Lactones, cyclic esters of hydroxycarboxylic acids, are interesting biofuel candidates as they can be made from cellulosic biomass and have favorable physical and chemical properties for distribution and use. The reactions of γ-valerolactone (GVL), γ-crotonolactone (2(5H)-F), and α-methyl-γ-crotonolactone (3M-2(5H)-F) with Cl, OD, and O3 were investigated in a static chamber at 700 Torr and 298 ±
The dijet production cross section for jets containing a b-hadron (b-jets) has been measured in proton–proton collisions with a centre-of-mass energy of s=7 TeV, using the ATLAS detector at the LHC. The data used correspond to an integrated luminosity of 4.2fb-1. The cross section is measured for events with two identified b-jets with a transverse momentum pT> 20 GeV and a minimum separation in th
Measurements of the W±→ℓ±ν and Z→ℓ+ℓ− production cross sections (where ℓ±=e±,μ±) in proton–proton collisions at s=13 TeV are presented using data recorded by the ATLAS experiment at the Large Hadron Collider, corresponding to a total integrated luminosity of 81 pb−1. The total inclusive W±-boson production cross sections times the single-lepton-flavour branching ratios are σW+ tot=11.83±0.02 (stat
Purpose: In response to the need for hearing aids in low-income countries, an approach to provide hearing aids through trained community workers was developed. This study compares the effectiveness of the community-based approach with that of a centre-based approach. Methods: One hundred and forty adolescents (56% girls; 12–18 years; mean: 15 years) from eleven sub-districts participated in a clus
In this study, numerical simulations are conducted to investigate the effects of pin fin location, pin fin diameter, and pin fin shape on the target and pin fin surfaces heat transfer as well as friction factor in an improved Lamilloy cooling structure. The pin fin normalized location is varied from 0.35 to 0.65 while the pin fin diameter is changing from 15 mm to 60 mm. Cone-shaped pin fins are i
Platform ecosystems are becoming the locus of innovation-driven economies as technology-based platform within the ecosystem acts as the foundation for innovative product and services developed by the networked business community around that platform. At its core, a technology platform shows architectural properties, which once emerged in an industry could play as the de facto template for defining
The large rate of multiple simultaneous proton–proton interactions, or pile-up, generated by the Large Hadron Collider in Run 1 required the development of many new techniques to mitigate the adverse effects of these conditions. This paper describes the methods employed in the ATLAS experiment to correct for the impact of pile-up on jet energy and jet shapes, and for the presence of spurious addit
The membrane-anchoring subunit of Bacillus subtilis succinate:menaquinone reductase is a protein of 202 residues containing two protoheme IX groups with bis-histidine axial ligation. Residues Kis13, His28, His70, His113, and His155 are the possible heme ligands. The transmembrane topology of this cytochrome was analyzed using fusions to alkaline phosphatase. The results support a proposed model wi
ATLAS has measured two-particle correlations as a function of the relative azimuthal angle, Δφ, and pseudorapidity, Δη, in s=13 and 2.76 TeV pp collisions at the LHC using charged particles measured in the pseudorapidity interval |η|
The momentum-weighted sum of the charges of tracks associated to a jet is sensitive to the charge of the initiating quark or gluon. This paper presents a measurement of the distribution of momentum-weighted sums, called jet charge, in dijet events using 20.3 fb-1 of data recorded with the ATLAS detector at s=8 TeV in pp collisions at the LHC. The jet charge distribution is unfolded to remove disto
More than 95% of testicular cancer are cured but they are at increased long-term risk of cardiovascular disease. The risk of cardiovascular disease and treatment intensity was reported, but it is unknown whether this effect of cancer therapy is direct or indirect, mediated through androgen deficiency. Our aim was, therefore, to evaluate whether testicular cancer patients have increased the prevale
Background: The Tau PET ligand 18F-AV1451 has been shown to reliably detect paired helical filaments of tau in Alzheimer's disease, but it is not yet known whether it binds to the tau aggregates present in patients with mutations in the gene (MAPT) coding for the tau protein. Further, no study has yet compared the cerebral retention of 18F -AV1451 with the tau aggregates revealed using neuropathol
Human milk provides a very wide range of nutrients and bioactive components, including immune factors, human milk oligosaccharides, and a commensal microbiota. These factors are essential for interconnected processes including immunity programming and the development of a normal infant gastrointestinal microbiome. Newborn immune protection mostly relies on maternal immune factors provided through
OBJECTIVE:: Arterial stiffening increases with age and is associated with increased cardiovascular risk. Several risk factors have been shown to predict the development of arterial stiffening; however, a positive family history (FH+) of cardiometabolic disease (CMD) and hypertension has not been extensively studied. We hypothesize that FH+ of CMD plays a significant role in the development of arte
OBJECTIVES: The 22 countries of the East Mediterranean Region (EMR) have large populations of adolescents aged 10-24 years. These adolescents are central to assuring the health, development, and peace of this region. We described their health needs.METHODS: Using data from the Global Burden of Disease Study 2015 (GBD 2015), we report the leading causes of mortality and morbidity for adolescents in
OBJECTIVES: The Eastern Mediterranean Region faces several health challenges at a difficult time with wars, unrest, and economic change.METHODS: We used the Global Burden of Disease 2015 study to present the burden of diseases, injuries, and risk factors in the Eastern Mediterranean Region from 1990 to 2015.RESULTS: Ischemic heart disease was the leading cause of death in the region in 2015, follo
Using information from Swedish population registries, we attempt to decompose the shared environment (C) into four subcomponents: close family, family, household, and community. Among pairs differing in their genetic and geographical/household relationships, we examine three externalizing syndromes: drug abuse (DA), criminal behavior (CB), and alcohol use disorders (AUD). The best-fitting common p
Erythrocyte-binding antigens (EBAs) and P. falciparum reticulocyte-binding homologue proteins (PfRhs) are two important protein families that can vary in expression and utilization by P. falciparum to evade inhibitory antibodies. We evaluated antibodies at repeated time-points among individuals living in an endemic region in Nigeria over almost one year against these vaccine candidates. Antibody l
