The pronounced increase in the cycling and deposition of biologically reactive dissolved inorganic nitrogen (DIN) over large areas globally not only cause increased concentrations of DIN in surface waters, but it will also affect nutrient ratios in rivers, lakes and coastal areas. This review addresses the flux and fate of DIN, focusing NO3 in lakes of boreal and alpine catchments. Not only DIN...
Receiving coastal waters and estuaries are among the most nutrient-enriched environments on earth, and one of the symptoms of the resulting eutrophication is the proliferation of opportunistic, fast-growing marine seaweeds. Here, we used a widespread macroalga often involved in blooms, Ulva spp., to investigate how supply of nitrogen (N) and phosphorus (P), the two main potential growth-limitin...
ahmed mahmud is one of the most prominent iranian writers in recent decades. he began his work with writing the short story entitled “sob mishe” and continued with” mool”. he received a position among top rank writers with writing the novel hamsayeha. many critics have criticized and studied his works and often dealt with the content of his stories. the paper first addresses form and structur...
as the most significant religious resource for muslims, quran has always attracted the attention of many muslim and non-muslim scholars. so far many translators, with various intentions, have translated this holy book. a group of these translators pretended to be muslims, while in fact they were strong enemies of islam, and their real intention was to change the realities of this holy book and ...
Çingiz Han’ın 1227 yılında ölümünden sonra hayatta olan en yaşlı oğlu olarak Çağatay Han (1227-1241) tarafından kabaca Maveraünnehr topraklarını ihtiva eden bölgede büyük bir devlet teşekkül ettirilmişti. Moğol kabile kanunları (Yasa)’nın korunması ve uygulanmasından sorumlu Han, hayatı boyunca İslam akidelerine karşı olmuş Müslümanları dinî bakımdan son derece müşkül durumda bırakmıştı. Diğer ...
Given H a real Hilbert space and Φ : H → R a smooth C function, we study the dynamical system (DIN) ẍ(t) + αẋ(t) + β∇Φ(x(t))ẋ(t) +∇Φ(x(t)) = 0 where α and β are positive parameters. The inertial term ẍ(t) acts as a singular perturbation and, in fact, regularization of the possibly degenerate classical Newton continuous dynamical system ∇Φ(x(t))ẋ(t)+∇Φ(x(t)) = 0. We show that (DIN) is a well-pos...
In aquatic ecosystems, carbon (C) availability strongly influences nitrogen (N) dynamics. One manifestation of this linkage is the importance in the dissolved organic matter (DOM) pool of dissolved organic nitrogen (DON), which can serve as both a C and an N source, yet our knowledge of how specific properties of DOM influence N dynamics are limited. To empirically examine the impact of labile ...
