Fish tolerance to organophosphate-induced oxidative stress is dependent on the glutathione metabolism and enhanced by N-acetylcysteine

2003

Abstract Dichlorvos (2,2-dichlorovinyl dimethyl phosphate, DDVP) is an organophosphorus (OP) insecticide and acaricide extensively used to treat external parasitic infections of farmed fish. In previous studies we have demonstrated the importance of the glutathione (GSH) metabolism in the resistance of the European eel ( Anguilla anguilla L.) to thiocarbamate herbicides. The present work studied the effects of the antioxidant and glutathione pro-drug N -acetyl- l -cysteine (NAC) on the survival of a natural population of A. anguilla exposed to a lethal concentration of dichlorvos, focusing on the glutathione metabolism and the enzyme activities of acetylcholinesterase (AChE) and caspase-3 a…

Precision luminosity measurements at LHCb

2014

Measuring cross-sections at the LHC requires the luminosity to be determined accurately at each centre-of-mass energy $\sqrt{s}$. In this paper results are reported from the luminosity calibrations carried out at the LHC interaction point 8 with the LHCb detector for $\sqrt{s}$ = 2.76, 7 and 8 TeV (proton-proton collisions) and for $\sqrt{s_{NN}}$ = 5 TeV (proton-lead collisions). Both the "van der Meer scan" and "beam-gas imaging" luminosity calibration methods were employed. It is observed that the beam density profile cannot always be described by a function that is factorizable in the two transverse coordinates. The introduction of a two-dimensional description of the beams improves sig…

Application of Chemical Cues in Arthropod Pest Management for Orchards and Vineyards

2013

This chapter reviews the literature on semiochemical-parasitoid systems in perennial crops. The first part of the chapter analyses the possible effects of pheromone-based tactics on parasitoid efficacy. In both orchards and vineyards, the most successful application of synthetic sex pheromones has been their use as mating disruptants. It also discusses the possibility of using parasitoid pheromones to directly affect parasitoid behaviour. The second part of the chapter summarizes research in orchards and vineyards that has tested whether synthetic chemical cues such as herbivore-induced plant volatiles (HIPVs) and host-associated volatiles (HAVs) can be used to manipulate parasitoid behavio…

Zanim został ministrem: o kontaktach Ryszarda Zakrzewskiego z wywiadem PRL

2017

After the Second World War Ryszard Zakrzewski (1913–1994) was a well-known exile political and social activist in Great Britain. In the late 1940s he became one of the leaders of the Polish Socialist Party in emigration. He was also active in the Polish Ex-Combatants’ Association and the Federation of Poles in Great Britain. In 1956, the intelligence of the Polish People’s Republic got interested in his person. Over the next few years Zakrzewski maintained contacts with intelligence officers, employed as diplomats at the Polish Embassy in London. Despite the fact that he was not formally recruited, he provided information about activities of certain political groups on emigration, especiall…

Massive Open Online Courses for IFRS Education: A Point of view of Spanish Accounting Educators

2016

Abstract This paper is based on a survey of 103 accounting educators from different universities of Spain on the use of MOOC, especially as regards teaching IFRS. The results show significant differences in three areas of opinion: i) the importance of the use of Internet and some Web tools for academic use; ii) general knowledge and perception of MOOCs; and iii) the opinions regarding the interest of MOOCs on IFRS. The overall opinion of educators is positive because, although the majority has never taught or participated in a MOOC, over 80% consider it useful in the learning process. Flexibility is considered the main advantage of MOOCs as well as its valuable potential for autonomous lear…

Un análisis empírico del impacto de la regulación contable en el mercado de auditoría

2017

El objetivo de la presente tesis se centra en el estudio de la estructura del mercado de la auditoría así como en analizar el impacto económico que la regulación contable ejerce sobre determinados elementos del mercado de auditoría (honorarios y rentabilidad de las firmas de auditoría). A partir de la publicación del Reglamento europeo 1606/2002 se requirió a los grupos cotizados que formulasen sus estados financieros consolidados desde el 1 de enero de 2005, conforme a las Normas Internacionales de Información Financiera o NIIF. En España, la adaptación de las NIIF al resto de empresas, no se llevó a cabo hasta la aprobación del Nuevo Plan General Contable (NPGC) y del plan para pequeñas y…

Septal complex of the telencephalon of lizards: III. Efferent connections and general discussion.

1998

The projections of the septum of the lizard Podarcis hispanica (Lacertidae) were studied by combining retrograde and anterograde neuroanatomical tracing. The results confirm the classification of septal nuclei into three main divisions. The nuclei composing the central septal division (anterior, lateral, medial, dorsolateral, and ventrolateral nuclei) displayed differential projections to the basal telencephalon, preoptic and anterior hypothalamus, lateral hypothalamic area, dorsal hypothalamus, mammillary complex, dorsomedial anterior thalamus, ventral tegmental area, interpeduncular nucleus, raphe nucleus, torus semicircularis pars laminaris, reptilian A8 nucleus/ substantia nigra and cen…

Intercurrent factors associated with the development of open-angle glaucoma in The European Glaucoma Prevention Study

2007

Purpose: To evaluate the intercurrent factors for the development of open-angle glaucoma (OAG) in ocular hypertensive patients who were enrolled in the European Glaucoma Prevention Study (EGPS). Design: Randomized, double masked, controlled clinical trial. Methods: setting: Multicenter. study population: A total of 1,077 patients fulfilled a series of inclusion criteria, including intraocular pressure (IOP) 22 to 29 mm Hg, normal and reliable visual fields (VFs) and normal optic disks. intervention: Treatment with dorzolamide or placebo. main outcome measures: Glaucoma-related VF or optic disk changes. Clinical data were collected every six months during a five-year follow-up. Proportional …

Updated single and dual crop coefficients for tree and vine fruit crops

2021

Abstract The present study reviews the research on the FAO56 crop coefficients of fruit trees and vines performed over the past twenty years. The main objective was to update information and extend tabulated single (K c ) and basal (K cb ) standard crop coefficients. The selection and analysis of the literature for this review have been done to consider only studies that adhere to FAO56 method, computing the reference ET with the FAO Penman–Monteith​ ET o equation and field measuring crop ET with proved accuracy. The crops considered refer to vine fruit crops, berries and hops, temperate climate evergreen fruit trees, temperate climate deciduous fruit trees and, tropical and subtropical fru…
