Grasslands provide diverse opportunities for bird species along an urban-rural gradient
2021
Urbanisation is a major cause of biodiversity loss but careful habitat management and provision of green space within cities can help to mitigate its negative effects. Grasslands occupy large surface areas and have many functions but only a few studies have begun to explore how birds exploit these habitats in urban contexts. We hypothesized that the value of grasslands for nesting and feeding birds is likely to depend both on landscape context, and on local characteristics (grassland size, use and vegetation structure). We surveyed local habitat characteristics, breeding bird presence, abundance and foraging activity in 47 grassland sites, distributed along an urban-rural gradient in two Fr…
Mitä mieltä, professorit?
2006
25 vuoden ikään ehtinyt Aikuiskasvatus kysyi kaikilta aikuiskasvatuksen professoreiltamme heidän näkemyksiään neljässä asiassa. Kaikkiin ei tarvinnut vastata. Tällaista kysyttiin ja näin vastasivat Yrjö Engeström ja Reijo Miettinen Helsingin yliopistosta, Anneli Eteläpelto Jyväskylän yliopistosta, Jukka Tuomisto ja Juha Suoranta Tampereen yliopistosta, Risto Rinne Turun yliopistosta, Kari E. Nurmi Lapin yliopistosta sekä vt:nä virkaa hoitava Leena Ahteenmäki-Pelkonen Joensuun yliopistosta. Vastausjärjestys on arvottu.

Establishing a high-resolution surface sediment chronology with multiple dating methods – Testing 137Cs determination with Nurmijärvi clastic-biogeni…
2017
Abstract The uppermost 50 cm of sediments from the 23 m deep lacustrine basin of Nurmijarvi, a lake in south-central Finland, are composed of the clastic-biogenic type of varves. We use multiple dating methods to render a sediment chronology that is as precise and accurate as possible for future paleoenvironmental research on this high-fidelity sedimentary archive. The 250-year-long varve chronology contains a chronological error of ±2%, as estimated based on repeated varve counts. The varve-based chronology was verified with the vertical distribution of 137Cs by comparing variations in the paleomagnetic relative declination of the surface sediments with instrumental observations and a calc…
Vidzemes muižu saimniecības sistēma: Nurmižu muižas piemērs, 1561.-1920.
2018
Nurmižu muiža kopš 18.gs beigām dažādos ceļojumu aprakstos tikusi slavināta kā muiža ar modernāko kungu namu un vienu no neparastākajiem parkiem visā Vidzemē. Tomēr pētnieciskā uzmanība tai veltīta tikai fragmentāri. Līdz šim tās vēsture aprakstīta kādas citas vēstures problēmas kontekstā. Šajā gadījumā no dažādiem aspektiem (saimniecības, sociālā vēsture, t. sk., iedzīvotāji, īpašnieku maiņa, muižas un vēlāk arī pagasta sētu saimnieciskais stāvoklis, tirdzniecība, kultūras procesi, muižas centra apbūve, ceļu infrastruktūra u.tml.), tiks aplūkota muižas izveide, attīstība un noriets. Būtisks uzsvars likts arī uz muižu kā kultūrvēsturisku pieminekli, sniedzot ieskatu muižas centra apbūves ar…

Energy efficient model for biogas production in farm scale
2011
Energy efficient solutions for six farm biogas production was found by calculating mass and energy balance in different scenarios. Raw materials in biogas production were cow manure and grass silage that were produced in these farms. There were calculated mass and energy balances on average for one year biogas prouduction that consisted of grass silage production, raw material transportation and biogas production in the biogas plant. In addition, direct greenhouse gases from biogas production were estimated. The direct mass and energy flows were calculated. It turned out that one input energy unit can produce 5.0 to 5.5 energy units as heat and electricity. Biogas reactor consumed heat from…
