Helge S. Kragh, Conceptions of Cosmos [Book Review]
No full textHelge S. Kragh, historian of science and prolific author of books (and a member of the editorial board
of this journal), has given us nothing less than a thorough history of cosmology, from biblical myths to
the present view of accelerated expansion. It’s a noble thing to try, and even if it isn’t always perfectly
accurate, Conceptions of Cosmos makes a real contribution to the literature
I remember life as an Estonian at Seabrook
No full textIn this "I remember" memoir, Helge Kangur recalls her Estonian upbringing at Seabrook. She realizes now how fortunate she was to grow up in such a diverse community. The Seabrook Educational and Cultural Center has been soliciting current and past residents of Seabrook Farms for an "I remember" project. Residents are asked to create narratives regarding their experiences at Seabrook Farms. These memories help preserve the history and multi-cultural heritage of Seabrook Farms
Renaissancen og middelalderen som periodiseringsbegreber:et essay
No full textThe essay discusses the traditional and the occasionally exaggerated use of periodisations in general historical studies. The terms 'the Middle Ages' and 'the Renaissance' have had very long and complicated histories of their own. Of the two terms "the Middle Ages", which was originally a pejorative expression, has appeared to be the strongest of the two, whereas the term 'the Renaissance' has had a much more chaotic history in historiography. During the last 150 years of historical writing and thinking it has gone from the highest success (due to Burchardt 1861) to the deepest downfall (around 1930). The author argues for the preservation of the term 'the Renaissance' for three reasons: (1) The period of the Renaissance coincides with the emergence of the modern, strong power state (from the 14th and 15th centuries onwards) in contrast to the medieval, decentralized, feudal political system, (2) the break-through of the secularisation of science, the humanities, culture and art (during the 15th and 16th centuries), and not in the least (3) the new consciousness of history (the here and now concept!), which arose in Italy in the 15th century, and which broke the millennial, traditional Christian explanation of the course of history
Estimating yearly numbers of animals, and enteric methane emissions, for pigs. Methodologies for the Norwegian national inventory of GHG emissions
No full textCommissioned by the Norwegian Environment Agency, this report presents methodologies for estimating annual numbers of animals and enteric methane emissions for pigs. The methodologies are designed for the Norwegian national inventory of GHG emissions (NIR) and are dynamic, reflecting the effects of progress in genetics and management of the pork production. The data sources for the proposed methodologies are the register for deliveries of carcasses to Norwegian slaughterhouses available from Statistics Norway, and the Norwegian litter recording system (Ingris) of the Norwegian meat and poultry research centre (Animalia)
Karbon i norsk plante- og husdyrproduksjon
No full textBeregnet karbondioksid (CO2) omdannet til organisk materiale av planter tilknyttet norsk jordbruksproduksjon var i 2005 mer enn 10 Mt. Vegen karbon tar fra CO2 i atmosfæren via organisk stoff og tilbake til CO2 varierer i forhold til hvilke jordbruksplanter som binder CO2 og hvordan plantene anvendes i matproduksjonskjeden. I dette notatet presenteres en grov kvantifisering av karbonstrømmen for ulike produksjonssystemer i norsk jordbruk. Vi presenterer også en svært grov beregning av den historiske utviklingen i karbonstrømmene i norsk jordbruk. Data om produksjonssystemene er hovedsakelig hentet fra Budsjettnemnda for jordbruket (BFJ), Statens landbruksforvaltning (SLF), Statistisk sentralbyrå (SSB), Driftsgranskinger i jord- og skogbruk (NILF), Handbok for driftsplanlegging (NILF), K. K. Heje, Håndbok for jordbruket (Heje, 1998) og TINE Norske Meierier (TINE). Karboninnholdet i planter, både til mat og fôr, og i husdyrprodukter ble beregnet ved hjelp av metodikk utviklet i Japan. Karboninnholdet i husdyrgjødsla ble beregnet med utgangspunkt i amerikanske tall for mengde per dyr, tørrstoffprosent, nitrogenprosent og C/N forhold. Svært grove tall for karbontap i husdyras respirasjon ble fastsatt med basis i rapporten Livestock's Long Shadow. Metantap fra tarm og vom fra husdyr samt metanproduksjon i husdyrgjødsel ble beregnet etter SSB sitt klimaregnskap. Årlig produksjon av planteresidualer (røtter, stubb, halm) er beregnet ved hjelp av koeffisienter fra IPCC, Swedish Environmental Protection Agency og Umweltbundesamt. Hovedkategoriene i norsk planteproduksjon er grasmark (flerårig) og åkerbruk (ettårig). Det var 6 549 800 daa grasmark og 3 631 747 daa åkerland i Norge i 2005 (tabell 3.1). Økonomisk avling var 2 741 000 tonn tørrstoff (t TS) for grasmark, i tillegg kommer utmarks- og fjellbeite, og 1 204 000 tonn TS for åkervekster. Planteresidualer ble anslått til å være 807 000 tonn TS i grasmark (røtter og stubb) og 1 424 000 tonn TS for åkervekstene (røtter, stubb og halm). Bare noe i underkant av 10 prosent av økonomisk planteproduksjonsavling gikk i 2005 direkte til menneskemat. I alt 910 000 t kraftfôr ble i 2005 gitt til drøvtyggere, det tilsvarer noe mer enn halvparten av den totale kraftfôrmengden til husdyrholdet i 2005. Den vesentligste delen av karbonstrømmen fra norsk planteproduksjon er derfor kanalisert til drøvtyggerne. Produksjonssystemenes evne til å omsette bundet karbon til produkter er ulik, og den andel av karbon som ikke finnes igjen i produkter eller tapes i ånding og metan, er også ulik. Drøvtyggersystemene tilførte i 2005 vesentlig mer karbon til jorda enn svin- og fjørfeproduksjonssystemene. I tillegg vil røtter og stubb fra grasmark være levende, slik at evnen til bygge opp og vedlikeholde en høy karbontilstand i jord vil være høyere for et grasmark - drøvtyggersystem enn et åker - lystkjøttsystem. Størrelsene på tilført karbon i avling og bortført karbon ble ikke like for 2005, det er verdt å merke seg at alle tall er estimerte størrelser beheftet med stor usikkerhet. […]publishedVersio
The effects of progress in genetics and management on intensities of greenhouse gas emissions from Norwegian pork production
No full textThe environmental sustainability of food production systems, including net greenhouse gas (GHG) emissions, is of increasing importance. In Norwegian pork production, animal performance is high in terms of reproduction, growth, and health. The development and use of an IPCC methodology-based model for estimating GHG emissions from pork production could be helpful in identifying the effects of progress in genetics and management. The objective was to investigate whether an IPCC methodology-based model was able to reflect the effects of the progress in genetics and management in pork production on the GHG emissions per kg carcass weight (CW). It is hypothesized that this progress has led to low GHG emissions intensities in Norwegian pork compared to global levels and that expected improvements will give a lasting reduction in GHG emissions intensities. A model ‘HolosNorPork’ for estimating net farm gate GHG emissions intensities was developed, including allocation procedures, at the pig production unit level. The model was run with pig production data from in average 632 farms from 2014 to 2019. The estimates include emissions of enteric and manure storage methane, manure storage nitrous oxide emissions, as well as GHG emissions from production and transportation of purchased feeds, and direct and indirect GHG emissions caused by energy use in pig-barns. The model was able to estimate the effects on net GHG emissions intensities from pork production on the basis of production characteristics. The estimated net GHG emissions intensity was found to have decreased from on average 2.49 to 2.34 kg CO2 eq. kg−1 CW over the investigated period. For 2019 the net GHG emission for the one-third lower performing farms was estimated to 2.56 kg CO2 eq. kg−1 CW, whereas for the one-third medium and one-third best performing farms the estimates were 2.36 and 2.16 kg CO2 eq. kg−1 CW, respectively. The net GHG emissions intensity for pork carcasses from boars was estimated to be 2.07 kg CO2 eq. kg−1 CW. For the health regimes investigated, Conventional and Specific-Pathogen Free (SPF), the estimated GHG emissions intensities for 2019 were 2.37 and 2.24 kg CO2 eq. kg−1 CW, respectively. The effects on net GHG emissions intensities of breeding and management measures were estimated to be profound, and this progress in pig production systems contributes to an on-going strengthening of pork as a sustainable source for human food supply
