This Letter presents a search for quantum black-hole production using 20.3 fb(-1) of data collected with the ATLAS detector in pp collisions at the LHC at root s = 8 TeV. The quantum black holes are assumed to decay into a final state characterized by a lepton (electron or muon) and a jet. In either channel, no event with a lepton-jet invariant mass of 3.5 TeV or more is observed, consistent with
This paper presents a search for a new heavy particle produced in association with a top or antitop quark. Two models in which the new heavy particle is a color singlet or a color triplet are considered, decaying, respectively, to (t)over-barq or tq, leading to a resonance within the t(t)over-bar + jets signature. The full 2011 ATLAS pp collision data set from the LHC (4.7 fb(-1)) is used to searc
This paper presents a search for new particles in events with one lepton (electron or muon) and missing transverse momentum using 20.3 fb(-1) of proton-proton collision data at root s = 8 TeV recorded by the ATLAS experiment at the Large Hadron Collider. No significant excess beyond Standard Model expectations is observed. A W' with Sequential Standard Model couplings is excluded at the 95% confid
Background: The limitations of serum testosterone and estradiol (E-2) measurements using nonextraction platform immunoassays (IAs) are widely recognized. Switching to more specific mass spectrometry (MS)-based methods has been advocated, but directly comparative data on the two methods are scarce. Methods: We compared serum testosterone and E-2 measurements in a large sample of middle-aged/elderly
Purpose: The excess cardiovascular morbidity associated with schizophrenia is attributed to an interplay between behavioural (physical inactivity, unhealthy diet, substance abuse), genetic and illness related factors, as well as the effects of antipsychotic treatment. Patients have limited access to physical healthcare with less opportunity for cardiovascular risk prevention and treatment programm
A search has been performed for pair production of heavy vectorlike down-type (B) quarks. The analysis explores the lepton-plus-jets final state, characterized by events with one isolated charged lepton (electron or muon), significant missing transverse momentum, and multiple jets. One or more jets are required to be tagged as arising from b quarks, and at least one pair of jets must be tagged as
A search is reported for the pair production of a new quark b' with at least one b' decaying to a Z boson and a bottom quark. The data, corresponding to 2.0 fb(-1) of integrated luminosity, were collected from pp collisions at root s = 7 TeV with the ATLAS detector at the CERN Large Hadron Collider. Using events with a b-tagged jet and a Z boson reconstructed from opposite-charge electrons, the ma
The fecal microbiota of two healthy Swedish infants was monitored over time by terminal restriction fragment length polymorphism (T-RFLP) analysis of amplified 16S rRNA genes. Principal component analysis (PCA) of the T-RFLP profiles revealed that the fecal flora in both infants was quite stable during breast-feeding and a major change occurred after weaning. The two infants had different sets of
The cellular and molecular pathways initiated by traumatic brain injury (TBI) may compromise the function and structural integrity of mitochondria, thereby contributing to cerebral metabolic dysfunction and cell death. The extent to which TBI affects regional mitochondrial populations with respect to structure, function, and swelling was assessed 3 hours and 24 hours after lateral fluid-percussion
Background: ABO genotyping is complicated by the remarkable diversity at the ABO locus. Recombination or gene conversion between common alleles may lead to hybrids resulting in unexpected ABO phenotypes. Furthermore, numerous mutations associated with weak subgroups and nondeletional null alleles should be considered. All known ABO genotyping methods, however, risk incorrect phenotype predictions
The determination of elemental abundances plays an important role inunderstanding the atmospheric processes that lead to anomalies inspectra of chemically peculiar stars. Ongoing study of the HgMn star χ Lupi has defined much of the elemental abundance distribution but progress is dependent upon the availability and accuracy of the atomic data. Here we present experimentally determined wavelengths
The first ESR spectroscopic evidence of a bimolecular homolytic substitution (SH2) reaction in a 77 K solid phase was presented, where radicals were substituted for the CH3 group of methylsilane and methylgermane (CH3XD3, X = Si, Ge). The radicals were generated by in situ UV-photolysis of CD3I in the solid CH3XD3 in an ESR cavity at 77 K. Using the selectively deuterium labeled compounds, it was
In 1999, seven dark-bellied brent geese Branta bemicla bemicla were followed during spring migration from western Europe to Arctic Russia using satellite telemetry. For six of the birds we were also able to monitor their summer stay at the Taymyr Peninsula, and for five birds part of their autumn migration was recorded. In this article, we report on site use during summer and spring/autumn migrati
Denna uppsats syftar till att undersöka i vilken utsträckning arbetstidslagstiftningen i Thailand och Sverige skyddar rätten till decent working time för hushållsarbetare. För att uppnå detta jämförs arbetstidslagstiftningen i de två länderna med hur decent working time definieras inom den internationella arbetsrätten. Denna analys utgör grunden för en diskussion om arbetstidsregleringen för hushåThis paper explores the extent to which working time legislation in Thailand and Sweden protects the right to decent working time for domestic workers. This is examined through a comparative analysis of the national working time legislation in the two countries and the parameters of decent working time established in international labor law. This is the basis for a subsequent discussion on the re
Issues related to attribution of profits already exist in the traditional economic framework and are of a different nature, however these issues seem to become more bothersome in transactions conducted in e-commerce context, with an electronic economy. The matter is similar to the traditional economic problems in regard to transfer pricing adjustments; however these issues are much more complex du
Aim: To investigate the effect of general anaesthesia on the TCI-dosage, the depth of anaesthesia and the need for hemodynamic treatment. A comparison between general anaesthesia (GA) alone and general anaesthesia combined with epidural anaesthesia (GA+EDA). Background: There are some uncertainties in the literature whether epidural anaesthesia has any effect on general anaesthesia governed by Ta
Denna uppsats syfte är att kritiskt granska de rättsliga åtgärder som vidtogs av de svenska beslutsfattarna i samband med hiv/aids-epidemin under 1980-talet. Uppsatsen har koncentrerats kring åtgärder som hade betydelse för män som har sex med män (MSM). Metoden har varit att med diskursanalytiska verktyg ge en idé om den samhälleliga respektive rättsliga synen på MSM, och hur den i sin tur kom atThe purpose of this essay is to critically review the actions taken by the Swedish authorities in connection to the HIV/AIDS epidemic during the 1980s. The essay concentrates on the measures taken by the authorities that are relevant for men who have sex with men (MSM). Based on discourse analysis, the paper attempts to determine the social and legal view of MSM and how this view came to affect th
