Effect of bacterial inoculation, plant genotype and developmental stage on root-associated and endophytic bacterial communities in potato (Solanum tuberosum)
No full textBeneficial bacteria interact with plants by colonizing the rhizosphere and roots followed by further spread through the inner tissues, resulting in endophytic colonization. The major factors contributing to these interactions are not always well understood for most bacterial and plant species. It is believed that specific bacterial functions are required for plant colonization, but also from the plant side specific features are needed, such as plant genotype (cultivar) and developmental stage. Via multivariate analysis we present a quantification of the roles of these components on the composition of root-associated and endophytic bacterial communities in potato plants, by weighing the effects of bacterial inoculation, plant genotype and developmental stage. Spontaneous rifampicin resistant mutants of two bacterial endophytes, Paenibacillus sp. strain E119 and Methylobacterium mesophilicum strain SR1.6/6, were introduced into potato plants of three different cultivars (Eersteling, Robijn and Karnico). Densities of both strains in, or attached to potato plants were measured by selective plating, while the effects of bacterial inoculation, plant genotype and developmental stage on the composition of bacterial, Alphaproteobacterial and Paenibacillus species were determined by PCR-denaturing gradient gel-electrophoresis (DGGE). Multivariate analyses revealed that the composition of bacterial communities was mainly driven by cultivar type and plant developmental stage, while Alphaproteobacterial and Paenibacillus communities were mainly influenced by bacterial inoculation. These results are important for better understanding the effects of bacterial inoculations to plants and their possible effects on the indigenous bacterial communities in relation with other plant factors such as genotype and growth stage
Comments on Some Critical Remarks on the Paper »Fixed Charge Double Layer Potential Equations - a Derivation« by J. Th. G. Overbeek
No full textProfessor Overbeek in his paper »Some Critical Remarks on the Paper
»Fixed Charge Double Layer Potential Equations - a Derivation« by M.
Mirnik published in Croat. Chem. Acta 42 (1970) 505, claimed that the criticized paper contains arbitrary assumptions and internal inconsistencies. By careful reading of the criticized paper objective unbiassed readers would
probably come to the conclusion that Professor Overbeek's claims do not hold. However, in order to demonstrate and prove that Professor Overbeek's criticism is unjustified the following comments are given to it

Un démographe prémalthusien au XVIIIe siècle : Giammaria Ortes
No full textLe XVIIIe siècle est sans doute celui où les questions de population ont tenu le plus de place et pendant lequel les idées ont le plus évolué, du mercantilisme typiquement populationniste à la doctrine pessimiste de Malthus, en passant par la physiocratie de Quesnay, très nuancée en matière d'accroissement de population, le libéralisme d'Adam Smith et bien d'autres. A plusieurs reprises, la revue « Population » a publié des articles surdivers doctrinaires. D'autre part, trois volumes ont été consacrés à de grands noms et un quatrième, en 1970, sera consacré à Süssmilch. Enfin un ouvrage a porté sur les doctrines en Pologne. C'est une figure curieuse, le vénitien Ortes, que présente, dans cet article, M. Hans Overbeek, économiste hollandais qui enseigne à l'Université de Columbia britannique à Vancouver.Overbeek Hans.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
