Various organic constituents extracted from wheat and from soil organic matter have been analysed for their carbon content, their absolute concentration and their stable carbon isotope ratios. Most organic subfractions from plants, or soil, are 13C-depleted by up to 9.4‰ relative to bulk organic matter, mainly as a result of their higher lipid content. Furthermore, soil organic constituents are...

1. Abundance and composition of periphyton and benthic macroinvertebrates were treated as potential nutrient response variables for 74 streams in montane Colorado. The streams ranged from unenriched to mildly enriched with nutrients (N, P). 2. The study showed no meaningful relationship between periphyton biomass accumulation and concentrations of total or dissolved forms of nitrogen or phospho...

In the microcanonical ensemble for string theory on AdSm × Sn, there is a phase transition between a black hole solution extended over the Sn and a solution localized on the Sn if the AdSm has the topology R2 × Sm−2. The phase transition will not appear if the AdSm has the topology R2 × Tm−2, that is, when the AdSm × Sn geometry is regarded as arising from the nearhorizon limit of a black m− 2 ...

We present observations of 13CO(1–0) in 17 Combined Array for Research in Millimeter Astronomy ATLAS3D early-type galaxies (ETGs), obtained simultaneously with 12CO(1–0) observations. The 13CO in six ETGs is sufficiently bright to create images. In these six sources, we do not detect any significant radial gradient in the 13CO/12CO ratio between the nucleus and the outlying molecular gas. Using...

We have compared the flowering response to vernalization, photoperiod, and far-red (FR) light of the Columbia (Col) and Landsberg erecfa (Ler) ecotypes of Arabidopsis into which the flowering-time locus FRIGIDA (FRI) has been introgressed with that of the wild types Col, Ler, and San Feliu-2 (Sf-2). In the early-flowering parenta1 ecotypes, Col and ler, a large decrease in flowering time in res...

Based upon down core variations in OrMn ratio in sediment and in micronodules, Mn content, organic carbon and abundance of micronodules in two box cores from high and low sedimentation regions of the Bay of Bengal, 0–20 and 0–40 cm levels were identified as ‘‘Mn oxidation zone’’ in the western and the eastern regions of the bay. Despite similarity in bottom water O and organic carbon contents o...

Eight genotypes of lentil (Lens culinaris Medik.) were tested for bioaccumulation and transport of arsenic (As) in a pot experiment under controlled growth condition. Along with control (no As was added), plants were grown for 60 d in pot soil spiked with 100 mg As kg, added as Sodium arsenate. Significant (P < 0.05) variations among eight genotypes were observed in bioaccumulation and transpor...

During the last two decades, quality had become a very important issue in many large organisations for both industrial and service sectors. They regard quality as a formidable weapon in addressing business competition and challenges both from local and global competitors. At present, small and medium enterprises (SMEs) had also joint the bandwagon in their effort to improve their products and s...
