A model is presented which gives a quantitative picture of the distribution of the photosynthetic components in the thylakoid membrane of higher plants. The model is based on fragmentation and separation analysis together with microscopy. A salient feature of the model is that over 80 per cent of the pigments are located in the grana where the two photosystems 1 and 2 produce oxygen, NADPH and ATP

Story-telling is increasingly accepted as a management strategy aiming to build commitment to, and acceptance for, ideas, brands and organizations. But what happens when story-telling meets transparency demands in public sector reform? This topic is explored in this paper. It builds on a case study of a major public sector reform, including the merger of two hospitals in the south of Sweden. The s

Popular Abstract in Swedish Total parenteral nutrition (TPN) används för näringstillförsel till patienter som av olika orsaker inte kan försörja sig via sedvanligt födointag. Vid TPN tillföres fett, socker, aminosyror (proteinernas byggstenar), vitaminer och salter i mängder tillräckligt för att täcka det dagliga behovet. Näringsämnena tillföres via en blodåder och passerar således inte magtarmkanDuring total parenteral nutrition (TPN) adequate nutrition is provided intravenously and the enteral route is bypassed. The integrity of the gastrointestinal (GI) tract, however, is dependent on the passage of food through it. This thesis deals with the effects of TPN on the pancreas and the parotid glands. TPN induced hypotrophy of the exocrine pancreas and the parotid glands. The amylase concent

En del saker berör människor till den grad att gängse normer och idéer ställs på huvudet. Synen på kroppen och hälsan är ett sådant fenomen. Längtan efter en speciell slags kropp är en historiskt välkänd drivkraft med konsekvenser för hur samtiden utformas. Den moderna biovetenskapen utgör i det sammanhanget en betydelsefull arena för mötet mellan människors drömmar och samhällets riktlinjer. Här

The experimental knowledge of the Cu-61(29)32 and Zn-61(30)31 nuclei has been largely extended via the joint results from three experiments. The fusion-evaporation reaction used a Ar-36 beam and a Si-28 target foil to produce the two nuclei via the evaporation of either three protons (Cu-61) or two protons and a neutron (Zn-61). The experimental set-ups comprised the Ge-array GAMMASPHERE as well a

Popular Abstract in Swedish Vid vattenabsorption i en polymer antas vattenmolekylerna röra sig genom polymeren via små kaviteter, som inte upptas av polymermolekylerna och dess termiska vibrationer. Den ej upptagna volymen, som de små kaviteterna representerar kallas fri volym. Storleken på kaviteterna liksom andra egenskaper hos polymeren såsom andelen kristallin fas ändras kontinuerligt i takt mDuring moisture uptake in polymers, the diffusion of the water molecules is believed to occur via unoccupied voids. These voids are called free volume cavities and their sizes are continuously altered when the moisture content in the polymer is enhanced. Not only the free volume cavity sizes, but also other polymer properties such as the degree of crystallinity, are changed as a consequence of moi

During the last years work has been carried out in collaboration between Lund University, WSP Acoustics and the Royal Institute of Technology (KTH) in Stockholm, to bring more basis for impact sound evaluation in the field situation. Results from this study so far, indicate that current international (ISO 717) method is unsatisfactory, and improvements are probably necessary. In this paper we disc

In this study, the adsorption of nonionic amphiphiles from aqueous solutions to solid, planar surfaces is investigated using null ellipsometry. This technique allows independent measurements of the amounts adsorbed at the surface and of the mean optical thickness of the adsorbed layer. The time resolution is sufficient for investigating the dynamics of adsorption and desorption in systems of this
