Critical Evaluation of Alumino-silicate Systems : Thermodynamic Modeling of Alumina-containing Liquid and Solid Solutions
- 2008. - 1

Book (other academic/artistic)abstract
- Alumino-silicate systems are of great interest for materials scientists and geochemists. Thermodynamic knowledge of these systems is useful in steel and ceramic industries, and for understanding geochemical processes. A popular and efficient approach used to obtain a self-consistent thermodynamic dataset is called CALPHAD. It couples phase diagram information and thermochemical data with the assistance of computer models. The CALPHAD approach is applied in this work to the thermodynamic modelling and assessments of the CaO-Al2O3-SiO2, MgO-Al2O3-SiO2 and Y2O3-Al2O3-SiO2 systems and their subsystems. The compound energy formalism is used for all the solution phases including mullite, YAM, spinel and halite. In particular, the ionic two sub-lattice model is applied to the liquid solution phase. Based both on recent experimental investigations and theoretical studies, a new species, AlO2-1, is introduced to model liquid Al2O3. Thus, the liquid model corresponding for a ternary Al2O3-SiO2-M2Om system has the formula (Al+3,M+m)P (AlO2-1,O-2, SiO4-4,SiO20)Q , where M+m stands for Ca+2, Mg+2 or Y+3. This model overcomes the long-existing difficulty of suppressing the liquid miscibility gap in the ternary systems originating from the Al2O3-free side during the assessments. All the available and updated experimental information in these systems are critically evaluated and finally a self-consistent thermodynamic dataset is achieved. The database can be used along with software for Gibbs energy minimization to calculate any type of phase diagram and all thermodynamic properties. Various phase diagrams, isothermal and isoplethal sections, and thermochemical properties are presented and compared with the experimental data. Model calculated site fractions of species are also discussed. All optimization processes and calculations are performed using the Thermo-Calc software package.

Radiotherapy and clinical radiobiology of head and neck cancer
- 2018
-
Book (peer-reviewed)abstract
- Common factors that lead to treatment failure in head and neck cancer are the lack of tumour oxygenation, the accelerated division of cancer cells during treatment, and radioresistance. These tumour-related challenges and possible ways to overcome them are covered in this book, authored by three medical physicists and a clinical oncologist who explain how different radiobiological findings have led to the development of various treatment techniques for head and neck cancer. Novel treatment techniques as supported by current scientific evidence are comprehensively explored, as well as the major challenges that arise in the retreatment of patients who have already undergone a form of radiotherapy for primary head and neck cancer.

Acts of Aid : Politics of Relief and Reconstruction in the 1934 Bihar–Nepal Earthquake
- 2022
-
Book (peer-reviewed)abstract
- This socio-political history on the aftermath of the 1934 Bihar–Nepal earthquake explores disaster aid, relief, and reconstruction and the questions they give rise to about class, communities and inequality. The book traces disaster responses across the twentieth century in order to demonstrate how they were embedded in political processes transcending the event of the earthquake. Aid, relief and reconstruction mirrored political agendas and ideas that articulated both changes and continuities by the colonial state, civil society and international organisations. The impact of the earthquake and aid in its wake varied widely according to social groups, ethnicity and gender in the aftermath. By studying the effects of the earthquake on communities directly affected and society, the author argues that we can come closer to an understanding of the role political, social and cultural factors held in shaping resilience to natural disasters.

Alzheimers sjukdom och andra kognitiva sjukdomar. 3e uppl.
- 2011
-
Book (other academic/artistic)abstract
- Denna tredje upplaga ger en övergripande bild av kunskapsläget samtidigt som boken i dag har det största djupet och bredden inom demensområdet på den svenska marknaden. Samtliga kapitel har omarbetats och texterna har utökats samtidigt som en ny layout och färgbilder ger boken ett helt nytt läsarvänligt format. Boken vänder sig till samtliga grundutbildningar som berör demenssjukdomarna men också till alla de yrkeskategorier som på olika sätt möter personer med kognitiva sjukdomar. Även drabbade patienter och deras närstående har visat sig ha stort intresse av en lärobok där aktuell kunskap om sjukdomarna och deras konsekvenser belyses.
