Imaging of non-glandular superficial metastases: A comparison of xeroradiography, ultrasonography and computed tomography
1989
Between January 1983 and July 1987, 1,622 cancer patients were evaluated to outline the possible applications and limits of various investigative techniques for evaluating metastases. Seventy-three cases with superficial metastases of the dermal-hypodermal (59) layers, of the muscles (11) and of other target organs (3) were included in the study. Although non-glandular superficial metastases are a relatively rare occurrence, diagnostic imaging techniques are indicated for evaluating their extent and anatomical connections. Secondary neoplasms were studied using the imaging techniques of sonography, computed tomography and xeroradiography. The diagnostic reliability of these three techniques…
OFN Capital Budgeting Under Uncertainty and Risk
2017
The aim of this chapter is to propose a new approach to incorporating uncertainty into capital budgeting. The chapter presents methods that can be used by an investor when the decision maker wants to be able to make an investment decision where there are alternative investment projects. This kind of problem is undertaken under the conditions of uncertainty and risk using Ordered Fuzzy Numbers (OFN). The starting point is the concept of Ordered Fuzzy Numbers. The chapter illustrates the implementation of the proposed approach with an example where two alternative investment projects are analyzed. The authors present the capital budgeting problem using a numerical example. The described metho…
A comparative economic analysis of torrefied pellet production based on state-of-the-art pellets
2017
Abstract Torrefied pellets have fuel properties superior to those of conventional wood pellets and potentially allow greater rates of co-firing and thus larger reductions in net CO 2 emissions. Despite the growing amount of scientific output on torrefaction, the economic feasibility of torrefied pellet production is still a topic of considerable uncertainty. This is an obstacle for decision makers looking to implement sustainable energy policies. This paper compares the economics of torrefied pellets to conventional wood pellets. Working backwards from demonstrated pellet properties, this work attempts to answer the following question: Based on state-of-the-art torrefied pellets, what would…
A novel thermoeconomic analysis under dynamic operating conditions for space heating and cooling systems
2019
Abstract Thermoeconomic analysis allows for a deep understanding of the cost formation process within an energy system, providing insights into the possible routes for improvement. Several thermoeconomic approaches are well-established for application in systems with steady operating conditions, such as power plants, while a limited number of applications to air-conditioning systems in buildings have been proposed, due to the difficulties in dealing with very irregular load profiles and unsteady plant operating conditions. This study investigates the potential of Thermoeconomics as a support for decision making in building energy systems, proving its capability to identify trade-offs betwee…
Foreign Direct Investment Drivers in Romania
2013
Foreign Direct Investment (FDI) represents a condition sine qua non for a sustainable development of Romania, taking into consideration the fact that the domestic capital is not enough to assure a positive and significant growth. The present study uses the multiple linear regression to determine the main factors which influence FDI level in Romania. The international reserve and the capital market index BET have a direct and positive impact on the foreign investment flow, while the short, medium and long private and public external debt proved to influence direct, but in a negative way, the FDI.
The importance of relation-specific investments in capital structure decision: the case of the biopharmaceutical industry
2012
According to capital structure literature, bilateral relationships with external partners have a strong impact on a firm’s financing decisions because they involve relation-specific investments that would lose most of their value in case of liquidation. By adjusting their capital structure firms can reduce liquidation risks and incentive their partners to undertake such investments. In this paper we extend these arguments to strategic alliances in the context of biotechnology industry, where bilateral relationships are formed to advance the commercialization of innovation and R-S investments are a primary issue. We investigate alliances heterogeneity and analyze whether partnerships possess…
Safety and efficacy of left atrial appendage occlusion with the ACP or Watchman device guided by intracardiac echocardiography from the left atrium
2021
Abstract Background There is a paucity of randomized data regarding the safety and efficacy of the use of intracardiac echocardiography (ICE) from the left atrium (LA) to guide left atrial appendage occlusion (LAAO) procedures under local anesthesia using either of the available devices. Hypothesis The aim of this study was to compare the efficacy and safety of ICE from the LA with transesophageal echocardiography (TEE) for guidance during transcatheter LAAO procedures. Methods Single‐center, cohort study of patients undergoing LAAO with the Amplatzer Cardiac Plug or Watchman device. Procedures were guided by ICE from the LA with local anesthesia (n = 175) or TEE under general anesthesia (n…
Association of Global Longitudinal Strain With Clinical Status and Mortality in Patients With Chronic Heart Failure.
2021
IMPORTANCE: Global longitudinal strain (GLS) is an emerging echocardiographic biomarker of cardiac function in heart failure (HF). Evidence from large-scale studies comprehensively investigating GLS for its association with clinical phenotypes and mortality in asymptomatic and symptomatic chronic HF is limited. OBJECTIVE: To assess the factors associated with GLS and its prognostic value in patients with chronic HF. DESIGN, SETTING, AND PARTICIPANTS: The observational, prospective MyoVasc cohort study enrolled 3289 individuals with asymptomatic to symptomatic HF between January 17, 2013, and April 27, 2018. The median follow-up was 3.2 years (interquartile range, 2.0-4.0 years). Participant…
Dalla mafia al terrorismo e viceversa: il metodo dalla Chiesa
2017
In this paper it is assumed that the connection between the repression the mafia and terrorism are inseparable: without the fight against terrorism there would not have been the mafia; in the legal field, as well as that of investigative, penitentiary, political institutions and administrative. The connection between these two different criminal experiences, that have so bloody pages in the history of Italy Republican, is represented by the figure and the action of Carlo Alberto dalla Chiesa and from his "method" of work
Preclinical atherosclerosis and metabolic syndrome increase cardio- and cerebrovascular events rate: a 20-year follow up
2013
BACKGROUND: Intima-media thickness (IMT) is a validated marker of preclinical atherosclerosis and a predictor of cardiovascular events. PATIENTS: We studied a population of 529 asymptomatic patients (age 62 ± 12.8 years), divided into two groups of subjects with and without Metabolic Syndrome (MetS). METHODS: All patients, at baseline, have had a carotid ultrasound evaluation and classified in two subgroups: the first one without atherosclerotic lesions and the second one with preclinical atherosclerosis (increased IMT or asymptomatic carotid plaque). Cardiovascular endpoints were investigated in a 20-years follow-up. RESULTS: There were 242 cardiovascular events: 144 among patients with Me…
