Development of analytical methods for speciation of organotin compounds in environmental samples using gas chromatography and mass spectrometry
Organotin compounds (OTCs) are the organometallic compounds with the most numerous applications. Today, it is more than 50 years of their intensive development and use. While they are highly useful chemicals they are also extremely toxic to a wide array of aquatic and terrestrial living organisms at very low concentrations. …
Contribution to understanding of the mechanism of amyloid fibril formation and its effects on the cell
The presence of insoluble amyloid aggregates in various human tissues correlates with the development of many human disorders (amyloidoses), including neurodegenerative diseases. Deposition of the aggregated misfolded proteins in the brain, where aggregates can be localized extracellularly or intracellularly, is the main characteristic of Alzheimer's, Parkinson's, Huntington's, prion diseases and …
Hydraulic load cells for measurement of small loads
This work deals with the design of a small kitchen appliance with a weighing function integrated into a control loop in order to prevent unbalanced movement of the appliance during operation. In this particular case, the weighing should be appropriate for larger amounts (up to 5 kg) of ingredients. The …
Uporaba dopolnjene resničnosti in brezžičnih senzorskih omrežij za podporo minimalno invazivni kirurgiji
Minimally invasive surgery is one of the most promising trends in medicine. Despite of its obvious advantages - the use of small incisions reducing trauma and risk of infection - it still represents a great challenge for the surgeon, as visual guidance and dexterity are severely impaired. In the case …
Handover in Heterogeneous Networks Using SIP Protocol
Over the last decade we have been witnessing rapid development of telecommunication networks and services, in particular in the filed of new wireless network technologies. On different markets users are able to communicate using different wireless technologies. The first two generation of mobile networks (i.e. NMT and GSM) were developed …
Test Infrastructure Design for ADC Cores in System-on-Chip
With the advent of System-on-Chip (SoC), intense research efforts are being carried out in order to find efficient practical solutions for testing deeply embedded, mixed-signal cores. Due to restricted access, a built-in self-test (BIST) of mixed-signal cores is in many cases a preferred alternative to a conventional test using external …
Plasma treatment of polymers for biomedical applications
Vascular grafts made of polyethyleneterephthalate (PET) polymers have successfully replaced large-diameter blood vessels, but the long-term performance of small-diameter (< 6 mm) vascular grafts is still disappointing. The main problem is insufficient biocompatibility of polymer surface with blood, which causes complications after implementation; such as thrombosis or restenosis. These complications …
Speciation of aluminium in human serum by CIM® (Convective Interaction Media) monolithic chromatography and mass spectrometry
The toxicity, biological availability and mobility of aluminium (Al) depend on its chemical form. In order to understand toxicity and transport of Al in human body it is important to identify and quantify Al species present in human serum. This led to the development of sensitive and selective analytical methods …
Automatic text parsing aided by clause splitting and intra-clausal coordination detection
In language technologies, syntactic parsing represents one of the possible intermediate steps of text analysis in the applications such as machine translation, information extraction, question answering, etc. Syntactic trees are often used to demonstrate the structure of text. In the last decades, the dependency framework became a popular syntactic representation, …
