This paper concerns the history of medicine, particularly formal medieval medicine in the Islamic cultural sphere. It focusses on the 9th century physician Qusta ibn Luqa and his production, and includes a survey of the contents of a hitherto unpublished Arabic treatise, attributed to Qusta ibn Luqa, on dental-nerve dysfunction.

The aim of this dissertation is to examine the institutional changes which occurred in Chile under the military regime from 1973-1981, and how these changes can be related to subsequent economic development in the country. The empirical material comprises of an investigation of the new economic policy in the agricultural sector, the political process behind this policy and the social and economic

Popular Abstract in Swedish Avhandlingen behandlar användandet av faltnings koder och Turbo koder för felkorrigering i radio system. Design av koder, avkodare samt metoder för återtransmission behandlas, i syfte att förbättra trafikkapaciteten i digitala radionätverk. Mer specifikt diskuteras design av låg-takts Turbo koder för spritt-spektrum fleranvändarsystem, list sekvens avkodning av länkade New wireless services such as mobile Internet, multimedia streaming and high speed packet data access are making their way to the market. Availability of low-cost equipment providing high transmission quality and efficient spectrum utilization is crucial to the success of these services. This thesis is a collection of papers that address an important step in this direction: efficient error control

In this study, two different methods of estimating cell proliferation were compared: cell loss and potential growth rate of xenografted head and neck cancer grown in nude mice based on the detection of DNA incorporation of bromodeoxyuridine (BrdUrd) in one method, and [3H]thymidine ([3H]TdR) in the other. The 21-d-old xenografts were labelled in vivo, either with BrdUrd or [3H]TdR and excised at i

Photoinduced electron injection from the sensitizer Ru(dcbpy)2(NCS)2 (RuN3) into SnO2 and TiO2 nanocrystalline films occurs by two distinct channels on the femto- and picosecond time scales. The faster electron injection into the conduction band of the different semiconductors originates from the initially excited singlet state of RuN3, and occurs in competition with intersystem crossing. The rate

Extravasated endogenous serum albumin and fibrinogen were identified immunohistochemically in coronal brain sections from normotensive Wistar Kyoto (WKY) rats and spontaneously hypertensive rats (SHR) after permanent ligation of the right middle cerebral artery. Infarcts were seen in all the SHR but only in 6 out of 14 WKY. Six hours after ligation, extravasated proteins were located primarily wit

The charge distribution around the VO bonds in V2O5, V6O13, and V2O4 was calculated by using an empirical formula. The same expression was also used to calculate the oxygen bond strengths on the surface. The surfaces of lower oxides were treated as though they were in an oxidized state which is believed to correspond to the conditions in oxidation and ammoxidation processes. The result is that O2−

AbstractOBJECTIVE. To test the hypothesis that exposure to thermal-degradation products of polyurethane (PUR), particularly isocyanates, induced nasal inflammation.METHODS. Thirty-eight workers -14 with a history of work-related nasal symptoms (WRS/Nose), and 15 referents without such history - exposed to sprayed and heated PUR glue, were studied with regard to biomarkers of isocyanate exposure [4

Popular Abstract in Swedish Användningen av informations och kommunikationsteknik (IKT eller IT) påverkar vårt sätt att kommunicera i arbetslivet. Det underlättar distansarbete och skapar möjligheter till s.k. virtuella möten - att samarbeta utan att träffas fysiskt. Detta kan i sin tur påverka behovet av pendlings- och tjänsteresor, genom att vi får tillgång information, en funktion eller en tjänInformation and Communication Technologies change the way we work and communicate, enabling us to telework and to have virtual meetings - collaborating without a physical meeting. This can influence the need for commuting and business travel by provision of access to an activity without mobility - virtual mobility. The large environmental impact of travel makes this potential travel reduction inte

Popular Abstract in Swedish Den här avhandlingen behandlar analys och bearbetning av bilder ur ett beräkningsmässigt perspektiv. Den är uppdelad i tre delar, vilka diskuterar bilder i så olika sammanhang som i ett artificiellt seende system för robotar, i det mänskliga seendet och i ett bildbehandlingssystem för analys av förbränningsförlopp i tex bilmotorer. Den första delen handlar om två styckThis thesis is divided into three parts, which all deal with computational analysis and processing of images. However, the settings are quite diverse.They range from robotic camera sensors, over human perception, to physical measurement setups. In spite of this diversity, common theoretical ideas and computational aspects are applied which ties the three different parts closer together. The first

Human liver alpha-L-fucosidase (alpha-L-fucoside fucohydrolase, EC 3.2.1.51) has been separated into four components by chromatography on Sephadex G-150 or DEAE-cellulose. These components differ in their relative stability to heat and acid treatment, and their response to neuraminidase. The serum enzyme was devoid of high molecular weight activity and probably contained more sialic acid residues

"En beskrivning av projektet World Music School som syftade till att göra det möjligt för alla barn på grundskolans alla stadier att få möte olika kulturyttringar, vilket kan bidra till ökad omvärldsförståelse, identitet och kulturell samhörighet. Musikhögskolan i Malmö samarbetade med Kulturskolan och tio grundskolor i staden. Projektets uppläggning och genomförande presenteras, diskuteras och u
