Service Check on Pig and Cattle Farms - Establish the Visions

A service check for a farm is an interesting new way of advising farmers, which has proven very successful. The objective of a service check is to recognise potential improvements in the production using a holistic approach. Often a service check will try to establish the overall goals for the farmer’s family, the farmer and the farm. In order to do so, the farm is systematically analysed in order to establish strengths, weaknesses and possible paths of development. These issues are normally neglected in the day-today contact between the farmer and the usual adviser, and even far-reaching decisions are often taken without a decent analysis of the strategic goals. A service check involves a joint visit, where two experienced advisors visit the farm together. The advisors are normally an economic advisor and either a pig or cattle advisor, depending on the farm analysed. Usually, the farm’s normal advisors are not participating in the service check. The advisors bring an analysis of the economic and productivity data, and are presented to the farm. A normal service check will produce a report stating the current status, plans for the future and appointments for more specific advisory work that have been agreed upon. Despite the price of a service check, the product has been successful. Farmers achieve a better perspective of the strategic possibilities and limitations of their farm, and it becomes possible to establish realistic long-term goals for the farm development. The clarity improves the farmer’s self-confidence and the pleasure of work. Advisors are also satisfied, since the farmer will often initiate new projects after the service check, which in turn increases the demand for advisory services.Farm Management,

Faremarksmanual

Faremarksmanualen henvender sig til personer, der har ansvaret for – eller arbejder i faremarken. Faremarksmanualen er en vejledning til at opnå det bedst mulige produktionsresultat. Manualen omhandler perioden fra etablering af farefolden til fravænning af pattegrisene. Beskrivelser og anvisninger i manualen er baseret på forskningsresultater, lærebøger og erfaringer

Økologisk svineproduktions miljøpåvirkning

Beslutningsstøtte model til estimering af miljøpåvirkninger på bedriftsnivea

Økologisk svineproduktions miljøpåvirkninger. Beslutningsstøttemodel til estimering af miljøpåvirkninger på bedriftsniveau. Model + Brugermanual

Modellen gør det muligt for producenter og rådgivere at estimere den enkelte besætnings miljøpåvirkninger, på baggrund af bedriftens egne data, og giver hermed et bedre grundlag end i dag, for også at inddrage de miljømæssige effekter i diskussionen, f.eks. når en ny besætning skal startes op

Observation of interlayer phonon modes in van der Waals heterostructures

We have investigated the vibrational properties of van der Waals heterostructures of monolayer transition metal dichalcogenides (TMDs), specifically MoS2/WSe2 and MoSe2/MoS2 heterobilayers as well as twisted MoS2 bilayers, by means of ultralow-frequency Raman spectroscopy. We discovered Raman features (at 30 ~ 40 cm-1) that arise from the layer-breathing mode (LBM) vibrations between the two incommensurate TMD monolayers in these structures. The LBM Raman intensity correlates strongly with the suppression of photoluminescence that arises from interlayer charge transfer. The LBM is generated only in bilayer areas with direct layer-layer contact and atomically clean interface. Its frequency also evolves systematically with the relative orientation between of the two layers. Our research demonstrates that LBM can serve as a sensitive probe to the interface environment and interlayer interactions in van der Waals materials

The time delay of the quadruple quasar RX J0911.4+0551

We present optical lightcurves of the gravitationally lensed components A (=A1+A2+A3) and B of the quadruple quasar RX J0911.4+0551 (z = 2.80). The observations were primarily obtained at the Nordic Optical Telescope between 1997 March and 2001 April and consist of 74 I-band data points for each component. The data allow the measurement of a time delay of 146 +- 8 days (2 sigma) between A and B, with B as the leading component. This value is significantly shorter than that predicted from simple models and indicates a very large external shear. Mass models including the main lens galaxy and the surrounding massive cluster of galaxies at z = 0.77, responsible for the external shear, yield H_0 = 71 +- 4 (random, 2 sigma) +- 8 (systematic) km/s/Mpc. The systematic model uncertainty is governed by the surface-mass density (convergence) at the location of the multiple images.Comment: 12 pages, 3 figures, ApJL, in press (June 20, 2002
