Baltic winter 42 seconds ethereal sweeping and haunting with female vocals

Baltic Winter Shorts 03 - a Slavic mermaid rests upon a rock on the edge of the Baltic Sea. It is night time during the depths of winter. She risks not being able to return to the sea as it could freeze in the time that she drapes the snow crested pine trees with her ethereal calls. Her voice travels through the Medieval forest in search of her nymph . . . will he hear her? Or will her calls only serve to sing her loneliness?

OK . . . now for the technical . . . I wrote this with a documentary in mind. I have used a sampled Finnish/Estonian Kantele, a touch of an acoustic guitar, female vocals, percussion, and a couple of synths.

Os discursos preventivos sobre o uso de drogas e as potencialidades dos educadores na prevenção primária: relato de uma experiência

Este estudo objetiva definir as potencialidades dos educadores na prevenção primária do uso e do abuso de drogas, llcitas e ilicitas. Na primeira parte deste texto, foram analisados alguns manuais destinados a prevençao nas Escolas do nosso pais, selecionados e classificados de acordo com os diferentes discursos, neles contidos, quanto ao uso de drogas e quanto ã atuação dos educadores na prevenção primária. Na segunda parte, procedeu-se ao relato de uma experiência particular de prevençao primária, desenvolvida num municlpio do estado do Rio de Janeiro, durante o ano de 1988, realizada com educadores da região. Durante esta experiência, procurou-se construir uma visão critica sobre o uso de drogas, sobre os diferentes nlveis de consumo e sobre o momento sóciocultural no qual se dá esta prática. Do ponto de vista metodológico, bu~ cou-se apoio na pedagogia psicanalitica, resgatando experiências quotidianas na construção de um saber coletivo, definido como a prevenção que aqueles educadores desejavam desenvolver. Utilizou-se, tambem, tecnicas de mo bilização e de integração, atraves das quais, processos de projeção e introjeção puderam resultar numa elaboração interna das questões relativas ao uso e abuso de drogas. A análise dos manuais e da experiência particular de prevenção primária relatada, apontou alguns caminhos: propostas preventivas autoritárias devem ser definitivamente superadas; propostas preventivas que privilegiem a escuta da demanda de orientação e de ajuda, por parte dos alunos usuários de drogas, que admitam a discussão sobre a estrutura geradora do consumo de drogas, que incorporem a necessidade de prazer e se liberem das imposições do poder constituido, têm possibilidades de contribuir para a diminuição dos problemas decorrentes do abuso de drogas; as práticas dos educadores na prevenção primária do uso e do abuso de drogas terão mais chances na medida em que houver um processo de "desintoxicação" da própria sociedade.

Money distribution with intermediation

This pap er analyzes the distribution of money holdings in a commo dity money search-based mo del with intermediation. Intro ducing heterogeneity of costs to the Kiyotaki e Wright ( 1989 ) mo del, Cavalcanti e Puzzello ( 2010) gives rise to a non-degenerated distribution of money. We extend further this mo del intro ducing intermediation in the trading pro cess. We show that the distribution of money matters for savings decisions. This gives rises to a xed p oint problem for the saving function that di cults nding the optimal solution. Through some examples, we show that this friction shrinks the distribution of money. In contrast to the Cavalcanti e Puzzello ( 2010 ) mo del, the optimal solution may not present the entire surplus going to the consumer. At the end of the pap er, we present a strong result, for a su cient large numb er of intermediaries the distribution of money is degenerated.

Electrical scanning probe microscopy on organic optoelectronic structures

In the field of organic optoelectronics, the nanoscale structure of the materials has huge im-pact on the device performance. Here, scanning force microscopy (SFM) techniques become increasingly important. In addition to topographic information, various surface properties can be recorded on a nanometer length scale, such as electrical conductivity (conductive scanning force microscopy, C-SFM) and surface potential (Kelvin probe force microscopy, KPFM).rnrnIn the context of this work, the electrical SFM modes were applied to study the interplay be-tween morphology and electrical properties in hybrid optoelectronic structures, developed in the group of Prof. J. Gutmann (MPI-P Mainz). In particular, I investigated the working prin-ciple of a novel integrated electron blocking layer system. A structure of electrically conduct-ing pathways along crystalline TiO2 particles in an insulating matrix of a polymer derived ceramic was found and insulating defect structures could be identified. In order to get insights into the internal structure of a device I investigated a working hybrid solar cell by preparing a cross cut with focused ion beam polishing. With C-SFM, the functional layers could be identified and the charge transport properties of the novel active layer composite material could be studied. rnrnIn C-SFM, soft surfaces can be permanently damaged by (i) tip induced forces, (ii) high elec-tric fields and (iii) high current densities close to the SFM-tip. Thus, an alternative operation based on torsion mode topography imaging in combination with current mapping was intro-duced. In torsion mode, the SFM-tip vibrates laterally and in close proximity to the sample surface. Thus, an electrical contact between tip and sample can be established. In a series of reference experiments on standard surfaces, the working mechanism of scanning conductive torsion mode microscopy (SCTMM) was investigated. Moreover, I studied samples covered with free standing semiconducting polymer nano-pillars that were developed in the group of Dr. P. Theato (University Mainz). The application of SCTMM allowed non-destructive imag-ing of the flexible surface at high resolution while measuring the conductance on individual pillarsrnrnIn order to study light induced electrical effects on the level of single nanostructures, a new SFM setup was built. It is equipped with a laser sample illumination and placed in inert at-mosphere. With this photoelectric SFM, I investigated the light induced response in function-alized nanorods that were developed in the group of Prof. R. Zentel (University Mainz). A block-copolymer containing an anchor block and dye moiety and a semiconducting conju-gated polymer moiety was synthesized and covalently bound to ZnO nanorods. This system forms an electron donor/acceptor interface and can thus be seen as a model system of a solar cell on the nanoscale. With a KPFM study on the illuminated samples, the light induced charge separation between the nanorod and the polymeric corona could not only be visualized, but also quantified.rnrnThe results demonstrate that electrical scanning force microscopy can study fundamental processes in nanostructures and give invaluable feedback to the synthetic chemists for the optimization of functional nanomaterials.rn
