Molecular tools to assess the diversity and density of denitrifying bacteria in their habitats

2007

Publisher Summary This chapter describes the molecular tools to assess the diversity and density of denitrifying bacteria in their habitats. Genome sequencing and metagenomic projects might even provide new denitrification gene sequences, which could aid in designing more broad range primers. Most information is obtained by cloning and sequencing the polymerase chain reaction (PCR) amplicons, but a more rapid analysis is achieved using fingerprinting techniques. As all PCR-based analyses, the fingerprinting techniques are subjected to well-known biases introduced by, e.g., DNA extraction procedures, primer selection, and PCR conditions. For denitrifiers, the PCR-RFLP (restriction fragment l…

Natural resources, electrification and economic growth from the end of the nineteenth century until World War II

2005

RESUMENLas repercusiones de la nueva rúente de energía, electricidad, en el crecimiento económico de una muestra de países –Estados Unidos, Reino Unido, Francia, Italia, España y Canadá- caracterizados por sus diferentes dotaciones de recursos carboníferos es el principal objetivo de este artículo. La nueva energía, entre otras ventajas, redujo la dependencia de los recursos naturales de carbón al poder generarse a partir de diferentes energías primarias: agua o carbón. Con el fin de valorar la importancia de esta reducción de la dependencia del carbón, se presenta una base de datos de los recursos energéticos para los seis países, se muestra que los precios relativos de la electricidad fre…

Does plant growth phase determine the response of plants and soil organisms to defoliation?

2005

Abstract To test a hypothesis that the effects of defoliation on plant ecophysiology and soil organisms depend on the timing of defoliation within a growing season, we established a greenhouse experiment using replicated grassland microcosms. Each microcosms was composed of three plant species, Trifolium repens , Plantago lanceolata and Phleum pratense , growing in grassland soil with a diverse soil community. The experiment consisted of two treatment factors—defoliation and plant growth phase (PGP)—in a fully factorial design. Defoliation had two categories, i.e. no trimming or trimming a total of four times at 2 week intervals. The PGP treatment had four categories, i.e. 1, 3, 7 or 13 wee…

Reduction of [(C 5 Me 5 ) 2 Mo 2 O 5 ] and [(C 5 Me 5 ) 2 Mo 2 O 4 ] in Methanol/Water/Trifluoroacetate Solutions Investigated by Combined On‐Line El…

2003

Complexes [Cp*2Mo2O5 ]( Cp* =η 5 -C5Me5) and [Cp*2Mo2O4] were investigated by combined on-line electrochemical (EC) reduction and electrospray-ionization mass spectrometry (ESI-MS) techniques in a trifluoroacetic acid buffered water/ methanol solution. The reduction products at the larger negative potentials are identical for both compounds. The studies reveal the existence of a wide range of previously unknown di- and trinuclear Mo V ,M o IV ,M o III , and mixed-val

Effect of the industrial wastes purification system on the productivity of the yeast factory Lesaffre in Wolczyn

2014

The purpose of this work is to present that rearrangement of the industrial wastes purification system may cause the growth of the productivity. The analysis presented deals with the yeast factory Lesaffre in Wolczyn (Poland). Most of the industrial wastes (JW) produced there are utilized in agricultural fields (AF) but part of them is pre-treated in an evaporator battery (EB). The basic parameter determining amount of the JW to be utilized in the AF is nitrogen concentration for this element in excess can lead to destruction of plants. At present only the JW coming out from the first two separators are directed to the EB in the factory. In order to increase the yeast productivity of the fa…

Charles LeGeyt Fortescue and the method of symmetrical components

2002

The author gives a brief review of the life and work of Charles LeGeyt Fortescue with particular reference to his 1918 paper on the "Method of Symmetrical Co-Ordinates Applied to the Solution of Polyphase Networks" which grew out of his investigations of problems related to railway electrification, which began in 1913. As a postlude to the author's article, the paper presents Fortescue's own writing on the topic of symmetrical components, which he included in a document he produced on 8 October 1934, titled "High Points in My Career".
