Abstract: The urban ecosystem is marked by the presence of natural factors, with a supporting role, and anthropic ones, which are interdependent and ensure for their inhabitants a different qualitative standard of life. The aim of the study is to highlight the implications of pollution phenomenon, specific for any urban ecosystem, in its sanogenesis state in the analyzed area. For reaching this goal, there have been processed databases concerning the quality of air, water, amount of generated waste and green spaces; measurements of the noise level have been made and collective waste collection points have been inventoried. The results have been processed and graphically represented by the soft Arc GIS 9.3 and by open-source statistical processing: R. The analyzed area consists of two residential districts in which the pollution must be reduced in order not to influence the sanogenesis state of the urban ecosystem, there being notified some factors, especially of chemical ones, that emphasize the phenomenon and produce hazards of the environment at a microregional level, without influencing the sanogenesis state as a whole.

Abstract: Considérations sur la qualité des sources d'eau souterraine dans la ville de Barlad. La ville de Barlad est alimenté avec l’eau potable qui provienne dans deux sources : souterraines et autres situées au surface. Aux derniers ans, la réduction de la longueur du réseau de distribution de l’eau dans la ville avec ~9%, a mené vers l’augmentation du nombre des utilisateurs de l’eau qui provienne de sources souterraines, c'est-à-dire les fontaines et les pompes, caractérises par une minéralisation haute. L’étude représente la première phase de l’étude qui veut mettre en évidence les variations imposées par la succession des saisons dans la région étudiée avecl’objectif de trouver les meilleures sources pour les habitants. Après récolter les échantillons d’eau, par les 44 sources souterraines, ont été déterminés les indicateurs de qualité de l’eau potable (en utilisant des méthodes électrochimiques, volumétriques et spectophotométriques). Puis les résultats ont été représentés avec ArcGis 9.3; en rélevant des dépassements pour certains indicateurs.

Ana Oi?te,Iuliana Breabn
Present Environment and Sustainable Development , 2010,
Abstract: This paper has the purpose of illustrating the state of the buildings and its impact on the environmental quality in North-West Ia i. The data were processed on the field with the help of questionnaires in 2008-2009 and focused on the roof type, number of levels, polystyrene isolation and other space usages. A classification of the buildings built before 1955 and after this year was done, too. This area was chosen as it contains residential quarters (Copou University, Super Copou, Sararie partially) in which a high standard of the environment quality is essential for its inhabitants.

Abstract: Lignocellulose is a generic term describing the main constituents in most plants, namely cellulose, hemicelluloses, and lignin. Cellulose is a glucose polysaccharide, hemicelluloses are polysaccharides with a backbone of different hexoses (glucose, mannose, galactose) and pentoses (xylan, arabinose), and lignin is a complex network of different phenyl propane units. The cellulosic materials are potential sources of ethanol. Steps of this process are saccharification of cellulose to reduce sugars, under enzymes action and to reduce sugars fermentation by yeast to obtain ethanol.The aim of this study is to examine the influence of substrateconcentration, temperature and pH upon enzymatic saccharification ofwaste cellulosic materials, based on office paper, newspaper andcardboard, in ratio of 1:1:1 (w/w) and reducing sugar accumulationdynamics in optimised conditions. The study has established optimalparameters: the ratio of enzyme:substrate as 0.5 EU/g substrate,temperature 48°C, pH 4.8 and addition of surfactant Tween 80 inproportion of 0.3 %, reported to the total volume of liquid. The reducing sugar yield was 35 mg reducing sugars/ g dry weight cellulosic waste.

Abstract: This study was aimed to evaluate the seroprevalence ofhepatitis B virus (HBV) infection in the county of Ia i, Romania, the possible risk factors of HBVtransmission and to apreciate the clinical features of the infection. METHODS: A cross-sectionalepidemiological study was conducted between july 2007- june 2008 among the adult populationof county of Ia i and was tried to identify the risk factors of HBV transmission. The sampleconsisted of 1200 adult subjects, registered on the list of six family physician praxis, three froman urban area and three from a rural area; it was used a questionnaire concerning the sociodemographiccharacteristics and potential risk factors. Serum samples were assayed for Ag HBsby 3rd generation ELISA. The subjects found with AgHBs positive completed their evaluation forindicators of liver disease (chronic hepatitis, cirrhosis or liver cancer). RESULTS: The HBsAgprevalence in adult population of county of Ia i was 5,2% (42 persons: 31 were inactive carriers, 9with chronic hepatitis, 2 with cirrhosis and none with liver cancer ). We found male sex, old age,intrafamilial exposure, serious accidents, history of acute hepatitis B, sexual risk behavior, dentaltreatment, tattooing as the major independent risk factors of HBV transmission, CONCLUSIONS:The overall HBV prevalence in the county of Ia i was 5,2%, similar to other cuntries of EastEuropean region. There are risk factors implicated in HBV infection. Optimal management ofHBV infection requires lifelong routine monitoring of all patients to assess progression of liverdisease, development of hepatocellular carcinoma, need for treatment, and response to treatment.
Promoter Sequences Prediction Using Relational Association Rule Mining

Evolutionary Bioinformatics , 2012, DOI: 10.4137/EBO.S9376
Abstract: In this paper we are approaching, from a computational perspective, the problem of promoter sequences prediction, an important problem within the field of bioinformatics. As the conditions for a DNA sequence to function as a promoter are not known, machine learning based classification models are still developed to approach the problem of promoter identification in the DNA. We are proposing a classification model based on relational association rules mining. Relational association rules are a particular type of association rules and describe numerical orderings between attributes that commonly occur over a data set. Our classifier is based on the discovery of relational association rules for predicting if a DNA sequence contains or not a promoter region. An experimental evaluation of the proposed model and comparison with similar existing approaches is provided. The obtained results show that our classifier overperforms the existing techniques for identifying promoter sequences, confirming the potential of our proposal.
CHARACTERISTICS OF ARIDITY CONDITIONS IN SOUTH DOBRUDJA

Abstract: Characteristics of Aridity Conditions in South Dobrudja. For most people, the arid and semi-arid lands are those where precipitation is low (less than 200 mm per year), and yet enough for supplying streams capable of temporarily carrying the debris resulted from weathering, but insufficient for encouraging the development of a vegetal cover meant to protect the soil blanket against eroding agents. The drought is a major and permanent climatic risk for the Dobrudja territory as a whole and for South Dobrudja in particular, a territory where hydrographic network is underdeveloped, streams are ephemeral, and semi-endorheic areas are well developed. When the period of moisture deficiency lasts longer, it can bring about a significant water imbalance, which results in crop losses or restrictions in water consumption, thus leading to a number of economic problems. Under the circumstances, the risk of aridity expansion is significant, this being the reason why a better water management system in Romania is urgently needed. In the last decades, the numerous specialty studies undertaken in the area have emphasized an intensification of the process of dryness, because atmospheric and pedological droughts have become more and more serious. Romania is a member of the United Nations Convention to Combat Desertification (UNCCD) and the World Meteorological Organization (WMO). It actively participates within the drought management network and the Drought Management Center for Southeastern Europe, which comprises 11 countries. The scope is to work together and exchange experience with the neighboring countries that have recorded positive results and acquired a rich experience in terms of drought management. The employment of appropriate pluvial indices in identifying the areas prone to aridity may prove to be convenient tool for finding practical solutions meant to mitigate the impact of this phenomenon on the local communities living in South Dobrudja.

Abstract: Part of a larger study regarding the genetic polymorphisms present in the human population of Romania, we have studied the frequency and transmission of AB0 blood groups in the B rlad region. We have investigated all the children born in B rlad (and resident in the region of birth) during a given year. AB0 blood groups were determined by the Blood Transfusion Centre of B rlad. The obtained frequencies (group 0 = 34,36% group A = 40,28%, group B = 17,46%, group AB = 7,90%) and sex ratios were concordant with previous values obtained for the romanian population. We are discussing various reasons for the slight regional differences of the AB0 blood group frequencies registered between different romanian regions. One of the most important causes of variation could be the materno-fetal incompatibility regarding AB0 blood groups. After performing a thorough family inquiry, our research proved a very limited importance of this mechanism as a generator of populational variability.
