    Abstract : Degradation of the hydrological regime is a pressing issue in the Ethiopian Highlands. It is one of the most rapidly degrading landscapes due to its topography and large amounts of annual precipitation. This problem has been exacerbated through anthropogenic influence from land use/land cover (LULC) and climate change. READ MORE

    Abstract : Sjön Hjälmaren är belägen där Örebro, Västmanlands och Södermanlands län möts. Sänkningen av denna sjö mellan 1878 och 1888 framstår som ganska spektakulär, inte minst från ett nutida perspektiv. Vattennivån sänktes med strax över en meter och nästan 20 000 hektar tidigare våt- och ängsmark kunde omvandlas för åkerbruk. READ MORE

  6. 15. Characterization of the Electrical Resistivity and Water Sorption Properties of a Semiconducting Swelling Tape

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Maria Nicte Polanco Olsen; [2018]
    Keywords : ;

    Abstract : I närvaro av fukt och lokaliserade fältförbättringar kan vattenträd utvecklas inom polymerisoleringen av HV subsea kraftkablar. Vattenträd tenderar att växa obemärligt och försämra isolationsegenskaperna med tiden. Fuktigheten i isoleringen kan effektivt reduceras genom applicering av halvledande svällningsband. READ MORE
