Pancreatic islets have a central role in blood glucose homeostasis. In addition to insulin-producing beta-cells and glucagon-secreting alpha-cells, the islets contain somatostatin-releasing delta-cells(1). Somatostatin is a powerful inhibitor of insulin and glucagon secretion(2). It is normally secreted in response to glucose(3) and there is evidence suggesting its release becomes perturbed in dia

The thesis concerns risk and safety in manufacturing companies in a developing country. Risk and safety is viewed as integral to the social relations between management and labour. The Malaysian case presents a historical conjuncture of this conflict theme, which is very different from that of its Western genesis. On this basis, the primary objective of the thesis is defined as an effort to escape

The resonance lines of helium in the Sun are several times stronger than expected, relative to lines of other ions. To explore the origins of this "helium enhancement,'' we have studied data from the SUMER, CDS, MDI, and EIT instruments on the Solar and Heliospheric Observatory (SOHO). Time series data obtained in a quiet region and a coronal hole indicate that the spatio-temporal properties of th

Popular Abstract in Swedish Gastroesofageal refluxsjukdom innebär att maginnehåll backar (reflux) upp från magsäcken till matstrupen på ett onormalt sätt. Hos den friska individen finns flera mekanismer som skyddar matstrupen från reflux, vilket tydligt åskådliggörs av att man efter en måltid kan ställa sig upp och ner utan att föda backar upp i matstrupen. Vid refluxsjukdom föreligger defekter inEsophageal pH monitoring is important in the clinical management of patients with symptoms suggestive of gastroesophageal reflux disease (GERD), and in research aiming to clarify the mechanisms involved in the development of GERD complications. Catheter-based techniques for pH recording are uncomfortable, not well tolerated by all patients and cannot reliably measure acid exposure in the most dist

This thesis investigates a set of degree modifiers of adjectives common in spoken British English. The main focus of the study is on generalizable semantic and intonational features, but attention is also given to the use of the modifiers in authentic speech in terms of frequency, collocability and intonation. The study explores the semantic constraints that govern the relationship between degree

BACKGROUND: Thrombosis is one of the most important causes of morbidity in the medical field. Several independent in vitro studies have shown that the fibrinolytic process may be enhanced by ultrasound, but the effect of ultrasound on thrombus formation in vivo is unexplored. The present study was designed to investigate this matter. METHODS: In a blind randomized study, standardized arteriotomies

Artikeln belyser exilens tematik i texter av Paul Celan, Emmanuel Levinas och Zvi Kolitz.

Muslimer framställs idag som sexualfientliga puritaner, medan de inom orientalismen sågs som lustfyllda med en bestialisk, okontrollerad sexualitet i sina harem. Muslimer har konstruerats som ”den andra” i relation till väst, men vad vet vi egentligen om muslimsk sexualitet? I artikeln hävdas att muslimer traditionellt har haft en öppnare inställning till sexualitet än den strikta sexualmoral som

In this work the problem of designing feedback controllers for the rejection of narrow-band disturbances is considered. The design technique proposed herein is based upon a well-suited overparameterization of a standard model-based minimum-variance controller; the extra-degrees-of-freedom so introduced are used to improve the performence of the basic controller. In particular, the problem of impro
