Woody plants and herbs as bioindicators of the current condition of the natural environment in Serbia
(Academic Journals, Victoria Island, 2011)
Being the inhabitants of all parts of the environment (water, air, soil) plants can very precisely point to the ecological conditions of the environment. Vascular plants are often used for biomonitoring of heavy metals. ...
Determination of differential heavy metal and trace element accumulation in liver, gills, intestine and muscle of sterlet (Acipenser ruthenus) from the Danube River in Serbia by ICP-OES
(Elsevier Science Bv, Amsterdam, 2011)
The accumulation of heavy metals in fish has been extensively studied and well documented. However, the research has been mainly focused on the muscle tissue, while the distribution patterns among other tissues, such as ...
Preliminary data on essential oil composition of the moss Rhodobryum ontariense (Kindb.) Kindb.
(Adac-Cryptogamie, Paris, 2011)
The essential oil composition of the moss Rhodobryum ontariense obtained by hydrodistillation was preliminary analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Thirteen compounds (86.41% ...
Free radicals and antioxidants at a glance using EPR spectroscopy
(Taylor & Francis Ltd, Abingdon, 2011)
The delicate balance between the advantageous and detrimental effects of free radicals is one of the important aspects of human (patho)physiology. The controlled production of reactive oxygen and nitrogen species has an ...
Relevance of the ability of fructose 1,6-bis(phosphate) to sequester ferrous but not ferric ions
(Elsevier Sci Ltd, Oxford, 2011)
The cytoprotective activity of F16BP has been documented in severe conditions such as convulsions, reperfusion injury, septic shock, diabetic complications, hypothermia-induced injury, UV-provoked skin damage and in other ...
A Thermal Sensor for Water Using Self-Heated NTC Thick-Film Segmented Thermistors
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2011)
A simple thermal (heat loss) sensor system was designed in a small plastic tube housing using a negative thermal coefficient (NTC) thick-film thermistor as a self-heating sensor. The voltage power supply [range constant ...
Improved Model of T-Type LC EMI Chip Filters Using New Microstrip Test Fixture
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2011)
In this paper we present an improved model of the multilayered T-type electromagnetic interference chip LC filter for printed circuit board applications, and an improved measurement technique for characterization of such ...
Determination of the size of quantum dots by fluorescence spectroscopy
(Royal Soc Chemistry, Cambridge, 2011)
There has been a lack of quick, simple and reliable methods for determination of nanoparticle size. An investigation of the size of hydrophobic (CdSe) and hydrophilic (CdSe/ZnS) quantum dots was performed by using the ...
Antimony doping effect on barium titanate structure and electrical properties
(Elsevier Sci Ltd, Oxford, 2011)
Nanopowders of pure and antimony doped barium titanate (BaTiO3-BT) were synthesized by polymeric precursors method based on Pechini process. Obtained powders were pressed and sintered at 1300 degrees C for 8 h. XRD analysis ...
Anoxia induces increased activity of alternative oxidase in fungus Phycomyces blakesleeanus
(Springer, New York, 2011)
Alongside classical, cytochrome respiratory pathway, Phycomyces
blakesleeanus possess alternative, cyanideresistant
respiration (CRR) facilitated by alternative oxidase
(AOX). In order to study role of oxygen in regulation ...
