knowledge of transport and degradation of polycyclic aromatic hydrocarbons (pahs) is important in assessing pah contamination of soils and water resources. the transport of naphthalene, anthracene, pyrene and phenanthrene was determined in a contaminated calcareous soil obtained from the shadegan wetland (khozestan, iran) considering a column study in laboratory conditions. the pahs were added ...

Despite the renewed interest in ion implantation doping of GaN, efficient electrical activation remains a challenge. The lattice location 27Mg is investigated GaN different types as function temperature and fluence at CERN's ISOLDE facility. amphoteric nature Mg elucidated, i.e., concurrent occupation substitutional Ga interstitial sites: following room ultra-low (≈2 × 1010 cm−2) implantation, ...

Onion is one of the most important bulb crop grown all over India. It belongs to family Alliaceae and locally known as Pyaj. An experiment was conducted determine effect micronutrients on growth (Allium cepa L.) during Rabi season 2019-2020 at Horticultural Research centre Sardar Vallabhbhai Patel University Agriculture Technology, Meerut (U.P.). The laid out in Randomized Block Design (RBD) wi...

Discussions This discussion paper is/has been under review for the journal Geoscientific Model Development (GMD). Please refer to the corresponding final paper in GMD if available. Abstract Accurate estimates of soil organic carbon (SOC) stocks are required to quantify carbon sources and sinks caused by land use change at national scale. This study presents a novel robust kriging method to prec...

AIM The aim of this study was to evaluate with light microscopy the healing process of third-degree burns on diabetic rats treated with polarized light (λ400-2000 nm, 20 or 40 J/cm(2)/session, 40 mW/cm(2), 2.4 J/cm(2)/min, 5.5-cm beam diameter). BACKGROUND Uncontrolled diabetes mellitus causes severe disruption of the body's metabolism, including healing. Polarized light sources have been sho...

We observed the non-interacting edge-on galaxy NGC 5907 in total power and polarized radio continuum emission at wavelengths of λλ 2.8, 6.2, and 20 cm, using the VLA and the Effelsberg 100-m telescope. The total power emission of the galaxy shows (after subtraction of a double background source in the southern half) its maximum intensity slightly shifted to the north with respect to the optical...

1. To study the potential for complementarity in nitrogen acquisition from different soil depths, we injected an isotope tracer ( 15 NH 4 Cl) at 5 and 20 cm depths in plant communities containing Achillea millefolium L. and Festuca ovina L. or Phleum pratense L. and Trifolium pratense L. in monocultures and two-species mixtures. 2. In monoculture, Festuca and Phleum took up tracer at 5 and 20 c...

Hyperosmotic agents have shown great potential in tissue optical clearing. However, the low efficiency of the permeation in biological tissues seriously restricts its application in reality. The synergy of sonophoresis as a penetration enhancer and hyperosmotic agents, 20% glucose (G) and 20% mannitol (M), in optical clearing has been investigated by analyzing the variation of the attenuation c...
