Carlina acaulis and Trachyspermum ammi essential oils formulated in protein baits are highly toxic and reduce aggressiveness in the medfly, Ceratitis…

2021

Abstract Essential oil (EO)-based botanical insecticides are considered a promising option for Integrated Pest Management (IPM). However, the sublethal effects of EO-based insecticides are understudied. No information is available on the potential effects of EO exposure on insect aggressive traits. In this study, the toxicity of two EOs with documented efficacy on insect vectors and agricultural pests, and which were obtained from the roots of silver thistle (Carlina acaulis L., Asteraceae) and seeds (i.e. schizocarps) of ajwain (Trachyspermum ammi (L.) Sprague, Apiaceae), was evaluated against adults of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (medfly), a cosmopolitan fr…

The growth of cloud-based services is mainly supported by the core networking infrastructures of large-scale data centers, while the scalability of these services is influenced by the performance and dependability characteristics of data centers. Hence, the data center network must be agile and reconfigurable in order to respond quickly to the ever-changing application demands and service requirements. The network must also be able to interconnect the big number of nodes, and provide an efficient and fault-tolerant routing service to upper-layer applications. In response to these challenges, the research community began exploring novel interconnect topologies, namely: Flecube, DCell, Ficonn…

On the development of a communication-aware task mapping technique

2004

Clusters have become a very cost-effective platform for high-performance computing. In these systems, although currently existing networks actually provide enough bandwidth for the existing applications and workstations, the trend is towards the interconnection network becoming the system bottleneck. Therefore, in the future, scheduling strategies will have to take into account the communication requirements of the applications and the communication bandwidth that the network can offer. One of the key issues in these strategies is the task mapping technique used when the network becomes the system bottleneck.In this paper, we propose a communication-aware mapping technique that tries to mat…

Some Remarks on the Relationship between Secession and General International Law in the Light of the ICJ’s Kosovo Advisory Opinion

2012

How is it possible to regard something that is not prohibited, as illegal? What are the resulting consequences of fact and law? This chapter suggests that a reasonable way to reconcile these two assertions is to admit that they refer to two profiles of the phenomenon in question that must be kept separate. Independence is not prohibited, but not all means to reach it are allowed under general international law. To render this concept, the author submits the idea of a normative "due process" seen as a set of rules giving no legal entitlement to statehood nor determining the creation of a State, but forming a normative course through which factual processes should be legally channelled. The c…

The European Union's Proposal for an International Investment Court: Significance, Innovations and Challenges Ahead

2016

International audience; Rampant discontent with the current system that governs the protection of international investment and the functioning of investment tribunals has led to a widespread view that there is an urgent need for reform. This is particularly pronounced in the context of investor-state dispute settlement (ISDS). The European Union (EU) has responded to this need by proposing the creation of an international investment court. With its political weight, the EU confers unprecedented legitimacy on the critics of the current ISDS system and reveals investment dispute settlement in the light of public international law, breaking with its background in commercial litigation. The art…

New Aspects of the Mesolithic-Neolithic Cemeteries and Settlement at Zvejnieki, Northern Latvia

2017

The paper reflects upon recent international research at Zvejnieki in northern Latvia, a renowned complex of a burial ground and two settlement sites used in the Mesolithic and Neolithic. Since its discovery and first excavations in the 1960s, Zvejnieki continues to produce evidence that provides new grounds for understanding mortuary practises and ancient lifeways. This information is relevant for other contemporary sites in Europe revealing new and hitherto unexpected elements of burial traditions. It is suggested that the Zvejnieki population was partly mobile, and the site was one of the places to bury the dead. The ancestral link was established through transportation and use of occupa…

Intracellular trafficking of endogenous fibroblast growth factor‐2

2008

We have previously reported how the release of fibroblast growth factor-2 (FGF-2) is mediated by shed vesicles. In the present study, we address the question of how newly synthesized FGF-2 is targeted to the budding vesicles. Considering that in vitro cultured Sk-Hep1 hepatocarcinoma cells release FGF-2 and shed membrane vesicles only when cultured in the presence of serum, we added serum to starved cells and monitored intracellular movements of the growth factor. FGF-2 was targeted both to the cell periphery and to the nucleus and nucleolus. Movements toward the cell periphery were not influenced by drugs affecting microtubules, but were inhibited by cytocalasin B. Involvement of actin in …

From the banks of Upper Tigris River to the Zagros Highlands. The Tübingen Eastern Ḫabur Archaeological Survey. Trial season 2013

2016

After decades of strife and unrest, during which Northern Iraq remained closed to the outside world, a new era of international scientific enterprise has begun in this region thanks to the recent democratic and civil upturn and its subsequent economic resurgence. In the last few years, together with the restoration and refurbishment of historical monuments, there has also been a spread of new archaeological undertakings in the form of surveys and excavations, the quality and quantity of which is fully shown in the present volume. A Tübingen University research project was initiated in the northernmost part of Iraqi-Kurdistan, in the province of Dohuk. The research area is located at the foo…

The oxidation of ubiquinol by the isolated rieske iron-sulfur protein in solution

1990

The pre-steady-state redox reactions of the Rieske iron-sulfur protein isolated from beef heart mitochondria have been characterized. The rates of oxidation by c-type cytochromes is much faster than the rate of reduction by ubiquinols. This enables the monitoring of the oxidation of ubiquinols by the Rieske protein through the steady-state electron transfer to cytochrome c in solution. The pH and ionic strength dependence of this reaction indicate that the ubiquinol anion is the direct reductant of the oxidized cluster of the iron-sulfur protein. The second electron from ubiquinol is diverted to oxygen by the isolated Rieske protein, and forms oxygen radicals that contribute to the steady-s…

Age and isotope geochemistry of the Archaean Pongola and Usushwana suites in Swaziland, southern Africa: a case for crustal contamination of mantle-d…

1984

The igneous rocks of the Pongola Supergroup (PS) and Usushwana Intrusive Suite (UIS) represent a case of late Archaean continental magmatism in the southeastern part of the Kaapvaal craton of South Africa and Swaziland. U-Pb dating on zircons from felsic volcanic rocks of the PS yields a concordia intercept age of 2940 ± 22Ma that is consistent with a Sm-Nd whole rock age of 2934 ± 114Ma determined on the PS basalt-rhyolite suite. The initial eNd of−2.6 ± 0.9 is the lowest value so far reported for Archaean mantle-derived rocks. Rb-Sr whole rock dating of the PS yields a younger isochron age of 2883 ± 69Ma, which is not significantly different form the accepted U-Pb zircon age. An internal …
