Regional innovation: State of the art in the Észak-alföld region
139-143Views:84Innovation and innovation performance is gaining increasing importance in European policy, as the targets determined by the Lisbon priorities related to innovation seem to be still far away from the reality in some European countries and at EU level as well. Although the economic crisis determined the priorities of economic development and made it more complicated to dedicate more budget of Research and Development, one of the five ambitious objectives of the EU’s growth strategy for the coming decade: Europe 2020: A strategy for smart, sustainable and inclusive growth is still focusing on innovation. As the Lisbon Strategy determined the paths for national targets in the given areas, Europe 2020 will be adopted as well by the Member States.
In this context, the current work would like to give a short overview how Lisbon Strategy effected the national and regional innovation system in Hungary and will analyze its impact on Észak-Alföld’s region Research, Development and Innovation performance in the recent years and the transition of regional innovation governance system. -
Study of animal welfare status in dairy cow herds in Hungary – looking for causes of lameness
47-50Views:175In the last 20–30 years lameness in cattle was found to be third the most influential disease next to mastitis and reproduction disorders. Studies have been established to explore reasons for lameness and prevention. The problem with more robust prevention plans is that knowledge and research evidence is not strong enough to run an effective prevention plan. The aim of the research is to look for reasons of lameness by observing number of cows on 6 farms during 2 lactations. Performance data will be put together to body condition score (BCS) and lameness scores. Other examination is focused on monitoring of 40 farms. This part of the project is more related to extension, collecting and sharing solutions for decreasing lameness. Producers are advised what kind of measures are possible to reduce occurrence of lameness. Effectiveness of those actions will be measured at the end of the study. The first preliminary results show lack in almost all preventive measures needed to be taken in minimising lameness. Those areas are related to poor facilities, lack of straw, problems with labour and basic management.

Vegetable production based on waste heat in closed greenhouses considering economic usage and competitiveness of the European Union
41-44Views:117The study investigates two professional fields; the questions of vegetable production in greenhouses, the necessary steam supply and heat regulations. The actuality of this investigation is provided by the planning of a combined cycle power plant of 2400 MW in Hungary. According to the plans the steam developing by generating electricity in the power plant can be used to intensify the vegetable production. In my current study I present the experiences and results gathered as member of the research and development team led by Mr. Dr. Sinórós-Szabó.

Comparison study of student with special educational need in elementary school
71-76Views:148The aim of this lecture is to observe the status of students with special educational needs (SEN) in Europe and Hungary. The European Union has made tough decisions in financing and educating disabled people, so they can be integrated into the society. According to the European directives, Hungarian jurisdiction and educational politics tend to follow the pedagogical processes. The relevant juridical and economical laws for SEN students have already been implemented. The number of students with SEN in Europe increases permanently, so it is reasonable to detect their controversy. Despite this fact, differences can be experienced in teaching methods among primary schools, as a result development of SEN students can be different. The aim of this study to compare the motor skills of SEN students in two different primary schools, with different pedagogical program. My research base were the Ferenc Móra primay school and Gyermekház alapítvány primary school in Budapest. My main question was, if a specially developed program targeted SEN students can increase their motor skills. Studying the girls in the 2 age-groups, we have not experienced significant differencies out of the 3 motor tests between the control and the experimental groups.
Studying the boys in the 2 age-groups, we have experienced 3 significant differencies out of the 3 motor tests between the control and the experimental groups. SEN students, who have been taught in segregated form with the help of ’Alapozó Terápia’ – a special therapy – achieved better motor skills. The study makes recommendation to primary shools how to organise trainigs for these students. -
Recent data about the fish consumption of great Cormorant in the area of Hortobágy Fish Farm Co
75-80Views:217The cormorant (Phalacrocorax carbo) is a bird species that nests sporadically but in colonies, besides larger fishponds and rivers in Hungary. The number of its individuals has been increasing during the last two decades. The species eats solely fish, therefore it can cause serious depredation of the fish stocks in fishponds of intensive system and after the freezing of the ponds, in larger rivers, which are not yet frozen. The aim of our research was to reveal the damages the birds can cause on the studied areas and the extent of the losses the Hortobágy Fish Farm Co. has to realize.
Our studies were carried out between April 2012 and November 2014. During cleaning, the investigation of the craw contents of the birds and their biometric studies were conducted. The results revealed the diverse food base of the species. In the samples, we have determined 379 fish individuals; in 368 cases, the exact fish species were determined, too. Significant differences were found between the consumed fish species rations of the units (P=0.05% beside). We have also found significant difference in the fish consumptions of adult males and females.
Under the ever harder fish production conditions, the presence and thus the permanent predation of the birds affect the fishermen. In favour of maintaining ecological balance as well as to hold the income of the fish farmers, elaboration of adequate protective and preventive methods will be needed in near future.

Evaluation of the blood product characteristics of meat meal and hemoglobin with non-invasive methods in the VISNIR wavelength
49-56Views:243The separate collection of poultry slaughterhouse trimmings and blood is partially solved in Hungary. Only properly prepared animal by-products, protein meals can be utilized as animal feed additive. However, different protein meals are appropriate for feeding different animal species. That is the reason why it is important to avoid accidental cross contamination of the products. Meat and blood meal produced on the same technological line, therefore mixing of the products can happen in various proportions during the shift of production.
Thus the aim of this study is to develop a spectral method which will allow to estimate the ratio of meat and blood protein meal in the final product. During the test the products were mixed in different proportions and were examined by the spectral method. Measurements were conducted with AvaSpec 2048 spectrometer in visible (VIS) and in near infrared (NIR) wavelength range (400–1000 nm) to define the spectral differentiation of the different meal products. Significant difference can be detected in spectral reflectance between the meat and blood product in the VIS-NIR range. The blood product has a characteristic spectral property: in the range of 600 and 735 nm reflectance values are increasing following a sigmoid curve. This property is not observed in the case of meat meal: close to linear rising is detected. Effective protein rate and purity detection could be made by Blood Product Sensitive Mixing Index (BPSMI – R930/R600), and by the calculation of inflection point in 600–735 nm.

Stability and development of Transdanubian agricultural enterprises
77-82Views:115Personal fulfilment, financial security, flexibility, relationships, information, rules - these are all hallmarks of entrepreneurship. Furthermore, one more important factor should be added to the list, which enables satisfaction resulting from reliable income and self-fulfillment: this is openness. An open mind to changes, to novelties, and to the workforce is necessary. The central question of the present research is how to effectively develop Hungarian small and medium-sized agricultural enterprises, especially in the Transdanubian region, by utilizing these factors. In addition to production, institutional and price risks, agricultural enterprises, like other sectors, are also affected by massive labour shortages and resource-intensive development objectives. In the research, primary agricultural producers, micro, small and medium-sized enterprises were surveyed through questionnaire in the second and third quarters of 2019. Using the snowball method, both the development opportunities and the risks were mapped in this sector, mostly among growers. The research results show that there is a correlation between satisfaction and development and favorable workplace relationships. These correlations were presented by demonstrating the relationship between technological development, income satisfaction, stable job creation, and the need to try new developments. However, there seems to be an invisible boundary to development in the examined field, which may stem from uncertainty, and yet, it is important to maintain development and learning activity so that the right knowledge and know-how is available to the business when needed. Since the results show that there is a lack of openness to new technologies among the farmers in the studied region, and this may pose a problem in the future in terms of meeting the expectations of precision farming, it is recommended to focus on innovation in the agricultural sector in Hungary.

Investigation of combining ability and superiority percentages for yield and some related traits in yellow maize using line × tester analysis
5-14Views:242Combining ability estimation is an important genetic attribute for maize breeders in anticipating improvement in productivity via hybridization and selection. This research was carried out to investigate the genetic structure of the 27 F1 maize hybrids established from nine lines derived from Maize Research Department and three testers, to determine general combining ability (GCA), determine crosses showing specific combining ability (SCA) and superiority percentages for crosses. Nine lines, three testers, 27 F1 hybrids and two check commercial hybrids (SC162 and SC168) were studied in randomized complete block Design (RCBD) with three replications during 2016. The results of mean squares showed that significant and highly significant for most studied traits (days to 50% tasseling, days to 50% silking, plant and ear height, ear position, ear length, no. of kernels per row, 100-kernel weight and Grain yield). Estimates of variance due to GCA and SCA and their ratio revealed predominantly non-additive gene effects for all studied traits. Lines with the best GCA effects were: P2 (line 11) and P6 (line 21) for grain yield, for testers Gm174 and Gm1021 had significant GCA effects for grain yield. The hybrids P5×Gm1021, P6×Gm1021, P7×Gm1021, P8×Gm1002, P9×Gm1002 had significant and negative SCA effects for grain yield. Crosses P1×Gm174, P2×Gm1002, P5×Gm1021, P6×Gm174, P6×Gm1021, P7×Gm1021, P8×Gm1002, P9×Gm1021 were the best combinations manifested and significant superiority percentages over than check varieties (SC162 and SC168) for most studied traits. Therefore, these hybrids may be preferred for hybrid crop development.

Description of the Micro-Loan Program, payment and conclusions
81-86Views:71The system of microcapital goes back 8 years in Hungary. Its strategy and practice developed at a time when really small enterprises emerged with little practise and even less capital. Specialists organising and executing programs started with microcapital with little experience. This programme provided the young and experienced an opportunity to gain experience they lacked, and seems to have been extremely successful.

Ecological Factors in Settlement Marketing Projection for Balmazujvaros
9-14Views:89Marketing is a crucial tool for regional and local governments, and should be better employed before Hungary joins the European Union.
In my article I refer to the five-step process of environmental and situational analyses indispensable for a strategic plan, which serves as the basis for a marketing concept for a settlement. Furthermore, I present the necessity of the macro, mezo and local levels of environmental analyses. This part of my article is aimed at clarifying the notion of ecological marketing. My objective is to discuss its relation to settlement marketing.
The second part of my article investigated the emergence of ecological factors in settlement marketing, in its process, using the example of Balmazújváros. I presented the correlation between Balmazújváros and Hortobágy National Park, from which I investigated primarily important areas focusing on the protection and development of natural values.
In the course of strategic planning and the everyday operation of the town, ecological aspects have to be highlighted, and this process needs the development of the appropriate system of institutions and relationships. Now we can only see certain elements of environmental protection in the strategic settlement planning of Balmazújváros, and we seek to further enhance this process in the future. -
Bioreactors in Hungary
248-254Views:113The transformation and utilization of organic materials must occur with the highest degree of environmental conformity. This conformity – in accordance with the guiding principles of the European Union – will result in a new economic and systematical approach. We can establish the profitability of projects with the utilization of surplus effects which characterize multiple-product lines.

The strengthen of the second pillar in the European Union and Hungary
88-94Views:84The Common Agriculture Policy (CAP) took shape in the early 1960s. At that time the first action was to stop food shortages. Among the objectives of the Treaties of Rome appeared the subvention of rural development had not yet.
Rural development appeared, in 1992, in connection with accompanying measures, and by end of decade, the European Agricultural Model had taken shape. Agenda 2000 pointed out the direction of rural development and introduced the first and second pillars in the CAP. The regulations of rural development were simplified by 1257/1999/EC, which stressed the importance of rural development to and it has to continue the principle of subsidiarity and has to be decentralized.
The last enlargement raised new problems, the mid-term review of Agenda 2000 occurred and resulted in a new CAP-reform in 2003. The 1783/2003/EC rural development regulation modified the previous regulation. According to the new regulation it is necessary to strengthen the new rural development policy, enlarge the circles of accompanying measures, place greater emphasis on requirements of environment, human resource, animal welfare and plant health. Digression and modulation take part in the new CAP-reform in order to increase the role of rural development in the common budget.
In the next budget from 2007-2013, the European Union wants to create a single rural development fund and simplify programming, financing, monitoring. The EU wants to enlarge the instruments of rural development with a four axis model. -
The launch on the way to development or the „revival”... (Comparisons of theoretical and practical approaches apropos of the change and crisis management process of smes and mature companies) .
65-70Views:70Hungarian SMEs, just like those in other EU member states, often cease for various reasons. Among these factors are many, which should not necessarily turn out this way. These factors are studied in numerous countries while the attempt is also made to create the systems of conditions for these enterprises to recover – often through various aids and supports (from public supports to non-governmental initiatives). Among other things they are trying
to organize those services with the help of which – if there is the slightest hope for survival – those SMEs in trouble or having serious difficulties could avoid going down by recovering from
their problematic situation and getting improvements.
These days this issue comes up more and more urgently in Hungary, as well. It has quite a few signs indicating that – among other things – the reports, the enquiries and commissions of the
National Association of Change and Crisis Managers (VOE), all of which – just like "thermometers" – reflect this tendency well.
I have been doing research on this topic since 1993. As an expert I utilize them, and as a VOE member, vice president, then president I process the relevant Hungarian but mainly French
experience on the subject. I intend to present those few theoretical and practical results and applicable experience I have reached this way in this presentation of mine. -
A forgotten sour cherry pest, the stone fruit weevil (Anthonomus /Furcipes/ rectirostis L.) appeared again
104-106Views:76The stone fruit weewil (Anthonomus rectirostris L.) has been known as the kernel pest of the wild cherry in Hungary. There have been no data about its harm on sour cherry (Prunus cerasus L.) in our country, yet. 5-10% of stone infection has been observed on some sour cherry trees (cultivars: Debreceni bőtermő, Újfehértói fürtös) in the eastern side of an orchard at Debrecen-Józsa adjacent to a wood in early July 2011. The damage can be in connection with the fact that the yield has not been harvested for years.

Energy crops on less favoured (alkaline) soil
115-118Views:103The reduction in fossil energy and row material sources induces growing demand for renewable resources. The growing demand for herbal raw materials has land use impacts as well. One way to reduce the conflict between the food and energy crops can be the utilization of less favored areas by growing energy crops. Among the potentially available areas for this purpose the salt affected soils (SAS) occupy a significant territories. SAS with structural B-horizon (meadow solonetz soils) represent the most wide spread group of SAS in Hungary. About half of these soils have been reclaimed and used as arable land and the remaining 50% are used as grassland. Sweet sorghum production for manufacturing of alcohol production was investigated in a long term amelioration and fertilization experiment on a salt affected soil (meadow solonetz). By means of regression analyzes the effect of sodium content of the soil and increasing mineral fertilizer doses were studied. According to the multiple regression analysis only the effect of nitrogen fertilizer was significant. On the solonetz type salt affected soil the effect of water soluble salt content of the soil was not significant, but there was a closer correlation between the ammonium-lactate sodium content and the yield of sweet sorghum. The maximum green mass was 45–50 t ha-1, in the case of low Na content and high level of nitrogen fertilization.
In order to quantify the potential yield of natural grass vegetation the relationship between the soil forming processes and the grass vegetation
was investigated. Beyond the different forms of Na-accumulation, the spatial pattern (mosaic-like characteristic) is also an inseparable feature of salt affected soils. The difference in the water regime, caused by the micro-relief is the main cause of variability. The run-on water keeps the deeper parts of the catena position wet longer. The wet situation causes more intensive leaching. In the low-laying parts of salt affected soils species preferring wet situations (mainly Alopecurus pratensis) are in majority. On the higher parts of the micro-relief species tolerating dry situations (mainly Festuca pseudovina) are dominant. The yearly grass production of low laying areas can be 4–7 t ha-1 but because of prolonged wet conditions the grass is not grazed and mowing can only be in old state. This old grass is not proper for feeding, but it may be suitable as energy plant. -
Optimizing fish structure in angling ponds focusing on white fish
33-36Views:168According to new amendments of laws, commercial fishing licenses of natural waters shall not be issued from the calendar year 2016 in Hungary. However, the most settlement of white fish to angler ponds originated from natural waters. Currently, there is no sufficient quantity of fish species belonging to this group available to fulfil the settlement commitments of fish farmers. The aim of this recent study is to develop a breeding and production technology that is suitable for settlement of large quantities of this fish species of appropriate length of (4–5 cm). The following methods are investigated: aquaculture cage system (pond-in-pond system), monoculture and mixed population with different ratio of white fish in fish structure. Due to the different environmental needs of different fish species, many parameters need to be investigated, for example: stocking density, feeding, oxygen level, monoculture or mixed populations, growth potential and mortality. A preliminary experiment was carried out following the artificial propagation of ide (Leuciscus idus) following a 21-day larval rearing experiment in which the effect of different stoking density was investigated for mortality and growth. On the basis of the expected results, the optimal conditions for the aquaculture cage system will be described, regarding to the white fish stock.

Comparative analysis of Carpathian Braunvieh’s morphological traits
15-19Views:189The Carpathian Braunvieh cattle established by the cross-breeding of the Schweizer Braunvieh and the local breeds of the Carpathian basin approximately 150 years ago. The evolved three usage breed was durable and resistant, however in comparison with the high-productivity breeds was less competitive. The dramatic lay-off, and the endangered status of the breed requires a conservation programme. University of Debrecen took the investigation of the Hungarian population and it’s detailed genetic studies. Within this research project among others we carry out body measurements and rates of the body traits. Depending on these results, we may decide on the subsequent gene-reserving objects. Based on body measurements and live weight we established that the breed at Mikóháza favours to the one lived in Hungary in the 1960’s, and to another, named Ukrainian Carpathian Brown. Compared to the earlier data (Horváth, 1966) smaller body traits can be seen. Our livestock is proportionately smaller than the other breeds in height at withers, as well as in live weight. Based on the comparative analysis, we established, that – thanks to the aware sorting – the imported individuals represent the ancient, primitive Carpathian variant.

Investigations of Thrips tabaci and Aeolothrips intermedius population dynamics in tobacco plantations
121-127Views:191Studies were conducted between 2015 and 2017 with yellow sticky traps in seven tobacco plantations. The purpose was to determine when and in what numbers onion thrips individuals can settle into tobacco plantations. The primary objective of the study was to determine the proper timing of chemical treatments, furthermore, the determination of crucial factors that can influence the population dynamics of Thrips tabaci.

The specification of the growing temperature on PDA of chestnut blight pathogen (Cryphonectria parasitica (Murr.) Barr) to optimize timing for biocontrol treatments by hypovirulent strains
29-32Views:173The most destructive pathogen for the European chestnut trees is the blight fungus Cryphonectria parasitica (Murr.) Barr. The biological control is the only effective possibility to apply in situ biocontrol by hypovirulent strains against compatible virulent (wild) fungus strains. The infested bark tissues can inoculate by drilling holes surrounding and putting into agar discs interwoven by the appropriate vegetative compatible group (VCG) hypovirulent fungus strains. This latest can pass those virus-like particles (VLPs) by parasexual contact (called hypha-anastomosis)which responsible to hypovirulence. A laboratory experiment was made to find the optimal times to carry out the treatments. The intensity of growth of fungal colonies were analysed on different temperatures. The growth of the fungus on low temperature were rather slow,according to our expectations. On higher temperature the colony progress were the same as on the optimal 20–25 °C. These observations and the environment determine the date of the field applications under Hungarian weather conditions. It means the optimal treatment periods can be May or end of September to middle October in Hungary.

The Role and Importance of Variety in Intensive Cherry Production
81-84Views:69Increasing the intensity of plantations is a basic precondition for the renewal of fruit growing in Hungary.
The intensification of production of stone-fruit species is difficult for several reasons. In particular, knowledge of dwarfing rootstock is very limited. In this study, we tried to achieve smaller-sized, intensive crown formation by co-ordinating the date and degree of pruning.
In intensive cherry production, the most important variety-dependent characters determining the formation of the required productive surface are vigour of growth, branching potential and quantity and quality of the buds.
In this paper we have demonstrated that significant differences exist between varieties in these characters. -
The father of the term ‘biotechnology’ was Hungarian: The forgotten works of Károly Ereky
107-110Views:313In the Nature, Robert Bud gave an account of the fact that the generator of the concept "biotechnology" was the Hungarian Karl Ereky who, in his book published in Berlin in 1919 entitled "Biotechnologie der Fleisch-, Fett- und Milcherzeugung im landwirtschaftlichen Grossbetriebe" ("Biotechnology of Meat, Fat and Milk Production in a Large-Scale Agricultural Farm"), disclosed his observations and new views in that regard. Later on, Ereky's two essays, published in German language again, and other contemporary German sources have been processed which have confirmed the assumption whereas – in scientific terms – the further first applications of the expression "biotechnology" can be attributed to Ereky's works. Recently, we have explored and found biographical sources and documents which had been published by Ereky, which, however, have already been forgotten, by dint of which the story of origin of the first concept "biotechnology" can as well be clarified in a factual manner.

Theoretical Basics of Internal Auditing at Public Administration Institutions
154-159Views:69In the past months, in the time of the reforms of the new millennium, the modernisation and transformation of the public sphere have been a constant issue in Hungary due to globalisation and the country’s accession to the European Union. The provision of transparency and comparability is required from each member state by the challenges of globalisation, legal harmonisation and the unification process. That is why it is essential to harmonise and adjust to one another the internal and external auditing systems of public institutions on the levels of both the institutions and sectors. The study reviews the theoretical foundations and basic principles of the public institutions’ internal auditing system, as well as it aims to provide an overall picture of the legal background of the auditing system and its changes. By including the main principles, standards and the most important regulations, the study’s informative approach aims to assist anyone interested in the further and deeper research into the subject.

The effect of keeping technology on the microbiological status of raw milk
67-75Views:114The importance of the quality of raw milk increased after Hungary had joined to the EU. On delivery of raw milk, the microbiological quality, especially total plate count of the milk is very important. Twenty-two farms (7 large, 4 medium-sized, and 11 small farms) were included in the study. We considered the different farm size, keeping- and milking circumstances during the selection of farms. The examined large farms use loose housing system (cubicle, deep litter) and milking parlour. Most of them use preand post-milking disinfection. In the medium-sized farms, loose,
deep litter and tie-stall housing system, as well as milking parlour, pipeline milking and bucket milking occurred. All of them use preand post-milking disinfection. Small farms use tie-stall housing system, bucket milking and udder preparation by water. Unfortunately, they do not use pre- or post-milking disinfection. In the large and medium-sized farms mainly Holstein Friesian, in the small farms Hungarian Simmental breeds can be found.
The aim of our research was to examine the microbiological status of the raw milk produced in dairy farms (total plate count, coliform count, Escherichia coli count, Staphylococcus aureus count, psychrotroph bacteria count, furthermore yeast and mold count); sources of the contamination; connection between the microbiological quality of produced milk and housing-, milking technologies of farms; furthermore the hygienic circumstances of milking and milk handling of the farms, by the examination of coliform bacteria and Escherichia coli contamination.
During the examination of the connection between the different farm sizes, various housing- and milking forms and the microbiological characteristics we observed similar tendencies in the case of total plate count, coliform count, yeast and molds count, furthermore psychrotroph bacteria count. The value of these parameters was significantly higher in small farms, and infarms which use tie-stall housing forms, bucket milking, udder preparation with water, and which do not use pre- and post-milking disinfection.
The results showed that besides cooling, the milking procedure and the type of udder preparation had the largest effect on the total plate count. Statistical analysis shows that in medium and small farms the combination of pipeline milking – tie stall housing system – disinfectant preparation of the udder; in large farms the combination of milking parlour – loose cubicle housing system – dry preparation of the udder are the most appropriate in the aspect of the total plate count. We experienced that in farms where the hygienic instructions are not followed – and therefore
equipment used during the milking and handling of milk is very contaminated – or rather the separation of mastitic cows’ milk is not appropriate, different microorganisms may contaminate the produced milk. -
Consumption tendencies of foods of animal origin in Hungary
7-17Views:129One of the most important indices of the population's food consumption are the quantities of the consumed foods expressed in a natural measure. In the course of my examination from the 1980 years I examined how our dietary habits changed. I was able to demonstrate it by the time series examination well, in which years and in a what kind of measure these consumer changes occurred. The trend analysis was in it onto my help, that let me be allowed to depict his beat as the changes of the food consumption visual.
In his totality the Hungarian population nutritional and from his consumer customs we may relate that the present nourishment increases it unambiguous the diet pendant the risk of illnesses, furthers their development, aggravates their effect, and contributes to the population's adverse health conditions powerful.
It was over in some years, in a decade on a unfortunate manner, we lost the natural instinct of the selection of the food in a considerable part. Our diet fundamental the narrower and the customs of wider environment, his rules, the social values, beliefs define it. Because of this to feed it is necessary to study it.
The changed and the health-conscious nourishment would be important for him herding back into a upturned dietary habit correct bed with a wide circle recognizing him with the population, his role could be big for the healthy, or functional foods. The nourishment gives his pleasure likewise while we take over healthy foods.
The recognition of the changes of the demand and accompanying him with attention could be the domestic food producers' fundamental interests. The consumer types and the market segments should be mapped, that they suitable marketing a strategy can be aimed at it, and into the direction of the healthy nutrition to push away, and would be need onto an efficient informative campaign, onto an advertisement message formulated well, onto the making aware of this, that let the advertisement supply an educational function in one. -
Harmonic development and biodiesel
91-95Views:86An increased expansion of renewable resources and biodiesel is observed and prognosed, since fossile energy resources are about to run out. Hungary achieved outstanding sunflower years in the recent years in worldwide comparison. In the future, the feedstock of biodiesel production can also be rape besides sunflower.
According to the concept of harmonious development, the balance between nature, society, economy and human environments is represented by their mutual presumptive character. Research and development need to be aligned into this system. Our aim was to examine the advantages and
disadvantages of biodiesel production in different environments, using a model to do so. In order to maintain the harmony, the existing resources have to be managed properly, taking the correlations of the system into consideration. Targeted technological developments are necessary, similarly to the improvement of energy safety and efficiency.
