Bounded weak solutions to superlinear Dirichlet double phase problems

2023

AbstractIn this paper we study a Dirichlet double phase problem with a parametric superlinear right-hand side that has subcritical growth. Under very general assumptions on the data, we prove the existence of at least two nontrivial bounded weak solutions to such problem by using variational methods and critical point theory. In contrast to other works we do not need to suppose the Ambrosetti–Rabinowitz condition.

In-Work Benefits for Married Couples: An Ex-Ante Evaluation of EITC and WTC Policies in Italy

2012

This paper investigates labor supply and redistributive effects of in-work benefits for Italian married couples using a tax-benefit microsimulation model and a multi-sectoral discrete choice model of labor supply. We consider in-work benefits based on the Earned Income Tax Credit (EITC) and the Working Tax Credit (WTC) existing in the US and the UK, respectively. The standard design of these income support mechanisms is however augmented with a premium for two-earner households to avoid potential disincentive effects on secondary earners. Revenue neutral policy simulations show that our reforms may greatly improve the current Italian tax-benefit system in terms of both incentive and redistr…

Taxation in Romania – Some Positive Aspects

2013

Abstract The field of taxation is often a subject of analysis, due to its importance for the formation and administration of public financial resources. By taking into account the local, national and international size of taxation, may be thus identified strengths, weaknesses, opportunities and threats. Although the taxation in Romania is often criticized both by taxpayers and by specialists, there is a progress in taxation field as a result of actions taken in forming and managing fiscal revenues. Without claiming an exhaustive approach, through this article we mention some positive aspects of Romanian taxation. We believe that these should be consolidated and continued.

Should all the world be taxed?

1997

Governments are beginning to fear that the establishment of the “information society” will cause their revenue from taxation to shrink: economic activities in the virtual world of the Internet could escape the application of value added tax. Are these fears justified? Would a “bit tax” solve the problem?

The double uterus associated with an obstructed hemivagina: Clinical management

1991

Abstract The clinical management of It) patients, 9 with uterus didelphys and 1 with complete septate uterus associated with an obstructed hemivagina, is described. The diagnostic evaluation revealed a complete unilateral obstruction in four patients, and an anomalous communication between the two uterovaginal channels in six. In all such patients, the presence of regular menses is frequently misleading, perhaps resulting in unnecessary laparotomy and inadequate or extirpative surgery with negative reproductive consequences. However, diagnosis is simplified if the gynecologist is aware of the malformation. Recommended treatment consists of evacuation of the retained menstruum and excision o…

Articaine versus lidocaine inferior alveolar nerve block in posterior mandible implant surgeries: a randomized controlled trial

2023

Background: The aim of this study is to compare the effects of %4 articaine and %2 lidocaine on inferior alveolar nerve block (IANB) for implant surgery in the posterior mandible.Material and Methods: The patients who have inserted implants in the posterior mandible were divided into 2 groups for IANB: lidocaine and articaine. VAS = visual analog scale, pain during surgery and injection, lip numb-ness time, mandibular canal-implant apex distance, age, gender, bone density, implant number, release incision, adjacent teeth, and duration of surgery were analyzed using t-test, Mann-Whitney U test, Spearman's coefficient, and, Pearson's chi-squared test. This trial followed the recommendations o…

Electric Field Control of Spin-Dependent Dissipative Electron Transfer Dynamics in Mixed-Valence Molecules

2015

We demonstrate that the borderline class II/III magnetic MV dimers, which can be referred to as single molecule multiferroics, provide a unique possibility to achieve electric field control of the electron transfer (ET) dynamics. As an example, we consider a MV dimer d2-d1 in which an extra electron is delocalized over two spin-cores (s0 = 1/2), and the ET is spin-dependent due to the double exchange mechanism. It is assumed that the “extra” electron is coupled to the only intramolecular vibration, and a weak coupling to the dissipative subsystem (thermal bath) is taken into account. The vibronic energy levels and the wave functions of the isolated dimer (quantum part of the system) are num…

Interplay of spin-dependent delocalization and magnetic anisotropy in the ground and excited states of [Gd2@C78]− and [Gd2@C80]−

2017

The magnetic properties and electronic structure of the ground and excited states of two recently characterized endohedral metallo-fullerenes, [Gd2@C78]- (1) and [Gd2@C80]- (2), have been studied by theoretical methods. The systems can be considered as [Gd2]5+ dimers encapsulated in a fullerene cage with the fifteen unpaired electrons ferromagnetically coupled into an S = 15/2 high-spin configuration in the ground state. The microscopic mechanisms governing the Gd-Gd interactions leading to the ferromagnetic ground state are examined by a combination of density functional and ab initio calculations and the full energy spectrum of the ground and lowest excited states is constructed by means …

Un caso di copertura a doppia calotta a Palermo: analisi e rappresentazione del congegno presbiteriale della Badia Nuova

2022

The church of the Badia Nuova in Palermo, which arose in the 16th century and subjected to continuous renovations, stands out as an isolated case in the Palermo scene for its ingenious double-shell dome solution in the presbytery area. The aim of the research is to analyse the architectural design for a comprehension of the relationships between light and space.
