A two-step, un-coupled process producing hydrogen (H2) from wheat straw using Caldicellulosiruptor saccharolyticus in a ‘Continuously stirred tank reactor’ (CSTR) followed by anaerobic digestion of its effluent to produce methane (CH4) was investigated. C. saccharolyticus was able to convert wheat straw hydrolysate to hydrogen at maximum production rate of approximately 5.2 L H2/L/Day. The organic

The Swedish pulp and paper industry accounts for half of industrial final energy use in Sweden and 2.3 % in EU-27. On the basis of a disaggregated set of physical production data, a Logarithmic Mean Divisia Index decomposition method is applied to disentangle the influence from activity, structure and energy efficiency improvement (EEI) on its fuel, electricity and primary energy use. An extended

The development of human pluripotent stem cells has opened up the possibility to analyse the function of human cells and tissues in animal hosts, thus generating chimeras. Although such lines of research have great potential for both basic and translational science, they also raise unique ethical issues that must be considered.

Limonene, one of the most often used fragrance terpenes in any kind of scented products, is prone to air-oxidation. The oxidation products formed have a considerable sensitizing potential. In previous patch test studies on consecutively tested dermatitis patients, oxidized R-limonene has been proven to be a good and frequent indicator of fragrance-related contact allergy. The current study extends

Aim: To analyse morbidity and mortality in healthy newborn infants in relation to various routines of post-natal follow-up. Design: cross-sectional study. Setting: maternity care in Sweden. Population: healthy infants born at term between 1999 and 2002 (n = 197 898). Methods: Assessment of post-natal follow-up routines after uncomplicated childbirth in 48 hospitals and data collected from the Swed

Massive MIMO can greatly increase both spectral and transmit-energy efficiency. This is achieved by allowing the number of antennas and RF chains to grow very large. However, the challenges include high system complexity and hardware energy consumption. Here we investigate the possibilities to reduce the required number of RF chains, by performing antenna selection. While this approach is not a ve

Aims: Objectives were (a) to estimate healthcare cost and productivity losses due to smoking in Sweden 2001 and (b) to compare the results with studies for Sweden 1980, Canada 1991, Germany 1996, and the USA 1998. Methods: Published estimates on relative risks and Swedish smoking patterns were used to calculate attributable risks for smokers and former smokers. These were applied to cost estimates

High spin states in the nucleus Tc-90 have been identified for the first time via the fusion evaporation reaction (Ni(Ar,3pn)Tc)-Ni-58-Ar-36-Tc-90, at 149 MeV beam energy. The OSIRIS spectrometer with an additional high purity Ge detector at 162-degrees and several particle detectors were used to measure gammagamma and particle-gammagamma coincidences, directional correlations of oriented states (

Aim: To explore whether the phrasing of the questions and the response alternatives would influence the answers to questions about legalisation of euthanasia. Methods: Results were compared from two different surveys in populations with similar characteristics. The alternatives "positive'', "negative'', and "don't know'' (first questionnaire) were replaced with an explanatory text, "no legal sanct

Jalil Haidar (född i Baghdad 1945, är sedan 1991 bosatt i Malmö)arbetar med ett sparsmakat språk befriat från äldre tiders retorik. Hans texter är täta och intensiva under en skenbar enkelhet. Bakom diktningen ligger ett engagemang i mänsklighetens och poesins vilkor, en strävan efter människans frihet och en bättre framtid.
