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

, 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 ...

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

مدل‌سازی 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,

Response to comment of Albarède and colleagues

Internet 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.

Positron emission in PbPb and PbU collisions

Physics 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.

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

Internet 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

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

Nuclear 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 ...

Investigation of the concentration and isotopic composition of inputs and outputs of Pb in waters at an upland catchment in NE Scotland [PDF]

, 2005
As a consequence of the accumulation of anthropogenic Pb in upland catchments, there has been much recent concern about the potential mobilisation and transport of Pb from the soils to receiving waters and also the possible harmful effects that this ...

Correlations and fluctuations in Pb+Pb collisons

Nuclear Physics B - Proceedings Supplements, 2001
Results on two-particle correlations, deuteron production, event anisotropy and event-by-event fluctuations of p_T/ and K/ pi were obtained by the NA49 experiment in Pb+Pb collisions at 158 A.GeV beam energy. The interpretation of the measurements is discussed in light of the search for deconfinement.
