Around 1800 and thereafter there was a rising consumption of books and other print material in Sweden. Almanacs, handbooks and fiction, especially for women, children’s books, ABC- and conversation cards and other prints such as, games, pictures for cutting and music was advertised in newspapers and booksellers catalogues. In this text the production and commercialisation of these products is look
Typically a donor-acceptor (D-A) design strategy is used for engineering the bandgap of polymers for solar cells. However, in this work, a series of alternating D-A(1-)D-A(2) copolymers PnTQTI(F) were synthesized and characterized with oligothiophenes (nT, n = 1, 2, 3) as the donor and two electron-deficient moieties, quinoxaline and isoindigo, as the acceptors in the repeating unit. We have studi
Popular Abstract in Swedish Mycken möda har under de senaste årtiondena lagts ner på forskning om försurande utsläpp och dess skadliga effekter på skogar, vattendrag och människor. Kritiska belastningsgränser, i folkmun kallat "vad naturen tål", har tagits fram och använts i europeiska förhandlingar om utsläppbegränsningar. För skogsekosystem baseras de kritiska belastningsgränserna för försurandeAcidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.g. for Swede
In this time-course study the levels of different reactive species, especially those of nitric oxide and peroxynitrite were determined in streptozotocin-induced diabetic rat tissues at different time-points after the onset of the disease, before the development of histopathological damages. Significantly higher steady state free radical concentrations were found in the liver 3 weeks after the onse
Defect reactions associated with the elimination of divacancies (V-2) have been studied in n-type Czochralski (Cz) grown and float-zone (FZ) grown Si crystals by means of conventional deep-level transient spectroscopy and high-resolution Laplace deep-level transient spectroscopy (LDLTS). Divacancies were introduced into the crystals by irradiation with 4 MeV electrons. Temperature ranges of the di
Early diagnosis of atherosclerosis is essential as many of the risk factors are life-style dependent. We suggest a new method to measure minute roughness of the size of micrometers of the arterial wall. The method was evaluated using three silicone phantoms sized 13 fun, 23 itm and 33 pm, respectively. The mean of the measured heights of the phantoms were 8.1 mu m (SD 0.0), 23.3 mu m (SD 0.2) and
Background: The coexistence of cataract and age related macular degeneration (AMD) is not unusual, especially in the very elderly. The outcome of cataract surgery in these cases depends on the effect of AMD on vision. In this study the authors have compared the outcome of cataract patients with AMD to that of cataract patients with no vision threatening ocular comorbidity, and analysed possible pr
A number of reports have been examined of tests undertaken by FRS and by FIRTO for the purpose of studying the behaviour of sprinkler systems in controlling fires in piles of stacked cardboard cartons. Mean speeds of the rising flame tip have been estimated and found to be very variable. Typically if ignition is on the vertical outside "face" speeds are 1-3 cm/sec. Ignition in a "face" is typicall
A mu-ISLM (micro Immuno Supported Liquid Membrane) extraction system coupled in a sequential injection analysis (SIA) configuration, capable of simultaneous sample cleanup and enrichment was developed. The capacity of the extraction channels - donor and acceptor, respectively - were reduced from originally 10 to 1.65 mu L. The acceptor channel surface was covered with a gold layer enabling immobil
Popular Abstract in Swedish De flesta barn som insjuknar i epilepsi tillfrisknar eller blir anfallsfria med hjälp av antiepileptisk medicin. Hos drygt en fjärde del av barnen blir epilepsin svårbehandlad och anfallskontroll är svår att uppnå. Dessa barn ska i första hand erbjudas möjlighet till epilepsikirurgisk utredning och behandling. När epilepsikirurgisk behandling inte är möjlig att utföra eWhen anti-epileptic drugs fail, and epilepsy surgery is found unfeasible or ineffective, there remains a group of at least 25% of children with epilepsy in whom seizure control cannot be achieved. Vagus nerve stimulation (VNS) is an adjunctive treatment for medically refractory epilepsy. It is an implantable, multi-programmable pulse generator that delivers current electrical stimulation to the va
We discuss the preimaginal development of the mosquito Aedes aegypti from the point of view of the statistics of developmental times and the final body-size of the pupae and adults. We begin the discussion studying existing models in relation to published data for the mosquito. The data suggest a developmental process that is described by exponentially distributed random times. The existing data s
In this paper, enthalpy-entropy compensation (EEC) during the association of two molecules is studied by minimising model systems with molecular mechanics (MM) or quantum mechanics (QM), calculating translational, rotational, and vibrational contributions to the enthalpy and entropy with standard statistical-mechanics methods, using the rigid-rotor harmonic-oscillator approach. We start with simpl
In this double-blind, placebo-controlled study, 363 patients with untreated multiple myeloma were randomized to receive either melphalan-prednisone and thalidomide (MPT) or melphalan-prednisone and placebo (MP). The dose of melphalan was 0.25 mg/kg and prednisone was 100 mg given daily for 4 days every 6 weeks until plateau phase. The dose of thalidomide/placebo was escalated to 400 mg daily until
Objective: Case management has since the 1970s been widely used to co-ordinate services for mental health patients. The methodology has expanded to support patients in many different types of conditions. This study is one of very few randomized trials on case management in a European setting. It examined the impact of case management on substance abuse and use of service after discharge from cour
Early erythroblasts from patients with refractory anemia (RA) and RA with ringed sideroblasts (RARS) show constitutive mitochondrial release of cytochrome c. Moreover, mature erythroblasts in RARS, but not in RA, display aberrant accumulation of mitochondrial ferritin (MtF). We analyzed cytochrome c release, MtF expression, and gene expression during erythrold differentiation in bone marrow cells
Acetohydroxyacid synthase (AHAS) is the target enzyme for a number of herbicides. A S653N mutation in the AHAS gene results in an increased tolerance to imidazolinone herbicides. We have investigated the use of the mutated gene as selection gene for potato transformation. This resulted in a transformation system with a very high transformation frequency and low rate of escapes. The mutated AHAS ge
