Secondary implant stability outcome of immediate versus late placed variable-thread implants in the maxilla. A retrospective cohort study

2017

BACKGROUND The healing of xenograft augmentated intra-alveolar gaps following immediate implant placement (IMIP) after tooth extraction is likely to differ in time and density compared to the native bone part that directly contacts the implant. MATERIAL AND METHODS Secondary implant stability (SIS) data recorded 2-3 months following a late implant placement protocol (LIP) (n= 43) and 6-8 months following an immediate implant placement protocol (IMIP) (n=33) of variable-thread implants (Nobel Active™) in the maxilla were retrospectively collected from files of 63 patients (42 females, 21 males). Statistical analysis was performed using a generalized estimating equation model (GEE). Data spli…

Investigation of the Electromagnetic Radiation Emitted by Sub-GeV Electrons in a Bent Crystal.

2015

The radiation emitted by 855 MeV electrons via planar channeling and volume reflection in a $30.5\text{\ensuremath{-}}\ensuremath{\mu}\mathrm{m}$-thick bent Si crystal has been investigated at the MAMI (Mainzer Mikrotron) accelerator. The spectral intensity was much more intense than for an equivalent amorphous material, and peaked in the MeV range in the case of channeling radiation. Differently from a straight crystal, also for an incidence angle larger than the Lindhard angle, the spectral intensity remains nearly as high as for channeling. This is due to volume reflection, for which the intensity remains high at a large incidence angle over the whole angular acceptance, which is equal t…

Annengjøring av homoseksualitet : en studie av seksualundervisning i norsk skole

2019

Masteroppgave samfunnskunnskap SV505 - Universitetet i Agder 2019 I denne oppgaven prøver jeg å besvare følgende problemstilling: Hvordan gjør lærere seksualundervisning? I hvilken grad er deres seksualundervisning med på å annengjøre homofili og hvordan kan homofili normaliseres? Min empiri har jeg tilegnet meg gjennom intervjuer med fire personer som tidligere har vært elever vedgrunnskole og videregående skolei Norge. Spørsmålene dreide seg i hovedsak om hvordan mine informanters lærere gjorde seksualundervisning, hvordan homofili eventuelt ble inkludert ellertvert omekskludert i undervisningen, og hva mine informanter mente kunne forbedre seksualundervisning og gjøre den mindre heterono…

Deltidsarbeidende menn på Sørlandet : en studie av mannlige deltidsarbeideres begrunnelser for, og opplevelser av, deltidsarbeid på Sørlandet

2019

Masteroppgave samfunnskunnskap SV505 - Universitetet i Agder 2019 Formålet med denne oppgaven er å få innsikt i mannlige deltidsarbeideresbegrunnelser for, og opplevelser av, deltidsarbeid på Sørlandet. Studien har etkvalitativ designog er basert på intervjuer med fem deltidsarbeidende menn.Hensikten med studien erå frembringe ny kunnskap om hvordan mennpå Sørlandet opplever å arbeide deltid i en landsdel som er sterkt preget av kvinner i deltidsstillinger,og som skårer lavt på mål omlikestilling. Jeg har anvendtkjønnsteoretiske perspektiver i analysen avmaterialet og diskuterer funnene opp mot teorier om kjønn som gjøren og forhandling. I tilleggdiskuteresfunnene opp mot individualiserings…

Kvinnenettverk i næringslivet: Business as usual? : En kvantitativ studie om kvinners erfaringer med nettverket «Women in Business» i Kristiansand

2020

Master's thesis in Social science (SV505) I denne studien er det undersøkt hvordan medlemmer av nettverket Women in Business opplever deltakelse i dette, samt hvordan de opplever likestillingssituasjonen på deres egne arbeidsplasser. Det er også spurt etter kvinnenes holdninger til likestilling generelt. Studien har fått tittelen «Kvinnenettverk i næringslivet: Business as usual?», som reflekterer temaets aktualitet og navnet på nettverket som undersøkes. Oppgavens problemstilling er todelt, og har spurt etter i) «Hvordan opplever kvinner som deltar i nettverket «Women in Business» likestillingssituasjonen på sine arbeidsplasser, og deltakelse i dette nettverket?», og ii) «Hvordan kan disse…

Recruitment of Xrn1 to stress-induced genes allows efficient transcription by controlling RNA polymerase II backtracking

2020

A new paradigm has emerged proposing that the crosstalk between nuclear transcription and cytoplasmic mRNA stability keeps robust mRNA levels in cells under steady-state conditions. A key piece in this crosstalk is the highly conserved 5′–3′ RNA exonuclease Xrn1, which degrades most cytoplasmic mRNAs but also associates with nuclear chromatin to activate transcription by not well-understood mechanisms. Here, we investigated the role of Xrn1 in the transcriptional response of Saccharomyces cerevisiae cells to osmotic stress. We show that a lack of Xrn1 results in much lower transcriptional induction of the upregulated genes but in similar high levels of their transcripts because of parallel …

Rpb4 and Puf3 imprint and post-transcriptionally control the stability of a common set of mRNAs in yeast

2020

ABSTRACTGene expression involving RNA polymerase II is regulated by the concerted interplay between mRNA synthesis and degradation, crosstalk in which mRNA decay machinery and transcription machinery respectively impact transcription and mRNA stability. Rpb4, and likely dimer Rpb4/7, seem the central components of the RNA pol II governing these processes. In this work we unravel the molecular mechanisms participated by Rpb4 that mediate the posttranscriptional events regulating mRNA imprinting and stability. By RIP-Seq, we analyzed genome-wide the association of Rpb4 with mRNAs and demonstrated that it targeted a large population of more than 1400 transcripts. A group of these mRNAs was als…

The total mRNA concentration buffering system in yeast is global rather than gene-specific

2021

Gene expression in eukaryotes does not follow a linear process from transcription to translation and mRNA degradation. Instead it follows a circular process in which cytoplasmic mRNA decay crosstalks with nuclear transcription. In many instances, this crosstalk contributes to buffer mRNA at a roughly constant concentration. Whether the mRNA buffering concept operates on the total mRNA concentration or at the gene-specific level, and if the mechanism to do so is a global or a specific one, remain unknown. Here we assessed changes in mRNA concentrations and their synthesis rates along the transcriptome of aneuploid strains of the yeast Saccharomyces cerevisiae. We also assessed mRNA concentra…

Differential cross section for the reaction 2H(γ, p)n from 133 to 158 MeV

1991

The cross section for the reaction 2H(γ, p)n has been measured at laboratory photon energies Eγ = 133−158 MeV and c.m. angles between 30° and 150°. The reaction was induced by a tagged bremsstrahlung photon beam incident on a liquid deuterium target. The uncertainty in the absolute cross sections is ⩽ 5%. There is now reasonable agreement between recent measurements in this energy region and the overall data set now defines the cross section sufficiently well to provide a test of current models of the reaction.
