11. Mixture Effects in Shell-and-Tube Condensers. Theory and Calculations
Abstract : Zeotropic mixtures have come into more frequent use as working fluids (refrigerants) in heat pumps and air conditioning equipment due to the phase-out of ozone-depleting substances. Substantial drop in performance for shell-side condensation in shell-and-tube condensers when replacing a pure fluid with a mixture has been reported in the literature. READ MORE

12. Homing Endonucleases and Horizontal Gene Transfer in Bacteria and Bacteriophages
Abstract : Homing endonuclease genes (HEGs) are selfish genetic elements that mediate their own super-Mendelian inheritance. This is mediated by the homing endonuclease cleavage of a HEG- allele followed by recombination-repair with a HEG+ allele.The majority of the HEGs are encoded in intervening sequences (IVSs).

13. Genomic Variation and Evolution of HERV-H and other Endogenous Retroviruses (ERVs)
Abstract : An exogenous retrovirus (XRV) that integrates into a germ cell may be inherited as a Mendelian gene; it becomes an endogenous retrovirus (ERV). The human genome consists of up to 8% HERVs. The gammaretroviral (ERV class I) HERV-H, with 926 members, is the largest ERV group. READ MORE

14. Molecular epidemiology of methicillin-resistant staphylococcus aureus : epidemiological aspects of MRSA and the dissemination in the community and in hospitals
Abstract : Methicillin-resistenta Staphylococcus aureus (MRSA) som bär på genen mecA, har förekommit och spridit sig över hela världen, främst i sjukhusmiljö, och orsakat utbrott av vårdrelaterade (så kallade nosokomiala) infektioner. Dessa infektioner kan inte behandlas med stafylokock-penicilliner och MRSA-bakterierna är ofta resistenta även mot flera andra grupper av antibiotika vilket medför att infektionerna ofta är påtagligt svårbehandlade.

15. Hidden Diversity Revealed : Genomic, Transcriptomic and Functional Studies of Diplomonads
Abstract : The diplomonads are a diverse group of eukaryotic microbes found in oxygen limited environments such as the intestine of animals were they may cause severe disease. Among them, the prominent human parasite Giardia intestinalis non-invasively colonizes the small intestine of humans and animals where it induces the gastrointestinal disease giardiasis. READ MORE
