Popular Abstract in Swedish Många har fascinerats av det mystiska Mayafolket som byggde fantastiska städer med tempelpyramider, astronomiska observatorier och bollplaner djupt inne i djungeln i Guatemala och Mexiko. Vilka var de som utvecklade denna högkultur med hieroglyfer och avancerade kalendrar? Denna avhandling presenterar Mayaindianernas religion och historia. Frågor som söker sina svar är This thesis deals with Maya religion and history. The Books of Chilam Balam is the collective title of a body of texts ascribed to the Jaguar Prophet. They are written in the Yucatec Maya language, and tell the reader about Yucatec Maya cosmology, rituals, prophecies, calendars, medicine and they are as well considered as Yucatec Maya emic historiography. These manuscripts are considered enigmatic

The effect of intraileally infused short chain fatty acids (SCFA) and saline as control on the exocrine pancreatic secretions during the interdigestive phase was studied using three 8-weeks-old piglets. Pigs were surgically fitted with a pancreatic duct catheter, re-entrant duodenal T-cannula for collection and subsequent return of pancreatic juice, and with an infusion T-cannula at the distal ile

To investigate subjective and objective changes in function in subjects with Parkinson's disease (PD) home visits with interviews were performed with a 1-year interval. Depressive symptoms were rated with the Geriatric Depression Scale, subjective health with the generic SF-36 scale and the disease-specific PDQ-8 scale; objective changes were assessed according to the Hoehn and Yahr scale; insomni

The sensitivity of the rat submaxillary gland was examined 3-4 weeks after either parasympathetic decentralization or sympathetic decentralization or denervation. The threshold doses for secretion of saliva of parasympathomimetic (methacholine) and sympathomimetic (noradrenaline, adrenaline, phenylephrine and isoprenaline) drugs were estimated and the amount of saliva secreted in response to supra

Over the last three and half decades Sweden have provided development aid to Ethiopia. This aid was used to expand Ethiopia's educutional system, public health service and agricultural production. This empiricaI study reveals Ethiopia's response to Swedish aid and its influence. Providing and receiving aid explains the existence of disparity among sovereign states. In spite of the demonstrative i

Popular Abstract in Swedish Under 1990-talet har från olika håll ställts krav på ett ökat elevinflytande över innehåll och arbetsformer i den allmänna skolan. Dessa krav har dels kommit från eleverna själva, dels kommit till uttryck i olika styrdokument. Att så har varit fallet ter sig ganska naturligt, eftersom den tidsanda i vilken vi lever är präglad av individualism. Ett antagande, som stöds aAbstract In the Swedish compulsory school system there is a trend towards increased student influence. School ideologists have for at least ten years strongly emphasised this issue. This tendency is in line with a more general direction in Western societies, which in many aspects has moved toward individualisation. Based on these developments, the main reason for undertaking the presents study was

This study examined the neurophysiological effects of cannabis. Cerebral blood flow (CBF) was measured in 12 long-term cannabis users shortly after cessation of cannabis use (mean 1.6 days). The findings showed significantly lower mean hemispheric blood flow values and significantly lower frontal values in the cannabis subjects compared to normal controls. The results suggest that the functional l

The aim of this study was to evaluate the synthetic C6 peptide test as a first-line test in a two-tiered scheme for Borrelia serology in a clinically well-characterized population of patients with Lyme borreliosis in Kalmar County, Sweden. The study population consisted of a prospective group (n=200), a control group (n=255), and a retrospective group (n=29). The test panel consisted of the Immune

With the attempts to achieve higher thermal efficiency, turbine blades are exposed to very high temperature gases and may undergo severe thermal stress and fatigue. Thus, in order to develop optimal cooling strategies and reduce the heat transfer it is important to obtain a good understanding of both the complex flow field and the heat transfer characteristics in turbine rotor/stator hot-gas passa

I denna rapport redovisas dels en övergripande bild över arbetstidsförkortningsdebatten och dels tre försöksprojekt med arbetstidsförkortning som bedrevs under ett och ett halvt år i Malmö kommun. Det hävdas att debatten har utvecklats till en kontrovers i vilken olika grupperingar av debattaktörer kan urskiljas utifrån sina ställningstaganden till reformen, och att det kunskapsunderlag som finns

The photodissociation of bromobenzene in solution was investigated with ultrafast transient absorption spectroscopy following excitation at 266 nm. Ab initio calculations of lower singlet and triplet states were performed in order to guide the interpretations. The main feature of the kinetics measured between 300 and 930 nm in acetonitrile is a 9±1 ps decay, which we mainly assign to predissociati

In order to demonstrate the feasibility of the proton microprobe in the analysis of dermatological material when a spatial resolution of a few micrometres is sufficient and to compare it with the electron microprobe technique, duplicate sections of human skin have been analysed with both methods. A skin sample was obtained from each of three healthy volunteers. After cryosectioning (12 μm) and fre

New radiative lifetimes for 20 levels of Pr II have been measured using the time-resolved laser-induced fluorescence (LIF) technique. The combination of these experimental values with theoretical branching fractions (BF) obtained with the pseudo-relativistic Hartree-Fock (HFR) approach has allowed us to determine oscillator strengths and transition probabilities for about 150 lines appearing in th
