the low pO 2 treatment in both species. Immunogold labelling showed that the MAC265 antigen was localThe pasture legumes Lotus uliginosus (Schk.) and ized primarily within intercellular spaces within nodule Lotus corniculatus (L.), known to differ in their tolercortices from both Lotus species. A marked decrease ance to flooding, were inoculated with Rhizobium loti in deposition of the MAC265 a...

The bicistronic groESL operon, encoding the Hsp60 and Hsp10 chaperonins, was cloned into an integrative expression vector, pFPN, and incorporated at an innocuous site in the Anabaena sp. strain PCC7120 genome. In the recombinant Anabaena strain, the additional groESL operon was expressed from a strong cyanobacterial P(psbA1) promoter without hampering the stress-responsive expression of the nat...

This paper contrasts the natural and anthropogenic controls on the conversion of unreactive N2 to more reactive forms of nitrogen (Nr). A variety of data sets are used to construct global N budgets for 1860 and the early 1990s and to make projections for the global N budget in 2050. Regional N budgets for Asia, North America, and other major regions for the early 1990s, as well as the marine N ...

New C,C-linked bipyrazole 1,1’-di(4-aminophenyl)-5,5’-diisopropyl-3,3’-bipyrazole (2) has been synthesized and characterized. Theoretical calculations have been carried out on target 2 and literature 1 C,C-linked bipyrazoles to compare with reported results. All calculations were carried out with the AM1 level of theory using the GAUSSIAN 03. The nature of substituent attached to the pyrazolic ...

Effects of simulated nitrogen (N) deposition on soil net nitrogen mineralization (NNM) were examined in situ during two growing seasons, using the resin-core technique in the semiarid meadow steppe in Inner Mongolia, China. The aim of this study is to clarify the effect of N levels (0, 10, and 20 kg N ha-1yr-1) and forms (NH4+ and NO3-) on soil mineral N and NNM. Our results showed that N level...

Photosynthetic data collected from Pisum sativum L. and Phaseolus vulgaris L. plants at different stages of development were related to symbiotic N(2) fixation in the root nodules. The net carbon exchange rate of each leaf varied directly with carboxylation efficiency and inversely with the CO(2) compensation point. Net carbon exchange of the lowest leaves reputed to supply fixed carbon to root...

An effect of rolling temperature on the mechanical properties and microstructural evolution of an Al-Mg-Si alloy was studied. The material was rolled up to a true strain of ∼0.7 at three different temperatures viz; room temperature, liquid propanol and liquid nitrogen. The liquid nitrogen rolled sample exhibited superior properties with a yield and tensile strength of 332 MPa and 364 MPa, respe...

I. Published results have been used to study the relationships between nitrogen retention (NR), body-weight (W) and N intake in the pig. 2. The general decrease in maximal NR (g/d per kg W0.75) with increasing W (kg) was curvilinear for values of W from 1-5 to 45: NR = 3.324--0.098 W + 0.001 W2; and rectilinear for values of W from 45 to 165: NR = 1.252--0.006 W. Values for protein requirements...

in order to study the effect of irrigation and nitrogen fertilizer levels on yield of basil, an experiment was conducted as split plot based on randomized complete block design with three replications in birjand (moud region) in 2010. main plot factor was two irrigation levels (7 and 14 days interval) and nitrogen fertilizer (as urea) was considered as sub plot factor in four levels (0, 50, 100...

Pseudomonas putida CA-3 is capable of converting the aromatic hydrocarbon styrene, its metabolite phenylacetic acid, and glucose into polyhydroxyalkanoate (PHA) when a limiting concentration of nitrogen (as sodium ammonium phosphate) is supplied to the growth medium. PHA accumulation occurs to a low level when the nitrogen concentration drops below 26.8 mg/liter and increases rapidly once the n...
