Production and Producer's Behavior in a Competitive Environment

The consumer goes to market in order to buy the products that are useful for him or simply to buy something which makes him happy. In other words he tries to satisfy his basic needs (such as food, clothing etc) as well as the secondary ones. The producer comes to market with the products requested by the consumers and tries to sell it at a price that would cover production costs and obtain a profit. The manufacturer must meet the consumer desires offering him those products that have desirable characteristics, have a nice design, etc. The manufacturer has a multitude of ways to promote his products so that they can be sold and not kept in stock, there by wasting a substantial amount of resources.production, producer, environment, competitive advantage.

PHYSIOLOGICAL PARTICULARITIES OF THE SPECIES VISCUM ALBUM L. ssp.album AND LORANTHUS EUROPAEUS Jack, HEMI-PARASITES ON LIGNUOUS SPECIES FROM THE COMANESTI FOREST, ROMANIA

      In the study which had been carried out in the Comanesti forest from the Mehedinti County, Romania, there have been taken into consideration two hemi-parasitic species frequently found in this area: Viscum album, a parasite found on Acer campestre, and Loranthus eurpaeus, a parasite found on Quercus cerris.    During the summer time, the two hemi-parasitic species which have been takes under study show moderate values for the photosynthesis and transpiration, but increased values in the case of leaf respiration.   The leaf suction force presents high values, these ensuring both the absorption and the conduction of brute sap.   The chlorophyll pigment contents indicate higher values in the case of Loranthus, when compared with the other species, Viscum, in the same lighting conditions.    In Viscum album, the water content shows a seasonal variation, with a maximum during the spring time, after the appearance of leaves on the host plants.          In the case of Loranthus, the maximum water content is recorded in early June

Dimensions of the Romanian Labour Market in the Context of European Integration

The purpose of the article is to identify, through a retrospective analysis, the main trends of the labour market and starting from this point to outline directions of action which aim at matching supply and demand on this specific market in Romania. Finally, the paper presents the perspectives of the labour market in Romania as a new European Union member, outlining the importance of institutional capacities development, of sustainable occupation and development, of continuous formation, as well as the importance of maintaining the biologic potential of the labour resources and minimal standards information.population, occupation, labour resources, labour supply, labour demand

PARASITIC PLANTS AND THEIR PHYSIOLOGICAL INTERACTIONS IN THE NATURAL ECOSYSTEMS

This paper presents the results of a research which had been carried out on the physiology of the parasitic plants Cuscuta campestris Yunker and Orobanche caryophyllacea Smith.     The physiological indices which have been analyzed were: respiration, transpiration, total water content, bound and unbound water, osmotic pressure,  suction force,  the phosphorus and potassium contents.     The recordings show an increased value for the transpiration, a high content of total water, a low percentage of bound water and high values of osmotic pressure and suction force. The data obtained after these studies had been compared with the recordings from the host plants.    The results from the host plants indicate the following: reduced osmotic pressure of the cellular juice, a reduced suction force and a lower overall water content.   The ash content is greater in the case of the parasite plants, compared with their hosts.    At the same time, the phosphorus and potassium contents are clearly superior when compared with the values determined for the host plants

PHYSIOLOGICAL FEATURES OF THE TERRESTRIAL ORCHIDS CEPHALANTHERA LONGIFOLIA AND PLATANTHERA BIFOLIA THAT GROW IN THE PEDO-CLIMATIC CONDITIONS FROM OLTENIA REGION OF ROMANIA

For studying the physiology of terrestrial orchids, plants from the species Cephalanthera longifolia and Platanthera bifolia have been used. The experiences were carried out directly on the field, in Mehedinţi County, Comanesti Hills. In both species of orchids, the seasonal dynamics of photosynthesis registers a peak during the flowering period that corresponds to a maximum content of assimilating pigments and also a maximum leaf surface. In terrestrial orchids, the seasonal dynamics of leaf transpiration intensity is highest during spring, when the water content in the soil is high and minimal in summer. The graphs showing the diurnal variation of photosynthesis for the two species indicate that Cephalanthera longifolia prefers semi-shaded and sunny habitats, while the plants of Platanthera bifolia that are found in the studied areas prefer a more shaded environmen

About some techniques of improving numerical solutions accuracy when applying

Abstract-The present paper is focused on analyzing different sources of errors that appear when using Boundary Element Method (BEM) to solve problems, and illustrating their influence on the numerical solutions accuracy. The study is made considering the errors that appear when BEM is used to solve a problem of compressible fluid flow. Analytical checking is used by referring to cases when the problem can be exactly solved, and so, the numerical solutions are compared with analytical solutions in order to check their accuracy. Some techniques to minimize the errors in order to get better numerical results are presented

Computer-Based Decision Support for Railroad Transportation Systems: an Investment Case Study

In the last decade the development of the economical and social life increased the complexity of transportation systems. In this context, the role of Decision Support Systems (DSS) became more and more important. The paper presents the characteristics, necessity, and usage of DSS in transportation and describes a practical application in the railroad field. To compute the optimal transportation capacity and flow on a certain railroad, specialized decision-support software which is available on the market was used

ECOPHYSIOLOGICAL FEATURES OF SOME CALCIPHILE PLANT SPECIES FROM NATURA 2000 DOMOGLED-CERNA VALLEY SITE

The calcareous substrate found in Natura 2000 Domogled-Cerna Valley site, allowed the installation of vegetation with a strong calciphile character. The most interesting adaptation of these plants is linked to mineral nutrition, some of them having the ability to remove the excess of calcium at the leaf level due to the presence of special glandular formations.Another adaptation is linked to water regime. The small amount of water they have available in their body is preserved due to the low intensity values of transpiration.Photosynthesis registers a diurnal variation with a peak at noon in wetter periods and in the morning during drier periods
