Reduced graphene oxide-based nanometal-composite containing copper and silver nanoparticles protect tomato and pepper against Xanthomonas euvesicatoria infection

Xanthomonas euvesicatoria (Xe) is of the genera Xanthomonas, which causes a bacterial spot disease that affects tomato and pepper plants, resulting in significant economic losses. Commonly used bactericides lead to pathogen resistance, environmental contamination and a current risk to human health. Herein, a nanocomposite consisting of Cu and Ag loaded onto reduced graphene oxide (rGO) was synthesized, characterized and tested. After confirmation of the antibacterial properties in vitro, nanocomposites at concentrations of 50 and 500 µg mL MINUS SIGN 1 were applied to protect tomato and pepper plants under controlled greenhouse conditions. The tomato and pepper plants indicated significantly lower disease severity when treated with the nanocomposite (15.6 and 16.7%, respectively) than when treated with the commercial copper-based bactericide Kocide(R) 2000. The nanocomposite was demonstrated as a high-efficiency biocide and has the potential for crop disease management with no phytotoxic effect.O

Preparation of magnetic nanoparticles by one step synthesis with morphology of particles changed based on time of reaction and temperature treatment

In present study, nanosized iron oxides particles are synthetised by easy one step precipitation from Mohric salt (NH4)(2)Fe(SO4)(2)center dot 6H(2)O reacting with sodium hydroxide solution in temperature up to 60 degrees C. When changing the time of reaction, the iron oxide particles of different shape are prepared and when drying wet extracted particles at elevated temperature of 60 degrees C the change of 2D shaped morphology is observed. Depending on the time of reaction different ratios of FeOOH and Fe3O4 are obtained in this study. DTA - TGA, XRD, FTIR and SEM are used for the characterisation of particles in this study

Studenti učitelství mezi tacitními a explicitními znalostmi

V publikaci jsou shrnuty současné pohledy na (tacitní) znalosti z hlediska filozofického, pedagogického a výzkumného. Je výzvou k porozumění tomuto komplexnímu konceptu. Je v ní prezentován soubor výzkumných studií zkoumajících tacitní dimenzi znalostí studentů učitelství.V publikaci jsou shrnuty současné pohledy na (tacitní) znalosti z hlediska filozofického, pedagogického a výzkumného.

Je v ní prezentován soubor výzkumných studií zkoumajících tacitní dimenzi znalostí studentů učitelství.The book summarizes the current view of (tacit) knowledge in philosophy, educational science, and research and challenges our understanding of this complex concept. Drawing on this, a series of research studies exploring the tacit dimension of student teachers' knowledge is presented

Progress and trends in pediatric hematopoietic cell transplantation in Central-East European countries

Hematopoietic cell transplantation (HCT) is widely used as a treatment for acquired and congenital disorders. In recent years, a significant increase in transplant activity around the world has been observed, especially in Eastern European countries. This article aimed to assess progress and trends in pediatric HCT in Central-Eastern European countries between 2013 and 2018. Transplant activity survey in 2013 and 2018 in nine Central-Eastern European countries (Czech Republic, Croatia, Hungary, Lithuania, Poland, Romania, Slovakia, Slovenia, and Ukraine) was performed. The highest transplant rates in total were found in the Czech Republic and Hungary. When calculated per 10 million of the pediatric population, a 25.9% increase in the number of allo-HCT was observed with the highest in Croatia, Romania, Lithuania, and Poland; and a 12.2% increase in the number of auto-HCT was observed with the highest in Slovenia, Slovakia, Romania, Poland, Ukraine, and Croatia. We have shown, over the years 2013 and 2018, in some countries of Central-Eastern Europe that there was a significant increase in transplant activity, especially in those with the lower rates. This increase was observed mainly in centers already existing in 2013, especially in the allo-HCT setting. The rise of activity was significantly less influenced by the creation of new transplant centers or the increase in the number of pediatric transplant beds. In conclusion, our analysis indicates that in the Czech Republic, Hungary, Lithuania, and Slovenia, the actual infrastructure and the number of HCTs cover the needs, whereas in other countries, especially in Romania and Ukraine, the number of HCT needs to be increased

Forest leaf litter beetles of Taiwan: first DNA barcodes and first insight into the fauna

We report the publication of 953 DNA barcodes of forest leaf litter beetles from central Taiwan, in total representing 334 spe- cies of 36 beetle families. This is the first bulk of data from the Taiwanese Leaf Litter beetles project focused on uncovering the under-explored diversity of leaf litter beetles across Taiwan. Based on these data, we provide the first records of the following taxa for Taiwan: family Sphindidae (genus Aspidiphorus Ziegler, 1821); tribes Trichonychini, Ctenistini, and Bythinoplectini (all Staphylinidae: Pselaphinae); genera Gyrelon Hinton, 1942, Thyroderus Sharp, 1885, Cautomus Sharp, 1885 (all Cerylonidae), Dermatohomoeus Hlisnikovský, 1963 (Leiodidae), Paraploderus Herman, 1970 (Staphylinidae: Oxytelinae), Thinocharis Kraatz, 1859 (Staphylinidae: Paederinae), Cephennodes Reitter, 1884, Napoconnus Franz, 1957 (both Staphylinidae: Scydmaeninae), Bicava Belon, 1884 (Latridiidae), Otibazo Morimoto, 1961, Seleuca Pascoe, 1871 and Acallinus Morimoto, 1962 (all Curculioni- dae); species Oodes (Lachnocrepis) japonicus (Bates, 1873) (Carabidae: Licininae), Drusilla obliqua (Bernhauer, 1916) (Staphylin- idae: Aleocharinae) and Coccotrypes advena Blandford, 1894 (Curculionidae: Scolytinae). The records of Anapleus Horn, 1873 (Histeridae) and Batraxis Reitter, 1882 (Staphylinidae: Pselaphinae) have been confirmed. The male of Sivacrypticus taiwanicus Kaszab, 1964 (Archeocrypticidae) is described for the first time. Gyrelon jenpani Hu, Fikáček & Matsumoto, sp. nov. (Cerylon- idae) is described, illustrated, and compared with related species. DNA barcodes associated larvae of 42 species with adults, we are concisely illustrating some of these: Oodes japonicus, Perigona cf. nigriceps Dejean, 1831 (both Carabidae), Ptilodactyla sp. (Ptilodactylidae), Maltypus ryukyuanus Wittmer, 1970 (Cantharidae), Drusilla obliqua, Myrmecocephalus brevisulcus (Pace, 2008), Diochus sp., Mimopinophilus sp. (all Staphylinidae), Stelidota multiguttata Reitter, 1877, Lasiodites inaequalis (Grouvelle, 1914) (both Nitidulidae), Lagria scutellaris Pic, 1910, and Anaedus spinicornis Kaszab, 1973 (both Tenebrionidae). We also report the first cases of Rickettsia infections in Scydmaeninae and Pselaphinae. All data (sequences, metadata, and voucher photos) are made public in BOLD database and in a Zenodo Archive
