The waves of enterprises bankruptcy and the factors that determine them: the case of Latvia and Lithuania
2018
International audience; Bankruptcy of enterprises is macroeconomic issue and a phenomenon of a dynamic and competitive market economy. It results in a lot of negative effects not only for the enterprise and its employees but also for other enterprises and institutions, as well as the state and society. The aim of the article is to carry out the analysis of bankruptcy of Latvian and Lithuanian enterprises. No such study has been carried out so far. Article analyses the dynamics of Latvian and Lithuanian enterprise bankruptcy, which manifest themselves in larger waves in certain periods and the factors that influence them. From 1993-when the bankruptcy of enterprises was started to be officia…
La Seconda Vita dell'Ambiente Costruito
2021
Il contributo inquadra i saggi, gli studi, le ricerche e progetti pubblicati sul numero 9 di AGATHÓN su ‘La Seconda Vita dell’Ambiente Costruito’, tema di interesse per il mondo accademico, delle professioni e dell’industria. Cambiamenti climatici, eccessivo consumo di suolo e di risorse non rinnovabili, produzione sempre crescente di rifiuti, emergenza pandemica e crisi socio-economica globale sono entrati di fatto nel nostro quotidiano: seppur drammatiche, per certi versi, tali questioni possono essere colte come un’opportunità per ripensare il modo e il mondo in cui viviamo. In questo contesto di ‘rivoluzione’(Floridi, 2020) e di ‘policrisi’ (Losasso, 2020), e con riferimento specifico a…
Thiosulfate Reduction in Salmonella enterica Is Driven by the Proton Motive Force
2012
ABSTRACT Thiosulfate respiration in Salmonella enterica serovar Typhimurium is catalyzed by the membrane-bound enzyme thiosulfate reductase. Experiments with quinone biosynthesis mutants show that menaquinol is the sole electron donor to thiosulfate reductase. However, the reduction of thiosulfate by menaquinol is highly endergonic under standard conditions (Δ E °′ = −328 mV). Thiosulfate reductase activity was found to depend on the proton motive force (PMF) across the cytoplasmic membrane. A structural model for thiosulfate reductase suggests that the PMF drives endergonic electron flow within the enzyme by a reverse loop mechanism. Thiosulfate reductase was able to catalyze the combined …
Role of tir and intimin in the virulence of rabbit enteropathogenic Escherichia coli serotype O103:H2.
2000
ABSTRACT Attaching and effacing (A/E) rabbit enteropathogenic Escherichia coli (REPEC) strains belonging to serogroup O103 are an important cause of diarrhea in weaned rabbits. Like human EPEC strains, they possess the locus of enterocyte effacement clustering the genes involved in the formation of the A/E lesions. In addition, pathogenic REPEC O103 strains produce an Esp-dependent but Eae (intimin)-independent alteration of the host cell cytoskeleton characterized by the formation of focal adhesion complexes and the reorganization of the actin cytoskeleton into bundles of stress fibers. To investigate the role of intimin and its translocated coreceptor (Tir) in the pathogenicity of REPEC, …
Foodborne pathogens inactivation in low-water activity foods
2016
Dried food products are common in food industry. Nevertheless, their safety is not well insured, involving numerous outbreaks every years around the world. Particularly, two pathogenic bacteria are of interest, one of them due to its number of cases, Salmonella enterica, and the other one due to its ability to survive environmental perturbations, Cronobacter spp.. A deeper comprehension of drying and heat treatment in dried state impact could lead to an optimization of drying and heating processes, insuring food safety. In the first instance, drying was considered as a supplementary decontamination step by optimizing its conditions of use. In a second phase, the rehydration impact was studi…
Transformation of Campylobacter jejuni
2000
Campylobacter jejuni is a Gram-negative bacterium and is a commensal of many animal species (Skirrow and Blaser, 1992). In humans it is the major cause of human bacterial enteritis both in developed and developing countries (Tauxe, 1992; Taylor, 1992). Many cases of Campylobacter enteritis in humans have been associated with the consumption of or contact with undercooked chicken meat (Deming et al., 1987; Harris et al., 1986).
Quot philosophi, tot sanniones: las descripciones de filósofos en la sátira latina
2019
El artículo trata la descripción de los filósofos y pseudofilósofos en la sátira latina. A una breve introducción donde se recalca cómo el ataque personal era un elemento clave en este género, sigue un examen de las descripciones insertas en lo que convencionalmente se conoce como sátira regular, pese a que Varrón también aparece incluido con la intención de completar el panorama. El análisis diacrónico de las descripciones invita a pensar que se trata de un tópico especialmente activo en la poesía satírica y que tiende a incrementarse con el paso del tiempo, proporcionando siempre una imagen negativa de los falsos sabios. Si juzgar la finalidad de este recurso de forma global es complicado…
The internationalization of andalusian innovative companies. Mechanisms, evolution, phases and key variables
2009
En este artículo se presenta una tipología del grado de internacionalización que poseen las empresas innovadoras andaluzas en función del modo que han elegido para operar en cada país o mercado y de diferentes variables que nos ha permitido deducir que, en la actualidad, Andalucía se encuentra en las primeras etapas de la globalización. La internacionalización de la empresa ubicada en Andalucía está asociada sobre todo a la exportación directa e indirecta (ya sea como proveedora de inputs a firmas foráneas o compradora de inputs especializados en el mercado internacional). La estrategia de internacionalización mediante intercambio de conocimiento (acuerdos contractuales y de cooperación en …
