In this lecture we will give an overview about the aspects and traditions of distinction between original and derivative getting modes.
We will examine which of the getting modes can be looked at as „obviously” original and review how they affect the third party’s rights existing on property. This study makes it possible to explore the
ZigBee technology aims to completely satisfy the requirements set by precision agriculture, since this system makes it possible to collect data in an accurate and regular way. The cost of one module is rather favourable; therefore, damaged parts can be replaced quickly. Due to the modular structure, the system can be further developed easily. N...ew units can be quickly incorporated into the network without any difficulty.
The Limagrain maize hybrids in different maturity groups were examined at the Látókép Experimental Station of the Centre of Agricultural Sciences and Engineering, University of Debrecen on a calcareous chernozem soil with loam texture, between 2001 and 2007 in a multifactorial long-term field trial. Doses of fertilizers: 1 N:0.75 P2...b>O5:0.88 K2O fixed proportion of NPK doses. The basic dose of nitrogen is 30 kg ha-1. The application of fertilization was 1, 2, 3, 4, and 5 times more than the basic dose, beside of untreated control. The long-term field trial is performed in none irrigated and in irrigated version.
The goal of the study was to analyze the effect of precipitation (environment factor) in one hand, and to evaluate the effect of fertilization and irrigation (agrotechnical factors) on the yield of maize hybrids in different maturity groups in the other hand. At the same time I studied the effect of interaction of different factors on the yield of maize.
Analysis the yield of Limagrain hybrids revealed: the years considerably affected the level of the yield. In dry years the yield was 1.351 t ha-1 less, than in rainy years. As the effect of fertilization the yield increased, the statistically proved biggest increment was at level of 90 kg N ha-1. Evaluating the maturity groups, FAO 300 hybrids reached higher level of yield.
In non irrigated conditions in the average of the seven years 60 kg N ha-1 was sufficient to reach the maximum yield. The efficiency of fertilization on yield in irrigated version increased, 120 kg N ha-1 assured the reliable level of yield.
Without irrigation in comparison to the results of FAO 200 group, with the growth of FAO numbers the yield is increasing in all cases. The most significant increase was at FAO 300 (3.562 t ha-1). With irrigation the greatest difference in yield was in FAO 400 (+2.720 t ha-1) compared to FAO 200.
We planted containers plum rootstocks and cultivar combinations for irrigation and rootstocks experiment. We planted Cacanska lepo tica, Katinka, Jojo, Topfive, Toptaste, Topper plum cultivar on Mirobalan, St Julien A, St Julien GF 655/2, Wavit, Wangenheim, and Fereley rootstocks. Before budding we measured the trunk diameter on trees, than I c...ount the trunk cross area, we measured the high of trees, the high of crown, and the wide of crown, and counted the volume of crown from these data. We conclude the vigorous from the trunk cross area and the volume of crown. In the started growing less vigorous combinations look like Topfive/Wavit, Jojo/Mirobalan and Katinka/Mirobalan grafted on the basis trunk cross area and the volume of crown. In the vegetative period we measured the shoot growing on model branch every started of months. So we could determine the growing tendency. The smallest growing was Cacanska lepotika/Mirobalan.
In the flowering the grafted flowered in rich, excepted the Topfive cultivar on St Julien A, St Julien GF 655/2, and Fereley rootstocks, these didn’t flowered. The Topfive/Wavit combinations there were a richest flower.
In the harvest term we could pick up plum fruits from Topfive/Wavit combinations, and Cacanska lepotica, Jojo, Toptaste cultivar. And in addition the Topper cultivar was the highest yield on their all of rootstocks.
Fuelwood, and wood wastes provide almost half of the renewable energy production of the European Union. Enhancing the use of wood in renewable energy production has more constraint than wind- or solar energy. Forests in the EU member states are sustainably used, they are increasing both in terms of area, and growing stocks. There are possibilit...ies to enhance the fallings and use more fuelwood. Short rotation coppices could fulfill the long term demand for fuelwood; because these plantations surpass the dendromass yield of forests.
The study is going to reveal the role of landscape potential in spatial and rural development based on the analyses of scientific literature. The target area of the research is three micro regions in Hajdú-Bihar county. In addition to the analyses of scientific literature the study pays attention to the assay of local development concepts and...programmes. The conclusion of the study is that the analyses of landscape changes on micro regional level are obstructed by the lack of micro regional spatial development and substantive landscape plans.
Hungarian wine is not in such a bad position as it is considered. We have outstanding specialists and the country’s natural conditions are also proper. The level of Hungarian wone culture is comparatively low but is capable of progress. Hungarian Wine Marketing Non-profit Company helps public wine marketing to be really effective. The develop...ment of tourism in wine-growing regions and advertising would considerably promote the popularity of Hungarian wine.
The spatial structural position of Hajdúböszörmény (ease of access) and its economic and social endowments which are more favourable than those of its surroundings make the town more desirable as a target of migration. These endowments are rather advantageous on their own, but the specific settlement structure of the town results in the fac...t that concentrated, unmanageable and majorly segregated social crisis points have developed in some easily circumscribable parts of the settlement which could lead to a social explosion.
Last year intense rainfalls and moisture conditions were beneficial for the Fusarium sp. in Hungary. Fusarium strains decrease cereal quality (for example maize), furthermore may cause yield loss. Due to the toxin production, the fungi have a dangerous animal and human pathogen effect (Placinta et al., 1999).The effects of the Fusarium infectio...n and its mycotoxin production haven’t been perfectly eliminated. Fusariumgraminearum
is the most common agricultural pathogen in Hungary. The utilization of infected maize as an alternative biogas raw material may be an efficient and environmentally friendly disposal method. In this case, Fusarium-, and mycotoxin-content of the maize have to be analyzed as well as the impact of these factors’ on the biogas production process. Our experience was based on the raw material basis of a biogas plant. Different amount of Fusarium free and infected maize grits have been added to the regular raw material mixture. The detection of Fusarium fungi has been analyzed
in experimental digesters throughout the different stages of mesophilic digestion. In the biogas liquid end product the Fusarium was detected by breeding and by microscope. According to our results, the Fusarium sp. was not detectable in the liquid end product after 30 days.
The crisis of the hungarian agricultre is continuous since the ’80s. The compensation is made a dual farm system, which has created barriers to efficient agricultural production. It is confirmed by the economic indexes as well. But the most important natural resources of our country is still the land. Over the past 20 years, the government wa...s not able to work out strategic aims and adequate system for the hungarian agriculture. In the past three decades the clusters has become the most common tool in economic development worldwide. Clusters always base on some local knowledge, and a country can be competitive on the industry in which the resources are concentrated. So the question is, is it possible to „clusterize” the
agriculture and through this develop the rural economic.
Most of the enterprises operating in Hungary belong to the group of small and medium enterprises (SMEs) which means that their total number of staff is less than 250. The aim of the study is to examine SMEs operating within the North Great Plain region. It provides a short summary of the general characteristics of the region, the situation and...significance of SMEs based on the data 2009 and it also clarifies the relevant definitions. The data shows that the enterprise type that is most characteristic in the the region is joint venture (the most popular type is Ltd). It can be laid down as a fact that the number of micro and sole entrepreneurs is also significant in the area. It is also clear that the majority of small enterprises deals
with commerce, while most of the medium enterprises are involved in industry (processing industry). As a continuation of the examination, size of investments, influx of foreign capital, ratio of employed people and grant opportunities are also to be evaluated since these factors influence the operation of enterprises as well.
Due to the exhaustion of the fossile fuel reserves of the Earth, the increase of fossile fuel prices and the difficulties concerning stable fuel supply, the increase of electricity production from renewable energy sources has a special strategic importance. In this study, I am going to evaluate the circumstances of the production and use of ren...ewable energy sources in Hungary and in the European Union. I present the Hungarian economic, energy policy-related and social circumstances which make it necessary to support renewable energy production. I am going to give an overview on the related EU strategies concerning the sector and the Hungarian development plan in this field. I pay particular attention to the examination of development opportunities and the R&D activities going on in this area in Hungary, as well as the efficiency of the means used to improve renewable energy use.
After hundreds of years of drought in the area of Hortobágy and its surroundings brought up the idea of building a channel in Tiszántúl. It started with the idea of an irrigation canal but it ended up in a canal with high importance which can be used in many ways. Because of financial problems the necessary renovations cannot be achieved, an...d as a side effect the amount of silt in the water started to increase, water exploitation started to decrease, and the construction works started to get spoiled. Guided by the Water Directive the East Main Channel has become one of the most significant surface water base in Hungary. To use its water as drinking water brings up a few questions, like solving the pollution problems which problems have already occured. If we want the East Main Channel to be a solution for a long time, further steps and researches are needed to solve the problem of diverting the huge amount of precipitation of the last few years and miantaining the quality of drinking water.
The decrease in Earth's drinking water resources and the degradation of its quality has become a critical problem. Our planet's total water supply is estimated to be around 2 billion km3s. This is only 1% of Earth's own weight. Of this small amount only a tiny 3% is fresh water, of which 79% is forzen in glaciers and 1% is present as surface wa...ters.The ratio of water stored in soil is around 20%. This is 0.2% of the total water supply. Our study aims to summarize the layered groundwater aquifer systems and its changes which are the results of anthropogenic effects in both global and hungarian respects and also for the region of Debrecen.In particular with regard to the geological and ecological level where irreversible
processes take place. All this is discussed in the context of cause and effect. Pointing out the dangers of excessive deep groundwater extraction and the contamination caused by toxic substances that are the byproducts of modern life. In addition we discuss the Water Directive of the European Union which gives a policy for community action concerning the goal to achive the status of „in good condition” for our waters till 2015.
It is vital to examine the strategic plans and leadership insights of the university, the faculties, the departments and the institutions in the research of the „third mission” of the universities. Because of the undertaken social-economic role in the region it is indispensable to know the turbulently changing environment (hazards – oppor...tunities), to map the competencies available in the university (strengths – weaknesses) and to recognize the relations between the external and internal environment. It is an important factor to define the strategic directions of the departments, examining them in direction dimension (pro-active – adaptive) and in role dimension (top-down – bottom-up). The main objective of this research is to recognize the formal and informal strategic visions of the institutes and departments in the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen, and to examine how these visions are related to the university's role in the regional innovation system.
From the precision agriculture point of view, by the rapid development of the investigated technological elements – global positioning system (GPS), remote sensing (RS), global information system (GIS) – the number of services, which were not available in the past, because of their speed, complexity or price are increasing. The high accurac...y high-tech instruments provide opportunity to elaborate several fruit production technologies, which aim is creating and operating water and energy safe quality fruit production systems. To evaluate these possibilities, experience was carried out in the Study and Regional Research Farm of the University of Debrecen near Pallag with the use of a GreenSeeker 505 Hand Held™ Optical Sensor Unit, and its interface the Trimble AgGPS FmX Integrated Display board computer, and a ScanStation C10 laser scanner by Leica. The results show the absolute applicability of these equipments in precision horticulture.
The effect of production factors on maize yield was examined in the Látókép Experiment Site of the Centre of Agricultural and Applied Economic Sciences of the University of Debrecen on calcareous chernozem soil between 2001 and 2003. The impact of environmental factors (precipitation, temperature, number of sunny hours), cultivation methods...(autumn ploughing, spring shallow cultivation) and fertilisation (non-fertilised, 120 kg N + 90 kg P2O5 + 106 kg K2O, and 240 kg N + 180 kg P2O5 + 212 kg K2O) on maize yield was examined. During the three years, autumin ploughing significantly increased yield by 2.91 t ha-1 in comparison with spring shallow cultivation. The yield increasing effect of fertilisation was observed in each year, although its extent depended on the given crop year and the applied cultivation method. The higher fertiliser dose (240 kg N ha-1) did not cause significantly higher yield in either year. After the evaluation of the observed correlations, it can be established that the yield increasing
effect of fertilisation was higher in the case of autumn ploughing in comparison with spring shallow cultivation. The environmental factors (especially the extent of precipitation) significantly affected the maize yield.
Hungary can be divided into 7 regions, of which I am writing about the Northern Great Plain Region in this article. The Northern Great Plain consists of the counties Hajdú-Bihar, Jász-Nagykun-Szolnok, and Szabolcs-Szatmár-Bereg. There are 389 settlements in the region, which can be considered rather few. The population of the region is nearl...y 1.5 million, which is nearly 15% of the total population. This region is one of the most disadvantageous regions in Hungary, with its economic indicators ranking the lowest of all regions. Nevertheless, as regarding education and agriculture, the region is considered to be a prominent area.
In our country, wormwood ragweed (Ambrosia artemisiifolia) may cause serious problems. Nearly 5 million hectares of agricultural area was infected with ragweed (Ambrosia artemisiifolia), which is believed useless weed. Allergological point of view, most problematic weeds adventive. However, many physiologically very beneficial compound also inc...luded, those with the effects have been known also by the Indians. On this basis, herbs can be thought of as ragweed. Our goal was to present that the ragweed contains antifungal active substances as well. In this paper we tested the biological activity of the extracts against Alternaria alternata F.00750 in vitro. We related based on our examination that ragweed contains biologically active agents, by which it is hampered the reproduction of the Alternaria alternata. The minimum effective concentration was 300 mg extract in a Petri dish, which was three days inhibited the growth of fungus. Full fungicidal effect was observed over dose 525 mg.
Nowadays in Hungary nearly 5 million hectares of agricultural area was infected with ragweed (Ambrosia artemisiifolia). According to the public opinion the ragweed is a weed. From agricultural and public health point of view it is exceptionally dangerous plant. As it contains a number of useful active ingredients, based on this the ragwee...d is consider a medicinal plant. Our goal was to present that the ragweed contains antifungal active substances as well. In the experiments we used the pre-flowering plants with roots and we extracted the biological active components of dried plant. We tested the biological activity of the extracts against Monilinia laxa in vitro. We related based on our examination that ragweed contains biologically active agents, by which it is hampered the reproduction of the Monilinia laxa.
Around the Millennium we experienced the worldwide development and the growing importance of the role of higher education played in the social and economic development. A few years later, however, a crisis appeared in the situation of higher education (Kadocsa, 2002). The Hungarian higher education system faces the perspective of serious change...s in its fundamental principals – such as its main activities and the economical ways which are used to finance these activities – even if only parts of the new educational scheme come into effect. Considering this fundamental activity aspect of the issue, there are new challenges which make necessary to rethink the role and aim of higher education and to define the new tasks needed in connection with education, research and other services. Hungarian Education needs to be renewed and improved to avoid a complete
break away; therefore, future priorities and tasks in order to fulfill these priorities need to be defined (Vincze and Harsányi, 2011). The new conception seems to be based on restrictions of the budget as it is experienced recently: a new structure available for a smaller part of society with a restricted budget has been under development. However, not even a battle, let alone a war can be won without money, horses and arms. The recent financial restrictions as well as the parts of the Széll Kálmán plan concerning education prove that serious amounts of governmental funds is taken away from education. The international improvement tendencies contradict to basically all of these Hungarian priorities.
All in all, no reform or change – no matter how much wanted – can be achieved without appropriate funds.
The social care has been accompanying phenomenon of mankind from ancient times. An individual's social and economic processes that affect the lives basically forced the representatives of the powers to help those in need. The concepts used in social care today (equality, solidarity, etc.) have evolved over the centuries, shaped by political ide...ologies of the content. This wide range of people living in today's society for granted the fact that life is present in the social care system, which is necessary for security.
The improvement of Debrecen International Airport has been taking place for more than a decade. The goal is to revitalise the domestic and international aviation of regional centres and connect the Debrecen centred economy zone with other industrial and commercial regions. Considering the market segments of the air cargo industry, and sizing up... the requirements of the enterprises, we are seeking to answer for what possibilities an air cargo operation has, and scheduled cargo flights, what alternatives the location of a cargo base has. Getting to know the technical background of ground handling, communication, safety, and security, we can state that the airport is able to handle international cargo aircrafts as well. Regarding to the quantity of frights, we find that there is a possibility of two flights per week. There is minor need of handling dangerous or unique parcels. The surrounding area of working zone is an excellent territory for locating and building cargo facilities, and its technical background. In case of continuously increasing traffic it is suggestible to use the territory behind the apron as a first step of the development. As the activity extends the second step could be the improvement of the southern zone just beside the runway. This way primarily the
scheduled air cargo flights could appear, then as the traffic of commercial scheduled flights increases simultaneously could grow the amount of
small parcel transportation.
