The new injector for MAX-lab is built around two 125 MeV linacs [B. Anderberg, (2000)] equipped with SLED cavities [Z.D. Farkas, (1974)]. The electron beam is recirculated once to reach 500 MeV. A 2.3 MeV thermionic RF gun [B. Anderberg, (2000)] injects into the system. The RF-gun is put into operation and commissioning of the first linac is proceeding. Results from the thermionic RF-gun operation

In recent decades, lifestyles have changed worldwide and the transition into an increasingly sedentary lifestyles is a major health concern, the origins whi
Popular Abstract in Swedish GENETISK VARIATION OCH SEXUELL REPRODUKTION I EN MOSSA MED DVÄRGHANNAR, KALKLOCKMOSSA Mycket små hannar (dvs. dvärghannar) finns i flera olika djurgrupper men inom landväxterna bara hos mossor. Hos mossor uppstår dvärghannarna ifrån hansporer som landar och gror på honskottet där de inte blir större än några millimeter. Sporerna bildas inuti sporkapseln, som växer ut ifDwarf males occur in many unrelated groups of organisms. Among land plants they are unique to mosses. Moss dwarf males originate from male spores that land and germinate on the female where their final size is restricted to a few mm. Fertilization in mosses occur over short distances with swimming spermatozoids. Having the males growing as tiny epiphytes on the females facilitates fertilization, a
Breast reconstruction is an everyday, apparently non-violent, even benevolent, remaking of the normal and the reasons for why reconstruction is motivated and legitimate are uncontroversial and widely accepted. In this article I will, through Donna Haraway’s way of conceptualizing discourses, analyze what I call “stories without significance”. I have mapped the stories and interpretations women und
Popular Abstract in Swedish Svängningar i antalet individer hos en organismgrupp har under lång tid intresserat forskningen. Men sådana fluktuationer i populationer har inte bara ett vetenskapligt intresse. En ökad förståelse för fenomen som dessa kan hjälpa oss att fatta bättre beslut rörande mänskliga aktiviteter såsom fiske, jakt, skogsbruk och jordbruk och förhoppningsvis leda oss mot ett mer We are interested in the effect of harvesting on population fluctuations and for that purpose we develop and analyze an age-structured model where recruitment is a stochastic process and the adult segment of the population is harvested. When a constant annual harvest is taken the coefficient of variation of the adult population increases for most parameter values due to the age truncation effect,
Popular Abstract in Swedish Den eosinofila granulocyten är en typ av vit blodkropp som ingår i kroppens immunförsvar. Vid allergirelaterade sjukdomar ses en ökad mängd av eosinofiler i blodbanan samt lokalt i den allergiskt inflammerade vävnaden. I vävnaden släpper eosinofilerna ut sina granulaproteiner som har celldödande, immunförsvarsreglerande och tillväxtfrämjande egenskaper. Hos patienter meIn allergic disorders, the eosinophilic granulocytes migrate to affected tissues and release granule proteins with cytotoxic, immunoregulatory, and remodeling-promoting properties. Given that degranulation is reflected by a loss in eosinophil granule density of living cells, or by cell membrane rupture and release of intact granules, these morphological changes may represent a biomarker of the all
Popular Abstract in Swedish Proteiner är biologiska molekyler som kan utvinnas ur olika bakterier, svampar, djur och människor. I sin naturliga miljö bidrar de bl. a. till att katalysera (snabba på) olika kemiska reaktioner (enzymer), att sköta transporten av olika molekyler, bidra till immunförsvaret och tillväxtkontroll (hormoner). Upptäckten att proteiners olika funktion kan uttnyttjas i många The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. NMR spectroscopy revealed changes in the relaxation properties of Ala and Thr methyl groups in lysozyme, indicating compression of the enzyme as a consequence of pr
