Convection-diffusion-reaction and transport-flow problems motivated by models of sedimentation: some recent advances

The sedimentation of a suspension is a unit operation widely used in mineral processing, chemical engineering,wastewater treatment, and other industrial applications. Mathematical models that describe these processes and may be employed for simulation, design and control are usually given as nonlinear, time-dependent partial differential equations that in one space dimension include strongly degen

Dignity as a guiding principle for family care partners in the care of an old relative with dementia

Aim: There is a growing number of older people (65+) with dementia, and many family care partners are involved in making help-seeking choices. The aim of this study was to reveal how family care partners with an old relative with dementia proceed in the name of dignity in their desire to secure the best care possible while still maintaining their own dignity. Methods: Data were collected in 2009–2

The occupation-based intervention REDO™-10 : Long-term impact on work ability for women at risk for or on sick leave

Background: Stress-related disorders are increasing in western societies and are the main reason for sick-leave in Sweden. Previous research justifies occupation-based interventions to increase health and work ability. Aim: To investigate if the occupation-based intervention ReDO™-10 predicts work ability for women at risk for or on sick-leave. Material and Methods: A longitudinal cohort study des

Specific amino acid substitutions in β strand S2 of FtsZ cause spiraling septation and impair assembly cooperativity in Streptomyces spp.

Bacterial cell division is orchestrated by the Z ring, which is formed by single-stranded treadmilling protofilaments of FtsZ. In Streptomyces, during sporulation, multiple Z rings are assembled and lead to formation of septa that divide a filamentous hyphal cell into tens of prespore compartments. We describe here mutant alleles of ftsZ in Streptomyces coelicolor and Streptomyces venezuelae that
