Predators and competitors of vertebrates can in theory reduce the density of infected nymphs (DIN)-an often-used measure of tick-borne disease risk-by lowering the density of reservoir-competent hosts and/or the tick burden on reservoir-competent hosts. We investigated this possible indirect effect of predators by comparing data from 20 forest plots across the Netherlands that varied in predato...

tinere talente recrutate de profesorul Thoma Ionescu, a cărui intuiţie în alegerea colaboratorilor, viitorilor profesori de chirurgie, şefi de şcoală la rândul lor, nu a dat niciodată greş. Născut la 14 mai 1870 în oraşul Bârlad, acest fiu strălucit al pământului Moldovei, a reuşit prin calităţile sale înnăscute, dar mai ales printr-o muncă ordonată şi neobosită, să făurească o operă nepieritoa...

Many animals, including humans, rely on active tactile sensing to explore the environment and negotiate obstacles, especially in the dark. Here, we model a descending neural pathway that mediates short-latency proprioceptive information from a tactile sensor on the head to thoracic neural networks. We studied the nocturnal stick insect Carausius morosus, a model organism for the study of adapti...

In this paper we have analyzed the phytoestrogen content of Glycyrrhiza glabra roots harvested from four different locations in Syria. The presence of eight phytoestrogen compounds was simultaneously assessed through a LC-MS method, before and after hydrolysis. All tested extracts contain daidzein, daidzin, genistein, formononetin, ononin and coumestrol. Rezumat În această lucrare am analizat c...

Lactonic sophorolipids were produced by the yeast Candida Bombicola ATTC 22214 (Torulopsis bombicola) in a 3L bioreactor using batch cultivation, with corn oil and glucose as carbon sources. The main compound of the lactonic mixture was separated from the mixture by column chromotography and was identified as 17 hydroxyoctadecanoic-1’,4’’-lactone 6’ 6’’ diacetate sophorolipid. Surface tension m...

PURPOSE The aim of this work was to implement, validate, and compare two procedures for routine image quality (IQ) assurance in dental cone-beam computed tomography (CBCT): 1. the German standard DIN 6868 - 161 introduced in 2013 and 2. the established standard IEC 61,223 - 3-5 for clinical CT x-ray equipment referenced as "DIN" and "IEC" below. MATERIALS AND METHODS The approximated in-plane...

The preceding DIN 6800-2 (1997) protocol has been revised by a German task group and its latest version was published in March 2008 as the national standard dosimetry protocol DIN 6800-2 (2008 March). Since then, in Germany the determination of absorbed dose to water for high-energy photon and electron beams has to be performed according to this new German dosimetry protocol. The IAEA Code of P...

Research on early speech production has often argued that children’s representations start out being holistic. They receive more phonological feature specifications in the course of development. In this talk, we will briefly review the arguments from early production for underspecified representations, and subsequently focus on two sets of perception studies, which both confirm the underspecifi...

In this paper, we present a task scheduling heuristic, based on a parallel genetic algorithm (PGA). The algorithm schedules parallel programs, represented as directed acyclic graphs (DAGs), onto multi-processor systems with dynamic interconnection networks (DIN). It combines PGA with list scheduling approach and takes into account inter-processor communication cost, link contention in the DIN a...

Pancreatic ductal adenocarcinoma (PDAC) has one of the poorest prognoses of all malignancy types. To improve the survival of patients with PDAC, the development of novel anticancer agents is warranted. Riproximin (Rpx) is a newly identified plant lectin, which was isolated from Ximenia americana. The ribosome inactivating protein of type II exhibits potent anticancer activity as recently demons...
