Mad cow disease first appeared in the 80's of last century and has gradually spread in series to high breeding countries, incurring major breeding and economic loses. In June of 2001, the disease was first doccumented in the Czech Republic and by year end 2006, there were discovered 26 cases. In accordance to the broader conception of the Common agricultural policy od the European Union, whose one pillar is pillar in the protection of agricultural industry, the European Union has paid breeders in particular EU states with financial compensation, which are the boundaries of the EU budget. For this purpose, there was established in the Czech Republic legal assignment for the distribution of this compensation, and this is reflected in act No. 166/1999, veterinary act and act No. 147/2006. Financial compensation will be paid by the Czech Republic's Minister of finance after the proposed approval by the Minister of Agriculture and the State Veterinary Administration. Submitted work will deal the majority of compensation to breeders with the occurence of BSE in breeding cattle and with regards to their disbursement.

This article deals with the change of mechanical properties of the Spruce wood (Picea abies L. Karst.) which was exposed to the attack of the wood-destroying fungus Serpula lacrymans Schröter.
An activity of the wood-destroying fungus has negattive effect on the wood and its properties. Growth of the wood-destroying fungus causes degradation of the chemical components of wood. Due to this the mechanical properties are changed and strength of the degraded wood is decreasing with extend of the activity time of the wood-destroying fungus. Together with this Serpula lacrymans Schröter causes the weight-shortage.
For tests in this article have been chosen the times of one, two and three months of the wood-destroying fungus attack. And then have been established weight-shortage and determined the strength of the degraded wood with Serpula lacrymans Schröter.

NIR spectroscopy making use of a near infrared spectrum offers wide using in a food quality control. This quick method allows the measuring of numerous samples with minimal usage of chemicals. Due this fact it is also used in quantitative analyses of milk composition. In this study we observed an impact of different temperatures of cow's milk samples on measuring exactness. The milk samples were taken from separate dairy cows and immediately refrigerated to 6-8 °C. Until the analysis the samples were deposited in the refrigerator. Just before the analysis on FT NIR spectrometer they were warmed to 40 °C and then cooled down in water bath to the temperatures 20 °C, 21 °C, 23 °C and 25 °C. Afterwards the samples were measured on Petri dish in reflectance mode with resolution 8 and number of scans 100. The spectres of samples were evaluated using calibration models for determination of solids and contents of proteins, fat and lactose. Observed measures were statistically compared within separate temperatures in relation to standard temperature 20 °C.

Permeability of wood is a wood property which strongly affects a process of drying wood, as well as steaming, boiling and wood impregnation. The low permeability of the most industry treated wood causes investigating the ways which increase the permeability of wood. The one of the considered methods is drying of wood with the aid microwave radiation which causes rotation and friction of water molecules, thus the temperature and the pressure inside the wood are growing up. As a result of raised pressure are crackled cell walls which makes the wood structure more permeable in transverse direction, but in longitudinal direction the wood speciemens treated with microwave radiation don't analyse differences in the permeability in comparison with unmodified wood.

Biosensors are analytical devices that transforms chemical information, ranging from the concentration of a specific sample component to total composition analysis, into an analytical signal and that utilizes a biochemical mechanism for the chemical recognition. The complexity of biosensor construction and generation of measured signal requires the development of new method for signal evaluation and its possible defects recognition. A new method based on artificial neural networks (ANN) was developed for recognition of characteristic behavior of signals joined with malfunction of sensor. New algorithm uses unsupervised Kohonen self-organizing neural networks. The work with ANN has two phases - adaptation and prediction. During the adaptation step the classification model is build. Measured data form groups after projection into two-dimensional space based on theirs similarity. After identification of these groups and establishing the connection with signal disorders ANN can be used for evaluation of newly measured signals. This algorithm was successfully applied for 540 signal classification obtained from immobilized acetylcholinesterase biosensor measurement of organophosphate and carbamate pesticides in vegetables, fruits, spices, potatoes and soil samples. From six different signal defects were successfully classified four - low response after substrate addition, equilibration at high values, slow equilibration after substrate addition respectively low sensitivity on syntostigmine.

The paper presents the resisitance of wood against a pilot flame. The fire has negative effect on the wood and its properties. The fire and its high temperature cause a degradation of chemical components of wood. Hence the physical properties are changed and strength of the wood is decreased. The combustion velocity and the loss weight depend on the material's thickness. For tests have been chosen groups of samples with thickness of 5, 10, 15 and 20 mm.
The result of submitted work is a time estimation of the fire penetration and an observation of weight losses coupled with visual changes observation of degraded samples. It have been established that with an action of the pilot flame the needed time to fire penetration is rising with rising material's thickness and at the same time the cumbustion velocity is decreasing.

Our work deals with a possibility of determining basic composition (fat, true protein, casein, lactose and somatic cells) of goat's milk Fourier transform near-infrared spectroscopy (FT NIR). Samples of milk were warmed to 40 °C, agitated, cooled to 20 °C, transferred to Petri dishes and analysed by reference methods and by FT NIR in reflectance mode. The measured area was spaced by a metallic mirror. Statistically significant differences between the reference values and the calculated values of NIR were not found (p = 0.05). Very high correlation coefficients were determined for goat's milk: fat 0.907, protein 0.989, casein 0.890 and lactose 0.981. The study showed that NIRS method, when samples of milk are measured on Petri dishes, is a useful technique for the prediction of fat, true protein, casein and lactose in goat's milk. Results of calibration for somatic cells are not accurate (correlation coefficients of calibration 0,885 and correlation coefficients of validation 0.566).

Poppy seed (Papaver somniferum L.) is an annual autumn or spring plant. This crop is cultivated generally for seed which is used as a foodstuff in food processing industry. The biological efficacy of different tested active ingredients (lambda-cyhalothrin, bifenthrin, aplha-cypermethrin, DE-225 and combination chlorpyrifos + cypermethrin) on poppy weevil (Stenocarus ruficornis S.) was evaluated in comparison with reference active ingredient (carbofuran) used as a standard treatment. The active ingredients were applied against the mentioned pest once in the season and were used in doses which were similar to those used against stem weevils in winter oil seed rape. Reference active ingredient was used in the dose which was authorised in the Czech Republic as standard ones against the poppy weevil. All active ingredients revealed efficacy which was measured (as a size of injuries) both on leaves and roots. Two trials were performed in 2001-2002 in which efficacy and selectivity were assessed.

Brewing is a very important part of the food industry with a successful tradition. Beer, brewer's malt and hops are important for export too. The situation in the beer market is changing dramatically at this time. Smaller local breweries are fighting with big competitors for the first time through expansion and innovation of the production line. Brewing development will be probably the same as in another European states, where are twenty big breweries to a thousand small ones. The strategy of Czech beer production is focused on the traditional production of classic Czech beer. For small breweries there are big opportunities in beer tourism, beer path building, brewery sight-seeing and brewery festivals for example.
This paper describes a particular firm's activities with using Porter's value chain and an analysis of its financial situation. In final part the Strength and Weakness analysis of the company Pivovar a sodovkárna Jihlava, a. s. is done and on the basis of the results are defined the appropriate advices.
During the recent period of time there have been many researchers from the FBE MUAF in Brno, who focused on the analysis of the food company's internal environment, e.g. Bečvářová (2005); Duda (2006, 2007); Jánský (2002, 2005); Syrovátka (2000); Veselská (2005); Zrůst and Pyšný (2007); Živělová a kol. (2004). The research on trade in food is solved firstly by Presová and Tvrdoň (2005).

In a small-plot trial with potatoes were applied increasing doses of selenium to the soil (0, 12, 24, 48 and 72 kg Se.ha^-1) and after harvest were explored the content of selenium, phosphorus and sulphur in raw tubers and in the tops. The trials were conducted in two localities - Žabčice and Valečov using the semi-early variety Ditta. Selenium was applied to the soil in the form of sodium selenite before planting the potatoes. Chemical analyses discovered that with the applied dose the level of selenium increased in both tubers and tops and that the correlation between the applied selenium dose and its content in tubers and tops was significant (α < 0.05) and positive (r = 0.885 and r = 0.908, respectively). With an increasing dose of selenium the reduction in the level of sulphur in the tops (r = -0.872, α < 0.05) was statistically significant. In both localities the range of the sulphur levels in tubers was very narrow, i.e. 0.16-0.18%, and the effect of the selenium dose was not significant. The phosphorus content in tubers and tops did not change significantly after application of a dose of up to 48 kg Se.ha^-1. With the highest dose of selenium the content of phosphorus in both tops and tubers decreased significantly.

In the food industry, phosphates, polyphosphates and their salts are used, for example, as emulsifying agents in the production of processed cheese. The inhibitory effects of three commercially available phosphates and polyphosphates differing in their chain length (690, S9 and HBS) were tested on a set of 15 gram-positive or gram-negative CCM (Czech Collection of Microorganisms) strains and on 12 bacterial strains isolated from processed cheeses. Five different concentrations of each phosphate were chosen (0.1, 0.2, 0.3, 0.4 and 0.5% w/v) in order to observe the inhibitory effects of the phosphate salts on the growth of the microorganisms tested. Sensitivity of the individual bacterial strains to phosphates was observed of a liquid cultivation medium which was supplemented with applied salts. Subsequently, the growth in cells was determined by measuring optical density at a wavelength of 600 nm. According to the results, 690 and S9 phosphates, containing mainly orthophosphates, diphosphates (pyrophosphates) and short-chain polyphosphates, do not have a significant inhibitory effect on the growth of the tested bacteria. Significant inhibitory effects were observed only in HBS salt (a mixture of long-chain polyphosphates), which showed antibacterial effects on all gram-positive bacteria tested (both the CCM strains and those isolated from processed cheeses). The antibacterial effect of phosphates on gram-positive microorganisms is growing with the increasing length of the polyphosphate chain. This study has not proved a significant effect of the phosphates tested on the growth of gram-negative bacteria used.

Providing employee benefits is a form of rewarding employees just for the fact that they are employees of the organization. The aim of paper was to find out, whether there exists a relation between the gender of respondents and their answers. It came from certain premises of research results, which were fulfilled. It was found that not providing employee benefits is not a reason for termination of the employment and search for a new job (86 % respondents). Employees (more than 80 %) prefer the possibility to choose between employee benefits, and employers should react to this information through defining rules of choice between the possible benefits. So far, employees of these firms cannot choose employee benefits they would want. Answers (more than 60 %) of employees related to whether they prefer wage increasing or expansion of employee benefits proved the premise and previous studies of the author, where a high preference of wage increase to offers of employee benefits was found. As confirmed by the research, answers of respondents are not dependent on gender of respondents.

We focused on tomatoes for industrial processing due to its economical importance for its lycopene content. The objective of our research is to find the variation of lycopene content in tomato fruits depending upon the length of after harvest storage and thermic treatment, which is inevitable when being industrialy processed. From the point of view of nutritional qualities the most relevant contentual substance of tomatos are carotenoids, included lycopene.
At average for tree following experimental years we learnt significant differences regarding the content of lycopene and the length of storage of tomato fruits. Immediately after the harvest and proccesing tomato fruits contained, at average for tree years, 103.24 mg of lycopene. After 14 days the content of lycopene declined to 46.76 mg.kg^-1 of fresh mass. After 30 days the average value dropped to 29.26 mg.kg^-1. This fact comfirms that boiling respectively thermic treatment increases the content of lycopene in tomato fruits, particulary in our experiment to the value 83.33 mg.kg^-1. At varieties Ladislav, Peto 86, Prémium, Salus the content of lycopene has even risen in comparison with its content up to 48 hours after the harvest. Tomato (Lycopersicon esculentum L.) belongs to the most signifficant vegetable varieties either for its exploitation in processing industry as well as for its nutritional value with extraordinary beneficial effect for human organism.
Although the content of lycopene is genetically stable attribute, its content in our experiment ranged from 45.39 mg.kg^-1 (Prémium variety) to 77.98 mg.kg^-1 (Zámčan variety), which are significant differences.

This paper is devoted to the possibilities of Economic Value Added index usage in the conditions of Czech food-processing industry and is trying to provide independent empirical evidence on the indicator's qualities. The EVA proponents attach to it a superiority compared to other common performance measures. The aim of this article is to investigate the relationship between Economic Value Added, traditional performance measures (ROA and ROE) and ability of creation of shareholder wealth for food-processing firms in the Czech Republic. The way of intended comparison is not dissimilar to the main world studies, which are quoted in this paper. A critical point of the EVA's application in the conditions of Czech economy is a lack of good quality information from capital market, which at the same time, serve as an exogenous criterion for assessing the quality of the examined measures in the mentioned studies. In the absence of quality capital market information, a criterion for assessing the information content of performance measures suitable for conditions of Czech economy is developed in this paper. This also shows how to circumvent the handicap of the available data.
The intent of this article is fulfilled by providing a simple regression test of the hypothesis, that the EVA measure is more associated with improved shareholder wealth than traditional performance measures ROA and ROE. The results of regression analysis show higher quality information content of EVA indicator in the relationship to the ability of shareholder wealth creation than traditional performance measures. This fact supports the tested hypothesis as well as the conclusions of corporate finance theory, that from the theoretical point of view EVA is seen as a superior performance metric.

In 2004 and 2005 we explored the effect of graded doses of selenium in the soil (0, 12, 24, 48 and 72 kg Se.ha^-1) on yield-forming parameters (total plant weight, number of stems per hill, number of tubers per hill and hectare yields) in two varieties of potatoes of different vegetation periods. The content of selenium as an important anti-oxidant was monitored in potato tubers and tops. Selenium in the form of sodium selenite was applied in the respective doses into the soil before planting the potatoes. Samples for growth and chemical analyses were taken after 90 and 99 days of vegetation (variety Karin and Ditta, respectively). Increasing doses of selenium had a negative effect on most of the yield-forming parameters. With an increasing dose of Se the hectare yields as well as the number of tubers in the hill and total weight of the plant decreased. Chemical analyses were performed using the AAS method and showed that the concentration of selenium in the individual parts of the potato plant increased with increasing Se doses in the soil. The content of selenium in tubers of the variant Se₇₂ (4.13 mg Se.kg^-1 of dry matter) increased as much as 20 times when compared to the control (0.22 mg Se.kg^-1 of dry matter).

Besides chemical and microbial parameters of white yoghurts, other quality indexes are also one of sensorial features. Products introduced in market have to fulfil set criteria. One of them is minimum endurance time. Of course, even during this period certain sensorial changes appear which can influence customer choice at repetitional purchase. Samples of white yoghurts of different fat proportion from different producers were evaluated by qualified staff. Samples were given to the lab right from the producer and assessed on their production day. Changes of particular descriptors were monitored depending on length of storage and fat proportion during their minimum endurance time. Finally, results were evaluated and graphically expressed.
Almost at all monitored yoghurts their sensorical features got worsed. The most significant change was detected at those samples, where dried whey used for their production. At these ones whey was releasing, thus the yoghurts were of different taste. The best evaluation got white yoghurt (1) during all period of expiration containing just milk and vital yoghurt culture.

Our work deals with a possibility of determination of basic composition (dry matter, fat, protein, casein, lactose and urea nitrogen) of ewe's milk and colostrum by FT NIR spectroscopy. Samples of milk were warmed to 40 °C, agitated, cooled to 20 °C, transferred into Petri dishes and analysed by reference methods and by FT NIR in reflectance mode. The measured area was spaced by a metallic mirror. Statistically significant differences between the reference values and the calculated values of NIR were not found (p=0.05). Results of calibration for ewe's milk determined the highest correlation coefficients: dry matter 0.983, fat 0.989, true protein 0.997, casein 0.977, lactose 0.980 and urea nitrogen 0.973. The study showed that NIRS method, when samples of milk are measured on Petri dishes, is a useful technique for the prediction of dry matter, fat, protein and casein in ewe's milk.

With the help of a constitution diagram Fe - Fe₃C, a diagram TTT and vertical structural diagram of the authors' own construction it is determined that the relative amount of products in steel occurs in any temperature of isothermal disintegration of austenite. Making use of camouflage it is enabled to set bouth structural and phasic composition of alloy at the same time. In case of use of appropriate animating software (e.c. Macromedia Flash) it is possible to practise this quantification on steel of any chemical composition.

Business subjects in any national economy perform activities results of which are products, services or goods directly distributed to the market network. Volume of products differs according to the level of operational facilities, number of producers and the level of their facilities. Based on the development of information technology, there arise new specialization fields and new ranges of goods. Classification criteria are developed to qualify level of production and for enlistment of a firm to a particular branch. Currently the criteria of production classification are being developed. The understanding of these principles is particularly important on the bachelor level of the specialization Trade Management, where students are getting acquainted with the characteristics of goods, creative and degradation influences on utility, etc. Students are encouraged to understand how the quality and criteria mentioned above influence market prices. Teaching emphasis is put on the complexity of food assortment and the knowledge of Czech and EU legalislation relating to hygienic aspects and health quality of production, processing, and selling of food products. This complex procedure enables to obtain an overall survey of the origin of particular products, their catering, and sales. This means that the students obtain an idea about the complexity of relations existing among the origin of products, their sales and their consumption.

The baking industry is one of the most important parts of the Czech food processing industry.
The Czech baking industry has a bigger price differential compared to other Europe Union bakers than occurs with any other industry. Therefore the Czech government has integrated plans to improve this competitive advantage.
The up-to-date trends are compared with the main European bakery producers and consumers-Germany in this paper. The research is focused on the analysis of the basic factors of supply and demand in the bakery markets of both these countries.
During the recent period of time there have been many researchers from the FBE MUAF in Brno, who focused on the environment in the branch, e.g. Bečvářová (2005), Černíková and Žufan (2004); Chládková and Kudová (2004), Tomšík and Chládková (2005), Syrovátka (2000), Veselská (2005). The research on trade in food is solved firstly by Presová and Tvrdoň (2005).

Surface treatment of zinc galvanized steel is carried out usually using chromate based baths. These baths are used for improvement of the corrosion resistance and enhancement of the chemical adhesion of organic coatings. Anticorrosive effects of the chromium conversion coatings were not completely exceeded yet by another kind of passivation. Toxicity of Cr^VI is a basic problem of chromate conversion coats. This paper presents the main results and conclusions of experimental study on zinc conversion layers based on vanadates, using a good Cr^VI bath as reference. Anticorrosive mechanisms were compared by the corrosion tests in saline cabinet. Inhibition effects were characterized by scanning electron microscopy, by X-ray dispersive spectrometry (EDS) associated X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy.

The aim of this contribution is to be able to used triticale in distilling industry. Four triticale varieties were grown during 2003-2005. Trials were situated in four different locations of the Czech Republic - Staňkov, Hradec nad Svitavou Krásné údolí and Libějovice. There were used varieties Kolor, Presto, Modus and Disko. The alcoholic yield, protein content and starch content were determined. The technical enzymes Termamyl SC and SAN Extra L. were used into laboratory fermenting tests for saccharification starch. Reached alcoholic yields move between 37-46 la. The highest alcoholic yield (average three years and four locations) was estimated by variety Modus (41.19 la/100 kg. in dry matter), the lowest variety Kolor (40.08 la/100 kg in dry matter). The location Hradec n/Svitavou (41.68 la) and Krásné Údolí were favourable, the year 2005 (41.48 la) was the most positive.
The highest starch content is into positive correlation with alcoholic yield (r = 0.396) and negative with protein content (r = -0.327). The results were pointed out that triticale makes it suitable for in the distilling industry.

The paper is focused on characteristic of winegrowing and wine-production in New Zealand, country, which together with Australia, Chile, Argentina, California, and South Africa belongs to the countries of the so-called New World, and these countries become very important producers of wine in the world. Thus, they become a part of the competitive environment in winegrowing and wine-production of the Czech Republic. One of the necessary premises for determination of the competitive position is a detailed analysis of competition. This was also dealt with by Černíková, Žufan (2004), Duda (2004), Hrabalová (2004), Kudová (2005), Lišková (2004), Tomšík, Chládková (2005).
Winegrowing regions of New Zealand are located in the areas of higher average temperature than the European regions. This climate suits mostly for blue grapes. The beginning of winegrowing is connected with the name of a Scot James Busby, who produced the first wine in 1836. In the middle of the 19th century, two winegrowing regions were known worldwide - Auckland, and Hawkes Bay. Currently, there are 14 winegrowing regions with the area of 18.112 ha of fertile vineyards, and in 2006 the area of fertile vineyards should grow by 15% (to 20.877 ha). The area with the largest area of vineyards is Marlbourough (8.194 ha), where there are 275 growers of vine being processed by 84 wine-producers. The total number of wine producers in New Zealand in 2004 was 471, only four of them producing more than 2 mil. l (the biggest company is Montana).
The harvest in 2004 was 162.100 tons of grapes, in New Zealand, which means 123% growth in comparison with 1995. The highest growth of harvested grapes was in the region of Hawkes Bay - by 181%. Wine production is changing from year to year, but for the 2004 a growth is expected due to the volume of harvested grapes. The exports of New Zealand's wine have grown almost 3.5-times in the period of 1995-2003 in terms of its volume, and recounting it from NZ$ to €, the growth was even 6.8-times higher. The exports of New Zealand wine are continuously growing - the highest amount from 1995 was exported to Great Britain (25.756 mil. l). The exports to the Czech Republic have grown almost 15-times in the period of 1999-2003, with a prevalence of the white wine. The average price of one litre of wine imported to the Czech Republic in 2003 was € 6.7. Imports of wine to New Zealand have grown by 74% in the period of 1995-2003. Most of the imports are realized from Australia (73% of the total imports in 2004). Within the monitored period, there was a change in the prevailing type of the imported wine - from a prevalence of the white wine in 1999 to the currently prevailing red wine (growth by 17% in 2003). Consumption of alcohol have grown by 6.5% in the period of 1998-2003, most of which was caused by the growing consumption drinks with the alcohol content of more than 23% (growth by 60.8%).
The paper is a part of solution of the grant focused on analysis and formulation of further development of winegrowing and wine-production in the Czech Republic provided by the Ministry of Agriculture (No. QF 3276), and it is also a part of solution of the research plan of the Faculty of Business and Economics, MUAF in Brno (No. MSM 6215648904).

This paper aims to contribute to deeper knowledge of the economics of the beer commodity chain, focused on the formation of the market structure and its interactions with the price development within analysed commodity chain. The results of the economic analysis have proved, that czech brewery is high concentrated and that between concentration ratio and breweries's margin exists a positive interdependence.

In the experiment, the effect of chemical (A) and biological (B) additiva on the fermentation quality of climper high moisture maize grain corn was examined, compared with the untreated control (K). The chemical means contained propionic, formic and benzoic acids and ammonium formate as effective substances. As effective substances of bacterial water-soluble inoculants, selected were bacterial strains of Propionibacterium shermanii JS and Lactobacillus casei LC-705. Both conservative preservatives were added equally to the ensilaged material. The addition of chemical additivum under conditions of our experiment increased statistically significantly (P

Rural tourism has come to occupy a prominent position in the debate about rural restructuring in all OECD countries, partly because of demand changes which favour rural tourism and partly because rural agencies recognise a need to provide economic activities with potential for growth in a rural economy in which traditional providers of rural employment (such as agriculture) have been shedding labour at a rapid rate.
Well-designed strategy is essential to its success in impacting on the rural economy. The structures for collaboration and co-operation must be developed and combined with a process of education and training. Co-operative effort must be effective and sustainable. The tourism related businesses should not be isolated from the larger community and its issues.
The principal motivation for a community, business or region to serve tourists is generally economic. An individual business is interested primarily in its own revenues and costs, while a community or region is concerned with tourism's overall contribution to the economy, as well as social, fiscal and environmental impacts. A good understanding of tourism's economic impacts is therefore important for the tourism industry, government officials, and the community as a whole.
The principal objective of the study, that is reported here, was to determine the potential income of farmers from the provision of agro-tourism services. First, the paper reviews selected results of the visitor spending survey in alternative types of rural tourism of the region Southeast (Czech Republic); second the direct economic benefit of the agro-tourism in this region is estimated, and finally, critical factors reducing the effectiveness of agro-tourism as a rural development instrument are drawn.

The rheological behaviour of egg yolk after different storage periods and temperatures was investigated using rotational viscometer. The eggs were stored for 1, 2, 3, 4 and 8 weeks at constant temperatures: 4 °C, 8 °C, 12 °C and 16 °C. The apparent viscosity was measured as a function of shear rate. For given shearing rate, the viscosity was measured in dependence on shearing time. The decrease of viscosity with storage time is attributed to the balance of different osmotic pressure from yolk and albumen of fresh egg. The yolk (with higher dry matter then albumen) absorbs water from albumen through vitelline membrane. It was found that yolk samples exhibited shear-thinning and thixotropic behaviour. The shear-thinning behaviour was fitted well into simple models. The resting of sample at room temperature caused increase of viscosity. This effect is explained by drying off of testing yolk, the regeneration of yolk structures and changing chemical composition during resting. The time-dependant viscosity decreased rapidly with time and at lower share rates reached an equilibrium stage. The time-dependant viscosity was also found to decrease with storage time. The value of pH was changed (increased) during storing. No clear dependence between pH value and viscosity was confirmed.

Changes in the perception of economic growth within the context of sustainable development lead to the broadly defined concept of further development of all industries, while agriculture plays qualitatively new role in this concept. Agriculture is not any more viewed only as an industry ensuring nutrition of population, but also its non-production benefit has growing importance. There is growing importance of the concept of multifunctionality of agriculture both in the Czech Republic and in the whole European Union, where agriculture historically played an important role in landscape formation and determined the development of social structures, while these aspects have growing importance for formulating of agricultural policies. Multifunctionality reflects the fact, that agriculture produces many food and non-food commodities, while some of them have the character of externalities and public goods.
One of important conditions of efficient conception of agricultural policy is the answer on the question, what is the impact of growing trade liberalization on social welfare, respectively welfare of producers and consumers, if there are positive agricultural externalities. The analysis brings comparison in welfare development when externalities are internalized and when they are not. There are important consequences for social welfare, if state does not evaluate extra-production benefit of agriculture in a proper way.
For the distribution analysis of benefits and costs of agricultural trade liberalization in presence of positive externalities connected with agricultural production, e.g. the analysis of impacts on consumers, producers and social welfare, is used traditional international trade model.
Under the present tendency to liberalization of world agricultural markets there should be an effort of policy makers to internalise agricultural externalities. If there are agricultural industries, which are net exporters and at the same time produce positive agricultural externalities, trade liberalization brings additional increase of social welfare, connected with increased production of given agricultural commodity and at the same time increased production of positive agricultural externality. Growth of social welfare will be higher if positive agricultural externality will be internalised.
For agricultural industries with positive externalities which are net importers, the change of social welfare brought by trade liberalization is not obvious. It depends on concrete character of cost and demand curves. However in any case, the social welfare will be higher with internalised externality that without internalization.

Vertical Sauver's diagrams provide analogous information about specific alloys same as classical Sauver's diagram, the Tamman's diagram or cooling curve with the lever rule application. Particular animation programs like Macromedia Flash facilitate in construction of vertical diagrams and enable their fluent transformation depending on chemical constitution of alloys. Utilization of function masking enables monitoring of the phasic, structural and complex constitution of alloy in the course of different temperature at the same time. Unique structure description of the metal alloys extends knowledge in metallographic science.

The importance of convergence in foreign trade is mentioned in the theory of optimum currency from the very beginning. Also the OCA index incorporates two basic aspect of foreign trade. The territorial reorientation is always characteristic for new EU-members and this process was already accomplished by most of the new EU-members. The more developed associated countries are already at the level of EU-members. The commodity orientation is connected highly with the competitiveness and level of development of the whole economy and the shares of sophisticated product in exports reflect it. Hence the evaluation was concerned on the manufactured goods, SITC group 7-Machinery and transport equipment and the high-technology intensive products. From viewpoint of commodity structure the countries joining EU in 1995 are the most successful. They are closely followed by the other EU-members. The new EU-members of 2004 are lagged, the lag is getting wider with the rise of technology intensity. Only the Czech Republic and Hungary are able to compete with the older EU-members. The commodity convergence of EU countries is runs very dynamically in new members, the shares of other EU countries are almost constant. The results of intra-industry trade also reflect the lag in competitiveness of economies under transition. The transition countries are very heterogeneous in the intra-industry trade as well. The internal structure of transition countries is similar to result obtained when assessing the commodity structure.
