Ultrashort laser pulses are finding increasing applications in biology and medicine. Such pulses can be used directly or after non-linear modification. Direct utilization includes propagation studies in scattering media with applications in optical mammography, dosimetry for photodynamic therapy and species concentration assessment. Intense continua of electromagnetic radiation of very brief durat

We compute the Cramér–Rao lower bounds for determination of isotropic permittivity and permeability in slabs using reflection and transmission data. The results apply to three common measurement situations: free space, rectangular waveguides, and coaxial waveguides. The bounds depend only on the available data and not on the actual inversion method used, making them suitable to evaluate a particul

Tannerella forsythia is a poorly studied pathogen despite being one of the main causes of periodontitis, which is an inflammatory disease of the supporting structures of the teeth. We found that despite being recognized by all complement pathways, T. forsythia is resistant to killing by human complement, which is present at up to 70% of serum concentration in gingival crevicular fluid. Incubation

Popular Abstract in Swedish Många människor tillbringar en stor del av dygnet på en arbetsplats, vilket innebär att det är en plats och en tid inte bara för arbete utan också för sociala relationer samt för mat och dryck. Maten, vare sig det handlar om lunchen klockan tolv, eftermiddagsfikan klockan tre eller chokladbiten under nattskiftet, bidrar till att skapa pauser i arbetet. Arbetsplatsen kanMany people spend hours in a workplace every week and food and drink play a central role in providing nutrition and energy and help to create breaks during the working day. However, meals are something more than the food consumed. This dissertation focuses on the meal at work, where the meal is surrounded by special circumstances when it comes to time, place and social relations, as well as the fo

We present a computational tool to develop an exhaust gas recirculation (EGR) - air-fuel ratio (AFR) operating range for homogeneous charge compression ignition (HCCI) engines. A single- cylinder Ricardo E-6 engine running in HCCI mode, with external EGR is simulated using an improved probability density function (PDF)-based engine cycle model. For a base case, the in-cylinder temperature and unbu
