Conflicts in Energy Transitions : Eine Reflexion über das online-Seminar für Master-studierende vom SoSe 2020

Das Seminar „Conflicts in Energy Transitions“, welches im Sommersemester 2020 von Prof. Dr. Michael Böcher und Dr. Ulrike Zeigermann angeboten wurde, stellte sich - in digitaler Form - den aktuellen Diskussionen über erneuerbare Energien, deren Konfliktpotenzialen und Zukunftsausblicken. Das Seminar wurde in drei Themenabschnitte unterteilt, um Struktur in die Komplexität des Themenfeldes zu bringen, sowie das asynchrone Lernen zu fördern. Diese Themenfelder werden im Folgenden vorgestellt und diskutiert, inwiefern dieser Aufbau den Studierenden das selbstverantwortliche Bearbeiten der Module, welche alle vier Wochen in synchroner - und aufgrund der Covid-19-Pandemie in digitaler Form - besprochen wurden, ermöglichte

Video Watermarking Based on Interactive Detection of Feature Regions

International audienceVideo watermarking is very important in many areas of activity and especially in multimedia applications. Therefore, security of video stream has recently become a major concern and has attracted more and more attention in both the research and industrial domains. In this perspective, several video watermarking approaches are proposed but, based on our knowledge, there is no method which verified the compromise between invisibility and robustness against all usual attacks. In our previous work, we proposed a new video watermarking approach based on feature region generated from mosaic frame and multi-frequential embedding. This approach allowed obtaining a good invisibility and robustness against the maximum of usual attacks. In our future work, we propose to optimize the choice of the region of interest by using crowdsourcing technique. This last one is an emerging field of knowledge management that involves analyzing the behavior of users when the

Spectroscopic Study of Ni(II)-4, 4’, 4’’, 4’ ’’ – Tetrasulfophthalocyanine In Aqueous Solution

It was determined spectrally that a monomer-dimer equilibrium exists in aqueous solutions of Ni-TSPC4- over a concentration range of 5 x 10-8 – 10-4 M. Equilibrium measurements were made under natural ionic strength conditions at 29°, 39° and 49°C. The values obtained for the equilibrium constants at 29°, 39° and 49°C were 2.4 x 108, 6.6 x 107 and 2.9 x 107 M-1, respectively. These results indicated that the equilibrium strongly favors dimer formation. This study also showed that nickel is second to copper in enhancing the dimerization of metallotetrasulfophthalocyanine complexes. However, metals in general inhibit dimer formation relative to the free ligand. The dimerization reaction of Ni-TSPC4- is exothermic with thermodynamic parameters of ΔG° = -11.6 kcal/mole, ΔH = -20.9 kcal/mole, and ΔS = -31 e.u. The dimerization process is thus favored from an energetic point of view despite the unfacorable entropy change. Spectral measurements made on Ni-TSPC4- in aqueous pyridine solutions in the concentration range of .05 - 6.0% pyridine (by volume) indicated a dipyridinated dimer complex of Ni-TSPC4- was formed. Using a modified version of the Benesi-Hildebrand equation, the following equilibrium was proposed : D + 2Py = D(Py)2. The overall equilibrium constants for this system at 15°, 21°, 30° and 40°C were 1.7, 1.9, 2.8, 3.6 and 4.4 M-2, respectively. The equilibrium reaction is endothermic with thermodynamic parameters of: ΔG=6.2 kcal/mole, ΔH =6.9 kcal/mole, and ΔS=25 e.u. Thus, the equilibrium reaction was favored thermodynamically due to the favorable entropy change associated with the process. Ligand studies indicated that only pyridine and polupyridine ligands bind to Ni-TSPC4- and cause a spectral change. This study also showed that Ni-TSPC4- cannot be used as an oxygen carrier in biological systems

Evaluation of Inhibitory Activity of the Aqueous & Alcoholic Extract of Citrullus Colocynthis towards Staphylococcus Aureus

Number of chemical and alcoholic and aqueous extracts have been prepared from four parts of Citrulluss Colocynthis which is the study focus that includes seeds, core, shell and fruit. The primary chemical diagnosis results show that the plant parts of the Citrullus Colocynthis of aqueous and alcoholic extracts contain the active ingredients, such as sSponins, Flavonoids, Coumarins, Resins, Alkaloids, Tannins, Phenols , Glycosides and PH rangd between 5.34-5.63 with LSD=(P<0.05). All extracts for each part of plant were tested or examined for antimicrobial activity toward Staph. Aureus from different cutaneous infections (S1, S2, S3, S4, and S5). The results showed that antimicrobial activity depend on kind of extract and tested microorganism. The inhabitation zone of aqueous extracts of dried parts of plants against S1 ranged between 5 mm for core and fruits, 9mm for  seeds and 10mm for shell with LSD=(P<0.05), while S2 ranged between (3-7) mm for fruits and seeds respectively with LSD=(P<0.05), S3 (1-13) mm for shell and seeds respectively with LSD=(P<0.05), S4 (1-5) mm for fruits and shell with LSD=(P<0.05), and S5 (0-9) mm also for fruits and shell respectively with LSD=(P<0.05). While alcoholic extracts for dried parts of plant against S1 ranged between (10-5)mm for all parts of plants, S2(5-15), S3(10-15) mm. S4(5-10)mm and S5(5mm) for all parts with LSD=(P<0.05). while fresh alcoholic extracts for all parts of plant against  S1(6mm) for core and (4mm) against S5 for core with LSD=(P<0.05). te sage fresh alcoholic extract was not active at different Staph. Aureus with LSD=0. Keywords: Citrullus Colocynthis, methanolic extract, aqueous extract, biological activity

Fungal Biofilms and Drug Resistance

Candida species, including the novel opportunistic pathogen Candida dubliniensis, are now emerging as major agents of nosocomial infections. Many such manifestations of infections associated with the formation of Candida biofilms include those occurring on devices such as indwelling intravascular catheters. Fungal biofilm-associated infections are frequently refractory to conventional therapy because of resistance to antimicrobial agents. This resistance could be in part due to the surface-induced upregulation of drug efflux pumps. Biofilm-associated Candida show uniform resistance to a wide spectrum of the currently available conventional antifungal agents, which implies that antimicrobial drugs that specifically target biofilm-associated infections are needed. The novel classes of antifungal agents, the lipid formulation of amphotericins, and the echinocandins have demonstrated unique antifungal activity against the resistant Candida biofilms, providing a breakthrough in the treatment of life-threatening invasive systemic mycoses. The use of drugs effective in combating biofilm-associated infections could lead to major developments in the treatment of fungal implant infections

Sair para o mato: estratégia yanomami contra a Covid-19

Con el avance de Covid-19, los yanomami del río Marauiá (Amazonas, Brasil) están actualizando una práctica tradicional de movilidad (wayumɨ) como estrategia de resistencia y supervivencia. Contra la nueva pandemia, abandonan las aldeas y se refugian en el bosque, invirtiendo el enfoque histórico hacia los no indígenas (napë pë), rechazando la proximidad y la convivencia. Hasta que dejaron sus aldeas, un interlocutor compartió con nosotros noticias y reflexiones sobre el momento en que vivimos y es a partir de estas conversaciones que traemos algunas reflexiones sobre esta práctica y la posibilidad de pensar y aprender de las estrategias yanomami para enfrentar epidemias (xawara).With the advance of Covid-19, the Yanomami of the Marauiá River (Amazonas, Brazil) are updating a traditional practice of mobility (wayumɨ) as a strategy of resistance and survival.
