Floresta e sociedade: um percurso (1875-2005)

Este texto procurou relacionar os diferentes intervenientes na floresta portuguesa ⎯ os seus proprietários privados e comunitários e ainda o Estado ⎯ com as funções que esperavam dessa mesma floresta ⎯ articulação com os sistemas agrários, produtiva, de lazer e recreio, ambiente e de conservação, simbólica ⎯ e com o resultado global, que foi o aumento da área florestal, a qual, admite-se, pode ter passado de uns 7% a aproximadamente um terço da área do continente português, entre 1875 e 2005. Ao longo do tempo considerado, a relação entre intervenientes, funções esperadas e ampliação da floresta variou, o que levou a delimitar três períodos, 1875-1938, 1938-1974, 1974-2005. Assim, o enorme acréscimo da área de floresta no primeiro destes períodos foi impulsionado pelos particulares que tinham em vista as produções florestais. Nos períodos que se seguiram, a área continuou a crescer, embora de forma mais moderada, pesando então a acção do Estado. Este, no primeiro período, assumiu sobretudo a função de conservação e protecção do território juntando-se seguidamente aos particulares em torno da floresta produtiva. No terceiro dos períodos, a função ambiental passaria a ser exigida pela sociedade e pelos acordos europeus. A função lazer afirma-se igualmente no tempo mais recente, captando então o interesse dos proprietários privados. Como apoio aos sistemas agrários, a floresta foi importante até aos anos sessenta, declinando no seguimento

Combined population dynamics and entropy modelling supports patient stratification in chronic myeloid leukemia

Modelling the parameters of multistep carcinogenesis is key for a better understanding of cancer progression, biomarker identification and the design of individualized therapies. Using chronic myeloid leukemia (CML) as a paradigm for hierarchical disease evolution we show that combined population dynamic modelling and CML patient biopsy genomic analysis enables patient stratification at unprecedented resolution. Linking CD34+ similarity as a disease progression marker to patientderived gene expression entropy separated established CML progression stages and uncovered additional heterogeneity within disease stages. Importantly, our patient data informed model enables quantitative approximation of individual patients’ disease history within chronic phase (CP) and significantly separates “early” from “late” CP. Our findings provide a novel rationale for personalized and genome-informed disease progression risk assessment that is independent and complementary to conventional measures of CML disease burden and prognosis

Studi Kandungan Bahan Organik Dan Mineral (N, P, K, Fe Dan Mg) Sedimen Di Kawasan Mangrove Desa Bedono, Kecamatan Sayung, Kabupaten Demak

Mangroves in Bedono Village, District Sayung, Demak Regency considered as degraded mainly due to land conversion and reclamation which lead to coastal erosion and permanent flooding. This mangroves condition, in conjuction with the exsistance of several estuaries believes in some part controlled sedimentation and related process in the area including sediment particle size, organic and mineral (N, P, K,Fe and Mg) distribution. The study was aimed to determine distribution of organic and mineral (N, P, K,Fe and Mg) of mangrove sediment in Bedono Village, District Sayung, Demak Regency, and conducted between May-July 2010. A purposive sampling base descriptive method was applied for this study, and sediment samples were analysed at Geological Laboratory (Marine Science Department) Faculty of Fisheries and Marine Sciences and Chemical Analytical Laboratory (Chemical Department), Faculty of Science and Mathematics, Diponegoro University. The result showed that sediment organic content of Tunjung Sari (15,42%) and Gonjol (16,46%) were slightly higer than in Sayung (12,48%) and Soban (12,06%), N content in Tunjung Sari (0,46%) and Soban (0,43%) much higher than in Gonjol (0,27%) and Sayung (0,29%), while P content in Gonjol (354,73 mg/kg) was the highest followed by Tunjung Sari (245,60 mg/kg) and Sayung (203,43 mg/kg) and the lowest was in Soban (80,42 mg/kg). The rate of sediment K content, similar to N content, was high in Tunjung Sari (0,50%) and Soban (0,54%) and lower in Gonjol (0,39%) and Sayung (0,35%). Fe content was higher in Gonjol (5,52 %) than in Tunjung Sari (3,93 %), Sayung (2,55 %) and Soban (3,92 %), meanwhile Mg content was higher in Tunjung Sari (0,125 %) than Gonjol (0,075 %), Sayung (0,080 %) and Soban (0,006 %)

Documentary photography/postmodern commodities

This honours project is divided into two parts. Part one is the written thesis. Part two is the photographic component. Part one discusses some of the practices and discourses associated with \u27documentary\u27 photography. Some documentary practices and discourses of the past can be seen to be culturally divisive. These practices and discourses were based on being, white, male and European. This ideology and its discursive modes are in conflict with contemporary photographic practices and the relevant social and cultural theories that define it. The thesis defines the discourses and practices of the modernist and postmodernist documentary photographer. It highlights the discursive modes and locates a common link. In the consumerist postmodern world, the image, whether it is modernist or postmodernist becomes a commodity. Part two is a photographic book called \u27roses\u27. The book component works with the notion of the \u27commodity\u27, forming a link with the written thesis
