Pollen assemblages of modern soil samples from the Old Botanical Garden of the University of Göttingen

The importance of pollen analytical data for the reconstruction of the natural conditions and their changes caused by human impact in prehistorical and historical times is beyond all doubt. Pollen analysis can, however, be hampered by poor pollen preservation and low pollen concentrations. As an example pollen assemblages from excavation areas near Pompeii (see doi:10.1594/PANGAEA.777531) and from the Old Botanical Garden of the University of Göttingen are discussed. A pollen diagram (see doi:10.1594/PANGAEA.820590) from the site Höllerer See in Austria (N of the city of Salzburg) demonstrates the intensive agricultural influence on the vegetation of the area during Roman and Medieval times. Human influence was much weaker during the Iron and the Bronze ages. There is no indication of human impact on the vegetation during the Migration period.

Fabrication of luminescent nanostructures by electron-beam direct writing of PMMA resist

We report on the conversion of non-luminescent conventional poly(methylmethacrylate) (PMMA)-based electron-beam resists into luminescent materials when used as negative-tone resists, that is, when exposed to high electron irradiation doses. Raman spectroscopy reveals the chemical transformation induced by electron irradiation which is responsible for the observed luminescence in the visible (blue) region. The emission intensity from exposed PMMA-based patterns can be controlled by the electron irradiation dose employed to create them.

Microfabrication processes for microfluidic devices on a single laser Workstation: direct writing lithography on SU-8, laser ablation on polymers and mask manufacturing

We demonstrate the capability of a laser micromachining workstation for cost-effective manufacturing of a variety of microfluidic devices, including SU-8 microchannels on silicon wafers and 3D complex structures made on polyimide Kapton® or poly carbonate (PC). The workstation combines a KrF excimer laser at 248 nm and a Nd3+:YVO4 DPSS with a frequency tripled at 355 nm with a lens magnification 10X, both lasers working at a pulsed regime with nanoseconds (ns) pulse duration. Workstation also includes a high-resolution motorized XYZ-tilt axis (~ 1 um / axis) and a Through The Lens (TTL) imaging system for a high accurate positioning over a 120 x 120 mm working area. We have surveyed different fabrication techniques: direct writing lithography,mask manufacturing for contact lithography and polymer laser ablation for complex 3D devices, achieving width channels down to 13μ m on 50μ m SU-8 thickness using direct writing lithography, and width channels of 40 μm for polyimide on SiO2 plate. Finally, we have tested the use of some devices for capillary chips measuring the flow speed for liquids with different viscosities. As a result, we have characterized the presence of liquid in the channel by interferometric microscopy.

Air Mines. Urban Space Station

Air Mines The sky over the city's port was the color of a faulty screen, only partly lit up. As the silhouette of nearby buildings became darker, but more clearly visible against the fading blur-filter of a background, the realization came about how persistent a change had been taking place. Slowly, old wooden water reservoirs and rattling HVAC systems stopped being the only inhabitants of roofs. Slightly trembling, milkish jellyfish-translucent air volumes had joined the show in multiples. A few years ago artists and architects seized upon the death of buildings as their life-saving media. Equipped with constructive atlases and instruments they started disemboweling their subjects, poking about their systems, dumping out on the street the battered ugliness of their embarrassing bits and pieces, so rightly hidden by facades and height from everyday view. But, would you believe it? Even ?old ladies?, investment bankers or small children failed to get upset. Of course, old ladies are not what they used to be. It was old ladies themselves that made it happen after years of fights with the town hall, imaginative proposals and factual arguments. An industry with little financial gains but lots of welcome externalities was not, in fact, the ground for investment bankers. But they too had to admit that having otherwise stately buildings make fine particulate pencils with their facades was not the worse that could happen. Yes, making soot pencils had been found an interesting and visible end product of the endeavor, a sort of mining the air for vintage writing tools one can actually touch. The new view from the street did not seem as solid or dignified as that of old, and they hated that the market for Fine Particulates Extraction (FPE, read efpee) had to be applied on a matrix of blocks and streets that prevented undue concentration of the best or worse solutions. It had to be an evenly distributed city policy in order for the city to apply for cleaning casino money. Once the first prototypes had been deployed in buildings siding Garden Avenue or Bulwark Street even fast movers appreciated the sidekick of flower and plant smell dripping down the Urban Space Stations (USS, read use; USSs, read uses) as air and walls cooled off for a few hours after sunset. Enough. It was all nice to remember, but it was now time to go up and start the lightweight afternoon maintenance of their USS. Coop discussions had taken place all through the planning and continued through the construction phase as to how maintenance was going to be organized. Fasters had voted for a pro, pay a small amount and let them use it for rent and produce. In the end some neighbors decided they were slow enough to take care and it was now the turn. Regret came periodically, sometimes a week before, and lasted until work actually started. But lately it had been replaced by anxiety when it needed to be passed over to the next caretaker. It did not look their shift was good enough and couldn?t wait to fix it. Today small preparations needed to be made for a class visit next day from a nearby cook school. They were frequenters. It had not been easy, but it shouldn?t have been that hard. In the end, even the easiest things are hard if they involve a city, buildings and neighbors. On the face of the data, the technicalities and the way final designs had been worked out for adaptation to the different settings, the decision of where to go was self evident, but organization issues and the ever-growing politics of taste in a city of already-gentrified-rodents almost put the project in the frozen orbit of timeless beautiful future possibilities. This is how it was. A series of designs by XClinic and OSS had made it possible to adapt to different building structures, leave in most cases the roof untouched and adapted a new technology of flexing fiberglass tubes that dissipated wind pressure in smooth bending.......

Teaching writing through reading: a text-centred approach

Se comparan y contrastan las destrezas requeridas para la comprensión lectora con aquellas que se necesitan para la producción de escritos correctos, en inglés, coherentes y bien cohesionados. Se comentan las actividades didácticas relacionadas con ello.The aim of this article is to establish the relevance of teaching reading and writing skills to students at Madrid Polytechnic University, and to show the relationship and interdependence of these activities in EAP courses. The skills involved in reading and writing processes for academic purposes for L2 students are compared and commented on from a rhetorical point of view. Learning tasks based on text-type analysis are recommended as adequate activities to build schemata for writing and represent a synthesis of the teaching objectives proposed for reading and writing English courses.

A “REVOLTA” DE JEÚ E A ESTELA DE DÃ: Um Estudo Em 2 Reis 10,28-36

A pesquisa tem por objetivo trabalhar o evento da Revolta de Jeú, em conjunto com a Estela de Dã, tendo como ponto de partida para tal, a exegese da perícope de 2 Reis 10-28,36. A história Deuteronomista apresenta o ato da Revolta de Jeú como sendo um feito demasiadamente importante, na restauração do culto a Javé em Israel, a partir de um contexto onde o culto a outras divindades, em Israel Norte, estava em pleno curso. No entanto, a partir da análise conjunta da Estela de Dã, que tem como provável autor o rei Hazael de Damasco, somos desafiados a ler esta história pelas entrelinhas não contempladas pelo texto, que apontam para uma participação ativa de Hazael, nos desfechos referentes a Revolta de Jeú, como sendo o responsável direto que proporcionou a subida de Jeú ao trono em Israel, clarificando desta forma este importante período na história Bíblica. Para tal análise, observar-se-á três distintos tópicos, ligados diretamente ao tema proposto: (1) A Revolta de Jeú e a Redação Deuteronomista, a partir do estudo exegético da perícope de 2 Reis 10,28-36, onde estão descritas informações pontuais sobre período em que Jeú reinou em Israel; (2) Jeú e a Estela de Dã, a partir da apresentação e análise do conteúdo da Estela de Dã, tratando diretamente dos desdobramentos da guerra em Ramote de Gileade, de onde se dá o ponto de partida à Revolta de Jeú; e por fim (3) O Império da Síria, onde a partir da continuidade da análise do conteúdo da Estela de Dã, demonstraremos a significância deste reino, além de apontamentos diretamente ligados ao reinado de Hazael, personagem mui relevante no evento da Revolta de Jeú.
