The aim of the paper is to analyse the influence of environment factors on the capture and fish communities structure from Danube, between Siret River and Prut River mouth. Fish were collected from April to December 2011 in four fishing areas. During the year, 6027 kg, respectively 4805 fish of twenty three breeds were collected. Cyprinidae, the dominant family, 60.87% in term of number of breeds, was represented by 14 breeds (Cyprinus carpio, Carassius gibelio, Barbus barbus, Abramis brama, Abramis sapa, Blicca bjoerkna, Leuciscus idus, Vimba vimba, Aspius aspius, Pelecus cultratus, Chondrostoma nasus, Ctenopharingodon idella, Hypophthalmichthys molitrix, Hypophthalmichthys nobilis). Other families had the following structure: Clupeidae (4.35%) with one breed (Alosa pontica), Acipenseridae (13.04%) with 3 breeds (Huso huso, Acipenser stellatus, Acipenser ruthenus), Percidae (13.04%) with 3 breeds (Sander lucioperca, Zingel zingel, Zingel streber), Siluridae (4.35%) with one breed (Silurus glanis) and Esocidae (4.35%) with one breed also (Esox lucius). The highest capture was 2728.5 kg (45.29%), during the spring season (April- May), followed by autumn season (September -November), with 560.45 kg (9.29%). The water level and water flow showed high correlation with both number and total capture, respectively. [ABSTRACT FROM AUTHOR]

The paper is presenting some aspects regarding the structure of fish communities from 22 Km of predeltaic sector of Danube River, between the mouth of Siret River (km 155) and Prut River (Mm 72.5). The aim of the study is to assess the ecological status of the area, using the main ecological indices as abundance, dominance, constancy and ecological significance. From April to December 2011, in four fishing areas (km 150-151, Mm 77-78, Mm 76-77, Mm 74-74.5), 4805 fish of twenty three species, from six famillies, were collected. The best represented family is Cyprinidae with 14 breeds. The numerical abundance ranged between 2 fish/breed (zingel, common nase) and 2035 fish/breed (pontic shad). The pontic shad (42.35%), common bream (11.63%) and common carp (10.9%) are eudominant breeds, having the biggest potential in fish productivity. Pike-perch (75%), common bream (75%), common barbel (75%), vimbe (75%), white-eye bream (75%), asp (66.66%), prussian carp (66.66%), white bream (58.33%), common carp (58.33%), silver carp (58.33%) and sterlet (58.33%) are constant species with high adaptability. In term of ecological significance, Danube shad (14.11%), common bream (8.72%), common carp (6.36%) and common barbel (5.32%) are characteristic species. [ABSTRACT FROM AUTHOR]

Land surface temperature (LST) is an important indicator of the environment and is directly related to the physical, chemical and biological earth's surface. LST evaluation for each land use and land cover (LULC) is an important step in the study of ecosystems and the relationship within them. In this paper LTS were evaluated on LULC types using a satellite image Landsat 5 Thematic Mapper (TM) in the thermal infrared band. Identifying LULC in satellite image was achieved by supervised classification method into six classes using maximum likelihood, Mahalanobis distance and minimum distance algorithms. Overall accuracies were 86.67% and kappa statistics (KS) 0.84 for maximum likelihood, 80.83% and KS 0.77 for Mahalanobis distance and 68.33% and KS 0.62 for the minimum distance. Comparing temperatures, for each category LULC and each algorithm, were found slight significant temperature differences (1-3°C) for minimum distance algorithm over other algorithms. Results from the study area show that the forest and shrub has the lowest temperature (22.90°C, 22.67°C and 23.43°C) due to transpiration and evapotranspiration processes within it. Highest temperatures were found in uncultivated (27.86°C, 27.41°C and 28.96°C) due to direct exposure and lack of vegetation. [ABSTRACT FROM AUTHOR]

Background: Chronic diseases are major causes of morbidity and mortality in developed countries. Their effects can be mitigated by high quality evidence-based care, but this is not the norm in most systems. The Chronic Care Model (CCM) is an evidence-based policy response to this practice gap, which uses multiple strategies to promote the quality of chronic care. Objective: To review CCM with an ethical lens. Methods: We reviewed the published empirical and non-empirical articles of CCM to analyse the ethical underpinnings of this model. Results and conclusions: We argue that its principal ethical value lies in the institutional cooperation it builds between the stakeholders involved in health care services. First, we briefly describe CCM and argue that the pathways through which it aims to improve patients' health outcomes are not made explicit. Second, we argue that the potential of CCM to be more beneficent, compared with traditional health care systems, depends on its capacity to promote mutual trust between health care providers and patients. There is no evidence to date that the implementation of CCM enhances mutual trust between health care professionals and patients. Third, we argue that CCM seeks to enhance human agency, allowing increased expression of individual autonomy and increased respect for individuals thereby expanding human freedom and avoiding social discrimination. However, we review the communication patterns that characterize the model of doctor-patient relationship promoted by this model and argue that these communication patterns raise ethical concerns that may prevent the model from reaching its expected outcomes.

Danube shad is a fish with high economic and socio-cultural value for the human communities established in the Danubian-Pontic space. In Romania, shad fishery has a market value of about 1.5 million euro, with average annual catches of 200-500 tonnes. Biological material was collected during research surveys organized along the Black Sea coast, in 2012-2013, in spring season (March, April), summer (June, July) and autumn (September). Experimental fishing was done with fishing gillnets. Demographic structure of Alosa immaculata consists of generations of 2-5 years, dominated by generations of 3 to 4 years. The aim of this paper is to provide recent data regarding Alosa immaculata population along the Black Sea Coast considering that its biology is less known.

The synthesis and the study of some coordination polymers derived from the interaction of the acetylacetonate of Fe(III) with dinaphthylphosphinic acid, dinaphthylthiophosphinic acid and dinaphthyldithiophosphinic acid are presented. The methods applied for the study were chemical analysis, gel chromatography, Mössbauer and IR absorption spectroscopy, X-ray diffraction and thermogravimetric analysis from which the kinedic parameters of the thermal decomposition reactions were determined. The semiconductive properties of the synthesized compounds were also examined. Based on the obtained experimental data and on literature indications, the structural formulae of these compounds were assigned.
