Impact of weather-climatic parameters on agricultural productions in Dolj County/Romania
FLORINA CRISTINA ROSCA
Cinq Continents , 2012,
Abstract: El impacto de los parámetros climáticos para el tiempo en producciones agrícolas en el Condado de Dolj. Para una evaluación objetiva de las condiciones agrometeorologicas existentes en el área, en términos de su potencial agroproductivo, aparecio la necesidad de un estudio comparativo sobre las temporadas de crecimiento agrícolas y en el rango de 1980-2008, en el condado de Dolj. El régimen de agua de las plantas junto con el tratamiento térmico son algunos de los factores determinantes del rendimiento del metabolismo normal de la planta de cuerpo entero, teniendo de esta manera un papel fisiológico especial.

ILLEGAL MIGRATION-CONCEPTUAL DELIMITATIONS
CRISTINA FLORINA POPESCU (PANAIT)
Challenges of the Knowledge Society , 2013,
Abstract: Illegal migration is a mobile phenomenon, which ignores national borders, a threat that originates outside the community and extends to Western societies. This phenomenon is becoming larger and irregular migrants are often in a precarious situation and exposed to the criminals involved in various manifestations of organized crime. The future risk factors of the illegal migration are the demographic bomb, because the population is decreasing in European countries and increasing rapidly in poorer countries, droughts, floods, deforestation, that cause conflicts between climate refugees , extreme poverty, totalitarian regimes, epidemics, can trigger millions of people, the elderly and the working population imbalance which leads to the permanent import of immigrants To combat this phenomenon, states must engage and cooperate with each other. Measures taken by states must balance their integration policy for immigrants, legally residents and asylum policy to comply with international conventions. Also, states must adopt anti-immigrant policies, consisting of subordination visa policy to the interests of international security and exchange of information and, not least, to continue the Schengen process, as a value of humanitarian law applied in the field. The aim of the research is to characterize this dangerous phenomenon for the society and the goal is to identify strategies to combat illegal migration.
FINANCIAL CRISIS, SUBSIDIES AND CLIMATE CHANGE IN THE EQUATION OF SUSTAINABLE DEVELOPMENT
FLORINA BRAN,ILDIKO IOAN,CRISTINA POPA
Aerul ?i Apa : Componente ale Mediului , 2011,
Abstract: Financial crisis, subsidies and climate change in the equation ofsustainable development. An irreducible situation such as the contemporary financialcrisis creates the premises of major overthrow in decision criteria. Meanwhile,significant progresses in overcoming the ecological crisis, fueled mainly by the climatechange are also in relation with such changes. This convergence is easy to be observeddue to logical connections. If its existence was noticed at decisional levels is theoverarching question that structure the paper. Since the answer is positive, there areexplored the visions and plans of measures developed within this confrontation. Thereis applied a global approach and that is why each discussion considers also theimplications of economic globalization and of global environmental action as influencefactors on the path and direction of change.
CLIMATE CHANGE – BETWEEN COSTS AND BENEFITS
CARMEN VALENTINA R?DULESCU,FLORINA BRAN,CRISTINA POPA
Aerul ?i Apa : Componente ale Mediului , 2011,
Abstract: Climate change – between costs and benefits. At global and regional levels the effects of climate change start to show up. While some of the countries make efforts to alleviate these effects and to find solutions, others are facing economic or political restrains that prevent them in applying the principle of common responsibility. The complex social, economic, and environmental implications of climate change’s effects focused a growing part of research on the analysis of costs and benefits. Although controversial, one of the methods used – the cost-benefit analysis – revealed that in most of the cases the prevention costs are lower than the costs of inaction. Prevention measures bring benefits by anticipating the impact and minimizing the risks for ecosystems and economy. The paper presents in its first part the controversies regarding the cost-benefit analysis, and continues, in the second part, with estimations on costs and benefits of certain policy instruments that target emission reduction.
The Ecological and Economical Performances in the Forested Area – a Need for the Future
Florina BRAN,Ioana Maria GHIDIU-B?TA,Cristina CIOVICA
Journal of Knowledge Management, Economics and Information Technology , 2012,
Abstract: The forests are indispensable for the natural balance on Earth. Without the existence of the forest the life is not possible because this ecosystem provides many goods and services. The many clear cut forest surfaces have led to the lack of balance of ecosystems causing risks for the environment. The globalization promotes multinational companies, which have an important role in the exploitation of the forest. Because of the many advantages, the forest must be protected from the bad influence of the globalization, a thing possible due to the fact that the world is heading to a new economic order. The paper presents the situation of the forests in Romania for the 2005-2007.
Nanocomposites Based on Conducting Polymers and Functionalized Carbon Nanotubes with Different Dopants Obtained by Electropolymerization  [PDF]
Florina Branzoi, Viorel Branzoi
Journal of Surface Engineered Materials and Advanced Technology (JSEMAT) , 2014, DOI: 10.4236/jsemat.2014.43020
Abstract:

Nanocomposite films based on poly (3,4-ethylenedioxy thiophene) (PEDOT), functionalized single-walled carbon nanotubes and different dopants were studied. It was fabricated by a simple oxidative electropolymerization method. The dopant substances used were SDS (Sodium dodecyl sulfate) and tiron (1,2-Dihydroxybenzene-3,5-disulfonic acid disodium salt hydrate). These nano-composite films were grown electrochemically from aqueous solutions such that constituents were deposited simultaneously onto substrate electrode. The synthetic, morphological and electrical properties of the nanocomposite films obtained were compared. Scanning electron microscopy (SEM) revealed that the composite films consisted of nanoporous networks of SWCNTS (single-walled carbon nanotubes) coated with polymeric film. Cyclic voltammetry (CV), electro-chemical impedance spectroscopy (EIS) and FT-IR spectroscopy demonstrated that these composite films had similar electrochemical response rates to pure polymeric films but a lower resistance and much improved mechanical integrity. The negatively charged functionalized carbon nano-tubes (CNTSF) served as anionic dopant during the electropolymerization to synthesize polymer/CNTSF composite films. The specific electrochemical capacitance of the composite films is a significantly higher value than that for pure polymer films prepared similarly. Using these composite films, the modified electrodes with improved properties were obtained. (In this paper, for simplicity, the SWANTs-COOH group will be noted CNTsF which means functionalized carbon nanotubes.)

Florina Branzoi, Viorel Branzoi
Open Journal of Organic Polymer Materials (OJOPM) , 2015, DOI: 10.4236/ojopm.2015.54010
Abstract: Electropolymerization and characterization of poly(3,4-ethylene dioxythiophene) (PEDOT) doped with functionalized single-walled carbon nanotubes (SWANTs) polyaminobenzene sulfonic acid (PABS) and different dopants were studied. It was fabricated by a simple oxidative electropolymerization method. The nanocomposite coatings have been prepared by using electrochemical methods from aqueous solutions, such that the components were deposited onto platinum electrode substrate. The morphology of composite films was analyzed by scanning electron microscopy (SEM). The electrochemical and physical properties of the resulting composites were evaluated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and Fourier transform infrared spectroscopy (FT-IR) techniques in 0.1 M LiClO4 aqueous solutions. The value of specific electrochemical capacitance of the composite films is considerably higher than that of the pure polymers films. The improved properties of the electrodes were obtained by using these composite films. The dopant substances used were sodium dodecyl sulfate (SDS) and 1,2-Dihydroxy- benzene-3,5-disulfonic acid disodium salt hydrate (tiron).
