistic level of theses soloists was inspiring and dozens of new compositions were commissioned. Through the 1960’s American composers such as Paul Creston, Leslie Bassett, Henry Cowell, Alec Wilder, and others produced eminent works for the saxophone, to be followed by an enormous output of quality compositions between 1975 and 2005. The works chosen for performance were selected from thousands of compositions between 1975 and 2005 researched for this project. The three recital dates were: April 6, 2005, in Gildenhorn Recital Hall, December 4, 2005, in Ulrich Recital Hall, and April 15, 2006, in Gildenhorn Recital Hall. Recordings of these recitals may be obtained in person or online from the Michelle Smith Performing Arts Library of the University of Maryland, College Park.
