An economy consisting of n>=2 different types of consumers and one publicly owned natural monopoly is under consideration. The preferences of the consumers are assumed to be linear in money and the demand curves are assumed not to cross. We also suppose that the net utility from consumption is so high that we do not have to consider the individual rationality constraints. Given these assumptions,

Popular Abstract in Swedish De fyra studier som ingår i denna avhandling är gjorda för att undersöka eventuella oönskade effekter av läkemedel på näthinnan. Näthinnan är en del av det centrala nervsystemet och känslig för toxiska substanser. För att skydda näthinnan så finns två barriärer – en yttre och en inre blod–näthinne- barriär. Dessa barriärer består av strukturer som håller samman celler i

We have studied the early stages of GaInP overgrowth on InP quantum dots (QD's) experimentally and theoretically. A direct correlation between the surface morphology and the optical properties of individual InP QD's is made using scanning tunneling microscopy (STM) and scanning tunneling luminescence. The geometric structure of the islands is further investigated using cross-sectional transmission

THE search for 242mAm (t1/2=152 yr) in environmental samples has involved detection of its daughter 242Cm (t 1/2=163 d) (refs 1-3). These samples were contaminated by transuranium nuclides either from a nuclear fuel reprocessing plant or from a thermonuclear test fallout. A logical consequence was then to analyse global fallout-contaminated samples for 242Cm and 244Cm to establish the present dist

The present paper shows that cross‐section demeaning with respect to time fixed effects is more useful than commonly appreciated, in that it enables consistent and asymptotically normal estimation of interactive effects models with heterogeneous slope coefficients when the number of time periods, T , is small and only the number of cross‐sectional units, N , is large. This is important when using

Context. Reconstructing the Galactic evolution of lithium (Li) is the main tool used to constrain the source(s) of Li enrichment in the Galaxy. Recent results have suggested a decline in Li at supersolar metallicities, which may indicate reduced production. Aims. We exploit the unique characteristics of the Gaia-ESO Survey open star cluster sample to further investigate this issue and to better co

Phosphor thermometry is a temperature measurement technique that has previously been employed in technically relevant applications to obtain surface temperature. The technique is based on temperature-dependent changes in a phosphor's luminescence. To improve the accuracy and precision of temperature measurements with this technique, the present study considers, by way of example, the impact of con

Context. The extensive stellar spectroscopic datasets that are available for studies in Galactic Archeaology thanks to, for example, the Gaia-ESO Survey, now benefit from having a significant number of targets that overlap with asteroseismology projects such as Kepler, K2, and CoRoT. Combining the measurements from spectroscopy and asteroseismology allows us to attain greater accuracy with regard

Beginning in December 2010, the Arab world was hit by huge anti-government revolutionary waves, popularly known as the Arab Spring. In Syria, the uprising did not take long to morph into a bloody war with international and regional powers wrestling for geopolitical influence and economic gain. The war has significantly changed Syria in terms of politics, economy, and culture. While the first two h

Innate lymphoid cells (ILC) represent a group of lymphocytes that lack specific antigen receptors and are relatively rare as compared to adaptive lymphocytes. ILCs play important roles in allergic and nonallergic inflammatory diseases due to their location at barrier surfaces within the airways, gut, and skin, and they respond to cytokines produced by activated cells in their local environment. In

This paper presents a study of the role that photography of 14 October 1973 and 6 October 1976 has played in political mobilization around the two events. It is well known that in official archives limited versions of the events can be found. We must turn to alternative repositories (private homes, non­states organisations, but also universities and libraries outside of Thailand) to find the antic

Many industries have benefited from modularisation; while in the architecture, engineering and construction (AEC) industry, the concept of modularisation is associated with dimensional coordination. This has added to an already extensive list of challenges due to market size and the concept of economies of scale in AEC industry, to name but a few. Moreover, there is a myth that the AEC industry is
