Feed intake and weight and body condition changes of 100% organically fed lactating sows

Energy and protein density of the 100 % organic lactation diet should be increased as early as from 3rd week of lactation onwards in order to minimize the weight loss of the sow during the at least 40 day lactation period. Feed amino acid balance from 22nd day of lactation should match the amount of live weight lost during the first 21 days of lactation. This should be supported by providing the piglets feed attractive enough to ensure their high dry feed intake during the late lactation period

Genetic uniqueness and socio-cultural conservation values of the endangered Yakutian Cattle

At the local level the values of the cattle were more related to everyday livelihood strategies of single households and families, whereas the representatives of the republic, in line with the newspapers, highlighted the importance of the cattle for Sakha's food production and for national identity. Thus, individuals at different levels were in favour of conserving the cattle, but for different reasons. The local residents and experts were more concerned about developing economically sustainable cattle production, whereas the experts in Yakutsk were concerned about the conservation of genetic resources. The genetic studies have indicated that Yakutian Cattle show genetic distinctiveness and have genetic value for the maintenance of cattle diversity

Valence electronic structure and photofragmentation of 1,1,1,2-tetrafluoroethane (CF3-CH2F)

The electronic structure and fragmentation of the hydrofluorocarbon compound 1,1,1,2-tetrafluoroethane (CF3-CH2F) were studied using spectroscopical methods and quantum chemical calculations. Valence photoelectron spectra and the ionic fragmentation products were recorded with synchrotron radiation in the vacuum ultraviolet (VUV) region. The geometric and electronic structures of the CF3-CH2F molecule were calculated using the complete active space perturbation theory of second order. The calculated vertical ionization energies were used to interpret the experimental photoelectron spectrum. VUV photodissociation of the sample molecule was studied with photoelectron-photoion coincidence spectroscopy. Coincident ion yields are shown for several cations as a function of electron binding energy. The experimental data are discussed in comparison with theory and previous work

Kirjallisuuskasvatuksen merkityksiä varhaiskasvatuksen opettajien tulkitsemana esiopetuksessa

Tiivistelmä. Tutkimuksen tarkoituksena on selvittää kirjallisuuskasvatuksen merkityksiä varhaiskasvatuksen opettajien tulkitsemana esiopetuksessa. Päätutkimuskysymykseksi muodostui: ”mikä on kirjallisuuskasvatuksen merkitys varhaiskasvatuksen opettajan näkökulmasta?” Lisäksi tutkimus jäsentyi seuraavien alatutkimuskysymyksien kautta: ”minkälaista kirjallisuuskasvatusmateriaalia varhaiskasvatuksen opettajat hyödyntävät esiopetuksen arjessa? ja ”millaisia merkityksiä kirjallisuuskasvatuksella on varhaiskasvatuksien opettajien tulkintojen mukaan lapsen kehitykselle ja oppimiselle?” Tutkimus on toteutettu mixed methods -lähestymistavalla, joka yhdistää laadullisen ja määrällisen metodologian. Määrällinen aineisto kerättiin kyselylomakkeella, johon saatiin vastaus 28 varhaiskasvatuksen opettajalta. Tämän lisäksi haastateltiin viittä varhaiskasvatuksen opettajaa. Aineiston analyysi tapahtui teoriaohjaavan sisällönanalyysin avulla. Teoria rakentuu ydinkäsitteen kirjallisuuskasvatus ympärille, jossa painottuu erityisesti pedagoginen käyttö sekä opettajan ja lapsen välinen vuorovaikutus. Otamme tutkimuksessa huomioon myös esiopetusta ohjaavat asiakirjat kirjallisuuskasvatuksen näkökulmasta. Esimerkiksi Esiopetuksen opetussuunnitelman perusteissa (2014) monilukutaito liittyy kiinteästi ajattelun ja oppimisen taitoihin. Jotta nämä taidot kehittyvät, lapsi tarvitsee avukseen opettajan lukemisen mallia ja rikasta tekstiympäristöä, jonka kirjallisuuskasvatuksen käyttö voi parhaimmillaan tarjota. Kirjallisuuskasvatuksen käsitettä ei kuitenkaan suoraan mainita kyseisessä asiakirjassa, joka voi osittain vaikuttaa tuloksissa esiin nousseeseen käsitteen vierauteen, vaikka sen merkitys koettiinkin vahvana. Kirjallisuuskasvatuksen käyttöä haastaa tulosten mukaan lasten vähentynyt kiinnostunut lukemista ja kirjallisuutta kohtaan. Tutkimustuloksista kuitenkin ilmenee, että kirjallisuuskasvatuksella katsotaan olevan tärkeä merkitys esiopetuksessa ja sitä käytetään monipuolisesti, säännöllisesti sekä pedagogisesti; lisätietoisuutta, materiaalia sekä koulutusta tulisi kuitenkin olla tarjolla enemmän

Parity nonconserving cold neutron-parahydrogen interactions

Three pion dominated observables of the parity nonconserving interactions between the cold neutrons and parahydrogen are calculated. The transversely polarized neutron spin rotation, unpolarized neutron longitudinal polarization, and photon-asymmetry of the radiative polarized neutron capture are considered. For the numerical evaluation of the observables, the strong interactions are taken into account by the Reid93 potential and the parity nonconserving interactions by the DDH model along with the two-pion exchange.Comment: 17 pages, 2 figure

Dissociative photoionization of the NO molecule studied by photoelectron-photon coincidence technique

Low-energy photoelectron–vacuum ultraviolet (VUV) photon coincidences have been measured using synchrotron radiation excitation in the inner-valence region of the nitric oxide molecule. The capabilities of the coincidence set-up were demonstrated by detecting the 2s−1 → 2p−1 radiative transitions in coincidence with the 2s photoelectron emission in Ne. In NO, the observed coincidence events are attributed to dissociative photoionization with excitation, whereby photoelectron emission is followed by fragmentation of excited NO+ ions into O+ + N* or N+ + O* and VUV emission from an excited neutral fragment. The highest coincidence rate occurs with the opening of ionization channels which are due to correlation satellites of the 3σ photoionization. The decay time of VUV photon emission was also measured, implying that specific excited states of N atoms contribute significantly to observed VUV emission

Dynamic Analysis of Vascular Morphogenesis Using Transgenic Quail Embryos

Background: One of the least understood and most central questions confronting biologists is how initially simple clusters or sheet-like cell collectives can assemble into highly complex three-dimensional functional tissues and organs. Due to the limits of oxygen diffusion, blood vessels are an essential and ubiquitous presence in all amniote tissues and organs. Vasculogenesis, the de novo self-assembly of endothelial cell (EC) precursors into endothelial tubes, is the first step in blood vessel formation [1]. Static imaging and in vitro models are wholly inadequate to capture many aspects of vascular pattern formation in vivo, because vasculogenesis involves dynamic changes of the endothelial cells and of the forming blood vessels, in an embryo that is changing size and shape. Methodology/Principal Findings: We have generated Tie1 transgenic quail lines Tg(tie1:H2B-eYFP) that express H2B-eYFP in all of their endothelial cells which permit investigations into early embryonic vascular morphogenesis with unprecedented clarity and insight. By combining the power of molecular genetics with the elegance of dynamic imaging, we follow the precise patterning of endothelial cells in space and time. We show that during vasculogenesis within the vascular plexus, ECs move independently to form the rudiments of blood vessels, all while collectively moving with gastrulating tissues that flow toward the embryo midline. The aortae are a composite of somatic derived ECs forming its dorsal regions and the splanchnic derived ECs forming its ventral region. The ECs in the dorsal regions of the forming aortae exhibit variable mediolateral motions as they move rostrally; those in more ventral regions show significant lateral-to-medial movement as they course rostrally. Conclusions/Significance: The present results offer a powerful approach to the major challenge of studying the relative role(s) of the mechanical, molecular, and cellular mechanisms of vascular development. In past studies, the advantages of the molecular genetic tools available in mouse were counterbalanced by the limited experimental accessibility needed for imaging and perturbation studies. Avian embryos provide the needed accessibility, but few genetic resources. The creation of transgenic quail with labeled endothelia builds upon the important roles that avian embryos have played in previous studies of vascular development

Parity nonconservation in deuteron photoreactions

We calculate the asymmetries in parity nonconserving deuteron photodisintegration due to circularly polarized photons gamma+d to n+p with the photon laboratory energy ranging from the threshold up to 10 MeV and the radiative capture of thermal polarized neutrons by protons n+p to gamma+d. We use the leading order electromagnetic Hamiltonian neglecting the smaller nuclear exchange currents. Comparative calculations are done by using the Reid93 and Argonne v18 potentials for the strong interaction and the DDH and FCDH "best" values for the weak couplings in a weak one-meson exchange potential. A weak NDelta transition potential is used to incorporate also the Delta(1232)-isobar excitation in the coupled-channels formalism.Comment: 14 pages, 13 figures (18 eps files), LaTeX2
