Scientific Opinion on an application by Syngenta (EFSA-GMO-DE-2009-66) for placing on the market of herbicide tolerant and insect resistant maize Bt1…

2015

Question number: EFSA-Q-2009-00444 on request from Competent Authority of Germany; The EFSA GMO Panel previously assessed the four single events combined to produce a four-event stack maize Bt11 × MIR162 × MIR604 × GA21 and did not identify safety concerns. In this opinion, the EFSA GMO Panel assesses the four-event stack maize and all its subcombinations independently of their origin. No new data on the single events, leading to modification of the original conclusions on their safety, were identified. The molecular, agronomic, phenotypic and compositional data on the four-event stack maize did not give rise to safety concerns and there is no reason to expect interactions between the singl…

The growth of soil fungi Penicillium in the presence of N-(2-pyridylamino)methylenebisphosphonate as an alternative source of nutrients

2017

Kwas N-(2-pirydyloamino)metylenobisfosfonowy wykazują dużą aktywność herbicydową. W związku z tym należy zbadać jego odziaływanie na mikroorganizmy glebowe. Celem przeprowadzonych badań była ocena zdolności glebowych szczepów Penicillium do wzrostu w obecności kwasu N-(2-pirydyloamino)metylenobisfosfonowego jako alternatywnego źródła fosforu lub azotu lub węgla. Hodowle grzybów prowadzono w pełnym i zmodyfikowanym mineralnym podłożu Czapek, w temperaturze 25°C, przez 1–4 tygodnie. Modyfikacja podłoża polegała na wprowadzeniu 1 mM kwasu N-(2 pirydyloamino)metylenobisfosfonowego jako alternatywnego źródła składników odżywczych. Kontrolę względną stanowił wzrost grzybów w pełnym mineralnym pod…

Data from: Symbiotic polydnavirus and venom reveal parasitoid to its hyperparasitoids

2018

Symbiotic relationships may provide organisms with key innovations that aid in the establishment of new niches. For example, during oviposition, some species of parasitoid wasps, whose larvae develop inside the bodies of other insects, inject polydnaviruses into their hosts. These symbiotic viruses disrupt host immune responses, allowing the parasitoid’s progeny to survive. Here, we show that symbiotic polydnaviruses also have a downside to the parasitoid’s progeny by initiating a multi-trophic chain of interactions that reveals the parasitoid larvae to their enemies. These enemies are hyperparasitoids that use the parasitoid progeny as host for their own offspring. We found that the virus …

Herbivore-Induced Changes in Cotton Modulates Reproductive Behavior in the Moth Spodoptera littoralis

2017

Plants produce chemical defense compounds to resist herbivore attack either by repelling the herbivores or attracting natural enemies of the herbivores. We have previously shown that volatile compounds from cotton released in response to herbivory by conspecifics reduce oviposition in cotton leafworm moth Spodoptera littoralis. It remained, however, unclear whether herbivore-induced changes also affect moth pre-mating and mating behaviors. In this study we examined the effect of herbivore-induced changes in cotton on reproductive behaviors i.e., female calling, male attraction and investment, and mating behavior in S. littoralis. We found a reduction in the number of females calling i.e., f…

Edukacja historyczna: Polska – Europa – świat.Jak przedstawiać historię Polski, by Europa i świat chciały ją poznawać?

2020

This publication has been prepared by a group of doctoral studens at the Institute of History of the University of Opole, as a result of discussions on the prospects for the development of historical education in Poland, Europe and the world, undertaken during the course: Historical education: Poland – Europe – the World. The result of these considerations is this article, which proposes some possibilities of presenting the history of Poland in an objective manner, at the same time one that may arouse interest outside Poland. The content of the article is a proposal to promote prominent figures associated with Poland over the cen- turies, people of different sexes, professions and fields of…

X-ray Emission in protostellar jets

2005

Prompted by the recent detection of X-ray emission from Herbig-Haro objects, we studied the interaction between a supersonic jet originating from a young stellar object and the ambient medium; our aim is to investigate the mechanisms causing the X-ray emission. Our model takes into account the radiative losses from optically in plasmas and Spitzer's thermal conduction including saturation effects. We explored the parameter space defined by the density contrast between the ambient medium and the jet and by the Mach number, to infer the configurations which can give rise to X-ray emission. From the models, we derived the X-ray emission as it would be observed with Chandra/ACIS-I and XMM-Newto…
