Dietary fiber, organic acids and minerals in selected wild edible fruits of Mozambique.

The harvesting, utilization and marketing of indigenous fruits and nuts have been central to the livelihoods of the majority of rural communities in African countries. In this study we report on the content of dietary fiber, minerals and selected organic acids in the pulps and kernels of the wild fruits most commonly consumed in southern Mozambique. The content of soluble fiber in the pulps ranged

Yeast "make-accumulate-consume" life strategy evolved as a multi-step process that predates the whole genome duplication.

When fruits ripen, microbial communities start a fierce competition for the freely available fruit sugars. Three yeast lineages, including baker's yeast Saccharomyces cerevisiae, have independently developed the metabolic activity to convert simple sugars into ethanol even under fully aerobic conditions. This fermentation capacity, named Crabtree effect, reduces the cell-biomass production but pro

Hunden under forntiden : nära kompanjoner i livet och döden

Vi berättar om ett flertal fynd av riktigt gamla hundar från Europa och Asien samt presenterar några av våra svenska exempel. Vi utnyttjar kunskaper från arkeologi och osteologi (läran om skelettet) och tolkar förhållandet mellan hund och människa från allra äldsta stenålder. Vi beskriver också vad som generellt sker med en djurart fysiskt när den tämjs och anpassar sig till ett liv med oss männis

Från Spadarvet till Kokapell: Jordbruk och skogsbruk i konsten

I artikeln görs en översikt över jordbrukets och skogsbrukets närvaro i konsten i Sverige under 1900-talet. Den innehåller också analyser och diskussioner rörande hur, när och varför det agrara motivet är närvarande alternativt frånvarande i konsten under perioden.

Modelling uncertainty for nitrate leaching and nitrous oxide emissions based on a Swedish field experiment with organic crop rotation

High uncertainties are common in detailed quantification of the N budget of agricultural cropping systems. The process-based CoupModel, integrated with the parameter calibration method known as Generalized likelihood uncertainty estimation (GLUE), was used here to define parameter values and estimate an N budget based on experimental data from an organic farming experiment in south-west Sweden. Da

Applicability of Parallel Plate Avalanche Counters to Spontaneous Fission from Cf-252

The construction and performance of the parallel plate avalanche counters (PPACs) using a spontaneous fission source Cf-252 is described in this paper. The parallel plate circular electrodes are made of aluminum foils having a thickness less than ten microns. After fabrication, the detectors and the source are mounted inside a reaction chamber, the source between the two detectors. A low pressure

Coherent Picosecond Exciton Dynamics in a Photosynthetic Reaction Center

Photosynthetic reaction centers convert sunlight into a transmembrane electrochemical potential difference, providing chemical energy to almost all life on earth. Light energy is efficiently transferred through chromophore cofactors to the sites, where charge separation occurs. We applied two-dimensional electronic spectroscopy to assess the role of coherences in the photoresponse of the bacterial

Wild Rodents and Novel Human Pathogen Candidatus Neoehrlichia mikurensis, Southern Sweden.

We examined small mammals as hosts for Anaplasmataceae in southern Sweden. Of 771 rodents, 68 (8.8%) were infected by Candidatus Neoehrlichia mikurensis, but no other Anaplasmataceae were found. Candidatus N. mikurensis has recently been found in human patients in Germany, Switzerland, and Sweden, which suggests that this could be an emerging pathogen in Europe.

Poly(3-hydroxybutyrate) production by Halomonas boliviensis in fed-batch culture.

High poly(3-hydroxybutyrate) (PHB) content and volumetric productivity were achieved by fed-batch culture of Halomonas boliviensis using a defined medium. Initial shake flask cultivations in a minimal medium revealed that the growth of H. boliviensis was supported only when the medium was supplemented with aspartic acid, glycine, or glutamine. Addition of 0.1% (w/v) glutamine in the medium resulte

Bioconversion of industrial hemp to ethanol and methane: The benefits of steam pretreatment and co-production

Several scenarios for ethanol production, methane production (by anaerobic digestion) and co-production of these, using autumn harvested hemp as substrate, were investigated and compared in terms of gross energy output. Steam pretreatment improved the methane production rate compared with mechanical grinding. The methane yield of steam pretreated stems was similar both with and without pre-hydroly

Topics in Machining with Industrial Robot Manipulators and Optimal Motion Control

Two main topics are considered in this thesis: Machining with industrial robot manipulators and optimal motion control of robots and vehicles. The motivation for research on the first subject is the need for flexible and accurate production processes employing industrial robots as their main component. The challenge to overcome here is to achieve high-accuracy machining solutions, in spite of the

A 5GHz 90-nm CMOS all digital phase-locked loop

An all digital phase-locked loop (ADPLL) has been implemented in a 90-nm CMOS process. It uses a phase-frequency detector (PFD) connected to two time-to-digital converters (TDC). To save power the TDCs use delay line cells with uneven delay time. During frequency acquisition an automatic tuning bank controller selects active bank of the digitally controlled oscillator (DCO), which features three s

Variability of important vital rates challenges the demographic buffering hypothesis

Selection is assumed to eliminate life-histories showing high variability in vital rates that have the greatest influence on population performance. Therefore, an inverse variability-importance relationship of vital rates is believed to be a universal pattern for diverse life-histories. We tested for such a relationship using multi-year demographic data on a large number of populations of two pere

Christian Manliness For Women? Contradictions of Christian youth organization in early 20th-century Sweden

Evangelical revivalism attracted large numbers of young adherents in early 20th-century Sweden. In this article we discuss what happened when Christian youth societies for men and women merged into mixed societies. The decline of the ideal of the single-sex youth society meant that a decidedly female form of religious organization disappeared. We argue, however, that the change also entailed cauti
