High-chromaticity Optics for the MAX IV 1.5 GeV Storage Ring

The MAX IV facility currently under construction in Lund, Sweden will include a 1.5 GeV storage ring. To prevent head-tail instability, the negative natural chromaticities of the MAX IV 1.5 GeV storage ring have been corrected to positive values using sextupole gradients in the focusing quadrupoles along with dedicated sextupole magnets. To allow adjustment of the chromaticity correction, weak cor

Ströja kyrka – en aristokratisk medeltidskyrka

Today, Brahe Church mainly exhibits signs of the period of greatness of Visingsö island during the seventeenth century. However, there are also traces from much earlier periods. Ströja Church was built during the twelfth century, when the House of Erik and the House of Sverker contested for the title of king and the island of Visingsö had a prominent position in the new country of Sweden. We do no

Impact work-rate and wear of a loosely supported beam subject to harmonic excitation

Impact work-rate of a weakly damped beam with elastic two-sided amplitude constraints subject to harmonic excitation is calculated. Impact work-rate is the rate of energy dissipation to the impacting surfaces. The beam is clamped at one end and constrained by unilateral contact sites near the other end. This system was an object of a vibro-impact experiment which was analyzed in our earlier paper

PCR-based detection of microorganisms in complex biological samples

The detection of microorganisms by PCR can be divided into four steps: (1) sample collection, (2) sample preparation, (3) DNA amplification and (4) detection of PCR products. The major problem in developing PCR-based detection methods is the sample preparation step. This step is necessary to overcome problems caused by PCR inhibitors and it determines, to a large extent, the sensitivity of the PCR

Lighting Recommendations in Operating Theatres

“The eyes lead the body.” A good visual environment is important for performance and wellbeing. Unsatisfactory visual conditions often induce a strained posture, more or less unconsciously, in an effort to improve vision. The requirements for the visual environment in an operating theatre are high. Surgeons or assistants who are having visual problems can induce treatment hazards. The purpose of t

Therapeutic aspects of oral and pharyngeal swallowing dysfunction. Videoradiographic and videomanometric analyses of adult healthy volunteers and dysphagic patients.

Popular Abstract in Swedish Dysfagi är ett symptom på onormal sväljningsförmåga. Detta symptom kan förekomma i samband med många olika sjukdomstillstånd men är vanligast i samband med olika neurologiska sjukdomar t ex stroke. Symptomen kan variera från en lätt känsla av upphakning och svårigheter att svälja specifik föda till livshotande kvävningsanfall. Logopeder har de senaste decennierna tagit In this study simultaneous videoradiography and intraluminal manometry (videomanometry) have been used in combination in three studies to analyze how different therapeutic strategies affect the physiology of swallowing in healthy volunteers and in patients with pharyngeal dysfunction. Analyses of healthy volunteers showed few significant measurable effects on the pharyngeal swallow. Some decreased

Skall äldre särbehandlas?

Allt fler får uppleva sin 100-årsdag. I hela Sverige finns det drygt 2 000 personer som är 100 år eller äldre. På fyrtio år har antalet personer över 65 år ökat med 57 %, från 1,17 miljoner 1972 till 1,83 miljoner 2012 – detta samtidigt som den totala folkmängden bara ökat med 17 %. Vad innebär det att åldras i Sverige? Sverige är ett av de få länder som har en äldreomsorg som omfattar alla oavset

Miljöpraktiker i vardagen: Livsstil, information och förändring i Simrishamn

Miljö och miljöfrågor har under den senaste tiden lyfts fram som ytterst viktiga för framtiden, inte minst växthuseffekten och dess konsekvenser. Att vara och agera miljömedvetet kan sägas ha gått från att ha varit ett val för ett engagerat fåtal till att ha blivit en etablerad livsstil för många. Miljöfrågor är också av stor betydelse för Simrishamns kommun. Under några sommarmånader mer än fördu
