RISK ANALYSIS AND ADOPTION OF DECISIONS BY USING PALISADE SOFTWARE PACKAGE

Vasile CRISTIAN

Abstract: The rising volume of information conveyed and the speed of work are becoming increasingly necessary applications and devices to meet these requirements. Thus, in the actual society of knowledge, the impact of the new informational technologies was extended even in an important domain of human activity: the adoption of decisions. Consequently, the necessity of objecting at the selection process of the most favorable decision lead to the extension of the usage of information technology also in the conceptual phase. The decision tools suite (DTS) and the expert systems have the answer for the computer science workers at the needs of the deciders, used especially in the case of the decisions adopted in conditions of risk or uncertainty. The PALISADE package of programmers is a support system of decisions, which overlaps the processor tables, increasing the possibility of usage, especially for simulation problems, calculating the risk, building decision trees etc.

INTERNET INFORMATIONAL SYSTEMS IN AGROTOURISTICAL EXPLOITATIONS’ DEVELOPMENT

Alin Daniel MUNTEANU

Abstract: Telecommunications companies, entrepreneurs, and policymakers have regarded rural and poor markets with some combination of too-complex-to-serve and not-interesting enough (politically or economically) to be worthy of sustained attention. But times – and technologies – have changed, leaving what have been perceived as backwaters poised to become significant growth areas in the next decades.

Abstract. The deuterium depleted water has a special influence on cells and tissues development. A decreasing of the deuterium concentration in tissues or bodies, significant slow down the proliferation of a lot of types of cancer. The aim of this work was to determine the antioxidant effect of deuterium depleted water (DDW) on rats with chromium induced oxidative damages (20 ppm Cr/ b.w. single dose as K2Cr2O7). Deuterium, malondialdehyde (MDA) and glutathione (GSH) blood levels were determined. After Cr(VI) intoxication, increased MDA and low GSH levels were registered. DDW administration could maintain both small deuterium and normal MDA and GSH levels. Low levels of deuterium in cells are favorable for good cell function. DDW performed an important Cr (VI) scavenger role in the rats`liver.

Key words: deuterium depleted water, malondialdehyde, glutathione, chromium, blood, rats

NEW SURFACE FOR THE PREVENTION OF BIOFILMS AND BIOFOULING – A REVIEW

Fei YANG, Uta CHERUTI, Robert ARMON

Abstract. Since the early 80–s of the last century, biofilm study took off as a discipline on its own. The importance of biofilms in everyday life is beyond any doubt and beside its biotechnological advantages in large processes the hazardous effects are broad with serious financial effects in industry, health and environment. The main process of biofilm formation is its biofouling of almost all surfaces known to human kind (natural and synthetic). To prevent biofouling, new approaches were studied to inhibit surface colonization through development of new hybrid materials, use of biocides and antibiotics, understanding cell–cell communication (quorum sensing) as well physical measures. Hand to hand with advancement in materials chemistry, these new surfaces were developed with variable achievements due to the large diversity of biological systems. The present review describes some major directions in biofouling prevention through surface modifications.

PRODUCTIVITY OF ALFALFA GERM PLASMS. NEW DATA ABOUT ALFALFA ROOT LONGHORN BEETLE (Plagionotus floralis Pall.)

Evgeniya D. ZHEKOVA, Dimitriya S. PETKOVA

Abstract. During the first ten years of the new century a strong attack on alfalfa (Medicago sativa L.) was observed by the considered as economically insignificant alfalfa root longhorn beetle (Plagionotus floralis Pall.). The investigation was carried out in competitive variety experiment with 8 entries–7 new germplasms and the standard Prista 2 variety. The productivity of the alfalfa germplasms was determined during the period 2006–2009, including dry matter yield and yield of seeds. Number of green branches per plant; thickness of the root neck (mm), air–dry weight of the green mass (g) and number of moves and larvae of alfalfa root longhorn beetle were registered. There is a close correlation between dry matter yield, number of plants, diameter of root neck and number of moves and larvae of alfalfa root longhorn beetle. Number of larvae and moves of the pest could be more than one in one and the same root.

EXAMINING THE FACTORS OF QUALITY OF LIFE – A CASE STUDY IN BUDAPEST

Éva IZSÁK, Ferenc PROBÁLD, Annamária UZZOLI

Abstract. After a brief introduction describing the urban environment of Budapest, the local differences in the quality of life are characterized by means of an index derived from the broadest set of variables that are available for the 23 districts of the Hungarian capital. The concept of HDI is also adapted to the urban districts and by regressing its value against property prices, an extremely strong correlation could be revealed. Out of the components of HDI, the education level of the resident population appears to be most closely connected with the property values. By disaggregating the real estate transactions database of the years 2005 and 2006 according to street addresses in the hilly Buda districts, it is possible to assess the impact of altitude on the residential property values. The mean price related to unit floor area of the apartments reaches a peak at a height of 200 meter above sea level where favourable environmental attributes, like proximity to open space and visual amenities are coupled with prestigeous image and high status of the population. Beyond the natural endowment, the scarcity of land available for housing in the Buda Hills and high construction costs due to the physiography are also capitalised in the property values. Conclusions bearing relevance to urban planning are summarized in a SWOT analysis at the end of the paper.

Keywords: Budapest – HDI – Urban environment – Quality of life – Property prices – SWOT analysis
