Nutrients Export by Rivers to the Coastal Waters of Africa: Past and Future trends

We analyze past and future trends in nitrogen (N), phosphorus (P), and carbon (C) export by rivers to the coastal waters of Africa as calculated by the Global Nutrient Export to WaterShed (NEWS) models for the period 1970–2050. Between 1970 and 2000 the total nutrient export by African rivers increased by 10–80%. For future years (2000–2050) we calculate an increase in the total loads of dissolved forms of N and P, but decreasing trends for dissolved organic C and particulate forms of N and P. There are large regions that deviate from these pan-African trends. We explore the regional patterns and the underlying processes, in particular for the Nile, Zaire, Niger, and Zambezi. In the future, anthropogenic sources may, in large parts of Africa, become larger contributors to riverine nutrient loads than natural source

An Astrological Look into H.P. Lovecraft’s “The Call of Cthulhu:”A Celestial Telescope For Literary Analysis

University students often acquire a knowledge of a slew of literary criticisms for deeper exploration of compositions. Few, if any, literary criticisms can be applied with room for speculative scientific philosophical ways of thought. This brings the creative nature of analysis to a screeching halt– for what is more creative than a speculative-science? In this thesis I will give an introduction to key astrological ideologies. This paper will also work through how those ideologies could be applied analytically, academically, and professionally to literature. My aim will be to use one of H.P. Lovecraft’s main mystically- connotative works, “The Call of Cthulhu,” in order to create a paradigm for an astrological literary criticism. Creativity is the formation of something new and unique; consequently, analysis is a creative endeavor. A writer’s capacity to be creative and think beyond the realm of what is possible or not possible in the analytical approaches we have as English majors is exceedingly important. As a result of this logic, this paper will produce a framework by giving readers an introduction to astrology, a walkthrough of H.P. Lovecraft’s history, specifically regarding space, and an in-depth astrological analysis of “The Call of Cthulhu.

Millennium Ecosystem Assessment Scenario drivers (1970-2050): Climate and hydrological alterations

This study was carried out to support and enhance a series of global studies assessing contemporary and future changes in nutrient export from watersheds (Global Nutrient Export from Watersheds (NEWS)). Because hydrography is one of the most important drivers in nutrient transport, it was essential to establish how climatic changes and direct human activities (primarily irrigation and reservoir operations) affect the hydrological cycle. Contemporary and future hydrography was established by applying a modified version of a global water balance and transport model (WBMplus) driven by present and future climate forcing, as described in the Millennium Ecosystem Assessment scenarios (1970-2050). WBMplus represents a major upgrade to previous WBM implementations by incorporating irrigational water uptake and reservoir operations in a single modeling framework. Contemporary simulations were carried out by using both observed climate forcings from the Climate Research Unit of East Anglia (CRU) data sets and from Global Circulation Model (GCM) simulations that are comparable to the future simulations from the same GCM forcings. Future trends in three key human activities (land use, irrigation, and reservoirs operation for hydropower) were taken from the Integrated Model to Assess the Global Environment (IMAGE). The reservoir operation required establishing a realistic distribution of future reservoirs since the IMAGE model provided only the hydropower potentials for the different future scenarios

Cabri II Plus como herramienta para la enseñanza de las isometrías
