  2. 1. Spatial modelling and simulation for disease surveillance

    Author : Mohammadreza Rajabi; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GISgeografiska informationssystem; Agent Based Modeling; spatial epidemiology; machine learning;

    Abstract : This thesis addresses the application of spatial approaches to disease surveillance and control from three different aspects. First, temporal trends, geographical distribution and spatial pattern of cardiovascular disease admission rates were explored on a national level in Sweden. READ MORE

  4. 2. Inter and intra-tumor models of somatic evolution in cancer

    Author : Mohammadreza Mohaghegh Neyshabouri; Jens Lagergren; Ben Raphael; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cancer progression models; MCMC; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : Cancer is a disease caused by the accumulation of somatic mutations in an evolutionary process. Mutations in so-called cancer driver genes provide the harboring cells with particular selective advantages and result in cancer progression. READ MORE

  5. 3. Novel clean-up, concentration and laser desorption/ionization strategies for mass spectrometry

    Author : Mohammadreza Shariatgorji; Leopold Ilag; Juan Astorga-wells; Bernhard Spengler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; ESI-MS; SALDI-MS; Electrocapture; Sample treatment; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Despite valuable advantages of mass spectrometry (MS) techniques they still have drawbacks that need to be overcome, notably their sensitivity to various kinds of interfering substances and associated difficulties involved in detecting signals from analytes present in trace quantities. Thus, high quality analytical data could be acquired by improving sample pre-treatment techniques and/or ionization methods to increase ionization yields and/or avoid the generation of unwanted ions.

  6. 4. Mechanisms of adhesive mixing for drug particle inhalation (Numerical investigation of the interplay between formulation variables)

    Author : Mohammadreza Tamadondar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Element Method; Agglomerate; Carrier Particle; Adhesive mixing; Dispersion; DPI-formulation;

    Abstract : Formulation of therapeutic dry powders for lung drug delivery via inhalation is done via adhesive mixing. In this process, micron-sized active pharmaceutical ingredient particles are blended with relatively coarse carrier particles until stable adhesive units of carrier and drug particles are formed.

  7. 5. Al-Si Cast Alloys - Microstructure and Mechanical Properties at Ambient and Elevated Temperature

    Author : Mohammadreza Zamani; Anders Jarfors; Sten Johansson; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si based casting alloys; elevated temperature; microstructural scale effect; Sr modification;

    Abstract : Aluminium alloys with Si as the major alloying element form a class of material providing the most significant part of all casting manufactured materials. These alloys have a wide range of applications in the automotive and aerospace industries due to an excellent combination of castability and mechanical properties, as well as good corrosion resistance and wear resistivity.
