This study analyzed the metabolic potential of some functional groups of bacteria in aquatic urban systems and evaluated the abundance of communities of total heterotrophic bacteria in the water in relation to the monitored physico-chemical factors. The results obtained showed seasonal differences, especially in spring. The high values of the abundance of heterotrophs in winter are related to human activity at the sampling stations. Screening for four types of extracellular hydrolytic enzyme with potential for degradation of organic matter (amylases, lipases, proteases and cellulases) led to the conclusion that lipolytic bacteria were dominant in the studied ecosystems, while proteolytic bacteria were observed in low numbers, but were present in urbanized areas. The presence of cellulolytic bacteria is correlated with the development of macrophytic vegetation. The aim of the present study was oriented towards the evaluation of the anthropogenic input in several lakes surrounding Bucharest in the Nord-Eastern region. These urban ecosystems are generated as a requirement of city development. The microbiological and general enzymatic approaches generated some novel results concerning the pollution degree of aquatic urban ecosystems and could be considered as a platform for further investigation.

’’Ambigen" by Octav Şuluţiu is a diary type novel, a subjective, first person confession like the ones of Max Blecher, Mihail Sebastian. Character-narrator explores, analyzes his deepest, hidden emotions, feelings, weaknesses, defects, demons, impossible loves,visions of the world. It is actually an investigation of the subconscious states of a man-woman who hides two genders: male and female, hence the dual nature of the character, bigender. There is an inner battle between the character's masculine and feminine side.The woman inside him needs another woman he can own and the man inside wants a strong woman who can have the male features that he lacks.

Authenticity is closely related to the expression of sincere feelings, thoughts, without regard to any rule. Camil Petrescu is a follower of lucidity and absolute sincerity, everything must be under the control of reason, including the most ineffable impulses.The whole work of the writer is an act of existence, Camil Petrescu being trapped in the game without escape of the iele, just like his heroes, searching relentlessly the absolute idea which necessarily involves substantiality.This authenticity blends with the polemic that opposes the writer's own vision to an other vision which seems to him

The need to synthesize qualitative research in order to inform fields of study has been highlighted as a critical imperative in recent years. Since that time, there have been a number of attempts to identify methodological approaches to achieving such a goal. Despite some notable efforts in this regard, the metasynthesis research approach continues to be somewhat elusive with regard to its steps and procedures. The authors of this article describe their experience conducting a metasynthesis of qualitative research regarding transformation in chronic illness and disability. The particular emphasis of the article will be the practical strategies and procedures that assisted them in conducting the project in a rigorous and meaningful way. The authors emphasize the need for continued dialogue about strategies and procedures in metasynthesis that will aid researchers who are contemplating this complex research approach.

The present paper deals with biological studies of natural salt lakes located in the Romanian plain. There were investigated for first time the halophilic microorganisms (bacteria and archaea) and also phyto- and zooplankton species in relation with physical-chemical parameters as control factors. The chemical composition of all tested lakes is marked by the abundant presence of chlorides (sodium, magnesium, potassium) and also some relatively important concentrations of aluminium and strontium detected in the particular case of Ocnele Mari. The biological diversity was represented by several types of archaea and halophilic bacterial species and some species of cyanobacteria and diatoms. There were also identified ciliates, rotifers and copepods mainly in the samples taken from Amara and Balta Albă. These lakes are considered hyposaline, because total chloride concentrations do not exceed 20 g L-1 and sodium appears to be absent. The results revealed the presence of magnesium and calcium ions and a chloride content that influences the phytoplankton and zooplankton diversity in these saline environments.

The aim of this paper is to identify the general characteristics of structure and functioning of coenoses from a few anthropogenic habitats: sterile dumps, sterile ponds, afforestations. Ten sites were studied; four of them are natural habitats and their analysis is necessary for comparisons. The analysis of data is directed to epigeic invertebrate fauna but it is also commented the vegetation status, for a better reflection of the structure and functions of these coenoses. In anthropogenic habitats both vegetation and invertebrate fauna differ as structure and functioning in comparison with the adjacent natural areas and the slow evolution of vegetation influences the other coenotic components. The determining factor of this situation is human pressure: either the substrata are radically modified or the level of primary producers is drastically controlled by humans, or both.

The paper aims to emphasize the long-term changes in the structure and ecological processes of planktonic communities in shallow lakes of the Danube Delta Biosphere Reserve as well as the consequences on the flows of goods and services these lakes offer to socio-economic systems. Under the eutrophication pressure, profound changes in biodiversity and energy flow were observed as compared to the reference period. The balance between submerged macrophytes and phytoplankton characterized the natural status of the Danube Delta lakes (1975 - 1980). This was changed by the eutrophication process with consequences on the entire food web structure. Phyto and zooplankton species richness decreased with 50%, with effects on the quality and quantity of production, as well as on the nutrient recycling rate. In Roșu Lake (a representative shallow lake used as case study), the phytoplankton and zooplankton biomass increased 50 and 8 times, respectively, due to increased nutrient supply and changes of micro/macro filter feeders ratio. A low level of increasing (1.7 times) has been recorded for the bacterioplankton biomass. The maximum impact of eutrophication (hypertrophic period) is characterized by the energy input via phytoplankton exclusively. Nutrient recycling rates by phytoplankton and zooplankton decreased 11 and 1.1 times, respectively as a result of structure and trophic relationship changes. Shift in the submerged macrophytes/phytoplankton ratio affected the composition of organic substrate with consequences on the bacterioplankton communities. Since 1991, due to economic changes in the Danube basin, a trend of trophic state recovery of lakes has been registered, first observed at the level of phytoplankton communities. The responses at the level of phytoplankton communities consisted in increased nutrient recycling rates (without reaching the maximum capacity from the reference period). Till 2001, zooplankton kept the decreasing trend started in 1975, whereas bacterioplankton registered significant values of nutrient recycling that indicate the prevalence of degradation processes in the detriment of accumulation in self-biomass.

Communism thought that the literature and the writers were their instruments. Few were those who had the courage to write what they felt and express their outrage at the misery that surrounded them. Others were content just to express their feelings, to put on paper their own life experiences or even create a Paradise, a world different from the one in which they lived. Through his psychological and erotic prose, under the sign of authenticity, Anton Holban tried to analyze the depths of the self, and to analyze also those around him. [ABSTRACT FROM AUTHOR]

This would affect the proper functioning of institutions, both parties feeling the need to succeed, to have recognition, inclusion, control, harmony. Communication maintains mutual cooperation and properly manages the various problems that may rise and create a proper climate conduct of the business. [ABSTRACT FROM AUTHOR]
