Sensing of O 2 and nitrate by bacteria: alternative strategies for transcriptional regulation of nitrate respiration by O 2 and nitrate
2020
Many bacteria are able to use O2 and nitrate as alternative electron acceptors for respiration. Strategies for regulation in response to O2 and nitrate can vary considerably. In the paradigmatic system of E. coli (and γ-proteobacteria), regulation by O2 and nitrate is established by the O2 -sensor FNR and the two-component system NarX-NarL (for nitrate regulation). Expression of narGHJI is regulated by the binding of FNR and NarL to the promoter. A similar strategy by individual regulation in response to O2 and nitrate is verified in many genera by the use of various types of regulators. Otherwise, in the soil bacteria Bacillus subtilis (Firmicutes) and Streptomyces (Actinobacteria), nitrat…
Antioxidant activity and phenolic composition in pomegranate (Punica granatumL.) genotypes from south Italy by UHPLC-Orbitrap-MS approach
2018
Background: Pomegranate fruits are a rich source of polyphenols with numerous health-promoting effects. Pomegranate juices of five genotypes ('Mollar', 'Kingdom', 'Dente di Cavallo', and two old populations 'Francofonte' and 'Santa Tecla') were evaluated regarding anthocyanin and non-anthocyanin phenolic contents using ultrahigh performance liquid chromatography (UHPLC)-Orbitrap-mass spectrometry (MS). Moreover, total antioxidant activity (TAA) was evaluated using a 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) assay.; Results: Twenty-three phenolic compounds were identified. Cyanidin-3,5-O-diglucoside and pelargonidin-3,5-O-diglucoside were the most represent…
Cadmium, Copper and Tributyltin effects on fertilization of Paracentrotus lividus (Echinodermata)
2009
Marine environments are continuously being threatened by a large number of xenobi- otics from anthropogenic sources. The effect of chemical pollution on living organisms are numerous and may impair reproductive success of adults species of marine invertebrate and vertebrate through effects on gamete quality. Echinoderms are characterized by external fertilizzation and gametes, free of any type of protection, may be in contact with toxic substances so the reproductive success depends largely on the environment conditions. The purpose of this work is to assess the effects on the in vitro fertiliza- tion of exposure of sea urchin Paracentrotus lividus gametes to xenobiotic substances as CuSO4,…
Subtitling and dubbing as teaching resources for learning English as a foreign language using Clipflair software
2020
[EN] The research validity of using clips as audiovisual material to teach a foreign language has been demonstrated by many scholars. At the same time, the combination of this material with two modalities of audiovisual translation (AVT) - subtitling and dubbing- is worth exploring. The aim of this study is to present the effectiveness of subtitling and dubbing activities as tools for teaching English as a foreign language. In order to do so, a number of participants from the University of Valencia (Spain) whose level of English was B2/B2+ were engaged in a combination of subtitling and dubbing activities. I devised a series of tasks based on a two-minute subtitled video-clip, designed to i…
Predicting response to transdiagnostic iCBT for emotional disorders from patient and therapist involvement
2021
Background Transdiagnostic iCBT has been shown to be effective for the treatment of emotional disorders. Less is known about the optimal level of therapist and patient involvement in these interventions. Specific characteristics of Internet-delivered interventions include treatment adherence (e.g., amount of review of the materials) and guidance (e.g., amount of therapist support). Exploring the importance of these elements in treatment outcome may help to maximize the efficiency of Internet-delivered psychological interventions. Aim In this study, we aimed to analyze the relationship between patient and therapist involvement (i.e., platform usage and amount of therapist guidance) in a samp…
The Case for Contingent Convertible Debt for Sovereigns
2015
We make the case for sovereigns to issue contingent convertible bonds as a means to forestall debt crises. These instruments contractually stipulate payment standstill, contingent on a sovereign’s credit default swap spread breaching a distress threshold. This is a financial innovation solution to the lack of sovereign debt restructuring mechanisms, limiting ex ante the likelihood of debt crises and imposing ex post risk sharing between creditors and the debtor. The new instruments are contingent contracts addressing neglected risks in sovereign debt. Building on literature for contingent convertible debt for banks we address the design of sovereign contingent debt, including market discipl…
Sustainable Growth Rate: An Analysis Regarding the Most Traded Companies on the Bucharest Stock Exchange
2018
The concept of sustainable growth rate was originally developed by Robert C. Higgins. In the case of companies with given stable financial policies, it is considered to be the link between growth-return rate combinations that gives a balanced growth line. This indicates the possibilities for a company to grow without generating deficits or cash surpluses. Increased sales require more assets, which can be financed by new debt, external equity, and internal equity through retained earnings. The sustainable growth rate is the maximum rate at which company sales can increase without decreasing its financial resources. The aim of this paper is to determine if the last year most traded companies …
COVID-19 Crisis - A Test for European Union’s Solidarity
2020
Abstract The crises the European Union has gone through over time have called into question the Union’s legitimacy and efficiency. The 2008-2009 financial crisis, the European debt crisis, the migration crisis and Brexit, have all tested the solidarity between member states. The COVID-19 pandemic is without a doubt the most drastic crisis in the EU’s history, with very severe socioeconomic consequences. The EU leaders were strongly criticized for not reacting quickly and efficiently enough to mitigate the impact of the virus, reduce suffering, and ward off the economic crisis. In this context, the questions that arise are: Is the Union a modern-day Titanic? Will it sink or it will sustain i…
The Value Relevance of Operating Lease Liabilities: Economic Effects of IFRS 16
2018
The new IASB and FASB models for leases aim to improve the quality of financial reporting. To this end, both standard setters impose the recognition of assets and liabilities for operating leases. Meanwhile, preparers have been strongly lobbying against these changes, as in their view the new treatment will lead to negative economic consequences. We undertake a value‐relevance study to examine whether as‐if capitalised operating leases are priced by market users in a relatively unexplored setting. We consider Spanish listed firms, and employ hand‐collected data on operating leases disclosed in the notes to the financial statements to constructively capitalise the assets and liabilities. Our…
Simplified restructuring proceedings in Poland as an example of anti – crisis regulation due to the COVID-19 pandemic
2020
Summary The study discusses new legislative anti – crisis solutions adopted in Poland in connection with the COVID – 19 pandemic. The Polish legislator decided to introduce the so-called simplified restructuring procedure. This happened in the face of the expectations of both the jurisprudence of law and practice. On the one hand, the simplified restructuring procedure (the fifth independent type of restructuring procedure for an entrepreneur in Poland) allows for a quick, cheap and simplified conclusion of an arrangement with creditors outside the court, then approved by the court. On the other hand, the opening of such proceedings gives the debtor protection against enforcement at the cre…
