Gift exchange, and the economy associated with it, is not restricted only to those tribal cultures where it has mostly been studied, but can also appear as an element of contemporary market economies. Yet despite this, the practical functioning of gift relationships between business partners is an understudied area. By studying the giving of corporate Christmas gifts, this article contributes to c
Acute lung injury (ALI) is an inflammatory disease with a high mortality rate. Although typically seen in individuals with sepsis, ALI is also a major complication in severe acute pancreatitis (SAP). The pathophysiology of SAP-associated ALI is poorly understood, but elevated serum levels of IL-6 is a reliable marker for disease severity. Here, we used a mouse model of acute pancreatitis–associate
A preparation method for silver-oxide containing nanoparticles is described. The suggested approach allows varying the oxidation degree from monoxide to an oxygen-rich state resembling superoxide The method is based on magnetron reactive sputtering and vapour aggregation, and utilizes silver-oxygen interaction in the vapour phase - prior to the nanoparticle aggregation from the vapour. Synchrotron
The formation of iron aluminide (FeAl) during the heating of Fe-40 at.% Al powder mixture has been studied using a differential scanning calorimeter. The effect of particle size of the reactants, compaction of the powder mixtures as well as the heating rate on combustion behavior has been investigated. On heating compacted discs containing relatively coarser iron powder, DSC data show two consecut
The inclusive top quark pair (t (t) over tilde) production cross-section sigma(t (t) over bar) has been measured in proton-proton collisions at root s = 7 TeV and root s = 8 TeV with the ATLAS experiment at the LHC, using t (t) over bar events with an opposite-charge e mu pair in the final state. The measurement was performed with the 2011 7 TeV dataset corresponding to an integrated luminosity of
The aetiology of oral lichen lesions is obscure. In this study the frequency of contact allergy to gold in 83 patients with oral lichen lesions was compared with that in two control groups, comprising 319 age- and gender-matched patients with dermatitis selected from files and 83 clinically examined dermatitis patients. All patients were tested epicutaneously with gold sodium thiosulphate. The two
Sedimentary records of invertebrate assemblages were obtained from a small lake in the Khibiny Mountains, Kola Peninsula. Together with a quantitative chironomid-based reconstruction of mean July air temperature, these data provide evidence of Holocene climate variability in the western sector of the Russian Subarctic. The results suggest that the amplitude of climate change was more pronounced in
At Sjölunda WWTP, a full-scale SBR for treatment of mesophilic sludge digester liquor has been operated almost a year with stable nitrite accumulation. Only nitritation of the sludge liquor is needed since the oxidized ammonium is denitrified in the first anoxic zone of the high-loaded activated sludge in the main plant. The process strategy was to have an ammonium set-point to end the aeration, a
In an experimental study we assessed if benthic bioturbating invertebrates affect the recruitment (hatching) of zooplankton from the sediment, and if this effect persists as differences in the zooplankton community in the water column, that is, if bioturbation quantitatively stimulates benthic-pelagic coupling. We investigated the effects of four different benthic invertebrates (Asellus aquaticus,
Background: Inflammation acting in synergy with brain ischemia aggravates perinatal ischemic brain damage. The sensitizing effect of pro-inflammatory exposure prior to hypoxia is dependent on signaling by TNF-alpha through TNF receptor (TNFR) 1. Adrenoceptor (AR) activation is known to modulate the immune response and synaptic transmission. The possible protective effect of (alpha) over tilde and
Ebba Ossiannilsson Lunds universitet Alastair Creelman, Linnéuniversitetet OER, MOOC, spelifiering och badgerörelsen Det är bara några av de trender vi har sett under 2012, mer kommer det att bli framöver och fort går det runt om i världen. I Horizon rapporten för 2012 förutsågs detta, men även augmented learning, individualiserat lärande, kursdesign och examination för lärande, sociala medier, le
Codes constructed from connected spatially coupled low-density parity-check code (SC-LDPCC) chains are proposed and analyzed. It is demonstrated that connecting coupled chains results in improved iterative decoding performance. The constructed protograph ensembles have better iterative decoding thresholds compared to an individual SC-LDPCC chain and require less computational complexity per bit wh
The genetic networks controlling stem cell identity are the focus of intense interest, due to their obvious therapeutic potential as well as exceptional relevance to models of early development. Genome-wide mapping of transcriptional networks in mouse embryonic stem cells (mESCs) reveals that many endogenous noncoding RNA molecules, including long noncoding RNAs (lncRNAs), may play a role in contr
Artikeln diskuterar moderniteten, samtiden, sociologin och förhållandet dem emellan samt hur samtiden betingar vetandet om denna samtid, och hur vetandet om samtiden gestaltas. Den epistemologiska konstellation som framkallas förstår jag som sociologisk samtidshermeneutik, eller samtidshermeneutisk sociologi. Dess grundantagande är: ju mer en kultur karakteriseras av kontingens (komplexitet, trans
OBJECTIVE- We studied differences between patients with latent autoimmune diabetes in adults (LADA), type 2 diabetes, and classical type 1 diabetes diagnosed after age 35 years. RESEARCH DESIGN AND METHODS- Polymorphisms in HLA-DQB1, INS, PTPN22, and CTLA4 were genotyped in patients with LADA (n = 213), type 1 diabetes diagnosed at >35 years of age (T1D(>35y); n = 257) or <20 years of age (T1D(<20
To investigate if the Swedish entry rules for pets to prevent the introduction of Echinococcus multilocularis (EM) are proportional (i.e. that their costs do not exceed the value of their benefits), a dichotomous-choice contingent valuation study was conducted. The study was performed before the first case of EM was detected in Sweden in February 2011. About 5000, randomly selected, Swedish citize
This paper describes the fabrication and initial characterization of an ultra-thin silicon PIN detector using a new technique in silicon nanotechnology. In collaboration with the Nuclear Physics Division and the Lund Nano Lab at Lund University, we have developed and manufactured ultra thin Delta E-detectors for spectroscopic applications. The fabrication process has been carried out using a doubl
