The extent of today's land degradation and desertification in the arid, semi-arid. and sub humid regions of China is a serious threat to the social and economic development in these areas. A national programme for monitoring and classification of drylands has been implemented by the Chinese Academy of Science. Areas are classified into degrees of desertification on the basis of vegetation cove
We present a method to produce small pitch gratings for X-ray interferometric imaging applications, allowing the phase sensitivity to be increased and/or the length of the laboratory setup to be minimized. The method is based on fabrication of high aspect ratio silicon microstructures using deep reactive ion etching (Bosch technique) of dense grating arrays and followed by conformal electroplating
Climate change influences population demography by altering patterns of gene flow and reproductive isolation. Direct mutation rates offer the possibility for accurate dating on the within-species level but are currently only available for a handful of vertebrate species. Here, we use the first directly estimated mutation rate in birds to study the evolutionary history of pied flycatchers (Ficedula
Ionogels offer huge potential for a number of applications including wearable electronics and soft sensors. However, their synthesis has been limited and often relies on non-renewable or non-biocompatible components. Here we present a novel two-component ionogel made using just deep eutectic solvents (DESs) and cellulose. DESs offer a non-volatile alternative to hydrogels with highly tuneable prop
Due to globalization, increasing amounts of water are traded across borders as virtual water embodied in traded products. The thesis traces global water trade patterns at different levels of income between 1990 and 2015 in order to test whether developed countries outsource their water-intensive production to less developed countries increasing global water use in the process. The research problem
Objective: To examine and compare the adult outcome in a representative sample of hospitalized adolescent-onset psychoses including occupational and social aspects. Method: A total of 81 patients with a first episode of early-onset psychosis (before age 19 years) presenting to the University Hospital of Lund, Sweden, between 1982 and 1993 were followed up an average of 10.5 years (range 5.1-18.2)
The major aim of the study was to investigate whether differences concerning acceptance of dental treatment and amnesia after rectal sedation with midazolam can be explained by temperament traits in the child. Fifty children (1.5- 4.0 years), consecutively referred for dental extractions because of dental trauma or caries, were sedated with midazolam 0.3 mg kg(1) rectally. Level of sedation (state
The clinical features of delta infection were analysed retrospectively in 191 hepatitis B surface antigen (HBsAg) carriers and 592 cases of acute hepatitis B seen over 11 years in the Swedish town of Malmo (population 250 000). With a few exceptions delta infections occurred exclusively in drug addicts. In the chronic HBsAg-carriers the most common clinical manifestation was an episode of acute he
An increasing incidence of testicular cancer has been reported from several western countries during the last decades. According to current hypothesis testicular cancer is initiated during the foetal period and exposure to endocrine disruptors such as some persistent organic pollutants has been of concern. We have previously reported the results for concentrations of polychlorinated biphenyls (PCB
Nematodes, rotifers and tardigrades were collected on three nunataks (mountain peaks penetrating the ice sheet) in Vestfjella, on six nunataks; in Heimefrontfjella and on the Schirmacher Oasis in East Antarctica in the austral summers of 1996/97 and 2001/02. Most samples were taken on the nunatak Basen in Vestfjella where the Swedish station Wasa is located. The microfauna was patchily distributed
Magnesium chelatase (EC 6.6.1.1) catalyses the insertion of magnesium into protoporphyrin IX, the first unique step of the chlorophyll biosynthetic pathway. The enzyme is composed of three different subunits of approximately 40, 70 and 140 kDa. In barley (Hordeum vulgare L.) the subunits are encoded by the genes Xantha-h, Xantha-g and Xantha-f. In the 1950s, eight induced xantha-f mutants were iso
Previous studies have shown that the functional efficacy of intrastriatal transplants of fetal dopamine (DA) neurons in the rat Parkinson model depends on their ability to establish a new functional innervation of the denervated striatum. Here we report that the survival, growth, and function of the grafted DA neurons greatly depend on the severity of the lesion of the host nigrostriatal system. F

RELEVANCE Due to the rapid changes organizations in the software
Roten till cancer? Cancer är en ledande orsak till en stor mängd dödsfall i världen och därför en fruktad sjukdom. Forskningen gör dock framsteg och man kommer allt närmre svaren på gåtorna. På senare år har det föreslagits att en speciell typ av celler, cancerstamceller, är drivande och ligger bakom flera av cancersjukdomarnas egenskaper. Alla organismer är uppbyggda av celler, den stora majoriIn recent years increasing evidence supporting the stem cell hypothesis have emerged and cancer stem cells (CSCs) have been reported to have been isolated in a wide variety of cancers. This CSC population has been attributed to contribute to the therapeutic resistance of many cancers and it is thus of great interest to find new therapeutic options targeting these cells. In ileal carcinoids however
Priming effects have gotten revived interest in the last decade due to the concerns of global warming. Priming are defined as an increase in decomposition of soil organic matter due to the addition of organic or mineral substances. The worldwide used herbicide glyphosate is rapidly degraded by microorganisms. Hence, it might give rise to priming effects in soils. This was tested by adding glyphosa
Supercritical heat transfer deterioration can be found in active regenerative cooling processes. Thermal pyrolysis occurs once the temperature of the hydrocarbon fuel exceeds a certain value. To investigate the influence of thermal pyrolysis on the heat transfer behavior and flow-upward characteristics in a rectangular channel, the wall temperature distribution, thermal acceleration, mass fraction
The etiology of hereditary ataxia syndromes is heterogeneous, and the mechanisms underlying these disorders are often unknown. Here, we utilized exome sequencing in two siblings with progressive ataxia and muscular weakness and identified a novel homozygous splice mutation (c.3020-1G > A) in neurofascin (NFASC). In RNA extracted from fibroblasts, we showed that the mutation resulted in inframe ski
