both heliophysical and anthropogenic (wastewater) effects on zooplankton biomass and abundance of the imandra lake (the largest subarctic lake at kola peninsula, russia) were investigated during the 1990 - 2003 period. we used different indexes of solar activity (sunspot numbers and uv- radiation values) as heliophysical factors. information about uv- radiation values was derived from satellite...

During 3 research cruises in the southern North Sea between 1986 and 1988 dab Limanda l imanda L. were examined for liver anomalies. Macroscopic and microscopic descriptions include different color irregularities and neoplastic changes. The frequency of the various liver lesions observed were calculated, the influence of fish length, sex, and season on their occurrence studied, and their geogra...

Rey/Akıl Taraftarlığı zihniyetinin temsilcilerinden Ebû Hanîfe ve İmam Mâtürîdî; fıkıhta Hanefilik itikatta Matüridiliğin oluşmasına öncülük etmiş iki önemli düşünürdür. Onlar Mürcie’nin itikadî fıkhî konulardaki görüşlerinden etkilenmiş olup dinde kolaylık, akılcılık imanda eşitlik ilkelerini düşünce sistemlerinin merkezine yerleştirmişlerdir. Muhaliflerince amelleri önemsemeyip değersizleştir...

nature has always proven that it is able to overcome its problems. however, humanmanipulation has led to environmental degradations. the dryness of a thousand-year urmia lake(a brine water lake in iran) is an example of environmental degradation that happened due tosuccessive droughts and construction of dams on the basin of this lake. this study examinesmethods for the revival of urmia lake by...

According to the water resources and climate change and challenges of Urmia Lake basin, which is the discharge and final destination of North West Rivers, a model was presented. Due to climate change and water resources in river basin such as rainfall, climate change in basin that has direct impact on evaporation over water catchment areas and lake water, this model can be provided. In addition...
