Diversity of rhizobia nodulating wild shrubs of Sicily and some neighbouring islands

2008

Abstract Legume shrubs have great potential for rehabilitation of semi-arid degraded soils in Mediterranean ecosystems as they establish mutualistic symbiosis with Nfxing rhizobia. Eighty-eight symbiotic rhizobia were isolated from seven wild legume shrubs native of Sicily (Southern Italy) and grouped in operational taxonomic units (OTU) by analysis of the ribosomal internal transcribed spacer (ITS) polymorphism. Partial sequencing of 16S rRNA gene of representative isolates of each OTU revealed that most Genisteae symbionts are related to Bradyrhizobium canariense, B. japonicum and B. elkanii. Teline monspessulana was the only Genistea nodulated by Mesorhizobium strains, and Anagyris foeti…

Genotypic characterization of Bradyrhizobium strains nodulating small Senegalese legumes by 16S-23S rRNA intergenic gene spacers and amplified fragme…

2000

ABSTRACT We examined the genotypic diversity of 64 Bradyrhizobium strains isolated from nodules from 27 native leguminous plant species in Senegal (West Africa) belonging to the genera Abrus , Alysicarpus , Bryaspis , Chamaecrista , Cassia , Crotalaria , Desmodium , Eriosema , Indigofera , Moghania , Rhynchosia , Sesbania , Tephrosia , and Zornia , which play an ecological role and have agronomic potential in arid regions. The strains were characterized by intergenic spacer (between 16S and 23S rRNA genes) PCR and restriction fragment length polymorphism (IGS PCR-RFLP) and amplified fragment length polymorphism (AFLP) fingerprinting analyses. Fifty-three reference strains of the different B…

Conservation of type III secretion system genes inBradyrhizobiumisolated from soybean

2006

International audience; The distribution of rhcRST genes encoding the type III secretion system (T3SS) in a collection of Bradyrhizobium strains was characterized by PCR and Southern blot hybridization. The polymorphism of the corresponding sequences amplified by PCR was characterized by RFLP and sequencing together with those available in the databank. Genomic group I is characterized by the presence of Bradyrhizobium elkanii strains and group II by the presence of B. japonicum and B. liaoningense strains. Highly conserved T3SS-like genes were detected by PCR in all Bradyrhizobium strains isolated from soybean belonging to genomic group II, and in none of the strains belonging to genomic g…

Overexpression and functional characterization of kinin receptors reveal subtype-specific phosphorylation.

1999

G protein-coupled receptors such as the receptors for bradykinin are present in low copy numbers in most natural cells. To overcome the problems associated with the analysis of these receptors at the protein level, we used highly efficient expression systems such as the baculovirus/insect cell system. However, the structural and functional statuses of recombinant receptors have often remained elusive. We have expressed the two types of human kinin receptors, B1 and B2, in Sf9 cells. Both receptors are found on the surface of infected cells where they display the same pharmacological profiles as their cognate receptors of native cells. The functional analysis of kinin receptors coupled to th…

On the finite element simulation of thermal phenomena in machining processes

2007

Machining processes are frequently investigated by numerical simulations. Usually 2D analyses are carried out in order to reduce CPU times, considering orthogonal cutting conditions. In this way, the computational time sharply reduces and many process variables may be calculated (i.e. forces, chip morphology, shear angle, contact length). On the other hand, the analysis of thermal aspects involved in machining, for instance the temperature distribution reached in tool, still represents an open problem. Finite element codes are able to simulate a very short process time that is not sufficient to reach steady state conditions. Several approaches have been proposed to overcome this problem: in…

O obrzędowym charakterze cyklu "Dziadów" Adama Mickiewicza raz jeszcze

2013

The publication presented in the review is an interesting and much-needed research proposal, which combines the discourse of a philologist, an ethnographer, and a cultural anthropologist. This approach is innovative in the literary studies research on this Polish master dramatist; it constitutes a valuable source not only for literary commentators of Mickiewicz’s series but also for Belorussian folklore scholars, or for those investigating the merging of Polish and Belorussian culture. It makes us realize that, among others, by means of his drama, the poet introduced the Belorussian rite of dziady – a pagan festival in honour of ancestral spirits – into Polish culture. The rite is, for the …

O przemianach obrzędowości Świąt Wielkanocnych w Polsce (na przykładzie święcenia potraw)

2019

Przedmiotem refleksji są wybrane aspekty dotyczące przeobrażeń obrzędowości Świąt Wielkanocnych w Polsce. W artykule skupiono uwagę przede wszystkim na tradycji święcenia pokarmów w Wielką Sobotę, omówiono dawne i współczesne praktyki zwyczajowe z nią związane. Podstawą opracowań jest dostępna literatura etnograficzna, pilotażowe badania terenowe prowadzone przez autorkę w różnych częściach Polski, w tym głównie w województwach śląskim, opolskim i łódzkim oraz materiały internetowe.

World Interest Rates and Inequality: Insight from the Galor - Zeira Model

2018

In this paper, we study the relationship between changes in the world interest rate and within-country inequality during the 1985–2005 period in which the world interest rate sharply declined. In line with the predictions of the seminal model of Galor and Zeira [Income distribution and macroeconomics. Review of Economic Studies 60, 35–52], the analysis suggests that the decrease in the world interest rate is associated with a decrease in inequality in poor countries and an increase in inequality in rich ones.

Sustainable Energy Supply in Vietnam

2020

The steep growth of electricity demand in Vietnam (11% per year on average since 2006) calls for a deep rethinking of the Vietnamese electrical power system. Its topological structure indeed may not be well suited for a deep penetration of renewable energy sources and a predictable increase of reactive industrial loads. The Vietnamese power system is described and a few analytical methods are considered for its study both in steady state and in dynamic conditions in different scenarios. The power system simulation software Neplan is used for the implementation of the system’s model and the performing of the dynamic analysis.
