We measured the abundances of Sr and rare earth elements (REEs) in the matrices of five CV3 carbonaceous chondrites: Meteorite Hills (MET) 00430, MET 01070, La Paz ice field (LAP) 02206, Asuka (A) 881317 and Roberts Massif (RBT) 04143. In the MET 00430 and MET 01074 matrices, the Sr/CI and light REE (LREE, La–Nd)/CI ratios positively correlate with the amounts of Ca-rich secondary minerals, whi...

Abstract Purpose Information about particle size distribution (PSD) and soil texture is essential for understanding drainage, porosity, nutrient availability, trafficability. The sieve-pipette/gravimetric method traditionally used analysis labour-intensive resource-intensive. X-ray fluorescence (XRF) spectrometry may provide a rapid alternative. study’s aim was to examine the use of XRF determi...

The model-date of a nuclear material is an important signature in a nuclear forensic investigation. Assuming the material is homogeneous, this parameter is fixed and exact, but it may or may not be the same as the purification date. The decay of a radioactive parent to a radioactive or stable daughter is the basis of the radiochronometers that record this model-date. If upon purification, only ...

Abstract The Travaux Préparatoires insist upon the close nexus between Articles 9, 10, and 11 along with several other provisions of UNCRC that protect bond child parent. This chapter analyses content Article 9 in relation to general principles Child rights, related international human rights treaties materials, sets out four main attributes right, as a child, not be separated from one’s parent...

OBJECTIVE The goal of this study was to evaluate the effect of a parent-focused behavioral intervention on parent and child eating changes and on percentage of overweight changes in families that contain at least one obese parent and a non-obese child. RESEARCH METHODS AND PROCEDURES Families with obese parents and non-obese children were randomized to groups in which parents were provided a ...

Drylands typically have distinctive vegetative patterns that reflect the underlying physical landscape. We use a geopedological classification to organize the landscape into five categories from broad scale to fine scale: (1) physiographic divisions which describe regional topography, such as mountains and basin floors; (2) regolith type which identifies residuum versus transported sediments; (...
