1. 1. Teachers’ Assessment and grading Practices in upper secondary Science Classrooms in Sweden : The Teachers’ and Students’ Perspectives

   Författare :Maria Gomez; Pedagogik; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Assessment and Grading practices; Science Classrooms; Learning Sciences; Learning; Natural Sciences; Upper-Secondary School;

   Sammanfattning : This dissertation acknowledges that accountability of educators for the grades they assign is a part of the foundation for a meritocratic society, based on fairness in judging merit and, therefore, in assigning grades. In this view, any grade obtained by any student must be both reliable and valid. LÄS MER

3. 2. Calcium channel activity and force regulation in smooth muscle: Effects of polyamines and growth stimulation

   Författare :Maria Gomez; Kardiovaskulär forskning - immunitet och ateroskleros; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; verapamil; tissue culture; portal vein; patch-clamp; calcium; spermidine; spermine; polyamines; excitation-contraction; smooth muscle; calcium channel; ionomycin.; Physiology; Fysiologi;

   Sammanfattning : The initial signal for contraction in smooth muscle is an increase in [Ca2+]i. Ca2+ ions can either enter the cytosol from the extracellular medium or be released from intracellular stores. Voltage-operated Ca2+ channels (VOC) play a dominant role in the activation of smooth muscle contraction. LÄS MER

4. 3. Electricity access for human development in the Brazilian Amazon

   Författare :Maria F Gómez; Semida Silveira; Elisabeth Ilskog; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electricity access; human development; Amazon region; SRA - Energy; SRA - Energi;

   Sammanfattning : Electricity access is widely recognized as a driver of development. The Brazilian government has incorporated this principle into its national rural electrification program, Luz Para Todos (LPT – Light for all), which has already benefited more than 14 million people in the country since its inception in 2003.
