In models for hadron collisions based on string hadronization, the strings are usually treated as independent, allowing no interaction between the confined colour fields. In studies of nucleus collisions it has been suggested that strings close in space can fuse to form "colour ropes". Such ropes are expected to give more strange particles and baryons, which also has been suggested as a signal for
Most research on child pornography use has been basedonselected clinical or criminal justice samples;riskfactors for child pornography use in the general population remain largely unexplored. In this study, we examined prevalence, risk factors,andcorrelates of viewingdepictions of adult–child sex in a population-representative sample of 1,978 young Swedish men(17–20 years,Mdn=18 years, overall res
Certain personality traits predispose to criminal behavior (CB). We further clarify this relationship in a Swedish national sample.
Working across knowledge-based research programmes, rather than institutional structures, should be central to interdisciplinary research. In this paper, a novel framework is proposed to facilitate interdisciplinary research, with the goals of promoting communication, understanding and collaborative work. Three core elements need to be addressed to improve interdisciplinary research: the types (fo
Gastrointestinal symptoms have a major impact on the quality of life and are becoming more prevalent in the western population. The enteric nervous system (ENS) is pivotal in regulating gastrointestinal functions. Purinergic neurotransmission conveys a range of short and long-term cellular effects. This study investigated the role of the ADP-sensitive P2Y13 receptor in lipid-induced enteric neurop
The objective of this study was to examine the association of the intensity of treatment, ranging from high-dose intensive factor VIII (FVIII) treatment to prophylactic treatment, with the inhibitor incidence among previously untreated patients with severe hemophilia A. This cohort study aimed to include consecutive patients with a FVIII activity <0.01 IU/mL, born between 2000 and 2010, and observ
Interactions with bacterial lipopolysaccharide (LPS), both in aqueous solution and in lipid membranes, were investigated for a series of amphiphilic peptides derived from the C-terminal region of human thrombin, using ellipsometry, dual polarization interferometry, fluorescence spectroscopy, circular dichroism (CD), dynamic light scattering, and z-potential measurements. The ability of these pepti
Chinese universities have undergone a massive transformation in recent decades. In addition to a dramatic increase in the number of universities and students, universities have shifted from primarily providing education to emphasizing research. Omnipresent political control is to be replaced by stronger academic self-organization. The result so far is a growing stratification of Chinese universiti
Technology that facilitates rapid investigation of solid phase extraction protocols using very small amounts of sorbent can save both time and money. The microfabricated ISET (Integrated Selective Enrichment Target) interfaced with MALDI mass spectrometry is able to provide an efficient, economic and generic optimization process for SPE sample preparation. The SPE is performed in a rapid and paral
Background. Peer deviance (PD) is associated with risk for drug abuse (DA). Is this association causal? Method. DA was recorded in official records. PD was defined as the percentage of peers residing in small communities with future DA registrations. We examined offspring in families whose community PD changed when the offspring was 0-15 years of age and then examined families where cousins or sib
Short-term very intensive storms in the years 1980-2007 from rain gauges in Malmo have been analysed to find intensities of long return periods and to investigate trends. Observations from different stations have been pooled into series to which probability functions have been adjusted. Quality control of short-term precipitation records is emphasized. In order to investigate whether high rain int
Artikeln undersöker människors förhållningssätt till uppslagsverk och encyklopedier i ett livshistoriskt perspektiv under en period när encyklopedier har genomgått dramatiska förändringar. En frågelista som skickats till fasta så kallade meddelare knutna till Folklivsarkivet i Lund har använts som metod. Svaren har analyserats med hjälp av posthumanistisk teori. Analysen visar de sätt som tryckta Encyclopaedias are artefacts that both define and are defined by the culture in which they are produced and used. Encyclopaedias mirror the time of their creation, at the same time as understanding and use of encyclopaedias is tied to both time and space. From the 19th century until the present day encyclopaedias have changed from exclusive and costly Collections of books kept mainly in libraries
Plasmodium falciparum like other organisms is dependent on polyamines for proliferation. Polyamine biosynthesis in these parasites is regulated by a unique bifunctional S-adenosylmethionine decarboxylase/ornithine decarboxylase (PfAdoMetDC/ODC). Only limited biochemical and structural information is available on the bifunctional enzyme due to the low levels and impurity of an instable recombinantl
Epidemiological studies indicate that risks of certain cancers are increased in individuals hospitalized for type 2 diabetes mellitus (T2DM), which may not be representative of the entire population of T2DM patients as most of them are treated in primary health cares. To examine the subsequent cancer risk in individuals with T2DM from hospitals and primary health cares, and in their siblings and s
Variants in the growth factor receptor-bound protein 10 (GRB10) gene were in a GWAS meta-analysis associated with reduced glucose-stimulated insulin secretion and increased risk of type 2 diabetes (T2D) if inherited from the father, but inexplicably reduced fasting glucose when inherited from the mother. GRB10 is a negative regulator of insulin signaling and imprinted in a parent-of-origin fashion
AIM: To investigate the mechanism of interleukin (IL)-6 secretion through blocking the IL-17A/IL-17A receptor (IL-17RA) signaling pathway with a short hairpin RNA (shRNA) in hepatic stellate cells (HSCs) in vitro. METHODS: HSCs were derived from the livers of adult male Sprague-Dawley rats. IL-6 expression was evaluated using real-time quantitative polymerase chain reaction and enzyme linked immun
The short-range structures of hydrated and dry samples of the proton-conducting, cubic-structured, acceptor-doped perovskites BaM0.10Zr0.90O2.95 (M=Y, In, Sc and Ga), and, for comparison, BaZrO3, have been investigated using infrared and Raman spectroscopy. The results show that the acceptor-doping leads to local structural distortions of the average cubic structure, most likely related to tilts o
Numerous Neoproterozoic mafic dykes, referred to as the Dashigou swarm, are identified in the central and southeastern parts of the North China craton (NCC). They are 305-010 degrees trending dykes, with widths of similar to 10-100 m and exposed lengths of several to >10 km. Precise U-Pb isotope dilution thermal ionization mass spectrometry (ID-TIMS) measurements on baddeleyite grains separated fr
Non-drinkers among youth in Sweden have increased markedly during the last 15 years. The aim of this study is to investigate the temporal association between region of origin among Swedish youth and rates of non-drinking.
