Analysis and evaluation of periodic physiological organ motion in radiotherapy treatments.
2003
Background and purpose: A system for the detection, measurement and analysis of the periodic physiological organ motion during radiotherapy treatment is proposed and clinically tested in this paper. Material and methods: The procedure is based on the acquisition of fluoroscopic sequences, followed by an automatic detection of the movement using cross-correlations with matched filters. Results: The system generates a probability density function (PDF) of finding a mobile organ in a position at a certain time. The maximum path of the mobile structures can be determined to define the planning target volume (PTV) without ambiguities. Conclusions: Physiological movements can be accurately includ…
Inhaled amikacin versus placebo to prevent ventilator-associated pneumonia: the AMIKINHAL double-blind multicentre randomised controlled trial protoc…
2021
IntroductionPre-emptive inhaled antibiotics may be effective to reduce the occurrence of ventilator-associated pneumonia among critically ill patients. Meta-analysis of small sample size trials showed a favourable signal. Inhaled antibiotics are associated with a reduced emergence of antibiotic resistant bacteria. The aim of this trial is to evaluate the benefit of a 3-day course of inhaled antibiotics among patients undergoing invasive mechanical ventilation for more than 3 days on the occurrence of ventilator-associated pneumonia.Methods and analysisAcademic, investigator-initiated, parallel two group arms, double-blind, multicentre superiority randomised controlled trial. Patients invasi…
Supraglottic airway devices for surfactant treatment: systematic review and meta-analysis
2019
Objective: To compare surfactant administration via supraglottic airway device (SAD) vs. nasal CPAP alone or INSURE. Study design: A systematic search of PubMed, EMBASE, SCOPUS, Cochrane Central Register of Controlled Trials and Clinicaltrials.gov was performed. Articles meeting inclusion criteria (RCT, surfactant administration via SAD, laryngeal mask, I-gel) were assessed Results: Five RCTs were eligible. Surfactant administration via SAD reduced the need for intubation/mechanical ventilation (RR 0.57, 95%CI 0.38–0.85) and short-term oxygen requirements (MD −8.00, 95%CI −11.09 to −4.91) compared to nCPAP alone. Surfactant administration via SAD reduced the need for intubation/mechanical v…
Fractal-like Hierarchical CuO Nano/Microstructures for Large-Surface-to-Volume-Ratio Dip Catalysts
2022
Dip catalysts are attracting interest in both academia and industry for catalyzing important chemical reactions. These provide excellent stability, better recoverability, recyclability, and easy scale-up. Using the unique microstructures of leaf skeletons, we present a fractal-like hierarchical surface that can be used as a versatile and efficient dip catalyst. Copper oxide microcactuses with nanoscalar features were fabricated onto the Bauhinia racemosa leaf skeletons via a combination of physical vapor deposition, electroplating, and chemical oxidation methods. The coated leaf skeletons have a very high surface area, and the three-dimensional (3D) morphology allows the reactants to encoun…
Music piracy culture in the Internet
2011
The purpose of the research was to identify the motivations and opinions on copyright and online music piracy on the Internet through Peer-to-peer (P2P) Networks. The research was carried out as a Master's Thesis in the Digital Culture program at the University of Jyväskylä. Quantitative research methodology was utilized in the form of questionnaires, which were distributed for two weeks through the mailing list and personal invitations at the University of Jyväskylä. 48 responses from people of 22 nationalities were received. Analysis of the questionnaires revealed opinions that people conduct music file sharing on P2P networks because it is convenient, promotes musicians and is environmen…

Aspiracje edukacyjne i zawodowe oraz zamierzenia migracyjne młodzieży z województwa podkarpackiego w świetle badań empirycznych
2018
Artykuł prezentuje wyniki socjologicznych badań sondażowych nad dążeniami życiowymi młodzieży z województwa podkarpackiego w kontekście przyszłości tego regionu. Wśród młodzieży dominuje chęć nauki na studiach wyższych, w bardzo dobrym ośrodku akademickim z tradycjami. Młodzi ludzie oceniają również region jak tradycyjny i konserwatywny oraz mało postępowy. W związku z tym utrzymują się nadal wysokie skłonności migracyjne wśród młodzieży, zarówno wewnętrzne jak i zagraniczne, co zagraża harmonijnemu rozwojowi regionu w przyszłości. Natomiast Podkarpackie nie jest raczej zagrożone „pułapką niskiej dzietności", bowiem wśród młodzieży był popularny model rodziny tradycyjnej, z dwojgiem dzieci,…
Nuoret aikuiset maksullisten suoratoistopalvelujen kuluttajina
2017
Suoratoistopalvelut ovat nykyään pohjoismaissa erittäin suosittuja ja yli 80 prosenttia suomalaisista on katsonut viimeisen puolen vuoden aikana suoratoistosisältöä. Tosin aikaisempien tutkimusten mukaan suoratoistosisällöistä maksaneiden osuus on ollut Suomessa pohjoismaiden pienin. Tämän tutkielman tavoite oli selvittää, kuinka paljon nuoret suomalaiset aikuiset ovat valmiita maksamaan suoratoistopalvelujen käytöstä, kuinka halukkaita he ovat käyttämään maksullisia suoratoistopalveluja ja mitkä tekijät vaikuttavat maksullisten suoratoistopalvelujen omaksumiseen. Tutkimus toteutettiin kirjallisuuskatsauksena ja strukturoituna kyselytutkimuksena. Tutkimuksen aineisto kerättiin touko-kesäkuu…
Musiikkipiratismi 2010-luvun nuorten keskuudessa - erityispiirteet ja neutralisaatiot
2012
Tässä pro gradu -tutkielmassa tarkasteltiin 2010-luvun nuorten harjoittamaa musiikkipiratismia soveltamalla Gresham Sykesin ja David Matzan neutralisaatioteoriaa. Tutkielman keskiössä oli kysymys siitä, pitävätkö niin kutsuttuun Z-sukupolveen kuuluvat tämän päivän nuoret musiikki- tai muuta Internet-piratismia eettisesti kestävänä toimintamallina. Erityisen kiinnostuksen kohteina olivat neutralisaatioteorian käsitteistöön kuuluvat neutralisaation tekniikat ja niiden käyttö musiikkipiratismin yhteydessä. Tutkielmassa sovellettiin laadullista tutkimusotetta: tutkimusmenetelminä käytettiin kirjallisuuskatsausta ja puolistrukturoituja haastatteluja. Tutkimuksen perusteella Z-sukupolvi tunnistaa…
Protective ventilation with high versus low positive end-expiratory pressure during one-lung ventilation for thoracic surgery (PROTHOR): study protoc…
2019
Background: Postoperative pulmonary complications (PPC) may result in longer duration of in-hospital stay and even mortality. Both thoracic surgery and intraoperative mechanical ventilation settings add considerably to the risk of PPC. It is unclear if one-lung ventilation (OLV) for thoracic surgery with a strategy of intraoperative high positive end-expiratory pressure (PEEP) and recruitment maneuvers (RM) reduces PPC, compared to low PEEP without RM. Methods: PROTHOR is an international, multicenter, randomized, controlled, assessor-blinded, two-arm trial initiated by investigators of the PROtective VEntilation NETwork. In total, 2378 patients will be randomly assigned to one of two diffe…
