This thesis examines the effects on vegetation at selected sites in northern South Australia of excluding various herbivores over a four and a half year period and of two intense but controlled grazing pulses over a six month period followed by an 18 month recovery period in a dune-swale land system. These changes are compared with changes recorded over an 11-year period at the Olympic Dam mine site. It found that short-term changes in vegetation revealed by ordination of periodical cover, density and species richness, are attributable to the periodicity of rainfall and that, under present grazing regimes, rainfall effects override grazing effects. Differences between the effects of sheep and cattle hoof damage are worthy of further investigation, as is the impact of kangaroo grazing. These two factors may have important implications for the management of Australian rangelands.

At most sites annual grass abundance was positively correlated with rainfall, soil moisture after rainfall and higher soil productivity. Perennial grass abundance was negatively correlated with annual grass abundance and soil moisture after rainfall, and was weakly positively correlated with percentage summer rainfall, elevation, radiation, gravel and slope. Overall perennial grasses responded little to the environmental variables investigated, but strongly to annual grass abundance, while for annual grasses soil moisture was the driving variable. / Thesis (Ph.D.)--University of Adelaide, School of Earth and Environmental Sciences, Discipline of Environmental Biology, 2004

In the North there is a large consumption of fruit pulp of açaí, with an accumulation of waste without proper management. This residue causes harm to public health and environmental disturbances. In this work we developed panels with fiber from the seed of açaí (Euterpe Precatória ) from the physical, chemical and mechanical fiber. The research was divided into two stages, which was the morphological characterization, chemical of the physical and mechanical analysis fiber açaí, and then the panels were fabricated and therewere made tests of the panels. The principle was made a preliminary panel to set the level of fiber and resin, from the results of static bending, this was produced 6 (six) fiber panels with adhesive based on castor oil and polyurethane resin derived from petroleum. According to NBR 148103, assays were performed in static bending, tensile and screw perpendicular to the surface. The results were satisfactory, with values above the norm NBR 148103, meeting the technical requirements for construction and furniture industry / O açaí é fruto do açaizeiro, uma palmeira natural da Amazônia brasileira, encontrada próximo dos igarapés. Na região Norte existe um grande consumo da polpa do fruto do açaí, com um acúmulo de resíduo sem manejo adequado. Este resíduo provoca malefícios para a saúde pública e transtornos ambientais. No presente trabalho foram desenvolvidos painéis com a fibra da semente do açaí (Euterpe Precatória ), a partir da caracterização morfológica, física, química e mecânica da fibra. A pesquisa foi dividida em duas etapas, no qual foi feita a caracterização morfológica, análise química, análise física e mecânica da fibra do açaí, e em seguida foram confeccionados os painéis e feitos os ensaios dos painéis. A princípio foi feito um painel preliminar para definir o teor de fibra e de resina, a partir do resultado do ensaio de flexão estática, deste foram produzidos 07 (sete) painéis de fibra, com adesivo a base de mamona e resina poliuretana derivada de petróleo. De acordo com a norma NBR 148103, foram realizados os ensaios de flexão estática, tração perpendicular e arrancamento de parafuso de superfície. Os resultados obtidos foram satisfatórios, com valores acima da norma NBR 148103, atendendo requisitos técnicos da construção civil e para a indústria moveleira

Pagrindinis darbo tikslas yra išanalizuoti Europos Sąjungos šiaurinio regiono, akcentuojant Rusijos Federacijos ir Norvegijos Karalystės įtaką regione, vaidmenį, užtikrinant energetinį saugumą Europos Sąjungoje, bei numatyti galimas ES energetikos politikos perspektyvas netolimoje ateityje. Siekiant geriau atskleisti darbo tikslą, keliami šie uždaviniai: apibrėžti saugumo sąvokos pagrindines dimensijas, veiksnius bei regioninio saugumo komplekso svarbą ir reikšmę Europos Sąjungos kontekste; atskleisti Europos Sąjungos šiaurinio ir Arkties regionų vaidmenį ES energetikos politikoje; išanalizuoti dabartinę ES energetinę padėtį ir priklausomybę nuo energetinių išteklių importo; išsiaiškinti Rusijos Federacijos ir Norvegijos Karalystės vietą ES energetinio saugumo kontekste; numatyti ES kaip galimo energetinio saugumo komplekso energetikos politikos ateities gaires. Parašius darbą pavyko patvirtinti iškeltą ginamąjį teiginį, jog nacionalinių valstybių kova dėl energetinių išteklių ir individualūs sprendimai sudaro sąlygas energetiniam nesaugumui Europos Sąjungoje, kadangi ES deklaruojamas siekis kalbėti „vienu balsu“ ir įgyvendinti bendrą energetinę politiką, prasilenkia su valstybių nacionaliniais interesais ir lieka neįgyvendintas. Nors Europos Sąjunga gali būti laikoma energetiniu saugumo kompleksu, kuriame energetinės priklausomybės santykis tarp šalių yra suvokiamas kaip grėsmė (kurios šaltinis iš esmės yra vienas – Rusijos Federacija), tačiau didėjantis vartojimas ir...

The North region is analyzed emphasizing two countries which are main energy suppliers for Europe – Russian Federation and Norway. For a better understanding of the object, the specific proposition has been formulated: the struggle of the national states for energy resources and individual decisions allow energy insecurity in the European Union since the EU’s declared objective „to speak in one voice“ is inconsistent with national interests of EU’s member states. Although the European Union can be defined as the complex of energy security in which the relation of dependence is comprehended as a threat (the main source of this threat is the Russian Federation’s energy monopoly), however the growing consumption and competition for energy resources encourage the countries to search for alternative energy resources and its suppliers. These actions disrupt the initiatives of the common European Union’s energy policy. The political consciousness is not yet grown in the EU’s countries and it determinates the weakness of the EU as a political construct in case of competition with the rising economical powers (such as India and China) for energy resources. On the other hand the consumption is growing in the Russian market as well, which implies possible insecurity of supply... [to full text]

The physical characterization of the fruits showed fruits weighting between 118,17 to 503,26 g, with length and diameter very similar one to another, attributing the fruits a round, ovoid or subglobose shape and average pulp yield of 18,556%, higher than previous reported yields. Total soluble solids, total soluble sugars and reducing sugars contents presented excellent values, besides low contents of phenolic compounds in all the fractions, what characterizes the bacuri pulp as little astringent, denoting potential nor only to “in natura” consumption as also to industry processing. Bacuri fruits must not be considered a good source of Vitamin C. High contents of total and soluble pectins were found in the genotypes M5, M7, M16, M22 and M23, these being the more appropriate to the obtaining of jam or fruit-in-syrup, crystallized fruit and paste sweet.

A caracterização física dos frutos mostrou frutos com peso variando entre 118,17 a 503,26 g, com características de comprimento e diâmetro muito próximos dando aos frutos do bacurizeiro formas redondas, ovóides ou subglobosa e rendimento de polpa médio de 18,556%, superior a rendimentos relatados anteriormente. Em relação aos teores de sólidos solúveis totais, açúcares solúveis totais e açúcares redutores estes apresentaram ótimos índices, além de baixos teores de compostos fenólicos em todas as frações caracterizando a polpa de bacuri como pouco adstringente, demonstrando potencial tanto para consumo in natura como para processamento industrial. Os frutos do bacurizeiro não podem ser considerados uma boa fonte de vitamina C. Altos teores de pectina total e solúvel foram encontrados nos genótipos M5, M7,M16, M22 e M23, sendo estes os melhores para a obtenção de geléias, compotas, frutas glaceadas, frutas cristalizadas e doces em pasta. A polpa de bacuri é uma excelente fonte de minerais, destacam-se os teores de cálcio, magnésio, sódio, potássio, fósforo, ferro e zinco.

The analysis approaches the ways in which this capital has been injected in these agricultural industries’ productive dynamics and what have been the spatial dynamics linked to this capital flow. In order to achieve the objective we have focused on this region’s most important productive chains and on agricultural industries that have received financial support from BNDES during the years of 2000 to 2016, focusing on large companies, but also analyzing smaller industries. The theoretical construction was structured over Milton Santos’ conceptual category of Socio-spatial Formation for the understanding of the genesis and the development of agricultural industries from the North region, along with Ignácio Rangel’s theoretical contributions, through the Brazilian Economic Basic Duality, as well as the author’s approaches on economic cycles. The results point to productive forces intense dynamics and productive relations of agricultural industries that have received BNDES’ financial support during the correspondent period, allowing new spatial dynamics and broadening these companies’ increased capital reproduction movement. In relation to the North region of Paraná state, capital flows coming from the financial institution have allowed switches mainly on the rural credit profile within the micro-regions of Ibaiti and Wenceslau Braz, as well as on the production elevation and dynamics of orange, corn, chicken, and coffee productive chains, in addition to the amplification of direct and indirect jobs, along with this region’s more effective insertion within the productive circuit of the industrial sector. / A presente pesquisa analisa a dinâmica espacial das agroindústrias da Mesorregião Norte Pioneiro do Paraná e o papel dos financiamentos via BNDES nesse processo. Desta forma, são abordadas as formas de como esse capital foi inserido na dinâmica produtiva dessas agroindústrias e quais foram as dinâmicas espaciais vinculadas a esses fluxos de capital. Para tal objetivo focamos nas cadeias produtivas mais importantes dessa região e também nas agroindústrias que realizaram operações de financiamento junto ao BNDES durante os anos de 2000 a 2016, priorizando as empresas de maior porte, mas utilizando também nas análises as agroindústrias menores. A construção teórica foi estruturada principalmente a partir da utilização da categoria de Formação Sócio-espacial desenvolvida por Milton Santos, para o entendimento da gênese e desenvolvimento das agroindústrias do Norte Pioneiro, juntamente com as contribuições teóricas de Ignácio Rangel, através da Dualidade básica da economia brasileira, acrescidos dos aportes teóricos vinculados aos ciclos da economia, propostos por este autor. Desta forma, os resultados da pesquisa apontam para uma intensa dinamização das forças produtivas e relações de produção das agroindústrias que utilizaram os fluxos de capitais do BNDES durante o referido período, possibilitando novas dinâmicas espaciais, ampliando o movimento de reprodução ampliada do capital nessas empresas. No que se refere a Mesorregião Norte Pioneiro, esses fluxos de capitais desta instituição financeira proporcionaram principalmente alterações no perfil do crédito rural nas Microrregiões de Ibaiti e Wenceslau Braz, elevação da produção e dinamização das cadeias produtivas da laranja, milho, frango, café, ampliação dos empregos diretos e indiretos, juntamente com a inserção mais efetiva desta região no circuito produtivo do setor industrial.
