  1. 16. Marginal and Virtual Water for Sustainable Water Resources Management in Syria

    Author : Khaldoon A. Mourad; Centrum för Mellanösternstudier (CMES); []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Arid and semiarid Middle Eastern countries generally, and Syria in particular, face serious water shortage problems and challenges with water sustainability. Climate change, population growth, and economic development play a major role in decreasing available water resources per capita. READ MORE

  2. 17. Novel process integration opportunities in existing kraft pulp mills with low water consumtion

    Author : Cecilia Bengtsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; excess heat; evaporation; pinch technology; pulp and paper; energy; system consequences; process integration;

    Abstract : The economic opportunities for energy savings due to process integration of the evaporation plant have proven to be good in model mills with low water consumption. This is due to the fact that the temperature level of excess heat is higher compared with pulp mills with larger water consumption. READ MORE

  3. 18. Simulations of Evaporation Plants in Kraft Pulp Mills: Including Lignin Extraction and Use of Excess Heat

    Author : Marcus Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft pulp mill.; lignin extraction; heat integration; process integration; energy saving; excess heat; simulation; Energy-efficient evaporation; modelling;

    Abstract : In this thesis, evaporation plants at kraft pulp mills are simulated with the purpose of making them more energy efficient. The work is important since energy saving is assumed to be one of the major solutions for handling the world's energy demand in the future. READ MORE

  4. 19. Rain Water Harvesting (RWH) North of Iraq

    Author : Saleh Zakaria; Ahmed Hachum; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Rainwater harvesting is one of the methods that can ensure availability of water for winter crop in Iraq. Using this technique the excess rainwater (runoff) is stored in reservoirs of dams of different sizes. The water from these reservoirs can be used later when required to satisfy the crops requirements. READ MORE

  5. 20. Excess pore water pressure generation in crushed and fine granular materials under cyclic traffic loads

    Author : Tan Manh Do; Jan Laue; Hans Mattsson; Qi Jia; Ivo Herle; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Excess pore water pressure can develop in subgrades of railway and pavement substructures due to cyclic loading from heavy traffic, leading to the migration of fine particles into upper layers. This migration can clog pores and diminish the drainage capacity of upper layers,negatively impacting the long-term performance of sub-structures and service life, ultimately risking failure.
