About the mode of incorporation of silanol-terminated polysiloxanes into butylene terephthalate-b-dimethylsiloxane copolymers
(Elsevier, Amsterdam, 2008)
The modality of the incorporation of silanol-terminated siloxanes into copolymers with butylene terephthalate were investigated and determined. Besides siloxanes, the other participants in this well-known copolymerization, ...
Dielectric properties of barium-titanate sintered from tribophysically activated powders
(Elsevier Sci Ltd, Oxford, 1999)
It has been well known that the tribophysical (mechanical) activation could be used as a method for modification of physicochemical properties of dispersed systems such as polycrystalline mixture of oxides. In this study, ...
The effects of population densities and diet on Tribolium castaneum (Herbst) life parameters
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
The effects of population densities (10, 25, 50 and 100 adults/50 g) and three diet types (protein-rich, carbohydrates-rich and compound feed) on life parameters (first emergence, development rate, number of progeny and ...
Comparative chemometric and quantitative structure-retention relationship analysis of anisotropic lipophilicity of 1-arylsuccinimide derivatives determined in high-performance thin-layer chromatography system with aprotic solvents
(Elsevier, Amsterdam, 2020)
Numerous structurally different amides and imides including succinimide derivatives exhibit diverse bioactive potential. The development of new compounds requires rationalization in the design in order to provide structural ...
The effect of ball milling on properties of sintered manganese-doped alumina
(Elsevier, 2019)
Alumina-based compounds have many technological applications and attract great attention even after decades of investigation, due to their good chemical, electrical, and mechanical properties. A mixture of several alumina ...
Long-term continuity of steppe grasslands in eastern Central Europe: Evidence from species distribution patterns and chloroplast haplotypes
(John Wiley and Sons Inc, 2021)
The steppe grasslands of eastern Central Europe are exceptionally species rich and valuable from a nature conservation point of view. However, their historical biogeography is still poorly understood. Here we use the ...
Critical time for weed removal in corn as influenced by planting pattern and pre herbicides
(MDPI AG, 2021)
Determining the critical time for weed removal (CTWR) is essential for the development of an integrated weed management plan. Therefore, field experiments were conducted to evaluate the effects of two planting patterns ...
Effect of the Controlled High-Intensity Ultrasound on Improving Functionality and Structural Changes of Egg White Proteins
(Springer, New York, 2017)
The objective of this research was to investigate the impact of high-intensity ultrasound (HIU) generated by a probe-type sonicator (frequency 20 +/- 0.2 kHz and an amplitude of 40%) for 2-20 min on the selected functional ...
Photoactive and antioxidant nanochitosan dots/biocellulose hydrogels for wound healing treatment
(Elsevier Ltd, 2021)
Bacterial infection and their resistance to known antibiotics delays wound healing. In this study, nanochitosan dots (nChiD) produced by gamma irradiation have been encapsulated in bacterial cellulose (BC) polymer matrix ...
Shelf life study of healthy pork liver pate with added seaweed extracts from Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcata
(Elsevier Science Bv, Amsterdam, 2018)
The effect of the addition of seaweed extracts from three brown algae species [Ascophyllum nodosum (AN), Fucus vesiculosus (FV) and Bifurcaria bifurcata (BB which are a great source of natural antioxidants, on the oxidative ...
