Development of fly ash-based geopolymer microstructure at room temperature
(Novpress Sro, Brno, 2011)
The development of geopolymers, as an alternative to traditional cement, by alkali activation of fly ash is a research topic in the scientific community. Many authors have agreed that there is a strong link between mechanical ...
Sintered strontium hexaferrite shaped by injection moulding in unidirectional magnetic and electromagnetic field
(European Powder Metallurgy Association (EPMA), 2010)
Strontium hexaferrite permanent magnets were produced by powder injection molding (PIM). The feedstock for powder injection molding was prepared by mixing strontium hexaferrite powder with a "Solvent system" organic binder. ...
Fish Stock Management Cooperation in the Lower Danube Region: A Case Study of Sturgeons and Pontic Shad
(Springer, Dordrecht, 2012)
The Danube River is 2,857 km long and navigable along the major part of its flow (2,411 km). Human activities have started to influence Danube River flow more significantly since the sixteenth century, through the flood ...
Structural organisation of the wood polymers in the wood fibre structure
(China Light Industry Press, Beijing, 2011)
The organisation of the major polymers in the wood fibre structure has a large impact on the properties of the structure. Numerous studies have been devoted to the cellulose microfibril arrangement, the structure providing ...
Chipless wireless sensor node
(MIPRO 2012 - 35th International Convention on Information and Communication Technology, Electronics, 2012)
A wireless sensor node based on a chipless RFID tag with integrated sensor element is presented. The chipless tag is multiresonator-based and encodes data as spectral signature. The sensor element is attached to a dedicated ...
In vitro nematicide screening of some essential oils from citrus plants
(Plant Protection Society of Serbia, 2019)
Essential oils (EOs) have historically been used for centuries in folk medicine, and nowadays they seem to be a promising control strategy against wide spectra of pathogens, diseases, and parasites. Studies on free-living ...
Qualitative and quantitative changes in the ichtyofauna of the danubian reservoirs after the construction of the iron gates hydropower plant dams / Kvalitativno-kvantitativne promene ihtiofaune u protočnim dunavskim akumulacijama posle izgradnje brana đerdapskih hidrolelektrana
(Serbian Acad Sciences Arts, Belgrade, 2018)
Human society reaps immense benefits from rivers and in the course of the last century man has considerably altered rivers, using them as waterways, for irrigation, energy production, water intakes, commercial and recreational ...
Impedance Response of Pseudobrookite Thick Films with a Sandwich Configuration
(IEEE Computer Society, 2017)
We have investigated the impedance response of pseudobrookite thick films screen printed on alumina substrate in the temperature interval from room temperature to 350 degrees C in the frequency range 100 Hz - 1 MHz. Two ...
Printed 3-D Stacked Chipless RFID Tag with Spectral and Polarization Encoding Capacity
(IEEE Computer Society, 2016)
A fully printable 3D stacked chipless RFID tag on a 50-mu m thin polyimide film is presented. The tag consists of multi-layer cross-polarized dipole resonators which overlap. The data encoding is performed in the multiresonating ...
Possibility of Aphis pomi control in apple orchards with azadirachtin
(Int Soc Horticultural Science, Leuven 1, 2016)
Aphids occur regularly in apple orchards and cause severe damages. This research aimed to assess the efficacy of biological - azadirachtin (10 g a.i. L-1) 0.2% and chemical insecticides - chlorpyrifos + cypermethrin (50 + ...
