A strain of an alkaliphilic bacterium Bacillus halodurans was isolated from a water sample in Lake Shalla, a soda lake in the Ethiopian Rift Valley. From the culture of this isolate, B. halodurans S7, a xylanase which is active in a wide range of pH, with an optimum at about 9-9.5 was purified. When assayed at pH 10, the enzyme was optimally active at 70 ?C. The xylanase was free from any associat
Popular Abstract in Swedish Membranproteiner är tämligen svåra att digerera med enzym som trypsin. Mindre specifika enzym såsom elastase och pepsin har dock visat sig mer effektiva. Databassökningar med dessa icke-tryptiska peptider är mindre verkningsfulla pga avsaknaden av laddning vid peptidens N-terminal och C-terminal samt brist på sekvensspecificitet. Vi beskriver en metod med specifik N-teMembrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. We describe a method for N-terminal specific labelling of peptides fr
A previous article by the author demonstrated that the supplier of corrugated board in the relationship studied cannot be considered a strategic supplier. Despite this, the manufacturing company has chosen to go through with the efforts of supplier integration with the supplier of corrugated board. This indicates a difference in the driving forces and the future nature of the relationship between
I denna antologi om Peter Wieselgren (1800-1877) medverkar elva författare med olika aspekter: historikern, nykterhetsmannen, brevskrivaren, publicisten osv. Mitt bidrag om den kyrkliga gärningen fokuserar på väckelsens budskap i romantikens gestalt som Wieselgrens utgångspunkt. Under rubriken "Aktör på många arenor" behandlas Wieselgrens mångsyssleri, och till sist får hans biblicistiska motiveri
The paper presents design considerations for a digital Cellular Neural Network. The architectural spectrum is categorized from a rich variety in nodal structural transformations and formulated by an exploration model. This model is then applied to study the influence of the memory band-gap. Experiments show the benefits of a tiled implementation, mixing spatial network parallelism with time-multip
Människan är biologiskt förberedd för social interaktion och vi formas i hög grad av de speciella sociala erfarenheter vi gör och den kultur som vi är omgivna av. Vi är styrda av biologiskt nedlagda affekter, affekter som i samverkan med ett annat biologiskt nedlagt system, anknytningssystemet, inriktar oss mot att söka nära, trygga relationer. I det sociala samspelet påverkas vi intuitivt av andr
Background Positivism is sometimes rejected for the wrong reasons. Influential textbooks on nursing research and in other disciplines tend to reinforce the misconceptions underlying these rejections. This is problematic, since it provides students of these disciplines with a poor basis for making epistemological and methodological decisions. It is particularly common for positivist views on realit
In their introductory chapter to the anthology "MEDIER & POLITK: Om arbetarrörelsens mediestrategier under 1900-talet", the two editors present a brief history of the ways in which the Swedish Labor Movement has used and related to various media during the last hundred years.
