DDT-Contaminated Soil Treatment with Persulfate and Hydrogen Peroxide Utilizing Different Activation Aids and the Chemicals Combination with Biosurfactant
Authors: Goi Anna , Viisimaa Marika , Karpenko Oleksandr 
Published: November 2016

AbstractThe efficacy of DDT-contaminated soil treatment with hydrogen peroxide and persulfate utilizing different activation aids and the chemicals combination with biosurfactant was evaluated. The addition of a supplementary activator was able to improve the degradation of total DDT with both the hydrogen peroxide and persulfate oxidation processes indicating a lack of available activator. Ferrous iron added gradually was effectively utilized in the oxidation system with gradual addition of hydrogen peroxide, while chelated metal iron addition promoted the oxidation with more stable persulfate. The treatment with solid carriers of hydrogen peroxide, either calcium peroxide or magnesium peroxide, can be an effective alternative to the liquid one resulting in a higher degradation level of the contaminant. Strong alkalization with elevated dosages of NaOH sustained the persulfate oxidation of DDT. The addition of biosurfactant, rhamnolipid-alginate complex obtained by biosynthesis of strain Pseudomonas sp. PS-17, and EDTA improved the degradation of DDT by both persulfate and hydrogen peroxide oxidation processes indicating that the combined application of chemical oxidants and biosurfactant at natural soil pH has prospects as an effective option for contaminated soil remediation.

Treatment of Composted Soils contaminated with Petroleum Hydrocarbons using Chemical Oxidation followed by Enhanced Aerobic Bioremediation
Authors: Cajal-Mariñosa Paula , Reich Olga , Möbes Anja , Tuhkanen Tuula 
Published: November 2016

AbstractTwo different soils that had been composted to treat petroleum hydrocarbons were further treated with chemical oxidation followed by enhanced aerobic bioremediation to degrade residual hydrocarbons, mostly motor oil, that composting did not treat. Composted soils are rich in non-target organic matter that scavenges the chemical and biological amendments intended for degradation of the target contaminants, making composted soils very difficult to treat. Therefore, the design approach was to use chemical oxidation to enhance the biodegradability of the target contaminants in a subsequent step. Modified Fenton chemistry was used for chemical oxidation, and aerobic bioremediation was promoted with an oxygen releasing compound. The results showed a moderate reduction in target hydrocarbon content resulting from the Fenton treatment. However, the biochemical oxygen demand (BOD
Pretreatment of Sewage Sludge by Low-frequency Ultrasound

Published: November 2016

AbstractThe key point of waste activated sludge (WAS) pretreatment is to rupture the cell wall for allowing the release of intracellular matter that acts as a bioavailable substrate in anaerobic digestion processes. In this regard, ultrasonic irradiation has been one of the most effective tools owing to the unique properties of ultrasound to produce extreme conditions in heterogeneous liquids such as waste activated sludge. The present study investigates the impact of short-frequency ultrasound on disintegration, biodegradability and dewatering characteristics of sewage sludge by monitoring soluble chemical oxygen demand (sCOD), dissolved organic carbon (DOC), soluble proteins, total dissolved nitrogen, particle size and dewaterability of raw and sonicated sludge samples to optimize the operating parameters. The results showed that short wave ultrasound is a highly effective method of WAS treatment, because it provides high degrees of disintegration and biomass transfer from sludge solids to the aqueous phase, thus resulting in enhanced biodegradability.

Published: November 2016

AbstractThe decolouration effect of ozone on the reactive dye Reactive Red 198 in a CSTR was the subject of a series of experiments. The results showed that ozonation is capable of reducing the colour remaining in the water after using reactive dyes rapidly and effectively of around 15 minutes. The effect of the frit was analysed to check that it was not a factor limiting oxidation. The effect of flow rate and of the initial concentration of dye on the dye concentration as a function of time and at steady state were measured, and the rate of decolouration was calculated under both steady and unsteady state conditions. The flow rate was adjusted for various initial dye concentrations as well as at various flow rates of dye solutions. The apparent first order rate constant is about 0.10 min

Crafting Swords. The emergence and production of full-hilted swords in the Early Nordic Bronze Age
Authors: Bunnefeld Jan-Heinrich 
Published: November 2016

ZusammenfassungDie Schwerter in Südskandinavien und Norddeutschland wurden bisher zumeist aus einem typologischen Blickwinkel betrachtet. Deshalb werden im vorliegenden Artikel die Vollgriffschwerter der älteren nordischen Bronzezeit in Dänemark und Schleswig-Holstein aus einer herstellungstechnischen Perspektive unter Anwendung von makro- und mikroskopischer Autopsie, Röntgenuntersuchungen, Spurenelement- und Bleiisotopenanalysen untersucht. In Periode I kam das Schwert als Innovation über Importe von Schwertern der Gruppe Hajdúsámson-Apa nach Südskandinavien. Am Anfang imitierten nordische Handwerker diese Importe, wobei sie eine traditionelle massive Gusstechnik verwendeten. Erst im Laufe der späten Periode I wurden verschiedene Gusstechniken aus dem südlichen Mitteleuropa adaptiert und genutzt, um Stücke in Tradition der Hajdúsámson-Apa- and Valsømagle-Schwerter herzustellen. In Periode II entstanden die charakteristischen nordischen Vollgriffschwerter, die in Form, Verzierung und Technik jeweils sehr individuell ausfallen. Höchstwahrscheinlich wurden sie in einer größeren Anzahl von Werkstätten produziert; in manchen Fällen ist es sogar möglich, mehrere Schwerter einem Werkstattkreis, einer Werkstatt oder gar einem Handwerker zuzuordnen. In Periode III waren die nordischen Vollgriffschwerter dann sehr viel standardisierter, wurden aber dennoch wohl nicht in einer Werkstatt hergestellt. Die Entwicklung der Schwerter zeigt insgesamt eine Tendenz von einer großen Vielfalt bei Formen, Verzierungen und Techniken hin zu stärker gleichförmigen Objekten, die auch an anderen Fundgruppen zu beobachten ist. In jedem Fall demonstriert der nordische Kreis seit der späten Periode I und frühen Periode II eine eigene Identität, Metallverarbeitungs- und Schwertherstellungstradition. Sowohl die Vielfalt in Periode II als auch die Uniformität in Periode III deuten auf intensive Kommunikation und Mobilität von Handwerkern und Schwertträgern hin. Dabei wird der Einfluss von Abstammungsgruppen und Verwandtschaft hinsichtlich der Organisation des sicherlich institutionalisierten Metallhandwerks betont, während die angenommene enge Kontrolle der Produktion durch eine Elite angezweifelt wird. Ungeachtet unterschiedlicher Fähigkeiten und Kompetenzen existieren keine Hinweise auf eine bedeutsame persönliche Identität als Metallhandwerker in der Gesellschaft der älteren nordischen Bronzezeit.
Some Thoughts on the Troy Type Owl-Headed Idols of Western Anatolia
Authors: Yılmaz Derya 
Published: November 2016

ZusammenfassungGegenstand der Studie ist ein marmornes Idol, das aus dem Hügel von Maydos Kilisetepe geborgen wurde. Die Fundstelle befindet sich nahe der Stadt Eceabat, Provinz Çanakkale. Das Idol wird als Idol des Troja-Typus angesprochen, Typ 2C nach C. Blegen, bezeichnet wird es außerdem als „Eulenköpfiges Idol“, eine Ansprache, die auf Heinrich Schliemann zurück geht. Fundkartierungen zeigen, dass Idole dieser Art im westlichen Anatolien weit verbreitet waren. Dabei liegen aus lokalen Siedlungen keine identischen Exemplare vor, sondern nur solche, die ihrer Gestaltung nach variieren. Zum Verständnis der Nutzung jener Idole werden die Fundkontexte genauer beleuchtet, die mehrheitlich dem häuslichen Kontext entstammen. Angenommen werden kann daher, dass die Idole im Rahmen häuslicher Kulte Verwendung fanden. Bemerkenswert ist auch die Chronologie jener Idole, treten diese auch in einem Zeitraum von der Mitte bis zum Ende der Frühbronzezeit auf, wobei sich ihre Nutzung auch in der beginnenden mittleren Bronzezeit noch fortsetzt. Die Idole spiegeln den Glauben der Menschen und es kann angenommen werden, dass sie die Muttergöttin symbolisieren, die im Hauskult dem Schutz des Heimes dienten. Eulengesichtige Göttinnen werden außerdem auf Keramiken und Stelen dargestellt, verbreitet im dritten vorchristlichen Jahrtausend in Mesopotamien, Syrien wie auch im westlichen Mittelmeerraum mit der Iberischen Halbinsel. Die besprochenen Artefakte zeigen damit überregional weitgespannte Kontakte, den mesopotamischen Raum wie auch das Mittelmeer umfassend.

Deviations from Critical Dynamics in Interictal Epileptiform Activity

Published: November 2016

The framework of criticality provides a unifying perspective on neuronal dynamics fromin vitrocortical cultures to functioning human brains. Recent findings suggest that a healthy cortex displays critical dynamics, giving rise to scale-free spatiotemporal cascades of activity, termed neuronal avalanches. Pharmacological manipulations of the excitation-inhibition balance (EIB) in cortical cultures were previously shown to result in deviations from criticality and from the power law scaling of avalanche size distribution. To examine the sensitivity of neuronal avalanche metrics to altered EIB in humans, we focused on epilepsy, a neurological disorder characterized by hyperexcitable networks. Using magnetoencephalography, we quantitatively assessed deviations from criticality in the brain dynamics of patients with epilepsy during interictal (between-seizures) activity. Compared with healthy control subjects, epilepsy patients tended to exhibit a higher neural gain and larger avalanches, particularly during interictal epileptiform activity. Moreover, deviations from scale-free behavior were exclusively connected to brief intervals at epileptiform discharges, strengthening the association between deviations from criticality and the instantaneous changes in EIB. The avalanches collected during interictal epileptiform activity had not only a stereotypical size range but also involved particular spatial patterns of activations, as expected for periods of epileptic network dominance. Overall, the neuronal avalanche metrics provide a quantitative novel description of interictal brain activity of patients with epilepsy.SIGNIFICANCE STATEMENTHealthy brain dynamics requires a delicate balance between excitatory and inhibitory processes. Several brain disorders, such as epilepsy, are associated with altered excitation-inhibition balance, but assessing this balance using noninvasive tools is still challenging. In this study, we apply the framework of critical brain dynamics to data from epilepsy patients, which were recorded between seizures. We show that metrics of criticality provide a sensitive tool for noninvasive assessment of changes in the balance. Specifically, brain activity of epilepsy patients deviates from healthy critical brain dynamics, particularly during abnormal epileptiform activity. The study offers a novel quantitative perspective on epilepsy and its relation to healthy brain dynamics.
