Fish is an important source of protein, iron and zinc - essential nutrients for child growth and development, a source of energy for adults, elderly. Omega-3 fatty acids found in different fish species help develop children’s brains, maintain flexibility in blood vessels and contribute to brain oxygenation by annihilating the destructive effe...

Access to spatial data and services constitutes an important basis for environmental policies for all public authorities and is therefore a central aspect of the Infrastructure for spatial information in the European Community. Since the Community institutions and bodies in most cases have to integrate and assess spatial information from all the Me...

The composting is one of the most effective recycling method of green waste. The presence of some heavy metals as Cr2+, Cu2+, Mg2+ and Zn2+ may influence the compost quality. Thus, by adding some components like manure the micronutrients and heavy metals regime suffer changes which might influence their bioavailability for plant uptake. The bioavai...

The technical state of the contact line and also the additional equipment in electric rail transport is very important for realizing the repairing and maintenance of the contact line. During its functioning, the pantograph motion must stay in standard limits. Present paper proposes a LabVIEW application which is able to track in real time the motio...

The brake pads are an important component in the braking system of automotive. Materials used for brake pads should have stable and reliable frictional and wear properties under varying conditions of load, velocity, temperature and high durability. These factors must be satisfied simultaneously which makes it difficult to select effective brake pad...

Shafts of electric locomotives are exposed to complex normal and tangential stresses during its exploitation. These stresses could have extremely high level producing the breakage of the shaft. It is well known that shafts have much longer service life than wheels. However, since the stresses in shaft’s material are high, it is possible to mi...

The presence of the heavy metals toxic compounds (CuSO4 5H2O, ZnSO4 7H2O and 3CdSO4 8H2O) in water and soil can be observed by their negative effects on the germination and growth process for different vegetable (barley, oat, maize) who are used for human and animal consumption. This paper it aims the determination of germination and growth inhibit...

An alternative and cost-effective solution to developing integrated PV system is to use hybrid photovoltaic/thermal (PV/T) solar system. The temperature of PV modules increases due to the absorbed solar radiation that is not converted into electricity, causing a decrease in their efficiency. In hybrid PV/T solar systems the reduction of PV module t...

Adopting the most appropriate technology for developing applications on an integrated software system for enterprises, may result in great savings both in cost and hours of work. This paper proposes a research study for the determination of a hierarchy between three SAP (System Applications and Products in Data Processing) technologies. The technol...

The quality of electric energy capture and also the equipment operational safety depend essentially of the technical state of the contact line (CL). The present method for determining the technical state of CL based on advance programming is no longer efficient, due to the faults which can occur into the not programmed areas. Therefore, they cannot...
