Measurement of jet activity in top quark events using the eμ final state with two b-tagged jets in pp collisions at √s=8 TeV with the ATLAS detector

Measurements of the jet activity in tt¯ events produced in proton-proton collisions at s=8 TeV are presented, using 20.3 fb−1 of data collected by the ATLAS experiment at the Large Hadron Collider. The events were selected in the dilepton eμ decay channel with two identified b-jets. The numbers of additional jets for various jet transverse momentum (pT) thresholds, and the normalised differential

Search for supersymmetry in a final state containing two photons and missing transverse momentum in √s = 13 TeV pp collisions at the LHC using the ATLAS detector

A search has been made for supersymmetry in a final state containing two photons and missing transverse momentum using the ATLAS detector at the Large Hadron Collider. The search makes use of 3.2fb-1 of proton-proton collision data collected at a centre-of-mass energy of 13 TeV in 2015. Using a combination of data-driven and Monte-Carlo-based approaches, the Standard Model background is estimated

Clothing Insulation Required for Energy Efficiency (IREQee) and Thermal Comfort

Thermal comfort has direction implications for energy efficiency and sustainable development. From a global perspective, about 40% of total primary energy is used in buildings, contributing to more than 30% of CO2 emissions [1]. The fact that the common practices of clothing choices have impact on energy efficiency is ignored [2-3]. This paper analyzed and proposed clothing insulation required for

Effects of global climate change on health of occupational populations: a review

Climate change has become one of the most serious challenges for human society in the 21st century. Due to the particularity of their own, occupational workers are more affected by climate change, which can cause disease, injury and even death. More importantly, climate change can indirectly lead to the reduction of work time and a decrease in labor productivity, which affects the social and econo

Whole body heat balance and local insulation required to prevent extremity cooling in extremely cold environments

IntroductionLocal cooling in winter conditions is a sensitive and early warning of whole body cooling. Previous studies showed that the equilibrium temperature for the 5th finger is strongly affected by both temperature and insulation. The international standard ISO 11079 is used to calculate clothing insulation required for the whole body based on heat balance equations. However, it does not prov

Novel process technologies for conversion of carbon dioxide from industrial flue gas streams into methanol

This research aims to develop efficient process technologies that are capable of converting/utilising CO2 streams into energy-rich liquid products (fuels). This would result in better solutions with near-zero-carbon-emissions level. From an energetic and economic point of view, methanol synthesis from CO2 is a competitive alternate to methanol production from biomass. Our work considers the CO2 ba

Genetic characterization of human immunodeficiency virus type 1 transmission in the Middle East and North Africa

Background: The HIV-1 spread in the Middle East and North Africa (MENA) has not been previously characterised using the phylogenetic approach. The aim of the current study was to investigate the genetic diversity and domestic transmission of HIV-1 in the MENA. Methods: A total of 2036 HIV-1 sequences available in Genbank and collected in the MENA during 1988–2016 were used together with 715 HIV-1

Early fledging mortality and the timing of juvenile dispersal in the marsch tit Parus palustris

Family flocks of Marsh Tits Parus palustris in southern Sweden kept together until 11-15 d after fledging and stayed within the former territory of the parents. Mortality in the family flocks was low in one year (1.2-3.6%) but higher in another (18.6%). This level of mortality is compared with post-dispersal mortality in other species of tits. The occurrence of a parent-offspring conflict with reg

Effect of experimentally altered brood size on frequency and timing of second clutches in the great tit

Brood size in the Great Tit (Parus major) was manipulated (increased, decreased, or unchanged) when nestlings were 5 days old. Both the frequency of second clutches and the interbrood interval were affected. The number of nestlings and hatching date, but not nestling and female mass, differed between first broods followed and not followed by second clutches. Hatching date and the number of nestlin

Effects of Dispersal Date on Winter Flock Establishment and Social Dominance in Marsh Tits Parus palustris

(1) We studied the effect of sex, size, age and prior occupancy on social dominance winter flock establishment in a population of marsh tits Parus palustris L. (2) When sex was accounted for, time of establishment in the winter flock-prior occupancy, was critical for the outcome of later aggressive interactions juveniles within flocks. Residents won all interactions with intruders irrespective con
