Efecto del dise o de revestimientos sobre el consumo de potencia en molienda
Valderrama, M.,Magne, L.
Revista de Metalurgia , 1996,
Abstract: Power mill draw was measured in a 290 x 110 mm laboratory batch mill, loaded with balls, cylinders or metal grains. Angle between front face of the lifter and its base-surface are the key parameter to control power consumption. A 45° lifter front angle and about 85 % rotational speed lead to the maximum power draw. As the mill is provided with higher lifter front angles, a decrease in power occurs, and the maximum with respect to the mill velocity is shifted to lower values. For lifter front angle lower than 45°, power consumption at low mill rotational speed is reduced, and the maximum is often moved beyond the critical speed value, which indicates slip of the load. Lifter height has a variable effect upon power draw, depending on the front angle and its relative size compared to the grinding bodies. Generally, an increase in height reduces the maximum power draw, and it is obtained at a lower rotational speed. Low-angle lifters are less sensible to the height. Number of lifter did not show any effect on power draw. Se midió el consumo de potencia en un molino discontinuo de laboratorio de 290 x 110 mm cargado con bolas, cilindros o granallas de tama o uniforme. El ángulo formado por la cara frontal de un levantador y la superficie base de la pieza son el parámetro clave para controlar el consumo de potencia. Los mayores valores se obtienen utilizando levantadores con ángulos de 45° y velocidad de rotación del molino de aproximadamente 85 % de la velocidad crítica. Cuando el molino es equipado con levantadores de alto ángulo de ataque, el consumo de potencia decrece y la velocidad de máxima potencia se desplaza a valores más bajos. Para levantadores con ángulos menores de 45°, el consumo de potencia a bajas velocidades se reduce, incrementándose el máximo más allá de la velocidad crítica en muchos casos, lo que indica resbalamiento de la carga. La altura del levantador tiene un efecto variable sobre la potencia, dependiendo del ángulo de ataque del levantador y su tama o relativo frente a los medios de molienda. La mayor altura reduce el consumo máximo de potencia, que se alcanza a una velocidad de giro más baja. Los levantadores de ángulos menores son menos sensibles a la altura.
Dynamic Simulation of Chemical Engineering Systems by the Sequential Modular Approach
Magne Hillestad,Terje Hertzberg
Modeling, Identification and Control , 1986, DOI: 10.4173/mic.1986.3.1
Abstract: An algorithm for dynamic simulation of chemical engineering systems, using the sequential modular approach, is proposed. The modules are independent simulators, and are integrated over a common time horizon. Interpolation polynomials are used to approximate input variables. These input polynomials are updated before modules are intergrated in order to interpolate output from preceding module(s) and thereby increase coupling and stabilize the computation. Tear stream variables have to be predicted at future time tn+1 and various prediction methods are proposed.
An Implementation of Estimation Techniques to a Hydrological Model for Prediction of Runoff to a Hydroelectric Power-Station
Magne Fjeld,Sverre Aam
Modeling, Identification and Control , 1981, DOI: 10.4173/mic.1981.1.3
Abstract: Parameter and state estimation algorithms have been applied to a hydrological model of a catchment area in southern Norway to yield improved control of the household of water resources and better economy and efficiency in the running of the power station, as experience proves since the system was installed on-line in the summer of 1978.
Psoriasisartritt
Tor Magne Madland
Norsk Epidemiologi , 2009,
Abstract: Psoriasisartritt (PsA) er betegnelsen p en kronisk artrittsykdom som kan oppst hos personer med psoriasis. Det er den nest hyppigste leddgiktssykdom i befolkningen, etter revmatoid artritt (RA), og prevalens hos voksne er estimert til 0,1-0,2%. I artikkelen gis en kort beskrivelse av sykdomskarakteristika, klassifikasjon og behandling, mens hovedfokus er sykdommens epidemiologi i nordiske land. I tillegg til s k i PubMed bygger artikkelen p resultater fra egen unders kelse.

Et lite pekk tesies. Litt om spr ket i Vett og uvett
Nils Magne Knutsen
Nordlit : Tidsskrift i litteratur og kultur , 2005,
Abstract: I det ytre er Vett og Uvett ei ganske lita bok, men den ruver som et storverk i nordnorsk litteratur. Og den har en posisjon i nordnorsk folkeliv og i nordnorsk bevissthet som ingen andre verdslige b ker har hatt - kanskje unntatt Nordlands Trompet. I det ytre ganske beskjeden, alts , men likevel et slags kulturelt landemerke, et fast punkt man som nordlending kan orientere seg ut fra - i flere retninger. Og dette er det ikke vitenskapen eller universitetet eller Bokbadet i NRK eller Dagbladets kultursider som har bestemt, det har vi nordlendinger selv bestemt, og det har vi bestemt gjennom ta boka i bruk, ved dyrke den, ved sitere den, ved la den g inn i v r forestillingsverden, og ved la den glede oss og tr ste oss og l fte oss n r det ser litt m rkt ut.
