(EN) Interactive digital artworks by nature are among the most difficult to preserve. The InterPARES project, a multinational interdisciplinary collaboration, is studying many specific cases to understand how to preserve them authentically. This essay first investigates the relation between the archival concept of authenticity, which involves the identity and integrity of the work, and performa...

— The words “monodromy” and “isomonodromy” are used in the theory of difference and q-difference equations by Baranovsky-Ginzburg, Jimbo-Sakai, Borodin, Krichever,... although it is not clear that phenomena of branching during analytic continuation are involved there. In order to clarify what is at stake, we survey results obtained during the last few years, mostly by J.-P. Ramis, J. Sauloy and...

This pilot scale study aims to test the effectiveness of an innovative compact biological system (SBBGR - Sequencing Batch Biofilter Granular Reactor) for treating municipal wastewater in tourist areas characterised by intense seasonal water demand and wastewater discharge. The results obtained after a long term operation of 463 days have shown that the proposed system is able to assure average...

BACKGROUND The aim of this work was to study the biological treatment a synthetic wastewater containing emerging contaminants. 95-day experiment conducted in an 81 L continuous flow conventional activated sludge apparatus consisting anoxic and aerobic reactors with internal recycling, clarifier recycling. Real from municipal plant Nur-Sultan city used. degradation efficiencies caffeine, metroni...

Mathematical modelling has proven to be very useful in process design, operation and optimisation. A recent trend in WWTP modelling is to include the different subunits in so-called plant-wide models rather than focusing on parts of the entire process. One example of a typical plant-wide model is the coupling of an upstream activated sludge plant (including primary settler, and secondary clarif...

This study determined PBDE levels in influent, primary effluent, and final effluent collected from diverse treatment processes including four aerated lagoons, two facultative lagoons, four primary treatments, eight secondary biological treatments and two advanced treatments. Parameters examined for correlation included seasonal temperature, community sizes, industrial inputs, and operational co...

With a view to reducing pollution in the aquatic environment, estrone (E1) and 17beta-estradiol (E2) were tested for their absorbability in water onto activated carbons (ACs) with various pore-size distributions. In batch-type adsorption measurements, all adsorption isotherms obtained were found to fit a Freundlich equation. In case of eight different kinds of commercial AC in pure water, the a...

Industri alkohol skala rumah tangga yang berada di Desa Bekonang Kabupaten Sukoharjo merupakan industri sudah lama ada dan turun temurun dari generasi ke genarasi. Proses produksi dilakukan dengan cara distilasi bahan baku utama tetes tebu. Air limbah hasil ini memiliki warna coklat pekat berbau sedikit menyengat. juga nilai COD, BOD, TSS nutrien tinggi sehingga perlu diolah terlebih dahulu seb...

La fièvre Q est une zoonose transmise essentiellement par voie aérienne dont le réservoir principal représenté les ruminants domestiques, qui constituent source de contamination pour professionnels l’élevage et la population générale. Bien qu’un cas unique transmission post-transfusionnelle ait été décrit, risque receveur se pose dans régions à forte densité car l’évolution l’infection Coxiella...
