CONSIDERATIONS REGARDING THE INTEGRATED MANAGEMENT OF FRESHWATER LAKES IN TRANSYLVANIA PLAIN
Ioan FODOREAN
Lakes reservoirs and ponds , 2008,
Abstract: Lakes appear under more forms and dimensions and include lots of features that constitute important advantages in defining them as a class of objects that need to be studied. They have very well defined limits and there are open systems that receive water, solar energy and chemical substances from outside the system. The foreign specialty literature provides special attention to the study of the lakes and the swampy fields of their neighbourhood, as well as to the numerous interactions that come out from the existence of these water units. In this purpose, proper paradigms of the study of aquatic systems have been drawn: the paradigm of lakes as microcosmos or integrated ecosystems, paradigm of lakes as experimental systems, paradigm of lakes as chronicles of natural history etc.
Tourism and Archaeology: Back to Origins
Cristina P?TRA?CU,Florin FODOREAN,Ioan FODOREAN
Journal of Settlements and Spatial Planning , 2011,
Abstract: Archaeological tourism is an alternative form of cultural tourism, which aims to promote the passion for history and the preservation of historical sites. Unfortunately, today, in Romania, there is not a real connection between archaeology and tourism and there are only few sites exploited for tourism. The interests between archaeology and tourism due to the preservation and the capitalization of the historical remains, generates, in fact a sustainable form of tourism. From this point of view the attractiveness of the sites is based on the idea of preserving the “spirit of place” by safeguarding of tangible and intangible heritage. This is the most important in capitalizing the Romanian rural space, too. A fascinating subject related to archaeological tourism is Roman archaeological remains. In this paper we will make a classification of some roman archaeological sites by the level of importance for tourism. This sites are all situated in rural area: the milestone from the Roman period situated in Aiton Village, the rural settlement from the Roman era, the aqueduct and the Roman road from Cop ceni and the Roman camp, the Roman road, the temples and the possibility for a touristic site museum from Tibiscum . Finally, the paper will consider three sites near Cluj-Napoca: Dealul Lomb (a Roman villa), Polus Centre area (the remains preserved in situ) and the S ndule ti settlement (Roman remains, near the spring of Cop ceni which was captured in the Roman era, too).
The Analysis of Land Use Based on CORINE Land Cover in the Romanian Part of the Tisa Catchment Area
RAULARIAN RUSU,TITUS MAN,IOAN FODOREAN,CIPRIAN MOLDOVAN
Romanian Review of Regional Studies , 2010,
Abstract: The analysis of the land use structure of the 13 counties of the Romanian part of Tisa catchment area has been made according to the 2000 edition of CORINE Land Cover, while the 1990 edition has been used for comparative purposes. Out of the total area of 8,269,229.48 hectares, the forests cover 37.92%, the arable lands 35.02% and the grasslands 17.97%. The other types of land use have lower weights, such as the continuous and discontinuous urban fabric 4.81%, the orchards 1.10% and the vineyards 0.98%. In the category of forests, the following types of land use are included: broad-leaved forests, which form the majority (24.72%), coniferous forests (6.22%), mixed forests (3.46%) and transitional woodland-shrub areas (3.52%). The forests are mainly located in the Carpathians and the hills. The non-irrigated arable lands (23.50%) are predominant within the arable lands. They lie mostly in the Western Plain and in the basins and corridors of the Transylvanian Depression and the Western Hills. The analysis of the dynamics of the land use structure between 1990 and 2000 indicates a relative stability in the case of forests, a decrease of arable lands and an increase of grasslands.
Multi-Phase Synchronous Motor Solution for Steering Applications
Arthur R. Matyas;Karoly A. Biro;Daniel Fodorean
PIER , 2012, DOI: 10.2528/PIER12060507
Abstract: This paper presents the analysis of a six-phase permanent magnet synchronous machine dedicated for electrical power steering system applications. The motor design is briefly described, as well as the construction of the studied motor. The study is validated by finite element method and via experimental results. Some simulated results prove the machine's capability to work in faulty conditions. The machines performances are validated experimentally though scalar control.
Daylight Savings Calculation Technique for Smart Buildings  [PDF]
Dariusz Kacprzak, Ioan Tuleasca
Intelligent Control and Automation (ICA) , 2013, DOI: 10.4236/ica.2013.41014
Abstract:

This publication presents a technique of quantifying energy savings due to daylight. The technique is designated to be used in smart buildings or similar applications where daylight harvesting is welcomed. The technique is divided into three stages. In the first stage an optical sensor is evaluated for its P (power)-E (illumination) response characteristics. In the second stage the calibration of room properties is carried out. In the final stage photometric calculations are performed, and energy savings are calculated. The major advantage of the proposed approach is to determine energy savings during the design stage of a building, not after the building construction or retrofitting. The information obtained from the calculations is useful for investors, future tenants and environmentalists.

Raman Spectroscopy Cell-based Biosensors
Ioan Notingher
Sensors , 2007, DOI: 10.3390/s7081343
Abstract: One of the main challenges faced by biodetection systems is the ability to detectand identify a large range of toxins at low concentrations and in short times. Cell-basedbiosensors rely on detecting changes in cell behaviour, metabolism, or induction of celldeath following exposure of live cells to toxic agents. Raman spectroscopy is a powerfultechnique for studying cellular biochemistry. Different toxic chemicals have differenteffects on living cells and induce different time-dependent biochemical changes related tocell death mechanisms. Cellular changes start with membrane receptor signalling leading tocytoplasmic shrinkage and nuclear fragmentation. The potential advantage of Ramanspectroscopy cell-based systems is that they are not engineered to respond specifically to asingle toxic agent but are free to react to many biologically active compounds. Ramanspectroscopy biosensors can also provide additional information from the time-dependentchanges of cellular biochemistry. Since no cell labelling or staining is required, the specifictime dependent biochemical changes in the living cells can be used for the identificationand quantification of the toxic agents. Thus, detection of biochemical changes of cells byRaman spectroscopy could overcome the limitations of other biosensor techniques, withrespect to detection and discrimination of a large range of toxic agents. Furtherdevelopments of this technique may also include integration of cellular microarrays forhigh throughput in vitro toxicological testing of pharmaceuticals and in situ monitoring ofthe growth of engineered tissues.
The Permittivity for Anisotropic Dielectrics with Permanent Polarization
Ioan Bere
PIER M , 2012, DOI: 10.2528/PIERM11121604
Abstract: A new permittivity is defined for anisotropic dielectrics with permanent polarization, which allows obtaining simple connections between the quantities of electric field. As an application, using the defined quantity, we will demonstrate advantageous forms of the refraction theorems of the two-dimensional electric field lines at the separation surface of two anisotropic dielectrics with permanent polarization, anisotropic by orthogonal directions.
The Role of New Technologies on Contemporary Communication
Tudor IOAN
Risk in Contemporary Economy , 2012,
Abstract: Human communication, in its various forms and systems of signs has allowed for the addition of cultural values along the course of human history, through their conservation and transmission from one generation to the next, a process which confers on culture its cumulative character. Information, specific to the human world, has, itself, a particular role. The information field, generalized, changes within us the feeling of time. Man’s relationship with nature, instead of being just lived, practiced in an obscure manner, gains a statute of stability, of consistency, which transforms it into a reality with its own laws and orderly permanence. Technical activity, edifying the world of technical objects and generalizing the objective mediation between man and nature, links man to nature through a connection that is much richer and well defined than that of the specific reaction of collective labor. The transformations of contemporary communication due to new technologies imply and insistently demand modifications especially in the area of human adaptability.
Credit Risk Management
Viorica IOAN
Risk in Contemporary Economy , 2012,
Abstract: The bank is exposed to credit risk, the risk of not being able to recuperate the debtor claims as a result of the activity of granting loans to the clientele. Also, credit risk may manifest due to investments in other local and foreign credit institutions. Credit risk may be minimized through the careful evaluation of credit solicitors, through their monitoring along the duration of the loan and through the establishing of risk exposure limits, of significant risk margins as well as the acceptable balance between risk and profit.
