We report the first investigation of cool-core properties of galaxy clusters selected via their Sunyaev–Zel’dovich (SZ) effect. We use 13 galaxy clusters uniformly selected from 178 deg2 observed with the South Pole Telescope (SPT) and followed up by the Chandra X-ray Observatory. They form an approximately mass-limited sample (>3× 1014 M h−1 70 ) spanning redshifts 0.3 < z < 1.1. Using previou...

Little research has examined ultra-endurance swimming performances. The 'English Channel Swim', where swimmers have to cover a distance of 32 km between England and France represents a unique long-distance, open-water, sea-swimming challenge, and each year swimmers from all over the world try to succeed in this challenge. The best times in minutes and the nationality of successful men and women...

Why do some clusters have cool cores while others do not? In this paper, cosmological simulations, including radiative cooling and heating, are used to examine the formation and evolution of cool core (CC) and non-cool core (NCC) clusters. Numerical CC clusters at z = 0 accreted mass more slowly over time and grew enhanced cool cores via hierarchical mergers; when late major mergers occurred, t...

The research investigated the role of complexity and the hot-cool distinction in cognitive development. The 120, 3- to 6-year-old children completed four hot tasks, which involved an affective component and three cool tasks, which did not. All tasks included binary- and ternary-relational items. Complexity was a major source of difficulty on all tasks, especially for younger children. Consisten...

This technical report presents the specification of a programming language Cool: the Core Object-Oriented Language. Cool is a small language but retains many of the features of modern class-based object-oriented languages, including primitive types, classes, inheritance, objects, instance variables and methods, dynamic method binding, null and arrays, etc.. The specification for Cool in this re...

The purpose of this study is to investigate workers' responses to work in hot-humid conditions while wearing protective clothing commonly used by the asbestos removal industry, and to evaluate the effects of resting between work bouts in a cool environment on the physiological strain. Seven male students wearing impermeable protective clothing and air masks were exposed to the following conditi...

calcareous deposits formed on the part of steel that cathodic reactions occur on their surface. the purpose of this research is an investigation of the effect of potential on crystal form of the calcareous deposits and effect of them on the corrosion resistance of the mild steel in natural seawater. the electrochemical tests such as impedance and polarization tofel tests were used in order to i...

Seawater-soluble nutrient fractions of aerosols better represent the contribution of aerosol dry deposition to the nutrient load from this source to the ocean than any estimates based on aerosol nutrients leached in pure water or acidic solutions. To understand the solubility difference between seawater and pure water, 31 pairs of aerosol samples collected from the Gulf of Aqaba were extracted ...

The Atlantic killifish (Fundulus heteroclitus) is an environmental sentinel organism used extensively for studies on environmental toxicants and salt (NaCl) homeostasis. Previous research in our laboratory has shown that rapid acclimation of killifish to seawater is mediated by trafficking of CFTR chloride channels from intracellular vesicles to the plasma membrane in the opercular membrane wit...

In recent years, capital and operating costs of seawater desalination plants have decreased remarkably. However, production of potable water from seawater by reverse osmosis membrane desalination remains 2 to 3 times the cost of desalting brackish water, reclaiming wastewater, or importing fresh water even over long distances. In addition, rejection of boron by seawater RO membranes is generall...
