A controlled trial of intra-articular corticosteroids with or without methotrexate in oligoarticular juvenile idiopathic arthritis
2014
In contrast with the numerous controlled trials conducted in polyarticular or systemic juvenile idiopathic arthritis (JIA), little evidence-based information is available for oligoarticular JIA. As a result, the management of children with this subtype, which is the most prevalent in Western countries, is largely empiric. Intra-articular corticosteroid (IAC) injection is the therapy of first choice for oligoarthritis in many pediatric rheumatology centers. However, although IAC injections are usually highly efficacious, relapses of synovitis are common and sometimes occur only a few months after the procedure. It is still unclear whether concomitant administration of methotrexate (MTX) may …
Improving Economic Management Decisions in Forestry with the SorSim Assortment Model
2020
The sustainable supply of timber is one of the most important forest ecosystem services and a decisive factor determining the long-term profitability of forest enterprises. If timber production is to be economically viable, there must always be a way to analyse forest stands and trees felled for exploitation with regard to the wood assortments they contain. Only then can the expected timber yields, achieved by various silvicultural strategies or actions and different sorting options, be quantified with sufficient accuracy. The SorSim assortment simulator was developed for forest practitioners and forest scientists in Switzerland to realistically simulate the sorting of individual trees and …
Real options analysis as a tool for start-up company investment valuation
2015
Pro Gradu -tutkielman tavoitteena oli tutkia Real Option Analysis -metodin sopivuutta start-up yhtiön investoinnin arvonmääritykseen. Jotta tutkimuskysymykseen saatiin vastaus, tuli myös case-yhtiön liiketoimintasuunnitelma selvittää ja edelleen mitkä ovat liiketoiminnan potentiaaliset rahavirrat, joihin arvonmääritys perustuu. Tutkimusmenetelmä oli kvantitatiivinen case-tutkimus ja tutkimusmetodi oli konstruktiivinen ja deskriptiivinen. Tutkimuksessa konstruoitiin työkalu ja arvonmääritys case-yrityksen suunnitellulle investoinnille. Toisaalta tutkimuksessa kuvailtiin arvonmääritystä yleisesti sekä Real Options Analysis -metodia. Tutkimuksen pohjaksi tutustuttiin start-up yhtiöihin, arvonm…
Sensitivity analysis in investment project of biogas plant
2017
The article shows the practical value of biogas as the second generation biofuel. All the projects dealing with biogas are subjected to external risks, such as the change of market condition, customer needs, governmental regulation, etc. In conditions of uncertainty it is necessary for administration to concentrate on decisionmaking. Fluctuations of sales volume, energy resources and raw material prices, etc. should be taken into account. Sensitivity analysis can predict the result of negative external pheno mena. We developed the economic-mathematical model for the analysis of biogas complexes sensitivity. The profitability index as a criterion for the effectiveness of investment projects …
Transcranial Magnetic Stimulation and Neuroimaging Coregistration
2013
The development of neuroimaging techniques is one of the most impressive advancements in neuroscience. The main reason for the widespread use of these instruments lies in their capacity to provide an accurate description of neural activity during a cognitive process or during rest. This important advancement is related to the possibility to selectively detect changes of neuronal activity in space and time by means of different biological markers. Specifically, functional magnetic resonance imaging (fMRI), positron emission tomography (PET), single-photon emission computed tomography (SPECT), and nearinfrared spectroscopy (NIRS) use metabolic markers of ongoing neuronal activity to provide a…

ORAL EXPRESSIVE COMPETENCE’S DEVELOPMENT BY USE OF MINDTOOLS
2015
The aim of this work is to verify the efficacy of a training programme focused on the enhancement of oral expressiveness (the generation of ideas and planning, pragmatic awareness), realized with a group of children between 10 and 12 years, in the last year of primary school and in the first year of secondary school in the Palermo area. The educational activities were conducted from January to June 2014. Action learning provided a learning environment based on real problem solving with team work; the active search for information, discussion and reflection, as well as decision-making, were assisted by semantic networks (concept maps) and knowledge construction tools. Oral presentation, or p…
La ricerca pedagogica e la ricostruzione storica delle buone pratiche nel tempo del presentismo. Riflessioni intorno a un paradigma.
2015
Scopo del presente articolo è di fare chiarezza sul ruolo che oggi le indagini storiche intorno alle pratiche educative rivestono all’interno della ricerca pedagogica. Se, fino a pochi anni fa era opportuno parlare di passaggio dalla storia della pedagogia alla storia dell’educazione, a ben vedere, le attuali ricerche storiche sembrano più orientate a ripensare un dialogo costruttivo e reciproco con il sapere pedagogico. Tra la ricerca pedagogica e la ricerca storico-educativa sembra esservi una nuova sinergia: nel tempo del presentismo, in cui tutto sembra consumarsi velocemente, il pedagogista pensa e agisce a partire da una coscienza storica che lo rende più consapevole del proprio tempo…
Ground-Mounted Photovoltaic and Crop Cultivation: A Comparative Analysis
2022
Human civilization depends on energy sources, mainly fossil fuels. An increase in the prices of fossil fuels and their exhaustibility limit economic growth. Carbon dioxide emission causes global environmental problems. Global crises (including COVID-19) have sharpened food and energy supply problems. The decentralized energy supply systems as well as the expedition of the application of renewable energy may solve these challenges. The economic shift to renewable power generation intensifies the competition between food crop production and green energy for land. This paper applied an open-source spatial-based model to quantify the solar power generation (the ground-mounted photovoltaic panel…
PIG CARCASS CLASSIFICATION IN ROMANIA: A DISSECTION TRIAL FOR THE APPROVAL OF THE “FAT-O-MEAT’ER” AND OF THE “OPTIGRADE-PRO”EQUIPMENT
2014
The objective of this study was to obtain new regression formulas for optical equipment Fat-O-Meat’er and OptiGrade-PRO in pig carcass classification in Romania. The estimation of lean mean content in pig carcasses by means of SEUROP system and following fair payment based on the weight and composition of the carcass pigs in the main objective of classification. Dissection of four main cuts (shoulder, loin, ham, belly) of pig carcasses (n = 145) were performed. The measurement of backfat and muscle depths using probes were taken from the carcasses within 45 min. after slaughter of pigs. Lean meat content estimated using different methods and determined from dissections was equal (56,3 % ). …
