Corporate Networks and business influence in Panama, Costa Rica, and El Salvador.

2021

Objective/Context: This paper explores the relationship between corporate networks and business influence to figure out the conditions of state capture. Methodology: We analyze corporate networks through interlocking directorates in three Central American countries - Panama, Costa Rica, and El Salvador - using network analysis, and we pinpoint the relationship between the structure of the corporate network and two corporate political actions: contributions to presidential campaigns and revolving doors. Conclusions: Results show corporate networks were fragmented in the three Central American countries, except for a well-connected business cluster in Panama. The organization of business elit…

Reading the Transformations of an Urban Edge: From Liberty Era Palermo to the City of Today

2019

To honour the battle of 27 May 1860, in 1910 the Palermo City Government decided to realise a commemorative monument. A position at the centre of a large circular plaza was of have afforded the monument a greater solemnity. The commission for the Monument was awarded to Ernesto Basile. In 1927 the City Government decided to dedicate the monument to the Fallen and asked Basile to complete the monument adding an architectural backdrop. The first version of the new project was a fence that enveloped the entire square and the ring road, interrupted only by entrances near the streets flowing into the square, and dividing it into four sectors. The final design instead called for the realisation o…

Impacts of piscicide-induced fish removal on resource use and trophic diversity of lake invertebrates

2022

Chemical eradication of non-native species has become a widely used method to mitigate the potential negative im- pacts of altered competitive or predatory dynamics on biodiversity and natural ecosystem processes. However, the re- sponses of non-target species can vary from rapid full recovery to delayed or absent recolonization, and little is known about the potential shifts in resource use and trophic diversity of native species following chemical treatments. We used a before-after-control-impact approach to study the effects of rotenone piscicide treatment on abundance and tro- phic niche of benthic invertebrates in three untreated and three treated lakes in central Norway, the latter gr…

Errors d?edició : dels manuscrits als diccionaris. Exemples de textos mèdics medievals (Hipòcrates, Arnau de Vilanova, Bernat de Gordon, misser Joan)

2017

The commonly used Catalan lexicons (DCVB, DECLC, the vocabulary of Lluis Faraudo de Saint-Germain) collect words and give them meaning from ancient editions of texts. Lexicographers’ performance had its own logic: they used the documentary sources they had at their disposal when they set up to write their works. The advances in philological research (new critical editions, new sources of information) allow us to refine results and detect errors that occurred in old editions and went into dictionaries. Wrong lexemes were included, as well as incorrect or insufficient definitions. This article offers examples of it, out of four medical works. On the one hand, the Catalan translations of the R…

Depth Enhancement by Fusion for Passive and Active Sensing

2012

This paper presents a general refinement procedure that enhances any given depth map obtained by passive or active sensing. Given a depth map, either estimated by triangulation methods or directly provided by the sensing system, and its corresponding 2-D image, we correct the depth values by separately treating regions with undesired effects such as empty holes, texture copying or edge blurring due to homogeneous regions, occlusions, and shadowing. In this work, we use recent depth enhancement filters intended for Time-of-Flight cameras, and adapt them to alternative depth sensing modalities, both active using an RGB-D camera and passive using a dense stereo camera. To that end, we propose …

Inbreeding does not alter the response to an experimental heat wave in a freshwater snail

2019

Global climate change affects natural populations of many species by increasing the average temperature and the frequency of extreme weather events (e.g. summer heat waves). The ability of organisms to cope with these environmental changes can, however, depend on their genetic properties. For instance, genetic load owing to inbreeding could alter organisms’ responses to climate change-mediated environmental changes but such effects are often overlooked. We investigated the effects of an experimental heat wave (25°C versus 15°C) on life history (reproduction, size) and constitutive immune defence traits (phenoloxidase-like and antibacterial activity of haemolymph) in relation to inbreeding b…

Fumarate respiration of Wolinella succinogenes: enzymology, energetics and coupling mechanism.

2002

Wolinella succinogenes performs oxidative phosphorylation with fumarate instead of O2 as terminal electron acceptor and H2 or formate as electron donors. Fumarate reduction by these donors ('fumarate respiration') is catalyzed by an electron transport chain in the bacterial membrane, and is coupled to the generation of an electrochemical proton potential (Deltap) across the bacterial membrane. The experimental evidence concerning the electron transport and its coupling to Deltap generation is reviewed in this article. The electron transport chain consists of fumarate reductase, menaquinone (MK) and either hydrogenase or formate dehydrogenase. Measurements indicate that the Deltap is generat…

Candida albicans mycelial wall structure: supramolecular complexes released by zymolyase, chitinase and beta-mercaptoethanol.

1991

Different techniques released from the wall of Candida albicans mycelial cells high molecular weight mannoprotein materials with different levels of complexity. SDS solubilized among others one protein of 180 kDa which reacted with a monoclonal antibody (MAb) specific of a O-glycosylated protein secreted by regenerating mycelial protoplasts [Elorza et al. (1989) Biochem Biophys Res Commun 162:1118-1125]. Zymolyase, chitinase and beta-mercaptoethanol, released different types of high molecular highly polydisperse mannoprotein materials (greater than 180 kDa) that also reacted with the same MAb. These materials had N-glycosidically linked sugar chains, in addition to the O-glycosidically bond…

Use of the preliminary Jedlice Reservoir for water protection in the Turawa Reservoir on the Mała Panew River

2009

Abstract Physico-chemical variables of water quality and benthic community structure were assessed in order to evaluate the need for reinstating the use of the preliminary Jedlice Reservoir. The waters of the Mała Panew River carry a significant load of nutrient compounds, particularly nitrates and phosphates. Deteriorating water quality results in permanent algal blooms and changes in the macrofauna structure. It was confirmed that the use of a preliminary reservoir could contribute to the protection of the Turawa Dam Reservoir against pollutants transported by the waters of the Mała Panew River.
