Popular Abstract in Swedish ECL celler är endokrina (peptid-hormon-producerande) celler belägna i magsäckens syra-producerande del (fundus). Cellerna är av stor betydelse vid regleringen av magens saltsyra produktion och sekretion eftersom de innehåller histamin. Frisatt histamin aktiverar intilliggande parietal celler att utsöndra saltsyra. ECL cellen innehåller också polypeptiden chromogranin A ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They are important regulators of gastric acid secretion in the stomach by virtue of their histamine synthesizing and secreting capacity. Histamine in turn stimulates parietal cells to secrete acid. The ECL cell also contains the endocrine polypeptide chromogranin A (CGA) and CGA-derived peptides such as panc

Popular Abstract in Swedish Det romerska triumftåget var en segerprocession som paraderade in i och genom staden Rom efter varje segerrikt fälttåg. I tåget leddes byten och fångar av många olika slag samt avbildningar av erövrade platser och folkslag som tillverkats för processionen. Avhandlingen analyserar dessa uttryck för ”den andre” och diskuterar hur triumftåget både reflekterade och skapade The triumphal procession staged Roman conquest and supremacy, featuring the defeated ‘other’ as opposed to the victorious ‘self’ in a rather fixed role-playing. This thesis takes as its theoretical premise that these ritually recurrent and visually emphatic processions both conveyed and constructed Roman views of the self and the other, and that they can be studied as formative expressions of such

Popular Abstract in Swedish Populärvetenskaplig svensk sammanfattning Har allvarliga infektioner orsakade av bakterien Haemophilus influenzae försvunnit? En undertyp av H. influenzae, typ b (Hib), var tidigare en fruktad orsak till struplocksinflammation, hjärnhinneinflammation och svår blodförgiftning hos små barn. Problemet var så stort att allmän vaccination mot Hib infördes i många länder i böWhat is the current status of Haemophilus influenzae as an agent of invasive infection in Sweden? H. influenzae type b (Hib) used to be a common cause of meningitis, epiglottitis and severe sepsis in young children. In the late 1980’s an effective conjugated vaccine against Hib was developed and a dramatic fall in Hib incidence was observed in countries that implemented vaccination. This includes

Denna avhandling undersöker retorisk flertydighet som en egenskap hos uttryck som adresserar sammansatta, heterogena publiker. Avhandlingens syfte är att utveckla konceptuella verktyg för analysen av flertydiga kommunikativa handlingar, för att undersöka vilka utfall de kan möjliggöra. Avhandlingens utgångspunkt är att uttryck är meningsfulla och fundamentalt sociala handlingar, som alltid är en dThis thesis is an inquiry into rhetorical ambiguity as a property of utterances addressing composite, heterogeneous audiences. The purpose is to develop conceptual tools to analyse ambiguous communicative acts for the outcomes they make possible. The thesis proceeds from the assumption that utterances are purposeful and fundamentally social acts, always part of an ongoing social dialogue. As such,

Badgästerna vill ha möjlighet till olika alternativ på aktiviteter och service under ett och samma tak. Klimatet i badhuset måste därför anpassas så att detta blir möjligt. Erfarenheten har visat att denna utveckling lett till ett antal tekniska problem som måste lösas. Produktionserfarenheten fr

Populärvetenskaplig sammanfattning: Conodonter är stratigrafiskt användbara, fosfatiska mikrofossil, som påträffas i marina sediment mellan senkambrium till slutet av trias (520-210 Ma). Olika formtyper av conodonter, eller conodontelement, byggde tillsammans upp käkapparaten hos det lilla ål-liknande conodontdjuret, som numera räknas till chordaterna. Jag har undersökt förekomsten av conodontsläkSeven taxa of the conodont genus Ctenognathodus (Fay, 1959) sensu Viira, 1982b in the Silurian of Gotland have been described and their occurrence mapped geographically, stratigraphically and related to facies. In addition to C. murchisoni (Pander, 1856) three new species were found; C. n. sp. D, C n. sp. E and C n. sp. I with two subspecies, I and G. Two taxa formerly known as subspecies of Ligon

Uppsatsen tar sikte på att behandla sak- och associationsrättsliga aspekter inom ramen för en aktietransaktion, i synnerhet fokuseras på dispositioner såsom värdepapperslån (eng. securities lending) och blankning (eng. short selling). Det torde vara mycket svårt att föra en talan avseende att en aktieförvärvare skulle vara i ond tro och att denne därigenom inte gjort ett godtrosförvärv av en aktThe purpose of this paper is to examine a number of property- and corporate law aspects within the framework of a transaction of shares, targeting primarily dispositions such as securities lending and short selling. Since it ought to be difficult to bring a successful claim against a share purchaser, claiming that he was in bad faith while acquiring the shares and thus did not make an acquisitio

Language learners must become able to perceive and process new speech sounds in order to segment words and sentences. The process of obtaining these skills is, to a high degree, implicit. However, research attempting to find the neuroanatomical correlates of such an implicit learning system has mostly used artificial grammar or serial reaction time tasks that are lacking in linguistic relevance. ILanguage learning involves implicitly acquiring a sensitivity for novel speech sounds and phonological structure [1]. Implicit learning skill differs between individuals [2] and this individual difference could potentially be reflected in the quality of white matter tracts relevant for speech perception and production [3] or for implicit sequence learning [4]. Implicit learning of speech has been

Despite extensive efforts through various international initiatives to reduce global warming, it has been determined that human induced climate change is here, that the present scale of disruption of the climate is unprecedented and will continue. Increasing weather volatility can be expected, which will most likely increase exposure to weather related hazards, e.g. wildfires, flooding. The aim of

Digital infrastructure and the exercise of authority by social services: the case of social assistance in SwedenThis article explores how digitalisation impacts the discretionary space and decision-making processes of social workers in the administration of social assistance within social services. In the context of increasing digitalisation and automation in public administration, the study exami

Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor tem- perature. However, this control principle cannot take into account heat gains or losses caused by tenants, electrical appliances, the sun, air leakage, etc., which may result in uneven indoor Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor temperature.

I Sverige står värme för 55 % av den totala energianvändningen i bostäder och lokaler, där den nästan uteslutande används till uppvärmning av utrymmen och tappvarmvatten. Fjärrvärme tillgodoser 90 % av svenska flerbostadshus värmebehov medan motsvarande siffra är 3 respektive 80 % för industrier och offentliga lokaler. De olika kundkategorierna skiljer sig åt i användarmönster, både sett till effe
