A series of intramolecular condensation products were obtained by base-catalyzed treatment of the natural bioactive dimeric phthalide diligustilide (1) using different reaction conditions and the yields remarkably depend on these. The reaction conditions to obtain selectively the intramolecular condensation derivatives or the hydrolysis products of diligustilide (1) are described.

A method for simultaneous determination of 5-hydroxy-N-methyl-2-pyrrolidone (5-HNMP) and 2-hydroxy-N-methylsuccinimide (2-HMSI) was developed. These compounds are metabolites from N-methyl-2-pyrrolidone (NMP), a powerful and widely used organic solvent. 5-HNMP and 2-HMSI were purified from plasma and urine by solid-phase extraction using Isolute ENV+ columns, and analysed by liquid chromatography

Inom en snar framtid kommer många havsbaserade vindkraftverk troligen att byggas runt om Sveriges kuster. Det bör finnas ett behov av gemensamma regler eller tekniska lösningar inför en sådan byggnation så att vindkraftverken som helhet får en avsedd livslängd och små underhållskostnader.

Popular Abstract in Swedish SAMMANFATTNING PÅ SVENSKA (Swedish summary) Ultraljud används sedan 1970-talet rutinmässigt under graviditet. Undersökningen görs vanligen vid 17-18 graviditetsveckor och syftet med undersökningen är att datera graviditeten dvs bestämma tiden för beräknad förlossning. Man upptäcker också eventuella tvillingar vid denna undersökning. Redan tidigt visade det sig att visWe studied the prenatal detection rate of various malformations during a study period of 16 years in a population in southern Sweden consisting of 141 240 deliveries. The overall detection rate was 28.4% and the false positive diagnoses were very few. We studied the effect of prenatal diagnosis on the rate of spina bifida in southern Sweden compared with the rest of the country and could show tha

Determination of D-arabinitol/L-arabinitol ratios (referred to as D/L-arabinitol ratios) in urine as a tool for the diagnosis of invasive candidiasis was investigated in a prospective study comprising 100 children with cancer. The analyses were made by gas chromatography. Positive D/L-arabinitol ratios were found for 10 of 10 children with confirmed invasive candidiasis, 12 of 23 patients undergoi

Abstract in French Description. Afin d'orienter les recherches futures dans les domaines des aides techniques et des questions liées à l'environnement physique, il est important de bien comprendre les études menées précédemment. But. Cette recension des écrits avait pour but de déterminer la manière selon laquelle les aides techniques et les questions touchant l'environnement physique ont été étudBackground. To determine future directions for research in the area of assistive technology and physical environmental issues, it is important to have an understanding of prior research. Purpose. This literature review examined how assistive technology and physical environmental issues have been studied in the research published in international peer-reviewed occupational therapy journals. Method.

This Article Discusses the Wrong Beliefs of Some Yemenis, that they think where there are some safe areas that mean there is a state, meanwhile, these areas under control of the militias and other armed groups.

A separation between the academic subjects statistics and mathematical statistics has existed in Sweden almost as long as there have been statistics professors. The same distinction has not been maintained in other countries. Why has it been kept for so long in Sweden, and what consequences may it have had?In May 2015, it was 100 years since Mathematical Statistics was formally established as an aA separation between the academic subjects statistics and mathematical statistics has existed in Sweden almost as long as there have been statistics professors.
