Skadar Lake,the largest lake on the Balkan Peninsula,is famous for a wide range of endemic and rare,or even endangered plant and animal *** anthropogenic pressures have,however,influenced the fragile equilibria of the lake ecosystem,with metal pollution as one of the primary ***,this study investigated spatial distribution of metal pollutants in the water and sediment phase of Skadar Lake,and anthropogenic and environmental factors affecting this distribution.A sieving analysis showed that sediment in Skadar Lake is mainly distributed in the three smallest fractions(colloid,clay and silt).Eleven metals were analyzed in the lake surface and bottom water,and only six of them were detected:potassium,magnesium,calcium,nickel,aluminum and *** were all present at low *** contrast,sediments contained elevated levels of some metals with concentrations between 28.1-126.8 mg kg-1for Ni,23.6-79.2 mg kg-1for Cr,9.2-36.9 mg kg-1for Cu,199-878 mg kg-1for Mn and 9.6-23.1 g kg-1for *** exceeded consensus-based guidelines for safety towards freshwater dwelling *** organic matter content of the sediment fluctuated between 4.7 and 21.5%.No correlations were found between metal concentrations,organic matter and sediment particle size fractions,suggesting that the latter are not the main factors controlling metal accumulation in Skadar Lake.

The kinetic method for the determination of phosphate microamounts was described. The developed method is based on catalytic effect of phosphate on sodium pyrogallol-5-sulphonate （PS） by dissolved oxygen. The reaction was followed spectrophotometrically by measuring the rate of change in the values of the absorbance of the oxidation product at 437 nm. The optimum reaction conditions are PS （0.44×10^-3 mol·L^-1） and HClO4 （3.6×10^-6 mol·L^-1） at 25 ℃. Following this procedure, phosphate can be determined with a linear calibration graph up to 0.23 μg·mL^-1. The interference effect of several species was also investigated and it was found that the most common cations and anions did not interfere with the determination. The developed procedure was successfully applied to the determination of phosphate in natural waters and soil.

The neurorehabilitation is a term that relates to methods and technologies for maximising the functioning of impaired sensory-motor mechanisms in human after central nervous system (CNS) injury (e.g., Spinalcord injury, and stroke). Maximising function relates to developing new sensory-motor pathways and CNS strategies that could benefit from the available, yet unused sensory-motor mechanisms. The CNS provides the basis for structuring neurorehabilitation activities to promote and enhance recovery of function following the injury

The paper is based on the autobiographic-essayistic book Istanbul： Memories of a City written by Orhan Pamuk. lstanbul as a typical old capital shapes the lives of its citizens by its spirit, culture, and imperial past. On the other hand, it is a city that lives with specific sentiments--the sense of defeat and loss, melancholy and pain because of the lost power and glory. The author analyzes Pamuk＇s vision of his native city created on the basis of the real scenes and imaginary, the truly lived experiences and fiction. The paper is also concentrated on the deeds of the Turkish and European writers that had made a great contribution in Pamuk＇s synthesis of the East and the West, the past and the present and authentic permeation of cultures he has achieved writing about Istanbul.

The purpose of this exploratory paper is to try to envision how corporate governance systems and practices are evolving and what eventually determines the forms they take and the functions they perform. Practical implications especially concern different consequences that recent global economic crisis has imposed on regulatory, business, and social aspects of corporate governance. In order to encompass different approaches to this ongoing issue, the author takes into account mainly theoretical contributions that address the issue from the following perspectives： interrelations between product market competition and corporate governance, assessment of capital market pressures on corporate governance; relation between labour market and corporate governance; and actors influencing corporate governance changes in national systems of corporate governance. Since the viability of any corporate governance system and practice, at national and international levels, depends on their ability to respond to both market pressure towards competitiveness and diversified requirements by influential social, political, and economic actors of change, the author suggests that all groups of factors should continue to be in the focus of future researches. On the other hand, as global economic crisis differently affects different countries and businesses, it is of particular importance for those that shape corporate governance policies and practices to be aware of the deep relatedness between corporate governance, on the one hand, and economic, social, and environmental aspects of growth and development, on the other hand.
