Comprehensive assessment of the microalgae-nitrifying bacteria competition in microalgae-based wastewater treatment systems: Relevant factors, evalua…

2022

[EN] Due to their capacity to assimilate carbon dioxide and nutrients, microalgae-based cultivation systems have emerged as a green solution for intensive wastewater treatment. However, when large concentrations of ammonium are present the competition between microalgae and ammonium-oxidising bacteria plays a significant role. Microalgae use ammonium to synthesise proteins, photosynthetic pigments and nucleic acids, while ammonium-oxidising bacteria use it as a source of electrons and oxidise it to nitrite.Several authors have studied the isolated factors that influence microalgae-nitrifying bacteria competition, although a comprehensive analysis of this interesting topic is still lacking. …

Wastewater nutrient removal in a mixed microalgae-bacteria culture: effect of light and temperature on the microalgae-bacteria competition.

2018

[EN] The aim of this study was to evaluate the effect of light intensity and temperature on nutrient removal and biomass productivity in a microalgae¿bacteria culture and their effects on the microalgae¿bacteria competition. Three experiments were carried out at constant temperature and various light intensities: 40, 85 and 125¿µE¿m¿2¿s¿1. Other two experiments were carried out at variable temperatures: 23¿±¿2°C and 28¿±¿2°C at light intensity of 85 and 125¿µE¿m¿2¿s¿1, respectively. The photobioreactor was fed by the effluent from an anaerobic membrane bioreactor. High nitrogen and phosphorus removal efficiencies (about 99%) were achieved under the following operating conditions: 85¿125¿µE¿…

The Institutionalists’ Reaction to Chamberlin’s 'Theory of Monopolistic Competition

2009

Edwin Chamberlin's The Theory of Monopolistic competition is often described as containing omportant traces of institutionalist influence. This is also confimred by Chamberlin himself who, repeadetly, referred to the work of Veblen, and John Maurice Clark among his inspirational sources. The aim of this paper is to analyse the institutionalist rection to the publication of the Theory of Monopolistic Competition. What will be argued is that the institutionalist response to Chamberlin was a mixed one, and involved some substantial criticisms of his analysis of market structures both on methodological and theoretical grounds. The paper is organized as follows. The first section presents a sket…

Male dominance and immunocompetence in a field cricket

2004

Female preference for dominant males has been found in many species, and it is generally thought that winners of male-male competition are of superior quality. Success in contests probably depends on male condition and overall health. Thus, females could avoid infection and gain genetic benefits in terms of more viable offspring by mating with dominant males. In the present study, we tested whether dominant males of the Mediterranean field cricket, Gryllus bimaculatus, had higher immunocompetence than did their subordinates in experimental trials. We found that dominant males had better immune defense, as indicated by significantly higher encapsulation rate and lytic activity, than did subo…

The impact of globalization on regional development and competitiveness: cases of selected regions

2019

International audience; The objective of this study is to conduct an analysis of regional development and competitiveness in the EU and Latvia under current conditions of economic globalization. This paper makes an attempt to evaluate a theory of regional development and regional competitiveness concept in relation to regional competitiveness in the light of current global economic changes. The authors emphasise that the regional development is based on competitive advantages, which has been a subject of fundamental research by Michal Porter and that serves as a basis for the current scientific methodology to assess competitiveness of regions and countries. The authors support a view of man…

Do shippers’ characteristics influence port choice criteria? Capturing heterogeneity by using latent class models

2022

Abstract This paper focuses on the study of Spanish ceramic tile exporters' port choice criteria, an industry that is characterized by a low unit value index. Thus, transport costs highly influence the competitiveness of their products in international markets, representing a relatively high percentage of the value of the shipment. It is therefore critical for this type of industry to have access to efficient door-to-door maritime chains. Determinants of port choice are analysed through a latent class model allowing to link class membership to specific characteristics of the shippers and their shipments such as the size of the company, the value of the shipment, the destination market and t…

Desarrolo, cultura e identidad en América Latina

2008

The author understands culture as more than a result of economic development; he argues that development, itself, is both a fact and a cultural product, based on his wide range concept of culture. According to the text, approaches willing to reduce definitions of development to its economic, social, or any other restrict aspect, only misunderstand the real concept and engender serious mistakes on Government’s action. Moreover, the text states that far from population explosion and absence of resources, problems of social injustice, poverty, social exclusion, disrespect of human rights and aggressions on the environment are basically consequences of the absence of universal ethical values, w…

Extensive gene flow blurs species boundaries amongVeronica barrelieri, V. orchideaandV. spicata(Plantaginaceae) in southeastern Europe

2011

Little is known about the contribution of interspecific hybridization, a frequent phenomenon in plants, to the high plant diversity in southeastern Europe, one of the continent's diversity hot spots. A good system to study the relevance of hybridization for biodiversity in this region is Veronica subg. Pseudolysimachium sect. Pseudolysimachion (Plantaginaceae). Depending on the presumed frequency of hybridization, existing taxonomic concepts in this group range from distinguishing only morphological races without explicit taxonomic status to recognizing several species each with a series of intraspecific taxa. Using genetic (plastid sequences and AFLP fingerprints), ploidy-level and morphom…
