It is interesting to compare the quantity of Chernobyl fractions of 239+240Pu in the samples coming from the Wieprz River and Bug River valleys, despite the relatively large error associated with calculating this fraction.
The proportion of each component may vary, depending on quantity of each fraction and product standard (Sino IV, V and VI) [4], management of storage, and transportation section.
The carried out investigations of ZnS Cu obtained by SHS method with adding of NaCl in charge as flux have shown, that introduction of NaCl enables to increase quantity of fine fraction (50 500 nm) in material.
Total peak areas as estimates of relative quantity of respective fraction differed in the studied years, with an increase in April 2013 (Fig. 3a) and a decrease in April 2014 (Fig. 3b).
Equal quantities of various fractions of the synaptosomes isolated using DAT antibody including the starting material or control, the unbound fraction, the flow-through, the wash and the eluate were subjected to western analysis to assess relative dopaminergic versus non-dopaminergic synaptosomal purification.
Immunophenotyping of lymphocytes and monocytes including quantities of the fractions of HLA-DR expressing T cells and the level of CD40 expression on monocytes can differentiate between acute bacterial and viral infections.
We analysed the vertical and horizontal distribution of soil organic carbon (SOC) stocks, as well as the quantity of physically separated fractions including the free light (fLF), occluded light (oLF) and mineral associated fractions (MAF) in the mineral topsoil (A, AE) horizons.
The use of organic fertilizers not only reduces the quantity of the organic fraction that ends up in landfills (Lim et al. 2016), but also reduces the use of inorganic fertilizers (Lim et al. 2015).
First, the 4.0 g quantity of EtOAc soluble fraction of P. frutescens was subjected to HSCCC using HEMWat solvent (1.5 : 5 : 1 : 5, v/v).
