We trace the difference between the ways in which apes and humans co–operate to differences in communicative abilities, claiming that the pressure for future–directed co–operation was a major force behind the evolution of language. Competitive co–operation concerns goals that are present in the environment and have stable values. It relies on either signalling or joint attention. Future–directed c

To study whether antibodies to glutamic acid decarboxylase (GADab) are associated with subclinical beta-cell damage and impaired insulin secretion, we screened 441 nondiabetic patients with autoimmune thyroiditis (AT) for GADab, and 15 (3.4%) were found positive. Antibodies to IA-2 were found in two GADab+ and one GADab- patients. We matched 11 GADab+ and 13 GADab- AT patients who were euthyroid o

Box jellyfish, or cubomedusae, possess an impressive total of 24 eyes of four morphologically different types. Compared to other cnidarians they also have an elaborate behavioral repertoire, which for a large part seems to be visually guided. Two of the four types of cubomedusean eyes, called the upper and the lower lens eye, are camera type eyes with spherical fish-like lenses. Here we explore th

Thidevalls avhandling i kyrkohistoria utgår från Svenska kyrkans möte med det moderna samhället. Hypotesen är att Svenska kyrkan fick sina strukturer präglade av andra intressen än biskopsmotionens reformprogram 1929. Detta program sätts in i sin kyrkopolitiska närkontext med nya kommunallagar, församlingsstyrelselag, Kungl. Maj:ts beslut att ge Lilla katekesen större utrymme i folkskolan, och öve

Time-resolved laser-induced fluorescence measurements have been performed for ten odd Rydberg states of neutral lutetium, belonging to the 6s(2)(S-1)np(n = 8-9) and 6 s(2)(S-1)nf (n = 5-8) series. For 6S(2)(S-1)8p and 6s(2)(S-1)7f, the experimental lifetimes corresponding to the two J values within the doublet differ substantially. Comparison with theoretical values, calculated with extensive conf

Popular Abstract in Swedish I denna avhandling har jag undersökt hur man kan utöka det dynamiska omfånget utan att öka noggrannheten i en analog-till-digital omvandlare med en flyttalsliknande lösning. Den valda lösningen går ut på att man förstärker en analog insignal med flera oberoende analoga förstärkare med skilda förstärkningar. Sedan väljs den förstärkare som ger den starkaste utsignalen sTo deal with the wide dynamic rage necessary for a radio receiver or corresponding applications, but to avoid impractically high resolution at high data rates, the approach of using a floating-point analog-to-digital converter (FP-ADC) has been investigated. This approach de-links the dynamic range with the resolution, and a very wide dynamic range can be achieved by an ADC with a moderate resolut

Are you interested in or curious about Batch Control, ISA S88, and/or Plant Automation in general, then this whitepaper is for you. In the following three pages you will learn the basics about Batch Control and ISA S88 and you will understand how you can benefit from knowing them. For a deeper understanding I recommend you to read the other whitepapers in this series as well as reading the ISA S8

During the spring of 2003 ninety-five water bodies in southeastern Estonia were surveyed for chrysophytes. The sampling was carried out as the ice broke up, when, within two weeks, the water temperature rose from 3 degrees C to 13 degrees C. Large lakes to small pools of different water chemistry were investigated. The plankton collected was studied alive within a few hours after sampling. Prepara

The Department of English in Lund: Working Papers in Linguistics is an annual volume produced by the English Department at Lund University in Sweden. Its main aim is to publicize research being carried out by staff and post-graduate students in the department, but we are also pleased to include contributions from members of neighbouring departments and universities. The contributions in volume 3

Electrostatic effects often dominate the behavior of charged surfactant systems. While descriptions on the level of the Poisson-Boltzmann equation are successful in describing many important features of such systems, they cannot predict those specific ion effects arising when changing counterions of the same valency and they often fail in predicting effects due to changing from a monovalent to a d

Hexahydrophthalic anhydride (HHPA; CAS No. 13149-00-3) is a highly allergenic compound commonly used in the chemical industry. Guinea pigs and rats were exposed to [3H2]HHPA by inhalation for 3-8 h and were killed at various intervals during 7 days. The tissue distribution of non-volatile and covalently bound radioactivity was studied by autoradiography. Tissue bound radioactivity was mainly found

The report describes three investigations of emissions from alkali attack on adhesives and floorings. The investigations show that low alkali levelling compounds, based on calcium aluminate cement, can act as a protection against secondary emissions of 1-butanol and 2-ethylhexanol, provided that the humidity does not exceed a critical level, which with some safety margin is recommended to be 90% R

The development of real-time PCR thermal cycles in the late 1990s has opened up the possibility of accurate quantification of microorganisms in clinical, environmental, and food samples. However, a lack of suitable sample preparation methods that allow rapid quantification of the nucleic acids, remove PCR inhibitors, and prevent false-positive results due to DNA originating from dead cells has lim

The influence of the shear on the lamellar phase, L, of the system C10E3/D2O was studied along an isoplethal path (40 wt.% C10E3) in the temperature range 25-42degreesC. A dynamic phase diagram was determined by steady-state rheometry, where by shear action the lamellar phase was transformed into multilamellar vesicles (MLVs) ("onions"). The location of "onions" in the dynamic phase diagram, depen
