This study presents functional and nutritional properties of the tomatoes (Solanum lycopersicum L), an ideal source for health promoting compounds. In this paper eleven cultivars of tomatoes were studied that were grown in greenhouses in Oltenia (Romania), which were differentiated between them by shape, size and colour of the fruit. For biochemical determinations, fruit samples were collected at physiological maturity. It was determined the content in soluble dry matter, total dry matter, vitamin C, content in ma...

Cruciferous vegetables are rich source of phytochemicals which play an important role as a health-protecting factor. These compounds and enzymatic systems may combat oxidative stress in the human body by maintaining a balance between oxidants and antioxidants. This is particularly important because under oxidative stress excessive formation of reactive oxygen species (ROS) can damage biomolecules, such as DNA, proteins, lipids and carbohydrates, and lead to numerous disease conditions. The enzyme superoxide dismut...

Gridded climate data are valuable source of information that can be used in various fields of environmental studies. One of the example is dendroclimatological analysis, where climatic data are essential part of the study. These data are especially useful when there is a lack of weather station data for the study area, the available data are incomplete or their time span is insufficient. However the accuracy of gridded data can be sometimes questionable. In this study gridded data planned to use in dendroclimatolo...

The coal processing industry uses a various technology for the process control. Various devices and control systems there can be implemented.

The increasing number of cars contributes to the degradation of human living space. This phenomenon affects both urban as well as residential areas. The communication system of housing estates made in the second half of the twentieth century in Poland was not designed for such a large number of cars that it has to handle today. Many factors influenced the present appearance of the prefabricated multi-family houses. First of all the obligatory standards, which assumed nearly ten times smaller parking rate than we a...

The paper deals with the removal of hydrocarbons C10-C40 from the river sediment using flotation and bacterial leaching. Flotation, as a purely mineral processing method, was used to remove a large percentage of organic pollutants. Flotation has not been applied in the cleaning of organically contaminated soils and sediments in the Czech Republic so far. The flotation collecting agent was Montanol 551. The flotation results show that the method appears as very effective as dominant proportions of the pollutants pa...

Well logging is usually used for monitoring the technical condition of the wells. This means whether there is degradation of the casing (potential subsurface damage of well) or not and uncontrolled overflow behind casingпїЅs strings. Measurement is able to cover both the static state of change saturation and the dynamic process of the ongoing spill in the relevant horizon. Furthermore, if there are monitored overlying horizons because of gradual overflow and saturation of the storage gas caused untightness of well...

The application of REACH and LCA systems to the coal waste was presented in this paper. Recent years has brought a growth interest in environmental management systems, which could minimize the negative environmental impact of chemical substances. As a result of that process standards such as REACH and LCA have been developed. Both of those systems are based on different assumptions. LCA refers to the whole life cycle of particular product and in consequence is considered as so-called пїЅfrom cradle to graveпїЅ stu...

Recycled Concrete Aggregate is a material resulting from the crushing of concrete elements. Currently, as a result of increased demand for natural aggregates, artificial aggregates are sought as an alternative materials in civil engineering activities.

The paper presents the results of the California Bearing Ratio (CBR) and cyclic CBR (...

Currently, a great emphasis is put on the environment, energy intensity, and therefore on applications of the renewable energy sources (RES). Putting a large amount of RES into the modern distribution systems represents certain problems we can address, inter alia, the variable energy outputs of RES aggregated together, including their accumulation managed by respective energy management system (EMS). The result may be the optimization unit commitment of RES distributed in the micro-grids of a fictitious intelligen...

This paper presents a technique for the detection of elliptic objects connected with subsidence troughs in radar interferograms using the Hough transform. The generalized Hough transform to detect arbitrary shapes, including ellipses, requires a five-dimensional accumulator array, which occupies a very large part of the memory. For this reason, to overcome memory problems, a modified algorithm using a one-dimensional accumulator array was applied. This modification helped also to reduce the computation time. In th...

The chronometric geodesy is based on a relationship derived on the basis of the general theory of relativity, indicating a change of frequency and time at occurring change of potential. It is known that there is a possibility of using these relationships to determine geopotential changes, thus also height changes, by examining changes of clock rates in various places. From the formulas that describe this relationship, it can be estimated that at geopotential change by 1 m2/s2 (which corresponds to a height differe...

In Europe, the knowledge and measures regarding self-protection in case of emergency is very poor in general. Within the population, young people aged 7 пїЅ 12 require a special approach, as their knowledge and behavior is different from adults. Their perception of accidents and disasters needs to be educated through an efficient teaching program. Therefore, a first step in developing such a tailored education program is to assess the natural hazards in European countries, with a special focus on the hazards that ...

The majority of current water quality measurements are based on the traditional in-situ point sampling and laboratory analysis of the samples. This method, besides being time and financially more consuming than the remote sensing, also very often lacks a sufficient spatial and temporal resolution to adequately analyse and describe different phenomena (i.e. eutrophication). In this study, we have assessed the possibility to use air-borne hyperspectral remote sensing for mapping concentrations of different water qua...
