Sub-critical filtration conditions of commercial hollow-fibre membranes in a submerged anaerobic MBR (HF-SAnMBR) system: The effect of gas sparging i…

2012

A submerged anaerobic MBR demonstration plant with two commercial hollow-fibre ultrafiltration systems (PURON®, Koch Membrane Systems, PUR-PSH31) was operated using municipal wastewater at high levels of mixed liquor total solids (MLTS) (above 22gL -1). A modified flux-step method was applied to assess the critical flux (J C) at different gas sparging intensities. The results showed a linear dependency between J C and the specific gas demand per unit of membrane area (SGD m). J C ranged from 12 to 19LMH at SGD m values of between 0.17 and 0.5Nm 3h -1m -2, which are quite low in comparison to aerobic MBR. Long-term trials showed that the membranes operated steadily at fluxes close to the est…

Avantages comparatifs et dynamiques de spécialisation : le cas des pays africains.

2021

In this thesis we analyze the mechanisms linking trade openness and industrialization patterns. We are particularly interested in developing countries, especially those belonging to the African continent, because of their particular form of production specialization— essentially based on agricultural and mining products. Our goal is to better understand the evolution of these forms of specialization in order to identify possible paths of industrial development. Chapter 1 provides a comprehensive overview of the literature on the theoretical determinants of international specialization and pays particular attention to theories emphasizing a dynamic view of comparative advantage. This chapter…

The effectiveness of hypnosis for pain relief: A systematic review and meta-analysis of 85 controlled experimental trials.

2019

The current meta-analysis aimed to quantify the effectiveness of hypnosis for reducing pain and identify factors that influence efficacy. Six major databases were systematically searched for trials comparing hypnotic inductions with no-intervention control conditions on pain ratings, threshold and tolerance using experimentally-evoked pain models in healthy participants. Eighty-five eligible studies (primarily crossover trials) were identified, consisting of 3632 participants (hypnosis n = 2892, control n = 2646). Random effects meta-analysis found analgesic effects of hypnosis for all pain outcomes (g = 0.54-0.76, p’s<.001). Efficacy was strongly influenced by hypnotic suggestibility and u…

Comparative studies of water governance: a systematic review

2018

[EN] Governance is key to tackling water challenges and transforming water management under the increasing pressures of competing water uses and climate change. Diverse water governance regimes have evolved in different countries and regions to regulate the development and management of water resources and the provision of water services. Scholars and policy analysts have been comparing these water governance regimes to analyze elements and processes, to assess performance, or to draw lessons. Although the number of such studies has increased since the 1980s, no comprehensive synthesis exists. We present such a synthesis by conducting a systematic review of the emerging field of comparative…

Acetic acid compared with i-scan imaging for detecting Barrett's esophagus: a randomized, comparative trial.

2013

Background Traditional surveillance in patients with Barrett's esophagus (BE) has relied on random biopsies. Targeted biopsies that use advanced imaging modalities may significantly improve detection of specialized columnar epithelium (SCE). Objective We compared the efficacy of targeted biopsies that used i -scan or acetic acid to random biopsies in the detection of SCE. Design Patients with visible columnar lined epithelium or known BE were randomized at a 1:1 ratio to undergo acetic acid application or i -scan with targeted biopsies. Setting Targeted biopsies were performed based on surface architecture according to the Guelrud classification followed by 4-quadrant biopsies. Patients A t…

Lessons in Immunity: From Single-cell Organisms to Mammals

2016

Lessons in Immunity: From Single-cell Organisms to Mammals stems from the activity of the Italian Association of Developmental and Comparative Immunobiology (IADCI), represented by the editors. This book is presented as a series of short overviews that report on the current state of various relevant fields of immunobiology from an evolutionary perspective. The overviews are written by authors directly involved in the research, and most are members of the IADCI or have otherwise been involved in the related research for their respective overview. This publication offers scientists and teachers an easy and updated reference tool. Provides simple and updated reviews on the immunobiology of a w…

¿What Can We Learn from Educational Systems of Chile, Spain and Finland in the Framework of Salamanca Statement?

2019

Resumen: El presente artículo compara los sistemas de Educación Especial de Chile, España y Finlandia, desde la perspectiva de la Declaración de Salamanca para las Necesidades Educativas Especiales (NEE). Tanto el contexto general de sus sistemas educativos como su orientación epistemológica respecto de la Educación Especial, los marcos regulatorios de cada sistema, los procedimientos de detección y derivación de niños con nee, y la estructura de los servicios de atención a la diversidad, dialogan de manera particular con los compromisos adquiridos en 1994. Se muestran las principales diferencias entre los sistemas, destacando la gran variabilidad respecto de la definición de nee y sus estr…

THE BETWEEN-COUNTRY INEQUALITY: DOES IT HINDER THE COMPETITIVENESS?

2012

Nowadays the competitiveness is the significant premise to enhance the inhabitants well being. From this perspective on competitiveness has been given great attention in the literature and competitiveness hindrances have been studied as well. However the link between inequality and competitiveness is less studied, particular in case of the European Union. Thereby the author attempts to clarify the role of the between-country income inequality in hindering the competitiveness.The data analysis shows that lower income countries have less ability towards strengthening the nation economy competitiveness thereby reducing overall European Union competitiveness level. Obviously the country's compe…

Phylogeography and genetic variation of Triatoma dimidiata, the main Chagas disease vector in Central America, and its position within the genus Tria…

2008

Background Among Chagas disease triatomine vectors, the largest genus, Triatoma, includes species of high public health interest. Triatoma dimidiata, the main vector throughout Central America and up to Ecuador, presents extensive phenotypic, genotypic, and behavioral diversity in sylvatic, peridomestic and domestic habitats, and non-domiciliated populations acting as reinfestation sources. DNA sequence analyses, phylogenetic reconstruction methods, and genetic variation approaches are combined to investigate the haplotype profiling, genetic polymorphism, phylogeography, and evolutionary trends of T. dimidiata and its closest relatives within Triatoma. This is the largest interpopulational …
