Luonto ja eläimet Eija-Liisa Ahtilan teoksessa Tänään
2014
Sivuttukielmassa käsitellään taiteilija Eija-Liisa Ahtilan kolmikanavaista videoinstallaatiota Tänään (1996–1997). Erityisesti pohditaan teoksesta avautuvia käsityksiä luonnosta ja eläimistä. Taustaksi tutkimukselle esitellään videoinstallaatioiden kehitystä taidemuotona 1990-luvun lopulla sekä erityisesti Eija-Liisa Ahtilan tapoja käyttää monikuvainstaalaatiota taiteensa välineenä. Myös Ahtiloan tuotannossa olennaiset käsitteet aika, paikka ja subjekti tulevat myös kytketyiksi tutkimukseen.

Changes in sprint performance and sagittal plane kinematics after heavy resisted sprint training in professional soccer players
2019
Background Sprint performance is an essential skill to target within soccer, which can be likely achieved with a variety of methods, including different on-field training options. One such method could be heavy resisted sprint training. However, the effects of such overload on sprint performance and the related kinetic changes are unknown in a professional setting. Another unknown factor is whether violating kinematic specificity via heavy resistance will lead to changes in unloaded sprinting kinematics. We investigated whether heavy resisted sled training (HS) affects sprint performance, kinetics, sagittal plane kinematics, and spatiotemporal parameters in professional male soccer players.…
Collecting and Using Students’ Digital Well-Being Data in Multidisciplinary Teaching
2018
This article examines how students (N=198; aged 13 to 17) experienced the new methods for sensor-based learning in multidisciplinary teaching in lower and upper secondary education that combine the use of new sensor technology and learning from self-produced well-being data. The aim was to explore how students perceived new methods from the point of view of their learning and did the teaching methods provide new information that could promote their own well-being. We also aimed to find out how to collect digital well-being data from a large number of students and how the collected big data set can be utilized to predict school success from the students’ well-being data by using machine lear…

Are urban water bodies really cooling?
2020
Abstract Small urban water bodies, like ponds or canals, are often assumed to cool their surroundings during hot periods, when water bodies remain cooler than air during daytime. However, during the night they may be warmer. Sufficient fetch is required for thermal effects to reach a height of 1–2 m, relevant for humans. In the ‘Really cooling water bodies in cities’ (REALCOOL) project thermal effects of typical Dutch urban water bodies were explored, using ENVI-met 4.1.3. This model version enables users to specify intensity of turbulent mixing and light absorption of the water, offering improved water temperature simulations. Local thermal effects near individual water bodies were assesse…
Komposta zemes ķīmiskā sastāva izvērtējums
2015
Komposta zemes ķīmiskā sastāva izvērtējums. Briedīte B., zinātniskais vadītājs lektore Ķīm. Maģ. Zenta Balcerbule, Kursa darbs, 63 lappuses, 15 attēli, 23 tabulas, 31 literatūras avoti, 1 pielikums, Latviešu valodā. Darbā tika analizēti augsnes un komposta zemes paraugi no ekoloģiskās saimniecības, kā arī dārzniecībā ņemts kūdras paraugs, kurā ir iestrādāti minerālmēsli. Analizējamos paraugos noteica mitrumu, tika izmērīts pH. Jonometriski noteikti NO3- joni, fotometriski ar Neslera reaģentu noteikti NH4+ joni, fotometriski noteikts šķīstošā fosfora daudzums, kā arī ar liesmas fotometru tika noteikts kālija saturs analizējamos paraugos.
