Collective flow in 2.76 A TeV and 5.02 A TeV Pb+Pb collisions [PDF]

open access: yes, 2017
In this paper, we study and predict flow observables in 2.76 A TeV and 5.02 A TeV Pb +Pb collisions, using the iEBE-VISHNU hybrid model with TRENto and AMPT initial conditions and with different forms of the QGP transport coefficients.

Pollution indices of heavy metals in agricultural soils irrigated with raw sewage (Meshginshahr, Ardabil) [PDF]

open access: yesمدل‌سازی و مدیریت آب و خاک, 2023
Introduction As a great reservoir of nutrients and pollutants, soil plays an important role in health and socio-ecological sustainability. Soil pollution increases as a result of the entry of heavy metals from operations such as agriculture, urbanization,

Laser microdissection as a new approach to prefertilization genetic diagnosis [PDF]

open access: yes, 2000
The genetic status of oocytes can be determined by polar body (PB) analysis. Following PB extraction, a genetic evaluation is performed. As each PB contains the complementary genetic material of the oocyte, PB analysis reveals information about its ...

Fractionation of lead in soil by isotopic dilution and sequential extraction [PDF]

open access: yes, 2011
‘Reactivity’ or ‘lability’ of lead is difficult to measure using traditional methods. We investigated the use of isotopic dilution with 204Pb to determine metal reactivity in four soils historically contaminated with contrasting sources of Pb, including (

Positron emission in PbPb and PbU collisions

open access: yesPhysics Letters B, 1978
Abstract We present quantitative calculations of positron emission dynamically induced in the collision of PbPb and PbU. The results are compared with recent measurements, yielding evidence for new processes characteristic for quantum electrodynamics of strong fields.

HEALTH RISK ANALYSIS OF LEAD LEVELS (Pb) IN GREEN LEAFY VEGETABLES FROM TRADITIONAL MARKETS AND SUPERMARKET IN SEMARANG CITY: A PRELIMINARY STUDY

open access: yesJurnal Riset Kesehatan, 2020
Samples of Green Spinach (Amaranthus gangeticus) Kale or Water Spinach (Ipomoea aquatica) and Green Mustards (Brassica rapa I. Subsp. Perviridis Bayley) were collected from three traditional markets and one supermarket in Semarang City, Central Java. The

Response to comment of Albarède and colleagues

open access: yesInternet Archaeology, 2023
Our purpose is to better understand the actions and behaviours of people in the past, often with a focus on ancient economies, and we are willing to use tools from any discipline that allow us to explore these issues.

Comment on Mints not Mines: a macroscale investigation of Roman silver coinage by J.R. Wood, M. Ponting, and K. Butcher

open access: yesInternet Archaeology, 2023
Wood et al. (2023), hereinafter WPB, unveils a number of historical issues relevant to Roman economy and metallurgy based on trace element and Pb isotope abundance data on a large set of important coins minted during the Roman Empire (Ponting and Butcher

Canonical Description of Strangeness Enhancement from p-A to Pb-Pb Collisions [PDF]

open access: yes, 2000
We consider the production of strange particles in Pb-Pb and p-A collisions at the SPS energy reported by the WA97 experiment. We show that the observed enhancement of strange baryon and antibaryon yields in Pb-Pb collisions relative to p-Be and p-Pb can

Electroweak bosons in Pb+Pb and p+Pb collisions [PDF]

open access: yesNuclear and Particle Physics Proceedings, 2016
Electroweak boson (W, Z, ) measurements in Pb+Pb collisions at p sNN = 2:76 TeV and in p+Pb collisions at p sNN = 5:02 TeV are presented with the ATLAS detector at the LHC. In Pb+Pb, electroweak boson yields are shown to be independent of centrality. Di erential measurements in absolute pseudorapidity are used to investigate nuclear e ects to the free ...
