Arrays in rays: terminal addition in echinoderms and its correlation with gene expression
2005
Summary The echinoderms are deuterostomes that superimpose radial symmetry upon bilateral larval morphology. Consequently, they are not the first animals that come to mind when the concepts of segmentation and terminal addition are being discussed. However, it has long been recognized that echinoderms have serial elements along their radii formed in accordance with the ocular plate rule (OPR). The OPR is a special case of terminal growth, forming elements of the ambulacra that define the rays in echinoderms. New elements are added at the terminus of the ray, which may or may not be marked by a calcified element called the terminal plate (the “ocular” of sea urchins). The OPR operates in eve…
In light of the ends. Copyright hysteresis and private copy exception after the British Academy of Songwriters, Composers and Authors (BASCA) and oth…
2015
In British Academy of Songwriters, Composers and Authors (BASCA) and others v Secretary of State for Business, Innovation and Skills, the High Court of Justice in matter of private copy exception provides the twofold prime opportunity to shed light on the state of the art of copyright in the UK and to flesh out the idea of 'legal hysteresis’. I support the reintroduction of the private copy exception, possibly in a less narrow fashion, and I explain the reasons why I am confident that my expectations will be fulfilled.
Skolebygg : påvirkes elevens prestasjoner av skolebyggets utforming?
2011
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2011 Denne oppgaven tar sikte på å estimere hvordan ulike typer skolebygg påvirker elevers læringsutbytte. Utgangspunktet for arbeidet er problemstillingen: ”Hva er effekten av ulike typer skolebygg? Påvirker utformingen av læringsarenaen elevenes prestasjoner?” For å besvare denne problemstillingen velges en kvantitativ tilnærming. Ulike skoletyper som tradisjonelle klasseromsskoler og fleksible baseskoler blir identifisert gjennom et spørreskjema som sendes ut til de utvalgte skolene. Elevers læringsutbytte måles ved et karaktergjennomsnitt som inkluderer alle avsluttende karakterer på ungdomstrinnet, grunnskolepoeng. I ana…
Analyse av fremdrift med tilhørende avvik ved Prosjekt Lyngdal Ungdomsskole : en casestudie
2013
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2013 Kostnadsoverskridelser og forsinkelser er noe vi f ar stadig inntrykk av at intre er i store byggeprosjekter. Denne masteroppgaven undersø kte et pågående prosjekt og registrerte og analyserte alle avvik i forhold til fremdriften. Det ble ogs å undersø kt hvilke metoder som ble brukt for fremdriftstyring, og hvordan dette fungerte i praksis. Planlagt ferdigstillelse av Prosjekt Lyngdal Ungdomsskole var 01/05/2013, men revidert plan indikerer en overtakelse 31/05/2013. Det er fortsatt usikkert om bygget og uteomr ådet vil væ re komplett ferdigstilt til skolestart 2013, som var overordnet m ål. Det ble totalt funnet 150 av…
Etterspørselen etter leie av næringslokaler i Kristiansand : status i dag, videre utvikling og ulikheter i forskjellige områder av byen
2009
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2009 Hensikten med denne oppgaven er å kartlegge hvordan etterspørselen etter leie av næringseiendom er i Kristiansand. Jeg har samlet inn store mengder data om temaet, og datamaterialet brukes for å teste om det er mulig å fastslå noen sammenheng mellom tidligere utarbeidede teorier og mine data. Teoriene jeg har benyttet i oppgaven er DiPasquale & Wheatons (1996) modell for analyse av utleiemarkedet for næringseiendom og Rosens (1974) hedonistiske leiepristeori. I oppgaven har jeg utformet to hypoteser. Den første hypotesen sier at en bedrifts ønskede areal avhenger av antall ansatte. Forhåndsantakelsen til denne påstanden …
Deregulation of miR-324/KISS1/kisspeptin in early ectopic pregnancy: mechanistic findings with clinical and diagnostic implications
2019
[Abstract] BACKGROUND: Ectopic pregnancy is a life-threatening condition for which novel screening tools that would enable early accurate diagnosis would improve clinical outcomes. Kisspeptins, encoded by KISS1, play an essential role in human reproduction, at least partially by regulating placental function and possibly embryo implantation. Kisspeptin levels are elevated massively in normal pregnancy and reportedly altered in various gestational pathologic diseases. Yet, the pathophysiologic role of KISS1/kisspeptin in ectopic pregnancy has not been investigated previously. OBJECTIVE: The purpose of this study was to evaluate changes of KISS1/kisspeptin levels in ectopic pregnancy and thei…
How does eating in the absence of hunger in children relate to child's BMI, inhibitory control and to maternal controlling feeding practices?
2021
International audience; Young children have an innate ability to self-regulate their food-intake by following their inner sensations of hunger and satiation. Children's temperamental traits and environmental factors, such as controlling feeding practices, can alter their self-regulation abilities and can induce weight gain in the long-term. The current study aimed to study how young children's eating in the absence of hunger (EAH) is related to their level of inhibitory control, body mass index (BMI) and maternal controlling feeding practices (food as reward, restriction for health, restriction for weight control). Mothers of 621 French children aged 2.00-6.97 years (51% boys, M = 4.11 year…
Resistance to the Bacillus thuringiensis bioinsecticide in a field population of Plutella xylostella is due to a change in a midgut membrane receptor.
1991
The biochemical mechanism for resistance to Bacillus thuringiensis crystal proteins was studied in a field population of diamondback moths (Plutella xylostella) with a reduced susceptibility to the bioinsecticidal spray. The toxicity and binding characteristics of three crystal proteins [CryIA(b), CryIB, and CryIC] were compared between the field population and a laboratory strain. The field population proved resistant (greater than 200-fold compared with the laboratory strain) to CryIA(b), one of the crystal proteins in the insecticidal formulation. Binding studies showed that the two strains differ in a membrane receptor that recognizes CryIA(b). This crystal protein did not bind to the b…
Top-down effects of a lytic bacteriophage and protozoa on bacteria in aqueous and biofilm phases
2014
Lytic bacteriophages and protozoan predators are the major causes of bacterial mortality in natural microbial communities, which also makes them potential candidates for biological control of bacterial pathogens. However, little is known about the relative impact of bacteriophages and protozoa on the dynamics of bacterial biomass in aqueous and biofilm phases. Here, we studied the temporal and spatial dynamics of bacterial biomass in a microcosm experiment where opportunistic pathogenic bacteria Serratia marcescens was exposed to particle‐feeding ciliates, surface‐feeding amoebas, and lytic bacteriophages for 8 weeks, ca. 1300 generations. We found that ciliates were the most efficient enem…
Downregulation of a Chitin Deacetylase-Like Protein in Response to Baculovirus Infection and Its Application for Improving Baculovirus Infectivity
2009
ABSTRACT Several expressed sequence tags (ESTs) with homology to chitin deacetylase-like protein (CDA) were selected from a group of Helicoverpa armigera genes whose expression changed after infection with H. armigera single nucleopolyhedrovirus (HearNPV). Some of these ESTs coded for a midgut protein containing a chitin deacetylase domain (CDAD). The expressed protein, HaCDA5a, did not show chitin deacetylase activity, but it showed a strong affinity for binding to chitin. Sequence analysis showed the lack of any chitin binding domain, described for all currently known peritrophic membrane (PM) proteins. HaCDA5a has previously been detected in the H. armigera PM. Such localization, togethe…
