Abstract: This present paper is based on the importance of the keynesian doctrine in time and tries to make a brief foray into the life and work of John Maynard Keynes, revealing important aspects related to the new concepts this doctrine brought in the history of economic thought, looking at the same time to the criticism addressed to the keynesism and studying the effects they had in the development study of economic science.
The objective of this theory is “the analysis of the mechanism of the market economy in order to ensure sustainable development, reducing or eliminating the disequilibrium, when it is not verified in practice the idea of the self equilibrium through the price mechanism." Keynes wrote in an era marked by mass unemployment, by degradation and suffering at an incredible level. A reasonable person could have supported the failure of capitalism, concluding that only major institutional changes - perhaps nationalization of means of production - could restore economic health.
 
Key words: the Keynes’s, markets economies, unemployment, stability, macro-economy.

Abstract: Agritourism can be considered an attractive and at the same time important land both locally and regionally, which exploits the surplus of household accommodation. It can be prepared and arranged especially for guests, and it assumes the existence of a set of goods and services offered by the farm for the consumption of the people / tourists.
It is also of particular importance, changing in a positive way the life of the locals, increasing the living standards resulting from the use of specific own resources, transforming the structure of agricultural crops to meet the need of tourists. Agrotourism is employment solutions that prevent "rural depopulation," revitalizing crafts and harnessing agricultural products, spreading income sources, facilitating the expansion of investment for tourism, combating environmental pollution by removing sources and preserving conditions living in rural areas, and last but not least the development of sectors: agriculture, forestry, zootechnics and agro-tourism. In order to analyze the services and activities, the agrotourism evaluation indicators, which are expressed by the number of agrotourism hostels, the number of tourists, the number of jobs, the value added of the constructions obtained through the arrangements, the amount of the complementary incomes.
 
Key words: agrotourism, evaluation indicators, complementary revenues
 

THE CONTRIBUTION OF AGRO-TOURISM THROUGH SUSTAINABLE DEVELOPMENT, THE STRENGTHENING  OF AGRICULTURE AND ENVIRONMENTAL PROTECTION

Abstract: Designed as a necessary association between people and nature, as a new way of development that can support the human progress in time, sustainable development can be seen as a harmonization of interests between present and future generations.
Therefore, in order to respond to present needs without compromising the capacity of future generations to meet their own needs, sustainable development planning must be understood as a process unfolding at three different levels: economical - by increasing the exploration and the exploitation of resources, environmental - by avoiding environmental degradation, and social - through jobs growth, traditional crafts, agro-tourism and by strengthening the cultural identity of local communities.
These levels are closely linked with the different problems agriculture and environmental are facing; so, in order to have a proper development/performance, a sound management and suitable solutions, we need a national legislative framework that is harmonized with international rules; this condition must be regarded as the first/prerequisite step to be taken for a sustainable development in the future.

Abstract: The content of microelements in sea buckthorn fruits, leaves and copses was determined through neutron activation. Also, the content from fruits and leaves was analyzed by atomic absorption, for 11 sea buckthorn bio-types. The content in the dry matter was analyzed from the ashes of the sea buckthorn, depending on the harvesting time. The variation in serotonin content was analyzed depending on the origin of the fruits (three geographic regions).
Estimations were made regarding:
-                some ways of processing different plant organs;
-                the biological effects of sea buckthorn;
-                the perspective for serotonin as an imunoinductor in different diseases.
The effects of sea buckthorn are the result of a large number of active physiologic substances, like hydro- and lyposoluble vitamins, hormones and phytohormones, amino-acids (including the essentials), provitamins A, carotenoides, serotonin, melatonin.
The majority of our research done together with research centers: industrials, medical and production units. Serotonin’s effects are well known: immune-inductor, energizing, anti-depressive, chemical mediator, with implications in disabilities like insufficiency in transmitting the information through the nervous system to the organs.
The serotonin with the other substances from sea buckthorn is recommended for sickness or discomfort, too. Mostly concerning the severe conditions that affect the XXI century: cancer, HIV, depression, anxiety, suicide tendencies, insomnia, alcohol abuse, schizophrenia, any disease generate by a phisical, chemical or biological agent.

Abstract: The plants, St. John's Wort, (Hypericum perforatum), Stinging nettle (Urtica dioica), Passiflora (Passiflora incarnata) aerial parts, Sea buchthorn (Hyppophae rhamnoides) fruits, and leaves, Valerian (Valeriana officinalis) roots, grown in own organic cultures, were transformed using standardized proceedings, in order to obtain powders of plants, intermediates in antistress supplement obtaining. The powders of plants were obeyed to physico-chemical analysis for their total content of carotene derivatines (in β-carotene), polyphenols (in chorogenic acid) and flavons derivatives (in rutin), by UV-VIS spectrometry using a double rayed JASCO-UV-VIS V 530 spectrophofotometer. The theory of the degenerative processes, issued as a result of the surplus of free radicals, associated with „oxidative stress”, emphasized the importance of antioxidant activity for the studied plant powders.

Abstract: Currently, in Romania, different energy plants can be grown for production of biomass in mince form (pellet) and wood for construction (for the production of OSB plates). For this purpose, can be cultivated: willow (Salix alba), artichoke (Cynara cardunculus), elephant grass (Miscanthus), Chinese reed (Giganteus), hybrid energy poplar, canary grass (Phalaris canariensis), giant reed, oil tree (Jatropha, the processing, gives an oil used to produce biodiesel). Valorification of the willow eco-bark consists in obtaining dietary feed supplements like: dried extracts, aqueous extracts, glicero-hydro-alcoholic mixtures or compressed with effects on health which can be demonstrated by case studies and clinical studies.
 
Key words: eco-energy plant, willow.
