Addictive neurons

2017

Since the reward center is considered to be the area tegmentalis ventralis of the hypothalamus, logically its neurons could mainly be responsible for addiction. However, the literature asserts that almost any neurons of CNS can respond to one or another addictive compound. Obviously not only addictive nicotine, but also alcohol, amphetamine, cannabis, cocaine, heroin and morphine may influence dopaminergic cells alone in VTA. Moreover, paradoxically some of these drugs ameliorate symptoms, counterbalance syndromes, cure diseases and improve health, not only those related to the CNS and in adults, but also almost all other organs and in children, e.g. epilepsy.

Lavtemperatur brenselceller

2005

Dokumentet er en del av en eksamensoppgave i MEF4200 Energimaterialer ved UiO høsten 2004. Som del av eksamen i emnet MEF4200 Energimaterialer ved Universitetet i Oslo (UiO) høsten 2004 var oppgaven å skrive en populærvitenskapelig artikkel for avgangselever i videregående skole. Artikkelen presenteres her og omhandler lavtemperatur brenselceller. De brenselcelletypene som beskrives er alkaliske brenselceller, PEM-brenselceller og metanolbrenselceller, alle med en driftstemperatur på normalt under 100 °C, og deres bruksområder.

Do ventilatory parameters influence outcome in patients with severe acute respiratory infection? Secondary analysis of an international, multicentre1…

2021

Purpose: To investigate the possible association between ventilatory settings on the first day of invasive mechanical ventilation (IMV) and mortality in patients admitted to the intensive care unit (ICU) with severe acute respiratory infection (SARI). Materials and methods: In this pre-planned sub-study of a prospective, multicentre observational study, 441 patients with SARI who received controlled IMV during the ICU stay were included in the analysis. Results: ICU and hospital mortality rates were 23.1 and 28.1%, respectively. In multivariable analysis, tidal volume and respiratory rate on the first day of IMV were not associated with an increased risk of death; however, higher driving pr…

Flexibility in otherwise consistent non-breeding movements of a long-distance migratory seabird, the long-tailed skua

2017

Quantifying within- and between-individual variation in animal migration strategies is a first step towards our understanding of the ability of migrants to adjust to changes in the en - vironment. We studied consistency (or, conversely, flexibility) in movement patterns at large (>1000 km) to meso-scales (100−1000 km) during the non-breeding season of the long-tailed skua Stercorarius longicaudus, a long-distance migratory Arctic seabird, using light-based geolocation. We obtained 97 annual tracks of 38 individuals and quantified similarity between routes. Overall, tracks of the same individual were generally within about 200 to 300 km of their previous year’s route, and more similar than t…

La desamortización y enajenación del dominio de Sueca a finales del antiguo régimen: la presencia de Godoy como duque y señor de Sueca

2010

La concesión del ducado de Sueca a Manuel Godoy y la adquisición, mediante pública subasta del término y las pertenencias de esta villa, provocó importantes cambios en la jurisdicción y administración de la anterior posesión de la Orden de Montesa. La modificación en las condiciones de la compra, confirieron al Príncipe de la Paz los mismos privilegios de los que disfrutaba el Rey como Gran Maestre y Administrador Perpetuo, lo que acabó generando tensiones con los vecinos, terratenientes y el propio Ayuntamiento. The granting of the Duchy of Sueca to Manuel Godoy and the acquisition by auction of the territory and the belongings of this town, led to significant changes in the jurisdiction a…

Appetite for destruction: A psychometric examination and prevalence estimation of destructive leadership in Sweden

2021

There is a growing awareness that destructive leadership has a significant negative impact on employe outcomes. However, little is known about the content and dimensionality of this multidimensional concept, and there are few reliable measures available for organizations and researchers to evaluate these behaviors. Based on a representative sample (N = 1132) of the Swedish workforce, the aim of this study is threefold: first, to examine the factor structure and validity of an easy-to-use multidimensional destructive leadership measure (Destrudo-L)in the general Swedish work context; second, to identify destructive leadership profiles using latent profile analysis (LPA), and determine in wha…

Associations between sleep deficit and academic achievement - triangulation across time and subject domains among students and teachers in TIMSS in N…

2022

Abstract Background Sufficient sleep is important to an individual’s health and well-being, but also for school achievement among adolescents. This study investigates the associations between sleepiness, sleep deficits, and school achievements among adolescents. Methods This trend study involved a representative sample of Norwegian adolescents based on the “Trends in International Mathematics and Science Study” (TIMSS), N = 4499 (2015) and N = 4685 (2019) and their teachers. The students were 9th graders from a Norwegian compulsory secondary school. The survey included questions on students’ sleepiness as students reported in 2019 and sleep deficits among students that limited teaching in c…

Phone-Controlled Delivery of NGN Services into Residential Environments

2008

The horizontally layered architecture of the IMS/NGN standards family enables the delivery of services independent of access network and requesting device. In this article, the authors propose a further separation of service control and delivery, allowing the requesting device - in particular a user's mobile phone - to invite other devices (we will focus on DLNA appliances) into the service delivery, enhancing both user experience and service design flexibility. The proposed solution builds on exploiting proximity technologies (e.g. barcodes, NFC) for pairing the control device with a remote environment. Motivated by scenarios, the architecture concepts are explained and a prototype that wa…
