Brakująca część historii (literatury). O książce Marty Baron-Milian Wat plus VAT

The missing part of (literary) historyThe article is a review of Marta Baron-Milian’s Wat plus VAT, the first monograph about connections between economy and literature in Aleksander Wat’s work. The author tries to show Baron’s book as a part of wider phenomenon, which can be observed after the great crisis in 2008, as a result of returning of different humanistic approaches to the problems of capitalist economy. By analyzing “economic consciousnessˮ and literary strategies of Aleksander Wat (in his poetry, biography, short stories and essays), Baron reveals the theological, symbolic and linguistic basis of modern economy. It allows her to describe a specific literary “experience of economy” and penetrating analyze of main themes of Wat’s work. One of the aims of the review is to rethink Baron’s proposition as a part of the new, thematically orientated history of polish modern literature. The other is to check, if Wat’s and Baron’s strictly modern and humanistic view of the economic systems can be still subversive and helpful against postmodern, mathematically reinforced capitalistic rhetoric

Instead of Szymborska? Krystyna Miłobędzka and the roots of modern ecopoetry in Poland

The paper deals with the topic of ecologically oriented poetry of Krystyna Miłobędzka as a vital tradition for 21st-century Polish ecopoets. The author tries to trace the changes in the poetic canon after 1990 and shows the increasing interest in Miłobędzka’s poetry among modern poets. By analyzing mainly meta-poetic texts, the paper contrasts Miłobędzka’s posthumanistic, “event-driven” way of writing with the humanistic lyrical subject of Wisława Szymborska’s poetry. The author presents the former as more influential and more productive for modern, ecopoetic styles, including elements such as: waking the awareness, organic perspective of language, an egalitarian way of life and thinking about relations in categories of space and adhesion rather than domination.The paper deals with the topic of ecologically oriented poetry of Krystyna Miłobędzka as a vital tradition for 21st-century Polish ecopoets.

“The words are like unemployed people”. A few preliminary notes on the economic paradoxes of the avant-garde’s language

The paper is an attempt to outline a few problems connected with economic modes of reading the historic avant-garde, mainly its poetry. The author recapitulates a short history of its studies based on symbolic economies in order to consider possible semantic differences, resulting in the various uses of economic analogy in the discourse of the first avant-garde. The article focuses on Futurist and Constructivists movements, trying to sketch conflicts between political commitment and artistic autonomy, possible economies of sign and some sources of the “economic imagination”

Comportamiento al impacto de gotas sobre hojas de repollo morado (brassica oleracea l. var. capitata)

Debido a su importancia en varias aplicaciones industriales, el impacto de gotas sobre superficies sólidas ha sido bastante estudiado. Sin embargo, las investigaciones en impactos de gotas sobre superficies de vegetales son muy escasas. En este trabajo se determina el comportamiento del impacto de gotas en superficies de repollo morado y se evalúa la influencia de la viscosidad y la tensión superficial. El comportamiento frente al impacto de los fluidos evaluados sobre la superficie de repollo morado fue medido utilizando una cámara de alta velocidad (1250 fotos/s) a diversas alturas de impacto, para un rango de número de Weber de 100 a 800. Los resultados muestran que el factor de extensibilidad máxima incrementa con el aumento de la velocidad de impacto y menor tensión superficial de gotas. La viscosidad tiene una gran influencia sobre el factor de extensibilidad máxima y la dinámica del impacto. Además, para líquidos de baja viscosidad (agua y Tween20-agua), el factor de extensibilidad máxima (ξmax) es proporcional a We1/4. Finalmente, para lograr que la gota no rebote y se mantenga en la superficie del repollo morado, en la aplicación de recubrimientos comestibles por aspersión se puede aumentar la viscosidad o disminuir la tensión superficial del líquidoLiquid drop impact on solid surfaces has been well studied due to its wide industrial application; however, there are very few studies of liquid drop impact on vegetable surfaces. The present work determined the drop impact pattern on purple cabbage leaves’ surface and evaluated the influence of water drop viscosity and surface tension. The pattern of fluid impact on cabbage surface was evaluated by using a high-speed camera (1250 frames/s) at different impact heights for Weber numbers ranging from 100-800. The results showed that greater maximum spread factor was achieved with higher impact speed and lower surface tension drops. Viscosity had great influence on maximum spread factor and on dynamic impact. Maximum scaled spread factor ξmax was We1/4 for low viscosity water drops (water and Tween20-water). Fluid viscosity could be increased or surface tension decreased to prevent droplet rebound and keep them on purple cabbage surface by spraying them with an edible coating

Miniaturization in Biocatalysis

The use of biocatalysts for the production of both consumer goods and building blocks for chemical synthesis is consistently gaining relevance. A significant contribution for recent advances towards further implementation of enzymes and whole cells is related to the developments in miniature reactor technology and insights into flow behavior. Due to the high level of parallelization and reduced requirements of chemicals, intensive screening of biocatalysts and process variables has become more feasible and reproducibility of the bioconversion processes has been substantially improved. The present work aims to provide an overview of the applications of miniaturized reactors in bioconversion processes, considering multi-well plates and microfluidic devices, update information on the engineering characterization of the hardware used, and present perspective developments in this area of research

A pressure drop correlation for low Reynolds number Newtonian flows through a rectangular orifice in a similarly shaped micro-channel

Current microfabrication methods mean that rectangular orifices in similarly shaped micro-channels are often found in microfluidic devices. The power required to overcome the pressure drop across such orifices is often of importance. In the contribution reported here, numerical results for low Reynolds number incompressible Newtonian fluid flow through rectangular orifice in similarly shaped micro-channel have been used to develop a correlation for pressure drop arising from the orifice. The correlation, which was motivated by theoretical developments, indicates that the pressure drop is proportional to the average velocity through the orifice, and a function of the orifice contraction ratio, length-to-width ratio and, most particularly, aspect ratio.V.
