Chronic primary headaches are widespread disorders which cause significant quality of life and socioprofessional impairment. Available pharmacological treatments have often a limited efficacy and/or can generate unbearable side effects. Electrical nerve stimulation is a well known non-destructive method of pain modulation which has been recently applied to headache management. In this review, we summarise recent advances in invasive and non-invasive neurostimulation techniques targeting pericranial structures for the treatment of chronic primary headaches, chiefly migraine and cluster headache: occipital nerve, supraorbital nerve, vagus nerve, and sphenopalatineganglion stimulations. Invasive neurostimulation therapies have offered a new hope to drug-refractory headache sufferers but are not riskless and should be proposed only to chronic patients who failed to respond to most existing preventives. Non-invasive neurostimulation devices are user-friendly, safe and well tolerated and are thus taking an increasing place in the multidisciplinary therapeutical armamentarium of primary headaches.

Dermatophytes are causing superficial mycosis in animals and humans. Depending on the geophilic, zoophilic or anthropophilic origin of the fungus but also on the immunological status of the patient, symptomatology can widely differ. Nevertheless, each species is currently associated with typical clinical manifestations, even if atypical localizations and/or clinical pictures are sometimes also reported. Diagnostic tools applied to species identification have been changing since the last two decades with the more frequent use of molecular methods currently considered nowadays as reference methods for species identification. It becomes obvious that the algorithm used for the distinction of closely related species needs to combine phenotypic and genomic methods. All these different points are discussed, and the most recent novel species causing or involved in human dermatophytosis are reported. [less ▲]

Biobased synthesis poses specific challenges due to the properties of raw materials, intermediates, and products. They are induced by the higher oxygen content as compared to fossil feedstock. Thus low vapor pressure, higher viscosity, low concentration in aqueous solution will require new, preferably liquid-based downstream processes, for which many different options can be proposed. A systematic method to evaluate such a multitude of options based on cascaded option trees is presented, which combines representation and evaluation of options on a suitably chosen level of detail. Criteria, which have to be fulfilled by the options, are flexibly evaluated ranging from input of experts to detailed simulation. Clear visualization also allows transparent communication of results to members of interdisciplinary teams and project partners. The method is demonstrated for extractive separation steps including real-world problems encountered. This includes high viscosities, presence of solids or microorganisms leading to crud formation, and optimization of process conditions solving the conflicting challenges balancing e.g. between low toxicity to microorganisms and process efficiency.

Innovations relevant to human evolution often involve subsistence technology, which can affect the success of individual groups, and Homo sapiens in general. However, Palaeolithic technologies include more than just hunting tools, and a proper understanding of hunter-gatherer ways of living requires knowledge of the organisation of diverse tasks and activities, including the manufacture and maintenance of tools and other equipment. One central aspect of technological evolution is the development of tool hafting [1, 2], which is not only restricted to hunting and gathering implements, but also affects so-called domestic tool categories. We present the results of an on-going project that focuses on hafting and use of stone tools in the Upper Palaeolithic through detailed functional analysis of selected assemblages from European key sites (Hohle Fels, Abri Pataud, Maisières-Canal), which have yielded rich lithic and organic assemblages from secure chronological contexts. Here the focus is on classic Upper Palaeolithic tool categories, such as endscrapers and burins, from the Gravettian and Magdalenian levels of the cave site Hohle Fels (Germany) [3, 4]. We suggest that domestic tools can offer a valuable source material, since for most of them, hafting is not a necessity as it is for spear and arrow tips. An increase in hafting implies an increase in time investment, which has implications for task organisation and specialisation. The Hohle Fels assemblage offers an interesting case study for temporal changes (or continuity) in the frequency and techniques of tool hafting. The projectile technology shows a clear shift from the Gravettian to the Magadalenian, marked by the introduction of a microlithic technology (backed bladelets). For other tool categories, the changes seem more subtle. Our goal is to characterise the tools used in manufacture and maintenance tasks, and to evaluate whether the Gravettian to Magdalenian transition witnesses changes in tool design and use that go beyond hunting equipment. The observed differences between tool classes and time periods are explained with a reference to details of tool use, such as the rate of edge wear development and stone tool exhaustion, as well as shifts in treatment of organic raw materials. The results suggest that domestic tools can aid in understanding long-term technological evolution, and create a baseline against which we can (re)assess the role of shifts observed in technologies that are more susceptible to morphological change, such as projectiles.

Heutige chemische Produkte basieren fast ausschließlich auf erdölbasierten Rohstoffen. Aufgrund weltweiter Bemühungen, die Abhängigkeit von fossilen Rohstoffen zu reduzieren, wird in den letzten Jahren verstärkt die Nutzung alternativer Kohlenstoffquellen wie Biomasse oder CO2 erforscht. Die alternativen Kohlenstoffquellen unterscheiden sich hinsichtlich ihrer Zusammensetzung und Stoffeigenschaften teilweise deutlich von fossilen Rohstoffen. Aus diesem Grund müssen Syntheserouten und darauf aufbauende Prozesse neu entwickelt werden. Da zum einen sehr viele Syntheserouten prinzipiell denkbar sind und zum anderen die Entwicklung der entsprechenden Prozesse aufwendig ist, wird eine Möglichkeit benötigt, begrenzte Entwicklungsressourcen sinnvoll zu steuern. Dazu sollte bereits in einem frühen Entwicklungsstadium ein quantitativer Vergleich der Syntheserouten erfolgen, um diejenigen zu identifizieren, die das größte wirtschaftliche Potential versprechen. In diesem Vortrag wird eine Methodik vorgestellt, um eine schnelle erste, auf Exergie basierte Bewertung des wirtschaftlichen Potentials einer Syntheseroute bereits in einem frühen Entwicklungsstadium durchzuführen, in dem nur wenige Informationen vorliegen. Die Idee der Methodik ist, Syntheserouten in standardisierten Prozessen abzubilden, wodurch eine automatisierte Auswertung und somit ein schnelles Screening möglich wird. Die standardisierten Prozesse umfassen sowohl den Einfluss der Reaktion durch Abbildung der Reaktionsbedingungen, Stöchiometrie, Umsatz und Selektivität als auch die Auswirkungen der Trennaufgabe. Ebenso berücksichtigt wird die Rückführung von Lösungsmitteln und ggf. nicht umgesetzten Edukten. Als zentrale Bewertungsgröße zur Abschätzung des wirtschaftlichen Potentials wird eine Kombination aus Exergie- und Rohstoffeinsatz herangezogen. Der Vorteil von Exergiebilanzen gegenüber Energiebilanzen ist, dass die Produktion von Entropie berücksichtigt wird und so die Auswirkungen einzelner Prozessschritte untersucht und zwischen verschiedenen Energieformen unterschieden werden kann. Durch Berechnung der Exergieverluste, also der Verluste von Exergie aufgrund von Entropieerzeugung in den Prozessen, ergibt sich ein quantitativer Vergleich verschiedener Syntheserouten. [less ▲]
