Increased ventilation by fish leads to a higher risk of parasitism
2014
Background: Fish are common intermediate hosts of trematode cercariae and their gills can potentially serve as important sites of penetration by these larval stages. We experimentally tested the hypothesis that volume of ventilation flow across the gills contributes to acquisition of these parasites by fish. We manipulated the intensity of ventilation by using different oxygen concentrations. Methods: Juvenile Oncorhynchus mykiss were individually exposed for 10 minutes to a standard dose of Diplostomum pseudospathaceum cercariae at three levels of oxygen concentration, 30, 60 and 90%. Ventilation amplitude (measured as a distance between left and right operculum), operculum beat rate, and …
Pena "illegale", giudicato, Corte europea: dall'affare "Scoppola c. Italia" alle Sezioni Unite "Ercolano"
2016
Dopo essersi soffermata sul principio dell'intangibilità del giudicato rilevandone la necessità a dovere cedere di fronte alle sollecitazioni europee, l'Autrice focalizza l'attenzione sul canone di retroattività della lex mitior così come interpretato nella sentenza europea "Scoppola", donde il nuovo parametro di costituzionalità nell'ordinamento interno. Il discorso quindi si sposta sui fratelli c.d. minori di Scoppola, rispetto ai quali le Sezioni Unite Ercolano hanno sollevato incidente di costituzionalità a cui segue la sentenza costituzionale n. 210/2013 e la conseguente pronuncia delle Sezioni Unite, analizzate entrambe dall'Autrice che infine si sofferma sui nuovi scenari.
Development of national climate and adaptation policy in Latvia
2009
PurposeThe purpose of this paper is to analyse the development and character of climate policy in Latvia with a special emphasis on policy instruments.Design/methodology/approachIn order to implement policies and measures effectively and monitor progress in achieving its mitigation targets, Latvia uses a wide mix of policy instruments, including regulations (e.g. environmental impact assessment procedures, environmental permits and standards, restrictions and prohibitions), economic and fiscal instruments (the natural resources tax, the excise tax for energy resources, user's charges), and voluntary agreements, also raising public awareness.FindingsThe combination of the policy instruments …
Graphical THD minimization procedure for single phase five-level converters
2017
This paper proposes two graphycal procedure to mitigate h harmonics and to minimize the total harmonic distortion (THD), respectively. The paper considers a five-level inverter and fundamental frequency modulation: it computes the two switching angles able to reduce low order harmonics and able to minimize the THD. Simulation results are obtained and, in order to validate the proposed procedure, an experimental prototype is built and experimental results are carried out. The comparison between simulation and experimental results confirms the accuracy of the proposed graphycal procedure. It is shown that the switching angles to mitigate the third-fifth and the third-fifth-seventh harmonics e…
Is morphokinetic analysis the answer?
2013
Abstract Efforts aimed at improving pregnancy rates have focused on the search for additional markers of viability to supplement current criteria for embryo selection. Time-lapse technology represents a powerful tool in assisted reproduction for evaluating embryos dynamically. Whilst standard methods of embryo assessment are based on subjective morphology evaluation at discrete time points, thereby limiting the information produced for embryo selection, time-lapse recording introduces several additional morphokinetic parameters for embryo evaluation. This additional information can improve implantation rates and reproductive outcomes. This review surveys available knowledge on time-lapse im…
La reforma de la negociación colectiva en la ley 3/2012
2012
En el presente estudio se analizan las reformas en el régimen jurídico de la negociación colectiva mediante la Ley 3/2012 (precedida por el RDL 3/2012) y el RDL 20/2012, que han perjudicado y dificultado algunas de las funciones esenciales de la negociación colectiva para la evitación de vacíos de regulación, progreso en las condiciones de trabajo y freno a la individualización, y que han hecho girar el eje de la negociación hacia la empresa, solución poco realista en un marco productivo dominado por la microempresa y que otorga más poder al empleador. Las reformas han afectado sobre todo a la situación del convenio una vez finalizada su vigencia pactada (régimen de prórroga), a la estructu…
Inverse eigenvalue problem for normal J-hamiltonian matrices
2015
[EN] A complex square matrix A is called J-hamiltonian if AT is hermitian where J is a normal real matrix such that J(2) = -I-n. In this paper we solve the problem of finding J-hamiltonian normal solutions for the inverse eigenvalue problem. (C) 2015 Elsevier Ltd. All rights reserved.
A chain of solvable non-Hermitian Hamiltonians constructed by a series of metric operators
2021
We show how, given a non-Hermitian Hamiltonian $H$, we can generate new non-Hermitian operators sequentially, producing a virtually infinite chain of non-Hermitian Hamiltonians which are isospectral to $H$ and $H^\dagger$ and whose eigenvectors we can easily deduce in an almost automatic way; no ingredients are necessary other than $H$ and its eigensystem. To set off the chain and keep it running, we use, for the first time in our knowledge, a series of maps all connected to different metric operators. We show how the procedure works in several physically relevant systems. In particular, we apply our method to various versions of the Hatano-Nelson model and to some PT-symmetric Hamiltonians.
Simple method for limiting delay of optimized interleavers for turbo-codes
2000
An iterative interleaver growth algorithm is extended to allow the delay and required memory of designed interleavers to be halved with negligible performance loss. The original algorithm is efficient for two-component parallel concatenated turbo-codes with given constituent encoders that are optimum with regard to a cost function satisfying some mild conditions. However, it is only actually optimum if the selected set of patterns is representative of low-weight turbo-codewords. The new interleaver uses all terminating error patterns having an input weight not greater than a fixed IWX and single-coder output weight not greater than WX is proposed.
De novo 13q deletions in two patients with mild anorectal malformations as part of VATER/VACTERL and VATER/VACTERL-like association and analysis of E…
2013
Item does not contain fulltext Anorectal malformations (ARMs) comprise a broad spectrum of conditions ranging from mild anal anomalies to complex cloacal malformations. In 40-50% of cases, ARM occurs within the context of defined genetic syndromes or complex multiple congenital anomalies, such as VATER/VACTERL (vertebral defects [V], ARMs [A], cardiac defects [C], tracheoesophageal fistula with or without esophageal atresia [TE], renal malformations [R], and limb defects [L]) association. Here, we report the identification of deletions at chromosome 13q using single nucleotide polymorphism-based array analysis in two patients with mild ARM as part of VATER/VACTERL and VATER/VACTERL-like ass…
