Modelació de sedimentadors en plantes de tractament d’aigües residuals. Aplicació al procés de fermentació – elutriació de fangs primaris
2005
La depuració de les aigües residuals requereix la consumació de molts processos de transformació de forma simultània i/o consecutiva, que fan molt difícil el seu estudi. A més, la complexitat dels processos de depuració va en augment no sols per l'aparició de requisits d’abocament cada vegada més exigents, sinó també per les noves tendències cap al desenvolupament sostenible aplicades a aquest procés i centrades fonamentalment en l’estalvi energètic i la recuperació de nutrients de les aigües residuals per millorar el seu cicle de vida. Per aquest motiu, es fa necessari l'ús d'eines de simulació que tinguen en compte tots aquests processos mitjançant un model matemàtic adequat i ajuden a de…
Impact of physical effort on von Willebrand factor’s activity and concentration in blood
2020
Background and Study Aim: Physical exercise causes a wide range of physiological changes including the production and release of haemostasis regulating factors. One of these factors is von Willebrand factor (vWf)- a glycoprotein responsible for both platelet adhesion and coagulation cascade. Material and Methods: The impact of physical effort on von Willebrand’s factor’s concentration (vWf:Ag) and activity (vWf:CBA) underwent analysis in the group of 42 people (22 men and 20 women) aged 19-22 (mean 20, SD 8 months). Physical effort was induced by 35 minutes of swimming in indoor swimming pool. Results: Physical exercise in form of swimming causes an increase of Willebrand’s factor’s concent…
Oppitaipaleella : katsaus monikielisyyteen päiväkodista yhdeksännelle
2009
Tässä luvussa teen kielen oppimisen näkökulmasta hieman tarkemman katsauksen lasten ja nuorten oppitaipaleeseen päiväkodista peruskoulun päättövaiheeseen. Keskiössä ovat maahanmuuttajataustaiset lapset ja erityisesti suomen kielen kehittyminen, mutta on syytä muistaa, että - parhaimmillaan - näissä instituutioissa myös suomenkieliset juuriltaan suomalaiset kylpevät sekä kulttuureissa että kielissä. Tarkemmin ja konkreettisemmin luvussa keskitytään kuudesluokkalaisiin helsinkiläisiin koululaisiin ja heidän tilanteeseensa esimerkkitapauksena. peerReviewed
Primary total hip arthroplasty with fourth-generation ceramic bearings: Clinical and survival results with a minimum follow-up of 5 years.
2019
Abstract Objective To evaluate the clinical results and survival of primary hip prosthesis with ceramic delta bearings (C-C) with a minimum follow-up of 5 years. Material and method A total of 205 primary hip arthroplasties performed between 2008 and 2012 were studied. The clinical results, pre-surgical and at 5 years of follow-up were evaluated using the Harris Hip Score (HHS), the Short Form-36 (SF-36), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the visual analogue scale (VAS). The position of the prosthetic components, periprosthetic osteolysis, loosening of the prosthetic components and ruptures of the ceramic components were studied radiologically. …
Lateral Ligament Reconstruction
2019
The lateral collateral ligament complex represents the primary lateral elbow ligament stabilizers. In cases of lateral elbow instability, surgical treatment is recommended. Repair should be anatomical and should restore stability to the elbow in order to permit an early active range of motion. Anatomic repair of soft tissue avulsions from bone can be performed with trans-osseous suture or suture anchors. Reconstruction may be required in severe cases and where primary repair is not possible. This chapter describes the surgical techniques for repair and reconstruction of the lateral collateral ligament of the elbow.
mRNA expression profiles of primary high-grade central osteosarcoma are preserved in cell lines and xenografts
2011
Abstract Background Conventional high-grade osteosarcoma is a primary malignant bone tumor, which is most prevalent in adolescence. Survival rates of osteosarcoma patients have not improved significantly in the last 25 years. Aiming to increase this survival rate, a variety of model systems are used to study osteosarcomagenesis and to test new therapeutic agents. Such model systems are typically generated from an osteosarcoma primary tumor, but undergo many changes due to culturing or interactions with a different host species, which may result in differences in gene expression between primary tumor cells, and tumor cells from the model system. We aimed to investigate whether gene expressio…
Total Elbow Replacement as Primary Treatment for Complex Fractures of the Distal Osteopenic Humerus
2003
Background: The use of hip and shoulder arthroplasty in elderly patients for grossly displaced intraarticular fractures is becoming more and more accepted. Total elbow replacement (TER) has not been considered an option for the treatment of extensively comminuted fractures of the distal humerus because surgeons feel the outcome is generally not predictable after TER. Evaluation of TER: On the basis of a MEDLINE literature search of this issue and the documented results based on the improvement of implant designs, operative technique and patient selection, TER has a definite role in the treatment of some fractures of the distal humerus.
Treatment of Combined Medial and Lateral Collateral Ligament Insufficiency
2016
The medial and lateral collateral ligament complexes represent primary elbow ligament stabilizers. Injury to these structures may occur because of an elbow dislocation or due to a severe varus or valgus force. Most elbow dislocations are stable once reduced and may be treated conservatively. However, if the elbow remains unstable surgical treatment is recommended. Repair should be anatomical and should restore stability to the elbow in order to permit an early active range of motion. Reconstruction may be required in severe cases and where primary repair is not possible. Depending on the degree of instability, either one or both of the collateral ligament complexes may need to be repaired o…
Effects of coaching on generalist primary music teachers´ classroom practice and their `musical self-concept´
2016
The majority of music lessons in primary schools are covered by generalist primary music teachers, usually with little or no training in teaching it. This practice-based research project is part a PhD program to professionalize generalist music teachers in primary schools to teach music lessons. The aim of this study was to describe changes in the generalist primary music teachers´ didactic classroom practices in teaching music. Moreover, this study aimed to analyze the generalist primary music teachers´ development of their `musical self-concept` (Spychiger, 2010). This longitudinal intervention study is qualitative in character. Participants were 8 generalist primary music teachers and 4 …
Students’ experiences of their agency in whole-class playing
2022
The agency of primary school students has been studied increasingly in recent years; yet, we know relatively little about student agency in music educational settings or how students experience their participation in joint musical action. This study explores sixth-grade students’ experiences of their agency in whole-class playing. Qualitative content analysis of 11 pair interviews identified vulnerability as an essential element of participating in whole-class playing, highlighting the intrinsically emotional nature of the process, the immediacy of the musically shared moment and the safe place of entrainment. This study elucidates the enactment of agency and the resources facilitating and …
