Evaluation of the enhanced resistance of Ogataea (Hansenula) polymorpha to benzalkonium chloride as a resource for bioremediation technologies
2019
Abstract Benzalkonium chloride (BAC) is highly abundant in wastewaters due to its wide application in household and industrial products. The aim of this research was to compare the resistance of two genetically related strains, Ogataea polymorpha (wild type) and O. polymorpha cat8Δ (recombinant strain), to enhanced concentrations of BAC (≥ 100 mg/L) in terms of its appearance in wastewaters. Inhibition of the respiration activity of wt and cat8Δ by 100 mg/L and 300 mg/L BAC in a xylose-containing broth (4 g/L xylose) was dependent on the carbon source used for obtaining the yeast biomass through ethanol fermentation. The respiration activity of wt in a liquid broth was inhibited by BAC, whi…
Somatic Hybridization in the Family Apocynaceae (Catharanthus, Rauwolfia, Rhazya, and Vinca Species)
1994
The Apocynaceae family includes about 2000 species belonging to approximately 200 genera (Takhtadjan 1981). The majority of species originate in the tropics, only a few of them are common to Europe (Vinca minor, V. herhaceae, V. major, genus Trachomitum).
Race, ethnicity and ‘African-ness’ in football discourse : perspectives in the age of superdiversity
2018
Globalization, mass mobility, and economic and transcultural flows are changing the experience of diversity in many contemporary societies and communities. This is encapsulated in the notion of ‘superdiversity’, the growing complexity of what ‘diversity’ means, when new combinations of ethnicity and other variables, mobility, belonging, and identification intersect in complex, less predictable ways (see Creese & Blackledge 2010: 550–552; Blommaert & Rampton 2011). Also, the world of association football (soccer, henceforth ‘football’) is radically transformed by such processes of globalization (Giulianotti 1999; Giulianotti & Robertson 2009; Kytölä 2013). The mobility of ‘actors-in-the-fiel…
Global and local interactions in football: Comparing the development paths of Finland and Hungary
2018
The aim of this study is to increase understanding of football’s global and local contexts. More specifically, the development paths of Finnish and Hungarian football are explored and compared in four research articles from different perspectives within a global framework. These viewpoints, in addition to a historical-sociological overview in the article I, cover closely interrelated phenomena observable in the landscape of top-level football: the organization of elite youth football, the professionalization of players and the development of football stadiums. The main research question of the study is as follows: In what way have glocal interactions in men’s football shaped the development…
Quadriceps and hamstring muscle EMG activity during a football match
2012
Roudi Kalema (2012). Quadriceps and hamstring muscle EMG activity during a football match. Department of Biology of Physical, University of Jyvaskyla. Master’s Thesis in Exercise Physiology. 58 pages. Fatigue represents a reduction in the ability of muscle to generate force and in the context of football, it has been often related with injury. Surface electromyography is a valuable technique for evaluating muscle activation and fatigue but it has never been applied during a football match. The development of washable textile electrodes has opened up possibilities to investigate muscular activity in non-laboratory settings, without skin preparation and wires hanging around the body. It has a…
The role of leadership in a national team’s success
2022
Every elite football team wants to maximize their success. Especially in international football, smaller footballing countries need to perform well as underdogs when pursuing qualification to the group stage phase of international tournaments. With limited player options, development of leadership within the team might be one solution to achieve better results. The purpose of this study was to find out team members’ perceptions on what kind of leadership behaviours and leadership structures occur in a men’s football national team participating in the UEFA Euro 2020 and how those are connected to the team’s success. Due to the precise nature of the target sample, we applied a qualitative app…
Adherence to an Injury Prevention Warm-Up Program in Children’s Soccer : A Secondary Analysis of a Randomized Controlled Trial
2021
This study examined the impact of high adherence to a neuromuscular training (NMT) warm-up on the risk of lower extremity (LE) injuries in children’s soccer. Twenty U11–U14 youth clubs (n = 92 teams, 1409 players) were randomized into intervention (n = 44 teams) and control (n = 48 teams) groups. The intervention group was advised to perform an NMT warm-up 2 to 3 times a week for 20 weeks. Team adherence, injuries, and exposure were registered throughout the follow-up. Primary outcomes were the incidence of soccer-related acute LE injuries and the prevalence of overuse LE injuries. Intervention teams conducted mean 1.7 (SD 1.0) NMT warm-ups weekly through follow-up. The seasonal trend for a…
