Opis:
In relation to the scantiness of stores and the constantly increasing demand for energy, societies are forced to seek alternative energy sources. Biofuels that is fuels produced of biomass are one of them. The most important biofuels are bioethanol (produced from sugar cultivations and cereal crops, used with petrol) and biodiesel (ester produced mainly of vegetable oils; serves as the substitute or the addition to diesel). The esters of vegetable oils production requires using appropriate apparatus which enables to produce esters with parameters defined in very exacting legal norms about the quality of such fuel. In the paper were described results examining the quality of esters and mineral oils made with the use highly specialist, new generation 's apparatus which fulfll the conditions defining in the relevant norm. Results of those surveys are showing that using simple methods in production such biofuel doesn 't let for getting the product with parameters defined by the law. Applying fuel with lowered standard parameters influences on observed cases of improper functioning of fuel apparatus in engines with self-ignition, mainly in case of high pressure systems (e.g. Common Rail).

Opis:
Yield and quality of carrot seed were not affected by the mother root size used. However, the umbel position had significant influence on all the parameters used to evaluate the seed yield and quality except seed water content, which gave no significant response to the umbel order. Primary umbels resulted in better seed quality followed by the secondary umbels and whole plant, while tertiary umbels gave poor quality seed. All the seed yield and quality parameters studied also differed significantly for the interaction between mother root size and umbel order. Growth and yield of resulting roots were also not affected by the mother root size but were significantly influenced by the umbel order and its interaction with root size, indicating the supremacy of primary and secondary umbels on whole plant and tertiary umbels.

Opis:
Black mold and green mold caused by Alternaria alternata and Penicillium digitatum, re- spectively, are the most important decay pathogens of tomato fruits during storage. Our research was aimed to control tomato phytopathogenic fungi A. alternata and P. digitatum in vitro and in vivo by using natural nanomaterials rosmarinic acid (RA-NPs) at concentra- tions of 0.3 and 0.6 mM, glycyrrhizic acid (GA-NPs) and glycyrrhizic acid ammounium salt (GAS-NPs) (0.1–0.2 mM). Characterizations of the tested nanoparticles were carried out by using dynamic light scattering which revealed that synthesized nanoparticles had particle sizes of less than 100 nm. In vitro studies revealed that the three tested nanopar- ticles reduced the growth of A. alternata and P. digitatum. Glycyrrhizic acid nanoparticles were the most effective in reducing the growth of the two tested pathogens followed by RA-NPs at 0.6 mM. Observations of A. alternata and P. digitatum by scanning electron microscopy (SEM) showed severe damage in the hyphae and deformities in the conidia due to the effect of the tested nanoparticles. In vivo results showed that, dipping tomato fruits as a post-harvest treatment in all of the tested nanoparticles at different concentrations, then stored at 10 ± 1°C and 90–95% relative humidity (RH) for 20 days greatly reduced the disease severity of infected fruits with the two tested pathogens. GA-NPs at 0.2 mM signifi- cantly reduced the development of black mold rot on tomato fruits. RA-NPs at 0.6 mM had the best effect in controlling P. digitatum of all naturally and artificially inoculated tomato fruits. Also, individual treatments of tomato fruits with RA-NPs, GA-NPs and GAS-NPs significantly reduced postharvest losses of fruit since they delayed decay and maintained fruit quality characteristics such as fruit firmness, titratable acidity and total soluble solids during cold storage.

Opis:
Due to growing requirements concerning quality of products in food industry, it becomes important to introduce new, efficient, objective and repeatable automated methods of quality inspection. Agricultural products, such as cereal grains, are particularly difficult for automated inspection. This paper presents the results of experimental studies on the development of automated methods of manipulation and image acquisition of cereals, which can be used in machine vision systems for quality evaluation. Experimental studies were carried out on samples of brewing barley. The proof-of-concept evaluation of several methods was performed, on the basis of which the solution was chosen, based on the interaction of the screw and vibration feeders and bilateral image acquisition on moving transparent surface.

Opis:
Introduction and aim. Gifted children are defined as extraordinary children due to their high level of intelligence and specific skills. This study aimed to examine gifted children and their peers perceived parental attitudes, quality of life (QoL), and psychosocial problems. Material and methods. The study sample consisted of two groups: (1) gifted children (study group) and their parents and (2) peers (control group) and their parents. Data were collected using a descriptive characteristics form, the parental attitude scale (PAS), the pictorial pediatric symptom checklist (PPSC) and the pediatric quality of life inventory (PedsQL). Results. Both groups were similar in terms of age, gender and grade level. It was mostly the mothers who completed the data collection forms. The study and control groups had a mean PAS score of 94.18±0.738 and 99.31±0.798, respectively and a mean PPSC score of 16.11±0.475 and 16.76±0.480, respectively. The study and control groups had a mean QLS score of 83.19±0.70 and 80.28±0.83, respectively. There was a weak positive correlation between the PAS and PPSC scores (r=0.92; p<0.166). Conclusion. It is recommended that parental attitudes and their effects on children’s psychosocial status and QoL be monitored and that parents be supported. Parental attitudes and a child’s psychosocial and behavioral problems and QoL levels should be assessed to by health professionals be able to improve the well-being of both children and their parents.

Opis:
Art therapy is a field of activity with both practical and theoretical foundations although the latter are not precisely defined. Management and quality sciences, as well as economics, include management in the healthcare sector as one of their areas of interest. Despite a wealth of literature on the subject of management in healthcare, no in-depth research on art therapy as a specific form of delivery of the therapeutic process has been conducted so far. The aim of this article is to identify potential areas for further interdisciplinary research linking the field of management and quality with health sciences and education sciences (bearing in mind that art therapy is not a separate, autonomous scientific discipline). In order to achieve this we conducted a comparative analysis of selected concepts of management and quality sciences with the scope of the subject matter of art therapy, and as a qualitative method of literature review we chose the deductive method. The outcome of the study is the development of a proposed set of areas for further interdisciplinary research linking management and quality sciences with the sciences that include art therapy. The research findings presented here highlight numerous areas of overlap between art therapy and management and quality sciences, which hold potential for application in art therapy practice and theory.

Opis:
The result of human activity is polluting the soil and water. Based on the results of heavy metals studies it can be stated that the level of contamination of soil and water in urban areas is not high. This image is changing after taking into account other types of pollution. Besides some heavy metal contamination urban areas are contaminated with petroleum. Contamination of oil derivatives has a significant impact on the soil and water environment. In addition, some petroleum substances, such as petrol, have high vapour pressure. This causes a displacement of soil air from the vadose zone through the hydrocarbon gases, which creates a risk of explosion, especially in urban areas. This paper describes the pollution of ground-water oil derivatives in an urban area on the example of an oil filling station, operated for several years. In order to assess the condition of soil, 90 soil samples from different depths and 20 samples of groundwater were taken. Samples were taken for laboratory oil content tests. Using a computer program, a map of quality standards exceedances of soil and groundwater at the oil filling station and its vicinity was created. Results of laboratory tests of water samples are presented in tables and based on them, the classification of the underground water quality was made. Results of this study indicate a significant pollution of soil and groundwater exceeding the applicable standards. Condition of the soil and the quality of underground water in the oil filling station indicate the necessity of reparation.
