Effect of ingested nanofibers and nanoparticles on digestive gland epithelium of a model test organism
Engineered nanofibers and nanoparticles are recognized as capable of inducing cellular perturbations according to the oxidative stress paradigm or by interacting directly with biological membranes. A number of authors in their investigations with the nanofibres and nanoparticles has reported the ability of nanofibers and nanotparticle to cause the different damage …
Selenocompounds in selenium-enriched plants determined by spectrometric methods
Selenium (Se) has been demonstrated to be an essential trace element for maintenance of animal and human health. Se is incorporated into proteins to make selenoproteins, which are important antioxidant enzymes. The antioxidant properties of selenoproteins help to prevent cellular damage caused by radicals. Radicals are natural by-products of oxygen …
Occurrence, fate and removal of pharmaceutical residues in water treatment
The presence of pharmaceutical residues in surface waters is an emerging environmental issue that provides a new challenge to treatment systems for potable water, wastewater and water reuse. Their principle pathways into the sewerage system are twofold: first, after being administered to patients they are normally excreted as various metabolites …
Monitoring of the product quality in manufacturing industries
Unexpected production breakdowns and unpredictable defects in product quality remain critical problems in modern manufacturing systems. Usually occuring by no obvious exterior cause and often during periods of smooth production, they lead to production losses and reduced process availability, which results in lower profit rates. Conventional statistical methods of process …
Modular gene dynamics and network theory at mesoscopic scale
Complex dynamical systems are often modeled as networks, with nodes representing dynamical units which interact through the network’s links. Gene regulatory networks, responsible for the production of proteins inside a cell, are an example of system that can be described as a network of interacting genes. The behavior of a …
Dynamic Modeling of Climate Change Impacts of Greenhouse Gas Reduction with Renewable Energy in Kosovo
Atmospheric concentration of CO2 and other greenhouse gases (GHG) is higher than any time in the last 400000 years and growing faster than at any time in the past 18000 years. The high concentration of GHG generates radiative forcing that contributes to climate change. Energy production from fossil fuels has …
Mass Balance of Mercury in the Idrijca River Catchment
Mercury (Hg) pollution has been investigated in the area of the Idrija mercury mine, Slovenia, where the second largest mercury mine in the world operated for more then 500 years. Although the production of mercury at the Idrija mercury mine stopped in 1994, centuries of mining and ore processing operations …
Stigmergy as an Approach to Metaheuristic Optimization
Developing metaheuristics to solve optimization problems is a rapidly growing field of research. This is due to the importance of optimization problems in the scientific as well as the industrial world. The methods developed in this dissertation are based on stigmergy: a method of communication in emergent systems, where the …
