    251 Rubus leaves mined by three species of leaf miners, Metallus pumilus (Klug, 1816), Emmetia heinemanni (Wocke, 1871) and Ectoedemia rubivora (Wocke, 1860), were collected between 2011 and 2014 in order to rear out their parasitoids. No parasitoids have been reared out from Ectoedemia rubivora, but we have identifi ed 3 parasitoid species from Emmetia heinemanni and 5 species from Metallus pumilus. With 2 tables

    Non-calorimetric determination of absorbed power during magnetic nanoparticle based hyperthermia

    Nanomagnetic hyperthermia (NMH) is intensively studied with the prospect of cancer therapy. A major challenge is to determine the dissipated power during in vivo conditions and conventional methods are either invasive or inaccurate. We present a non-calorimetric method which yields the heat absorbed during hyperthermia: it is based on accurately measuring the quality factor change of a resonant radio frequency circuit which is employed for the irradiation. The approach provides the absorbed power in real-time, without the need to monitor the sample temperature as a function of time. As such, it is free from the problems caused by the non-adiabatic heating conditions of the usual calorimetry. We validate the method by comparing the dissipated power with a conventional calorimetric measurement. We present the validation for two types of resonators with very different filling factors: a solenoid and a so-called birdcage coil. The latter is a volume coil, which is generally used in magnetic resonance imaging (MRI) under in vivo condition. The presented method therefore allows to effectively combine MRI and thermotherapy and is thus readily adaptable to existing imaging hardware.Comment: 7 pages, 3 figures+Supplementary Material (2 pages, 3 figures
