Unconventional Reducing Gases Monitoring in Everyday Places

2017

Abstract Air pollution, be it indoors or outdoors, is a major environmental health concern as it can lead to serious health effects, such as respiratory diseases, including asthma and lung cancer. Much progress has been made in Europe in improving outdoor air quality and limit values have been set for several pollutants. However, indoor air quality also requires attention because this is where we spend most of our time. Measurements at appropriate spatial and temporal scales are essential for understanding and monitoring heterogeneous environments with complex and highly variable emission sources, such as in urban areas. However, the costs and complexity of conventional air quality measurem…

Immediacy and distance in teacher talk—A comparative case study in German elementary- and outdoor school-teaching

2017

This case study examines authentic speech acts by a German primary school teacher in the classroom context and the outdoor learning location of a forest. The study will compare the degree of linguistic immediacy or distance in these two contexts, respectively. Once a week, the class is doing “outdoor school” [Draußenschule] in places of natural or cultural interest near to their school. The structural change in the teaching environment means a change in the communication setting. The question arises if the teacher speaks to the students differently indoors than outdoors. The theoretical reference framework for the study is provided by the linguistic model “language of immediacy and language…

Effect of ambient temperature variations on an indigenous microalgae-nitrifying bacteria culture dominated by Chlorella

2019

[EN] Two outdoor photobioreactors were operated to evaluate the effect of variable ambient temperature on an indigenous microalgae-nitrifying bacteria culture dominated by Chlorella. Four experiments were carried out in different seasons, maintaining the temperature-controlled PBR at around 25¿°C (by either heating or cooling), while the temperature in the non-temperature-controlled PBR was allowed to vary with the ambient conditions. Temperatures in the range of 15¿30¿°C had no significant effect on the microalgae cultivation performance. However, when the temperature rose to 30¿35¿°C microalgae viability was significantly reduced. Sudden temperature rises triggered AOB growth in the indig…

Ārā pavadītā laika ietekme uz miopijas progresēšanu

2021

Bakalaura darbs ir uzrakstīts angļu valodā uz 25 lapaspusēm. Tas satur 13 attēlus, 5 tabulas un 16 literatūras atsauces. Darba mērķis ir novērtēt āra aktivitāšu ietekmi uz miopijas attīstības kavēšanu. Dati tika iegūti ar jautājumu anketu palīdzību. Rezultāti rāda, ka āra aktivitātes šajā pētījumā nav nozīmīgs faktors, kurš kavē miopijas veidošanos (p<0.05). Nozīmīgs miopijas veidošanās faktors ir iedzimtība.

Physical and cognitive doping in university students using the unrelated question model (UQM): Assessing the influence of the probability of receivin…

2018

Study objectives: In order to increase the value of randomized response techniques (RRTs) as tools for studying sensitive issues, the present study investigated whether the prevalence estimate for a sensitive item π̂$_{s}$ assessed with the unrelated questionnaire method (UQM) is influenced by changing the probability of receiving the sensitive question p. Material and methods: A short paper-and-pencil questionnaire was distributed to 1.243 university students assessing the 12-month prevalence of physical and cognitive doping using two versions of the UQM with different probabilities for receiving the sensitive question (p ≈ 1/3 and p ≈ 2/3). Likelihood ratio tests were used to assess wheth…

Benchmarking of outdoor activity facilities : an analysis of German hiking facilities and its implications to Finland

2015

The health effects of regular physical activity play an integral part in the promotion of outdoor participation. Well-maintained and marketed outdoor facilities encourage in this regard people to be more active outside of their homes. The aim of this study is to analyse popular German outdoor facilities in order to identify good working practices in Germany that can potentially be applied in Finland with the purpose of encouraging Finnish people to go outdoors more often. The study was conducted in cooperation between the University of Jyväskylä and Suomen Latu. The main research questions was: What knowledge can Suomen Latu gain from the administration of popular German hiking facilities i…

Optimising an outdoor membrane photobioreactor for tertiary sewage treatment

2019

[EN] The operation of an outdoor membrane photobioreactor plant which treated the effluent of an anaerobic membrane bioreactor was optimised. Biomass retention times of 4.5, 6, and 9 days were tested. At a biomass retention time of 4.5 days, maximum nitrogen recovery rate:light irradiance ratios, photosynthetic efficiencies and carbon biofixations of 51.7¿±¿14.3¿mg¿N·mol¿1, 4.4¿±¿1.6% and 0.50¿±¿0.05¿kg CO2·m3influent, respectively, were attained. Minimum membrane fouling rates were achieved when operating at the shortest biomass retention time because of the lower solid concentration and the negligible amount of cyanobacteria and protozoa. Hydraulic retention times of 3.5, 2, and 1.5 days …

Deception and abuse: Manifold Instances of Proxemic Violence against Sub-Saharan and Eastern-European Women-Immigrants In Sicily

2019

Over the past few decades and up until 2017, Sicily has hosted increasing numbers of African fugitives (ANCI et al., 2017) as well as migrants from Eastern Europe, especially after the entry of Romania into the European Union. The aim of the research was to analyse some of the role positions found in gender dynamics among migrants, throwing light on possible processes by which mechanisms of submission to and normalisation of gender based violence seem to have been internalised by these victims of proximity violence, emphasising the viscous links existing between vulnerability, resistance and resilience. Within this markedly multicultural context in Sicily, the researchers carried out a two-…
