Rautakauden muinaisjäännökset Kanta-Hämeessä Paikkatietoaineistojen analyysi
Tutkielmassa on tehty paikkatietoanalyysi Kanta-Hämeen varhaismetallikautisille ja rautakautisille kiinteille muinaisjäännöksille. Keskeisiä kysymyksiä tutkielmassa ovat eriaikaisten ja -tyyppisten muinaisjäännösten yhteys vesistöihin ja pintamaan maalajeihin. Muita analysoituja muuttujia ovat maanpinnan kaltevuus muinaisjäännöspisteissä, kyseisen rinteen ilmansuunta ja paikalle säteilevä vuotuinen auringon säteilyenergia. Tutkielmassa on analysoitu vastaavilla muuttujilla myös Kanta-Hämeestä tunnettuja muinaispeltoja.
Tutkielmassa käydään myös lyhyesti läpi Kanta-Hämeen rautakauden elinkeinoista kertovat siitepölyanalyysit, viljelykasvien makrofossiilit ja analysoidut osteologiset aineistot.
Analyysien tulosten perusteella laadittiin ennustava malli rautakauden asutukselle Kanta-Hämeessä soveltuneista alueista.
Analyysin tulokset tukevat jo aiemmin rautakauden asutuksen levinneisyydestä saatua kuvaa, jossa asutus on keskittynyt alueille, joilla on paljon hiesua ja hietoja pintamaassa. Keskittyminen näille varhaiselle maanviljelykseen soveltuneille alueille näyttäisi Kanta-Hämeessä alkavan jo varhaismetallikaudella. Ristiretkiajalla asutus keskittyy aiempaa enemmän savimaiden läheisyyteen. Rautakauden kuluessa asutus vaikuttaisi etääntyvän hieman vesistöistä.Siirretty Doriast
History and Use of Wood Pyrolysis Liquids as Biocide and Plant Protection ProductHistory and Use of Wood Pyrolysis Liquids as Biocide and Plant Protection Product
Archeological studies have found that pyrolysis liquids were already used in the time of the Neanderthal. Wood
vinegar and other slow pyrolysis liquids are produced as a by-product of charcoal production. However, future business
ideas may be the other way round as pyrolysis liquids may replace synthetic chemicals in the form of pesticides and
biocides.
Directives and regulations related to the sustainable use of pesticides govern and direct plant protection strategies towards
a lower use of synthetic chemicals. It is hoped that many mega trends of global policies will boost the use of plant based
products given that a reduced reliance on fossil fuel is a general target in the global food and feed production economy.
Pyrolysis technology has been actively studied and developed around the world and is linked to the development of the
knowledge based bio-economy. The importance and social impact of pyrolysis technologies will also be enhanced
because it is a practicable technique in the sustainable use of wastes and biomasses. However, very little scientific evidence
is available to support efficacy claims of wood vinegar and toxicology assessments of the products used. Wood tar
has been investigated a bit more thoroughly. The aim of this review was to clarify the potential of slow pyrolysis liquids
in agricultural use, in particular, in pesticide applications. In addition, some of the main challenges in developing novel
bio control technologies are discussed and the barriers in the commercialization of biological control agents are revealed.</jats:p
Archaeological Artefact Database of Finland (AADA)
<p>When you use this dataset, please also cite the following paper introducing it:</p>
<p>Petro Pesonen, Ulla Moilanen, Meeli Roose, Jarkko Saipio, Jasse Tiilikkala, Muhammad Usman Sanwal, Visa Immonen, Outi Vesakoski & Päivi Onkamo (submitted manuscript): Archaeological Artefact Database of Finland (AADA).</p>
<p>The database also includes a collection of photographs that are found in another Zenodo repository and should be referenced as follows: Moilanen et al. 2024. (Moilanen, U., Pesonen, P., Saipio, J., Tiilikkala, J., Sanwal, M. 2024. Archaeological Artefact Database of Finland (AADA)), photograph repository: https://zenodo.org/records/10417384</p>
<p>The AADA database is thematically organised into three MS Excel tables according to the prehistoric era: Stone Age, Bronze Age, and Iron Age periods. Each period contains both period-specific and general artefact categories and accordingly also period-specific and general variables(Table 1). The database is provided also as csv-files.</p>

<p>Each row in the table represents a single artefact, while each column represents a specific attribute, such as its type, period, site, and measurements. Pottery forms a different case as the material is not organised according to separate vessels (except pottery detailed in AADA Iron Age), but according to types/styles present in each collection main number. The detailed description of the data is found in the paper Pesonen et al. (2024).</p>
